Answer: 1/15

Step-by-step explanation: A. If 1/3 cup makes 5 rolls, you need to know how many cups make one. (1/3)/5 = 1/15 Take the number of cups for one roll and multiply it by 3. 1/15 x 3 Final Answer = 3/15

B. Take the number of cups you have divided by 1/3 (since you know how many roles this makes) (5 2/3) / (1/3) Final Answer = 17

C. Well, we already solved for this one in A, didn't we? Final Answer = 1/15

If cos x = sin(20 + x) ° and 0°

Varvara68 [4.7K]

Answer:

x = 35°

Step-by-step explanation:

The question is as following

cos x = sin(20 + x)° and 0° < x < 90° , find X?

==============================================

cos x = sin(20 + x)°

sin and cos are co-functions,

which means that: cos x = cos [90 - (20 + x)]

∴ x = 70 - x

∴ 2x = 70

∴ x = 35°

======================

Note: cos θ = sin ( 90 - θ )

Omar says that the least common multiple of 9 and 6 is 54. Which is true about Omar's statement?

Damm [24]

Hey there!

Let's pull out the multiples of each number and see which ones fall in line first.

9,18

6,12,18

The LCM is 18. Therefore, answer B and D are incorrect. A is incorrect because 9 * 6 is 54. Therefore, the answer is C.

I hope this helps!

A child building a tower with Blocks uses 15 for the bottom row. Each row has 2 fewer blocks than the previous row. What formula

xenn [34]

Answer:

B)blocks in 5th row=15+(5-1)(-2)

Step-by-step explanation:

We are given that

Number of block in bottom row=15

Each row has 2 fewer blocks than the previous row

We have to find the formula would you use to find the number of blocks in the 5th row.

Number of blocks in second row=15-2= $15+1(-2)$

Number of blocks in third row=15-2-2= $15+2(-2)$

Number of blocks in 4th row= $15-2-2-2=15+3(-2)$

Number of blocks in 5th row= $15-2-2-2-2=15+4(-2)$

Therefore, number of block in 5th row

$15+(5-1)(-2)$

This is required formula to find the number of blocks in the 5th row

Hence, option B is true.

B)blocks in 5th row=15+(5-1)(-2)
