Answer:

D: 10x + 5y

Step-by-step explanation:

If we substituted the x and y values in all of these equations, these are the equations and sums we would get:

A: 18 + 54 = 72

B: 30 + 90 = 120

C: 36 + 81 = 117

D: 60 + 45 = 105

Because we now know all of the sums for these equations, we can rule out A, B, and C because they don't have the correct answer that we got when we evaluated the expression which was 105. The only possible option would be D.

(sorry if this is confusing)

What is the answer to number nine also how do I solve for it? Thanks:)

Well the whole ratio is 14 sooooo
98 ÷ 14 =7

for food tents it would be 9 x 7 which is 63

And for retail tents 5 x 7which is 35

so the whole ratio is 63: 35

Can someone please help me with this ?

I believe the area is 704

the area of the square is 484
the area of the triangle is 220
484+220=704

The hypotenuse of a right triangle measures 10 inches and the side opposite to <0 one of the non right angles is 5 inches lon

Sin = Opposite/ Hypotenuse
Sin (theta)= 5/10
Sin^-1(5/10)=30
theta=30

What is the sum in simplest form for 5/8+2/5

Bogdan [553]

(5/8)+(2/5)=

so you need a common den so in this case its 40

so we multiply to get 40 like

(5/5)(5/8)+ (2/5)(8/8)=

25/40 + 16/ 40 = 41/40

Answer:

(a) 22 is not the correct value of h

(b) 164 ft²

Step-by-step explanation:

(a) Apparently, the formula ...

A = 1/2bh

was used. We recognize the base of the triangle is 16 feet, so apparently the formula was used with h=22.

22 is the side length, not the perpendicular distance from the base to the opposite vertex.

The computed value is not the area because 22 is not the height.

(b) Given three side lengths, an appropriate formula is Heron's formula:

s = (a+b+c)/2 and A = √(s(s-a)(s-b)(s-c))

Here, we have ...

s = (22 +22 +16)/2 = 30 and A = √(30(8)(8)(14) = 16√105 ≈ 163.95

The area is about 164 square feet.

(164 ft²)($12.25/ft²) = $2009
