Answer: Number 1= 2
Number 2= 55
Step-by-step explanation:
1. 16 divided by 4 is 4, 4-2=2
2. 22 divided by 2 is 11, 15 divided by 3 is 5, 11x5=55
Square Root of 8 to the nearest tenth, means to calculate the square root of 8 where the answer should only have one number after the decimal point.
Here are step-by-step instructions for how to get the square root of 8 to the nearest tenth:
Step 1: Calculate
We calculate the square root of 8 to be:
√8 = 2.82842712474619
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
2.82
Step 3: Round
Round 2.82 so you only have one digit after the decimal point to get the answer:
2.8
To check that the answer is correct, use your calculator to confirm that 2.82 is about 8.
Answer:
25 roses and 40 white carnations
Step-by-step explanation:
To solve this problem, we must recall that the formula
for velocity assuming linear motion:
v = d / t
Where,
v = velocity
d = distance
t = time
For condition 1: bus travelling on a level road
v1 = d1 / t1
<span>(v2 + 20) = (449 – d2) / 4 --->1</span>
For condition 2: bus travelling on a winding road
v2 = d2 / t2
<span>v2 = d2 / 5 --->2</span>
Combining equations 1 and 2:
(d2 / 5) + 20 = (449 – d2) / 4
0.8 d2 + 80 = 449 – d2
1.8 d2 = 369
d2 = 205 miles
Using equation 2, find for v2:
v2 = 205 / 5
v2 = 41 mph
Since v1 = v2 + 20
v1 = 41 + 20
v1 = 61 mph
Therefore
<span>the
average speed on the level road is 61 mph.</span>
