Answer:72

Step-by-step explanation: Because angles on a straight line add up to 180 degrees, 4x+6x=100 would give you the desired x. Solving this, x=18. Multiplying x by 4 gives 72. Hope this helps! (Could I please have brainliest?)

Answer:

A)72

Step-by-step explanation:

They have essentially divided up the line 2 different ways, into 2 parts and into 10 parts. The 2 parts is from 1 and 2 and then the 10 parts is because of the ratio 4-6. The 2 parts are not equal because one of them is 4 parts of the line and the other is 6, if we put that together we get the 10 equal parts of the line. A line is equal to 180 degrees meaning that we can divide that my 10 to figure out how much each part is equal to 180/10 is 18 so each of the 10 parts is equal to 18. We are looking for <1 which it says is equal to 4 parts so we will multiply 4 by 18 to get how much it is. 4 times 18 is 72 so the answer is A

I hope this helps and please don't hesitate to ask if there is anything still unclear!

A bucket holds b liters of water. But a jar holds 8 fewer liters than the bucket. How many times can the bucket hold than the ja

kykrilka [37]

Answer:

b / (b - 8)

Step-by-step explanation:

Given that :

Litres of water held by bucket = b

Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8

The number of times bucket can hold than jar is :

Litres held by bucket / litres held by jar

b / (b - 8)

A train travels 80 miles per hour. If its speed remains the same, how far will the train have gone in 90 minutes?

Nataly_w [17]

Hello! So, the train travels 80 miles in an hour. 90 minutes is equivalent ot 1 ½ hours. In case you don't know, ½ of 80 is 40. To find the distance gone in 90 minutes, we can just add 80 and 40. 80 + 40 is 120. Another way to solve it is to multiply 80 by 1.5 and you would still get the same answer. There. The train will have gone 120 miles in 90 minutes.
