The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.• The art club raised about $3,200 and charged $6 per car.• The music club earned approximately $3,800, charging $8 for each car.• The drama club took in nearly $2,900, at a cost per car of $7. About how many cars did each of the clubs wash?

Answer:

[tex]y=-\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Slope-intercept form means

[tex]y=mx+c[/tex]

where m is given its the slope which is [tex]-\frac{3}{2}[/tex] and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

[tex]y=mx+c[/tex]

[tex]-5 = -\frac{3}{2}(4)+c[/tex]

[tex]-5=-6+c[/tex]

[tex]c=1[/tex]

now we know the value of slope which is given [tex]-\frac{3}{2}[/tex] and we found the value of which is 1 so we put these values into our original slope-intercept form equation

[tex]y=mx+c\\\\y=-\frac{3}{2}x+1[/tex]

Answer:

((2 x^2 + 1)^2)/(x^2)

Step-by-step explanation:

Simplify the following:

(2 x + 1/x)^2

Hint: | Put the fractions in 2 x + 1/x over a common denominator.

Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:

((2 x^2)/x + 1/x)^2

Hint: | Combine (2 x^2)/x + 1/x into a single fraction.

(2 x^2)/x + 1/x = (2 x^2 + 1)/x:

((2 x^2 + 1)/x)^2

Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.

Multiply each exponent in (2 x^2 + 1)/x by 2:

Answer: ((2 x^2 + 1)^2)/(x^2)

Answer:

King size(x): 3

Regular size(y): 2

Steps:

System of Equations:

x+y = 5

3.75x+1.75y = 14.75

Multiply 3.75 on all sides.

3.75x+3.75y = 18.75

3.75x+1.75y = 14.75

Subtract top and bottom

            2y  = 4

            /2      /2

             y   =  2

After you know regular size amount, figure out king size ----3.

5-2 = 3.    

Answer:

Step-by-step explanation:

m∠B = 90°

m∠C = 90° - 27° = 63°

cos27° = [tex]\frac{200}{b}[/tex] ⇒ b ≈ 224.5

sin27° = [tex]\frac{a}{b}[/tex] ⇒ a ≈ 101.9

y = -3/2x + 5/2

Explanation-

slope intercept form is y = mx + b

so we have to solve the equation for y

2y = 5 - 3x

y = 5/2 -3/2x

or

y = -3/2x + 5/2

Answer:

slope = - [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (2, 11)

m = [tex]\frac{11-3}{2-9}[/tex] = [tex]\frac{8}{-7}[/tex] = - [tex]\frac{8}{7}[/tex]

Answer:

[tex]\boxed {m = -\frac{8}{7}}[/tex]

Step-by-step explanation:

Use the Slope Formula to help you determine the slope of two given points:

[tex]m =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

First point: [tex](x_{1}, y_{1})[/tex]

Second point: [tex](x_{2}, y_{2})[/tex]

-Apply the two given points onto the formula:

First point: [tex](9, 3)[/tex]

Second point: [tex](2, 11)[/tex]

[tex]m =\frac{11 - 3}{2 - 9}[/tex]

-Solve for the slope:

[tex]m =\frac{11 - 3}{2 - 9}[/tex]

[tex]m =\frac{8}{-7}[/tex]

[tex]\boxed {m = -\frac{8}{7}}[/tex]

Therefore, the slope is [tex]-\frac{8}{7}[/tex].

Answer:

2/3

Step-by-step explanation

The length of the park has been cut off in the question but if it is one mile, like I think it is, then this is the answer.

A = 2/3

A = L x W

2/3 = 1 X ?

? = 2/3

Answer:

width = 2/3 mile

Step-by-step explanation:

area = L * W

where area = 2/3 mile²

       length  = 1 mile

         width = ?

2/3 = 1 (W)

2 = 3W

W = 2/3 mile

therefore the width = 2/3 mile

                     length = 1 mile

Answer:

m<QRS=48°

m<RSQ=69°

m<RQS=63°

Step-by-step explanation:

Since we know that the measures of the angles of any triangle is 180°, we can form this equation: 7a-1+10a-1+9a=180°

Then, we can use simple algebra to solve for a and plug in that value into the equations that the degrees represent to get our angle measures.

7a-1+10a-1+9a=180°

26a-2=180°

26a=182°

a=7

Now, plug in that value of a and you have your anlage measures!! Hope this helps!! :)

Answer:

Common factors between the two numbers is 3 and 1.

Step-by-step explanation:

The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1.

The factors of 45 are 45, 15, 9, 5, 3, 1.

The value of the prime number which is a factor of 42 and 45 would be  3.

Used a concept of prime number that states,

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. Numbers that have more than two factors are called composite numbers.

Given that the two numbers are 42 and 45

Now, factors of numbers 42 and 45 are,

The Factor of 42 are

1, 2, 3, 6, 7, 14, 21, 42

And, The factors of 45 are

1, 3, 5, 9, 15, 45

So, the prime number that is a factor of 42 and 45 is 3.

I think its 80 not sure

Step-by-step explanation:

The measure of ∠A will be 50°.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Δ ABC ≅ Δ DEF

And, m ∠A = (x + 30)°, m ∠C = 45°, and m ∠D = 80°

Now,

Since, Δ ABC ≅ Δ DEF

Hence,  m ∠A = m ∠D

Substitute all the values, we get;

m ∠A = m ∠D

x + 30 = 80

Subtract 30 both side, we get;

x = 80 - 30

x = 50°

Thus, The measure of ∠A will be 50°.
