Answer:

x = 19; y = 19√3

Step-by-step explanation:

sin 30° = opp/hyp

sin 30° = x/38

x = 38 × sin 30°

x = 19

cos 30° = adj/hyp

cos 30° = y/38

y = 38 × cos 30°

y = 38 × √3/2

y = 19√3

Answer:

387 contains 80 and 8 x 10 = 80

Multiply both sides by 2:

Divide both sides by 11in :

A triangle has an area of 66 in². If the base is 11 inches, what is the height?

The height of the triangle is 12 inches.

As per the provided information in the given problem, we know that the area of a triangle is given by 66 inches². The base of the triangle is given by 11 inches. In this problem, we are tasked to find the height of the triangle.

To do this, we will use the formula below:

[tex]\Large\begin{aligned}\rm\qquad\dashrightarrow{Area_{(Triangle)} = \dfrac{1}{2}bh}\end{aligned}[/tex]

Where:

Substitute the given values into the formula given earlier and solve for h:

[tex]\Large\begin{aligned}\rm\dashrightarrow{Area_{(Triangle)}}& = \rm{\dfrac{1}{2}bh}\\\rm\dashrightarrow{66\: in^2}& = \rm{0.5(11\: in)(h)} \\\rm\dashrightarrow{66\: in^2}& = \rm{(5.5\: in)(h)} \\\rm\dashrightarrow{\dfrac{66\: in^{\cancel{2}}}{5.5\: \cancel{in}}}& = \rm{\dfrac{(\cancel{5.5\: in})(h)}{\cancel{5.5\: in}}} \\\rm\dashrightarrow{12\: in}& = \rm{h}\end{aligned}[/tex]

[tex]\frac{7\times15}{100}[/tex]

Step-by-step explanation:

Given the following question:

7% of 15

To find the answer we need to use the formula to calculate percentages in which we multiply the percentage by the whole number and then divide that answer by 100, of course rounding to the nearest cent if needed.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7\times15}{100}[/tex]
[tex]7\times15=105[/tex]

7% of 15 is "1.05" which means Regina receives a $1.05 raise.

     "Not independent" means that the situation is dependent. It is not relying on something else, or something else will not change the outcome. Independent means the situation is isolated, it is independent.

A jar contains green marbles and orange marbles. A green marble is selected followed by an orange marble, at random, without replacement.

Not independent

-> Since the marbles are not being replaced, this isn't independent

A coin is flipped three times.

A bag contains nickels and dimes. A nickel is selected followed by a dime, at random, with replacement.

Answer:

10 centimeters = 0.1 meters

Step-by-step explanation:

Question  

How many meters are in 10 centimeters?

There are 100 centimeters in 1 meter.

Therefore, 1 centimeter = 1 ÷ 100 meters

                                       = 0.01 meters

So if 1 centimeter = 0.01 meters

Then 10 centimeters = 0.01 × 10 = 0.1 meters

Answer:

5 inches and 4 inches

Step-by-step explanation:

The perimeter is equal to 2(2x + 1) + 2(x + 2) since there are two sides of the rectangle equal to the expressions given.

Since we also know that the perimeter is 18 inches, we can set that equal to 18.

2(2x + 1) + 2(x + 2) = 18

4x + 2 + 2x + 4 = 18

6x + 6 = 18

6x = 12

x = 2

After plugging 2 back into 2x + 1 and x + 2, you get 5 and 4. Hope this helped!

Answer:

12.5%

Step-by-step explanation:

Divide 1 by . Therefore, the fraction 18 is equivalent to 12.5% .

Answer: First find the volume of the rectangle prism. Do this by multiplying all three dimensions. 412 x 412 x 6 = 1,018,464.

Subtract 1,018,464 from 143.

You should get 1,018,321 mm^3

(Remember that the units are cubed because you multipled 412 mm x 412 mm x 6 mm which is multiplying not only the numbers, but the mm three times as well.)

Step-by-step explanation:

okay, so she rode 3 miles. Keep that aside

Then she had 2 walk the remaining 2 miles

She had to walk all the way home. So say for example instead of riding she walked 3 miles, then she walked that additional 2 miles. So, 5 miles. Then add the two miles she had to walk to his house. so, she walked 7 miles and rode 3 miles. 7-3= 4 miles. I attached a picture that should hopefully explain it better.

Answer:

  $8727

Step-by-step explanation:

The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.

Melanie's investment value is computed using the formula ...

  FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years

  FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)

  FV = $181,721.94

__

Lillian's investment value is computed using the formula ...

  FV = Pe^(rt)

  FV = $63,000·e^(0.07375×15)

  FV = $190,449.05

__

The amount more that Lillian has is ...

  $190,449.05 -181,721.94 = $8,727.11

Lillian has about $8727 more than Melanie.

Answer:

8 quarters and 4 dimes

Step-by-step explanation:

4 quarters = 1 dollars

4 quarters = 1 dollars

4 dimes = 40 cents

2.40$

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

Work Shown:

d = number of dimes

q = number of quarters

1 dime = 10 cents

d dimes = 10d cents

1 quarter = 25 cents

q quarters = 25q cents

d+q = 12 since we have 12 coins total

q = -d+12 after solving for q

10d+25q = total value in cents

10d+25q = 240

10d+25(-d+12) = 240 ... plug in q = -d+12

10d-25d+300 = 240

-15d+300 = 240

-15d = 240-300

-15d = -60

d = -60/(-15)

d = 4

q = -d+12

q = -4+12

q = 8

Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters

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

Check:

4 dimes = 4*10 = 40 cents

8 quarters = 8*25 = 200 cents

(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents

240 cents = 240/100 = $2.40

We have 4+8 = 12 coins total

The answers are confirmed
