HELP PLESSE ITS MULTIPLE CHOICE

HELP PLESSE ITS MULTIPLE CHOICE

Answers

Answer:

Letter A

Step-by-step explanation:

First of all, we have to solve all the equations

First one is (4*1)-6

We have to use PEMDAS

which stands for

Parenthesis

Exponents

Multiplication

Divison

Addition

Subtraction

In (4*1)-6  

You have to do 4*1 first ~ which equals 4

the next step would be 4-6  ~  which equals -2

The next equation would be (1*4)-6

First do 1*4  ~ which is 4

Next 4-6  ~ which again equals -2

Next equation is (1*6)-(4-6)

Parenthesis first, 1*6=6

4-6=-2

6-(-2)

which equals 8

Our next equation is 6-(1*4)

1*4=4

6-4~ which equals 2

Our last equation is 4*(1-6)

Parenthesis comes first, so it would be 1-6 first

which equals -5

4*(-5) would be our final step  ~  which equals -20

All of our answers would be

-2 - from the top equation

-2 - from letter A

8 - from letter B

2 - from letter C

-20 - from letter D

which means Letter A is the answer.

Hope this is helpful.

Elsa and Anna are running a race. Elsa is running at a rate of 2 meters per second and Anna is running at a rate of 1.75 meters per second. If Anna is given a 10 meter head start, how many seconds would it take for Elsa to catch up? Use an equation or system of equations to solve.

Answers

Step-by-step explanation:

Since Elsa is running at 2 and Anna at 1.75, we can first subtract

2 - 1.75 = 0.25, meaning each second Else gains 0.25m

Now that Anna was given a 10m headstart, we can divide 10 by 0.25

10/0.25 = 40

Meaning it would take 40 seconds for Elsa to catch up

the answer is 40, enjoy lol

Answers

Answer:

x= uk/k+y

Step-by-step explanation:

Combine the expression and isolate the variable x

multiply both sides by kx
kux = x+y

add -x to both sides
kux+ (-x) =x+y+ (-x)

kux-x=y

factor out variable x
x(ku-1)=y

divide both sides by ku-1
x(ku-1) y

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Write three decimals that are equivalent to 6x1 + 4x1/10​

Write three decimals that are equivalent to 6x1 + 4x1/10

Answers

Answer: 6.4 and any other decimals that are a multiple of 6.4


Explanation: 6x1 + 4x1/10=6+0.4=6.4

The decimal is 6.4 which is equivalent to 6×1 + 4×1/10.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that the expression as:

⇒  6×1 + 4×1/10

Apply the arithmetic operations in the terms,

⇒ 6 + 4×0.1

⇒ 6 + 0.4

⇒ 6.4

Thus, the decimal is 6.4 which is equivalent to 6×1 + 4×1/10.

Answer:

282 cubic inches

Step-by-step explanation:

Let's have A be the top figure, B the middle, and C the bottom.

First, we need the volume for A, B, and C. And after, add them up.

Figure A : 1 · 5 · 2 = 10 cubic inches

Figure B : 3 · 3 · 8 = 72 cubic inches

Figure C : 10 · 4 · 5 = 200 cubic inches

Now we add A+B+C, so the equation is:

                10+72+200=282 cubic inches

Hence, the volume of the this figure is 282 cubic inches.

the volume of the figure is 282 cubic inches

The height of the dead tree is 16 feet

The direction in which the tree should fall is Northeast, Northwest, Southeast, Southwest.

How to solve

From the given question, since the ray is straight, AC is parallel to DF

Meanwhile triangles ABC and DEF are right angles,

AB/DE =BC/EF

AB/6 = 8/3

AB= 16 feet.

Thus, the height of the tree is 16 feet.

Since 16 ft> 15ft> 14ft> 13ft> 12ft

Therefore, the direction which the tree is falling is Northeast, Northwest, Southeast, Southwest.

The answer is 130/100.

Answer:

130/100 or 1 30/100

explanation:

There are 130 squares in all that is colord in. And there are 100 squares in each diagrahm.

So the fraction of that is 130/100.

Also, 1 whole diagrahm is colord in. So that would be represented as 1, and on the other diagrahm, there are 30 squares that are colored in out of 100.

So that is 1 30/100
