For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14

Answers

Answer:

A. M=6

Step-by-step explanation:

Basically, this question is asking you to find m if 4/16 = m/24.

First, 4/16 can be simplified to 1/4. This will make it easier to solve.

You now have 1/4 = m/24.

Multiply both sides by 24 to get 24/4 = m.

Simplify to get m = 6.

is palpatine the strongest sith

Answers

Answer:

One may think that he is the most powerful Sith Lord, and on some levels this is correct, but that title falls to another, even more powerful Sith Lord. That is Jar Jar Binks. He possesses the power to wipe out entire universes without blinking an eye. Jar Jar is an entity that was here before the universe was created. He made God. He even made Shaggy in his image so that he could have a set of eyes on Earth. He needed a right hand man to corrupt humanity at its source. Some might say that Jar Jar is the true form of evil, but I refute that claim with an argument of my own. Jar Jar Binks may have destroyed countless lives, but he did so in order to keep the balance of the universe, and for that, I thank him. All hail Jar Jar.

24 is 3/4% of what number

Answers

24 is 3/4 of the number 32

Answer:

32

Step-by-step explanation:

Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)

So our simple equation looks something like this:

[tex]24= x *\frac{3}{4}[/tex]

So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.

So: [tex]24 * \frac{4}{3} = x[/tex]

Doing the simple math we get:

[tex]24 * \frac{4}{3} = 32[/tex].

32 is your answer.

Hope this helps and have a nice day! Sorry I'm not great at explaining it!

Point A is located at (-2,-2). Plot all of the points 3 units away that have the same y-coordinate as point A.

Answers

Answer:

Points are ( 1, -2) , (-5, -2)

Step-by-step explanation:

the given point is A ( -2, -2)

If we fix the y coordinate , then we can change only x coordinate

As we want point 3 unit away

So, add 3 and subtract 3 from x coordinate to find the resultant point

If we add 3 to x coordinate , we get

-2 + 3 = 1

So the point be ( 1, -2)

If we subtract 3 to x coordinate , we get

-2 - 3 = -5

So the point be ( -5, -2)

The diagram below models the diameter of the bicycle wheel
21.75
Which of the following is closest to the distance of the length when the bicycle wheel
makes 1 revolution?
A7 inches
B 25 inches
C34 inches
D69 inches


Can anyone help me!!

Answers

Answer: (21.75 / 2) * 2 * pi = 68.42...in, answer D.

Explanation: one revolution from a wheel will be a 360 degree rotation, meaning that if you had laid your finger on the outside of the wheel as it made its full rotation, your finger would have touched the entire circumference of the wheel. Thus, we can represent the length of 1 revolution as the circumference. Thus we take the diameter, and divide it by 2 to get the radius. Then we simply multiply by 2 * pi * r (r = radius). This is the formula for the circumference of a circle.

Step-by-step explanation:

In circle S: XB and XD are tangents at B and D

then SB perpendicular to AX and SD perpendicular to XC

In triangle SDX:  SD = 12 and SX =20 by using Pythagoras Theorem

XD = XB  tangents to circle S from point X

XA = XC tangents to circle R from point X

then BA = DC = 15

then XC = XD + DC = 16 + 15 = 31

Tan =

Answers

Answer:

-4/3.

Step-by-step explanation:

cos O = 3/5

Using Pythagoras to find the length of the side opposite  the angle O:

As the  cos of O is adjacent/ hypotenuse,  Hypotenuse = 5 , adjacent side = 3 so

opposite side. = sqrt(5^2 - 3^2) = sqrt 16

= 4.

Now the tangent is negative in Q IV so

tan O =  opposite / adjacent side = -4/3

A new bank customer with ​$4,000 wants to open a money market account. The bank is offering a simple interest rate of 1.2​%.

a. How much interest will the customer earn in 30 ​years?
b. What will the account balance be after 30 ​years?

Answers

Answer:

Interest: $1440

Total Account Balance: $5440

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.2%/100 = 0.012 per year,

then, solving our equation

I = 4000 × 0.012 × 30 = 1440

I = $ 1,440.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 1.2% per year

for 30 years is $ 1,440.00.

The simple Interest is $1440 and the total Account Balance: $5440.

What is simple interest?

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.

First, converting R percent to r a decimal,

r = R/100 = 1.2%/100 = 0.012 per year,

Then, solving our equation,

I = 4000 × 0.012 × 30 = 1440

I = $ 1,440.00

The simple interest accumulated,

on a principal of $ 4,000.00

at a rate of 1.2% per year

for 30 years is $ 1,440.00.

Therefore, the simple Interest is $1440, and the total Account Balance: $5440.
