Answer:306

Step-by-step explanation:

since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.

harina [27]

Answer:

1. y = 10 - x

Step-by-step explanation:

Because he starts off with 10 dollars, and x is the amount he spends on an item, y is showing the change that he would get from paying with a 10 dollar bill, so it's what's left over from that 10 dollars.

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?

GrogVix [38]

Answer: " \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " .

_______________

Step-by-step explanation:

_______________

This is a "unit rate" problem;

that is: we want to solve for a particular quantity per [single] unit.

_______________

→ in this case, per single "hour" ;

_______________

So we convert:

_______________

" 2 gal per 8 hours" ; to the correct number of:

_?_ gal per [single] hr.

_______________

{<u>Note</u>: "gal" refers to: "gallon(s)" ;

"hr" refers to: "hour(s)" .}.

_______________

→ " $\frac{2 gal}{ 8 hr} = [\frac{2}{8}]$ gal / hr. " ;

_______________

→ " { $\frac{2}{8} =$ [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:

→ " $\frac{1}{4} gal /hr$ " ;

_______________

or: write as decimal:

→ " $\frac{1}{4}$ = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

→ " 0.25 gal/hr. "

_______________

Or, when we had:

→ "2/8" gal/hr ;

_______________

Use calculator:

→ " $\frac{2}{8}$ = "2 ÷ 8" ;

= " 0.25 gal/ hr.

_______________

So: The correct answer is:

_______________

" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;

_______________

Express the area A of a circle as a function of its radius, r. Determine the area of a circle whose radius is 11 inches. That

nekit [7.7K]

<h2>Answer with explanation:</h2>

The function represents the area of a circle(A) is given by :-

$A(r)=2\pi r$

To determine the area of a circle whose radius is 11 inches. , we put the value of r=11 inches, we get

$A(11)=2\pi (11)$

Now, we put $\pi=\dfrac{22}{7}$ in the above function , we get

$A(11)=2(\dfrac{22}{7} )(11)\\\\\Rightarrow\ A=56.5714285714\approx56.57$
