Answer:
a) 0.4
b) 0.07
c) 3
e) 1.23
f) 0.19
I) 3.3 = 3.300
j) 5.64
Step-by-step explanation:
0.4 = 4/10
0.07 = 7/100
0.603 = 603/1000
0.64 = 0.64000000
Answer:
1. t > -6 (Graph A)
2. x ≤ −80 (Graph B)
3. b < 13 (Graph C)
Step-by-step explanation:
<u>1. t < 5t + 24</u>
t − 5t < 5t + 24 − 5t
−4t < 24
−4t/−4 < 24/−4
t > −6
<u>2. 5x−9≤4.1x−81</u>
5x - 9 - 4.1x ≤ 4.1x - 81 - 4.1x
0/9x - 9 ≤ -81
0.9x - 9 +9 ≤ -81 + 9
0.9x ≤ -72
0.9/0.9 ≤ -72/-72
x ≤ -80
<u>3. 4b+4(1-b)>b-9</u>
so so and on
24 students ===> 100% of the third test &
150% of the second test is 150% of 24 students:
So the 150% in the second test correspond to 150% x 24 = 36
Answer:
Step-by-step explanation:
The measure of each angle in an equilateral triangle is 60°. Divide that value by the coefficient of the variable in the equation:
3x = 60° ⇒ x = 20°
4y = 60° ⇒ y = 15°
5z = 60° ⇒ z = 12°
