Lin rode a bike 20 miles in 150 minutes. If she rode at a constant speed, how far did she ride in 15 minutes? How long did it take her to ride 6 miles? How fast did she ride in miles per hour?

Answers

Hey there! :)

Answer:

First part: 2 miles.

Second part: 45 minutes

Third part: 8 mph.

Step-by-step explanation:

We can divide this question into 3 parts.

Begin by solving for the distance traveled after 15 minutes by creating a ratio:

(20 mi)/(150min) = (x)/(15 min)

Cross multiply:

20 · 15 = 150 · x

300 = 150x

300/150 = 150x/150

x = 2 miles.

2nd part: How long it took her to ride 6 miles.

Set up another ratio similar to the one used before:

(20 mi)/(150min) = (6mi)/(x min)

Cross multiply:

20 · x = 6 · 150

20x = 900

20x/20 = 900/20

x = 45 minutes.

3rd part:

For this part, we will need to convert from minutes to hours.

(20 mi)/(150 min)* (60 min)/(1 hr) = (1200mi)/(150hr) = 8 mi/h

Therefore, her speed is 8 mph.

What is the appropiate customary unit to measure a paper clip

Answers

Since a paperclip is extremely light, the weight of a paperclip would be measured in ounces. When thinking about weight, remember that an ounce is about the weight of a pencil, a pound is about the weight of a bag of candy, and a ton is about the weight of a truck.

Centimeters or inches would be appropriate because the size of a paperclip is very tiny.

rogers father knows that dial it up sells data plans at $16 for 2 gigabytes and ring sells data plans at $9 for 1 gigabytes

Answers

Answer:

Dial it up : ring ring

=8:9

Step-by-step explanation:

From Dial it up= $16 per 2 gb.

ratio of gb : price

2:16

can be reduced to 1:8

this means that per each Gigabyte, you pay $8.

Ring Ring has plans of $9 per 1gb

ratio of gb to price is 1:9

And the ratio between the prices

of the companies is

Dial it up:ring ring

8:9

which means that in one company you get one gb for $8, while in the other company you get the same one gb for $9.

Two Angles of a Triangle 53 and 68.What is the Measure of the Third angle?A.59
B.69
C.112
D.121

Answers

The correct answer is answer choice A, 59. The sum of the three angles of a triangle is always 180°, so, if you have two angles, all you have to do is subtract them from 180 to get the thirds angle.

180 - 53 - 68 = 59
The third angle is 59°. 

Hope this helps!

Answer:

59 degrees

Can someone please help me?

Answers

Hello,

u_(1) =2\n u_(2) =2+6\n u_(3) =2+2*6\n u_(4) =2+3*6\n...\n u_(n) =2+(n-1)**6\n u_(30) =2+29*6=176\n

Answer B
So first u have to find the nth term, here the nth term is : 6n-4
Then replace the n with term that u want so:
6(30) - 4
= 180-4
=176
So it's B
