Answer:
a. [tex]\frac{-11}{24}[/tex]
b. [tex]\frac{-3}{2} \\[/tex]
c. [tex]\frac{31}{7}[/tex]
d. [tex]\frac{11}{16}[/tex]
11, 3, 31, 11 = code
Step-by-step explanation:
a. [tex]\frac{-1}{6}\\[/tex] * 2[tex]\frac{3}{4}[/tex] =
2[tex]\frac{3}{4}[/tex] = [tex]\frac{4*2+3 }{4}[/tex]= [tex]\frac{11}{4}[/tex]
[tex]\frac{-1}{6}\\[/tex] * [tex]\frac{11}{4}[/tex] = [tex]\frac{-1*11}{6*4}[/tex] = [tex]\frac{-11}{24}[/tex]
b. [tex]\frac{3}{16}[/tex] / [tex]\frac{-1}{8}[/tex] =
[tex]\frac{3}{16}[/tex] * [tex]\frac{8}{-1}[/tex] = [tex]\frac{3*8}{16*-1} \\[/tex] = [tex]\frac{24}{-16}[/tex] = [tex]\frac{-3}{2} \\[/tex]
c. [tex]\frac{-31}{56}[/tex] * [tex]\frac{-8}{1}[/tex] = [tex]\frac{31}{7}[/tex] (you can reduce 8 & 56 by dividing by 8: 56/8=7 & -8/8= -1)
d. 1 [tex]\frac{7}{8}[/tex] / 2[tex]\frac{8}{11}[/tex] =
1 [tex]\frac{7}{8}[/tex] = [tex]\frac{8*1+7}{8}[/tex] = [tex]\frac{15}{8}[/tex]
2[tex]\frac{8}{11}[/tex] = [tex]\frac{11*2+8}{11}[/tex] = [tex]\frac{30}{11}[/tex]
[tex]\frac{15}{8}[/tex] * [tex]\frac{11}{30}[/tex] = [tex]\frac{11}{16}[/tex] (you can reduce 15 & 30 by dividing by 15: 15/15=1 & 30/15 = 2)
Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches
Answer:
The height of the right circular cylinder is 4.55 inches ⇒ b
Step-by-step explanation:
The formula of the surface area of a right circular cylinder is
S.A = 2πrh + 2πr², where
r is its radiush is its height∵ The surface area of a right circular cylinder is 300 square inches
∴ S.A = 300 in.²
∵ Its radius is 5 inches
∴ r = 5 in.
∵ π = 3.14
→ Substitute them in the rule above
∵ 300 = 2(3.14)(5)(h) + 2(3.14)(5)²
∴ 300 = 31.4h + 157
→ Subtract 157 from both sides
∵ 300 - 157 = 31.4h + 157 - 157
∴ 143 = 31.4h
→ Divide both sides by 31.4
∵ 4.554140127 = h
∴ 4.55 = h
∴ The height of the right circular cylinder is 4.55 inches

A sales associate in a store earns $325 per week, plus a commission equal to 4% of her sales. This week, her goal is to earn at least $475. At least how many dollars worth of sales does she need to make in order to hit her goal. (Hint: 4%=0.04)
Answer: She will need to sell at least ($3,750) of merchandise in order to reach her goal of $475 in one week.
Step-by-step explanation:
It is GIVEN that she earns a weekly salary of $325 and she needs $475.
Subtract $325 from $475 (425-325)=150.
Now we know that she needs $150 to earn on top of her salary to reach her goal of $475.
I used a calculator to plug in (x)0.04=150
I received 3750 as my answer
$3750 times 4%= 150

Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −135 mg/L . It is estimated that the chloride concentration will change −2115 mg/L the next year. What is the total change that will likely occur in 2 years?
Complete question :
Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −1 3/5 mg/L . It is estimated that the chloride concentration will change −2 1 /15 mg/L the next year. What is the total change that will likely occur in 2 years?
Answer:
- 3 2/3 mg/L
Step-by-step explanation:
Given that:
Change in concentration during first year = - 1 3/5 mg/L
Estimated change in second year = - 2 1/15 mg/L
Total change in concentration likely to occur over the 2 years:
This will be the sum of the concentration in the first and second year:
[-1 3/5 + (-2 1/15)] mg/L
-1 3/5 - 2 1 /15
-8 / 5 - 31 /15
L. C. M of 5 and 15 = 15
(-24 - 31) / 15
= - 55 / 15
= - 3 10/15
= - 3 2/3 mg/L

A bag is filled with 100 marbles that are all the same size and shape each marble has one color the number of marbles in a colors are listed below 21 green 35 blue 18 red 26 yellow one marble is randomly selected from the bag which word best describes the probability of it being green
Answer: 21/100
Step-by-step explanation:
Number of green marbles = 21
Number of blue marbles = 35
Number of red marbles = 18
Number of yellow marbles = 26
Total number of marbles = 100
The probability of choosing a free marble will be:
= Number of green marbles / Tot number of marbles
= 21 / 100

We can see that the rectangles are congruent meaning they can be mapped onto one another perfectly and therefore 13 and t make up a rectangle the same size and shape as the second one. This means that 13+t will add to 17 since the rectangle they make up is congruent to the second one

Graph the function and its parent function. Then describe the transformation. f(x) = x + 3
Please Help ASAP
We have graphed the function f(x) = x + 3 and it's parent function f(x) = x in the image attached below and the parent graph has been transformed 3 units up onto the y axis.
What is a function ?A function is a set of outputs for some set of inputs we can graph function s in x-y co-ordinate.
According to the given question we have to graph a function and it's parent function.
We know a parent function is a function which is free from any transformation so parent function of f(x) = x + 3 is f(x) = x.
f(x) = x implies y = x.
Some points are (-5,-5), (0,0), (2,2).
Graph of these function is attached in the image below.
f(x) = x + 3 here when x = 0 y = 3 implies the whole graph has been transformed 3 units up onto the y axis.
Image of this transformed graph has also been attached.
