A varsity boys' basketball team has a ratio of seniors to juniors that is 7:4.
The varsity girls' basketball team has a ratio of seniors to juniors that is 3 to 2. If each team has 12 juniors, which team has more seniors
Answer:
The boys' team has more seniors
Step-by-step explanation:
If each team has 12 juniors,
Step 1
For the boys' basketball team, lets find the total number of people on the team
A varsity boys' basketball team has a ratio of seniors to juniors that is
7:4 = seniors : juniors
Sum of proportion
= 7 + 4 = 11
Let the total number of people on the team = x
Hence:
4/11 × x = 12
4x/11 = 12
Cross Multiply
4x = 11 × 12
x = 11 × 12/4
x = 33 members
The number of seniors is calculated as
33 members - 12 juniors
= 21 seniors
Step 2
For the girls' basketball team, lets find the total number of people on the team
The varsity girls' basketball team has a ratio of seniors to juniors that is 3 to 2.
= 3:2 = seniors : juniors
Sum of proportion
= 3+2 = 5
Let the total number of people on the team = x
Hence:
2/5 × x = 12
2x/5 = 12
Cross Multiply
2x = 5 × 12
x = 5 × 12/2
x = 30 members
The number of seniors is calculated as
30 members - 12 juniors
= 18 seniors
Therefore, from our above calculations, the boys' team has more seniors

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.

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
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?
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

Have a great day.
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

Answer:
they are NOT similar!
Step-by-step explanation:
the angles are not conguent or they are not the same in words
the don't add up with the same sum of angles,
so your explanation would be:
45 plus 29 has a sum of 74 for the right triangle and the left triangle has angles 106 degrees plus 29 degrees with a sum of 135 degrees, there-fore the triangles aren't similar because the angles are not equal to each other
9514 1404 393
Answer:
∆AFN ~ ∆SHE . . . . AA~
Step-by-step explanation:
The third angle in triangle HSE is ...
180° -45° -29° = 106°
This means two angles in ∆SHE match two angles in ∆AFN. (106° and 29°) The triangles are similar by AA~.
Listing vertices in order of smallest-to-largest angles, the similarity statement is ...
∆AFN ~ ∆SHE . . . . AA~

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.

Write the equation in standard form for the circle with center (0, -8) and radius 6.
Answer:
(x)^2 + (y+8)^2 = 36
Step-by-step explanation:
The standard form for an equation for a circle is
(x-h)^2 + (y-k)^2 = r^2 where ( h,k) is center of the circle and r is the radius
(x-0)^2 + (y- -8)^2 = 6^2
(x)^2 + (y+8)^2 = 36
Consider the equation.

Person 1 can do a certain job in twenty-one minutes, and person 2 can do the same job in twenty-eight minutes. When
completing the job together, which expression would be used to represent the amount of work done by person 1?
A. 21
B. X/21
C. 21x
D. 1/21
Answer:
C) x/21
Step-by-step explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.
