Answer:
59.4/ 82.5 = 9/12.5
Step-by-step explanation:
6.6/p = 9/12.15
A fraction equal with another fraction, so we can cross multiply to to have a multiplication equal another multiplication.
6.6 * 12.5 = 9* p
To isolate p (our unknown) we divide both sides by 9
( 6.6 * 12.5) /9 = (9* p)/ 9
( 6.6 * 12.5) /9 = p
82.5 / 9 = p
The proportion is:
6.6/p = 9/12.15, substitute p = 82.5 / 9
6.6/(82.5/9) = 9/12.15, use that: a / (b/c) = (a/1 )*(c/b) = (a*c) / b
(6.6*9)/82.5 = 9/12.5
59.4/ 82.5 = 9 /12.5

Suppose that the supply of x units of a product at price p dollars per unit is given by the following.
p = 20 + 90 ln(2x + 4)
(a) Find the rate of change of supply price with respect to the number of units supplied.
Answer: [tex]\frac{DP}{DX}[/tex] = [tex]\frac{90}{x+2}[/tex]
(b) Find the rate of change of supply price when the number of units is 38.
Answer: $ 2.25
(c) Approximate the price increase associated with the number of units supplied changing from 38 to 39.
ANSWER NEEDED: $
Answer:
(a) dp/dx = 90/(x+2)
(b) $2.25
(c) approx = $2.25
exact = $2.22
Step-by-step explanation:
[tex]p = 20 + 90 \ln(2x + 4)[/tex]
(a) To find the rate of change, differentiate [tex]p[/tex] with respect to [tex]x[/tex] :
[tex]\implies \frac{d}{dx}(p) = \frac{d}{dx}(20) + \frac{d}{dx}(90 \ln(2x + 4))[/tex]
[tex]\implies \frac{dp}{dx}=0+90\times\dfrac{1}{2x+4}\times2[/tex]
[tex]\implies \frac{dp}{dx}=\dfrac{180}{2x+4}[/tex]
[tex]\implies \frac{dp}{dx}=\dfrac{90}{x+2}[/tex]
(b) Find [tex]\frac{dp}{dx}[/tex] when [tex]x=38[/tex] :
[tex]\implies \frac{dp}{dx}=\dfrac{90}{38+2}[/tex]
[tex]\implies \frac{dp}{dx}=\dfrac{90}{40}[/tex]
[tex]\implies \frac{dp}{dx}=2.25[/tex]
(c) Approximate price increase associated with the number of units supplied changing from 38 to 39 is [tex]\frac{dp}{dx}[/tex] when [tex]x=38[/tex]
[tex]\implies \$2.25[/tex]
Exact price increase:
[tex]\implies \left. p \right_{x=39}-\left. p \right_{x=38}\\\\\implies [20 + 90 \ln(2 \times 39 + 4)]-[20 + 90 \ln(2\times38 + 4)]\\\\\implies 416.6047323...-414.3823972...\\\\\implies 2.222335133...\\\\\implies \$2.22[/tex]
A square pyramid with a=20 mm and b=96mm what is the length of side c
Which does not have a perimeter of 8x+8.
Answer:
Figure 1 does not have perimeter 8x +8
Step-by-step explanation:
Perimeter of shape is the sum of all the sides.
Perimeter of figure 1 = 2x +2 + x + 2x + 2 +x
= 2x + 2x + x + x + 2 + 2 {Combine like terms}

question: %({<520>545]#-[101])
<=lowest number
>= highest number
{=start grid
}= end grid
the x axis of the grid starts at the lowest number and ends at the highest. The reverse is applied for the y axis
#- defines the intersection as the result of an operation made between the 2 numbers that intersect on the grid
[n] = the nth intersection
X axis takes priority in operations
%()= return the final result of any actions defined inside brackets
for decimal numbers only the first 4 digits matter

Alvin was making chicken parmesan, but he only wanted to make 1/2 of the recipe. If the whole recipe called for 1/2 of a cup of bread crumbs, how many cups will he need to make 1/2 of the recipe?
Answer:
1/4 cup
Step-by-step explanation:
To make half a recipe, each of the quantities in the recipe must be multiplied by 1/2. Alvin will need ...
(1/2) × (1/2 cup) = 1/4 cup
of bread crumbs.

Based on the sequence of numbers, the next two numbers in the sequence will be:
8688 = 75971 = 1What are the next numbers?The numbers on the right side of the equation are meant to show to number of circles on all the numbers on the left side.
For instance:
The number six is drawn such that it has a single circle in it = 6
The number of sixes in the first number are 3 so there will be 3 circles.
The number of circles in 8688 will be 7 because each "8" has 2 circles.
The number of circles in 5971 will be 1 because 9 is the only number drawn with a circle.

The height of a triangle is 2 centimeters greater than the base. The area of the triangle is 161.5 square centimeters. Find the length of the base and the height of the triangle.
Answer:
H = 19 cm
B = 17 cm
Step-by-step explanation:
A = (H x B) / 2 (formula for the area of a triangle)
161.5 = ((X + 2)(X)) / 2 (with X acting as the base)
323 = X^2 + 2X
0 = x^2 + 2x - 323
(X - 17) (X + 19) = 0
X = 17 or X = -19
You can't have a negative number as a side length so -19 doesn't work.
Because the height is larger than the base, you add the 2 to the one you will use as the height. Then just add the units (cm) because the area is in cm squared.
In how many ways can the letters in the word "STATISTICS" be arranged if the letter T must be the first
letter & no vowel can be the last letter?
Answer:
6
Step-by-step explanation:

Josh mixes water and flour in the ratio 1:4. How much flour should be mixed with 2.5 cups of water?
Answer:
10 cups of flour
Step-by-step explanation:
Ratios tell you how much of one thing there are compared to another.
It is stated that the ratio of water to flour is 1:4.
This means for every 1 cup of water, there are 4 cups of flour.
If there are 2.5 cups of water, we do 2.5 x 4 = 10 cups of flour.

Which of the following is an example of a rational number that is an integer
and a whole number?
Answer:
-2/5 , -7/13 , 7/11 , 5/84
1. The answer would be "-15" since integers are composed of whole numbers and negatives.
2. The statement "Every real number is a rational number." is false, since real numbers are composed of both rational and irrational numbers.
3. The number "8.52624 . . ." because this is the only non-terminating number, which makes it the only irrational number on the list.
4. "Irrational numbers cannot be classified as rational numbers." is the only correct statement. No irrational numbers can be rational numbers, and the opposite is also true.
5. Only the statement "Every irrational number is a real number." is true.
i hope this work for you
