Answer:3 lines could be used
Step-by-step explanation:
You need 2 points to draw a line. The order doesn't really matter. Line AB is the same as line BA. The problem is to select 2 points out of 3 to draw different lines. If we do the same to the others, we get the following pairs of points to draw lines.
AB , AC
BA , BC
CA , CB
which is only 3 lines
Answer:
63 divided by 7 is 9
56 divided by 7 is 8
Step-by-step explanation:
I don't really know how to explain it, because it's kind of complicated to do it how I answered it. I will try, but what you do is write out the equation using the little line division thing with the divisor and the dividend. First for 63 divided by 7, how many times can 7 go into 6? 0, so put a 0 on top of the 6. Then, minus 6 by 0, which is 6. Then, drop down the 3 in the ones place to where the difference of the subtraction problem is, which of 6. Then, we try to find a product that is 63 or close to 63 in a multiplication problem, and one of those factors has to be 7. 7 x 9 = 63, so put a 9 on top of the 3 at the beginning and minus 63 - 63, which is 0, meaning it has no remainder. Very hard to explain digitally, look up a video for help.
18.4 since the hundredths place is the number right after the decimal
Answer:
B. 200 mm²
Step-by-step explanation:
The area of a rectangle part of the figure is found using length x width, which in this case is 25 x 2 = 50 mm²
The area of a triangle is found using . Since the values given are the legs that make up the right angle, your base and height are 15 mm and 20 mm. This means the area is , which is 150 mm².
The area of the figure as is whole is 50 + 150, which is 200 mm².
Answer:
Option D.
Step-by-step explanation:
Let
x ----> the smaller number
y ----> the larger number
we know that
The larger number is twice the value of 4 more than the smaller number
----> equation A
Their difference is 11
----> equation B
substitute equation A in equation B
Solve for x
Find the value of y
therefore
The numbers are 3 and 14
