Answer:
Step-by-step explanation:
RT × TS = PT × TQ
The surface area of the square bottom = L x W = 7 x 7 = 49 cm^2
The area for one of the triangles = 1/2 x base x height = 1/2 x 7 x 9 = 31.5 cm^2
There are 4 triangles, the total area for the triangles = 31.5 x 4 = 126 cm^2
Total area = base + triangles = 49 + 126 = 175 cm^2
Answer:
56 grape
Step-by-step explanation:
160 fruit chews
25% are cherry, 40% are peach.....25 + 40 = 65%....so 65% of the fruit chews are NOT grape....meaning (100 - 65) = 35 % ARE grape.
so 35% of all the fruit chews are grape
35% of 160 = 0.35 * 160 = 56 are grape <===
Axis of symmetry is the x value of the vertex
the x value of the vertex, in form
y=ax^2+bx+c is -b/(2a)
so
y=-5x^2-10x-15
a=-5
b=-10
x value of vertex is -(-10)/(2*-5)=10/-10=-1
x=-1 is axis of symmetry
