The table below shows the heights of several books. Jean stacks a dictionary on top of her novel. How high is the stack of the t
aev [14]

<u><em>Answer:</em></u>

The height of the stack = 5\frac{1}{4} in

<u><em>Explanation:</em></u>

We are given that Jean stacks a dictionary on top of a novel.

This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.

<u>From the givens, we have:</u>

height of dictionary = 4\frac{1}{2} in

height of novel = \frac{3}{4} in

<u>Now, adding the two height, we will have:</u>

Total height of stack = height of novel + height of dictionary

Total height of stack = \frac{3}{4}+4 \frac{1}{2} = \frac{3}{4}+ \frac{18}{4}= \frac{21}{4}=5 \frac{1}{4} in

Hope this helps :)

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
bija089 [108]

Answer:

8.8

Step-by-step explanation:

Alright so since you know the length of the side opposite the 27 degree angle and you need to find the hypotenuse, you'll use sin (opposite/hypotenuse) . so you do sin 27= 4/x and then when you do these trigometric ratios something my geo teacher taught me is that if the variable is in the denominator then you have to do the length of the side you know /sin/cos/tan of whatever angle you know. so here you insert in your calculator 4/sin 27 (make sure ur calculator is in degree mode you can check this by doing sin 30 and seeing if it equals 1/2 and if it doesnt you need to search online on how you do degree mode) and you get 8.8108. which rounds to 8.8
