9) 40
Answer: For example the first one is |-2| is 2.
Step-by-step explanation:
the answer to number 1 is 2 because the absolute value is the same a multiplicative inverse and both means the opposite of a number. So |-5| is still equal to the positive version of the number 5.
Michael is building a fence around his garden to keep the rabbits out. The perimeter of his garden is 42 feet. If the length of the garden is 5 more than the width, what are the dimensions of the fence? Hint: draw a rectangle, and label all 4 sides for the length and width, given what you know.
*Show your work on paper!
a.) Write an equation to represent the situation.
b.) Solve your equation WITH units - you need to find the length AND the width.
Answers
Answer:
a)
perimeter = 42 feet
let the width = y
let the length = 5+y
( the length is 5+y because it is 5 more than the width )
2(5+y)+2y=42
b)
2(5+y)+2y=42
10+2y+2y=42
4y=32
y=8
width = y
= 8
length = 5+y
= 5+8
= 13

- In the algebraic expression x + y, x and y are terms.
・Example:
- The expression x + y - 7 has 3 terms, x, y, and 7. x and y are variable terms; their values vary as x and y vary. 7 is a constant term; 7 is always 7.

Two students are comparing scientific experiments to investigations. They came up with the following ideas.
Student A: Testing plant growth in different types of soils
Student B: Comparing the water level in a lake during different times of the year Which student gave an example of a scientific experiment? (5 points)
A: Student A because it requires experimental and control groups
B; Student B because it requires a hypothesis
C: Student A because it is preferably done in natural settings
D: Student B because it is preferably done across a long period of time
Answers
Answer:
A is the correct answer.
Step-by-step explanation:
In experiment we require a controlled variable which is the constant in example A that is the plant we intend to put into the soil. In example B there's no such thing as controlled variable, so we can't expect the position of the water level. the water level is so unpredictable since tides or tsunami might change the result.
Answer:
A
Step-by-step explanation:
Scientific experiments need to have an independent and a dependent variable. Scientists can manipulate the independent variable. A should be the correct answer because it mentions what I just said. All scientific experiments need to have a control and experimental group. Therefore, student A and the answer A are correct.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
Find the value of x please :)
Answers
Answer:
32 degrees
Step-by-step explanation:
The sum of all angles in a triangle is 180 degrees.
A right angle (The one marked by a small square on the bottom left) measures 90 degrees.
You're given that the other two angles in the triangle measure 58 and x degrees.
To find x, we'll find the sum of all angles, and equate it to 180.
The sum of all angles = 90 + 58 + x = 148 + x degrees
\(148 + x = 180 \text{ // -148}\\\cancel{148 -148} + x = 180 - 148\\x = 32^{\circ}\)

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.
A Ferris wheel has an area of 50 square meters. Find
the radius of the Ferris wheel to the nearest meters.
Round the answer to the nearest whole meter.
Answers
Answer:
19.7 m
Step-by-step explanation:
Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.
Hypotenuse is 10.2 m (radius of circle)
The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees
sin 40 degrees=rise /radius=rise/10.2
sin 40=0.6428=rise/10.2
rise=10.2(0.6428)
rise=6.6 m
13.1+6.6=19.7 m
The radius of the Ferris wheel to the nearest meters will be 4 meters.
What is the area of the circle?It is the close curve of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
A Ferris wheel has an area of 50 square meters. Then the radius is calculated as,
πr² = 50
r² = 15.915
r = 3.989
r ≈ 4 meters
The radius of the Ferris wheel to the nearest meters will be 4 meters.

Six years ago, I was half as old as I will be four years from now. How old will I be five years from now? PLEASE
Answers
Answer: 21
Explanation:
We start by trying to figure out what age you were to start.
We represent your current age with x. So the question now reads:
x-6=(x+4)1/2
We simplify each side with distributive property.
x-6=1/2x +2
subtract 1/2x from each side to isolate the variable. And add 6 to each side
1/2x=8
Multiply each side by 2
x=16
Therefore you are currently sixteen and "five years from now" you will be 21.

A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?
Answers
A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.
How to solveTo solve this problem, we can use the following equation:
total weight / number of bags = weight of each bag
In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:
1.5 pounds / 6 bags = 0.25 pounds per bag
Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.
