Answer:

the surface area of A is greater than the surface area of B

Step-by-step explanation:

A surface area: 112

B surface area: 104

A area: 60

B area: 60

Answer:

The surface area of A is greater than the surface area of B

Step-by-step explanation:

Volume = L x W x H

A= 3 x 2 x 10

= 60m^3

B = 2 x 6 x 5

= 60m^3

Surface Area = 2(l x w) + 2(l x h) + 2(w x h)

A = 2(3 x 2) + 2(3 x 10) + 2(2 x 10)

= 2x6 + 2x30 + 2x20

= 12 + 60 + 40

= 112m^2

B = 2(l x w) + 2(l x h) + 2(w x h)

= 2(2 x 6) + 2(2 x 5) + 2(6 x 5)

= 2x12 + 2x10 + 2x30

= 24 + 20 + 60

= 104m^2

Step-by-step explanation:

10,000(1+0.05)^5

Answer:

1). Mean: 14.2

  Median: 13.5

Step-by-step explanation:

To calculate the mean, sum all values and divide by the number of values:

(13+16+14+17+13+12) / 6 ≈ 14.2

To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:

12,13,13,14,16,17

The median is (13+14)/2 = 13.5.

Using this explanation you should be able to find the rest.

Answer:

B

Step-by-step explanation:

175 is the yearly cost which is the constant

The cost is related to the miles so that’s why they’re multiplied together

The total amount of reimbursement the company offers will be C = 0.45x + 175. Then the correct option is B.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Joseph's company offers a reimbursement package of $0.45 per mile plus $175 a year for maintenance.

Let 'x' be the number of miles and 'C' be the number total amount. Then the equation of the line is given as,

C = 0.45x + 175

The total amount of reimbursement the company offers will be C = 0.45x + 175. Then the correct option is B.

Answer:

28.8 or 28 8/10

Step-by-step explanation:

A percentage is out of 100. We have to convert 8 3/4 into a percentage. 8 3/4 can also be written as an improper fraction 35/4. Now we have to make the denominator 100. We already knoe that 4 multiplied by 25 equals 100, then we do the same to the numerator. 35 multiplied by 25 gets us to 125. Now we got 125/100. Now since we converted the fracrion into a percentage, now what we do is divide 36 by 125% and that will get you to 28.8 or 28 8/10.

To double check your answer, you can multiply 28.8 by 125% and you will get 36.

Answer:

88

Step-by-step explanation:

you do 120-32

Answer:

x = 58 degrees

Step-by-step explanation:

angle x and the 32 degree angle add up to 90 degrees.

so 90 - 32 = 58 degrees

Answer:

Step-by-step explanation:

We have been given a table that represents the altitude of an airplane with passing minutes.

Since we know that equation of a line in slope-intercept form is: y=mx+b, where, m = Slope of the line and b = y-intercept.

To find the equation of line we will have to the slope of our given line using values from table.

m=\frac{y_2-y_1}{x_2-x_1}, where,

y_2-y_1 = Change in two y-coordinates.

x_2-x_1 = Change in the corresponding x-coordinates.

Upon substituting the coordinates of point (1, 35000) and (2, 31000) we will get our slope as:

m=\frac{31000-35000}{2-1}

m=\frac{-4000}{1}=-4000

Now let us find y-intercept of our given line by substituting m=-4000 and the coordinates of point (1, 35000) in slope intercept form of equation.

31000=-4000*1+b

31000=-4000+b

31000+4000=-4000+4000+b

35000=b

Upon substituting the value of slope and y-intercept the equation of line will be:

a=-4000m+35,000

Therefore, the equation representing the change in altitude a after m minutes is a=-4000m+35,000 and option A is the correct choice.

Answer:

Its b got it correct

The total monthly mortgage payment for the house is $975.63

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

The principle amount is $175000

80% of 175000 is =  = $140000

20% of 175000 is =  = $35000

Emi formula is :

p*r*(1-r)^n/(1-r)^n-1

For 1st part:

p = 140000

r = 4.75/12/100=0.00395

n = 360

Putting values in formula we get

= $729.508

For 2nd part:

p = 35000

r = 7.525/12/100=0.00627

n = 360

Putting values in formula we get

= $245.301

Adding both the monthly payments:

974.809 dollars

This is closest to option A.

So, option A is the answer.

And for 30 years the mortgage payment will be = 351226.80 dollars

Hence, The total monthly mortgage payment for the house is $975.63.

Answer:

Option (A) 3.97.

Step-by-step explanation:

Price for one gallon of gas in gas station 1 = $3.72 (Yesterday)

Price for one gallon of gas in gas station 2 = $3.87 (Yesterday)

Price for one gallon of gas in gas station 3 = $3.78 (Yesterday)

Price for one gallon of gas in gas station 4 = $4.09 (Yesterday)

Price for one gallon of gas in gas station 5 = $3.989 (Yesterday)

Prise raised by each gas station Today = $0.08

Price for one gallon of gas in gas station 1 = $3.72 + $0.08

                                                                      =  $3.80 (Today)

Price for one gallon of gas in gas station 2 = $3.87 + $0.08

                                                                       =  $3.95 (Today)

Price for one gallon of gas in gas station 3 = $3.78 + $0.08

                                                                       =  $3.86 (Today)

Price for one gallon of gas in gas station 4 = $4.09 + $0.08

                                                                       =  $4.17 (Today)

Price for one gallon of gas in gas station 5 = $3.989 + $0.08

                                                                       =  $4.069 (Today)

Mean = Sum of the Terms Number of Terms / Total Number of Terms

          = $3.80 + $3.95 + $3.86 + $4.17 + $4.069 / 5

          = 19.849 / 5

          = 3.9694

          = 3.97 (Approximately)

As we can see that the Option (A) 3.97 correctly matches the answer.

So the correct answer is Option (A) 3.97.

Answer:

Step-by-step explanation:

Given

f(x) = (x - 6)(x + 5)

To find the zeros, let f(x) = 0, that is

(x - 6)(x + 5) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 5 = 0 ⇒ x = - 5

Multiply (2 * 16)

Step-by-step explanation:

Our expression is 13 - 2 * 16 + 2. The two operations used here are addition (+) and multiplication (*).

Remember order of operations PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

We see that multiplication comes before addition, so we multiply 2 by 16 first:

13 - 2 * 16 + 2

13 - 32 + 2

Thus, the answer is multiply.

Answer:

95 is the answer!

The measure of the angle  ∠JHN will be 45°. Then the correct option is B.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Angle ∠MHL and angle ∠JHK are equal because the angles are opposite angles.

∠MHL = ∠JHK

3x + 20 = x + 20 + x + 25

x = 25

Then the measure of the angle  ∠JHN is calculated as,

∠JHN = x + 20

∠JHN = 25 + 20

∠JHN = 45°

The measure of the angle  ∠JHN will be 45°. Then the correct option is B.
