Answer:

i remember learning this you have to enter 4 into the code in how you find radius

Step-by-step explanation:

so if it's radius I'm pretty sure it'll be 8/3.14x2

1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5

2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

Answer:

6

Step-by-step explanation:

Let Nancy's age be represented by n

Because Isabel is 3 times as old as Nancy, her age would be represented by 3n

Sum of their ages = 24

n + 3n = 24

4n = 24

divide both sides of the equation by 4 to determine n

n = 6

Answer:

B. 102 cm

Step-by-step explanation:

The first step would be to find the area of the whole figure and subtract the white area off.

So, to do that simply multiply the length x width to get the area of the whole figure.

20 x 6 = 120(area of the whole figure)

Next, 20-11 = 9 is the length of the figure and because the square has a side length of 3, the other side would also have to be 3.

3 x 3 = 9(area of the smaller square.

9-3=6

6-3=3

Area of triangle = Base x Height Divided by 2.

So, 3x6=18/2=9

9+9=18

Finally, subtract 18(total area of white smaller shapes) from 120 and you will get the final answer

102 cm.

Answer:

She lost $54

Step-by-step explanation: Just trust me

If it was right mark as Brainleist

Answer:

The answer is $54.00.

Step-by-step explanation:

To find the how much money, we just need to multiply 600 by 0.09.           600 x 0.09 = 54.

  600

x 0.09

------------

 5400      

Now you just move the decimal 2 places to the left, and you get 54.00! The answer is $54.00. Hope this helped! :]

Answer:    0.25 as a decimal

Answer:

0.25

Step-by-step explanation:

You can think of fractions as smaller increments of money.

2/4=0.5

3/4=0.75

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.

Imagine this happening:

1$

Uses 1/4

So... Let's look at what I've given you.

2/4=0.5

3/4=0.75

Well, let's stretch some things a liiiiitle bit.

Bob has a dollar bill blah blah...

We get to 1/4.

Le's make that 2/4.

2/4 is 0.5

So... By stretching the truth

We can infer that

If we put 1/4 back

(Oh no now the word problem creators are mad at me ;) lol)

Anyways, we can infer that by putting 1/4 back

That since 3/4 is 0.75

Then what's connected to 0.5 and 0.75?

The answer, my friend,

Is 0.25

Answer:

1. 6.75x or (6.75, 1)

2. He buys 9 sandwiches.

Step-by-step explanation:

For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x

For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.

I hope this helps :)

how is this  a mathematical question???

Answer:

-7y > 161

7y < -161

y < -23

7y > -161

y > -23

So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.

Answer: 462

Step-by-step explanation: substitute 72 for x in the equation 6(72)+30

Answer:

A

Step-by-step explanation:

in x<-4 the derivative is positive so the function is increasing.

in x>-4 the derivative is negative so the function is decreasing

increasing in (-infinity,-4)

decreasing in (-4,infinity)

Step-by-step explanation:

using substitution, replace y in 3x+y=-12

3x-2x-7=-12

x-7=-12

x=5

y=-10-17

y=-17

x=5

Answer: Krista's  drawing would have a base length of 2 and 1/4 inches and a height of 7/8 inches

Step-by-step explanation: First you do 6 divided by 3 which is 2 then you make 3/4 in twelfths and you get 3/12, then you simplify that into 1/4. Then

you combine those and get a base length of 2 and 1/4 inches.

Next, you do 2 and 5/8 divided by 3. Since 3 is less than 2 your answer would have to be less than 1. What i would do is make 2 and 5/8 into a fraction, which would be 21/8. then to make it easiest you multiply that by 1/3. which would equal 21/24. and then you simplify by dividing that by 3. Which would give you 7/8, which would give you your answer.

So the final answer would be a base length of 2 and 1/4 inches and a height of 7/8 inches.

Answer: 19

Step-by-step explanation:

1) You combine like terms with all the angles

Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93

2) You set up an equation using the formula for the sum of the interior angles

Ex. 33x + 93 = 180(n - 2)

3) Since a hexagon has 6 sides, n is 6

Ex. 33x + 93 = 180(6 - 2)

4) Solve like a regular equation

Ex. 33x + 93 = 180(6 - 2)

33x + 93 = 720

- 93 = - 93

33x = 627

- Divide 627 by 33

x = 19

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

[tex]\sigma=1150[/tex]

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

⇒      [tex]=\frac{1150}{\sqrt{500} }[/tex]

then,

⇒      [tex]=P(-1.94<Z<1.94)[/tex]

⇒      [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]

On using the table of P, we get

⇒      [tex]=0.9738 - 0.0262[/tex]

⇒      [tex]=0.9476[/tex]
