Answer:
7 large boxes and 2 small boxes
Step-by-step explanation:
if you take 350 and times it by 7 you get 2450 then add 2 small boxes which are 50 each and you have 2550 and 5 more large boxes then small
The contractor purchased 2 no. of small boxes and 7 large boxes.
What is a linear equation ?A linear equation is an algebraic equation of highest degree 1.
According to the given question A contractor needs to buy nails to build a house.
The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails.
The contractor bought 5 more large boxes than small boxes,So assuming he bought x no. of small boxes.
∴ He bought (x+5) nos. of large boxes.
So, 50(x) + 350(x+5) = 2550.
50x + 350x + 1750 = 2550.
400x = 2550 - 1750.
400x = 800.
x = 2.
∴ Large no. of boxes he purchased is 7.

Answer:
6, 7, and 14 feet.
Step-by-step explanation:
x+2x+x-1=27
4x-1=27
4x=27+1
4x=28
x=7
2x=14
x-1=6
So the three sides, in order, are 6, 7, and 14 feet.
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

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.

C. bite the ratio of money Jack spent on music to money Jack spent on shoes. simplify your answer period what is the ratio mean? what fraction is equivalent to the ratio
Answer:
A) Fraction = 3/5, Percentage = 60%
B) Fraction = 1/15 , Decimal = 0.083333 ≈ 0.08
C) Ratio = 1:9, Fraction = 1/9
Step-by-step explanation:
A) The total amount of money Jack received = $75
Jack's spent on shoes = $45
The proportion he spent on shoes
= $45/$75
= 3/5
Converting this fraction to percentage
= 3/5 × 100% = 60%
B.What proportion of his birthday money went toward music?
The total amount of money Jack received = $75
Jack's spent on music = $5

= 1/15 = 0.0833333333
It is a repeating decimal.
Approximately to the nearest hundredth = 0.08
C. Write the ratio of money Jack spent on music to money Jack spent on shoes.
The ratio of money spent on music to the ratio of my money spent on shoes

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 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

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.
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.

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.
