you are biking at a speed of 18mph. you are 3 miles behind your friend, who is biking at a speed of 12mph. write and solve an equation to find the amount of time it takes for you to catch up to your friend

Answers

Answer 1
distance = velocity x time
Assume the distance moved by your friend is "d" and that the time taken for you to catch to him is "t"

you are moving with a velocity of 18 mph and your friend is moving with a velocity of 12 mph.
distance covered by your friend (d) = 12t miles ......> equation 1

If you add 3 to your rate, your distance will be the same as your friend's. This means that:
 d+3 = 18t miles ......> equation 2

Substitute by 1 in 2:
12t + 3 = 18t
3 = 6t
t = 0.5 hours
This means that you will catch up to your friend in half an hour.

How many meter of cloth is needed if Aling Luding to make 25 pillowcase if each pillowcase needs 95 cm long cloth?

Answers

23.75
this is because there would be 2375cm if you didn't convert it into meters
 

Aling Luding will need 23.75 meters of cloth to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth. We convert the total centimeters to meters by dividing by 100.

To calculate the total amount of cloth Aling Luding needs to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth, we need to perform a simple multiplication. We multiply the number of pillowcases by the length of cloth needed per pillowcase.

Therefore, the calculation will be:

25 pillowcases  imes 95 cm per pillowcase = 2375 cm.

However, we often measure fabric in meters, so we need to convert centimeters to meters. There are 100 cm in a meter, so:

2375 cm \/ 100 = 23.75 meters.

So, Aling Luding needs 23.75 meters of cloth in total to make 25 pillowcases.

What's the answer to this question ? I've been really confused for the past 20 minutes

the hint tells you s is sqrt(a)

 the question tells you a = 570025

so side = sqrt(570025)

 plug that into your calculator to get:

21) Each side is 755 in
To do this all you'll need to do is find the root of 570,025, which is 755

336.752 divided by 31

Answers

it    is   originally 10.829677419 so rounding to the nearest tenth would be 10.9

Answer:

Round to the nearest tenth  336.752 divided by 31 is 10.9

Step-by-step explanation:

Consider the provided information.

336.752 divided by 31

This can be written as:

336.752 ÷ 31

Divide the number as shown:

[tex]\frac{336.752}{31}[/tex]

[tex]10.862968[/tex]

Now we need to round it to the nearest tenth.

According to the place value:

Tens   Ones   Decimal point   Tenths   Hundredths

 10         1                    .                0.1           0.01

According to place value tenths place is just after the decimal point so round the number to just after decimal point.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, round it up by one number.

Here, the number at the hundredths place is 6 so round it up.

Thus, the  round to the nearest tenth is 10.9

55 miles per hour write a algebric expression to show how far the car will travel in a certain number of hours

Answers

55miles in an hour  times x( # of hours that are unknown)
Final answer:

The algebraic expression for the scenario is 'd = 55t', where 55 (miles per hour) is the constant, and 't', which represents time in hours, is the variable. This expression is used to calculate the distance traveled by a car.

Explanation:

The subject of your question is algebra, particularly involving the concept of linear equations. In this scenario, you're looking to determine how far a car will travel given a certain speed and number of hours. Your constant in this case will be the speed of the car, which is 55 miles per hour. The variable is the time in hours, which we can denote by 't'. Hence, the algebraic expression representing this scenario would be d = 55t where 'd' represents the distance traveled by the car. The distance is calculated by multiplying the constant speed by the variable time.

a digital scale measures weight to the nearest 0.2 pound. which measurement shows an appropriate level of precison for the scale?

A. 130.4 pounds

B. 125 pounds

C.120 pounds

D. 124.75 pounds


Answers

I think it would be A. 130.4 if it is measuring to the nearest 0.2 pound

Answer:

130.4 pounds

Step-by-step explanation:

The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.

Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.

Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.
