Answer:

cos(55) = 11/x

Step-by-step explanation:

We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.

C

Step-by-step explanation:

Slope of a line that goes trough the points (x1=9, y1=1) and (x2=17, y2=2)

m= (y2-y1)/(x2-x1) = (2-1) / (17-9) = 1/8

A cosmetics company makes three batches of a nail polish color called Purple Dusk using the recipe shown.

Ivanshal [37]

Answer:

Batch 1:- Red 2 ounces Blue 1 1/2 ounces

Batch 2:- Red 3 White 3 3/4 ounces.

Batch 3:- White 4 1/6 Blue 2 1/2 ounces.

Step-by-step explanation:

Batch 1

Amount of the white paint = 5/12 of the batch = 2 1/2 or 5/2 ounces.

5/12 is equivalent to 5/2 ounces of white paint.

1/12 ......................... 5/2 / 5 = 5/10 = 1/2 ounce.

Red paint.

!/3 of the product contains red paint which is 4/12 so this is 4 times 1/12 = 4 * 1/2 ounce = 2 ounces of red paint.

Blue paint.

Similarly to the above amount of blue paint = 1/4 =3/12

= 3 * 1/2 = 1 1/2 ounces of blue paint.

Batch 2.

We can calculate the missing quantities in a similar way to Batch 1.

Blue Paint = 3/12 of the product = 2 1/4 ( = 9/4) ounces so

1 /12 =

9/4 * 1/3 = 9/12 = 3/4 ounce

Red Paint:- 1/12 is equivalent to 3/4 ounce so

Amount of red paint = 4 * 3/4 = 3 ounces (answer)

White paint = 5 * 3/4 = 15/4 = 3 3/4 ounces (answer)

Batch 3.

Red paint = 3 1/3 ounces is equivalent to 4/12 of the product.

So 1/12 = 10/3 / 4 = 10/12 = 5/6 ounces.

White paint = 5/6 * 5 = 4 1/6 ounces.

Blue paint = 5/6 * 3 = 15/6 = 2 1/2 ounces.

You are opening a savings account with $500 that you have saved. The bank offers 3.2% interest, compounded yearly. How much mone

Nuetrik [128]

Answer:

You will have $623.3441462 in your account after 7 years

Step-by-step explanation:

The formula of the compounded interest is A = P $(1+\frac{r}{n})^{nt}$ , where

A is the new value

P is the initial value

r is the rate in decimal

n is the number of periods

t is the time in years

∵ You are opening a savings account with $500

∴ P = 500

∵ The bank offers 3.2% interest, compounded yearly

∴ r = 3.2% ⇒ divide it by 100 to change it to decimal

∴ r = 3.2 ÷ 100 = 0.032

∵ The interest is compounded yearly

∴ n = 1

∵ The time is 7 years

∴ t = 7

→ Substitute these values in the rule above to find A

∵ A = 500 $(1+\frac{0.032}{1})^{1(7)}$

∴ A = 500 $(1.032)^{7}$

∴ A = 623.3441462

∴ You will have $623.3441462 in your account after 7 years
