Hey,I don’t think this is the whole question
Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.
The formula for the area of a rectangle is...
Area = length x width
A = L x W
What we know so far...
Area is 590 cm^2
length is 12 cm
width is unknown
Plug all of these into the equation for area of a rectangle:
590 = 12 * w
or
590 = 12w
Letter A is the correct answer
Hope this helped!

Step-by-step explanation:
<u>Properties used</u>
- logₐ a = 1
- log aᵇ = b log a
- log ab = log a + log b
See the steps below
- - log (4*10⁻³) =
- - (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- - (0.6 - 3*log 10) =
- - (0.6 - 3*1) =
- - (0.6 - 3) =
- - (- 2.4) =
- 2.4
Answer:
$27.90
Step-by-step explanation:
Step 1: Find how much 4 large necklaces will cost
$5.70 * 4 = $22.80
Step 2: Add the cost of 4 large necklaces to the price of 1 small necklace
$22.80 + $5.10 = $27.90
