Answer:
15.7 percent of 80 = 12.56
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$80=100\%$
Step 4: Similarly, $x=15.7\%$.
Step 5: This results in a pair of simple equations:
$80=100\%(1)$.
$x=15.7\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{80}{x}=\frac{100\%}{15.7\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{80}=\frac{15.7}{100}$
$\Rightarrow x=12.56$
Therefore, $15.7\%$ of $80$ is $12.56$

(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°

Little Caesar's is offering a special where you can buy a large pizza with one
cheese, one vegetable, and one meat for $7.99. There are five kinds of cheese, 6
vegetables, and 8 meats to choose from. How many different variations of the special
pizza are possible?
Answer:
There are 240 variations
Step-by-step explanation:
On one pizza, there are 3 types of toppings, and different variations for each. In order to figure out how many total variations there are, you need to multiply each variation by the other:
5 types of cheese x 6 types of vegetables x 8 types of meat
= 240 variations of the pizza
A chess piece is 15 centimeters tall, and its shadow is 13 centimeters long. How far away is the top of the chess piece from the end of its shadow? Round to the nearest tenth.
Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

Solve the equation:
8b = 5.6
Answer:
b = 0.7
Step-by-step explanation:
to solve the equation, you must isolate "b" so the variable is by itself,,
to do this, divide both sides of the equation by 8:
8b = 5.6
b = 5.6/8
now, simply divide 5.6 by 8 to get your answer,,
b = 5.6/8
b = 0.7

How would you write y = 2x - 3 in function notation? *
Answer:
f(x)=2x-3
Step-by-step explanation:
To write an equation in function notation change the y to an f(x). Then, if you plug something in for x also replace it in f(x). For example, if x=3 then the equation would be f(3)=2(3)-3.

3(8 - 4x) = 12
Please help. You have to use distributive property to solve.
Answer:
x=1
Step-by-step explanation:
First, we distribute the 3 to the 8 and the 4x.
Now we have 24-12x=12
Then, we subtract 24 from 12
Now we have -12x=-12
Finally, we devide -12 by -12
Now we have x=1

6. In a jar of 650 marbles, 20% of the marbles are red.
How many marbles are not red
Answer:
Step-by-step explanation:
20% of 650
1/5 of 650
130=red
520= not red
Answer:
520
Step-by-step explanation:
20% are red which means 130 are red
650-130= 520
or you could look at it this way
if 20% is red that means 80% is not red
80% of 650 is 520
