Answer:
9:00pm
Step-by-step explanation:
20 + 20 + 20 +20 + 20 + 20 + 20 + 20 +20 = 180
45 + 45 + 45 + 45 = 180
Bus A would've taken 9 routes and Bus B would've taken 4, to reach the bus depot together
180 mins - hours = 3 hours
6 + 3 = 9
Answer:
15 seeds
Step-by-step explanation:
Set up a ratio that represents the problem:
Sown Seeds : Seeds That Grow
100 : 75
Find the unit rate:
The unit rate is when one of the numbers in a ratio is 1. For this problem, let's make the number of sown seeds equal to one.
To do this, divide by 100 on both sides of the ratio.
100 : 75
/100 /100
1 : .75
This means that if Tim sows 1 seed, .75 will grow.
Answer the question:
We need to find the number of seeds that would grow if Tim planted 20 seeds. Therefore, multiply by 20 on both sides of the ratio.
1 : .75
x20 x20
20 : 15
Therefore, if Tim plants 20 seeds, we would expect 15 to grow.
Answer:
An algebraic rule is a mathematical expression that relates two variables and is written in the form of an equation. There are many constant algebraic rules, such as area = length x width. You can also create your own rule when given a set of variables.
Step-by-step explanation:
Answer:
<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
We know that
V = πr²h
400 = 22/7 × r² × 8
400 × 7 = 22 × 7r²
2800 = 154r²
2800/154 = r²
18 ≈ r²
4.2 = r
