Step-by-step explanation:
Skylar's speed was ...
(65 ft)/(5 s) = 13 ft/s
Rodrigo's speed was ...
(108 ft)/(8 s) = 13.5 ft/s
Rodrigo traveled farther by (13.5 -13) = 0.5 ft per second.
Answer:390
Step-by-step explanation:
130% of a=507
130/100 x a=507
13/10 x a=507
13a/10=507
Cross multiplying we get
13a=507x10
13a=5070
Divide both sides by 13
13a ➗ 13=5070 ➗ 13
a=390
Answer:
50,000
Step-by-step explanation:
20% can be rewritten as 0.2 times 250000: 0.2*250000 = 50,000
Answer: C. -11x^4+x^3+7x^2
Step-by-step explanation:
Combine like terms like -7x^4 and -4x^4, 5x^2+2x^2= 7x^2
Answer:
Step-by-step explanation:
2.
AE=2BD
4x+14=2(4x+5)
4x+14=8x+10
8x-4x=14-10
4x=4
x=1
5.2
AB+ED=2FC
AB+36=2×20
AB=40-36=4
next.
m∠J+m∠N=180
6x+5+9x+20=180
15x=155
3x=31
x=\frac{31}{3}
∠N=9x+20=31×3+20=93+20=113
∠M+∠N=180
∠M+113=180
∠M=180-113=67°
