Answer: (b)
Step-by-step explanation:
Given
Function for bill calculation is
[tex]\Rightarrow b(x)=\left \{ {{0.15x\quad \quad \quad \, \ \ \ \ x<200} \atop {0.1(x-200)+30\quad x>200}} \right.[/tex]
The consumption is 700 kWh i.e. more than 200
Therefore, bill is given by the second function i.e. [tex]0.10(x-200)+30[/tex]
Substitute 700 for x to get the bill
[tex]\Rightarrow 0.1(700-200)+30\\\Rightarrow 50+30=\$80[/tex]
Hence, option (b) is correct.
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.
Please help me I will give you 16 points I don’t know what that do but I will
Answer:
40
Step-by-step explanation:
The serving sizes, [tex]x[/tex], of 20, 80, and 120 have a required amount of meat in pounds, [tex]y[/tex], of [tex]y=\frac{1}{10}x[/tex] (the number of pounds of meat is equal to 1/10th the serving size)
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.
which line is parallel to y=3/4x+10
1. y=-3/4+1
2. y=4/3x+8
3. y=-4/3-10
4. y=3/4x-6
The answer would be number 4, y=3/4x-6.
This is because both of the equations share the same slope of 3/4x.
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%

Which solutions make this inequality true? 3x>-30?*
X can be - 10
X can be -8
X can be o
X can be -12
x can be 3
Answer:
X can be -8, 0, and 3
Step-by-step explanation:
-8x3=-24
0x3=0
3x3=9
so -24, 0, and 9 are all bigger than -30 because -30 is a negative number.
-24>-30
0>-30
9>-30
Hope this helps!
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

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.

for 1 trial, 3 spinners are spun where each spinner has 3 equal sections labeled 1, 2, and 3. What is the probability that at least two spinners land on 1?
Answer:
80/121
Step-by-step explanation:
For simplicity,
Probabilities of getting a red, a blue or a green in a single spin are, respectively, 4/11, 4/11 & 3/11.
Therefore, probabilities of getting 2 reds, 2 blues or 2 greens in 2 spins are, 16/121, 16/121 & 9/121 respectively.
Then, total probability of getting same colour both times would be 16/121 + 16/121 + 9/121 = 41/121.
Any other option would result in 2 different colours. Thus, the probability of getting two different colours in 2 spins = 1 - 41/121 = 80/121.

Answer:
x = 2
Step-by-step explanation:
If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{6x+2}{x +5}[/tex] = [tex]\frac{24-8}{8}[/tex] = [tex]\frac{16}{8}[/tex] = 2 ( multiply both sides by x + 5 )
6x + 2 = 2(x + 5)
6x + 2 = 2x + 10 ( subtract 2x from both sides )
4x + 2 = 10 ( subtract 2 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Can someone help me with this? i’m struggling urgent help please!!!!
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

. He includes the ratios 4

and 5
6
.
Are these ratios equivalent to 2
3
? Explain your reasoning and longitude help us.
Answer:
The Earth is divided into degrees of longitude and latitude which helps us measure location and time using a single standard. Longitude and latitude lines measure the distance from the Earth's Equator or central axis - running east to west - and the Prime Meridian in Greenwich, England - running north to south.
No, the ratios are not equivalent to 2/3. To create an equivalent ratio, you need to multiply both numbers in the original ratio by the same number.

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.
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

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.

En el numeral 87.684 la cifra de las decimas es la cifra de las centésimas es la cifra de las milésimas es la parte entera de la expresión decimas es en la parte entera, la cifra de unidades es , mientras que la cifra de la decena es
Answer:
La cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.
Step-by-step explanation:
Para responder la pregunta, se debe descomponer el número en cuestión:
87.684
8 = Indica la cantidad de decenas del número, es decir, 8 decenas (80).
7 = Indica las unidades dentro de la decena, es decir, 7 unidades más que 80.
.6 = Indica la cantidad de decenas del entero.
.08 = Indica la cantidad de centésimas del entero.
.004 = Indica la cantidad de milésimas del entero.
Así, la cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.
The equation a + b = c could be true or false.
