(50 points) If the area of the rectangle shown is 88 square inches, which equation could be used to find the value of x?
Answer:
x=3
Step-by-step explanation:
Point p is located in the first quadrant of a coordinate plane.If p is reflected across to form p',choose the four statements that will always be true.
Answer:
When we do a reflection of a point (x, y) about a given line, the distance between the point (x, y) and the line is invariant under the transformation.
In the case of reflection over x-axis we have:
T (x, y) => (x, -y)
In the case of reflection over the y-axis, we have:
T (x, y) => (-x, y)
Because these two lines are perpendicular, a reflection over the x-axis leaves the distance between the point and the y-axis invariant (and the same for the inverse case)
Then 4 statements that will always be true:
1) The distance between p' and the x-axis is the same as the distance between p and the x-axis.
2) The distance between p' and the y-axis is the same as the distance between p and the y-axis.
From 1 and 2, we get:
3) The distance between p' and the origin is the same as the distance between p and the origin.
4) As we have a reflection, p' can not be in the same quadrant than p, then p' can not lie on the first quadrant.

PLEASE HELP ME RIGHT ANSWERS ONLY Your gas-powered weed trimer has a tank that holds 0.72 gallons. If you burn 0.13 gallons every time you trim around your house, how many times can you trim the weeds without refilling the tank?
Answer:
5 times
Step-by-step explanation:
The tank holds 0.72 gallons, and burn 13 gallons every time. Which means 0.72 divided by 0.13 would be the amount of times you would trim the weeds without refilling the tank. Which in this case the answer is 5.538... so if you round it u would get 5.

Tip #1: Find the right string trimmer for you.
A few different string trimmers exist to meet the needs of you and your lawn:
Electric string trimmers tend to use lithium-ion batteries at 40 to 80 volts and are clean, quiet, and light. The uncorded versions add mobility to your work; however, corded electric string trimmers don’t require recharge time and are lighter.
Gas string trimmers use gas engines that provide more power than their electric counterparts. These trimmers are cordless and mobile, but you must regularly refuel for continued use. Some gas trimmers require a pull-start to crank, while other models come with an automatic crank.
String trimmer mowers, or walk-behind trimmers, resemble traditional lawnmowers without the size or the spinning blade. String trimmer mowers offer an in-between range for those lawn sections too big or too small for conventional mowers and trimmers.
Tip #2: Take safety precautions when using your string trimmer.
Like lawnmowers, string trimmers use a spinning motion to cut grass and thin wooden plants. For example, trimmers cutting in a counter clockwise spin will eject cut debris in a leftward direction.
Acknowledge the direction of your string trimmer’s spin and position yourself appropriately to avoid harmful debris hitting your body, like rock, glass, plastic, or any other small objects that can go flying when hit by the trimmer’s filament line. Additionally, keep children and pets indoors, or otherwise keep them and others on the opposite side of the eject direction.
Tip #3: Take advantage of spin direction when using your string trimmer.
Though you must heed the spin direction of your string trimmer for safety, the spin direction also commands the best use of your string trimmer. Ensure that your string trimmer ejects material away from your cut path to avoid working over piles of cut material, which drastically reduces the efficiency of your tool and encourages an uneven lawn trimming.
Tip #4: Use a cutting technique that fits the circumstance of your yard.
You accomplish a well-trimmed lawn by handling your string trimmer with precision. String trimmers seem clunky at best, but you can use a few different techniques to get that even cut you want. Mark Clement from Popular Mechanics suggests these methods:
Tapering: To cut along the boundaries of your lawn, angle the string trimmer so that the line cuts somewhat at an angle. You get your best cut toward the tip of the line, Clement explains, so tilting the trimmer slightly down helps cut smaller, more manageable portions while allowing the line to strike at its strongest point.
Edging: This method is useful when you need to cut grass at the edge of a parallel surface, such as a driveway or sidewalk. Instead of tilting the trimmer down, hold the tool so that the line cuts vertically. Clement notes that edging may uproot rocks and dirt and suggests easing these portions of your lawn into the right cut over time if you haven’t edged before.
Scything: Gently swing your string trimmer in a U-shaped pattern to navigate a difficult or obstructed area of the lawn. This method provides manageable trimming, and by overlapping the pattern, you’ll get the even cut you want.
Screeding: Clement explains that this method of using your string trimmer helps cut grass and weeds growing out of sidewalks, driveways, and other paved areas. Angle your string trimmer so that the line tip is hitting the pavement but the rest is slicing close to the base of the weed or grass.
Tip #5: Take care of your string trimmer.
Not unlike other tools, maintaining your string trimmer will keep it operable for years to come. After every use, wipe off grass and dirt debris from the line or replace it when necessary. String replacement is common, especially if you are using your string trimmer frequently. For gas-powered string trimmers, replace the spark plug every three to four months. Finally, empty the gas tank of the trimmer before long-term storage.
If you buy the right string trimmer for your needs, keep it properly maintained, and remember cutting direction for safety and a good cut, you’ll be using your string trimmer like a pro in no time.

Solve the right triangle ABC (round to the nearest tenth):
angle B =
a =
b =
Answer: angle B= 54 degrees, a=6, b=8
Step-by-step explanation:
Add the two angles we have to get 126 degrees. Subtract that from 180 degrees to get 54 degrees.
We don't know enough to say which is which for a and b, but we can know that it is 6 and 8 because of pythagorean triples (3,4,5).
Answer:
Angle B = 54 degrees, a= 5.88 or round it to 6 and b=8.09 or round it to 8
Step-by-step explanation:
Angle B:
A right angle triangle always equals 180 degrees, and the right angle (the corner) equals 90 degrees.
B = 180 degrees - 90 degrees - 36 degrees
B = 54 degrees
a:
a = 10 sin 36 degrees
a = 5.88 or rounded to 6
b:
b = 10 cos 36 degrees
b = 8.09 or rounded to 8
9. The difference between two numbers is 24. Find the numbers if their
sum is 88.
Answer:
The numbers are 56 and 32
Step-by-step explanation:
Let the two numbers be x and y
x - y = 24
x = 24 + y --- ( 1 )
x + y = 88 --- ( 2 )
Substitute ( 1 ) into ( 2 ):
24 + y + y = 88
2y = 88 - 24
2y = 64
y = 32
Substitute y = 32 into ( 1 ):
x = 24 + 32
x = 56

6.3952 rounded to the nearest tenth
The decimal number 6.3952 rounded to the nearest tenth is 6.40.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, A decimal number 6.3952 and we have to round to the nearest tenth.
To round it to the nearest ten we'll look at the digit at the hundreds place which is 5 so we'll add one to the tens digit and make the digits after that zero.
Therefore, 6.3952 rounded to the nearest is 6.40.

Find a formula for the nth term in this
arithmetic sequence:
a1 = -7, 22 = -1, a3 = 5, 24 = 11, ...
Answer:
[tex]a_n=6n-13[/tex]
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences can be identified because each term is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Here a1 is the first term and r is the common difference.
The given sequence is:
[tex]a_1=-7, a_2=-1,a_3=5,a_4=11,...[/tex]
We can find the common difference by subtracting successive terms:
[tex]a_2-a_1=-1+7=6[/tex]
[tex]a_3-a_2=5+1=6[/tex]
[tex]a_4-a_3=11-5=6[/tex]
Since all the differences are equal, r=6. Thus, the general term is:
[tex]a_n=-7+6(n-1)[/tex]
Operating:
[tex]a_n=-7+6n-6[/tex]
[tex]a_n=6n-13[/tex]
The nth term is:
[tex]\mathbf{a_n=6n-13}[/tex]
