What is the answer to 4 ⋅ (−6)

If x varies directly as y, then what is y when x = 4, knowing that x = 60 when y = 5?

Basile [38]

Answer: The answer would be 1/2

Step-by-step explanation:

Y varies DIRECTLY as x. Find the constant of variation, k, if y = -5x

The first sentence is there for information, the constant is a number( 1,2,3...so on) , so the only number is -5

It is a linear equation meaning equation of a straight line.

its form is y= mx+b, where m is the slope of the line, b is the y intercept when x=0. these info you have to memorize like your life depend on it.

next, y varies directly as x. If y = 15 when x = 60, find y when x = 100

if y= 15, when x=60, then there is a number m such that m*y= 60

or m= 60/y= 60/15 =4

so the equation is y=4x. in this cause, the b=0

so when x=0, y=0

The distance a car travels at a constant speed varies directly as the time the car spends traveling. If a car traveled 105 miles in 3 hours, how far could the car travel in 5 hours?

remember that distance = speed times time.

or d=Vt

so car goes 105 miles on 3 hours

how far it goes in one hour?

if you know that, then you can tell how far it goes in 5 hours.

Hope I made it non tough enough

A basketball team played six games. In those games, the team won by 7 points, lost by 7, won by 8, won by 9, lost by 4, and won

Gemiola [76]

Based on the difference in scores for the basketball team over the six games, the mean difference in scores was 3

<h3>How to find the mean difference in scores?</h3>

The basketball team had 6 games and in these games, their scores were listed as differences in game scores.

The mean of these differences in scores can be found by adding the differences where they won and subtracting the differences where they lost and then dividing by the number of games:

The mean difference in game scores is:

= (7 - 7 + 8 + 9 - 4 + 5) / 6

= 18 / 6

= 3

Step-by-step explanation:

The directions in which the grasshopper can jump are;

One block north and one block west

By counting, we have;

The number of possible ways are through blocks

1) 1, 2, 5, 6, 8, 10

2) 1, 2, 5, 6, 8, 9

3) 1, 2, 5, 6, 7, 9

4) 1, 2, 3, 6, 8, 10

5) 1, 2, 3, 6, 8, 9

6) 1, 2, 3, 6, 7, 9

7) 1, 2, 3, 4, 7, 9

8) 15, 14, 16, 12, 11, 10

9) 12, 13, 16, 12, 11, 10

Therefore, there 9 ways the grasshopper can reach the desired destination.

A bottle of medicine contains 40 doses. How many doses are in 3 1/3 bottles?

sdas [7]

Hi there! So, there are 40 doses in 1 bottle. To find out the number of doses in 3 1/3 bottles, we have to multiply both numbers together. 3 1/3 as an improper faction is 10/3. 40/1 * 10/3 is 400/3 or 133 1/3 in simplest form. There are 133 1/3 doses of medicine in 3 1/3 bottles.
