Answer:

hope it helps

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

The way you solve this is by creating an inequality of

30          15

----     =   ----

100          x

So you cross multiply which would give you 30x = 1500, then you divide by 30 on both sides leaving you with 50. If you want to check it, you can then multiply 50 by .30 which would give you 15.

Question 3 What is the slope of the line that passes through the points (0.-7) and (-4, 3)? 0 -3/11 O -2/5 À O -5/2 0 10/4 Question 4 ​

Answers

Answer:

Gradient = Change in y / Change in x

Gradient = (-7-3) / (0-4)

Gradient = -10/-4

Gradient = 2.5

So the answer is 10/4, which is 2.5

The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.

What is a slope?

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.

Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 3 - (-7) / ( -4 - 0 )

Slope = 10 / -4

Slope = -5 / 2

I think it's 1800 Degress

Step-by-step explanation:

If the CD rotates 300 times per minute, we know that equals 300 rotations/60 seconds

That ends up being 5 rotations per second.

Since we know that a full rotation is 360 degrees, then it should equal 1800 degrees.

Answers

Answer:

Diameter of the ball = 8 inches

Radius of the ball (r) = diameter ÷ 2 = 8 ÷ 2 = 4 inches

π = 3.14

Surface area of the ball (A) is the same as the surface area for a sphere = 4 π r² = 4 × 3.14 × 4² = 200.96 inches²

Using the formula of volume of sphere, the volume of the rubber ball is 14[tex]inches^{3}[/tex] approximately.

What is the volume of sphere?

The volume of sphere is the amount of space occupied, within the sphere.

Diameter of sphere = 3 inches

Radius of sphere = 3/2 = 1.5 inches

Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex] = [tex]\frac{4}{3}*\frac{22}{7}*1.5^{3}[/tex] = 14.13 [tex]inches^{3}[/tex]

Expanding this, we have ...

  y = mx +(k -mh) . . . . slope-intercept form

standard to slope intercept form

Answers

Answer:

[tex]y=\frac{5}{3}x+8[/tex]

Step-by-step explanation:

Remember, slope intercept form is:

y = mx + b

where m is the slope and b is the y-intercept.

To get the given equation into slope-intercept form, we would have to first solve for y in terms of x.

10x - 6y = -48

Subtract 10x from both sides.

-6y = -48 - 10x

Multiply both sides by -1.

6y = 10x + 48

Divide both sides by 6.

[tex]y=\frac{5}{3}x+8[/tex]

And now, looking at the equation that we found and the equation for slope-intercept form, we can see that we have found the equation for 10x - 6y = -48 in slope-intercept form.

Step-by-step explanation:

In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.

Answer:

Step-by-step explanation:

To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8


At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:

Answers

Answer:

C(p) = 0.25p + 5

Step-by-step explanation:

$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.

m = slope, b = y-intercept

C(p) = mp + b

C(p) = 0.25p + 5

Which expression is equivalent to sin(1.8x) sin(0.5x)

Answers

Answer: 0.5(cos 1.3x − cos 2.3 x)

Step-by-step explanation:

Hey there!

In trigonometry which relates the sides and angles of the triangle, there is an identity which states that,

                    (sinA) (sinB) = 0.5(cos (A − B) − cos (A + B) )

In this item, our A and B are 1.8x and 0.5x, respectively.  

Substituting,

                  sin(1.8x)sin(0.5x) = 0.5(cos (1.8x − 0.5x) - cos(1.8x + 0.5x))

                  sin(1.8x)sin(0.5x) = 0.5(cos 1.3x − cos 2.3 x)

Yesterday, Kate gave exactly fourteen haircuts
and made $50.00. If she charged $5.00 for adults'
haircuts and $2.50 for children's haircuts, how
many children's haircuts did she give?
A) 5
B) 6
C) 7
D) 8

Answers

Answer:

D) 8

Step-by-step explanation:

8 x 2.5 = 20

and the rest is adult haircuts

6 x 5 = 30

Answer:

D) 8 Children’s Haircuts

Step-by-step explanation:

Let a represent the amount of adult haircuts and c represent the amount of child haircuts.

We know that she gave exactly 14 haircuts. So:

[tex]a+c=14[/tex]

We also know that she made $50.00. Therefore, the price of each haircut times their respective amounts will total $50. So:

[tex]5a+2.5c=50[/tex]

This is now a system of equations.

We can solve this using substitution. From the first equation, let’s subtract c from both sides:

[tex]a=14-c[/tex]

Now, we can substitute this into the second equation for a. This yields:

[tex]5(14-c)+2.5c=50[/tex]

Distribute:

[tex]70-5c+2.5c=50[/tex]

Combine Like Terms:

[tex]70-2.5c=50[/tex]

Subtract 70 from both sides:

[tex]-2.5c=-20[/tex]

Divide both sides by -2.5:

[tex]c=8[/tex]

Therefore, Kate gave 8 children’s haircuts.

This means that she gave [tex]14-8=6[/tex] adult haircuts.

So, our answer is D. She gave 8 children’s haircuts.
