Answer:
The investment cost from ice cream is significantly smaller than the hot dog shop, the man could perhaps opt for something like a hot dog stall.
Step-by-step explanation:
The given values are:
Percentage of being hot summer,
= 40%
i.e,
= 0.4
So that,
The percentage of being cold,
= 1 - 0.4
= 60%
Now,
From hot dog, the expected profit will be:
⇒ [tex]5000\times P(cold \ summer) + 1000\times P(hot \ summer)[/tex]
On putting the values, we get
⇒ [tex]5000\times 0.6+1000\times 0.4[/tex]
⇒ [tex]3400[/tex]
From ice-cream stall, the profit will be:
⇒ [tex]6500\times P(hot \ summer)+1000\times P(cold \ summer)[/tex]
On putting the values, we get
⇒ [tex]6500\times 0.4+1000\times 0.6[/tex]
⇒ [tex]3200[/tex]
So the above is the right response.
Last year, Jackson made 24 one-cup servings of chili for a school party. This year, he will make ten times the amount of chili that he made last year. If there are 4 cups in 1 quart and 4 quarts in one gallon, how many gallons of chili will Jackson make this year?
Answer: 15
Step-by-step explanation:
You have to multiply what Jackson made last year (24 cups) times 10 which equals 240. after that you do 240 divided by 4, which equals 60, and 60 divided by 4 again, which gives us the answer (15) (hope you could understand that) Also sorry for not answering in time!

9. Find a and the length all sides.
Answer:
a = 8
Bottom and top length are 68
left and right are 28
Step-by-step explanation:
6a + 20 = a + 60 (same length do to the little tick marks)
5a = 40 (subtract 1a from both sides and 20 from both sides)
a = 8 (Divide)
Answer: A = 8
Step-by-step explanation:
Since Side BC and AD are equal
then we can plug both equations to each other to find A
6a + 20 = a + 60
solve it
6a + 20 = a + 60
- 20 -20
6a = a + 40
-a -a
5a = 40
a = 8
You can now find the length of all sides :)

Blake must choose between two job offer. Evergreen Landscape will pay him $9.75 hours to mow lawns, but its is a long way from his house. He would probably spend $25 per week on gas. Just Jean will pay Blake $6.50 per hour to work as a retail clerk. Since the store is very close to his house, he would probably only spend $5 per week on gas. let x be the number of hours that Blake will work in a week and y be the amount of money he will have end of the week if he does not spend any money expect on gas.
a. Explain how the following two rules reflect the two jobs offer that Blake has.
B. Solve the system of equations in part A. (9.75x - 25 = 6.50x -5) indicates what its tell you about blake job offers and the amount of money he will have at the end of the week.
C. blake plan to work at least 15 hours per week. Which job should he take.
Answer:
A. The explanation of the rules are;
For the job offer for the Evergreen Landscape, Blake will have 9.75 times by the number of hours worked less the $25 for gas at the end of the week
For the job offer for the Just Jean, Blake will have 6.50 multiplied by the number of hours worked less the $5 for gas at the end of the week
B. The solution to the equations is that the number of hours Blake will work to have the same amount in both Jobs is 6.1538 hours
C. Blake should take the Job at Evergreen Landscape
Step-by-step explanation:
The amount Evergreen Landscape will pay Blake to mow lawn = $9.75
The amount Blake would spend to work per week on gas for work at Evergreen Landscape = $25
The amount Just Jean will pay Blake to work per week as a retail clerk = $6.50
The amount Blake would spend to work per week on gas for work at Just Jean = $5
Whereby, x = The number of hours that Blake will work in a week
y = The amount of money he will have end of the week, if he does not spend any money except gas
A. The given rules are;
y = 9.75·x - 25
y = 6.50·x - 5
For the job offer for the Evergreen Landscape, we have;
y = 9.75·x - 25
Blake has to put aside $25 out of his weekly earnings for gas
Blake will have 9.75 multiplied by the number of hours worked less the $25 for gas
For the job offer for the Just Jean, we have;
y = 6.50·x - 5
Blake will have 6.50 multiplied by the number of hours worked less the $5 for gas
B. The common solution of the both equations is given by equating both values of y as follows;
9.75·x - 25 = 6.50·x - 5
9.75·x - 6.50·x = 25 - 5
3.25·x = 20
x = 20/3.25 = 6.15385
x = 6.15385
The number of hours Blake will work to have the same amount in both Jobs = 6.1538 hours
C. Given that the number of hours Blake can work each week = 15 hours, we have;
For the job offer for the Evergreen Landscape, we have;
y = 9.75 × 15 - 25 = 121.25
The amount of money he will have end of the week = y = $121.5
y = 6.50 × 15 - 5 = 92.5
The amount of money he will have end of the week = y = $92.5
Therefore, given that by working 15 hours a week, Blake earns $121.5 on the Evergreen Landscape job and $92.5 on the Just Jean job, Blake should take the Job at Evergreen Landscape.

Chase lives 1 and one half blocks west of Ellie. They draw a number line to model this situation. Because Ellie lives 1 and three fifths blocks east of school, they give her house the coordinate 1 and three fifths . Chase incorrectly claims that the coordinate of his house is 3 and one tenth . What is the correct coordinate of Chase's house? What is Chase's likely error?
Answer:
1/10
Step-by-step explanation:
A number line is a line which contains numbers marked at intervals (usually regular intervals). Points to the right of the origin are positive numbers while those to the left are negative numbers.
The school is used as the origin. Ellie house is 1 and three fifths blocks east (to the right) of the school. This means that it is + 1 and three fifths (+8/5).
Chase house is 1 and one half blocks (3/2) west of Ellie. Since it is west then it is to the left. Hence the coordinate of chase house = 8/5 - 3/2 = 1/10
Hence the coordinate of chase house is 1/10(one tenths).
The error may be as a result of thinking chase house is to the east of Ellie, hence adding to get 3 and one tenth.

Answer:
60 degrees
Step-by-step explanation:
1. Find angle t. A and T are supplementary angles so both added together should equal 180. 180 - 120 = 60. Angle t is 60 degrees
2. All three angles inside the triangle should add up to 180 degrees. 60 +60 = 120 and 180 - 120 = 60. Angle s is also 60 degrees

solve the proportion 4/(x+1) = 3/(x+2)
Answer:
x = -5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
4/(x + 1) = 3/(x + 2)
Step 2: Solve for x
Cross multiply: 4(x + 2) = 3(x + 1)Distribute: 4x + 8 = 3x + 3Subtract 3x on both sides: x + 8 = 3Subtract 8 on both sides: x = -5Answer:
to solve a proportion, you cross multiply. so you take the numerator of the first one, and multiply it by the denominator of the second one. and then the denominator of the first one is multiplied by the numerator of the second one:
4(x+2)=3(x+1) (set them = and then use the distributive property)
4x+8 = 3x+3 (subtract 3x from both sides)
x +8 = 3 (subtract 8 from both sides)
x= -5 (the answer)

A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each T-shirt printed with your design costs an additional $8.
A. write a linear model that represents the Total cost of purchasing your team's T-shirt with your design as a function of the number of T-shirts.
B. your team has 35 members. If a T-shirt is purshased for every member. what would be the cost?
Answer:
Part A)
[tex]C(t)=25+8t[/tex]
Part B)
[tex]C(35)=\$305[/tex]
Step-by-step explanation:
We will let t represent the total number of t-shirts printed.
We are charged an initial fee of $25. So, for our linear model, our constant is 25. And each t-shirt printed costs an additional $8. So, for t t-shirts, it will cost an additional 8t dollars.
Part A)
So, from the above information, we can write the following function:
[tex]C(t)=25+8t[/tex]
Where C(t) is the total cost for t shirts.
The 25 represents our initial fee and the 8t represents the cost for t t-shirts.
Part B)
So, if we have a team of 35 members, we will need 35 t-shirts.
Then the total cost will be given by:
[tex]\begin{aligned}C(35)&=25+8(35)\\&=25+280\\&=\$305\end{aligned}[/tex]
So, it will cost a total of $305.
