Answer:
Jim is correct.
Step-by-step explanation:
Given that:
Total people = 100
People who exercise in morning = 35
People who exercise in the afternoon= 45
People who exercise in the evening = 20
Ratio claimed by Tara = 33:55, 48:88, and 20:65
Ratio claimed by Jim = 35:100, 45:100, and 20:100
To find:
who is correct ?
Solution:
Looking at the ratio claimed by Tara, the ratio are number which are not known to us.
Therefore, the ratio claimed by Tara can not be correct.
Now, looking at the ratio claimed by Jim:
35:100, 45:100, and 20:100
35 is the number of people who exercise in morning.
45 is the number of people who exercise in evening.
20 is the number of people who exercise in night.
and 100 is the total number of people.
Therefore, this ratio represents the "Part-to-whole" ratio.
So, Jim is correct.

What is the slope of this equation?y= -1/2x −3 Question 2 options: 0 -3 -1/2
Answer:
-1/2
Step-by-step explanation:
In the equation y=mx+b..
y and x are the coordinates that go into your function
m is the slope
and b is the y intercept
looking at y=-1/2x-3 i can tell that -1/2 is in the place of m which is slope, and -3 is the y intercept.
150 x + 500 > 2000
What is the solution
Answer:
X > 10
Step-by-step explanation:
One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 80 calories from x grams of protein and y grams of fat. 80= 4x + 9y
If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.
Answer:
6,5g of protein
Step-by-step explanation:
80=4x + 9y
y=6 ( "6 grams of fat")
so: 80=4x+9.6
80-54= 4x
26/4=x
x(protein)= 6,5
Answer:
6.5 grams
Step-by-step explanation:
To find the value of x that corresponds to the given value of y, put that y-value into the equation and solve for x.
80 = 4x +9·6
26 = 4x
26/4 = x = 6.5
There are 6.5 grams of protein in the snack.
Tisha orders a carpet for a room that measures 270 square feet. The salesman says the carpet costs $12.00 per square yard. He explains that since there are 3 square feet for every square yard, tisha needs 90 square yards of carpeting, which cost $1,080. What error did the salesman make? What should be the actual cost of the carpet?
Answer:
What error did the salesman make?
The salesman made an error when convert 270 square feet to yards.
What should be the actual cost of the carpet?
The actual cost of the carpet is $360
Step-by-step explanation:
From the question, we are told that:Tisha orders a carpet for a room that measures 270 square feet.
This means the room needs 270 square feet of carpet
But from the question, we know that the carpet is sold in square yards
We convert square feet to square yards
For our conversion rates
3 ft = 1 yard
9 ft² = 1 square yards(yd²)
270 ft² = x
Cross Multiply
9 ft² × x = 270ft² × 1 yd²
x yd²= 270ft² × 1 yd²/9 ft²
x = 30 yd²
Hence, 270ft² = 30yd²
Cost of carpet =
1 yd² = $12.00
30 yd² =
Cross Multiply
= 30 × $12.00
= $360.00
The actual cost of the carpet is $360
What error did the salesman make?
The salesman made an error when convert 270 square feet to square yards.
He said 270 square feet = 90 square yards
But he was wrong.
270 square feet = 30 square yards.
What should be the actual cost of the carpet?
The actual cost of the carpet is $360
Answer:360 for the actual cost

A dancer took forward and backward steps of equal length during a dance. After taking 16 steps total, she was back at her starting position. How many steps did the dancer take in the forward and backward directions?
8 steps
this is because when she moves front, she takes 1 step back, so 16/2=8

Brittany will be working full time this summer to save for her goal of having 10,000 by the time she is 21. Brittany has an account of 3.5% interest, compounded monthly. She'll turn 17 at the end of the summer. About how much will Brittany have to deposit so that. Her money can grow into 10,00 by the time she's 21?
Answer:
$ 8,695.35
Step-by-step explanation:
This is a compound interest question
Amount after t years = A = P(1 + r/n)^nt
Where P = Initial Amount saved
r = interest rate
t = time in years
n = compounding frequency
A = 10,000
r = 3.5 %
t = 21 - 17 = 4 years
n = Compounded monthly = 12
Step 1
Converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
P = A / (1 + r/n)^nt
Solving our equation:
P = 10000 / ( 1 + (0.035/12)^12 ×4 =
P = $8,695.35
The principal investment required to get a total amount, principal plus interest, of $10,000.00 from interest compounded monthly at a rate of 3.5% per year for 4 years is $8,695.35.

please help At a bake sale there were 50 items sold total. If 5 of the items sold were cookies and the rest were brownies what is the ratio of brownies sold to cookies sold?
Answer:
45:5 or 45 to 5
Step-by-step explanation:
If 5 of them were cookies then that leaves the rest of them (which is 45) to be brownies. So it would be brownies to cookies which equals 45:5

Segment AB has endpoints on the coordinate grid where A is (-18,5) and B is (-4,5). Point Z is located exactly 1/8 of the distance from A to B. Determine the value of the x-coordinate of point Z.
Answer:
The coordinates of point Z is (-16.25, 5)
Step-by-step explanation:
The given information are;
The coordinates of the endpoint A on segment AB = (-18, 5)
The coordinates of the endpoint B on segment AB = (-4, 5)
Therefore, given that the endpoints A and B have the same y-coordinate value, (5), then segment AB is horizontal, and the length of segment AB = -4 - (-18) = -4 + 18 = 14
The point Z located at exactly 1/8 from A to B is given as follows;
[tex]Z = \left (-18 + (-4 - (-18)) \times \dfrac{1}{8} , \ 5 + (5 - 5)\times \dfrac{1}{8} \right ) = (-16.25, \ 5)[/tex]
The coordinates of point Z = (-16.25, 5).

move vertices A B and C to modify the original parallelogram. As you change the parallelogram, notice what happens to the diagonals. How does moving the vertices affect the relationship between the diagonals that you noted in question 2?
Moving the vertices does not affect the relationship between the diagonals. They bisect each other in all cases.
Answer:
Despite changing the vertices, the opposite sides and opposite interior angles of the parallelogram remain equal.
