Assuming one electrician-day is the same as another, the total job is ...
... (18 electricians)×(35 days) = 630 electrician·days
When that work is split among 28 electricians, it can be expected to take ...
... (630 electrician·days)/(28 electricians) = 22.5 days
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.
Answer:
28.25ounces of jam
Step-by-step explanation:
339ounces ÷ 12 cousins= 28.25
Therefore, each cousin will get 28.25ounces of jam
Answer:
y = -1/2x + 5
Step-by-step explanation:
To get the perpendicular line first, take the negative reciprocal of the slope.
2 -> -1/2
So far, the equation is y - -1/2x ± b. (since we are using mx + b)
Since you want the point (4, 3) to cross over the line, we substitute values in.
3 = -1/2(4) + b
3 = -2 + b
b = 5
Your equation that fits the answer is -1/2x + 5.
Your welcome!
