Cost of a ticket = Total cost ÷ number of tickets

                         = 20 ÷ 5

                         = $ 4

2) Cost of 7 books  = $ 22

Cost of a book = 22 ÷ 7

                         = $ 3.11

Answer:

A.43.0

Step-by-step explanation:

area of rectangle= l*w=10 units *20 units= 200 units^2

area of the 2 circles:

diameter= 20/2=10 units

r=d/2= 10/2=5 units

area of a circle= 3.14*r^2

=3.14*5*5

=78.5> the 2 circles are identical then they have the same area

area of the shaded region= area of the rectangle- 2*area of one circle

= 200- (2*78.5)

=200-157

=43.0

therefore the area of the shaded region is 43.0 units^2

Answer:

Slope (m) = 5

Y-intercept (b) = 3

Step-by-step explanation:

The equation of a line is y = mx + b, where (m) is the slope and(b) is the y-int.

Knowing this, we see that the slope is 5 and the y-int is 3.

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 10 does indeed equal 10.

∴ x = 5/4 is the solution to the equation.

Answer:

y=4x+5(the first one)

y=4x+1

y=4x-4

Step-by-step explanation:

If the slope is the same, it is parallel

The equation for a linear equation is y=mx+b

mx is the slope

your original equation is y=4x-2, so the slope is 4.

To find which ones are parallel, you find the ones with the slope 4x(make sure it isn't -4x).

x - 7 = 0

x = 7

Answer:

x=−3 or x=7

Step-by-step explanation:

(5x+15)(x-7)=0

Answer:

do the following

Step-by-step explanation:

the question says that the line is passing thur the point 1,1 ... so when x = 1 so does y ... also  when  x= a.. then y=0 and when y=b then x =0  .. and this is a straight line... also  1/a + 1/b = 1

if you were to draw on a graph... this .. you would see that when b=2  then x=0 and also when a=2.. then y = 0  ....

and 1/2 + 1/2 =1

so that's the line.... draw in just roughly.... you'll see... then what is the equation of that line.. usually we would use  the slope intercept formula for the equations.. there are more than one way to show the line.. is my point.. but.. if we use  y = mx + b  where m = -1   and b = 2 then...

y= - x+2

That answer got long.. sorry :/

Answer:

step by step

Step-by-step explanation:

Line passing (a,0) (0,b)

slope = (y2 - y1) / (x2 - x1) = - b/a

pass (0,b), y interception: b

Line: y = -b/a * x + b  

pass(1,1) y=1, x=1

1 = -b/a + b  

1/b = (-b/a) /b + b/b

1/b = -1/a + 1

1/a + 1/b = 1  

Answer:

Four-fifths (4/5)

hope it helps!

Answer:

Four-fifths

Step-by-step explanation:

To convert this decimal into a fraction remove the decimal and divide by 10, so the new fraction looks like 8/10. You do this because the eight is in the tenths place, so it literally translates to eight-tenths. However, fractions need to be in the simplest form so you divide both the numerator and denominator by 2 to get the final answer 4/5 or four-fifths.

Answer:

b

Step-by-step explanation:

It will take [tex]\frac{20}{9}[/tex] hours as per linear equation to complete the wall.

A linear equation is an equation where the variable of the equation has the highest power of degree one.

Given, the 1st bricklayer build a complete wall of certain size in 5 hours.

Therefore, that bricklayer build [tex]\frac{1}{5}[/tex]th of the complete wall in 1 hour.

Similarly, the 2nd bricklayer build a complete wall of certain size in 4 hours.

Therefore, that bricklayer build [tex]\frac{1}{4}[/tex]th of the complete wall in 1 hour.

If they work together, in 1 hour they build a total of ([tex]\frac{1}{5}[/tex]+[tex]\frac{1}{4}[/tex])th = [tex]\frac{9}{20}[/tex] of the complete wall.

Hence, they will complete the wall in (1÷[tex]\frac{9}{20}[/tex]) hours = [tex]\frac{20}{9}[/tex] hours.

Answer:

1.3 inches

Step-by-step explanation:

1. Determine what you already know in order to set up the equation:

1 inch = 100 miles

x inches = 130 miles

Solving for x

2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)

[tex]\frac{100}{1}[/tex] = [tex]\frac{130}{x}[/tex]

3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)

100x = 130

4. Divide each side by 100 to isolate the variable.

x = 1.3

Answer: No

Currently we don't have enough information to prove this quadrilateral is a parallelogram. One piece of information that would be useful would be if the other diagonal is bisected. If that's the case, then we have a parallelogram (we would first prove the triangles congruent and then use the corresponding congruent angles to set up the parallel lines). Unfortunately, we only know about one diagonal being bisected, but not both, so we don't have enough info.

Answer:

Part A - The answer is C

Part B - a.true, b.true, c.false, d.true.

Step-by-step explanation:

Part A

The slope shown on the table is -60 because the table shows that after each hour, the Gallons of Water decrease by 60.

Part B

a. The slope is -60 not -600, this was established on Part A.

b. We start off with 600 gallons of water. The equation is y = 600 - 60x. If we input 7 as x, we get 600 - 420 which is 180.

c. The initial value was 600, -60 is the slope.

d. As mentioned in b. of part B.

A linear function changes by a constant rate.

Two points on the table are given as:

[tex](x,y) = (0,600)\ (1,540)[/tex]

The slope (m) of the points is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{540 - 600}{1-0}[/tex]

[tex]m = \frac{- 60}{1}[/tex]

[tex]m = - 60[/tex]

So, the slope is -60, and it represents the rate at which the amount of water changes hourly.

The function of the table is represented as:

[tex]y = -60x + 600[/tex]

So:

(a) is false, because the slope is -60

(b) is true, because y = 180 when x = 7

(c) is false, because the initial value is 600

(d) is true
