Answer:
n=6
Step-by-step explanation:
n= the amount of boxes he needs
so if he puts 30 toys in each box out of 180 you divide 180 by 30 and you get your answer.
so the amount of boxes he needs = 6
Final answer:
To find the number of boxes needed to pack 180 cat toys with 30 toys in each box, divide the total number of toys by the number of toys per box to get the answer of 6 boxes.
Explanation:
The number of boxes Aroon needs can be calculated by dividing the total number of cat toys by the number of toys packed in each box.
Let n represent the unknown factor, which is the number of boxes he needs.
The equation representing this situation is n = 180 ÷ 30.
Solving n = 6, Aroon needs 6 boxes to pack all 180 cat toys.
12x+7<−11 OR 5x−8>40. Solve for the inequality
To solve the inequality 12x+7<−11 OR 5x−8>40, isolate x in each equation. The solutions are x < -1.5 and x > 9.6.
Explanation:To solve for the inequality 12x+7<−11 OR 5x−8>40, we first need to simplify each equation separately i.e isolate x in each separate equation.
For the inequality 12x + 7 < -11: Subtract 7 from both sides, which gives 12x < -18. Then divide by 12 which will yield x < -1.5.
For the inequality 5x - 8 > 40: Add 8 to both sides, which gives 5x > 48. Then dividing both sides by 5, we get x > 9.6.
Our answer is therefore x < -1.5 OR x > 9.6. This means that any x value satisfying either of these conditions will satisfy the original inequality.

To solve the compound inequality 12x + 7 < -11 OR 5x - 8 > 40, solve each inequality separately to find x < -1.5 or x > 9.6. This means x can be any value less than -1.5 or greater than 9.6.
To solve for x in the given compound inequality, we need to handle each inequality separately.
Step-by-Step Solution:
First, solve the inequality 12x + 7 < -11:Subtract 7 from both sides: 12x < -18Divide both sides by 12: x < -1.5Second, solve the inequality 5x - 8 > 40:Add 8 to both sides: 5x > 48Divide both sides by 5: x > 9.6Therefore, the solution to the compound inequality is x < -1.5 OR x > 9.6.
This means x can be any number less than -1.5 or greater than 9.6.

f(x) = -3x^2+2x-5
What is f(-1)
Answer:
- 10
Step-by-step explanation:
Wherever you see an x, put in a minus 1.
f(-1) = -3(-1)^2 + 2x - 5
f(-1) = -3(1) + 2(-1) - 5
f(-1) = - 3 - 2 - 5
f(-1) = - 10
Felipe won a charity raffle. His prize will be randomly selected from the 9 prizes shown below.
The probability of Felipe winning a specific prize in the charity raffle is 1/9 or approximately 0.111.
Explanation:The subject of the question is Mathematics and the grade level is Middle School.
To determine the probability of Felipe winning a specific prize from the 9 prizes, we need to divide the number of desired outcomes (one specific prize) by the total number of possible outcomes (9 prizes in total). Therefore, the probability of Felipe winning a specific prize is 1/9, or approximately 0.111.
For example, if Felipe wants to calculate the probability of winning the first prize, he has 1 desired outcome (winning the first prize) out of 9 possible outcomes (9 prizes in total). Thus, the probability of winning the first prize is 1/9.

What is the length of DE
The length of DE is 6 inches.
I can see that from the image, DE is a horizontal line segment that is 6 units long. This is because the x-axis is labeled in units, and DE spans 6 units on the x-axis.
we know that
The triangle XYZ and DEF are similar triangles
therefore
The ratio of their corresponding sides is equal
12/8 = 9/x
x = 8 * 9/12
x = 6 Units.
Therefore the length of DE is 6 inches.

-21 = (m/3)
A) m = 7
B) m = -7
C) m = -63
D) m = 63
Answer:
C) m = -63 is your answer
Step-by-step explanation:
Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.
Multiply 3 to both sides
-21 = (m/3)
(-21)(3) = (m/3)(3)
m = (-21)(3)

The sum of three consecutive odd integers is 951 What are the integers
Answer:
315, 317, and 319
Step-by-step explanation:
So first we have to set the equation up. Since it is odd, we would write
[tex](x-2)+x+(x+2)=951[/tex]
where x is the middle integer. This gets you
[tex]3x=951[/tex]
Solving for x we get
[tex]x=317[/tex]
Since x was the middle, we subtract 2 and add 2 and put them together in ascending order, or 315, 317, and 319.
Mark bought a concert ticket for $88, then sold it for $121. By what percent did he mark the ticket up?
Answer:
27.27%
Step-by-step explanation:
Formula:
%= 100*(revenue-cost)/ revenue
%= 100* (121-88)/121
By 27.27% the ticket price mark up.
What is Percentage increase?The ratio of the increased value to the original value, multiplied by 100, is the percentage increase formula. It is outlined as a percentage. Anything's value will increase if it is valued more, so will its proportion.
Given:
Mark bought a concert ticket for $88.
Mark sold it for $121.
Change in amount= 121- 88 = $33.
So, the percent increase
= (121- 88) / 88 x 100
= 33/121 x 100
= 3/11 x 100
= 27.27%

The location of four buildings are on a coordinate grid are as follows: bank at (3, −3) post office at (−2, −3) dry cleaner at (−2, 6) pizza shop at (3, 6) Liza begins at the bank and then walks to the post office, then to the dry cleaner, and then to the pizza shop. Then she walks to the bank again, where she left her cell phone. The path between each building is a straight line. One unit on the coordinate grid equals 400 yards. What is the total distance Liza walked?
Answer:
11,200 yards
Step-by-step explanation:
First, plot all the points on a graph. Then draw Liza's path. Add them all up and multiply by 400.
28 · 400 = 11,200.
Liza walked 11,200 yards.
My graph is attached. The blue line is Liza's path and each coordinate point is labeled.
I hope this helps u!!
:)
Answer:
11,200 yards.
Step-by-step explanation:
Distance between two points is;
Distance = √(x²+y²)
Distance between Bank and post office = √(5²+0)
= 5
Distance between post office and dry cleaner = √(0+9²)
= 9
Distance between Dry cleaner and pizza shop = √(0+5²)
= 5
Distance between Bank and pizza shop = √(9²-0)
= 9
Total distance = 5+9+5+9
= 28 units
1 unit ⇒ 400 yards
28 units ⇒ (28×400)
⇒ 11,200 Units
If two planes intersect, then they intersect in exactly one point. True or false?
Answer: False
A plane is a flat line that extends forever in all directions. Think of a flat piece of paper that does not bend or curve. If you intersect two planes, then they will form a straight line. This line will extend forever both directions. There are infinitely many points on this line of intersection. You can think of a book as a good example: the pages are the planes while the spine is the line of intersection.

7.10
The cost c of one baseball if, baseball bat and 8 baseballs cost $163.25, and the bat cost $106.45 is $11.36.
What is the equation?It is a mathematical statement that says, "this is equivalent to that," in other words. There appears to be an equal sign in the middle, a mathematical expression on the right, and a mathematical expression on the left.
Given:
The total cost of a baseball bat and 8 baseballs cost is $163.25,
The cost of one bat is $106.45,
Write the equation for the statement as shown below,
106.45 × 1 + 8c = 163.25
Here c is the cost of one baseball,
Solve the above equation as shown below,
106.45 + 8c = 163.25
8c = 163.25 - 106.45
c = 56.8 / 8
c = 11.36
Thus, the cost of one baseball is $11.36.

( 4 over 4 )x = 4/32 what is the value of x
4 over 4 (4/4) is equal to 1.
The equation can be rewritten as X = 4/32
4/32 can be simplified to 1/8
So you have X = 1/8
Answer:
1/8
Step-by-step explanation:
to simplify 4/32, you just have to see how many times 4 goes into 32, in this case the answer is 8. A good rule of thumb is if the smaller number is on the top of the fraction, you will get a fraction for an answer, so the 4 turns into 1 and the 32 turns into 8.

So, 7=3*5+b
7=15+b
b = -8
