Answer:

The equation of this line would be y = -8

Step-by-step explanation:

Since y = 9 is a horizontal line, the parallel line must also be horizontal. All horizontal lines can be written as y = (a number). That number can be found as the y-coordinate in the ordered pair, which is -8.

y = -8

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr

Alex Ar [27]

Answer:

3/68

Step-by-step explanation:

Given

Total 17 marbles
4 - blue marbles
6 - green marbles
2 - red marbles
The rest - yellow marbles

Probability of drawing red first:

P(red) = number of red / total number = 2/17

Probability of drawing green second, without replacement:

P(green) = number of green / number left in the bag = 6/16 = 3/8

Probability of red and green in order:

P = P(red)*P(green) = 2/17*3/8 = 3/68

Adam, Matt, and Clinton sold sandwiches in the ratio of 2:7:3 to raise money their basketball team. Matt sold 91 sandwiches. How

zavuch27 [327]

Answer:

156

Step-by-step explanation:

Let,

Sandwiches sold by Adam, Matt and Clinton = 2x, 7x and 3x

Total sandwiches = 2x + 7x + 3x

=> 12x

But its given that Matt sold 91 sandwiches

So,

7x = 91

x = 91/7

x = 13

=> Total sandwiches = 12x = 12(13) = 156

A box is to be made from a rectangular piece of corrugated cardboard, where the length is 8 more inches than the width, by cut

Ksenya-84 [330]

The volume of a box like this is found by multiplying the length times the width times the height. We are told that the length is 8 more inches than the width, so the width is w and the length is w + 8. If we cut away 3 square inches from each corner, the height when we fold up those corners is going to be 3. The volume is given as 27, so our formula looks like this: $27=(3)(w)(w+8)$ . When we do that multiplication, we have $27=3w^2+24w$ . We need to solve for w so we can then solve for h. Move the 27 over and set the quadratic equal to 0. $3w^2+24w-27=0$ . We can then factor out a 3 to make the job easier: $3(w^2+8w-9)=0$ . Now we can factor to solve for w. The 2 numbers that add up to 8 and multiply to -9 are 9 and -1. So (w+9) = 0, (w-1) = 0, or 3 = 0. Of course 3 doesn't equal 0, so that's out. w + 9 = 0 so w = -9. w - 1 = 0 so w = 1. There are 2 things in math that can never EVER be negative and those are time and distance/length. So -9 is out. That means that w = 1. But don't forget that there was 6 inches cut off each side, so the width is 1 + 3 + 3 which is 7. The length is w + 8 which means that the length is 7 + 8 or 15. Those are the dimensions of the rectangle before it was cut.
