Hello again davetriona12! I can help you.

We have 2.99, 3.19, 3.39, and 3.79

In order to solve this, we need to find out how much is being added every time. To do this, we will subtract 2.99 from 3.19 which gives us 0.20

So each time, 0.20 gets added.

Now that we have that information, we are ready to find the blanks.

For the first blank, we will subtract 2.99 - 0.20 which will give you 2.79

For the second blank, we will add 0.20 to 3.39 which will give you 3.59

Hope this helps you!

Which statement describes the relationships between x and y in these two equations?

y = 3x

y = x + 3

In y = 3x, the value of y is 3 times the value of x, and in y = x + 3, the value of y is 3 more than the value of x.

In y = 3x, the value of y is 3 more than the value of x, and in y = x + 3, the value of y is 3 times the value of x.

In y = 3x and y = x + 3, the value of y is 3 more than the value of x.

In y = 3x and y = x + 3, the value of y is 3 times more than the value of x.

A _____________ ratio in any proportional relationship.

Answers

Answer:

a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x

If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

Step-by-step explanation:

Proportions are the same ratios written in different forms. A proportional relationship is states that they are the same. For example, 1/2 and 6/12 have a proportional relationship, which means they are the same.

Mr. Jackson has a total of 12 employees. He wants to buy each employee 3 aprons that will cost $7.79 each, 1 cap that will cost $5.68, and a t-shirt that costs $13.99. How much will Mr. Jackson need to spend to purchase the items for his employees?

Answers

12/3 is 4 so multiply each by 4 so 7.79 x 4 is 31.16 5.68x4 22.72 13.99x4 55.96

31.16 + 22.72+ 55.96

Answer: $109.84

Answer: $516.48

Step-by-step explanation: Multiply 7.79 by 3 because it's 3 for each employee then multiply by 12 for each employee which equals 280.44. then 5.68 x 12 which is 68.16 for the cap. then 13.99 x 12 for the shirt which is 167.88. add 280.44, 68.16, and 167.88 to get 516.48.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an expression.

We have,

From the table,

The pattern that describes the table.

Let the pattern be z = mw + c

Now,

(3, 27) and (5, 45)

m = (45 - 27) / (5 - 3) = 18/2 = 9

Now,

(3, 27) = (w, z)

27 = 9 x 3 + c

27 - 27 = c

c = 0

Now,

The pattern for the table.

z = 9w

Thus,

The patter for the table is z = 9w.

What is the prime factorization of 88?
A.8✖11
B.2✖4✖11
C.4✖4✖11
D.2✖2✖2✖11

Answers

The answer is d
Hope this helps :)

Answer:

D. 2✖2✖2✖11

Step-by-step explanation:

To get the Prime Factors of 88, you divide 88 by the smallest prime number possible. Then you take the result from that and divide that by the smallest prime number. Repeat this process until you end up with 1.

88 ÷ 2 = 44

44 ÷ 2 = 22

22 ÷ 2 = 11

11 ÷ 11 = 1

Again, all the prime numbers you used to divide above are the Prime Factors of 88.

It means how many floors are to be allocated in a certain area of space.

Step-by-step explanation:

Answer:

Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet

A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached.
Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.
write three expressions

Answers

Answer:

-12

Step-by-step explanation:

The three equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

From the question,

Each float takes a step of 5 unitsEach group takes a step of 2 units

So, the final position of the submarine is:

Final = -(5)(3) - (2)(4)

The minus "-" sign implies that the submarine moves downwards i.e. it sinks

The equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)
