Answer:We are asked to evaluate Marlena's solution in solving the expression below: 2x+5 = -10 -x

The first step is to re-write the expression and transpose same terms in the left side while all numbers are transferred to the right side such as shown below:

Step 0: 2x+5 = -10 -x

Step 1: 2x + x = -10 -5

Step 2: 3x = -15

Step 3: x =-15/3

The answer is x=-5.

Answer:

10n^2 + 2n + 16

Step-by-step explanation:

Rectangles have the same length and same width. So we can deduce that the top side is 5n^2 - 1, and the left side is n + 9.

Now all we need to do is add all 4 sides up:

(5n^2 - 1) + (5n^2 - 1) + (n + 9) + (n + 9)

or

2(5n^2 - 1) + 2(n + 9)

= 10n^2 - 2 + 2n + 18

= 10n^2 + 2n + 16

Step-by-step explanation:

An inscribed sphere in a cube will have a diameter equal to the edge length of the cube:

  d = e

Hey there!

3x + (4x+5)° = 180° {sum of co-interior angle 180°}

The total amount accrued, principal plus interest, with compound interest on a principal of $4,000.00 at a rate of 2.48% per year compounded 4 times per year over 1 years is $4,100.13.

Given Data

A = P + I where

P (principal) = $4,000.00

I (interest) = $100.13

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.48/100

r = 0.0248 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 4,000.00(1 + 0.0248/4)^(4)(1)

A = 4,000.00(1 + 0.0062)^(4)

A = $4,100.13

Answer:

452.16 m²

Step-by-step explanation:

Given :-

Radius = 12 m

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 12 x 12

= 3.14 x 144

= 452.16 m²

Solution :-

452.16 m²

Answer:

144

Step-by-step explanation:

A=πr^2

Where:

A

is the Area of the Circle: what we are solving for in this problem.

r

is the Radius of the Circle: 12 meters for this problem

Substituting and calculating

A

gives:

A=π(12)^2m^2

A=π144m^2

A= 144m^2

This circle would have an area of 144 square meters.

Answer/Step-by-step explanation:

Perimeter of a right triangle : 3 units , 5 units, 4 units

Perimeter = 3 + 4 + 5 = 12

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Surfaces of a three-dimensional figure: 5ft, 7 ft, 3 ft

Surfaces area: 2(7*3)+2(7*5)+2(3*5)

= 142 square feet

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Volume of a three-dimensional figure: 4m , 10 m , 3 m

Volume = 10 * 4 * 3 = 120 cubic meter

~Lenvy~

Answer:

Step-by-step explanation:

Perimeter of a triangle = sum of 3 sides

= 3 + 4 + 5

= 12 units

Surfaces of a three-dimensional figure = sum of 3 pairs of surfaces

= 5*7*2 + 7*3*2 + 3*5*2

= 70 + 42 + 30

= 142 square fts

Volume of a three-dimensional figure = length*width*height

= 4*10*3

= 120 m^3

Answer:

  x = -8

Step-by-step explanation:

The sum of arcs of a semicircle is 180°. That means the arc whose measure is -11x+12 has a measure of 180° -80° = 100°.

  -11x +12 = 100

  -11x = 88 . . . . . . subtract 12

  x = -8 . . . . . . . divide by -11

Answer:

56.6 ft

Step-by-step explanation:

→ Perimeter = All sides added together

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

Answer:

56.6

Step-by-step explanation:

Perimeter is just adding all the outer value of an shape

So we add all the answers

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

but there is easier way

5.2 x 2 = 10.4

7.7 x 6 = 46.2

10.4 + 46.2 = 56.6

at the end don't forget to add "ft"

Answer = 56.6 ft

The test that we would use to test the hypothesis that the average speed of cars is greater than the speed limit is: One sample t-test

When we want to find out from the sample if the unknown population mean is different from some specific value, then we can use one sample t-test.

The test statistic is:

[tex]t = \dfrac{\overline{x} - \mu_0}{s/\sqrt{n}}[/tex]

where we have:

For this case, we want to test  the hypothesis that the average speed of cars is greater than the speed limit.

That means we want to know if

unknown population mean (the average speed of cars) > speed limit (45).

symbolically, we want to test if [tex]\mu > 45[/tex] (in miles per hour)

Thus, the test that we would use to test the hypothesis that the average speed of cars is greater than the speed limit is: One sample t-test
