Answer:
8 essay-type questions
Step-by-step explanation:
This is the answer because:
1) 2 out of 5 is the same as 2/5
2) Next, we have to get 2/5's denominator to equal 20.
2 x 4/5 x 4 = 8/20
3) 8/20 means that 8 of the test questions are essay-type

Frank had 90 flyers to hang up around the school. After
giving the same number of flyers to each of three
volunteers, he had 12 left to hang up by himself.
Find the value of the variable in the story.
•18
•30
•28
•26
Answer:
26 per volunteer
Step-by-step explanation:
90-12=78
78/3=26
Answer:
26
Step-by-step explanation:
90 - 12 = 78, 78 / 3 equaling 26.

At the city museum, child admission is $6.00 and adult admission is $9.60. On Tuesday, 177 tickets were sold for a total sales of $1350.00. How many adult
tickets were sold that day?
80 adult tickets were sold that day.
This is a two equation problem.
First, let:
a = adult tickets
c = child tickets
[tex]6c + 9.6a = 1350[/tex]
[tex]c + a = 177[/tex]
Now, solve for either variable (c or a). We're going to isolate "c" in the second equation and plug it into the first.
[tex]c + a = 177[/tex]
[tex]c = 177 - a[/tex]
Plug it in:
[tex]6(177 - a) + 9.6a = 1350[/tex]
[tex]1062 - 6a + 9.6a = 1350[/tex]
[tex]1062 + 3.6a = 1350[/tex]
[tex]3.6a = 288[/tex]
[tex]a = 80[/tex]
Now, plug in 80 for "a" in either of the equations to find "c."
[tex]c + (80) = 177[/tex]
[tex]c = 97[/tex]
Rather than solving algebraically, as shown above, you can also graph the two equations, and wherever they intersect will be the solution.

1-3 Function Operations and Composition Jim was given three functions and asked to determine f + (gon). The functions were f (x) = x2 g(x) = 3x + 1, and h(x) = 2x. Jim started by writing the problem as (r + (gon))(x) = x2 + 2(3x + 1). What was Jim's mistake? What is the correct solution? O A Jim omitted the x in h(x): [ + (g = n)) = 7x2 + 2x B. Jim should have added f and g first; ( + (gon)) = 4x2 + 6x + 1 O C. Jim incorrectly performed h og instead of goh: (f + g - h)) = x2 + x + 1. OD D. Jim did not follow the order of operations, I + (g o h)) = x2 + 6x + 2.
Answer:
Step-by-step explanation:
Given the functions:
f (x) = x^2
g(x) = 3x + 1
h(x) = 2x
We are to look for f + (goh)
First we need to get the composite function goh
goh = g(h(x))
g(h(x)) = g(2x)
To get g(2x) we will substitute x in g(x) as 2x as shown below:
Given g(x) = 3x+1
g(2x) = 3(2x)+1
g(2x) = 6x+1
f + goh = x² + (6x +1)
f + goh = x² + 6x +1
Jim wrote goh as 2(3x+1) instead of 3(2x) + 1. The composite function that Jim looked for was hog not goh.
The correct solution is f + goh = x² + 6x +1
What is the value of x?
45°
(2x - 5)°
Answer:
x=70
Step-by-step explanation:
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Divide 140 by 2 to get X=70
Margaret said the exact product of 602 and 341 is 205,282. Is she correct? Use paper and the standard algorithm to support your reasoning.
Answer:
Yes, she is. The exact product of 602 and 341 is 205,282.
Step-by-step explanation:
To determine the exact product of 602 and 341, both numbers must be multiplied, obtaining the result. To do this, said number can be decomposed, to facilitate the operation and to be able to corroborate the accuracy of the result.
So, we can multiply 602 by 300, plus 602 by 40 and 602 by 1, and add the results.
Therefore, since 602 times 300 is equal to 180,600 (602 x 300 = 180,600); that 602 times 40 is equal to 24,080 (602 x 40 = 24,080); and since 602 times 1 is equal to 602, all those values must be added.
So 180,600 plus 24,080 equals 204,680. And in turn, 204,680 plus 602 equals 205,282. Therefore, the proposed result is correct.

the product of the ages of a father and his son is 576.if the father is 18 years younger than 5 times his son .how old is each?
Answer:
[tex]F = 45.4[/tex]
[tex]S = 12.68[/tex]
Step-by-step explanation:
Given
Represent the sons age with S and the father's age with F
[tex]S * F = 576[/tex]
[tex]F = 5S - 18[/tex]
Required
Determine F and S
Substitute 5S - 18 for F in the first equation
[tex]S * (5S - 18) = 576[/tex]
Open Bracket
[tex]5S\² - 18S = 576[/tex]
Equate to 0
[tex]5S\² - 18S - 576 = 0[/tex]
Solve using quadratic formula:
[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 5[/tex]
[tex]b = -18[/tex]
[tex]c = -576[/tex]
[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]S = \frac{-(-18)\±\sqrt{(-18)^2 - 4*5*-576}}{2 * 5}[/tex]
[tex]S = \frac{18\±\sqrt{324 + 11520}}{10}[/tex]
[tex]S = \frac{18\±\sqrt{11844}}{10}[/tex]
[tex]S = \frac{18\±\108.8}{10}[/tex]
[tex]S = \frac{18+108.8}{10}[/tex] or [tex]S = \frac{18-108.8}{10}[/tex]
[tex]S = \frac{126.8}{10}[/tex] or [tex]S = \frac{-90.8}{10}[/tex]
[tex]S = 12.68[/tex] or [tex]S = -9.08[/tex]
Since, age can't be negative.
We have that:
[tex]S = 12.68[/tex]
Recall that:
[tex]F = 5S - 18[/tex]
[tex]F = 5 * 12.68 - 18[/tex]
[tex]F = 45.4[/tex]
Hence:
The father is 45 years old and the son is 13 years old (Approximated)
What is the sum of -4 1/2 and 10 1/3 show work plz
Answer:
5 5/6
Step-by-step explanation:
Change the mixed numbers to improper fractions, and you get -9/2 + 31/3, which adds up to 35/6, then divide 35 by 6, which changes it back to a mixed number, 5 5/6.
1. Eighty-nine percent of Americans polled are in favor of arts education being taught in public
schools.
a. Does the above numerical value describe a parameter or a statistic?
b. After reading the above statement, you decide to campaign for the arts in education and
use the statement: "A majority of Americans are in favor of art education, which shows
their love of arts. Americans support ballet teaching in public schools." What branch of
statistics would you be applying?
Answer:
a. parameter
b. descriptive statistics
Step-by-step explanation:
The values of the population charactersitics are summarized by certain numerical descriptive measures called parameters.
The observations composing a sample are used to calculate a corresponding numerical descriptive measure called a statistic.
a. The percent of Americans is of a population and therefore it is a parameter not a statistics.
b. Descriptive statistics deals with the collection, summarization and display of data.
Inferential statistics deals with conclusions drawn based on a sample.
This is descriptive statistics because it is displaying of data collected from a population of America.

The Pappas family has two cats, Zeus and Athena. Together they weigh thirteen pounds. Zeus weighs 5 pounds less than Athena. How much does Athena weigh?
Given:
Combine weight of two cats, Zeus and Athena = 13 pounds
Zeus weighs 5 pounds less than Athena.
To find:
The weight of Athena.
Solution:
Let x pounds be the weight of Athena.
Zeus weighs 5 pounds less than Athena.
Weight of Zeus = x - 5 pounds
Combine weight of two cats, Zeus and Athena = 13 pounds
[tex]x+(x-5)=13[/tex]
[tex]2x-5=13[/tex]
Add 5 on both sides.
[tex]2x=13+5[/tex]
[tex]2x=18[/tex]
Divide both sides by 2.
[tex]x=\dfrac{18}{2}[/tex]
[tex]x=9[/tex]
Therefore, the weight of Athena is 9 pounds.

Write 3.65 x 10^5 in standard notation.
Answer:
365,000Step-by-step explanation:
3.65 ⋅ 10 = 36.5
3.65 ⋅ 100 = 365
3.65 ⋅ 1000 = 3,650
3.65 ⋅ 10000 = 36,500
3.65 ⋅ 100000 = 365,000
There are 5 zeroes on the last one.
This means that 100,000 is 10 to the power of 5.

What is the correct equation of the line shown below?
Answer: Y= 3/2x + 3
Step-by-step explanation:
Using the Y =mx+b formula, you count how many units it is going up and that is the numerator. Then you count how many units it's going to the right, and that's the denominator. Then the starting point is (0, 3) so now you plug those in and b is the starting point and the fraction is mx so you are left with the answer y= 3/2x+3
