Solve the equation for d.

Answers

Answer 1

Answer:

[tex]d=\frac{f+4}{3}[/tex]

Step-by-step explanation:

3d - 4 = f

add 4 to both sides

3d = f + 4

divide both sides by 3

d = f/3 + 4/3

I need help with B.

Answers

Answer:

6x= 42

x= 7

Step-by-step explanation:

a) Area= length ×width

2100= 50 ×width

width= 2100 ÷50

width= 42 ft

Thus, the field is 42ft wide.

b) width of field

= x +3x +2x

= 6x

Since we know that the field is 42ft wide from (a),

Equation: 6x= 42

x= 42 ÷6

x= 7

A field in the shape of a square has an area of 8,100 square feet. How can you determine the length of one side of the field?

Answers

To determine the length of one side use the formula for the area of square. As a square is equal on all four sides, finding one length results in any of the four. Solve using the formula and you receive your answer of 90.

A = s²

8100 ft² = s² (set up formula)

√8100 ft² = s² ( get s alone by squaring both sides)

90 ft = s (answer)

We can conclude that the side of the given square with an area of 8100ft² is 90ft.

What is a square?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length. A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90-degree angles.

So, the area of the square is 8100ft².

Formula: s²So, we know that: 8100 = s²

Now, calculate for s as follows:

s² = 8100s = √8100s = 90ft

Therefore, we can conclude that the side of the given square with an area of 8100ft² is 90ft.

work it out "the equation 1.5r + 15=2.25r represents the number r of movies u must rent to spend the same amount at each movie store. how many movies must u rent to spend the same amount at each movie store" then there's 2 pics one says "all rentals $1.50, membership fee $15" other says "membership free, all rentals $2.25"

Answers

Answer:

Step-by-step explanation:

Your equation is correct. To solve it subtract 1.5r from both sides and divide by the resulting coefficient of r.

15 = 0.75r

15/0.75 = r = 20

You must rent 20 movies for the costs to be the same.

Jackson was selling cups of lemonade. On Saturday, he sold a total of 14 cups. On Sunday he sold cups at a steady rate of 3 cups per hour. Set up and solve an equation to find how many hours, h, it took Jackson to sell 47 cups (including those from Saturday).

Answers

Answer:

(47-14) h ÷ 3 =11

Step-by-step explanation:

47-14=33

33 divided by 3 is 11

Jackson takes 11 hours to sell 47 cups.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the number of hours that Jackson sold his cups on Sunday.

Now,

Saturday cups + Sunday cups = Total cups.

14 + 3x = 47

3x = 33

x = 11

Hence "Jackson takes 11 hours to sell 47 cups".

Answer: A

Step-by-step explanation:

f(x)=ax²+bx+c is the standard form for quadratic functions. Looking at the answer choices, we can eliminate B, C, D. They are not the same as the given standard form. B and C are point-slope formulas, which are not standard form. D is in intercept form, therefore it is not standard form. This leaves us with A as the correct answer.
