Answer:
$ 35.96
Step-by-step explanation:
Let x be the cost ( in dollars ) of 4 ounces of the pecans,
So, the ratio of the cost and ounces needed =
Also, the cost of 1 ounces of pecans is $ 8.99,
Thus, the ratio of the cost and ounces needed =
Hence, we can write,
Which is the required proportion,
By cross multiplication,
x = 4 × 8.99 = 35.96
Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
Answer: 14s - 7s/2 = 84
Step-by-step explanation:
Given that s is the length of the unknown side:
Area of the shaded region = 84
Area of rectangle - Area of triangle = 84
Area of rectangle = L * W
= 14 * s
= 14s
Area of triangle = ¹/₂ * base * height
= ¹/₂ * 14 * s/2
= 7s/2
Area of shaded region:
14s - 7s/2 = 84
Solving for s:
14s - 7s/2 = 84
28s - 7s = 168
21s = 168
s = 168/21
s = 8 inches
Answer:
21,000
Step-by-step explanation:
This is more of straightforward multiplication, so I cannot explain much! If you want me to try to do more, then just comment.
(7 * 10 * 5) * (3 * 10 * 2)
= (70 * 5) * (30 * 2)
= (350) * (60)
= 21,000
Thusly, in standard form, the equation given is .
Hope this helps! (:
