The figure is made up of two identical semicircles enclosed within a rectangle. Find the perimeter of the shaded region using 3.14
Answer:
61.74
Step-by-step explanation:
so u start off by solving for ghe semicircles.
the formula I wrote for it was:
1/2(3.14)(3)(3)=14.13
then i multiplied it by 2 because the other semicircle so you get:
28.26
then u find the area of the rectangle and subtract 28.26.
15x6=90
90-28.26=61.74
Anyone understand this???
Answer: 26
We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

Hi!
1.Well, let's try simplifying 4:18 so we can compare.
If we divide 4:18 by 2, we get 2:9
We can see that 2:9 =/= 2:12
Thus, the two are not equivalent ratios.
2. 5:20 and 15:60 are equivalent, 5:20 x 3 to both numbers is 15:60
Therefore, It is equivalent.
3. 17 times 4 is 68 and 3 times 4 is 12. 17:3 and 68:12 are equivalent because you can times and divide them into each other
4. He read for 180 minutes.
You can find that because every time he practices math for five minutes, he reads for 20, and 45 is 5, 9 times. So you multiply 20 by 9.
5. If he eats 3 slices in 2 minutes, he will have eaten 15 pieces in 10 minutes.
6. For this one, I hope my calculations are correct, but I do NOT think August made the correct recipe using the correct ratio.
If #6 is wrong, I sincerely Apologize, but I know for a fact #5 is Correct.

You should eat at least 2,000 calories per day. Today, you have eaten a total of 1,200 calories and you plan to eat pizza for dinner. If each slice of pizza is 352 calories. How many slices of pizza should you eat for dinner?
Answer:
Step-by-step explanation:
We know you need at least 2,000 calories, and we have eaten 1,200 of those. To find how many we have left we need to subtract the calories we have eaten from our goal (Shown below)
\(2000 - 1200 = 800\) calories we have left.
Now we know each slice of pizza is 352 calories, and we need 800 calories. If we divide 800calories remaining by 352calories a slice, we can find how many slices of pizza we need to eat.
\(800 / 352 = 2.27\) slices of pizza needed to meet the minimum calorie requirement.
Good luck getting exactly 2.27 slices of pizza. Because we need a minimum of 2.27 slices, we should round up to 3 slices to get all the calories needed for the day.
Answer: 3 slices of pizza for dinner

A survey showed that students were 2:3 in favour of the new team logo. In all, 780 people were surveyed, how many were in favour of the new logo?
156 students
312 students
468 students
520 students
Answer:
312 students
Step-by-step explanation:
---- If 2 : 3 is a ratio of "in favour" vs "against to" then
\(\frac{2}{3}\) = \(\frac{x}{780-x}\)
3x = 2(780 - x)
3x + 2x = 1560
x = 312
If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

We know that the equation 6(t+2) can be simplified to 6*t+6*2, also 6t+12. This causes any statements saying a variable with a certain value applies to one side also applies to the other.
Answer:
- The value of both expressions when t = 3 is 30
- The value of both expressions when t = 7 is 54
- The expressions are equivalent
Step-by-step explanation:
Plug in each value of t into the expressions:
6t + 12, when t = 3 equals 30
6t + 12, when t = 7 equals 54
6(t + 2), when t = 3 equals 30
6(t + 2), when t = 7 equals 54
We have the same answers for both expressions, meaning they are equivalent.

Natasha had d dollars. She bought 2 ice creams which cost x dollars each. How much money does she have left?
Answer:
d-2x
Step-by-step explanation:
d is the amount of dollars she had, 2x is the amount of money she used to buy ice creams.
We can write an equation to resemble the problem.
We can write "2x" since she bought 2 ice creams and the price of each is unknown.
We can subtract that by "d" to find how much money she has left.
Put everything together.
2x - d

A truck driver drove 150 miles in 3 hours. At that rate, how long will it take the drive to travel 500 miles?
I’m bad at math and confused. Help?
=====================================================
Explanation:
We'll use the values in the first sentence to find the rate or speed.
distance = rate*time
rate = distance/time
rate = (150 miles)/(3 hours)
rate = 50 miles per hour
Now we can determine the time needed to travel 500 miles
distance = rate*time
time = distance/rate
time = (500 miles)/(50 mph)
time = 10 hours
Answer: 10 hours
Step-by-step explanation:
We can set up a proportion to solve. Let x be equal to the number of hours it takes to drive 500 miles.
\(\displaystyle \frac{150\;miles}{3\;hours} =\frac{500\;miles}{x\;hours}\)
Now, we will cross-multiply.
150 * x = 500 * 3
150x = 1,500
Lastly, we will divide both sides of the equation by 150 to isolate the variable
x = 10 hours

Which of the following equations describes the graph?
1/2x^2 - 2x +1
Step-by-step explanation:
it cannot be negative x as the parabola has a minimum value, the coordinates of turning point is (-1,2)
as it is -1 there has to be a negative sign in equation
so the right one is 2nd one
Answer:
Step-by-step explanation:
the graph is clearly that of a parabola that opens up and has its vertex at (2, -1). The coefficient of x^2 must be + because the parabola opens up.
Using the point-slope formula y - k = a(x - h)^2, and letting 2 replace h and -1 replace k, we get:
y + 1 = a(x - 2)^2 or y = a(x - 2)^2 - 1

Solve the equation. How many total days does the family travel?
(please answer each part of the question and label your answer. Thanks!)
Answer:
Scroll Down Below...
Step-by-step explanation:
Part A: To record an equating defining this position, we can start by canny the total distance camouflaged in d supplementary days. Since the kin drives 350 5 per epoch each surplus era, the total distance marked in d supplementary days is 350d. Adding the beginning 200 5 compelled on the first epoch, the equating enhances:200 + 350d = 1,600Part B: To resolve the equating and find the total number of days the offspring will travel, we need to detach the changeable d. We can start by subtracting 200 from two together hands of the equating:350d = 1,600 - 200350d = 1,400Next, we separate two together parts of the equating by 350 to resolve for d:d = 1,400 / 350d = 4Therefore, the kin will travel for an supplementary 4 days to reach a total distance of 1,600 5.
