Lucas and Tony were trying to solve the equation: x^2=16x+25 Lucas said, "The x^2, squared term is isolated, so I"ll take the square root of both sides and solve." Tony said, "I'll solve using the quadratic formula with a=1,b=16, an c equals 25." Whose solution strategy would work? Choose 1 answer:
Answer:
Tony's solution strategy
Step-by-step explanation:
Given the equation that Lucas and Tony trying to solve expressed as: x^2=16x+25
This can be written in standard form as x^2 - 16x - 25 = 0
This can then be factorized using the general formula
x = -b±√b²-4ac/2a where a, b and c are constants
From the given expression;
a = 1, b = -16, c = -15
Hence the best strategy that would have worked based on the explanation is Tony's

Which polynomial is factored completely? g Superscript 5 Baseline minus g 4 g cubed + 18 g squared + 20 g 24 g squared minus 6 g Superscript 4 2 g squared + 5 g + 4
Answer:
It's D on Edge 2021
I did the assignment
The polynomial that is factored completely is one that can not be factored again is 2g² + 5g + 4. Therefore, option D is the correct answer.
What is the factorisation of a polynomial?Factorisation of a polynomial is the decomposition of a polynomial into smaller polynomials.
Thus, the polynomial that is factored in completely is the polynomial that can not be decomposed again.
Now,
g⁵ - g = g(g⁴ - 1) (it can be factored)
4g³ + 18g² + 20g = 2g(g + 2)(2g + 5)
24g² - 6g⁴ = 6g²(4g² + g²)
2g² + 5g + 4 cannot be factored again. It is already factored completely

what percentage of the 100 square grid is shaded
Answer:
25%
Step-by-step explanation:
Simply count the fully shaded squares; there are 22 of them. Then count the 1/2 filled squares; there are 6 of them. Combine half squares to make whole squares and you end up with 3 full squares.
Add 22+3 to get 25 -- 25 out of 100 = 25%

With your bare feet, stand with one foot on a rug, and the other foot on a tile, linoleum, or wood floor. Which one feels colder? Which one is really colder? Explain what is going on in a paragraph
Answer:
The tile feels colder because it's a heat conductor and moves heat rapidly away from your skin which is much warmer than the air temperature. The rug is a heat insulator. The rug slows down the flow of the heat which makes it feel warmer.

Can u guys hurry up pleasee The manager of a local appliance store wants to conduct a customer satisfaction survey. Which population should the manager survey? A.Sales people in the store. B.People in charge of repairs at the store. C.People who bought a major appliance from the store. D.Prospective buyers who visit the store.
C. People who bought a major appliance from the store.
Step-by-step explanation:A customer satisfaction survey is a market survey carried out to analyze how satisfied users or customers are in using or consuming a particular product or service. Basically, it has to be carried out on the customers themselves. By costumers, we mean those that have bought and/or used the service or product.
For the local appliance store, the manager should survey people that have bought at least one major appliance from the store. Those are the right people that should make up the population to be surveyed. This is because;
i. They are the consumers of the product.
ii. They have bought and definitely used the product.
iii. They have some usable and useful experiences since they have handled the product.

An oil-drilling rig has dug a hole to a depth of -60 ft. after one full day and night of continuous
use. The rate of the rig stayed constant over that time.
Part A: The rig will be used to dig a second hole with a depth of -150 ft at the same rate as
before. How many hours will the rig take to complete digging the hole?
Answer:
It will take 60 hrs
Hope this helped!
Answer:
It would take 60 hours for the rig to complete digging the -150 ft. hole.
Step-by-step explanation:
Hint: Using ratios will help solve questions like this one.
The first hole was dug -60 ft. below the surface for a whole day and night. A day lasts 12 hours and the same goes for a whole night. That's 24 hours in total. This will help answer Part A. A second hole was dug -150 ft. below the surface with the same rate as the first hole. Let's put this into a ratio.
-60 : 24
-150 : ?
Finding the scale factor in ratios will help solve for the missing value. We can divide -150 by -60 which results in 2.5. Multiply 2.5 by 24 and you will get 60 hours as your final answer. I hope you will find this helpful! :D

Nala and lily are playing a dice game where they score points. After one round, the ratio of nala point to lily's point is 7 to 9. If nala has 14 more points than lily, determine how many points lily has.
Answer:
Lily has 63 points and Nala has 49.
Step-by-step explanation:
Since Nala and Lily are playing a dice game where they score points, and after one round, the ratio of Nala's points to Lily's points is 7 to 9, if Nala has 14 more points than Lily, to determine how many points Lily has se you must perform the following calculation:
9 - 7 = 2
14/2 = 7
7 x 7 = 49
7 x 9 = 63
63 - 49 = 14
Therefore, Lily has 63 points and Nala has 49.
Suppose you have a bag with 50 letter tiles in it and 23 of the tiles are the letter Y. If
23
you pick a letter tile at random from the bag, the probability that it is the letter Y is Suppose

another bag has 200 letter tiles in it and 172 of the tiles are the letter Y. Write the probability of
picking a tile that is the letter Y as a fraction and as a percent. From which bag are you more likely
to pick a tile that is the letter Y?
Answer:
23
Step-by-step explanation:
234Suppose you have a bag with 50 letter tiles in it and 23 of the tiles are the letter Y. If
23
you pick a letter tile at random from the bag, the probability that it is the letter Y is Suppose
50
another bag has 200 letter tiles in it and 172 of the tiles are the letter Y. Write the probability of
picking a tile that is the letter Y as a fraction and as a percent. From which bag are you more likely
to pick a tile that is the letter Y?
The probability of picking the letter Y from bag of 50 letters is 23/50 or 0.46 or 46% and probability of picking the letter Y form bag of 200 letters is 172/200 or 0.86 or 86%. as the probability of getting the letter Y is more in second bag this it is better to pick the bag containing 200 letters.
What is a probability?The probability explains the chances of happening a event. The probability of an event is a number between 0 and 1, where, 0 indicates impossibility of the event to happen and 1 indicates certainty of the event to happen.
From the question it is said that a bag of 50 letter contain 23 Y letters. Thus the probability of the letter Y picking is 23/50 i.e, number of times the letter Y can come out if we pick the letters 50 times. So, it is certain that 23 Y letters can come out.
23/50= 0.46 or 46%
And if the bag contain 200 letters in which 172 are Y letters then the probability to pick Y is 172/200
172/100 =0.86 or 86%
As the chance to get Y letter is mor in bag containing 200 letters thus pick this bag.
thus the 1st bag probability is 46% and for 2nd bag is 86%. Hence choose 2nd bag

Answer:
Similar by SAS
Step-by-step explanation:
If you multiply the two given sides by 3/2 you will get the sides for the large triangle
3/2 * 10 = 30 / 2 = 15
3/2 * 24 = 72 / 2 = 36
Therefore they are similar by SAS postulate for similarity. Notice that the right angle is between the legs of the triangle. That is the main qualification that allows you to use SAS for similarity.
Find the other two angles of both the triangles, if they were similar then the triangles are similar
Math/Trigonometry!!!!!!!!!!!!!!!!!!!!!!! 22 pts.
Answer:
Approximately 1,320 feet.
Step-by-step explanation:
Let one person be x miles from the skycraper, then the other one will be 5 - x miles away from it.
So we have the 2 equations:
tan 4 = h/x
tan 10 = h/(5 - x) where h is the height of the skyscraper
From the first equation:
h = x tan 4
Substituting in the second equation:
tan 10 = x tan 4 / (5 - x)
5 tan 10 - x tan 10 = x tan 4
x tan 10 + x tan 4 = 5 tan 10
x = 5 tan 10 / ( tan 10 + tan 4)
= 3.58 miles
h = 3.58 * tan 4
= 0.25 miles
= 1320 feet approx.

Find the center and raduis of the circle
Answer:
B
Step-by-step explanation:
Because the equation can be written in the form (x-p)^2+(y-q)^2. So it represents a circle with the radius r=3 and the center of (5,0).
Answer:
C
Step-by-step explanation:
The circle equation (x-a)²+(y-b)²=r² has a radius of r and a center of (a,b).
You can expand your equation from (x-5)²+y²=9 to (x-5)²+(y-0)²=3².
Using this information, you can see that a=5, b=0, and r=3.
Therefore the center is (5,0) and the radius is 3.

hope it helps
Answer:
Step-by-step explanation:
Answer:
A1. The answer is option (b) 1/10
A2. The answer is option (b) 13.4 cm²
A3. Shaded area not provided
A4. The answer is option (b) Unlike Fractions
A5. The answer is option (d) 20
A6. The answer is option (b) 21/23
A7. The answer is option (c) 5/27
Step-by-step explanation:
A1. We multiply the denominators (the numbers on the bottom) and the numerators (the numbers on top) to multiple fractions. As a result, for (1/2) x (1/5), we have
(1/2) × (1/5) = (1 × 1) / (2 × 5) = 1/10.
A2. Multiplying the length by the breadth yields the area of a rectangle. The dimensions in this instance are 6.7 cm in length and 2 cm in width. So, the area may be determined as follows:
Area = length × breadth = 6.7 cm × 2 cm = 13.4 cm².
Hence, the correct answer is (b) 13.4 cm².
A3. Please provide the shaded area.
A4. Fractions that have different denominator are called unlike fractions.
So the answer is option (b)
A5.Let us suppose India played 'x' number of matches
According to the Question, India won 3/5 of its matches, which implies that they won 3/5 * x matches.
It is also mentioned that India won 4 more matches than it lost against New Zealand. Therefore, the number of matches India won against New Zealand is 4 more than the number of matches it lost against New Zealand.
From this, we can set up the equation:
3/5 * x = (x/2) + 4
Multiplying both the sides by 10, we have
6x = 5x + 20
subtracting 5x from both sides:
6x - 5x = 5x - 5x + 20
x = 20
Hence, India played 20 matches.
A6. When the numerator is less than the denominator, the fraction is said to be proper fraction. Hence among the given options, 21/23 fits the best.
Hence option (b) is correct
A7. To find what should be added to 21/27 to make it 26/27, we need to calculate the difference between the two fractions.
Let us suppose that we need to add x
=> 21/27 + x = 26/27
=> x= 26/27 - 21/27 = 5/27
Therefore, the answer is (c) 5/27.

However, for the row with a serving size of 40, the number of pounds of meat is equal to [tex]\frac{6}{40}=\frac{3}{20}[/tex] the serving size. Therefore, the serving size of 40 has a different ratio of serving size to pounds of meat than the other ratios.
