Answer:

297 is the surface area

Step-by-step explanation:

Ok this problem is very simple.

First lets define some equations.

Area of a triangle: A = 1/2BH

A = Area   B = Base   H = Height

This equation works for right triangles only.

(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).

Area of a square: A = BH

Surface area equals all the areas of each side added together.

First lets find the area of one of the triangles.

We know 11 is the base and 8 is the height but the triangle isn't a right triangle.

To make it a right triangle divide the base by 2 so 11/2.

You will get 5.5.

Now find the area!

A = 1/2BH

A = 1/2(5.5)(8)

A = 1/2(44)

A = 22

So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).

22(2)=A

44=A

44 is the area of one side of the pyramid but there are 3 other sides (not including the base).

So just do:

44+44+44+44 = A

176 = A

Surface area for the triangles is 176!

Now we must find the area of the square.

A = BH

A = 11(11)

A = 121

Total surface area is all the areas added together so it's:

121+176=A

Answer:

Option C

Step-by-step explanation:

C: He has $30 on Monday

He deposits $30 on Friday

Amount left= 0

D won't be the answer because

Diver descends 25 feet

She then descends another 25 feet

Total length descended= 25+25= 50 feet

Answer:

C

Step-by-step explanation:

Withdrawal means minus 30 dollars, so right now she is -30 dollars. But depositing is positive, so 30 + (-30) is 0.

Answer:

change in y /change in y to get the gradient . therefore (6--6)=12  and (2--4)=6 thus 12/6=2 that the gradient.

Step-by-step explanation:

form the equation ion form of y=mx+c

and thus the equation y= 2x+c

if you take one point coordinate  such as (2,6)

such that y=6 and x=2 thus the equation will be

6=2*2+C

6=4+C

C=6-4=2

therefore  answer is  

Y=2X+2

Answer:

Y=2X+2

Step-by-step explanation:

1000+2000 = 3000

3000+4000 = 7000

5000+600+70 = 5670

3000 + 5670 = 8670

8670 + 7000 = 15,670

80+9+69+12+35,574= 35744

35744 + 15,670 = 51414

Answer:

1000+2000+3000+4000+5000+600+70+80+9+69+12+35,574= 51,414

[tex]r=2p+22[/tex]

Step-by-step explanation:

[tex]4(p+8)=2(r-6)\\4p+32=2r-12\\4p+32+12=2r\\4p+44=2r\\\frac{4p+44}{2} =\frac{2r}{2} \\2p+22=r[/tex]

Hope this helps you

Let me know if you have any other questions :-)

The equation equivalent to 4(p + 8) = 2(r – 6) when solved for r is

r = 2p + 22.

To solve for r in the equation 4(p + 8) = 2(r – 6), follow these steps:

1. Distribute the numbers: Distribute the numbers on both sides of the equation.

  [tex]\[4 \cdot p + 4 \cdot 8 = 2 \cdot r - 2 \cdot 6\][/tex]

2. Simplify: Perform the calculations on each side of the equation.

 [tex]\[4p + 32 = 2r - 12\][/tex]

3. Isolate r terms: Move the terms containing r to one side of the equation by adding 12 to both sides.

 [tex]\[4p + 32 + 12 = 2r\][/tex]

 [tex]\[4p + 44 = 2r\][/tex]

4. Divide by 2: Divide both sides by 2 to solve for r.

  [tex]\[\frac{4p + 44}{2} = r\][/tex]  

[tex]\[2p + 22 = r\][/tex]

Thus, the equation 4(p + 8) = 2(r – 6) when solved for r becomes r = 2p + 22.

Answer:

$3.24

Step-by-step explanation:

First, we subtract the $9 from the $45, so that equals $36

9% of the 36% is added to the final price as tax

36 x 0.09 = 3.24

Answer:

45-9=36

what we could do is first find out how much 1% is, 36÷1=0.36.

so 0.34×9=3.24

the final answer is 3.24

Answer:

Bonnie :

(0,12),(1,16)

Slope = (16 - 12) / (1 - 0) = 4/1 = 4

So Bonnie is adding $ 4 every week to her savings

Bobby :

y = 12x + 4

The slope here is 12.....so he is adding $ 12 every week to his savings

Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week
