A survey o 100 people found that 35 people exercise in the morning, 45 people exercise in the afternoon, and 20 people exercise at at night. Tara claims that 33:55, 48:88 and 20:65 are possible ratios from this data. Jim claims that 35:100, 405:100 and 200:100 are possible ratios from the data who is correct? Explain
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.
Solve the following literal equation for x.
ax-b/c=d
Answer:
x = (d + b/c)/a
or x = d/a + ba/c
Step-by-step explanation:
1. ax - b/c = d
2. ax = d + b/c
3. x = (d + b/c)/a (can also be written as x = (d + b/c)*1/a)
4. x = d/a + ba/c
Step 1 is given.
In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.
In step 3, both sides were divided by a.
(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.

Answer:
60 cm
Step-by-step explanation:
remember, the area of a triangle is found by
1/2 b h
or half of the base times the height
so using that plug in the values:
the base is made of two 5s; 2* 5 is 10 so the base is 10cm long
the height is 12cm
so
1/2 * 12 * 10
= 6 * 10
= 60
Answer:
I think its 60
Step-by-step explanation:
To find the area of a triangle you do (height x base) divided by 2
5+5=10
12 x 10 = 120
120 divided by 2 is 60

Answer:
D. y = 76x
Step-by-step explanation:
First you find the gradient, by using the gradient formula
rise over run
380 - 228
---------------- <- division sign
5 - 3
152/2 = 76
Hence y = 76x + c
Find c by subbing points in. I am going to use this as an example (5, 380)
380 = 76(5) + c
380 -380 = c
c = 0
Hence, y = 76x

Explicit formula -6,-10,-14
Answer:
Tn = -6 + (n - 1)(-4)
Step-by-step explanation:
The explicit formula is this: Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference.
The first term is given to you and that is -6.
The common difference is -4 because:
d = -10 - (-6)
d = -10 + 6
d = -4
Hence: Tn = -6 + (n - 1)(-4)

A golf course charges $18 to golf 18 holes and $7 for a cart for a no-member.
To become a member you have to pay $560 and $5 for a cart for each round
of 18 holes you golf. How many times would you have to golf 18 holes with a
cart to justify becoming a member?
*
Answer:
at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..

A stage for a wedding venue needs to measure 280 square feet.The length is listed as (x-12), and the width is listed as (x-18).What are the dimensions of the stage?
Answer:
Length: 20, Width: 14
Step-by-step explanation:
(x-12)(x-18)
x^2-30x+216=280
x^2-30x-64=0
x=32,-2
Plug 32 into x, and see if it equals 280
10x² - x - 2 = 0

-4(6-r)=12
-24-4R=12
-4R=36
R=-9
Answer:
His answer is wrong.
Step-by-step explanation:
-4(6-R)=12 <-- Since R is negative, -4 times -R results in a positive so, 4R.
-24+4R=12
+24 +24

A square has an area of 200 square feet. Between what two consecutive integers would the
length of each side fall?
HELP ME PLEASE
Answer:
14 & 15
Step-by-step explanation:
The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].
So we take [tex]s = \sqrt{200} = 14.14[/tex]
And this is between the integers 14 and 15.
