The length of the base of a square pyramid is 30cm. The height of the pyramid is 45cm. What is the volume of the pyramid in cubic cm?

Answer:

5 units^2

Step-by-step explanation:

Area of a triangle =

[tex] \frac{bh}{2} [/tex]

plugging in:

[tex] \frac{5 \times 2}{2} [/tex]

[tex] \frac{10}{2} [/tex]

[tex]5[/tex]

Answer:

A=1/2(b)(h)

H= 2 units

b= 5

A= 10×1/2 = 5 units^2

Answer:

Answer:

3

Step-by-step explanation:

Answer:

Number 3

Step-by-step explanation:

-6( [tex]\frac{-2}{3}[/tex] + 2x) [distribute -6 to  [tex]\frac{-2}{3}[/tex] and 2x]

= (-6 ×  [tex]\frac{-2}{3}[/tex]) + (-6 × 2x)

= (-6 ×  [tex]\frac{-1}{3}[/tex] × 2) + (-12x)

= (2 × 2) - 12x

= 4 - 12x

Answer:

117

Step-by-step explanation:

180-101 = 79

180-(79+38)

180-117

63

180-63=117

Step-by-step explanation:

Answer + Explanation:

First, find what the sum of the interior angles must be. You can use the formula 180(n - 2) where n is the number of sides to find this.

n = 5, so 180( 5 - 2) = 180 * 3 = 540 degrees.

Then, you can add up all the interior angles of the pentagon and it will add to 540. This means that:

2x + x + 2x + 90 + 90 = 540

5x + 180 = 540

5x = 360

x = 72

Then you can go through and find the measure of each angle:

S = 90 degrees (given)

T = 2x = 2 * 72 = 144 degrees

U = x = 72 degrees

V = 2x = 72 * 2 = 144 degrees

W = 90 degrees (given)

Answer:

Step-by-step explanation:

The Smith family went out to dinner . The price of the meal was $ 29.85 .

The sales tax was 6 % of the price of the meal .

LEts find sales tax amount sales tax amount = price of meal *

sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791

Price of the mean with sales tax = 29.85 + 1.791 = 31.641

The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15

Tip amount = 31.641 * 0.15 = 4.74615

Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715

the Smith family pay for the meal = $ 36.39

Answer:

its B and E i just did the question and got it right

Answer:

B and D

Step-by-step explanation:

Answer:

This price was 27% less than the original price...

this means that the price Scott paid was 73% of the original price.

(0.73) * (original price) = 511

solving for original price:  original price = $ 700

Answer:

d = 7.2

Step-by-step explanation:

We can cross multiply the equation to get:

6 * 30 = 25 * d

(* is multiplication sign by the way)

180 = 25d

Divide both sides by 25 to get:

d = 7.2

Answer:

x = 104 degrees

y = 76 degrees

z = 104 degrees

quadrilateral have to add up all of their interior angles to 360 degrees.

x and c are  opposite interior angles.  after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.

Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.

Answer:

m∡x = 104°

m∡y = 76°

m∡z = 104°

Step-by-step explanation:

m∡A ≅ m∡C

m∡B ≅ m∡D

to find m∡B:  2(104) + 2y = 360

                       208 + 2y = 360

                       2y = 152

                        y = 76

m∡z:  180° - 76° = 104°

Answer:

1/2

Step-by-step explanation:

there are 13 cards in each type so

heart or diamond would mean either one so 13 +13=26

26/52

1/2

TOTAL NUMBER OF HEART CARDS= 13

TOTAL NUMBER OF DIAMOND CARDS= 13

PROBABILITY OF AN EVENT

= NUMBER OF FAVOURABLE OUTCOMES

TOTAL NUMBER OF POSSIBLE OUTCOMES

Probability of getting a heart card♥=13/52 =1/4

Probability of getting a DIAMOND card♦= 13/52 =1/4

Probability of getting a heart and a diamond card =26/52 =1/2

I hope you got it!!!...right!!

Answer:

y=-3x-1

Step-by-step explanation:

Slope-intercept format:

y = mx+b

m = slope

b = y-intercept

Now we plug it in to get the equation:

y=-3x-1

I hope this helped!

Answer: 39°

Step-by-step explanation:

This is a right triangle, meaning one of the angles is a 90° angle. Angle CBA in this case is the 90° angle. In order to figure out the measure of ABD, you subtract the measure of CBA by the measure of CBD, which is 51°.

90 - 51 = 39

Thus, the measure of ABD is 39°

Answer:

35cm

98°

Step-by-step explanation:

4x+3=6x-13

4x+16=6x

16=2x

8= x

4x+3 = 8*4+3 = 35

9y+17=11y-1

9y+18=11y

18=2y

9=y

9y+17 = 9*9+17= 98°
