When Emily arrives from school she spent a minute eating a snack then she spent 15 playing with her dog and 32 doing her chores

Answers

The question is incomplete:

When Emily arrived home from school she spent a minutes eating a snack. Then, she spent 15 minutes playing with her dog and 32 doing her chores . Finally, Emily spent 45 minutes finishing her homework. How long had Emily been home when she finished?

Answer:

Emily had been home for 1 hour and 33 minutes.

Step-by-step explanation:

In order to find the answer, first you have to add up the time she spent in each activity to find the amount of minutes she had been at home when she finished:

1+15+32+45=93

Now, you can express the 93 minutes in hours considering that one hour has 60 minutes. According to this, Emily had been home for 1 hour and 33 minutes (93-60=33).

Solve the equation 5(x+6)+11=25−3x

Answers

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(x+6)+11=25−3x

Step 1: Simplify both sides of the equation.

5(x+6)+11=25−3x

(5)(x)+(5)(6)+11=25+−3x(Distribute)

5x+30+11=25+−3x

(5x)+(30+11)=−3x+25(Combine Like Terms)

5x+41=−3x+25

5x+41=−3x+25

Step 2: Add 3x to both sides.

5x+41+3x=−3x+25+3x

8x+41=25

Step 3: Subtract 41 from both sides.

8x+41−41=25−41

8x=−16

Step 4: Divide both sides by 8.

8x

8

=

Answers

Answer:

its independent and changes by constant factor per year

In the ranger's function, time is the independent variable, and the total number of deer in the park is the dependent variable.

Given data:

A park ranger recorded the number of deer living in a state park for several years and developed the function p ( t ) = 80 ( 1.2 )^t to model the total number of deer in the park "t" years after she began recording the data.

The total number of deer in the park is represented by "p(t)," which is the output of the function. As the value of "t" increases, the function calculates the total number of deer in the park based on the initial value of 80 and the growth rate of 1.2.

Hence, the time is the independent variable and number of deer is the dependent variable.

Answers

Answer:

p = 1

Step-by-step explanation:

Find P

4 - 5(p + 3/5) = -4

4 - 5p -15/5 = -4

4 - 5p - 3 = -4

-5p + 1 = -4

-5p = -4 - 1

-5p = -5

p = -5/-5

p = 1

Check:

4 - 5(p + 3/5) = -4

4 - 5(1 + 3/5) = -4

4 - 5 - 15/5 = -4

4 - 5 - 3 = -4

The length of a rectangle is one inch less than three times its width. If the perimeter of the rectangle is 118 inches, find the dimensions of the rectangle.

Answers

We can set up the width a X and, from the description the length would be 3X-1. The perimeter of a rectangle is determined by 2XL + 2Xw. Plugging into the equation 2(3X-1) + 2(X) = 118. Next distribute to get 6X-2 + 2X = 118. Combine like terms to get 8X = 120. Divide by 8 to get X = 15. The width is 15. The length is 3(15)-1 or 44. 88 +30 = 118

E.1d+0.015d
F.1d+0.15d
G.1.015d
H.1.15d

Answers

Answer:

E. 1d+0.015d

G. 1.015d

Step-by-step explanation:

A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.
