Convert the angle 0=133π/72 radians to degrees

Answer:

6/25, or 0.24

Step-by-step explanation:

There are 25 numbers from which to choose, each equally likely to be chosen.

Multiples of 4 that are between 1 and 25 are {4, 8, 12, 16, 20, 24}

There are 6 such multiples of 4, out of 25 numbers total.

Thus, the probability of choosing a number from 1-25 that is a multiple of 4 is 6/25, or 0.24.

The addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have a line graph shown in the picture.

The small arrow represents the length of 4 but as it is indicating negative direction, so we take -4

Similarly, the big arrow represents the length of 9 as it is indicating negative direction, so we take -9

The sum of the lengths:

(-9)—(-4) = -13

Thus, the addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13

x = 0.7

Step-by-step explanation:

To solve this, simply find the square root of 0.49

x^2 = 0.49

(Finding the square root will cancel out the ^2 on x, to get x alone)

x = 0.7

You can double check this too to see if this is the right answer.

Answer:

Mike is not right

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the enlarged rectangular prism

y-----> surface area of the original rectangular prism

[tex]z^{2}=\frac{x}{y}[/tex]

so

In this problem we have

[tex]z=2[/tex]

substitute

[tex]2^{2}=\frac{x}{y}[/tex]

[tex]4=\frac{x}{y}[/tex]

[tex]x=4y[/tex]

so

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

therefore

Mike is not right

Verify with an example

we have a rectangular prism

[tex]L=5\ m[/tex]

[tex]W=2\ m[/tex]

[tex]H=3\ m[/tex]

The surface area of the prism is equal to

[tex]SA=2(LW)+(2L+2W)H[/tex]

substitute the values

[tex]SA=2*(5*2)+(2*5+2*2)*3=62\ m^{2}[/tex]

If he doubles each dimension of any rectangular prism

then

the new dimensions will be

[tex]L=5*2=10\ m[/tex]

[tex]W=2*2=4\ m[/tex]

[tex]H=3*2=6\ m[/tex]

The new surface area will be

[tex]SA=2*(10*4)+(2*10+2*4)*6=248\ m^{2}[/tex]

[tex]248/62=4[/tex]

therefore

The surface area of the enlarged rectangular prism is 4 times the surface area of the original rectangular prism

So first you have to find the volume of the entire tank using the height of 6cm. Then you have to find the volume of just the water using the height of 4 cm. Then you subtract both of your volumes and that will represent the volume of the part of the tank that isn't filled with water

Answer:

432cm³

Step-by-step explanation:

First we need to find the volume.

Use the volume formula.

[tex]V=l*w*h[/tex]

Plug in the values.

[tex]V=18*12*6\\ \\ V=1296[/tex]

Now find the volume of water we filled up.

[tex]V=18*12*4\\ \\ \\V=864[/tex]

Now we can subtract to find how much more water we need.

[tex]V=1296-864\\ \\ \\V=432[/tex]

432cm³ of water is needed to fill up the tank completely.

For this case we have that by definition, the area of a circle is given by:

[tex]A = \pi * r ^ 2[/tex]

Where:

A: It is the radius of the circle.

If they tell us that the diameter is 17 inches, then the radius is 8.5 inches. Substituting:

[tex]A = \pi * (8.5) ^ 2\\A = 226,865[/tex]

If we round up, we have that the area is:

226.87 square inches

Answer:

Option C

Answer:

9.55 in

Step-by-step explanation:

The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.

Here C =30 in  =  πd, so  

d = (30 in) / π

   = 9.55 in, approx.

Answer:

d = 9.554 inches.

Step-by-step explanation:

Formula

C = 2*pi*r

r = the radius

C = the Circumference.

Givens

Circumference = 30 inches.

pi = 3.14

Solution

C = 2*pi * r

30 = (2*r) * 3.14      (you'll see why I've done that in a minute. Divide by pi.

30/3.14 = 2*r

9.554 = 2r

The diameter of the basketball = 2 * radius. So the answer for the diameter = 9.554 inches.

Answer:

-1/2

Step-by-step explanation:

To find the slope we know that:

Slope = (Y2-Y1)/(X2-X1)

Then, given the two points, we have that:

(X1, Y1) = (-2,-2)

(X2, Y2) = (2, -4)

Then:

m= (Y2-Y1)/(X2-X1) = (-4-(-2))/(2-(-2)) = -4+2/2+2 = -2/4 = -1/2

So the slope of the function that passes through those points is: -1/2

Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

[tex]f(x)=2x[/tex]

You need to:

Substitute [tex]f(x)=y[/tex] into the function:

 [tex]y=2x[/tex]

Now, you need  to solve for "x", to do this, you must divide both sides of the function by 2:

[tex]\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x[/tex]

Now, replace "x" with "y" and replace "y" with "x":

[tex]\frac{x}{2}=y[/tex]

Therefore, substituting [tex]y=f^{-1}(x)[/tex] you get:

[tex]f^{-1}(x)=\frac{x}{2}[/tex] or  [tex]f^{-1}(x)=\frac{1}{2}x[/tex]

Step-by-step explanation:

Slope of the line =-5

To get point slope form of the line , we use the point that passes through the line. LEts pick the point (2,-8)

Point slope form of a line is

[tex]y-y_1=m (x-x_1)[/tex]

(x1,y1) is (2,-8) and slope m = -5

[tex]y-(-8)=-5(x-2)[/tex]

[tex]y+8=-5(x-2)[/tex] is the equation of the line in point slope form.

20$-2$=18$

18$

She spend $18 on the swimsuit and she gets total 77.5 percent off.

Given local clothing shop is marking down all of its summer clothes by 75%.

And Sarah would like to purchase a swimsuit that is originally priced at $80.

So, the markdown price of swimsuit will be ( $80 - 75 % of $80).

Now 75% of $80 is equals to $60.

So the markdown price of swimsuit will be ($80 - $60) or $20.

Again, when she gets to the register, she signs up for a loyalty cars that saves her an additional 10%.

So 2% of $20 dollar will be $2.

Now the final markdown price of swimsuit will be ($20-$2) or $18 .

Total discount she get is of ($80 - $18) or $62.

The percent amount she gets off = [tex]\frac{62}{80} \times100%[/tex] %.

=[tex]0.775 \times100[/tex]%.

[tex]=77.5[/tex]%.

She spend $18 on the swimsuit and she gets total 77.5 percent off.

Answer:

I believe 40 is the height from which the ball was dropped

In the expression \( 40(0.75)^x \), the number 40 represents the initial height from which the ball is dropped. This initial height refers to the height of the ball above the ground before it experiences any bounces.
The expression itself describes a geometric sequence where the height of the ball after each bounce is a certain fraction of the height from the previous bounce. In this particular case, after each bounce, the ball reaches a height that is 75% (or 0.75 times) of the height of the previous bounce.
To break it down further:
- \( 40 \) is the initial height (in meters, feet, or another unit of measurement) where the ball was dropped from the top of the building.
- \( 0.75 \) is the common ratio, representing the fact that the ball loses 25% of its height with each bounce. It means that the ball only reaches 75% of the height it reached after the previous bounce.
- \( x \) is the number of bounces.
So, after the first bounce (when \( x = 1 \)), the height of the ball would be \( 40 \times 0.75 \). After the second bounce (when \( x = 2 \)), the height would be \( 40 \times 0.75^2 \), and so on for each subsequent bounce, following the pattern of a geometric sequence.

Answer: Option D

[tex]P (B | A) =\frac{4}{5}[/tex]

Step-by-step explanation:

Call A to the event in which a student advances to the second round.

We know that:

[tex]P (A) = 75\% = 0.75[/tex]

Call B the event in which a student advances to the third round.

We know that:

[tex]P (B) = 60\% = 0.6[/tex]

We then look for the probability of B given A. This is:

[tex]P (B | A) =\frac{P(B\ and\ A)}{P(A)}[/tex]

In this case, the probability of B and A is equal to the probability of B, since the students who advance to the third round also advanced to the second round before

[tex]P (B | A) =\frac{P(B)}{P(A)}[/tex]

[tex]P (B | A) =\frac{0.6}{0.75}[/tex]

[tex]P (B | A) =\frac{4}{5}[/tex]

The correct answer is B.

Plug in the corresponding numbers to the corresponding variables.

m = (9 - 4)/(4 - 4)

Simplify

m = (5)/(0)

m = undefined

Undefined is your answer, for there cannot be a 5/0. You cannot have 5 parts of nothing.

To check: 119-37=82

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

The formula of a slope:

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

We have the points (-3, -1) and (1/2, 2). Substitute:

[tex]m=\dfrac{2-(-1)}{\frac{1}{2}-(-3)}=\dfrac{3}{3\frac{1}{2}}=\dfrac{3}{\frac{7}{2}}=3\cdot\dfrac{2}{7}=\dfrac{6}{7}\\\\y-(-1)=\dfrac{6}{7}(x-(-3))\\\\y+1=\dfrac{6}{7}(x+3)}[/tex]

Convert to the standard form Ax + By = C:

[tex]y+1=\dfrac{6}{7}(x+3)[/tex]           multiply both sides by 7

[tex]7y+7=6(x+3)[/tex]              use the distributive property

[tex]7y+7=6x+18[/tex]                subtract 7 from both sides

[tex]7y=6x+11[/tex]             subtract 6x from both sides

[tex]-6x+7y=11[/tex]
