Answer:
n = 96
Step-by-step explanation:
[tex]66\frac{2}{3}[/tex] % = [tex]\frac{200}{3}[/tex] %
[tex]\frac{64}{n}[/tex] = [tex]\frac{\frac{200}{3} }{100}[/tex]
[tex]\frac{\frac{200}{3} }{100}[/tex] = [tex]\frac{2}{3}[/tex]
[tex]\frac{64}{n}[/tex] = [tex]\frac{2}{3}[/tex]
2n = 192 ⇒ n = 96
Kevin bought 3 dvds for 45.99 how much would 7 dvds cost?
Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong.
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.
45.99 / 3 = 15.33
15.33 x 7 = 107.31

I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.
(3x + 28) + (5x - 18) + 90° = 180°
Now i can get rid of the parentheses and combine like terms.
3x + 5x + 28 - 18 + 90 = 180
8x + 10 + 90 = 180
8x + 100 = 180
Then i subtract 100 from both sides to isolate x.
8x + 100 - 100 = 180 - 100
8x = 80
Then, i divide both sides by 8 to find x.
8x ÷ 8 = 80 ÷ 8
x = 10

Set up and evaluate the optimization problems. (Enter your answers as comma-separated lists.) Find two positive integers such that their sum is 14, and the sum of their squares is minimized. Find two positive integers such that their sum is 14, and the sum of their squares is maximized.
Answer and Step-by-step explanation:
Let x and y be two positive integers and their sum is 14:
X + y = 14
And the sum of square of this number is:
f = x2 + y2
= x2+ (14 – x)2
Differentiate with respect to x, we get:
F’(x) = [ x2 + (14 – x)2]’ = 0
2x + 2(14-x)(-1) = 0
2x +( 28 – 2x)(-1) = 0
2x – 28 +2x = 0
2x + 2x = 28
4x = 28
X = 7
Hence, y = 14 – x = 14 -7 = 7
Now taking second derivative test:
F”(x) > 0
For x = y = 7,f reaches its maximum value:
(7)2 + (7)2 = 49 + 49
= 98
F at endpoints x Є [ 0, 14]
F(0) = 02 + (14 – 0)2
= 196
F(14) = (14)2 + (14 – 14)2
= 196
Hence the sum of squares of these numbers is minimum when x = y = 7
And maximum when numbers are 0 and 14.

I have a rectangular garden. I usually grow cucumbers in 2/3 of my garden, but I want to take 3/4 of the cucumber section to grow
radishes. After I make this change, how much of my whole garden will
be radishes?
Answer:
[tex]\frac{1}{2}[/tex] of the garden will be radishes.
Step-by-step explanation:
Given a rectangular garden which grows cucumbers in [tex]\frac{2}{3}[/tex] of the garden.
[tex]\frac{3}{4}[/tex] of the cucumber section to grow radishes.
To find:
How much of the whole garden will be radishes?
Solution:
Let the total area of the garden = [tex]x[/tex] sq units
Then as per our assumption, total area to grow cucumbers:
[tex]\frac{2x}{3}[/tex] sq units
Cucumber area to grow radishes = [tex]\frac{3}{4}[/tex] of cucumber area
[tex]= \dfrac{3}{4}\times \dfrac{2x}{3}\\\Rightarrow \dfrac{x}{2}\ sq\ units[/tex]
Fraction of whole garden to grow radishes = Area to grow radishes divided by whole area of garden
[tex]\Rightarrow \dfrac{\frac{x}{2}}{x}\\\\\Rightarrow \bold{\dfrac{1}{2}}[/tex]
Therefore, [tex]\frac{1}{2}[/tex] of the garden will be radishes.

Alligators captured in Florida are found to have a mean length of 2 meters and a standard deviation of 0.35 meters. The lengths of alligators are believed to be approximately normally distributed. What is the approximate length of an alligator at the 67th percentile of alligator lengths?
a. 2.01 meters.
b. 2.44 meters.
c. 2.21 meters.
d. 2.15 meters.
e. 2.09 meters.
Answer:
The correct option is (d). 2.15 meters.
Step-by-step explanation:
According to the given scenario, the approximate length of an alligator at the 67th percentile is as follows:
The length of an alligator is [tex]X \sim N(2,0.35)[/tex] .
Let us assume the [tex]P_{67}[/tex] be the 67th percentile
[tex]P(X <P67) = 0.67\\\\P(Z < \frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\\emptyset (\frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\ (\frac{P_{67 - 2 }}{0.35} ) = \emptyset^{-1 (0.67)\\\\[/tex]
[tex]\frac{P_{67 - 2 }}{0.35} = 0.44\\\\P_{67} = 2.154[/tex]
Hence, the correct option is (d). 2.15 meters

An isosceles right-angled triangle is shown.
The area of the triangle is 200 cm?.
Work out the value of x.
Answer:
[tex]\boxed{x=4}[/tex]
Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4

if 4 oranges make 1 cup of juice then how much will 6 oranges make
Answer:
1 and 1/2 cups
Step-by-step explanation:
4 oranges = 1 cup
6 oranges / 4 oranges in a cup = 1 1/2 cups
If 4 oranges make 1 cup of juice, then that means 1 orange makes 1/4 cup of juice.
So we know that each orange makes 1/4 cup of juice. We need to find how much juice 6 oranges will make. To do that, multiply 1/4 by 6.
1/4 times 6 equals 6/4 or 1 and 1/2.
6 oranges will make 1 and 1/2 cups of juice.
