Find the total surface area of the
following square pyramid:
9 cm
10 cm
SA = [?]cm2
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer:
SA = [280] cm 2
Step-by-step explanation:
For Lateral Area the formula is 4(1/2 10 x 9)
But the 1/2 makes it 4(1/2 5 x 9)
Then you multiply 5 x 9 = 45 then multiply 45 by the 4 and get 180
Then for Surface Area you put in (180 + 100) = 280
You get the 100 by multiplying 2 of the base numbers together.

Three cubic feet of seawater weigh 192 pounds.
What is the weight of the seawater in an aquarium that is 4.4 ft long, 2.5 ft wide, and 5.3 ft high?
Answer:
3731.2 pounds
Step-by-step explanation:
Aquarium will hold 4.4 * 2.5 * 5.3 = 58.3 cubic feet of sea water.
For 3 cubic feet of sea water, weight is 192 pounds
For 58.3 cubic feet of sea water,
( 192 * 58.3) / 3 = 11193.6 / 3 = 3731.2 pounds
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
Answer:
52 young calves
Step-by-step explanation:
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
The ration is given as:
adult milking cows to young calves
= 9 : 2
= 234 : x
= 9/2 = 234/x
x = Number of young calves
Cross Multiply
9 × x = 2 × 234
= x = 2 × 234/9
x = 468/9
x = 52
Hence, the number of young calves on the farm is 52.
Write the number 68,127,000,000,000,000 in scientific notation.

Christo graphs AB with endpoints A( -3, -2 ) and B ( -1, -2 ) what are the endpoints of the image after a reflection of AB across the x axis?
1. (-3,2) and (-1,2)
2.(-3.-2) and (-1,-2)
3. (1,-2) and (3,-2)
4. (2,3) and (2,1)
5. none of the above
Answer:
1. (-3,2) and (-1,2)Step-by-step explanation:
Reflection over x-axis results in coordinate change as follows:
(x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to oppositeGiven points:
A(-3, -2) and B(-1, -2)The image of AB will have coordinates:
A'(-3, 2) and B'(-1, 2)Correct choice is 1.
Answer:
(-3,2) and (-1,2)

Separate 185 into two parts so that one part is 31 more than the other part. Find each part.
9514 1404 393
Answer:
108, 77
Step-by-step explanation:
Let x represent the larger part. Then ...
x + (x -31) = 185
2x = 216
x = 108
x -31 = 77
The two parts are 108 and 77.
