Answer:
1.)21°
2.)51°
3.)73°
4.)50°
Step-by-step explanation:
1.) 90° - 69°
= 21°
2.) 90° - 39°
= 51°
3.) 90° - 17°
= 73°
4.) 90° - 40°
= 50°
I think it’s A sorry if I’m wrong had someone else to help answer it
First we have to find the slope of the given line. We do that by puttiing the equation into slope-interept form. or solving it for y (same thing). 2x + 4y = -6. We move the 2x over by subtraction to get 4y = -2x - 6. Divide both sides by 4 to get the slope-intercept form we are seeking.
. The slope that is perpendicular to that slope of -1/2 is the opposite reciprocal. Therefore, the perpendicular slope is a positive 2/1 or just 2. If this new line goes through the point (2, 5), it goes through the x value of 2 and the y value of 5. We will use those values along with the slope of 2 to solve for b in our slope-intercept equation. That looks like this:
and b = 1. That means our new equation, the one that is perpendicular to the given line, has an equation of y = 2x + 1.
Answer:
(70-55)/4.5=y rounded down to the nearest whole number
Step-by-step explanation:
The first step is to take away the $55 from $70
70-55=15
Simba has $15 to spend on the yoga classes, to find the number of yoga classes she can attend, you divide 15 by the amount a yoga class costs, $4.50
15/4.50=3 1/3
Because she can not have 1/3 of a yoga class, she can attend 3 yoga classes in her budget.
