Answer:

38 = B

39 = C

40 = C

Step-by-step explanation:

38 = although this may be a frations look at it in a different way.

A problem I had was 90 over 5 which I had to divide by. Therefore your answer is B.

39 = Now with a lot of varibles you will encounter later on, when a letter is next to a number like this: 3t, then you always miltiply.

40 = For this to be C you basically have to multiply the number of hours by the number of miles. Which comes to the concept talked about in the last explanation.

Hope this helps, please give brainliest if it does.

Step-by-step explanation:

Given parameters:

Pounds of strawberry picked by Lexi =2 $\frac{7}{10}$

Pounds of strawberry eaten by Lexi sister = $\frac{7}{8}$

Unknown:

Pound of strawberry Lexi's sister ate = ?

Solution:

This is a fraction word problem.

Let pound of strawberry eaten by Lexi's sister = K

We can establish that:

In the triangle below,<br> y = [ ? ] cm. Round to the<br> nearest tenth.

sattari [20]

Answer:

The answer is

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find y

To find y we use cosine

cos∅ = adjacent / hypotenuse

From the question

y is the adjacent

The hypotenuse is 15

So we have

$\cos(35) = \frac{y}{15} \\ y = 15 \cos( 35 ) \\ y = 12.28728$

We have the final answer as

<h3>12.3 cm to the nearest tenth</h3>

Hope this helps you
