Number 14, please...

1 answer:

5 0

So you know that the area is greater than or equal to 60. Since 1/2 b x h is area, .5 x 12 x height (c) is greater than or equal to 60. Then solve, so .5 x 12 is 6, so 6c is greater than or equal to 60. then divide both sides by 6 and you end up with c is greater than or equal to 10

Suppose that the first team member in a 3-person relay race must run 2 1/4 laps, the second team member must run 1 1/2 laps, and

Kisachek [45]

You need to add up all 3 mixed numbers to find the total laps.

2 + 1/4 + 1 + 1/2 + 3 + 5/8 =

(2 + 1 + 3) + (1/4 + 1/2 + 5/8) =

6 + (2/8 + 4/8 + 5/8) =

6 + (11/8) =

6 + (1 + 3/8) =

7 3/8 laps

Please help! A parallelogram has an area of 396 square centimeters and a height of 18 centimeters.

frosja888 [35]

The area formula for a parallelogram is base*height=area. Make an equation. You know the area and the height, so plug that into the equation, and you get x*18=396. Solve for x by dividing 396 by 18 and you get 22. So, the base is 22cm.

what is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the point (15

ohaa [14]

The slope of the given line is the coefficient of x, 3/5. The slope of the perpendicular line will be the negative reciprocal of that: -1/(3/5) = -5/3.

The point-slope form of the equation for a line of slope m through point (h, k) can be written ...

... y = m(x -h) +k

For your point and the slope found above, this becomes

... y = (-5/3)(x -15) -5

When x=0, this is

... y = (-5/3)(-15) -5 = 20

The y-intercept is 20.
