Answer:
5cm by 1.95cm
Step-by-step explanation:
Let the length of the rectangle be x
Let the width be y
Perimeter of a rectangle = 2x + 2y
If the initial perimeter of a rectangle is about 13.9 cm, then;
13.9 = 2x + 2y ..... 1
If when the width is double the perimeter is 17.8cm, then;
17.8 = 2x + 4y ..... 2
Subtract 1 from 2;
13.9 - 17.8 = 2y - 4y
- 3.9 = -2y
y = 3.9/2
y = 1.95 cm
Substitute y = 1.95 into 1 to get x;
From 1;
13.9 = 2x + 2y
13.9 = 2x + 2(1.95)
13.9 = 2x + 3.9
2x = 13.9-3.9
2x = 10
x = 5 cm
Hence the dimension of the smaller triangle is 5cm by 1.95cm
Answer:
The answer is c
Step-by-step explanation:
You have to do everything backwards,
-9 divide it by 3 to get -3, then add seven to that answer
Any angle that would be less than 80 degrees would be known to be called an "Acute Angle". Therefore, your correct answer would then be known to be called an Acute Angle.
I hope this helps you!
1 MILLIliter, namely one thousandth of a liter, meaning there are 1000 mLs in one liter.
the spoon holds 5 mL, how many are there in 1 liter? namely how many times is 5 in 1000? simply 1000 ÷ 5 = 200.
The answer would be 7 i think:)
