Answer:

[tex]x = 21 \sin(38 \degree) \\ x = 12.93[/tex]

The more accurate value is roughly x = 16.5482258257411

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

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(38) = x/21

21*cos(38) = x

x = 21*cos(38)

x = 16.5482258257411 which is approximate

x = 17

I'm rounding to the nearest whole number since the other side (21) is a whole number. If your teacher instructs you to round otherwise, then follow those instructions of course. Make sure your calculator is in degree mode.

Answer:

Average of 3mph

Step-by-step explanation:

If Sarah goes uphill at 2mph and downhill at 4mph.

Then to find the average you can:

Add 2 plus 4

which equals 6

Then divide the sum of 6 by the number of values given, there are two values (2 and 4)

6 divided by 2 equals 3

So the average is 3mph

Answer:

A) 20%

Step-by-step explanation:

The total votes are:

40 + 70 + 60 + 90 = 260

Rebecca has the highest percent of votes which is 90 votes. To find the %:

90/260 ≈ 34.62%

Amy has the lowest percent of votes which is 40 votes.

40/260 ≈ 15.38%

Finding the difference:

34.62 - 15.38

19.24

So, it's around 20%

Answer:

$13.2

Step-by-step explanation:

Cost of 1 inch = $0.4

Perimeter of painting is same as perimeter of a rectangle since painting is a rectangle

Perimeter = 2(l+b)

L = 10¼

B = 6¼

P = 2(10¼ + 6¼)

P = 2(41/4 + 25/4)

P = 2(10.25 + 6.25)

P = 2(16.5)

P = 33

Total cost of framing

= 0.4 x 33

= $13.2

> x = 32°

Answer:

a). x=18x2

        18x2=36

Don spent 36 dollars.

b). x=36x0.3

        36x0.3=10.8

Brad's sister spent 10 dollars and 80 cents.

c). 36+18=54

1.0-0.13 = 0.87

54x0.87=46.98

54-46.98=7.02

Don and Brad paid 7 dollars and 2 cents in tax.

Answer:

6/8

Step-by-step explanation:

or to simplify it, it would be 3/4

The probability that the spinner will land on green is 6 out of 8 or 75%.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

Number of equal sections on the spinner = 8

Number of sections which are green = 6

Probability can be calculated as the ratio of number of desired outcomes to the total number of outcomes.

Here,

Desired outcome is the spinner landing on green.

Probability = 6/8 = 0.75 = 75%

Hence the probability is 6 out of 8 or 75%.

Answer:

b)

p = d − 2

p = d + 1

Step-by-step explanation:

From the above question:

Interpreting the statement above to form algebraic expressions, we have:

Variable p is 2 less than variable d.

Less than means to subtract in this context

p = d - 2

Variable p is also 1 more than variable d

More than means to add in this context

p = d + 1

Therefore, the pair of equations tha best models the relationship between p and d is Option b :

p = d − 2

p = d + 1

Answer:

this would cause the median price to go down by $5 as well.

Step-by-step explanation:

If every single backpack in the store is on sale, then this would cause the median price to go down by $5 as well. This is because the median price is the middle value in a data set. Therefore, if every backpack value drops by $5 then so does the backpack that has the middle value and is the median price of all the backpacks. This is the only actual effect that this sale will have to the median price of the backpacks.

Given:

Side of a square = x units

The side of square is decreased by 9 units.

To find:

The expression that represents the area of the new square in square units.

Solution:

It is given that, the side of a square is x units and it is decreased by 9 units. So, the side of new square is:

[tex]\text{New side length}=x-9[/tex]

The area of a square is:

[tex]Area=(side)^2[/tex]

So, the area of the new square is:

[tex]Area=(x-9)^2[/tex]

[tex]Area=(x)^2-2(x)(9)+(9)^2[/tex]          [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]Area=x^2-18x+81[/tex]

Therefore, the expression for the area of the new square is either [tex](x-9)^2[/tex] or [tex]x^2-18x+81[/tex], both are equivalent.

Answer:

Width of the box = 18.97 inches

Step-by-step explanation:

Length of the bat = 36 inches.

That means length of the diagonal of the bat (BC) = 36 inches

By applying Pythagoras theorem in right triangle BDC,

BC² = BD² + CD²

BC² = (30)² + w² -------(1)

BY applying Pythagoras theorem in right triangle ABC,

AC² = AB² + BC²

(36)² = 6² + BC²

By substituting the value of BC from equation (1),

(36)² = 6² + (30)² + w²

1296 = 36 + 900 + w²

w² = 1296 - 936

w = √360

w = 18.97 inches

Answer:

$2332.25 per month

Step-by-step explanation:

1) The monthly share of annual expenses can be calculated from the annual expenses. Since there are 12 months in a year, the monthly share of annual expenses is gotten by dividing the annual expenses by the number of months in a year.

2) The monthly share of annual expenses is given by:

Monthly share of annual expenses = Annual expenses / 12 months

Monthly share of annual expenses = $27987 / 12 months = $2332.25 per month

Answer:

Theta = 10n/9 radians.

Step-by-step explanation:

The length is 5n units

Radius is 4.5 units

center angle is, S = r * theta

                         5n = 4.5 * theta

                       Theta = 5n/4.5
