Answer:
Step-by-step explanation:
Cross section is the isosceles trapezoid.
<u>Area of trapezoid:</u>
We have one of the bases and the height.
Let the difference of the base lengths is x.
<u>We have:</u>
- (x/2)/h = cot θ ⇒ x = 2h cot θ
<u>The area is:</u>
- A = 1/2(w + w + 2h cot θ)h = (w + h cotθ)h
Answer:
Step-by-step explanation:
4(5x-2y=9)
-2(3x+4y=-5)
20-20x-8y=36
+6x-6x-8y=10
36-20x=10+6x-6x
36-36-20x-6x=10
-26x=10-36
-26x/-26=-26/-26
x=1
Answer:
I believe the answer is the second one but take precaution i haven´t done them in a few years so be careful.
Step-by-step explanation:
So she has

cups of yogurt for making fruit parfaits, and each parfait requires

cup of yogurt. This would imply that we would have to divide the first fraction by the second fraction to find out how many parfaits she can make.
Skip, switch, flip (I believe that's how the statement goes?) When you are dividing a fraction, you skip the first fraction, switch the division sign into a multiplication sign, and flip the second fraction so the denominator is the numerator, and the numerator is the denominator. That would make it :

×

: And 14 × 6 is 84, and 6 times 2 is 12. That would mean that we divide

.
84 divided by 12 is 7. She can make
7 parfaits.
Answer:
81π cm²
OR
≈254.34 cm²
Step-by-step explanation:
The area formula for a circle is π×r².
Since the radius of the pizza is 9, we get:
π×9²=
2×π×81=
81π or ≈ 254.34 cm²
