With her new trainer, Judy now bikes at an average speed of 24.1 MPH. That is 20.5% faster than she averaged with her old trainer. How fast did she bike, on average, before training with the her new trainer?

Answer:

15.4

Step-by-step explanation:

What i did was i did it in standard form. But, what i did was the 7 x 2 which is 14 then carried the 1 to the ones place. Then, i did 7x2 + 1 to get 15. Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

Heres the work:

Step-by-step explanation:

Answer:

C, 2 1/2

Step-by-step explanation:

First, you’d cross out the 3 and the 6, simplifying the problem to 1*5/2, then you’d multiply across. This should give you 5/2, which simplifies to 2 1/2

3*5/6 = 5/2 = 2 1/2

Answer:

A

Step-by-step explanation:

multiply 3 with 5 and the dominator will say the same

answer is 2399

so yeah mhm yeah u d   u    m    b

Answer:

It is 0.23 with the 23 repeating. The decimal repeats when he divided into the same number twice.

Step-by-step explanation:

23÷99=0.232323232

Since 0.232323232 is a repeating decimal with the 23 repeating, it can be represented as 0.23 with the line over 23

Note:

Sorry for the extra words it doesn't allow me to write the vinculum (the line that indicates a number is repeating)

Answer:

-11 and (0,6)

Step-by-step explanation:

Slope is given in the equation y= mx + b, where m = slope and b = y-intercept

Slope = -11

B = (0,y-intercept) = (0,6)

Answer:

159,100 is the answer

Step-by-step explanation:

159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.

Answer:

159,100

Step-by-step explanation:

200,000 - rounded to the nearest hundred thousands

160,00 - rounded to the nearest ten thousands

159,00 - rounded to the nearest thousands

159,100 - rounded to the nearest hundreds

159,100 - rounded to nearest tens

159,095 - rounded to nearest ones

While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.

If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.

Step-by-step explanation:

The mixed number is  [tex]-14 \frac{4}{7}[/tex]

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.  

Given data ,

[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]

To solve for p ,

Multiply by  [tex]1\frac{3}{7}[/tex]  on both sides we get ,

p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]

Now , [tex]1\frac{3}{7}[/tex]  can be written as the improper fraction form as  [tex]\frac{10}{7}[/tex]

So ,

p =  [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]

p =  [tex]\frac{-102}{7}[/tex]

Now , the improper fraction [tex]\frac{-102}{7}[/tex]  can be represented by the mixed number as  [tex]-14 \frac{4}{7}[/tex]

Hence , The mixed number is  [tex]-14 \frac{4}{7}[/tex]

D

when you're doing a perpendicular line, you want the exact opposite of your original.

take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.

With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so

First, make it negative

Next, flip it around.

You get -7/2 as your slope perpendicular to your original line.

For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.

For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.

Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.

-3=4(5)+b

Now, simplify

-3=20+b

-23=b

Your example equation is now y=4x-23

Answer:

15/16 liters

Step-by-step explanation:

Let x=number of liters

Let y= container

Equation: 5/8 x = 2/3 c

Multiply both sides by 3/2 --- c = (5/8x) x (3/2)

The volume of the container is 15/16 liters

Answer:

7 dm

Step-by-step explanation:

côté = √(49 dm²)

côté = 7 dm

Answer:

50

Step-by-step explanation:

From the pattern, you can see that to get y from x, you have to multiply 5.

[tex]6*5=30[/tex]

Answer:

$301.75

Step-by-step explanation:

$296.00 + $5.75

$23.75

I had to think about that one for a minute..

First step: (16 *5.25) = 84

Second step: (84 + 296) = 380

Third step: (380 ÷ 16) = $23.75

I do hope this was the correct answer you were looking for.

First let's find the cost to make the burritos.

$1.50 + $1.00 = $2.50 needed to make one burrito.

1. To find how much money the restaurant takes in from selling 100 burritos, we can do 100*8.00 which is $800.

2. We have already found the cost of making a burrito, which is $2.50

It says to convert the cost to a negative so I guess it would be -2.50?

3. The cost of making 100 burritos can be found by doing 100*2.50 which is equal to $250. The cost of making 100 burritos is $250.

4. To find the profit, we can subtract the answers from question 1 and question 3. 800-250 would be a profit of $550. The restaurant is gaining money. The price to make the burritos is way less than the money made from selling the burritos.

Answer:

A. 8

Step-by-step explanation:

Use PEMDAS

E for exponents (4^2)/(2^1)

4^2 = 4 * 4 = 16

2^1 = 2

D for division

16/2 = 8

So the answer is A

Hi!

Let's solve it together.

4^2 is just 4x4,

4 x 4 = 16

Next, 2^1.

2^1 is just 2, so the answer is 2.

Now, we divide 16 and 2.

16 ÷ 2 = 8
