Answer:
$4.20
Step-by-step explanation:
you first do 1.75 divided by 5 which gives you .35
so you do .35 times 12 which gives you 4.2
The price of a 12-minute phone call is $4.2.
We have given that,
The price of a 5-minute phone call is $1.75.
We have to determine, the price of a 12-minute phone call.
What is the price?
A price is the (usually not negative) quantity of payment or compensation given by one party to another in return for goods or services.
We first 1.75 divided by 5 which gives you .35
That is,
[tex]\frac{1.75}{5} =0.35[/tex]
[tex](0.35)( 4)=4.2[/tex]
0 .35 times 12 which gives $4.2.
Therefore the price of a 12-minute phone call is $4.2.

1. I'm not completely sure, but these angles seem to be complementary, meaning they add up to 90°. Since 75° + x = 90°, x = 15°.
2. These lines seem to be parallel. ∠4 ≅ ∠1 because they are vertical angles, ∠5 ≅ ∠1 because they are corresponding angles, and because ∠8 ≅ ∠4 (corresponding angles), ∠8 ≅ ∠1 as well. The final answer is ∠4, ∠5, and ∠8. Hope this helps!

Given f(g(x)) = 15x+1 and f(x) = 5x+1. What is g(x)?
Please answer quickly!!
Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".

In a right triangle, one leg is 20 cm and the hypotenuse is 30 cm. To the nearest hundredth of a cm, find the length of the missing leg. Formula and diagram required. Include units in your answer.
Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
Answer:
22.36
Step-by-step explanation:
For this question we need to utilise Pythagoras theorem. Pythagoras theorem states that a² + b² = c² so the sum of the leg's squared will equal the hypotenuse squared. In this question we are given the hypotenuse so we will have to rearrange the equation to find the value of the leg,
→ a² + b² = c²
⇒ Substitute in the values
→ 20² + b² = 30²
⇒ Simplify
→ 400 + b² = 900
⇒ Minus 400 from both sides to isolate b²
→ b² = 500
⇒ Square root both sides to find the value of the leg
→ b = 22.360679775 cm
The length of the missing leg is 22.36 cm to nearest hundredth considering one leg is 20 cm and the hypotenuse is 30 cm.

and m\angle B=(7x-15)^{\circ}∠B=(7x−15)
∘
, then find the measure of \angle B∠B.
Answer:
To find the complement of an angle x, subtract x's measurement from 90 degrees: 90 degrees - x degrees = the measure of x's complementary angle. To find the supplement of an angle y, subtract y's measurement from 180 degrees: 180 degrees - y degrees = the measure of y's supplementary angle.

What is the volume of a sphere with a radius of 21 units?
A. 9261 pie units 3
B. 12,348 pie units 3
C. 588 pie units 3
D. 37,044 pie units 3
Answer:
B
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius ), thus
V = [tex]\frac{4}{3}[/tex]π × 21³
= [tex]\frac{4}{3}[/tex]π ×9261 = [tex]\frac{4(9261)}{3}[/tex]π = 12348π units³ → B
Answer: B: 12,348π units³ which is 38,772.72 units³
Step-by-step explanation:
The formula of the volume of a sphere is V = [tex]\frac{4}{3}[/tex]πr³
Since we know that the radius is 21, we can fill in the given numbers:
V = [tex]\frac{4}{3}[/tex]π(21)³
Now, the new formula is V = [tex]\frac{4}{3}[/tex]π(9,261) = 38,772.72
The width of a poster is 8cm less than the length. The perimeter is more than 184
cm. If the length and width are both integers, what is the minimum dimension for
the length?
Answer:
Denote the length is a, then the width is a - 8.
The perimeter is more than 184:
=> 2 x ( a + a - 8) > 184
=> 2a - 8 > 92
=> 2a > 100
=> a > 50
=> a = 51
=> Minimum dimension for the length: a = 51

A scale drawing is made to enlarge a picture by using a scale factor of 3. The enlarged picture is 9 inches by 15 inches. What are the dimensions of the original picture? 3 inches by 5 inches 3 inches by 15 inches 6 inches by 12 inches 27 inches by 45 inches
Answer:
3 inches by 5 inches.
Step-by-step explanation:
The scale factor is 3 so the original lengths are 1/3 of the enlarged , so the answer is 9/3 by 15/3
= 3 by 5.
The dimensions of the original picture is 3in by 5in
Scale factors and dimensionLet the original dimension of the drawing be x in by y in
If the dimension of the enlarged picture is 9 inches by 15 inches after using a scale factor of 3, then;
x = 9/3 = 3in
y = 15/3 = 5in
Hence the dimensions of the original picture is 3in by 5in
