What is the surface area of the square-based pyramid?
4.5 cm
4 cm

Answer:

B. 117 cm

Step-by-step explanation:

you just multiply them :)

Answer:

117 cm³

(Answer B)

Step-by-step explanation:

The volume is the product of the base area and the height, that is,

V = 13 cm² * 9 cm = 117 cm³

Answer:

Need to see the line to see where the mistake is

Answer:

103.5714286%

or 103.57

Answer:

112*

Step-by-step explanation:

The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112

We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.

Answer:

Step-by-step explanation:

The sum of the measure of the interior angles in a triangle is 180°

m∠D + m∠E + m∠F = 180°

34°  + m∠E + 117° = 180°

     m∠E = 29°

8 - 2x = -8x + 14

-2x + 8x = 14 - 8

6x = 6 / : 6

x = 1

Answer:

7^3/7(75)

Step-by-step explanation:

This is this simplified answer. If you don't understand anything please let me know

Answer:

3675

Step-by-step explanation:

Use the order of operations. Just go from left to right. So, 7 times 7 equals 49. Then, 49 times 7 equals 343. Then, divided by 7 equals 49. 49 times 75 equals 3675. I hope this helps.

Step-by-step explanation:

Answer:

1 inch = 8 feets

Step-by-step explanation:

Actual Length = 168 feets

Scale length = 21 inches

168 / 21 = 8

Actual width = 152 feets

Scale width = 19 inches

152 / 19 = 8

Hence, we can conclude that

Scale used :

1 inch = 8 feets

That is 1 inch in drawing equals 8 feets of the actual size

Answer:

y=-38

Step-by-step explanation:

First we have to put the x value in

2(-10)-18=y

-20-18=y

-38=y

Answer:

46 minutes

Step-by-step explanation:

Number of questions = 23

Time taken per question = 2 minutes

The longest time available to finish all questions :

Longest time will be ; if one spends all two minutes on each question ;

Then ;

Longest time = number of question * maximum time per question

Longest time = 23 * 2 = 46 minutes

Answer:

x = 9 (it is seriously not drawn to scale)

Step-by-step explanation:

BC = DC^2 + BD^2 (Pythagorean theorem)

BC = 4^2 + 6^2

BC = 16 + 36

BC = 52^2

BC = 2sqrt13

BC/AB = DC/BD

(2sqrt13)/AB = 4/6

6(2sqrt13) = 4(AB)

12sqrt13 = 4AB

3sqrt13 = AB

AC^2 = AB^2 + BC^2 (Pythagorean Theorem)

AC^2 = (3sqrt13)^2 + (2sqrt13)^2

AC^2 = 117 + 52

AC^2 = 169

AC = 13  

AD + DC = AC

AD + 4= 13

AD = 9

Answer: -1/2

Step-by-step explanation:

You want to find the equation for a line that passes through the points.

We use formula y2-y1/x2-x1

5-3/-2-2 = 2/-4

= -1/2

Answer:

a

Step-by-step explanation:

Answer:

Part A

The interest on the loan is $609.6

Part B

The interest amount on the last month is $12.7

Step-by-step explanation:

Part A

With the add-on interest method, the interest on the loan is added before the monthly payment is determined

The monthly payment, A = (P × I)/n

Where;

A = The amount payed monthly

P = The principal amount borrowed = $2,540

I = The interest on the loan = P × R × T

R = The interest on the loan = 6%

T = The duration of the loan = 4 years

n = The number of monthly payment = 4 × 12 = 48

Plugging in the variables to the simple interest formula, we get;

I = $2,540 × 6/100 × 4 = $609.6

The interest on the loan, I = $609.6

Part B

The monthly payment is therefore;

∴ A = ($2,540 + $609.6)/48 = $65.61[tex]\overline 6[/tex]

The amount payed as interest on the last month, [tex]I_m[/tex], is given as follows;

$65.61[tex]\overline 6[/tex] - $2,540/48 = $12.7

The amount payed as interest on the last month = $12.7

Answer:

Step-by-step explanation: both graphed is D

The graph D represents the solution of the system of the equation.

One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given, the system of equation;

y = -3x - 5  {equation 1}

y = 3x + 1  {equation  2}

Add both of the equation:

2y = -4

y = -2

And x = 1

And the solution set is (1 , -2).

And only D have the solution set (1 , -2)

Therefore, the graph D represents the solution of the system of the equation.

Answer:

m > $380

Step-by-step explanation:

First, the math:

$500-$120= $380.

She still needs $380.

Her $380 still needed is less than m, which gives us the last answer the most logical.

I hope this helped! Have a nice day.
