Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?

Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)

Answers

The correct answer is Point A' is located at (-5, -4).

When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Point A’ is located at (-5,-4)

The model shows the expression 20 + 16.

A model with 4 rows of 5 squares and 4 rows of 4 squares.

Which expression is equivalent to this sum?
4 (5) + 4
4 + 5 + 4
4 (5 + 4)
5 (4 + 4)

Answers

Answer:

4(5+4)

Step-by-step explanation:

20 + 16 = 36

Think of PEMDAS (In this scenario you have parenthesis and addition)

4(5+4) = 20 + 16

4 (9)    =    36

36       =    36

While looking at the other options:

4 (5) + 4 = 24

4 + 5 + 4=13

5 (4 + 4)= 40

Answer:

4 (5 + 4)

Step-by-step explanation:

1. the model show 20 + 16 which = 36

2. the first example 4 (5) + 4  which equals 20 + 4 or 24.

3. the second example 4 + 5 + 4  which equals 9 + 4 or 13.

4. the third example 4 (5 + 4) , using order of operations, equals 4 x 9 and that equals 36.

5. the last examples 5 (4 + 4)  is 5 x 8 which is 40.

That is why the third example is correct!

Answer: conversion factor is just how much of it is in another unit

Step-by-step explanation:

for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.


Original rate (15 miles) x conversion factor (5280 feet are in a mile)

So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

The answer is 3 but the conversion factor is 3ft 1 yard

help asap if answer is correct and provided explanation i will give brainiest.

Answers

Answer:  0.40

Reason:

6 black out of 4+6+5 = 15 total

6/15 = 0.40 is the experimental probability of selecting black.

Side note: The term "empirical probability" is the same as "experimental probability".

The experimental probability of selecting a black marble will be 0.40. The correct option is C.

What is probability?

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.

Probability = Number of favourable outcomes / Number of samples

Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.

Number of favourable outcomes = 6

Number of samples = 4+6+5 = 15

Probability = Number of favourable outcomes / Number of samples

Probability = 6 / 15

Probability = 0.40

Therefore, the probability will be 0.40.

You start off with $34 so +34

Then you spend $76 so -76

Then you deposit $30 so +30

There are several ways to go about this but i find the easiest way is to add the positives first.

We're going to say 34+30=64

Next we subtract 76 from 64= -12

You go about this in the same way you would if it didn't have a negative sign in front of it. Then since the 76 is the larger number you add the negative sign.

4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?

Answers

To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.

Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.

The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.

The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.

The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:

0.32 + 0.02x = (4/100) * (4 + x)

Simplifying the equation:

0.32 + 0.02x = 0.04(4 + x)

0.32 + 0.02x = 0.16 + 0.04x

0.02x - 0.04x = 0.16 - 0.32

-0.02x = -0.16

Dividing both sides by -0.02:

x = (-0.16) / (-0.02)

x = 8

Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

To solve this problem, we can use the following equation:

4+x4×8+x×2​=4

This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.

To find x, we can simplify and solve for x:

4+x32+2x​=4

32+2x=16+4x

16=2x

x=8

Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

1. A straight fence is constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. A certain fence begins and ends with a post. If there are 7 posts, what is the total length of the fence?​

Answers

Answer:

72

Step-by-step explanation:

First, we will multiply the number of posts (7) by the posts' width (6) to get 42.

Since there is a chain between each post, there are 6 chains.

Multiplying the number of chains (6) by the chains' length (5), we get 30.

The question asks us to find the total length of the fence, so we add 42 and 30 and get 72.

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

I think i can help! First, the rental fee is basically what you have to pay to get access to the item. It means that no matter how many hours you rent the item for, THE RENTAL FEE ALWAYS STAYS THE SAME. Next, The cost per hour is what you have to pay for every item you use the item. To figure out the cost per hour, all you need to do is multiply the cost per hour by the number of hours you are using the item. Lastly, the total cost if you are only using the item for one hour is the sum of the cost per hour and the rental fee. If you are using an item for more than an hour, like i said before, the rental fee always stays the same and you need to multiply the cost per hour by the number of hours you used the item. that’s all i can say my brains hurts now lol

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)
