3/5 = blue shirts

5/8 of 3/5 = on sale blue shirts

1/3 of 5/8 of 3/5 = medium on sale blue shirts

‘Of’ can be replaced by multipication symbols.

1/3 • 5/8 • 3/5

1/3 • 3/5 = 3/15 (or 1/5)

3/15 • 3/5 = 9/75 (or 3/25)

9/75 of the shirts are medium, on sale, and blue. If you wanted to simplify this it would just be 3/25 of the shirts.

Answer:

Rational

Step-by-step explanation:

Any number you can write out completely, or that has a repeating decimal fraction, is a rational number. 291.7 is the entire number, so is rational.

she needs to count how much 90% is so

85.00 times 90%

or 8500 times 0.9

Answer:

B) .95(53.75)

Step-by-step explanation:

5% is equal to 0.05. So the following expressions are equivalent.

5% × 53.75 = 0.05 × 53.75

To find the final price, she first takes the 5% and then subtracts the amount from 53.75. That is,

53.75 - 5% × 53.75 = 53.75 - 0.05 × 53.75

We can take out the common factor 53.75

53.75 . (1 - 0.05) = 53.75 . 0.95 = 0.95 . 53.75 = 0.95 (53.75)

since both points have a y- coordinate of zero, this is a horizontal line parallel to the x- axis

hence slope = 0

We want to find the slope of a line given that we know two points on the line.

We will see that the slope of the line is 0.

Generally, if we know that a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of that line is given by:

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

Here we know that the line passes through (-4, 0) and (2, 0) then the slope will be:

[tex]a = \frac{0 - 0}{2 - (-4)} = 0[/tex]

The slope is equal to zero, meaning that this is a horizontal line (as you can see in the points, the y-component does not change).

C'(2, 3 )

under a counterclockwise rotation about the origin

a point (x, y ) → (- y, x ) hence

C(3, - 2 ) → C'(2, 3 )

Answer:

C' (2, 3)

Step-by-step explanation:

Remember that when you are rotating something 90 degrees and counter clockwise you just need to interchange the X and Y values, and change the value of the new X to a negative position because it woul be located in the second quarter:

(x,y) rotated 90º counter clockwise= (-y,x)

(3,-2)=(-(y),x)=(-(-2),(3)=(2,3)

B) x = -1 and x = 6

Step-by-step explanation:

The values that must be excluded from the domain are the values for which f(x) is undefined. Those values are the ones that make the denominator be zero.

We can find the zeros of the denominator by factoring.

... x² -5x -6 = (x +1)(x -6)

The product is zero when either factor is zero, so when x=-1 or x=6.

The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) Of course "per" means "divided by".

speed = distance/time

speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h

Logan's average speed is 2.25 kilometers per hour.

y = 4

first note that the right side simplifies to 12, equation can be written

[tex]\frac{2y+1.6}{0.8}[/tex] = 12 ( multiply both sides by 0.8 )

2y + 1.6 = 9.6 ( subtract 1.6 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4

Hey there!!

We have:

... (2y+1.6)/0.8 = 30/2.5

... (2y+1.6)/0.8 = 12

Multiplying 0.8 on both sides.

... (2y+1.6) = 12×0.8

... 2y+1.6 = 9.6

Subtracting 1.6 on both sides:

... 2y = 9.6-1.6

... 2y = 8

Dividing by 2 on both sides:

... y = 8/2

... y = 4

Hence, the required answer is 4.

Let the basic calendars be = x

Let the deluxe calendars be = y

Total calendars are = 72 , so equation becomes:

[tex]x+y=72[/tex]  .............(1)

Cost of 1 basic calendar = $10

So, cost of all basic calendars will be = 10x

Cost if 1 deluxe calendar = $15

So, cost of all deluxe calendars = 15y

As given, the number of deluxe calendars must be greater than or equal to 3 times the number of basic calendars, the equation becomes

y=3x ...............(2)

Putting the value of y from (2) in (1)

[tex]x+y=72[/tex]

[tex]x+3x=72[/tex]

[tex]4x=72[/tex]

x=18

As, y=3x

y=[tex]3\times18=54[/tex]

So we have 18 basic calendars and 54 deluxe calendars.

Cost of 18 basic calendars will be= [tex]18\times10=180[/tex]

Cost of 54 deluxe calendars will be = [tex]54\times15=810[/tex]

So total amount is = $990

Step-by-step explanation:

Let 'x' be the cost of remote keyless entry.

And [tex]8x[/tex] be the cost of 4-way power front passenger seat.

Total cost = destination charge + title fee + taxes

So we have the equation:

[tex]20,000 = (17,980+x+8x)+0.072(17,980+x+8x)[/tex]

Now solving for 'x', we get:

[tex]20,000 = (17,980+9x)+0.072(17,980+9x)[/tex]

[tex]20,000=17,980+9x+1294.56+0.648x[/tex]

[tex]20,000=19274.56+9.648x[/tex]

[tex]725.44=9.648x[/tex]

[tex]x=\frac{725.44}{9.648} =75.19[/tex]

Therefore, the cost of remote keyless entry is $75.19.

The law of cosines can be helpful here. The largest angle (C) will be opposite the longest side (c). That law tells us ...

... c² = a² + b² -2ab·cos(C)

Then

... cos(C) = (a² +b² -c²)/(2ab)

We don't actually need the angle. We only need to know the sign of the cosine.

... cos(C) = (7² +15² -17²)/(2·7·15) = -15/210 . . . . negative sign, so C > 90°

Answer:

204 students

just do 7140/35= 204

Step-by-step explanation:

Number of students who can get craft sticks are 204 .

To determine how many students can get craft sticks from the teacher, we need to divide the total number of craft sticks by the number of craft sticks each student needs.

Step-by-Step Solution

The total number of craft sticks is 7,140.

Each student needs 35 craft sticks.

To find out how many students can get the craft sticks, divide the total number of craft sticks by the number of craft sticks each student needs:

7,140 ÷ 35 = 204

Therefore, 204 students can get craft sticks from the teacher.

Estimation and Checking

To estimate the quotient, you can round the numbers to make the division easier. For example, round 7,140 to 7,000 and 35 to 30:

7,000 ÷ 30 ≈ 233.33

This estimation tells us that our division answer is reasonable, falling close to this rounded solution.

To check the division, multiply the quotient by the divisor and see if you get the original dividend:

204 × 35 = 7,140

Since the result matches the original number of craft sticks, the answer is verified as correct.

Here we need to find the average rate of change of [tex]f(x)[/tex].

Now,

[tex]f(x)=-2x^2+4x+2[/tex]

Let us find out the value of [tex]f(x)[/tex] at the point [tex]x=1.2[/tex].

Plugging [tex]x=1.2[/tex] in the equation we get:

[tex]f(1.2)=-2(1.2)^2+4(1.2)+2=-2\times 1.44+4.8+2=-2.88+4.8+2=3.92[/tex]

So,

[tex]f(1.2)=3.92[/tex]

Now calculating the value of [tex]f(x)[/tex] at [tex]x=3.8[/tex].

[tex]f(3.8)=-2(3.8)^2+4(3.8)+2=-2(14.44)+15.2+2=-28.88+15.2+2=-11.68[/tex]

So,

[tex]f(3.8)=-11.68[/tex]

Now that we have the values of the function at two distinct points, we can find the average by using the formula given below:

[tex]Avg= \frac{sum}{n}[/tex], where 'n' represents the number of values and that is two in our case and sum represents the sum of the values of the function.

Therefore,

[tex]Avg= \frac{3.92+(-11.68)}{2} =\frac{-7.76}{2} =-3.88[/tex]

So, the average rate of change of the function [tex]f(x)[/tex] from 1.2 to 3.8 is [tex]-3.88[/tex].
