Answer:
if 2 length + 2 width is the perimeter, then 2(L+W)=P. if w is 1/3 of L, then W=1/3L, and from there we work back. half of 48 for just one length and one width, we have 24. we want one-third of length+length, so 4 parts. we are left with L=18 and W=6. 18+6=24, x 2= 48. I'm sorry if this was confusing, but I hope this helps!
Please help! Thankss!! :)

An airline ticket costs $40.
The price is increased by 200%.
Work out the absolute increase.
An airline ticket costs $40. The price is increased by 200 percent. The absolute increase is $80.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Cost of airline ticket = $40.
Increase in price = 200% of $40
Absolute increase = [tex]\frac{200}{100}* 40 = 80[/tex]

SSSI WILL GIVE BRIANLISTSActivity Thinking About Circles Around You Do this activity together to investigate circles in the real world. Have you ever wondered why runners start at different spots on a track instead of lining up together? This is called a staggered start. Sincetrac Since tracks have semicircles (or half circles) on the ends, if all the runners lined up together, runners in outer lanes would need to run farther than runners in inner lanes. Why? Because the circumference of the outer lane is greater than the circumference of the inner lane. Staggering starting positions ensures that all runners run the same distance! ? Where do you see circles and semicircles in the world around you? Why could finding the area or circumference be helpful?
Answer:
Step-by-step explanation:
1) The sun, the moon, windows, drawings, this: . And much more…
2) For example, how far you have to walk around a track, how big the moon is, how much ribbon you need to wrap around a circle present…

If one vertex of a slope triangle is at (0,0), the other vertex on the line will be the point that represents the simplified unit rate or slope
The point on the line where the simplified unit rate or slope is True will be the opposite vertex of a slope triangle if one vertex is at (0,0).
Explain about the Slope triangle?A slope triangle is a hypothetical triangle that aids in determining a line's or line segment's slope. The line whose slope you are interested in learning is the triangle's hypotenuse (the diagonal). The "rise" and "run" terms used in the slope formula are the two "legs" of the triangle. Rise/run is a slope.
The slope of a triangle with a slope is positive if the hypotenuse slopes uphill from left to right. The slope of a slope triangle is negative if the hypotenuse slopes downward from left to right.
This is the Greek letter delta, which stands for change. It can be applied to math or simply to make a statement shorter.

ΔABC is equilateral since all sides marked as congruent. Therefore:
m∠ABC = 60°ΔCDE is isosceles since two sides marked as congruent:
m∠DCE = m∠DEC = 1/2(180° - 50°) = 1/2(130°) = 65°∠DEF forms a linear pair with ∠DEC, so they sum to 180°:

Juan rolls a number cube 40 times, he rolls a 3 on the number cube 6 times. What is the experimental probability that he rolls a 3?
Answer: 6/40 = 3/20
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:
P= Time the event occurs/ Total number of trials
In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40
because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6
because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40

A square tile has a width of 1/4 foot. How many tiles will fit end-to-end along a 4-foot wall?
Answer:
16 tiles
Step-by-step explanation:
If the tile is a 1/4 foot wide, then 4 will fit in a foot, and if theres 4 feet to fill, 16 tiles will fit.
If you wanted to write an equation to solve it:
[tex]\frac{1}{4}x=4[/tex]
where x is the number of tiles that will fit. This equation reads "1/4 foot times the number of tiles = 4 feet"
[tex]\frac{x}{4} =4\\x=4\times4\\x=16[/tex]
15 crates of egg cost 4500 how many crates will 1500 buy
Answer:
5 crates
Step-by-step explanation:
1500/4500 = 1/3
1500 is 1/3 of 4500, so 1500 buys 1/3 of 4500.
1/3 * 15 crates = 5 crates
Answer: 5 crates
Answer:
3 crates for $1,500
Step-by-step explanation:
15 is to x as 4500 is to 1500, or 15 is to x as 3 is to 1. Then x = 3 (crates)
what year was it, exactly 4 centuries before 1965?
Based on the number of years in a century, we can calculate that the 4 centuries before 1965 was 1565.
A century refers to a period of 100 years.
If we are looking for a period of 4 centuries therefore, this would be:
= 4 x 100
= 400 years
4 centuries before 1965 would therefore be:
= 1965 - 400
= 1565
In conclusion, the answer is 1565.

how many boxes should show on grid for 3/8=18 eggs
The number of box is an illustration of proportions
8 boxes must be shown on the grid
The proportion is given as:
[tex]\mathbf{\frac{3}{8} = 18\ eggs}[/tex]
The above proportion means that:
3/8 of the total number of eggs is 18
Let the total number of eggs, be x
So, we have:
[tex]\mathbf{\frac{3}{8} \times x= 18\ eggs}[/tex]
Express 3/8 as a decimal
[tex]\mathbf{0.375 \times x= 18\ eggs}[/tex]
Divide both sides by 0.375
[tex]\mathbf{x= \frac{18}{0.375 }\ eggs}[/tex]
[tex]\mathbf{x= 48\ eggs}[/tex]
This means that, the total number of eggs is 48, and 8 boxes must be shown on the grid
