Answer:
D. 77 + 8
Step-by-step explanation:
7 x 8 = 56
now try the other problems
A. 6 x 8 = 48
B. 6 x 7 = 42
C. 7 x 7 = 49
D. 77 + 8 = 56
D is the answer
Answer: The height of the palm tree is 21 feet.
Step-by-step explanation:
We can use a ratio to solve this:
Actual height to shadow for both objects. The fraction equivalents must be equal.
6/8 = x/28 . Cross multiply
6(28) = 8x
168 = 8x Divide both sides by 8 (8's "cancel" on the right)
168/8 =8x/8
21 = x . This gives us the tree's height as 21 feet.
<em>Another way to solve this is to use the ratios, but simplify the first fraction</em>
<em>6/8 = 3/4</em>
<em>Then multiply the length of the shadow by 3/4</em>
<em>3/4 × 28 = height</em>
<em>28÷4 = 7 7 × 3 = 21</em>
<em>21 feet= the height of the palm tree.</em>
Answer:
3 quarts and 3 cups
Step-by-step explanation:
4 cups=1 quart
Capacity: 5x4+2=22 cups
Right now 1x4+3=7
22-7=15 cups
12/4 +3
3 quarts and 3 cups more
(x1, y1) = (3,8)
(x2, y2) = (1,0)
Answer:
yes
Step-by-step explanation:
42/54 = 6*7/6*9 = 7/9
7/9 = 42/54
