Answer:

4,784ft^2

Step-by-step explanation:

Well in this case we will just use the square and triangle area formulas instead of the pyramid surface area formula.

So if the base is a square then the area is 32*32 which is 1,024.

Now for the trangle, the area of a triangle b*h/2.

So b*h is 47*32 which is 1,504.

So 1,504/2 is 752.

So 752 is the area of 1 triangle and we have 4 so 5*752 is 3,760.

So 3,760 + 1,024 is 4,784.

So the total SA if the pyramid is 4,784ft^3.

One week a business sold 40 shirts. White ones cost $4.95, and the printed ones cost 7.95. In al $282 worth of shirts were sold.

Tanya [424]

Answer:

12 white 28 printed

Step-by-step explanation:

x = white y = printed

x + y = 40————(1)

4.95x + 7.95y = 282————(2)

Solve for x using 1st equation

x = 40 - y Plug in for x using 2nd equation

4.95(40 - y) + 7.95y = 282 Solve for y

198 - 4.95y + 7.95y = 282

3y = 84

y = 28 Plug in for y using 1st equation

x + (28) = 40 Solve for x

x = 12

Each problem below gives the endpoints of a segment. Find the coordinates of the midpoints of each segment. A.(5, 2) and (11, 14

kvv77 [185]

The midpoints are (8,3) and (6.5,6).

<u>Step-by-step explanation</u>:

Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)

(x1,y1) = (5,2)

(x2,y2) = (11,4)

Midpoint = ((5+11)/2 , (2+4)/2)

⇒ ((16/2) , (6/2))

⇒ (8,3)

(x1,y1) = (3,8)

(x2,y2) = (10,4)

Midpoint = ((3+10)/2 , (8+4)/2)

⇒ ((13/2) , (12/2))

⇒ (6.5,6)

PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER

masya89 [10]

(2, -4) → x = 2, y = -4

Put the coordinates of the point to the inequality.

y < x - 2 → -4 < 2 - 2 → -4 < 0 TRUE

y ≥ -x -4 → -4 ≥ -2 - 2 → -4 ≥ -4 TRUE

Answer:

$\left\{\begin{array}{ccc}y$

You can check other systems.

(2) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE

(3) y ≤ -x - 4 → -4 ≤ -2 - 4 → -4 ≤ -6 FALSE

(4) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE

I need help can someone help you can get 10 points

Nuetrik [128]

Answer:

Im not sure if i can give you the entire answers, but its quite simple. A straight line=180 degrees, so subtract 112 by 180 and you get lines 1 and 3. Line 2 is just 112 because its just "flipped", so its the same number.

5/6+3/4+2/3 answer please

nlexa [21]

Answer:

2.25

Explanation

2/3 can be made into 4/6 then added to 5/6

Grab 5/6 and add it to 3/4, we do this by making them have the same bottom number (denominator) so we multiply 9/6 (4/6 + 5/6) by 2 (both top and bottom number) so now we have 18/12 + 4/6 so now we can make 4 be 12 by multiplying it by 3, but we need to do that to the top number as well to make it balanced, so now we have 18/12 + 9/12 and we get 27/12 or 2.25.
