Answer:

50cm of scarfs is equal to 2.5 nights of knitting.

Step-by-step explanation:

20cm= 1 night

10cm= 1/2 or 0.5 a night

40cm= 2 nights

50cm=2.5 nights

Answer:

Step-by-step explanation:

I think you mean 0.5 in:20 mi

2 in × (20 mi)/(0.5 in) = 80 mi

2 inches on the map corresponds to 80 miles.

8 miles is the real distance that corresponds to the 2 inch map measurement.

We can utilize the map's scale to get the actual distance that corresponds to the 2 inch map distance.

The scale is presented as 0:5 in:20 mi, which implies that each 5 inches on the map corresponds to 20 miles in actual travel distance.

Let's establish a ratio to determine the actual distance:

5/2 = 20/x

If we cross-multiply, we obtain:

5x = 2(20)

5x = 40

When we multiply both sides by 5, we get:

x = 40 / 5

x = 8

Therefore, 8 miles is the real distance that corresponds to the 2 inch map measurement.

Answer:

it is 12:20

Step-by-step explanation:

Answer:The equation would be 230 = 25y + 10x + 1x or 230 = 25y + 11x

You would then need to solve for x and y, which I forget how to do with 2 variables but since we're working with small numbers what I would do is continuously subtract 25 from 230 until the remainder is divisible by 11.

230 - 25*7 = 55 = 11*5

x = 5

Ok, adding the equation 2x+y = 17 you will now be able to solve for the two variables using a system of equations.

yes, you can come up with an equation. actually, you can come up several equations to generate a system of equations.

your first equation is correct.

(1) 25q + 10d + 1p = 230

now, you're told that the number of dimes equals the number of pennies. that just means, in symbols:

(2) d = p

finally, you're told that you have 17 coins in all, i.e.:

(3) q + d + p = 17

you now have three equations and three unknowns. use (2) to reduce (1) and (3).

(1′) 25q + 11d = 230

(3′) q + 2d = 17

now solve for the three variables.

Answer:

7 quarters

Step-by-step explanation:

We can use the guess method.

17 coins altogether, and as many dimes as pennies.

The number of quarters must be odd. When you subtract an odd number of quarters from 17, you get an even number which will divide by 2 evenly giving you the same number of pennies and dimes.

Start with a guess of 7 quarters.

17 - 7 = 10

7 quarters + 5 pennies + 5 dimes have a value of $2.30

Wow, I got it with the first guess.

Answer: 7 quarters

Answer:

a) d = 3.6t

b) 10.8 miles

c) 1.2 hours

Step-by-step explanation:

For part a:

Slope of a line: y = mx + b

In this case, the equation would be: d = mt,

where m represents the speed Caden is walking at.

Note: b = 0 in this case because when Caden starts walking on the treadmill, he hasn't really covered any distance yet.

Therefore, plugging in a speed of 3.6 miles per hour, the equation is:

d = 3.6t

For part b:

This is a simple instance of plugging in 3 hours for our t value.

Therefore, d = 3.6 (3)

d = 10.8 miles

For part c:

In this case, we are given that d = 4.32 miles.

Therefore, 4.32 = 3.6t

Dividing both sides by 3.6, we get

t = 1.2 hours

Answer:

The answers C if you plug in the answer and re-write it 11.3.04 is correct.

Answer:

y=3/4x+10

Step-by-step explanation:

lts take two points

(-4,7)

(0,10)

so slope is 3/4

so 3/4*-4+b= 7

-3+b=7

b=10

y= 3/4x+10

if my answer helps please mark as brainliest.

Answer:

y = 3/4 x + 10

Step-by-step explanation:

the b is 10 because y is 10 when x is 0

to find the x, plug in any variable from the chart into the equation y=mx+b

i used (-4, 7), so the equation would be 7=m(-4)+10

solve for x

-4m=7-10=-3

m=3/4

Hi there

Step-by-step explanation:

What exactly is the question being asked?

The song is 4 times as likely to be country than it is to be blues.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Total number of songs = 32 + 48 + 12 + 8 = 100

If she randomly plays a song from this list,

Probability that the song is country = 32/100 = 8/25

Probability that the song is rap = 48/100 = 12/25

Probability that the song is hip hop = 12/100 = 3/25

Probability that the song is blues = 8/100 = 2/25

Probability of country = 8/25 = 4 (2/25) = 4 times probability of blues.

Hence the correct option is B. The song is 3 times as likely to be country than it is to be blues.

B The song is 4 times as likely to be country than it is to be blues.

Answer:

12 minutes

Step-by-step explanation:

First figure out how long it took her to run 1/3 of the mile.

2/3 ÷ 2 = 1/3

8 ÷ 2 = 4

So she ran 1/3 in 4 minutes.

Multiply that answer by 3 to get your full mile.

1/3 * 3 = 1 mile

4 * 3 = 12 minutes

Answer:

12 minutes

Step-by-step explanation:

In my brain, I divide the run into three parts (because the fraction has a base of three). If I ran two parts of those three in eight minutes, then to find the amount of time it took to run one part (cause that's how much we need to add), I need to divide the time by two, and then add it to the 8 minutes. When the math is done, a third of a mile can be ran in 4 minutes, which means that an entire mile can be ran in 12 minutes.
