To paint a sunset, you make a shade of orange paint using 55 drops of red paint for every 88 drops of yellow paint. If you use 1

alexandr402 [8]

Since the ratio of red drops to yellow drops is 55:88 and you have 1515 red drops, the yellow drops needed is given as
If 55=1515
88=?
88/55*1515=2424
therefore 2424 drops of yellow will be needed to make a shade of orange

Two lines are intersecting what is the value of x

Dafna11 [192]

Answer:

$x=111$

Step-by-step explanation:

Since these angles are supplementary, they add up to 180°.

Let's make an equation.

$360=(x+23)+(2x+4) \\ \\ 360=x+23+2x+4 \\ \\ 360=3x+27 \\ \\ 3x=333 \\ \\ x = 111$

Homework = 12.5% of 24 hours = 0.125 x 24 = 3 hours

Sam spent <u>3 hours</u> on homework.

Proportion of the time spent on homework = 3/24 = 1/8

Answer: Same spent 1/8 of his day on homework.

Answer:

y = x + 1

Step-by-step explanation:

1) First, find the slope of the line between the two points. Whichever option has the same slope would be the right answer. To find this, use the slope formula $\frac{y_2-y_1}{x_2-x_1}$ . $x_1$ and $y_1$ represent the x and y values of one point, and $x_2$ and $y_2$ represent the x and y values of another point.

So, use the points given to answer the question. Substitute 4 for $x_1$ , 5 for $y_1$ , 8 for $x_2$ , and 9 for $y_2$ then solve:

$\frac{(9)-(5)}{(8)-(4)} \\= \frac{9-5}{8-4} \\= \frac{4}{4} \\= 1$

Therefore, the slope is 1.

2) Any line that is in a "y = a number" format is a horizontal line, and all horizontal lines have a slope of 0 - so the second option can't be the answer.

The rest of the options are in slope-intercept form, or y = mx + b format. Remember that the coefficient of the term with the x is the slope. Knowing this, y = x + 1 would need to be the answer since the coefficient of the term with the x is 1, and we already calculated that the slope is 1.
