30 is 150% of what number?
A 180
B 20
C 15
D 45
Answer:
B) 20
Step-by-step explanation:
30 = 150% × Y
30 = 150/100 x Y
Y = 30 x 100 divided by 150
Y = 20.
Faster way: 30 x 100 divided by 150.
Hope this helps!

MATH SMARTIES I WILL GIVE BRAINLIEST (the highlighting was from my teacher btw) PLEASE GIVE EXPLINATION ALSO THANK YOU
Answer:
1) D.208
2) C.112
Step-by-step explanation:
so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together
l= length
w=width
a=area
4*8=32
4*8=32
6*4=24
6*4=24
6*8=48
6*8=48
48+48+24+24+32+32=208
208[tex]cm^{2}[/tex]
for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.
for the triangles you're gonna wanna use the equation 1/2b*h=a
b= base
h=height
a=area
7*4=28
7*4=28
7*4=28
7*4=28
28*4=112

A rectangular city lot has an area of 1,000 square meters. If the length of the lot is 10 meters more than twice its width, find the length and width. Write the quadratic equation.
Answer:
Length of the Area = 50mtrs
Width of the Area = 20mtrs
Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans

Answer:
The constant of proportionality is 3.
Step-by-step explanation:
Constant of proportionality is found by doing k = [tex]\frac{y}{x}[/tex]. Point (2,6) is on the line, so if we plug in point (2, 6) into the equation to solve for the constant of proportionality, we get [tex]k=\frac{6}{2}[/tex] or k = 3. The constant of proportionality is 3.

Plz, answer CORRECT!
a. it is not, because dividing 1.875 by 500 would not equal 0.015.
b. each piece of paper would equal 0.00375.
A pizza shop sells pizzas for $7.50 each plus $1.25 per topping. The total price of the pizza can be determined by the
function P (t) = 7.5 +1.25t where t is the number of toppings ordered and P(t) is the total price of the pizza. The shop has a delivery policy that all orders must have a minimum of 2 toppings and a maximum of 5 toppings to qualify
for home delivery. Which of the following represents the range of this situation?
{2, 3, 4, 5}
{10, 11.25, 12.5, 13.75}
0 < P (t) < 5

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
Answer:
50 degrees
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. We would set up the equation like this:
2x+18 + 4x+11 + 55 = 180
Combine like terms:
6x + 84 = 180
Solve for x:
6x = 96
x = 16
We substitute 16 back in for x and see the measure of the smallest angle.
2(16)+18 = 50
4(16)+11 = 75
55
The smallest angle here in 50 degrees.
Answer:
2x + 18 = 50
Step-by-step explanation:
2x + 18 + 4x + 11 + 55 = 180
6x + 84 = 180
180 - 84 = 96
6x = 96
96/6 = 16
x = 16
2(16) + 18 = 50
55
4(16) + 11 = 75
