Answer:

see explanation

Step-by-step explanation:

Using the exact values of the trigonometric ratios

sin60° = $\frac{\sqrt{3} }{2}$ , cos60° = $\frac{1}{2}$

sin45° = cos45° = $\frac{1}{\sqrt{2} }$

Using the sine ratio on the right triangle on the left

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{a}{4\sqrt{3} }$ = $\frac{\sqrt{3} }{2}$

Cross- multiply

2a = 4 $\sqrt{3}$ × $\sqrt{3}$ = 12 ( divide both sides by 2 )

a = 6

Using the cosine ratio on the same right triangle

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{c}{4\sqrt{3} }$ = $\frac{1}{2}$

Cross- multiply

2c = 4 $\sqrt{3}$ ( divide both sides by 2 )

c = 2 $\sqrt{3}$

------------------------------------------------------------------------------------------

Using the sine/cosine ratios on the right triangle on the right

sin45° = $\frac{a}{b}$ = $\frac{6}{b}$ = $\frac{1}{\sqrt{2} }$

Cross- multiply

b = 6 $\sqrt{2}$

cos45° = $\frac{d}{b}$ = $\frac{d}{6\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$

Cross- multiply

$\sqrt{2}$ d = 6 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$ )

d = 6

------------------------------------------------------------------------------------------------

a = 6, b = 6 $\sqrt{2}$ , c = 2 $\sqrt{3}$ , d = 6

Cody made deposits of $45, $18, and $27 into his checking account. He then wrote checks for $21 and $93. What would the expressi

Olenka [21]

Answer:

-90 - (-144)

Step-by-step explanation:

Here you go!

Since we're depositing, you'll add the three numbers.

45 + 27 + 18 = $90

Cody deposits 90 dollars in total.

If you write checks, the numbers go down. So you'll add them, and then subtract that by the 90 dollars Cody deposits.

You'll end up with:

45 + 27 + 18 - (21 + 93)

This can simplify to..

90 - (21 + 93)

But wait! Let's add what's in the parenthesis!

93 + 21 = 144

90 - 144 = t

t = -54

Solving this equation will give you: -54

But the simple way is -90 - (-144)

1. A local pizzeria sold 70 pizzas yesterday.

just olya [345]

Answer:

1. 91 = 70*1.30

2a. 195= 150*1.30

2b. 210 = 150*1.40

3a. 56.70 = 156* .30

3b. 132.30 = 156-56.70

3c. 17.20 = 132.30 *0.13

3d. 149.50 = 132.30+17.20

3e. You do not have enough money, because you need $9.50 more.
