Assuming both people are pulling in the same direction, the net force on the car is, according to Newton's second law,
600 N + 800 N - 1200 N = (2250 kg) a
Solve for the acceleration a :
200 N = (2250 kg) a
a = (200 N) / (2250 kg)
a ≈ 0.0889 m/s/s
Dani decides to add the cost of each shirt and the cost of each bag together, and then multiply by seven to find the total cost. Write an algebraic expression for the total cost of the gifts using Dani’s method. Remember, use t and b as your variables. (3 points)
Answer:
Total cost of 7 pair = 7(t + b)
Step-by-step explanation:
Given:
Cost of each shirt = t
Cost of each bag = b
Number of pair = 7
Find:
Total cost
Computation:
Total cost of each pair = t + b
Total cost of 7 pair = 7(t + b)

A rental company charges $70 a day and 20 cents a mile for renting a truck. Michael rents a truck for 3 days, and his bill came to $295. How many miles did he drive?
Michael drove 1125 miles and paid $295 for renting the truck for 3 days
Rental company charges per day = $70
Rental company charges per mile = $0.20
Number of days truck is rented by Michael = 3 days
The total amount paid by Michael for the truck = $295
Let x be the number of miles Michael drives the truck
Formulating the equation using the information given in the question:
295 = 70 + 0.20(x)
295-70 = 0.20(x)
225 = 0.20(x)
x = 1125 miles
Therefore, the total miles driven by Michael is 1125 miles.
Michael paid $295 for driving the truck for 1125 miles and renting it for 3 days.

Answer:
Company B would be a better choice.
Company B is cheaper.
Step-by-step explanation:
Let x be the rate per square foot
✔️Company A charges: $215 + $0.50x
If they are installing 400 ft² of carpet, they would be charged the following by company A,
Substitute x = 400 into the equation.
We have:
$215 + $0.50(400) = $415
They would pay $415 if they use Company A's services
✔️Company B charges: $100 + $0.75x
If they are installing 400 ft² of carpet, they would be charged the following by company B,
Substitute x = 400 into the equation.
We have:
$100 + $0.75(400) = $400
They would pay $400 if they use Company B's services .
✅Company B would be a better choice because the total charges they would pay to install 400 ft² carpet is cheaper than they would pay for Company A.

1084 - 1018
(6+5)6
Answer:
5 + 1(22-10)
Step-by-step explanation:
3 × 22 = 66
5 + 1(22-10) =5(12) = 60
6 × 7 + 8 × 3 = 42 + 24 = 66
1084 - 1018 = 66
(6 + 5)6 = (11)6 = 66
Answer:
5 + 1(22-10)
Step-by-step explanation:
First we need to solve for 11(7-1). Since the 7 - 1 is in the parenthesis it is what you do first. We know 7 - 1 equals 6. Since we got 6 as our answer for 7 - 1 we would take the 6 and multiply it with the 11 in the equation 11(7-1). If we would multiply 6 x 11 we would have an answer of 66.
Now we need solve each equation to see which one doesn't equal 66.
3 x 22 = 66 therefore it wouldn't be our answer.
5 + 1(22-10), we should always remember that we solve the equation with the parenthesis first. So if we would solve 22 - 10 we would get 12. Next we need to solve 5 + 1 and we should know this equals to 6. Now since we have our answer to both equation we would need to add 12 + 5 If we added those two number we'd get 17. There this would be our ANSWER.
6 x 7 + 8 x 3, we'll need to multiply 6 x 7 and then 8 x 3 after we get our answers to those equations we would need to add them and see if we would get 66 or not. So first I would multiply 6 x 7 and when I multiplied it I got 42. Next we would multiply 8 x 3 and that would equal 24. Now we need to ad 42 + 24. When we add 42 + 24 we get the answer of 66. Therefore this wouldn't be our answer.
1084 - 1018, this one would be easy to solve so we would nee to solve 1,084 - 1,018. If you don't know how to solve that it's okay! We can do it together. So if you write it in a paper or on something you could write it like I'll use a board. You would need to have 1,084 written in the top because that's the biggest number and 1,018 in the bottom because that a smaller number then 1,084. So we would nee to solve the one's place first. We wouldn't be able to solve 4 - 8 so we need to go over to the tens place and take from there now since we took from the 8 it'd become 7 and now the 4 is 14. So we'd do 14 - 8 for the ones place and we have our answer as 6. Now we need to solve the tens place 7 - 1 we know that equals 6 so we need to put 6 under our tens place. Next we go to the hundred place and do 0 - 0 and that's really easy haha it'd equal 0. So under the hundred place we can put 0 or leave it blank I left mines blank. Now finally we would do 1 - 1 and we know that equals 0 as well. So we can put 0 under our thousand place or leave it blank, I left it blank. Therefore this equals 66 so this wouldn't be our answer. Below in the picture I showed my work. :)
(6+5)6, first we do what's in the parenthesis. Which is 6 + 5 that'd equal 11. So since now we have 11 as our answer for 6 + 5 we'd need to do 11 x 6 and that would equal 66. Therefore our answer for this equation would be 66 so it wouldn't be our answer..

Bob's average golf score at his local course is 93.6 from a random sample of 34 rounds of golf. Assume that the population standard deviation for his golf score is 4.2. The 90% confidence interval around this sample mean is:_______.
a. (92.4, 94.8).
b. (89.0, 98.3).
c. (90.5, 96.7).
d. (93.2, 94.0).
Answer:
a. (92.4, 94.8)
Step-by-step explanation:
Given that:
Mean (m) = 93.6
Standard deviation (σ) = 4.2
Sample size (n) = 34
α = 90%
Confidence interval around sample mean :
Mean ± Zstatistic * s/√n
Z0.90 = 1.645 (Z probability calculator)
s / √n = 4.2 / √34 = 0.7202940
Lower limit = 93.6 - (1.645 * 0.7202940) = 92.41511637 = 92.4
Upper limit = 93.6 + (1.645 * 0.7202940) = 94.78488363 = 94.8
A student graphs 5x−y=7 on a coordinate plane. Which equation, when graphed on the same coordinate plane, will result in a system of equations with no solution? 5x−y=7 5 x − − y = 7 5x−y=1 5 x − − y = 1 x−5y=35 x − − 5 y = 35 x−5y=5
Answer:
5x−y=1
Step-by-step explanation:
An equation is a statement that shows the equality between two expressions.
An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.
The equation after it is simplified would have the same coefficients and different constant.
Given:
5x−y=7
An equation that will result in a system of equations with no solution will have the same coefficient but different constant.
Hence 5x−y=1, would give a system of equations with no solution.
Simplifying gives:
7 = 1 (no solution)
3. Two balls are drawn in succession without replacement from an urn containing 4 red balls and 3 blue balls. Find the probability mass function (P.M.F.) for the number of red balls draw.
Answer:
X ____ 0 ______ 1 _______ 2
P(x) __ 1/7 _____ 4/7 _____ 2/7
Step-by-step explanation:
Given that :
Number of red balls = 4
Number of Blue balls = 3
Total number of balls = (4 + 3) = 7
Picking without replacement :
Number of picks = 2
1st pick is red :
Probability = (required outcome / Total possible outcomes)
USing combination formula :
nCr = n! / (n-r)! r!
Total possible outcome :
7C2 = 7! / 5!2! = 7*6 / 2 = 42 / 2 = 21
X = number of red
For red = 0;
P(x =0) = required outcome / Total possible outcomes
P(x = 0)
Required outcome : [4C0 * 3C2)]
P(x = 0) = [(4C0 * 3C2)] / 21 = (1*3)/21 = 3/21 = 1/7
P(x = 1)
Required outcome : [4C1 * 3C1)]
P(x = 1) = [(4C1 * 3C1)] / 21 = (4*3)/21 = 12/21 = 4/7
P(x = 2)
Required outcome : [4C2 * 3C0)]
P(x = 2) = [(4C2 * 3C0)] / 21 = (6*1)/21 = 6/21 = 2/7
Hence ;
X ____ 0 ______ 1 _______ 2
P(x) __ 1/7 _____ 4/7 _____ 2/7
