Answers

Answer 1
Answer: 405

Steps:
Note, S = Sum

(2 + 3) * 81= S

Starts with the parenthesis.

2 + 3 = 5

5 * 81 = 405
Answer 2
The song means to add something by something which means 2+3 which is that equals to 5. So, 5 times 81 equals is 405 witch means the answer is 405$

A car rents for $280 per week plus $0.15 per mile. Find the rental cost for a three-week trip of 900 miles.

Answers

Answer:

$975

Step-by-step explanation:

The car is rented for 3 weeks

the rent is for a week is $280 so for three weeks it would be

3*28 = $840

now we need to add the per mile price to this

1 mile = $0.15 for 900 miles it would be

900*(0.15) = 135

So the total rental cost is

$840 + $135 = $975

Answers

In a straight line, all angles sum up to 180°

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

[tex]\hookrightarrow \sf x +\dfrac{1}{4} x = 180[/tex]

[tex]\hookrightarrow \sf \dfrac{4x}{4} +\dfrac{1}{4} x = 180[/tex]

[tex]\hookrightarrow \sf \dfrac{4x+x}{4} = 180[/tex]

[tex]\hookrightarrow \sf 4x+x= 180(4)[/tex]

[tex]\hookrightarrow \sf 5x= 720[/tex]

[tex]\sf \hookrightarrow x = 144[/tex]

Answer:

x = 144°

Step-by-step explanation:

Since the larger line is a straight line, ∠1 and ∠2 are a linear pair. A linear pair is such a pair where two angles sum up to 180°.

⇒ ∠A + ∠B = 180°

Substitute the measure of ∠A and ∠B

⇒ x + x/4 = 180°                                                                    [∠A = x; ∠B = x/4]

⇒ 4x/4 + x/4 = 180°                                                           [Rewrote x as 4x/4]

⇒ 5x/4 = 180°

Using cross multiplication

⇒ 5x = 180 × 4 = 720

x = 720/5 = 144°

Find the value of xx, yy, and zz in the parallelogram below..

Answers

Answer:

36, y = 10, and z = -25

Step-by-step explanation:

99 and -3z +6 are same side interior angles, so they sum to 180 degrees.

99 -3z + 6 = 180

-3z = 75

z = -25

Opposite angles of a parallelogram are congruent

2x + 9 = -3x + 6

2x + 9 = 75 + 6

2x = 81 - 9

2x = 72

x = 36

9y + 9 = 99

9y = 90

y = 10

Working together, Bill and Tom painted a fence in 8 hours. Last year, Tom painted the fence by himself. The year before, Bill painted it by himself, but took 12 hours less than Tom took. How long did Bill and Tom take, when each was painting alone?

Answers

Answer:

Tom paints the fence in 24 hours and Bill paints the fence in 12

Step-by-step explanation:

T = 1 fence / x hours

B = 1 fence / x - 12 hours

B + T = 1 fence / 8 hours

( 1 fence / x - 12 hours ) + ( 1 fence / x hours ) = 1 fence / 8 hours

( 1 / x - 12 ) + ( 1 / x ) = 1 / 8

multiply through all the denominators to get:

8x + 8 (x - 12 ) = x( x - 12 )

8x + 8x - 96 = x^2 - 12x

combine like terms to get:

x^2 - 28x + 96 = 0

factor to get:

( x - 4 ) ( x - 24 ) = 0

x = 4, 24

4 won't work, because that would mean Bill would take a negative amount of time to paint the fence by himself, so that means

Tom paints the fence in 24 hours and Bill paints the fence in 12

has been decreasing by 3 people per
week. In how many weeks will the number of people working out in the aerobics classes be double the number of people
attending the cycling classes?

Answers

Step-by-step explanation:

mx + b = y

 

2x + 96 = y

-3x + 80 = z

 

What we want is y to be twice z, or y = 2z

If we're going to make 2z, then that means its equation needs to be doubled as well:

2x + 96 = 2(-3x + 80)

2x + 96 = -6x + 160

8x = 64

x = 8

 

Now to check our answer:

2 * 8 + 96

16 + 96 = 112

 

-3 * 8 + 80

-24 + 80 = 56

56 * 2 = 112

Given:

The difference between 7 and the sum of 1.0006 and 4.06.

To find:

The mathematical expression for given statement and it value.

Solution:

Sum of 1.0006 and 4.06 = [tex](1.0006+4.06)[/tex]

The expression for the difference between 7 and the sum of 1.0006 and 4.06 is

[tex]7-(1.0006+4.06)[/tex]

On simplification, we get

[tex]7-(1.0006+4.06)=7-5.0606[/tex]

[tex]7-(1.0006+4.06)=1.9394[/tex]

Therefore, the difference between 7 and the sum of 1.0006 and 4.06 is 1.9394.

A manufacturer makes chocolate squares that have a target weight of 8 g.

They calculate the sample mean of the 30 squares to be 8.3 g. Suppose the population standard deviation is 0.87 g and the true weight is 8.5 g. At the 5% level of significance, calculate the power for the test. For full credit, include all steps as described in class.

Answers

Using the normal distribution and the central limit theorem, it is found that the power of the test is of 0.9992 = 99.92%.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem:

The mean is [tex]\mu = 8.5[/tex].The standard deviation is [tex]\sigma = 0.87[/tex].A sample of 30 is taken, hence [tex]n = 30, s = \frac{0.87}{\sqrt{30}} = 0.1588[/tex].

The power of the test is given by the probability of a sample mean above 8, which is 1 subtracted by the p-value of Z when X = 8, so:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{8 - 8.5}{0.1588}[/tex]

[tex]Z = -3.15[/tex]

[tex]Z = -3.15[/tex] has a p-value of 0.0008.

1 - 0.0008 = 0.9992.

The power of the test is of 0.9992 = 99.92%.

Find the area can i get the answer ASAP pls......................

Answers

For the problem on the left, the best way to solve is by splitting the shape into two. The smaller square at the top, and the larger rectangle at the bottom. To find the area of the top of the square you multiply base times height. In this case, you do 36*36, to get 1296. For the larger rectangle, you also do base times height, and calculate 60*36, to get 2160. The final step is to add 2160 to 1296. After adding, you should get the sum of 3456. Add the unit, and since we’re finding area, add squares. The answer is 3456 yards squared.

For the second problem, we can notice that the shape is a trapezoid. The way we find the area of a trapezoid is by taking the average of the bottom length and the top length, and multiply it by the height. The first step is to do 16+8 to get 24. Next, you need to divide 24 by 2 since you’re finding the average of the two numbers. Finally, to finish multiply the height by 12. In this case you do 16*12, to get 192 feet squared.



Answer to A: 3456 Yards Squared
Answer to B: 192 Feet Squared

Step-by-step explanation:

The second solution for the system of equations is (5, 90).

What are Linear Equations?

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given the system of equations,

y - 10 = 11x + x² and

y - 12x = 30

Consider second equation.

y - 12x = 30

⇒ y = 30 + 12x

Substitute y = 30 + 12x in the equation y - 10 = 11x + x², we get,

(30 + 12x) - 10 = 11x + x²

12x + 20 = 11x + x²

12x - 11x - x² + 20 = 0

-x² + x + 20 = 0

x² - x - 20 = 0

Discriminant = [tex]\sqrt{(-1)^{2} -(4*1*-20)}[/tex] = √(1 + 80) = √81 = ±9

x = (1 + 9)/2 and x = (1 - 9) / 2

x = 5 and x = -4

The solution x = -4 and y = -18 is given.

Other solution is,

x = 5

y = 30 + 12x = 30 + 60 = 90

Hence the second solution is (5, 90).
