2r-3.1=1.7 add 3.1
2r=1.7+3.1 divide by 2 to isolate r
2r/2=4.8/2
r=2.4
check
2(2.4)-3.1=1.7
4.8-3.1=1.7
1.7=1.7
4t+3.5=12.5 sub 3.5
4t=12.5-3.5 divide by 4
4t/4=9/4
t=9/4
check
4(9/4)+3.5=12.5
9+3.5=12.5
12.5=12.5
8m-5.5=10.1 add 5.5
8m=10.1+5.5 divide by 8
8m/8=15.6/8
m=1.95
check
8(1.95)-5.5=10.1
15.6-5.5=10.1
10.1=10.1
Answer:
bread bread bread baking day
Answer:
a. 1
b. 2.
Step-by-step explanation:
a) There are a total of 10 numbers so we have:
4 * 10 = 3+5+6+8+9+2+1+0+5+x
40 = 39 + x
x = 1.
b) 5*6 = 28 + x
x = 2.
Answer:
72°
Step-by-step explanation:
Hello There!
Complementary angles have a sum of 90 degrees
So to find the missing angle we subtract the measure of the given angle (18 in this case) from 90
90 - 18 = 72
so your answer will be 72°
<h2>
Average speed in first ten seconds in 10 m/s</h2>
Step-by-step explanation:
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 0 m/s
Acceleration, a = 2 m/s²
Time, t = 10 s
Substituting
s = ut + 0.5 at²
s = 0 x 10 + 0.5 x 2 x 10²
s = 100 m
Distance traveled is 100 m
Time taken is 10 seconds
We have
Distance = Time x Average speed
100 = 10 x Average speed
Average speed = 10 m/s
Average speed in first ten seconds in 10 m/s
