The perimeter of the new rectangle is 23cm
How to determine the perimeterFormula for perimeter is given by
Perimeter = 2(length + width)
Perimeter = 2( 6 + 4)
Perimeter = 2 × 10
Perimeter = 20cm
If the length and width are enlarged by 1/2, we have
Perimeter = 2( 6 + 4 +1/2)
Perimeter = 2( 10 + 0.5)
Perimeter = 2× 11. 5 = 23cm
Thus, the perimeter of the new rectangle is 23cm

The perimeter of the square is 64 inches. What is the perimeter of the shaded region?
Answer:
54.94 inches
Step-by-step explanation:
First you need to find the radius of the semi-circles within the square.
You find this by dividing the perimeter by 8
64/8 = 8
now use the formula πr^2 to find the area of the semi circle
π8^2 = 201.06
Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region
16*16 = 256
256-201.06 = 54.94

sweets will each child get?
Answer:
16
Step by Step:
Translate this question into algebra.
You should see something as follows:
[tex]8x=132-4[/tex]
4 subtracted from 132 is 128, so the equation will now look like
[tex]8x=128[/tex]
Now solve the equation by dividing both sides by 8
[tex]x=16[/tex]

Beginning inventory: $14,320 Merchandise Purchases: $7,880 Goods available for sale: (a) Ending inventory: $11,250 Cost of goods sold: (b) solve please!
Answer:
$22,200
$10,950
Step-by-step explanation:
Goods available for sale = beginning inventory + Merchandise Purchases
$14,320 + $7,880 = $22,200
Ending inventory = goods available for sale - ending inventory
$22,200 - $11,250 = $10,950
A Right Cylinder has a radius of 3 cm and a height of 5 cm.
a. Find the Surface Area and Volume of the Right Cylinder.
Answer (Show Work):
b. If you wanted more volume in your cylinder, which of these two ideas would give the most Volume:
i. Doubling the radius to 6 cm, while the height remains 5 cm
OR
ii. Tripling the height to 15 inches, while the radius remains 3cm
Answer (Show Work):
Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
i. Doubling the radius to 6 cm, while the height remains 5
Step-by-step explanation:
Given that :
Radius, r = 3cm
Height, h = 5cm
Volume , V of right cylinder :
V = πr²h
V = π * 3² * 5
V = 141.37166
V = 141.37 cm³
Surface Area :
2πr(h + r)
2 * π * 3(3 +5)
18.849555(8)
150.79644
= 150.80 cm²
Volume at r = 6 ; h = 5
V = π * 6² * 5
V = 565.48667 cm³
Volume at r = 3 ; h = 15
V = π * 3² * 15
V = 424.11500 cm³
To increase volume,

Answer:
[tex]y = \frac{1}{3} x-4[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m=\frac{(-2)-(-3)}{(6)-(3)} \\m = \frac{-2+3}{6-3} \\m = \frac{1}{3}[/tex]
Thus, the slope is [tex]\frac{1}{3}[/tex].
2) Next, write the equation of the line using the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex]. (From there, we can convert it to slope-intercept form.) Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{1}{3}[/tex] for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, substitute the x and y values of either one of the given points (it doesn't matter which one, it will equal the same thing) into the formula as well. I chose (3, -3), as shown below. From there, convert the point-slope form of the equation to slope-intercept form by isolating y:
[tex]y-(-3) = \frac{1}{3} (x-3)\\y + 3=\frac{1}{3} x-1\\y = \frac{1}{3} x-4[/tex]

A vision insurance company selects a SRS of 300 clients who wear contact lenses. They randomly assign 200 clients to the experimental group to receive an app that promotes contact lens hygiene. The remaining 100 clients form the control group. Suppose that without the app, 96%, percent of their clients with contact lenses would have healthy eyes for the year, and that with the app, 99%, percent would have healthy eyes.
After a year, the insurance company looks at the difference (Experimental−Control) between the proportions of clients with healthy eyes in each group.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
A
Approximately normal, because we expect 288 healthy and 12 not-healthy in both groups, and all of these counts are at least 10.
B
Approximately normal, because we expect 192 healthy and 20 not-healthy eyes for the experimental group, and 96 and 40 for the control group, and all of these counts are at least 10.
C
Not normal, because we expect fewer than 10 clients with healthy eyes in both groups.
D
Not normal, because we expect fewer than 10 clients with not-healthy eyes in both groups.
Answer:
NO, its D: Not normal, because we expect fewer than 101010 clients with not-healthy eyes in both groups.

jess solved the quadratic equation x^2+2x = 8 but made a mistake. her work is shown below. identify the step(s) in which a mistake was made
Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2
