Step-by-step explanation:
It's a question of trigonometry.
You need to remember that tangent (tan) stands for Perpendicular / Base.
So, tan P = QR / PR
By Pythagoras Theorem,
34² = 30² + x²
x² = 34² - 30²
x² = 1156 - 900
x² = 256
x = 16
Now, placing the values,
tan P = 30 / 16
tan P = 1.875

Answer:
Hello there!
The answer to your question is :
<em>C: Finn needs 6 cups of sugar for 4 cakes.</em>
<em>D: Finn needs 1 1/2 cups of sugar for 1 cak</em>e.
Step-by-step explanation:
The graph clearly shows ( sides cups of sugar) (bottom number of cakes)
For sugar you need 6 cups to make 4 cakes
For sugar on the second question you need 1 1/2 cups of sugar to make 1 cake
Multiply 1 1/2 times 6 then divide and your answer is 4. That's 4 cakes out of 6 cups of sugar out of the original cups of sugar ( 1 1/2)
This is the confirmed answer I took the quiz and got 100%
Hopes this helps you!

Answer:
..........
Step-by-step explanation:
This is a stupid question. The teacher who asked this needs to go back to school.
A = x⁴ - 9y²
That's going to be a number. As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L. So the correct answer is the dimensions are L by (x⁴ - 9y²)/L.
They don't want the correct answer. They want you to factor this expression. We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.
We use the difference of two squares, a²-b² = (a+b)(a-b)
A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)
Answer: x²+3y by x²-3y
Answer:
1/4 is the number
a.k.a. 0.25
Step-by-step explanation:
Replace the words "a number" with x
4x + 2 = 3
Then, simplify
4x = 1
x = 1/4
