Answer:

C. 69 (nice)

Step-by-step explanation:

Sine: Opposite side over hypotenuse

Cosine: Adjacent side over hypotenuse

Tangent: Opposite side over adjacent side

Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.

cos(O)=5/14

O=arcsin(5/14)≈69.0752

The answer is 69.

SOMEONE PLEASE ANSWER THIS FOR MY FIFTH GRADE COUSIN...IM NOT SMARTER THAN A FIFTH GRADER CLEARLY
adelina 88 [10]

Answer:

AJ picks 252 pounds

Step-by-step explanation:

Lets define the following letters for each name:

A is AJ  

B is Blaze

L is Laurence

J is Jack

Now we will analyze the phrases one by one:

Blaze picks three times as many as Laurence means:

B = 3 * L

Jack picks twice as many as Blaze.  

J = 2 * B, ans using the previous one lets substitute B with 3 * L

J = 2 * B = 2 * (3 * L)

J = 6 * L

Aj picks three times as many as Laurence.  

A = 3 * L

The total weight of the oranges is 1092 pounds.  

A + B + J + L = 1092

We replace A, B & J in the last equation, with the previous results:

A + B + J + L = 1092

(3*L) + (3*L) + (6*L) + L = 1092, grouping using L as common factor:  

(3+3+6+1) * L = 1092

13 * L = 1092, then isolating L:

L = 1092 / 13

L = 84 pounds (for Laurence)

Finally replacing L in the previous equations:

A = 3 * L = 3 * 84 = 252 pounds (for Aj)

B = 3 * L = 3 * 84 = 252 pounds (for Blaze)

J = 6 * L = 6 * 84 = 504 pounds (for Jack)

olga nikolaevna [1]

We're told that distance traveled in t hours is 400t. So the distance traveled in 3 hours is 400(3), or 1200 miles.

Paul's Pizzeria sells 45 cheese pizzas and 20 pepperoni pizzas each week. What is the ratio of cheese pizzas to pepperoni pizzas
Inga [223]
A ratio can be written 3 ways. 

1. a to b

2. a:b

3. a 
   ----
    b

Now when we are working with ratios we ALWAYS put the numbers the way the question asks. 

It says wat is the ratio of cheese pizzas to pepperoni pizzas sold each week, So we need to put the amount of cheese pizzas 1st, then the amount of pepperoni pizzas. 

45:20

45 to 20

 45 
------
 20 

Now we will SIMPLIFY. 

45 ÷ 5 = 9

20 ÷ 5 = 4

So, our new ratio would be C. 9:4.

Hope I helped ya!!
