Answer:

4/12

Step-by-step explanation:

if you look 6/12 wasn't simplified so I would guess that you would leave it as 4/12

Answer:

218

Step-by-step explanation:

this is ratio.

5+4=9. which is the ratio you add it.

5/9×360=200

therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.

therefore the number of boys in school from january to february is 218.

The decimal number 6.3952 rounded to the nearest tenth is 6.40.

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.

Answer:

y = 1/2x - 1

Step-by-step explanation:

This formula is currently written in point-slope form (y+ + y1 = m (x + x1). To graph it easier, the first thing you would do is make it slope-intercept form (y=mx + b).

First, distribute the 1/2 into the parenthesis.

1/2(x+2)

1/2x + 1

Then, the equation should look like this: y+2 = 1/2x + 1

The next step is to subtract the 2 from both sides.

It should look like this:

y = 1/2x -1

Graph it by first plotting the y-intercept, -1, on the y-axis, and counting up 1 space and to the right 2 spaces, then drawing a line. I hope this helped!

Answer:

I will give you the best knowledge I can offer at this moment.

One thing to understand:

- When dealing with angles in a triangle, know that EVERY angle has to add up to 180*. ( * = degrees)

Based on the image provided, I'm assuming that you are learning how to classify triangles based on the angles and side lengths. There are mainly 6 types of triangles:

3 based on sides

3 based on angles

The 3 based on sides

Scalene Triangle

A scalene triangle has all side lengths of different measures. No side will be equal in length to any of the other sides in such a triangle. In a scalene triangle, all the interior angles are also different.

Isosceles Triangle

In an isosceles triangle, the lengths of two of the three sides are equal. So, the angles opposite the equal sides are equal to each other. In other words, an isosceles triangle has two equal sides and two equal angles.

Equilateral Triangle

In an equilateral triangle, all the lengths of the sides are equal. In such a case, each of the interior angles will have a measure of 60 degrees. Since the angles of an equilateral triangle are same, it is also known as an equiangular triangle.

The 3 based on angles

Acute Triangle

An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.

Obtuse Triangle

Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.

Right Triangle

A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse. You may come across triangle types with combined names like right isosceles triangle and such, but this only implies that the triangle has two equal sides with one of the interior angles being 90 degrees.

I hope this information helps with your math class and studies!

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.

Answer:

Yes, SAS theorem. Angle ACB and Angle ECD are congruent because of the vertical angles theorem.

Step-by-step explanation:

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
