Answer:

A=20,000 m2 per year

Step-by-step explanation:

we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m

V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2

A school has 360 students. 4/9 of them are girls. 3/5 of them are girls below the age of ten. How many girls are in the school a
quester [9]

To find total number of girls multiply total students by the fraction of girls:


360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.


If 3/5 are below the age of ten, that means 2/5 are above the age of ten.


Multiply the total number of girls by 2/5:


160 x 2/5 = 320/5 = 64


There are 64 girls above the age of ten.

In 2021 Florida's minimum wage will be $10 per hour. In 2026 the minimum wage will increase to $15 per hour. What is the percent
nevsk [136]

Answer:

50% value change.

Step-by-step explanation:

A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.

Therefore, $15 is a 50% percent change from $10.

What are the slope and y intercept of the linear function? Please help
kow [346]
FIND THE SLOPE
The line passes through (0,1) and (2,0)
Use formula of the slope to find the slope
m = (y₂ - y₁)/(x₂ - x₁)
m = (0-1)/(2-0)
m = -1/2
The slope is -1/2

FIND THE Y-INTERCEPT
The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
