Equilateral = all sides are same
side length = 8 3/4 ÷ 3
= 35/4 ÷ 3
= 35/4 × 1/3
= 35/12
1. 1/12 2. 7/15 3. 1/12 4. 11/18
Answer:
91.
Step-by-step explanation:
The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.
2*3*5 = 30 but 31 is not a multiple of 7.
2*2*3*5 = 60 but 61 is not divisible by 7.
2*3*3*5 = 90 and 91 is divisible by 7.
3/8 of the mixture is white; 5/8 is black. Then for 2 gallons of mixture,
.. (3/8)*2 gal = 3/4 gal
of white paint are needed, and
.. (5/8)*2 gal = 5/4 gal
of black paint are needed.
Rounding up to the nearest 1/2 gallon,
.. 1 gallon of white and 1 1/2 gallons of black must be purchased, for a total of 2 1/2 gallons of paint.
Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given:
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate separately and separately and add them. So we have .
Now for the second question: . we would get
Next, . This could be written as: . Hence the answers.
