There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me

i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)

THE ANSWER IS 68.9 CM

which of the folowing could be the equation for a parabola that opens to the left with vertex (-17, 2)
KATRIN_1 [288]

Answer:

x = a(y+17)^2 + 2 where a < 0

Step-by-step explanation:

Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.

Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.

Substituting these in, we find that the equation is

x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

I hope this helps! :)

bogdanovich [222]
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.

One batch of walnut muffins uses 1 1/3 cups of walnuts. How many cups of walnuts are needed to make 3 3/4 batches of muffins?
dusya [7]

Answer:

5 cups of walnuts are needed.

Step-by-step explanation:

This question can be solved using a rule of three.

One batch of walnut muffins uses 1 1/3 cups of walnuts.

So one batch of walnut muffins uses 1 + \frac{1}{3} = \frac{4}{3} cups of walnuts.

How many cups of walnuts are needed to make 3 3/4 batches of muffins?

How many cups are required for 3 + \frac{3}{4} = \frac{15}{4} batches.

1 batch - (4/3) cups

(15/4) batches - x cups

x = \frac{4}{3} \times \frac{15}{4} = \frac{60}{12} = 5

5 cups of walnuts are needed.
