What is the surface area of the square pyramid?

Answer:

I think it c

im sorry if im wrong  

Answer:

B. 150 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(Length) + 2(Width)

Here, we are given the perimeter and width and we want to find the length

We can do so by plugging in what we are given into the perimeter formula and solving for length.

Perimeter = 2(Length) + 2(Width)

Perimeter = 450 and Width = 75

450 = 2(Length) + 2(75)

We now solve for length

==> simplify multiplication 2(75) = 150

450 = 2(Length) + 150

==> subtract 150 from both sides

300 = 2(Length)

==> divide both sides by 2

150 = Length

And we are done!

The answer is B 150ft

Lets solve for x (x being what time jake will leave)

First, what do we know?

  We know..

So jake should leave around 1:00pm-1:30pm

2:30-1:30=1:00

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

Hope this helps! :)

Answer: The volume is 30

Step-by-step explanation: This is the answer because you multiply the numbers and you get 30FT.

The volume of the prism shaped fish tank is: 408 in.³.

Volume of prism = base area × height of prism.

The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.

Thus:

Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).

Given:

Therefore:

Base area = (7 × 6) + 1/2(3 × 6)

Base area = 51 in.²

Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

Step-by-step explanation:

I'm not sure what you mean by those steps mean but here is how I would answer using the elimination method:

3x - 12y = 5

minus (each term separately: 3x - 3x, -12y - -y, and 5 - 9)

3x - y = 9

This eliminates the 3x and = -11y = -4

You can then simplify from there and get y = 4/11

5

Step-by-step explanation:

[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]

Answer:

H=5

Step-by-step explanation:

Simplifying the equation

We multiply 2(3H) =6H, so the equation is now 12-6H=-18

Isolating the Variables

Then, we subtract 12 from both sides, giving us -6H = -30

Finding H

Finally, we divide both sides by -6, so H= 5

45-1=44

Answer=44

Hey there!

Let's solve this equation for N.

First, let's work out 36+9:

45

45-N=1

subtract 45 from both sides:

-N=1-45

-N=-44

Divide both sides by -1:

N=44 (Option B)

Answer:

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

Answer: 3/52 (~5.77%)

What we know:

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

Probability of a diamond  face card

Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)
