Question:
Marco plotted the following points on the number line.
Point A: 0.3 Point B: 3/4 Point C: 11/4 Point D: 0.7
Which point did he plot incorrectly?
Answer:
Point D
Step-by-step explanation:
Given
Required
The incorrectly plotted point
Number plotted on a number line increases from left to right. This implies that:
Substitute the values for the given points
Express as fractions
Up till 2.75, the order of the numbers is correct.
However, 0.7 is less than 0.75 and 2.75
So, 0.7 is not placed correctly.
<em>This implies that point D is not correctly placed</em>
3x-7=14
Hoped this helped!
Answer:$9
Step-by-step explanation:Here's what we know:
2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)
What we need to do is isolate s
Simplify:
48 + 3s = 75
subtract 48 from both sides:
48 + 3s - 48 = 75 - 48
3s = 27
Divide by 3:
3s / 3 = 27 / 3
s = 9
Shirts are $9 each.
You will want to divide the shape up into different parts to solve this. For example, first I would take the top rectangle (24x5=120) and add the answer of that to the rectangle in the middle section (120+(11x10)=230). Then, I would add the very last rectangle at the very bottom of the total we have so far (230+(7x3)=251). Lastly, I would take the semi-circle and find its area ((3.14x2)^2)/2=19.7192). Then, add all of the totals together and get your answer of
= 250.7192km^2
*note, only put the number of decimals needed.
Thanks :)
