The answer is b: 40 miles in 5 hours
solution: simplify both numbers by the gcf
40/5=8
5/5=1
8:1
Answer:
x=-11, y=-5. (-11, -5).
Step-by-step explanation:
2y=2x+12
y=-2-3
-----------------
simplify 2y=2x+12 into y=x+6
y=-5
------------------
-5=x+6
x=-5-6=-11
1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,
A = L*H = 12*6 = 72 cm^2
3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).
Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2
4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.
Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm
Answer: the answer would be D
Step-by-step explanation: in the exponent fraction the root would be 3 because the base of the fraction is thred. Always look at that.
