Answer 1

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

We can use the rise over run method to do this question.

Let's start at the coordinates (1,1)

If we go down 2 from that point and to the right 3 times then we see another point on the line (3, -1).

We would express this as 2 over 3 or [tex]\frac{2}{3}[/tex].

We aren't done yet however.

The line is sloping downwards and this means that the slope is negative.

So, the final answer is [tex]-\frac{2}{3}[/tex]

I hope this helps!!

On the coordinate plane shown, Figure 1 is transformed into Figure 2, which is transformed into Figure3. Figure 1 and Figure 3 are similar by a sequence of transformations. What type of transformation was used to transform Figure 1 into Figure 2?

Answers

Answer:

rotation

Step-by-step explanation:

The transformation used to transform figure 1 into figure 2 is a dilation.

What is dilation?

A dilation is a transformation that yields a picture that differs in size while maintaining the original image's shape.

Given that, figure 1 is transformed into figure 2, and figure 2 is transformed into figure 3 which s similar to figure 1.

Since figure 1 is similar to figure 3, as per the transitivity property, figure 1 is similar to figure 2.

Since figure 1 is similar to figure 2, the ratio of their side lengths is proportional.

Since the ratio of the side lengths of the two figures is proportional, the transformation is a dilation.

Hence, the transformation used to transform figure 1 into figure 2 is a dilation.

On a hike, each hiker carries the items shown (down below says what items and its weight). Write and interpret an expression in simplest form that represents that weight (in pounds) carried by x hikers,

3.4 lb sleeping bag,
4.6 lb backpack,
2.2 lb water bottle.

Expression: _____
The weight carried by each hiker is ______ pounds.

Answers

Answer:

The wording of this question is vague.  Are the numbers 3.4, 2.2, and 4.6 the weights in pounds (lbs) of the individual items carried by each hiker?  I will assume that each of x hikers carries 3 items of weights 3.4, 2.2, and 4.6 lbs, and I will assume that you seek the total weight W carried by the group of x hikers.

W = (number of hikers)(pounds carried by each hiker) = x(3.4 + 2.2 + 4.6) lbs.

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence.

Answers

Answer:

in about 0.92 hours or 55.2 minutes

Step-by-step explanation:

The time they take to paint the room:

Pragnesh and Qazi  = 2 hours

Pragnesh and Ronghui = 3 hours

Qazi and Ronghui = 4 hours

Meaning, each hour (1)  they'll paint:

Pragnesh and Qazi  =  [tex]\frac{1}{2th}[/tex] of the room

Pragnesh and Ronghui = [tex]\frac{1}{3th}[/tex] of the room

Qazi and Ronghui = [tex]\frac{1}{4th}[/tex] of the room

By summing all their work abilities we can determine how long it would take if all three students worked together to paint the fence, which is:

[tex]\frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{13}{12th}[/tex] of the room each hour. Therefore the whole (1) room would be painted in 1 ÷ [tex]\frac{13}{12}[/tex] = [tex]\frac{12}{13} hours[/tex] or 0.92 hours or 55.2 minutes (0.92 * 60).

Step-by-step explanation:

Remember PEMDAS. This will help you a lot in algebra.

P Parenthesis

E Exponents

M Multiplication

D Division

A Addition

S Subtraction

This is the order of how all the operations should take place.

Note: Multiplication and Division happen together. Just go from left to right. This is the same for Addition and Subtraction.

Onto the problem!

First, look at PEMDAS.

P stands for Parenthesis so first we look for those.

In this case, we have a set here. Solve whatever is inside.

[tex]\frac{1}{2}*(4+8)[/tex]

[tex]\frac{1}{2}*(12)[/tex]

Next, look for Exponents. There aren't any in this expression, so we're okay to move on.

Now, look for Multiplication or Division.

[tex]\frac{1}{2}*(12)[/tex]

[tex]6[/tex]

The answer is 6.

1. 1/2 (AB) = AM
2. 1/2 (AB) = MB
3. AM = MB
4. CD = AB

Answers

Answer:

I believe the answer is 3. AM = MB

Step-by-step explanation:

For the first option, 1/2 of AB is obviously equal to AM. Therefore, the second option is also correct.

As far as the fourth option, CD equals AB since a compass was used to gather the points, ensuring they are equidistance.

Juan plans to build a bookcase to store his paperback books, DVDs, and CDs. He has lumber that he will use for the sides and the back of the bookcase. The bookcase will have five shelves, and each will be 2 1/2 long.Does he have enough lumber to make the five shelves?

Answers

Answer:

Juan does not have enough lumber to make the five shelves.

Step-by-step explanation:

Let assume that:

If Juan bought a piece of lumber that is 18 feet long.

and the bookcase will have = 5 shelves

Also, the length of each bookcase = 2 1/2 long = 2.5 long

Then the amount required for the five shelves = 5 × 2.5

= 12.5 feet long

Therefore, we can say Juan does not have enough lumber to make the five shelves.

Hence, he will need an addition of: (18 - 12.5) feet = 5.5 feet piece of lumber

-24 - 9 = 3x

-33 = 3x

-33/3 = x

-11 = x

x = -11

Add 9 to both sides

So

-15=2x

Divide both sides by 2

So

X=-7.5

A rectangle's one side is 7 inches shorter than four times it's other side. The perimeter is 180 inches. What are the sides? Please explain with steps and if your can tell me why I keep getting 19.4.

Answers

Answer:

Step-by-step explanation:

we call one side x and the other side 4x-7. Because in a rectangle opposite sides are equal we can now set up an equation.

x + x + 4x-7 +4x-7 = 180

              10x - 14 = 180

                   10x = 194

                    x = 19.4

the lenght of the other side is 4(19.4)-7 = 70.6

Step-by-step explanation:

In an equation, the additive property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.

transitive property,  If a = b and b = c, then a = c.

Segment Addition Postulate Defined. The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.
