Answer:
each trip travelled 3106 km
Step-by-step explanation:
The computation of the each ship travelled is shown below:
= Distance travelled ÷ number of ships
= 6212 km ÷ 2 ships
= 3106 km
Hence, each trip travelled 3106 km
We simply applied the above formula
Answer:
A) a/b = d/c
Step-by-step explanation:
The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally.
In this case, line TU is parallel to side QR. So, the ratios a:b and d:c are equal. In other words, a/b = d/c
A) 31%
B) 31%
For the first problem, we know that 25 out of 80 tokens are black. To find the percentage all we have to do is divide 25 by 80, which equal 0.31. To convert this to percentage form, you move the decimal two places to the right, giving you 31%.
And for the second problem you do the same thing. Divide 5 by 16, giving you 0.31. Convert that into percentage, also giving you the percent of 31%.

First, the best advice I can give you is to go to sleep. You pretty much know what you know, and being well-rested will help you think clearly, recall details, and avoid careless mistakes.
1)
![=(5 \times 10^3)+(2 \times 10^2)=(50 \times 10^2)+(2 \times 10^2)\\=10^2(50+2)=52 \times 100 = 5200 = 5.2 \times 10^3](https://tex.z-dn.net/?f=%3D%285%20%5Ctimes%2010%5E3%29%2B%282%20%5Ctimes%2010%5E2%29%3D%2850%20%5Ctimes%2010%5E2%29%2B%282%20%5Ctimes%2010%5E2%29%5C%5C%3D10%5E2%2850%2B2%29%3D52%20%5Ctimes%20100%20%3D%205200%20%3D%205.2%20%5Ctimes%2010%5E3)

3) Yes, dilating with a scale factor that is less than 1 (and greater than 0) corresponds to a decrease.
4) Yes, dilating with a scale factor greater than 1 corresponds to an increase.
5) To find the slope of a scatter plot, you need to make a line of best fit, that is, the line that passes through as many points as possible and has about as many points above it as below it. Then, find two of those points that the line passes through and calculate the slope between those points. For two points
![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
and
![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
, the slope is
![m= \dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%20%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
.
This is an estimate. To find a better approximation, you can use the least-square method, but I think that probably involves higher-level math that you don't need. If you think you do need to solve it this way, just comment here and I'll explain it. Note that you can also calculate it using Microsoft Excel or a regression plot on a graphing calculator.
