Answer:

They can paint 1050 sq.feet with 3 gallons of paint

Step-by-step explanation:

Given :Stacy and Neil painted 280 ft2 of there living room wall with 4/5 gallon of paint.

To Find : How many square feet can they paint with 3 gallons of paint?

Solution :

Area painted with [tex]\frac{4}{5}[/tex] gallons of paint = 280

Area painted with 1 gallon of paint =[tex]\frac{280}{\frac{4}{5}} = 350 ft^2[/tex]

Area painted with 3 gallons of paint =[tex]350 \times 3 = 1050 ft^2[/tex]

Hence they can paint 1050 sq.feet with 3 gallons of paint

The two consecutive even integers are 8 and 10.

Given that, three times the smaller of two consecutive even integers is four less than twice the larger.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let two consecutive even integers be x and x+2.

Now, 3x-4=2(x+2)

⇒ 3x-4=2x+4

⇒ 3x-2x=4+4

⇒ x=8

So, x+2=10

Therefore, the two consecutive even integers are 8 and 10.

Answer:

dont come at me if im wrong but im pretty sure the answer is 1/2 or .5

Step-by-step explanation:

The percentage of fruit is there in the cake will be 11%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Mass of cake = 2.5 kg

And, The amount of fruit = 275 g

Now,

Find the percentage of fruit is there in the cake as;

Since, Mass of cake = 2.5 kg

                               = 2,500 g

And, The amount of fruit = 275 g

So, The percentage of fruit = 275 / 2,500  x 100

                                          = 0.11 x 100

                                          = 11%

Thus, The percentage of fruit is there in the cake will be 11%.

The two points on the line y = − 56x − 4 will be (1, −60) and (−1, 52).

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

y = − 56x − 4

Let x = 1, the value of y will be

y = − 56 (1) − 4

y = − 56 − 4

y = − 60

Let x = − 1, the value of y will be

y = − 56(−1) − 4

y = 56 − 4

y = 52

The two points on the line y = − 56x − 4 will be (1, −60) and (−1, 52). Then the diagram of the line is given below.

Answer: The share would be approximately $285, $175, $141 respectively.

Step-by-step explanation:

Since we have given that

Number of box tops collected by Mr. Aceves's class = 3760

Number of box tops collected by Mrs. Baca's class = 2301

Number of box tops collected by Mr, Canyon's class = 1855

We first find the ration of box tops of Mr. Aceves, Mrs. Baca and Mr. Canyon respectively:

3760:2301:1855

Total = 3760+2301+1855=7916

Total amount to be share among them as a prize = $600

Mr. Aceves's share is given by

[tex]\dfrac{3760}{7916}\times 600\\\\=284.99\\\\\approx 285[/tex]

Mrs. Baca's share is given by

[tex]\dfrac{2301}{7916}\times 600\\\\=175.08\\\\\approx 175[/tex]

Mr. Canyon's share is given by

[tex]\dfrac{1855}{7916}\times 600\\\\=140.60\\\\\approx 141[/tex]

Hence, the share would be approximately $285, $175, $141 respectively.

The distributive property of multiplication is used to simplify 7 x 22. By substituting 22 with 20 + 2 and distributing the multiplication, it becomes 7 x 20 plus 7 x 2, which equals 154.

The question is asking us to use the distributive property of multiplication to calculate 7 x 22. The distributive property allows us to multiply a single term and two or more terms inside a set of parenthesis. Here we are given the hint that 22 = 20 + 2.

Following the hint, we substitute 22 with (20 + 2) in the multiplication expression. So, 7 x 22 becomes 7 x (20 + 2). Now, by distributive property, we can take the multiplication inside the parenthesis.

By adding both these results, 140 + 14, we get the final answer 154.

Answer:

the correct APEX answer is $4999.17

The cost of car is $4,999.16.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A used-car dealer has a vehicle on the lot with a sticker price of $5999.

Mark up = 20%

let the cost of Car be x.

So, x+ 20% of x = 5999

x + 20/100 x = 5999

x + 0.20 x = 5999

1.2 x= 5999

x = 5999/ 1.2

x = $4,999.16

Hence, the cost of car is $4,999.16.

Answer:

4/5

Step-by-step explanation:

The purple paint is split into 16+3+1=20 parts: 16 parts of white, 3 parts of blue, and 1 part of red. Thus, in one gallon of purple paint, 16 out of the total 20 parts are white paint, so there are 16/20 x 1 gallon = 4/5 gallons of white paint in one gallon of purple paint.

The amount of white paint that is needed in order to make a gallon of purple paint would be 4 / 5 gallons.

The ratio of white:blue:red paint is given as 16:3:1. The sum of these ratio components gives the total parts for one 'unit' of paint.

So, 16 (for white) + 3 (for blue) + 1 (for red) = 20 total parts.

This implies that the 20 parts in this ratio make up 1 gallon of purple paint (as per the question). To find the quantity of white paint needed, we simply need to convert the 'parts' of white paint into gallons.

Since 20 parts is equivalent to 1 gallon, 1 part would be equivalent to 1/20 of a gallon. Therefore, 16 parts of white paint would be equivalent to :

= 16 * (1/20)

= 16/20

= 4/5 gallons

Answer:

400+ (15c)

$670

Step-by-step explanation:

Eliza earns per week = $400

She earns for each new customer's signs up = $15

Let the number of new customers Eliza signs up = c

The expression that shows her earning in a week will be

400+ (15c)

If the number of customers that signs up = 18

The weekly earning of Eliza will be = 400+(15 × 18)

                                                          = 400 + 270

                                                          = $670

Eliza's earning in a week would be $670.

The inequality will be;

⇒ 9 ≥ 15 - x

Where, x  is a number.
