And orange contains 100 mg of vitamin C. It is recommended for a person to eat up to 2000 mg of vitamin C in a day. If you eat seven or just throughout the day what percent of your daily intake of vitamin C did you eat. Round to the nearest whole percent
A. 17%
B.35%
C.49%
D.5%
Answer:
[tex]\sf 35 \%[/tex]
explanation:
[tex]\hookrightarrow \sf \dfrac{orange \ juice \ intake}{recommended \ mg} * 100[/tex]
[tex]\hookrightarrow \sf \dfrac{7*100}{2000} *100[/tex]
[tex]\hookrightarrow \sf 35 \%[/tex]
Answer:
B.35%Step-by-step explanation:
100x7=700
So you ate 700mg of Vitamin C by eating oranges 7 times in that day.
Now, lets figure out the percent part
700 n/100x2000
=35%
We didn't even have to round.
So hence, your answer is B.35%

The positive solution of the quadratic equation [tex]\rm 0=-x^2+2x+1[/tex] is x=2.41

What is a quadratic equation?A quadratic equation is a second-degree algebraic equation represented by the:
[tex]\rm ax^2+bx+c=0[/tex]........(1)
Where a, b, and c are the constants and [tex]\rm a\neq 0[/tex]
We know that:

We have:
[tex]\rm 0=-x^2+2x+1\\\rm or \\\rm -x^2+2x+1=0[/tex] ..........(2)
After comparing (1) and (2) we get:
[tex]\rm a=-1, b=2, and \ c=1[/tex]
Put these values in the above formula we get:
[tex]\rm x=\frac{-2\pm \sqrt{2^2-(4)(-1)(1)}}{(2)(-1)}\\\rm x=\frac{-2\pm \sqrt{8}}{-2}\\\rm x=\frac{-2\pm 2\sqrt{2 }}{-2}\\\rm x={1\pm \sqrt{2}}[/tex]
[tex]\rm x=1+\sqrt{2} \ or \ x=1-\sqrt{2} \\\\\sqrt{2} = 1.41\\\rm so \ x= 1+1.41 \ or \ x= 1-1.41\\\rm x=2.41 or \ x=-0.41[/tex]

A rectangular carpet has a perimeter of 16m and area 15 m^2. Find the lengths of the carpets sides
While guessing and checking is one way to do this problem, I will show you how to do it algebraically.
Let one side be A
Let the other side be B
2(A+B)=16
A*B=15
First equation because the perimeter is 16 and the second because the area is 15. Now solve the system of equations
A+B=8
A=8-B
Substitute into equation two
B(8-B)=15
-B^2+8b-15=0
B^2-8b+15=0
(B+3)(B+5)=0
B=3,5
A=5,3 respectively
From this we can see that one side is 5 meters long while the other side is three meters long.
Step-by-step explanation
Since we're looking at a rectangle, let's consider its perimeter and area formulas.
Perimeter: 2x + 2y (A rectangle has four sides, with two equal sides, so this is x + x + y + y simplified)
Area: (x)(y) (length x breadth so, x times y)
So we have two equations: 2x + 2y = 16 and x*y = 15. Solve simultaneously. Refer to the attached image.

Ricky is playing a game using 5 cards and a spinner. The cards are numbered 1,2,3,4, and
5 and the spinner is divided into three equal parts. If Ricky picks a card and spins the
spinner, what number would represent the sample size?
options
15
8

Answer:
15
Step-by-step explanation:
The cards have 5 possible outcomes and the spinner has 3 possible outcomes. To find the sample size, you need to calculate the number of possibilities when drawing 1 card and landing on 1 side of the spinner. You can do this by multiplying the possible outcomes together.
5×3 = 15
Therefore, the sample size is 15.

While reviewing last month's finances, Oscar noticed that he had spent $200 on a wedding cake and deposited $500 that he had earned from selling books to a used bookstore. Then, he again spent $127 to buy some new books. Which integer represents the change in Oscar's savings?
Answer:
$173
Step-by-step explanation:
Given the following :
Amount spent on wedding cake = $200
Amount deposited = $500
Amount spent on new books = $127
Change in savings :
Amount deposited - total amount spent
Total amount spent = ($200 + $127).= $327
Hence,
Change in saving = $500 - $327
= $173

What is the length of the longer side of the rectangle?
Use 3.14 for π.
Enter your answer as decimal in the box.
We are given that :
A semicircle is drawn onto the shorter side of rectangle.Shorter side of rectangle measures 4cm. i.e; the diameter of the circle is 4cmArea of the figure is 41.4 cm²Using Formulas:

The length of the longer side of the rectangle will be 8.78 cm.
What is the area?The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.
On one of a rectangle's shorter sides, a semicircle is drawn. The rectangle's shorter side is 4 cm long. The figure has a surface area of 41.4 square centimeters.
Then the length of the rectangle is calculated as,
A = πr² / 2 + l × b
41.4 = (3.14 / 2) × (4/2)² + 4l
41.4 = 6.28 + 4
l = 8.78 cm
The length of the longer side of the rectangle will be 8.78 cm.

Ms. Waters, the manager of Paradise Lake, just ordered a duck and goose food dispenser. She plans to use a paper cone to hold the pellets. The machine is set to dispense no more than 350 cm3 of food for each token. The cones are 12 cm. in diameter. How tall must the cone be to hold the food
Step-by-step explanation:
Equation for the volume of a cone is
V = (pi(r^2)h)/2
Plug in the known values to get
350 = (pi(6^2)h)/2
To find h, just isolate it by first dividing both sides by 2 and squaring 6 to get
175 = pi(36)h
Then, divide both sides by pi36 to get
h = 175/pi(36)

The table shows the height y (in thousands of feet) of an unmanned aerial vehicle (UAV) x minutes after it begins its descent from cruising altitude.
Write a linear function that relates y to x . Interpret the slope and y-intercept. y = ___
The slope indicates that the height ___ feet per minute. The y-intercept indicates that the descent ____ at a cruising altitude of ___ feet.
1)
[tex]m = \frac{y - y}{x - x} = \frac{55 - 59}{10 - 0} = \frac{ - 4}{10} = - \frac{2}{5} [/tex]
[tex]y = - \frac{2}{5} x + b[/tex]
Since the line passes through the point (0,59), the coordinates of this point satisfies the equation of y;
[tex]59 = - \frac{2}{5} (0) + b[/tex]
[tex]b = 59[/tex]
Final answer:
[tex]y = - \frac{2}{5} x + 59[/tex]
The average number of customers that visited a particular store during the past year is 200 per day and a standard deviation of 25 customers per day. The probability that x>200 is:
Answer:
0.5
Step-by-step explanation:
Considering we are given a mean and standard deviation, the distribution of the data is likely to be a normal or Gaussian distribution, i.e. a symmetrical, bell-shaped distribution of probability density, peaked at the mean;
Such a distribution has 0.5 probability each side of the mean;
So, if the mean is 200 then, the probability that the number of customers is greater than 200 (x > 200), according to this mean, is 0.5;
As a normal distribution is symmetrical, this is also the probability of a number of customers less than 200.

what's the answer to: |x+6|+10=13
x=_ or x=_
Answer:
X= -3 or X=-9
Step-by-step explanation:
Answer: x = -3, x = -9
Step-by-step explanation: |x + 6| + 10 = 13
Firstly, subtract 10 from both sides:
|x + 6| = 3
Since it is an absolute value, separate it into two equations with either outcome:
x + 6 = 3
x + 6 = -3
Solve for x now.
x + 6 = 3
Subtract 6 from both sides:
x = -3
x + 6 = -3
Subtract 6 from both sides:
x = -9

2) () = 2 + 4 − 40 is the total daily cost to produce for x bracelets. The bracelets sell for $8 each. (I kept the numbers in the problem small to make the math easier) a) Create a revenue function b) Create a profit function c) Determine the number of bracelets the company should produce and sell to maximize profit. d) What is the maximum profit?
Answer:
The answer is below
Step-by-step explanation:
Given the cost as C(x) = x² + 4x - 40
a) Since the bracelets sell for $8 each, the revenue from x bracelets is given as:
Revenue = price for each bracelet × number of bracelet
Revenue = 8 × x = 8x
b) Profit (P) = Revenue - Cost
P(x) = 8x - [x² + 4x - 40]
P(x) = 8x - x² - 4x + 40
P(x) = -x² + 4x + 40
c) To maximize profit, the derivative of profit is equal to 0
Hence P'(x) = 0
-2x + 4 =0
2x = 4
x = 2
To maximize profit, the company should produce 2 bracelets
d) The maximum profit is:
P(2) = -(2²) + 4(2) + 40 = -4 + 8 + 40
P(2) = $44
The maximum profit is $44
