The recommended amount of vitamin c for young adults is 75 milligrams. You drank a new sports drink that has 165 mg of vitamin C. What precent of the daily amount of vitamin C did you drink??
Answer
not sure
Step-by-step explanation:
Answer: 220%
Step-by-step explanation:
165 of 75 can be written as:
165 /75
To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100
165 /75 × 100 /100 = ( 165 × 100 /75 ) × 1 /100 = 220 /100
Therefore, the answer is 220%
What value of x makes the equation -2(-3x+7))=-2(1+8x)
Answer:
x = 12/22 = 0.545
Step-by-step explanation:
-2(-3x+7))=-2(1+8x)
Distrubute '-2's to brackets.
(6x-14)=(-16x-2)
Collet the 'x' in one place.
22x=12
Leave 'x' alone.
x=12/22

Answer:
f(g(t)) = 2t² + 1
Step-by-step explanation:
You can solve this simply by substituting g(t) into f(t), and solving for f(g(t)):
[tex]f(t) = 2t + 5\\\\g(t) = t^2 - 2\\\\f(g(t)) = 2(g(t)) + 5\\\\f(g(t)) = 2(t^2 - 2) + 5\\\\f(g(t)) = 2t^2 - 4 + 5\\\\f(g(t)) = 2t^2 + 1[/tex]

Willow has 3/4 of a gallon of milk left that has an expiration date in 6 days. If she splits the milk equally among her next 6 bowls of cereal, how much milk will she use in each bowl
Answer:
[tex]\dfrac{1}{8}\ \text{gallons}[/tex]
Step-by-step explanation:
Amount of milk remaining is [tex]\dfrac{3}{4}\ \text{gallons}[/tex]
Number of bowls is [tex]6[/tex].
So, each bowl will contain
[tex]\dfrac{\dfrac{3}{4}}{6}[/tex]
[tex]=\dfrac{3}{4}\times \dfrac{1}{6}[/tex]
[tex]=\dfrac{3}{24}[/tex]
[tex]=\dfrac{1}{8}\ \text{gallons}[/tex]
Hence, each bowl will have [tex]\dfrac{1}{8}\ \text{gallons}[/tex] of milk.
4. The celluloid bakery sells two types of cinnamon buns. They must sell at least 35 and not more than 95 cinnamon
strawberry raisin buns per day. Each day the number of cinnamon strawberry raisin buns cannot exceed twice the number of cinnamon chocolate mango buns baked. The number of cinnamon strawberry raisin buns cannot exceed 125 per day. If xis the number of cinnamon strawberry raisin buns baked daily and y is the number of cinnamon chocolate mango buns baked daily. What are the constraints.
Answer: 35≤ x ≤95
x ≤ 2y
y≤125
Step-by-step explanation:
In an optimization problem, a constraint is a condition with variables that the solution must meet.
Let x = Number of cinnamon strawberry raisin buns.
y = Number of cinnamon chocolate mango buns baked.
"at least 35 and not more than 95 cinnamon strawberry raisin buns per day."
⇒ 35≤ x ≤95
"cinnamon strawberry raisin buns cannot exceed twice the number of cinnamon chocolate mango buns baked."
⇒ x ≤ 2y
" cinnamon strawberry raisin buns cannot exceed 125 per day"
⇒ y≤125
Hence, the constraints are:
35≤ x ≤95
x ≤ 2y
y≤125
Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 180 minutes?
Answer:
46.5 miles
Step-by-step explanation:
Average speed × Time in hours = Distance
Average speed = 15.5 Miles per hour
Time = 180 minutes
We convert to hours
60 minutes = 1 hour
180 minutes = x
Cross Multiply
60x = 180
x = 180/60
x = 3 hours
Distance = 15.5 miles per hour × 3 hours
Distance = 46.5 miles
The distance Rico will ride his bicycle is 46.5 miles

Katrina is going to order sweatshirts for her girls mentoring group. The sweatshirts will have the group logo printed on the front. Katrina asks two local companies to give her a price.
• MH Designs will charge $21.50 for each of the sweatshirts.
• Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.
Justify how to determine the number of sweatshirts Katrina would need to order from
each company for the costs to be the same.
Answer:
Katrina would need to buy 20 sweatshirts.
Step-by-step explanation:
The number of sweatshirts Katrina would need to order from each company can be determined by forming the linear equation in two variables.
Given :
Katrina is going to order sweatshirts for her girl's mentoring group.Katrina asks two local companies to give her a price.MH Designs will charge $21.50 for each of the sweatshirts. Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.
So, the cost for ordering the sweatshirt from the company MH Design is:
[tex]21.50x = c[/tex]
Now, the cost for ordering the sweatshirt from the company Print Rich is:
18y + 70 = c'
Given that the number of sweatshirts Katrina would need to order from each company for the costs to be the same. So :
21.5x = 18y + 70
Now, put the value of x and y so, that in the above equation, both sides become equal.

In a game of luck, a turn consists of a player rolling 121212 fair 666-sided dice. Let X=X=X, equals the number of dice that land showing "111" in a turn. Find the mean and standard deviation of XXX.
Answer:
mean = 2
standard deviation = 1.3
Step-by-step explanation:
For a binomial random variable X, we can use this formula for mean:
meanX = np
We use this formula for the standard deviation:
sdX = sqrt(np(1 - p))
--------------------------------------------------------------------------------------------------
Since a turn consists of rolling 12 dice, we have n = 12.
The dice are fair and 6-sided, so the probability that each die lands showing "1" is p = 1/6.
meanX = np
= (12)(1/6)
= 2 dice
sdX = sqrt(np(1 - p))
= sqrt((12)(1/6)(5/6))
≈ sqrt(1.667)
≈ 1.291 dice
The mean and standard deviation of the game of luck are;
Mean = 2
Standard deviation = 1.29
We are told that a turn consists of rolling 12 fair six sided dice.
Thus;
n = 12
Probability of each one six sided die showing 1 is;
p = 1/6
Now,the formula for the mean is;
E(X) = np
Plugging in the relevant values gives;
E(X) = 12 × 1/6
E(X) = 2
Now, for the standard deviation, we will use the formula;
Standard deviation = √(np(1 - p))
Plugging in the relevant values;
Standard deviation = √((12 × 1/6)(1 - 1/6))
Standard deviation = 1.29

A local college recently reported that enrollment increased to 108% percent of last year. If enrollment last year was at 20,000, about how many students enrolled this year? Round to the nearest whole number.
Answer:
the number of students enrolled this year is 21,600 students
Step-by-step explanation:
The computation of the number of students enrolled this year is as follows:
= Number of students enrolled last year × increased percentage
= 20,000 students × 108%
= 21,600 students
hence, the number of students enrolled this year is 21,600 students

The point A = (7,4) is dilated from the origin by a scale factor r = 3. What are the coordinates of A' ?
Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then
[tex](x,y)\to (kx,ky)[/tex]
Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:
[tex](x,y)\to (3x,3y)[/tex]
Using this rule, we get
[tex]A(7,4)\to A'(3(7),3(4))[/tex]
[tex]A(7,4)\to A'(21,12)[/tex]
Therefore, the coordinates of point A' are (21,12).
