HELPAlicia estimated her test score to be 85. Her actual score was 80. What was the percent error in Alicia’s estimate? Round your answer to the nearest tenth of a percent.

Answers

Answer 1

Answer: first find the difference so:
85 - 80 = 5
now find what percentage of 80 is 5
5/80 = 0.0625
so 6.25% or in your case 6.3%

Mrs. Fisher has 91 watches at her store. She says she can put them into rows and columns without any watches leftover. Mr. Fisher says that she can only put them into one row. Who is correct, and why? (Working with prime and composites)

Answers

Mrs. Fisher's claim is correct, and Mr. Fisher's claim is incorrect

The number of watches is given as:

$n = 91$

91 can be expressed as the product of 7 and 13.

So, we have:

$n = 7 * 13$

This means that:

The 91 watches can be put in 7 rows and 13 columns or 7 columns and 13 rows.

Hence, Mrs. Fisher's claim is correct.

This is a question of whether 91 is a prime number or not. And it is not so Mrs. Fisher is right, you can arrange them in 7 rows and 19 columns or vice versa. 7 and 9 are factors of 91.

Which of the following is a point slope equation of a line that passes through the points

Answers

For this case we have that the slope of a line is given by:

$m = \frac {y2-y1} {x2-x1}$

If we have the points:

$(-1,4)\n(8, -2)\nm = \frac {-2-4} {8 - (- 1)}\nm = \frac {-6} {9}\nm = - \frac {2} {3}\n$

Thus, the equation is of the form:

$y-y_ {0} = - \frac {2} {3} (x-x_ {0})$

Substituting any of the points we have:

$y-4 = - \frac {2} {3} (x - (- 1))\ny-4 = - \frac {2} {3} (x + 1)$

Answer:

Option D

Answer:

Choice D is the answer.

Step-by-step explanation:

We have given two points.

Let (x₁,y₁) = (-1,4) and (x₂,y₂) = (8,-2)

We have to find the point-slope form of the line that passes through the given points.

y-y₁ = m(x-x₁) is point-slope form of the line that passes through the points.

m is slope of line.

m = y₂-y₁ / x₂-x₁

Putting values in above formula , we have

m = -2-4 / 8-(-1)

m = -6 / 9

m = -2/3

Putting values of slope and using a point , we have

y-4 = -2/3(x-(-1))

y-4 = -2/3(x+1) is point-slope form of line that passes through the points (-1,4) and (8,-2).

Something times 2 equals 36

Answers

18 is the answer
and i am just typing so i can submit

Something times 2 equals 36

now let say that X is the number missing

Replace x by something

x*2-36

2x=36

Divide both sides by 2

x= 18

I hope that's help :)

another way you can do that is to divide 36 by 2 and it will be 18

I hope that's help and if you have questions please ask ;)

A grocery store sells 6 bottles of water for $4 and 18 bottles of water for $10. Is the cost of the water proportional to the number sold? EXPLAIN.

Answers

The answer is "No", the cost of water is not proportional to the number of sold.

What is the ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.

As per the given information in the question,

The cost of 6 bottles of water is $4.

Then, the price of each bottle will be,

= $4/6 = $0.66

The next condition is,

The cost of 18 bottles of water is $10

Then, the price of each bottle will be,

= $10/18 = $0.55

Comparing both the values, the ratio is not the same.

No, because if it were proportional the cost for 18 bottles of water would be $12

Sarah started with 50 dollars in her bank account. Each month, she puts 25 more dollars in her account. The amount of money in dollars D in her account is given by D = 25m + 50 where m is the number of months she has added 25 dollars to her account.How much money will be in Sarah’s account after 8 months?

A.
$82

B.
$200

C.
$250

D.
$300

Answers

D=25m+50

D=(25)(8)+50

D=200+50

D=250

There will be $250 after 8 months.

The answer is C.$250
