Answer:
True
Step-by-step explanation:
In this question, we are expected to evaluate the validity of a particular proposition.
To evaluate this validity, what we do is that we check if the calculations as projected on the question are correct.
Let’s proceed!
Number of dogs to cat ratio = 4:5
Number of animals is 270;
Number of dogs will be 4/9 * 270 = 120
Number of cats will be 5/9 * 270 = 150
Now let’s check if the number of dogs is 4/5 that of cats.
Obviously 4/5 * 150 = 120
This makes true, the statement
Answer:
Step-by-step explanation:
Given equation:
Expand the left side:
Let all terms on the left side have the same denominator of 7:
Join the terms on the left side:
Let all the terms on the right side have the same denominator of 3:
Join the terms on the right side:
Cross multiply:
Expand:
Add 12x to both sides:
Add 252 to both sides:
Divide both sides by 40:
Answer:
1- 3/20
2- 12
Step-by-step explanation:
Given that Lenox ironed 1/4 of the shirts over the weekend, and she plans to split the remainder of the work equally over the next 5 evenings, to determine what fraction of the shirts will Lenox iron each day after school, and, if lenox has 40 shirts, how many shirts will she need to go on Thursday and Friday, the following calculations must be performed:
1---
(3/4) / 5 = X
0.15 = X
15/100 = X
3/20 = X
So each day she will iron 3/20 of her shirts.
2---
40 x (3/20) x 2 = X
6 x 2 = X
12 = X
So on Thursday and Friday she will iron 12 shirts.
Answer:
h(n) = h(n - 1) - 13
Step-by-step explanation:
Given
h(n) = - 13n, then
h(1) = - 13 × 1 = - 13 and
h(n) = h(n - 1) - 13 with h(1) = - 13
