Answers

I thinks A 5/8 hoped this helped

Answer:

C. 5/24

Step-by-step explanation:

John = 3/8

Tim = 1/3

Kevon = ?

---------------------------------

3/8 = 0.375

1/3 = 0.333

0.375 + 0.333 = 0.708

0.292 is left

---------------------------------

5/8 = 0.625 - wrong

9/24 = 0.375 - wrong

5/24 = 0.208333 = 0.293

the inequality x < 1,200. Which number line correctly represents this inequality?

Answers

Answer:

The inequality says X is less than 1200, this means the arrow needs to be pointing to the left. Because X cannot equal 1200, the circle on 1200 should not be filled in. It is only filled in if it is included.

Choose a missing numbers that make the following expression equivalent ____x + 14 and 7 ( 5 x + _____ )​

Answers

Answer:

35x + 14 and 7(5x + 2)​

Step-by-step explanation:

We have to find the missing values that would also make both expressions equivalent.

_x + 14 and 7(5x + _ )​

In the expression, there are some similarities with the placement of the numbers and variables.

Let find the value of the number next to "x".

You can see that we have to use the distributive property to solve the right expression, and once we do so, we can find our first value.

Use the distributive property:

7(5x)

35x

Now we know that our first value is 35x.

To find our second value, we see that in the first equation it is "14", so we need a number that can be multiplied by 7 to make 14.

7 · 2 = 14

Our second number would be 2.

Your final answer would be: 35x + 14 and 7(5x + 2)​

Once you use the distributive property for the second expression, you would get an equivalent expression as the first one.

All the factors of 7 are also factors of 14. True or False?

area of a triangle is 14x^5 + 63x^2. If the base is 7x^2, write an expression to represent the height ( x^2 means x square)

Answers

Answer:

[tex]h=4x^3+18[/tex]

Step-by-step explanation:

Given that,

The area of a triangle, [tex]A=14x^5 + 63x^2[/tex]

Base, [tex]b=7x^2[/tex]

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18[/tex]

So, the height of the triangle is [tex]4x^3+18[/tex].

Clare subscribes to an online music streaming service
for a yearly fee of $96. Starting next month, there will
be a 12% increase in the fee.
The ad for another music streaming service is shown
below. Should Clare switch? Explain.

Answers

Answer:

She should go with service 2 because it is, cheaper. Service 1 cost $107.52, but service 2 cost only $105.

Step-by-step explanation:

Cost now+increase$=new cost

(Part=percent*whole)

Increase=percent increase*cost now

i=12%*$96

i=0.12*96=$11.52

$96+11.52=107.52

Service two⬇️

8.72*12=$105

Yes Clare should switch to service 2 because; cheaper it costs only $105 which is lesser than $107.52

How to Calculate Yearly Fee?

To find the new cost, we will use the expression;

New Cost = Present Cost + increase

However,

Increase = percentage increase * present cost

Increase = 12% * $96

Increase = 0.12 * 96

Increase = $11.52

Thus;

New Cost  = $96 + 11.52

New Cost = $107.52

For Service two;

We are told that digital streaming costs $8.75 per month. Thus;

Cost = 8.75 * 12

Cost = $105

Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

6x + 12 = 8x - 8

Subtract 6x from both sides.

12 = 2x - 8

Add 8 to both sides.

20 = 2x

Divide both sides by 2.

x = 10

The value of 10 for x will make the given parallelogram a rhombus.
