Problem 1
<h3>Answer: 2/5</h3>
--------------------------
Explanation:
There are 4 green blocks out of 4+6 = 10 total. We divide the number of green over the number total to get the answer. Reduce the fraction as much as possible. The fraction 4/10 reduces to 2/5 (we divide both parts by 2).
====================================================
Problem 2
<h3>Answer: 1/6</h3>
--------------------------
Explanation:
The probability the spinner lands on red is 2/6 = 1/3. This is because there are 2 spaces that are red out of 6 total. It helps to reduce as much as possible.
The probability the coin lands on heads is 1/2 because there's 1 side labeled heads out of 2 total.
Multiply the fractions: 1/3 * 1/2 = 1/6
This works because both events are independent.
So 3150÷7=450 and then multiply 450×3= 1350. So 1350 people who jog regularly
Answer:
4%
Step-by-step explanation:
To solve this problem we can use a modified version of the simple interest formula which is shown below:
<em>I = interest amount
</em>
<em>P = principal amount
</em>
<em>t = time (years)
</em>
<em />
Lets plug in the values:
The last step is to convert 0.04 into a percent:
0.04(100) = 4
The interest rate is 4%.
All you have to do is find the area of the flower bed if it was a circle using (pi)r^2 and then divide by 2,
d=2r 3=2r, r=1.5
the area of the circular flower bed is (pi)(1.5)^2
Semicircular : [ (pi)(1.5)^2 ] / 2
This, rounded to the nearest decimal place is 3.5m^2
Answer:
X = 8
Step-by-step explanation:
80 - 3(x) = 56
-3(x) = -24
X = 8
