She already has 32$. And makes 4$ every hour of mowing lawns.

4 + 4 + 4 + 4 + 4 + 4 + 4 = 30 = 4 x 7 which equals 30



Joan needs to work 7 hours in total to get 28$.

Joan has 32$. And makes 4$ every hour of mowing lawns.

60-32=28.

So what we will do to solve this problem is multiply 7 by 4.

7x4= 28.

32+28=60.

This means that Joan needs to work 7 hours in total to earn $28.

In the figure below line DE is parallel to line FG and transversal AG
Arturiano [62]

Answer: The answer is 147° and 33°.

Step-by-step explanation:  We are given a figure in which the line DE is parallel to the line FG and AG is a tranversal. We are to find the value of 'x' and 'y' from the figure.

Also, given that

∠ABE = (5y - 18)°.

We can see from the figure that ∠DBG and ∠ABE are vertically opposite angles, so they must be equal.

That is,

\angle DBG=\angle ABE\\\\\Rightarrow x=5y-18\\\\\Rightarrow 5y-x=18.~~~~~~~~~~~~~~~(i)

Also, since ∠DBG and ∠FGB are interior angles on the same side of the transversal, so their sum is 180°.

That is

\angle DBG+\angle FGB=180^\circ\\\\\Rightarrow x+y=180.~~~~~~~~~~~~~~~~~(ii)

Adding equations (i) and (ii), we get

y+5y=18+180\\\\\Rightarrow 6y=198\\\\\Rightarrow y=33,

and from equation (ii), we get

x=180-33=147.

Thus, x° = 147° and y° = 33°.

What is the answer to this please help asap
FromTheMoon [43]

Answer:

19°

Step-by-step explanation:

m<A + m<B + m<C = 180°

a + 17° + 49° + 5a = 180°

6a + 66° = 180°

6a = 114°

a = 19°

Alex needs to buy compressed air to fill empty cylindrical tanks for his tire store. Each tank is 12 feet deep and has a radius
dedylja [7]
So
volume=height times area of base
base =circle so
area of base=area of circle=pir^2
volume=h(pi)r^2
h=12
r=6
pi=3.14 aprox
subsitute
volume=12(3.14)6^2
volume=12(3.14)36
volume=1356.48
that is vol of 1 tank
1356.48 times 5=6782.4

answer is 6782.4 ft^2 or D
