Raul calculated that he would spend $125 on school supplies this year. He actually spent $87.50 on school supplies. What is Raul’s percent of error?

A: 42.9%

B: 37.5%

C: 30%

D: 3%

Answers

Answer 1
C - 30%.

We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error. 

So it would be:

87.5/ 125 = 0.7

And 1-0.7 = 0.3 

When we move the chemical place two places to the left to make it a percentage, it will become 30%. 
Answer 2

Answer:

42.9

Yolanda and her 3 brothers shared a box of 156 toy dinosaurs. About how many Dino's did each child get?

Answers

Final answer:

Yolanda and her 3 brothers are sharing 156 toy dinosaurs. By dividing 156 by the total number of children, which is 4, we find that each child gets 39 toy dinosaurs.

Explanation:

The question requires us to divide a certain number of items, specifically toy dinosaurs, equally among a group of children. Yolanda and her 3 brothers share a total of 156 toy dinosaurs. To find out how many dinosaurs each child gets, we need to perform a simple division operation.

Since there are 4 children in total (Yolanda plus her 3 brothers), we divide the total number of toy dinosaurs by 4:

156 toy dinosaurs ÷ 4 children = 39 toy dinosaurs per child

Therefore, each child would receive approximately 39 toy dinosaurs.

Final answer:

To determine how many toy dinosaurs each child receives, divide 156 (the total number of dinosaurs) by 4 (the number of children), resulting in 39 dinosaurs per child.

Explanation:

The subject of this question is Mathematics, and it belongs to the Middle School grade level. The question involves dividing a set of items equally among a group of children, which is a basic arithmetic problem.

Yolanda and her 3 brothers together make a group of 4 children. To find out how many toy dinosaurs each child gets, we divide the total number of toy dinosaurs by the number of children:

Total number of toy dinosaurs: 156
Number of children: 4

Number of dinosaurs per child = 156 ÷ 4
= 39

So, each child would receive approximately 39 toy dinosaurs.

What is the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4)?
A. y−4=−1/5(x+8)
B. y+4=−9/11(x−8)
C. y−4=−9/11(x+8)
D. y+4=−1/5(x−8)

Answers

Answer:

C. [tex]y-4=-\frac{9}{11}(x+8)[/tex]

Step-by-step explanation:

The point slope form is  [tex]y-y_1=m(x-x_1)[/tex] where m is the slope,

First we are going to calculate [tex]m[/tex]:

If you have two points:

[tex]A=(x_1,y_1)\\B=(x_2,y_2)[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

In this case: A=(-8,4) and B=(3,-5)

[tex]x_1=-8, y_1=4\\x_2=3, y_2=-5[/tex]

Replacing in the formula:

[tex]m=\frac{-5-4}{3-(-8)}=-\frac{9}{11}[/tex]

Then [tex]y-y_1=-\frac{9}{11}(x-x_1)[/tex],

Now we have to replace with: [tex]x_1=-8, y_1=4[/tex],

[tex]y-y_1=-\frac{9}{11}(x-x_1)\\\\y-4=-\frac{9}{11}(x-(-8))\\\\y-4=-\frac{9}{11}(x+8)[/tex]

Then the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) is:

C. [tex]y-4=-\frac{9}{11}(x+8)[/tex]

Kathleen studied 2/3 of the night's in the month. If the month has 30 days, how many nights did she study?

Answers

This is a proportion problem.
2/3= x/30
Cross multiply and divide
30 x2= 60
60 divided by 3 is 20
Answer is 20


Ps: you could also find the answer by dividing 30 by 3 and that's how you get 1/3 of 3 which is 10. So 2/3 is just 10 + 10= 20

The number of nights studies in a month is 20.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Number of nights in a month = 30

The number of nights studied in a month.

= 2/3 x 20

= 2 x 10

= 20

Thus,

The number of nights is 20.

A square room has a tiled floor with 81 square tiles. How many tiles are along an edge of the room?

Answers

As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.

There are 9 tiles are along an edge of the room.

Here,

A square room has a tiled floor with 81 square tiles.

What is Area of a square?

In square all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side.

Now,

A square room has a tiled floor with 81 square tiles.

Number of tiles on edge of the room is equal to length of one side of the room.

Hence, we have to find the length of each side of a square room.

For this,

Area of square room = [tex]side^{2}[/tex] = [tex]81[/tex]

⇒ side = √81 = 9

So, There are 9 tiles are along an edge of the room.

Chris wants to leave a 15% tip on the price of the food, calculated before sales tax. What is the maximum cost of food the group can order and not go over $63? Help Please

Answers

Well there is two ways that you an solve this equation. So I will tell you both and you can pick which one you prefer to use. Anyone is fine by me not that it really matters but anyways here it goes.

First way is... You want to find out what 15% off $63 so a way to do it is you first want to find out what 10% of $63 is which would be 6.3 because you jus have to move the decimal place to the left one place. Which leaves you with the left over 5% which is half of the 10% which we have got 6.3 so half of that would be 3.15. So add those together and you get 9.45. I hope this is what you wanted to know.

Just because!!!

The other way that you could have done it is that you could have done it the decimal way... $63x0.15 to get  9.45 the same answer as above.

f(x)=x^2-x-1 , average rate of change of f over interval -1 greater than or equal to x less than or equal to 1

Answers

To start, calculate your endpoints of your interval. Do this by plugging in your limits on x, -1 and 1, into your function. This gives you f(-1)=(-1)^2-(-1)-1=1+1-1=1 and f(1)=1^2-1-1=-1. Now, use your two endpoints, (-1,1) and (1,-1), and use the formula for slope, [tex]m= \frac{y_2-y_1}{x_2-x_1} [/tex]. This gives you [tex]m= \frac{-1-1}{1-(-1)} = \frac{-2}{2} =-1[/tex]. This means your average rate of change is -1.
Final answer:

The average rate of change of the function f(x)=x^2-x-1 over the interval from -1 to 1 is calculated as the change in the function's values over the change in x, which results in -1.

Explanation:

The average rate of change of a function f(x) over a given interval [a, b] is defined as the change in f(x) divided by the change in x. It is equal to the value of the function at point b minus the value of the function at point a, divided by (b-a).

For the function f(x)=x^2-x-1, we are given the interval from -1 to 1. In this case, a=-1 and b=1.

So first calculate f(a) and f(b), i.e., f(-1) = (-1)^2 -(-1)-1 = 1, and f(1) = (1)^2 -(1)-1 = -1.

Then, plug these values into the average rate of change formula, which gives us (-1-1) / (1 - (-1)) = -2 / 2 = -1. So the average rate of change of the function f over the interval from -1 to 1 is -1.
