For 10 hours of job Gerald earns 8*10=80$
For 11 hours Gerald earns 8*10+9n. n - number of working hours over 10 hours.
if Gerald work 16 hours, then he work 6 hours after 10, so n=6
8*10+9*6=80+54=134$
Answer: Gerald earns 134$ if he works 16 hours in one week.
Sorry for my bad English pls:)
The consecutive positive integers would be: x and (x+1),
We would have to solve the following equation to find these numbers:
x(x+1)-[x+(x+1)]=29
x²+x-2x-1=29
x²-x-30=0
x=[1⁺₋√(1+120)]/2
x=(1⁺₋11)/2
We have two possible solutions:
x₁=(1-11)/2=-5 then: (x+1)=-5+1=-4 This is not the solution.
x₂=(1+11)/2=6 then: (x+1)=6+1=7 This solution is right.
Answer: the numbers would be 6 and 7.
Answer:
5 units
Step-by-step explanation:
Image of the trapezoid is attached.
To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.
The formula for area of a trapezoid is:
Here, a and b represents the bases of the trapezoid.
a = 6
b = 10
h which represents height is unknown.
A = 40
Substitute figures:
Solve for h:
The height of the trapezoid is 5 units
