Answer:
It will cost $21.25
Step-by-step explanation:
We can use ratios to solve
8.50 x
-------- = -----------
100 kg 250 kg
Using cross products
8.50 * 250 = 100 x
Divide each side by 100
8.50 * 250/100 = x
21.25 = x
It will cost $21.25

Pls Help Me Find The Area!!
Answer:
A = 32 cm²
Step-by-step explanation:
the area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the height )
here b = 8 and h = 4 , then
A = 8 × 4 = 32 cm²
Boyce invested an average of $450 per month since age 34 in various securities for his retirement savings. His investments averaged a 4% annual rate of return until he retired at age 63. Given the same monthly investment and rate of return, how much more would Boyce have in his retirement savings had he started investing at age 20? Assume monthly compounding.
a $113,320. 00
b $321,946. 93
c $78,624. 00
d $224,749. 27
If Boyce had started investing when he was 20 the amount he would have more than he does in his retirement savings would be b. $321,946.93.
How much more would Boyce have?First convert the interest to a monthly rate:
= 4% / 12 months
= 1 / 3 %
Period:
= (63 - 34) x 12 months a year
= 348 months
Amount saved:
= Amount x ( (1 + rate) ^ number of periods - 1) / rate
= 450 x ( (1 + 1/3%)³⁴⁸ - 1 ) / 1/3%
= $294,811.07
If he started saving at 20, the number of periods would be:
= (63 - 20) x 12
= 516 months
Amount saved:
= 450 x ( (1 + 1/3%)⁵¹⁶ - 1 ) / 1/3%
= $616,758
The difference is:
= 616,758 - 294,811.07
= $321,946.93

Find the slope of the line that is parallel and perpendicular to the following equation.
-4x - 4y = -2
Answer:
Slope of the line that is parallel: -1
Slope of the line that is perpendicular: 1
Step-by-step explanation:
For the parallel line:
Rewrite your equation to slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)-4x - 4y = -2 <== add 4x to both sides
+4x +4x
-4y = 4x - 2 <== divide both sides by -4
/-4 /-4
y = -x + 1/2
The slope of the line that is parallel to this line is -1 (invisible 1 in front of x).
For the perpendicular line:
*Perpendicular lines have negative reciprocals*
Steps:
1. Take your original slope (-1)
2. Flip it (-1/1)
3. Change the sign (1)
For a slope of -1, the reciprocal would be: 1
Hope this helps!
Answer:
Parallel line:
-1
Perpendicular line:
1
Step-by-step explanation:
Let's simplify first!
-4x-4y=-2
-4x=-2+4y
4y=-4x+2
y=-x+0.5
For a parallel line, the slope should be the same
Therefore...
Slope=1
For a perpendicular line, the slope should be the negative reciprocal of the original.
Therefore...
Slope=-(-[tex]\frac{1}{1}[/tex])
=1

Suppose the graph represents the plans for a fence that Tara is
building for a new city dog park. Each unit on the graph represents
12 yards. After studying the plans, Tara decides to build a fence that
encloses a smaller area. If Tara dilates Rectangle ABCD by a scale
factor of 0.75, and fencing costs $6.39 per yard, how much will she
spend on fencing?
The scale factor of 0.75 would ensure that the new fence has a smaller area
The total cost of fencing the smaller area is $1610.28
How to determine the fencing cost?From the complete question, we have the following parameters:
Number of units on the smaller area, k = 12Scale factor = 0.75Unit cost = $6.39 per yardPerimeter, P = 28 yardsStart by calculating the perimeter of the smaller area using:
Smaller Area = Perimeter * Scale factor * k
Where k represents the number of units on the smaller area
So, we have:
Smaller Area = 28 yards * 0.75 * 12
Evaluate the product
Smaller Area = 252 yards
The total cost is then calculated as:
Total cost = Unit cost * Smaller Area
This gives
Total cost = 6.39 * 252
Total cost = $1610.28
Hence, the total cost of fencing is $1610.28

C. Sarah
(Will mark brainliest and pls fast)
Answer:
C:) Sarah
Step-by-step explanation:
Sarah paid $3.84 for 32 ounces of carrots.
32 ounces = $3.84
1 ounce = x
Cross Multiply
x = $3.84/32
x = $0.12
For Sue
Sue paid $5.20 for 40 ounces of carrots.
40 ounces = $5.20
1 ounce = x
Cross Multiply
x = $5.20/40
x = $0.13
Who paid less per ounce?
Sarah paid less per ounce
