Answer:
189
Step-by-step explanation:
The pyramid has four triangular faces and a square base.
The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.
The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.
The total surface area is:
A = 4(35) + 49
A = 189
Answer:
D) 2(x + 10)(x - 10)
Step-by-step explanation:
2x^2 - 200
factor out a 2
2(x^2 -100)
both x^2 and 100 are squares so
a^2 – b^2 = (a + b)(a – b)
a=x and b = 10
2(x^2 -100) = 2( x-10 )(x+10)
= 2(x+10) (x-10) the order in which we multiply doesn't matter
The answer is the AREA of a figure is a measurement of the space inside it.
To get your answer first you multiply $84.50 times 20 months which is $1,690, then you multiply $50.50 times 20 months to get 1,010. Then you subtract 1,690, and 1,010, to get 680. Now you divide 680 by 4 to get 170 which is 1/4 of what is left in her account. So Jasmine spent a total of $170 to go to music camp.
