Answer:
$2.55
Step-by-step explanation:
If you Multiply $85 by 0.03 you get your answer because you have to turn the 3% into a decimal which you have to move the decimal two places to the left.
8. complementary angles = 90°
3x+3+10x-4 = 90
13x-1 = 90
13x = 91
so x = 91/13= 7
then K = 3(7)+3 = 24°
so L = 10(7)-4 = 70-4 = 66°
9. P is three less than twice of Q
so P = 2Q-3
supplementary angles = 180°
P+Q = 180
(2Q-3)+Q = 180
3Q-3 = 180
3Q = 183
so Q = 183/3 = 61°
then P= 2(61)-3 = 122-3 = 119°
10. B is two more than three times of C so B= 3C+2
complementary angles = 90°
B+C= 90
(3C+2)+C=90
4C+2=90
4C= 88
so C= 22°
then B = 3(22)+2= 66+2 = 68°
5x - 2y = 10
Isolating y:
-2y = 10 - 5x
y = (10 - 5x)/(-2)
y = 10/(-2) + (-5x)/(-2)
y = -5 + 5/2x
This equation has the slope-intercept form with a slope of 5/2 and a y-intercept of -5
Answer:
Take another look at 4 and 6.
The others are correct.
Step-by-step explanation:
The sides of a 30°-60°-90° right triangle have the ratio 1 : √3 : 2. All your triangles (should) have these ratios.
