A piece of lumber is 17 feet long. You cut the lumber into logs that are 18 inches long.
How many inches of lumber are remaining?
17 feet x 12 inches per foot = 204 total inches.
204 inches / 18 inches = 11.33
They cut 11 pieces and had 12x 0.33 = 4 inches remaining.
Answer:
186 inches
step by step: multiple 17x12 then subtract ur answer from 18 theres ur answer
Alonzo works as a car detailer. He charges $165 per car. He is planning to move out of his parents' house and rent his first apartment. He will need to pay $105 for application fees, $895 for security deposit, and first and last months' rent at $1,120 per month. He has $1,919 in savings. How many cars must he detail to have enough money to rent the apartment?
Answer:
2 cars
Step-by-step explanation:
105 + 895 + 1120 = 2120
He has to pay 2120 of downpayment
2120 - 1919 = 201
Subtract what he already has
He needs 201 more dollars to rent his first apartment
He needs to do 1.21818182 cars...
You cant do 1/5 of a car so he has to do 2 cars
At Rhonda’s diner, 5 loaded baked potatoes and 4 cheeseburgers provide 4830 calories. 1 loaded baked potato and 4 cheeseburgers provide 2630 calories. Find the calorie content of each item.
Answer:
Potato: 550 calories
Cheeseburger: 520 calories
Step-by-step explanation:
Equation:
5p + 4c = 4830
p + 4c = 2630
5p + 4c = 4830
p + 4c = 2630 ----------> p = -4c + 2630
5(-4c+2630) + 4c = 4830
-20c + 13150 + 4c = 4830
-16c + 13150 = 4830
-16c = -8320
C = 520
Cheeseburger = 520 calories
p + 4(520) = 2630
p + 2080 = 2630
p = 550
Potato = 550 calories
if i have 789.4 and my mom has 449.7 how much will we both have
Answer:
1239.1
Step-by-step explanation:
x + y = z
x = 789.4 (your money)
y = 449.7 (Your mom's money)
z = Total amount of money.
789.4 + 449.7 = z
789.4 + 449.7 = 1239.1
z = 1239.1

Why is this divergent?
Step-by-step explanation:
f(x) = 40 (2 + e⁻ˣ) / x
If we say g(x) = 1 / x, then:
0 < g(x) < f(x)
g(x) diverges. and f(x) > g(x), so f(x) also diverges.

Find the least common multiple (LCM) of 12 and 16
==================================================
Method #1
Multiply the two values to get 12*16 = 192
Then divide over the GCF 4 getting 192/4 = 48
------------------
Method #2
List out the multiples of each and see what they have in common
Multiples of 12 = {12, 24, 36, 48, 60, 72, 84, 96, ...}
Multiples of 16 = {16, 32, 48, 64, 80, 96, ...}
We see that 48 is the smallest common multiple.
-------------------
Method #3
Find the prime factorization for each
12 = 2*2*3
16 = 2*2*2*2
The unique prime factors are 2 and 3
The prime 2 shows up at most 4 times, so 2^4 = 16 is one factor of the LCM
The prime 3 shows up at most 1 time, so 3^1 = 3 is the other factor of the LCM
The LCM is 3*16 = 48.
The least common multiple (LCM) of 12 and 16 is 48.
To find the LCM, you can use the following steps:
List the multiples of each number until you find a common multiple.
Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, ...
Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, ...
The least common multiple (LCM) is the smallest number that appears in both lists.
The smallest number that appears in both lists is 48.
So, the least common multiple (LCM) of 12 and 16 is 48.

Answer:
C
Step-by-step explanation:
First, add 10% of $7,250 to itself:
7250 + 725 = 7975
Then, take ten percent of 7975:
7975 / 10 = 797.5
Add that to 7975:
7975 + 797.5 = 8772.5
Write the equation of the line, given the y and x-intercepts.
y-intercept = –6, x-intercept = –2
Answer:
Linear equation: (-2,-6)
Quadratic Equation: y = [tex]x^2[/tex] +8x =12
Step-by-step explanation:
see Example image #1 for Linear Equation graph
See Example image #2 for Quadratic Equation graph
Quadratic Equation Explanation:
x = -2 an x = -6 are the two real distinct solutions for the quadratic equation, which means that x+2 and x+6 are the factors of the quadratic equation.
( x + 2 ) ( x + 6 ) = 0
Expand ( x + 2 ) ( x + 6 ) using the FOIL Method.
x ⋅ x + x ⋅ 6 + 2 x + 2 ⋅ 6 = 0
Simplify and combine like terms.
[tex]x^2[/tex] + 8 x + 12 = 0
The standard quadratic equation using the given set of solutions{ − 2 , − 6 } is
y = [tex]x^2[/tex] + 8 x + 12 .

Six more than the product of seven and a number is 55.
Which equation and solution correctly represent this sentence?
7 x + 6 = 55; x = 7
7 X+6 = 55; X= 49
X/7 + 6 = 55: x= 7
X/7 + 6 = 55; X= 49
The equation for the given situation is 7x+6=55 and the solution is x=7. Therefore, option A is the correct answer.
The given statement is six more than the product of seven and a number is 55.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Step-by-step explanation:
A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He believes that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 136 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 126 mm Hg and the standard deviation of the sample to be 18 mm Hg.Based on this information, answer the questions below.What are the null hypothesis and alternative to be used for the test (ie, less than, less than or equal to etc)H0 is μ= ____ _______( 18,136, 126) pick oneH1 is μ = _____ _____ (18,136,126) pick oneIn the context of this test what is the type I error? Pick one in the parathensisA type I error is ______(rejecting or failing to reject) that the μ is____________ (less than , equal to, etc) (18,136,126) when in fact μ is__________ ( less than, greater to , etc) (18,136,126)Suppose the researcher decides not to reject the null hypothesis. What sort of error might he be making? (type I or type II)
Answer:
Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 136 mm Hg
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu\neq[/tex] 136 mm Hg
In this context type I error is rejecting that the μ is equal to 136 mm Hg when in fact μ is equal to 136 mm Hg.
Step-by-step explanation:
We are given that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 136 mm Hg, which is the value reported in a possibly outdated journal article.
He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 126 mm Hg and the standard deviation of the sample to be 18 mm Hg.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 136 mm Hg {means that the mean systolic blood pressure, μ, of CEOs of major corporations is 136 mm Hg}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu\neq[/tex] 136 mm Hg {means that the mean systolic blood pressure, μ, of CEOs of major corporations is 136 mm Hg}
Type I error states that the null hypothesis is rejected when in fact the null hypothesis was true. So, in this context type I error is rejecting that the μ is equal to 136 mm Hg when in fact μ is equal to 136 mm Hg.
Suppose the researcher decides not to reject the null hypothesis. It means the researcher is making a type I error.
