Answer: $\frac{7}{10}$

Step-by-step explanation:

2 $\frac{1}{10}$ barrels of almonds to make 3 batches of granola bar.

We need to turn fraction 2 $\frac{1}{10}$ into a mixed number

2 $\frac{1}{10}$ → $\frac{21}{10}$

Now we set up an equation.

$\frac{\frac{21}{10} }{3} =\frac{x}{1}$

Solve for x by cross multiplying and dividing.

$\frac{21}{10}$ ÷ 3 (KCF)

$\frac{21}{10}$ × $\frac{1}{3}$ = $\frac{21}{30}$

Now we simplify the fraction.

$\frac{21}{30}$ → $\frac{7}{10}$

$\frac{7}{10}$ barrels of almonds were used in each batch.

Find the value of x<br> Use sin, cos, or tan

Serhud [2]

<h3>Answer: 16.5</h3>

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

Explanation:

We use cosine to tie together the adjacent and hypotenuse

cos(angle) = adjacent/hypotenuse

cos(38) = x/21

21*cos(38) = x

x = 21*cos(38)

x = 16.5482258257411

x = 16.5

Look at the two patterns below: Pattern A: Starts at 5 and follows the rule "add 6" Pattern B: Starts at 5 and follows the rule

OleMash [197]

Answer:

The first five terms in Pattern A are 5, 11, 17, 23, and 29

Step-by-step explanation:

Pattern A:

5 + 6a

Pattern B:

5 + 3a

Take a = 1 and compare ;

Pattern A:

5 + 6(1) = 11

Pattern B:

5 + 3(1) = 8

A ≠ 2B

B ≠ 1/3A

First 5 terms in pattern A :

Pattern A:

5 + 6(1) = 11

5 + 6(2)= 17

5 + 6(3) = 23

5 + 6(4) = 29

5 + 6(5) = 35

Pattern B cannot have a term 0 as it starts from 5
