triangle abc and dgf are similar the lengths of two corresponding sides are 1.4 m and 56 cm what is the ratio of the perimeters of these triangles?
Answers
1.4 meters is equal to 140 centimeters. We can find the ratio with just these two side lengths because we know that the shapes are similar, so the other corresponding sides will also have the same ratio.
Then, we can take 140 and divide it by 56 which, simplified, gives us the fraction 5/2. Because of the Fundamental Theorem of Similarity, you keep the fraction the way it is. (If you are finding the ratio of areas or surface areas, you square the fraction, and if you are finding the ratio of the volumes you cube it.)
I hope this helped, if you are confused or this didn’t help, feel free to ask questions!

A. 50 meters
B. 40 meters
C. 25 meters

a farmer has harvested 60% of his crops if he has harvested 72 acres , how many acres does the farmer have in all ?
Answers
Answer: The farmer has 120 acres total.
Step-by-step explanation: To get this answer you have to cross multiply and divide. So make two fraction like things right next to each other with an equal sign in the middle. The first fraction like thing your going to put is going to have 72 on the top and your going to leave the bottom blank. For the second fraction like thing you are going to put 60 on top and 100 on the bottom. Next you will multiply 72 by 100, and with that answer you will divide it by 100. Then the answer to that is what goes into that first fractions bottom slot. That answer in the bottom slot is your number of acres total.

120

Answers
4/5 - /7 =
4/5 - 2/7
5 * 7 = 35
7 * 4 = 28
5 * 2 = 10
28/35 - 10/35 = 18/35
Answer:
The missing numerator is 2.
Step-by-step explanation:
when you plug in 2 as the missing numerator and simplify you get 18/35.
[tex]\frac{4}{5}[/tex] -[tex]\frac{2}{7}[/tex]=[tex]\frac{18}{35}[/tex]
the subtraction turns into 28/35 minus 10/35 which equals to 18/35
