Answer:

$371.25

Step-by-step explanation:

If you want to take away 25%, you would need to find out how much 75% of the current price is. IF you think about it, 75% of the $495 is 25% of 100% of it taken away.

So

0.75 x 495 = 371.25

Answer:

Step-by-step explanation:

-0.71

The r - value -0.71 represents the strongest correlation which is negative correlation.

The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.

For the given situation,

The options has the r - values, we need to check which option represents the strong correlation.

Now., The relationship between two variables is generally considered strong when their r value is larger than 0.7.

A correlation of r = -0.71 suggests a strong, negative association between two variables.

A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

Hence, we can conclude that the r - value option (D) -0.71 represents the strongest correlation which is negative correlation.

Answer:

(c+3b)/8 = a

Step-by-step explanation:

c = 8a -3b

Add 3b to each side

c +3b = 8a-3b+3b

c +3b = 8a

Divide each side by 8

(c+3b)/8 = 8a/8

(c+3b)/8 = a

Answer:

5 miles

Step-by-step explanation:

We have to figure out how many times $1.25 was charged. First, we have to do 2.50 + 1.25 = 3.75 + 1.25 = 5 + 1.25 = 6.25 + 1.25 = 7.5 + 1.25 = 8.75

We charged $1.25 5 times, so this means that it was 5 miles.

Answer:

5 miles

Explanation:

this is because if you subtract 2.50 from 8.75 then you will be left with 6.25. after you do this then you divide 6.25 by 1.25 and this will give you 5 miles.

Sorry the question wasn't really clear??

Answer:

(-13)^2= (15* -11 + -4) = -169

Step-by-step explanation:

Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign

because1 x −1 = −1

(−13)^2=15 x −11 −4

Raise − 13 to the power of 2 .

169=15 x −11 −4

Multiply 15 by −11.

169 = −165 − 4

and finally Subtract 4 from−165.

169 = −169

if its (-13)^2 / (15*-11+-4) as the orginal post did not say divided, the answer would be -1 hope his helps.

Answer:

5 and 6 is slope of two/three

Answer:

1. 35

2. 145

3. 55

4. 90

5. 145

Step-by-step explanation:

1. 35: angle 1 and 2 are a linear pair (meaning it is in one line and adds to 180). Since we know angle 2 is 145, ∠1 = 180 - 145

∠1 = 35

2. 145: ∠7 = ∠2 because they are alternate angles and alternate angles are equal

3. 55: ∠7 = ∠5 + ∠4 because vertically opposite angles are equal. We know that ∠5 = 90, hence ∠4 would equal 145 - 90 = 55

4. ∠5 = 90. It is given

5. 145: ∠9 = ∠2 because they are vertically opposite

Answer:

RS: 26

ST: 40

Step-by-step explanation:

RS + ST = RT

3x - 16 + 4x - 8 = 60

3x + 4x - 16 - 8 = 60

7x - 24 + 24 = 60 + 24

7x = 84

7x / 7 = 84 / 7

x = 12

The value on her gift card decreased by how many dollars.

Solution :

Decrease in dollar is given by :

[tex]D =\text{ rent a tiller for 3 days+ price of rake}\\\\D= \$( 48\times 3 + 5)\\\\D = \$149[/tex]

Therefore, the value on her gift card decreased by 149 dollars.

Hence, this is the required solution.

Answer: 96 in2

Step-by-step explanation: This is because u have to mutiple the two bases and the lateral sides to get your area

The surface area of the cube, in inches² is 96in²

The formula for calculating the surface area of a cube is expressed as:

S = 6L²

L is the side length of the cube

Given that L = 4in. Substitute the given parameter into the formula:

S = 6(4)²

S = 6(16)

S = 96in²

Hence the surface area of the cube, in inches² is 96in²

Answer:

Hi there!

Your answer is:

She worked for 3 Hours on Monday.

Step-by-step explanation:

7.5$ per hour

7.5+2$ per hour on Sundays.

In August:

Sunday, Monday, Wednesday.

# of hours for Monday =Wednesday

Sunday= 4 hrs (which would mean 9.5$ * 4)

Monday and Wednesday will be modeled by X

X + 38$ (earned sunday)= 83$

-38

X= 45$

Since X represents BOTH monday and wednesday, divide by 2

45/2 = 22.5$

CHECK YOUR WORK

22.5$ (monday) + 22.5$ (wednesday) + 38$ (sunday)= 83???

45=38=83???

83=83 YES

Now, to determine how many hours that is, we divide the earned wages by the wage per hour.

22.5 / 7.5 = 3 HOURS

CHECK YOUR WORK

3 hours * 7.5 per hour = 22.5???

22.5 = 22.5 YES

Hope this helps

If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of  hours that Laurie work on Monday will be: 3 hours

$7.5= 1 hour  Other days

$9.50 or ($7.50+$2.00) = 1 hour Sunday

Let Sunday= 4×$9.50 =$38

Let Monday= x × $7.5=$7.5x

Let Wednesday= x × $7.5=$7.5x

Let Total earning=$83

Let x represent the number of  hours

Hence:

First step  is to formulate

7.5x+7.5x+38=83

Second step is to calculate how many hours did Laurie work on Monday

x =83-38÷ 7.5+7.5

x=83-38÷15

x=45÷15

x=3 hours

Inconclusion If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of  hours that Laurie work on Monday will be: 3 hours
