Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
Answer:
- (b) x- intercept is -1/3; y-intercept is -3/2
Step-by-step explanation:
<u>Given function:</u>
<u>x- intercept is:</u>
- y = 0 ⇒ -9x = 3 ⇒ x = -1/3
<u>y-intercept is:</u>
- x = 0 ⇒ -2y = 3 ⇒ y = -3/2
Correct answer choice is (b)
Office income = 12 months * (2600 pounds)/month = 31,200 pounds
Gym income = 39 weekends * (80 pounds)/weekend = 3,120 pounds
Total income = 31,200 + 3,120 = 34,320
3,120/34,320 = 39/429 = 3/
Step-by-step explanation:
Firstly we need to ratio the fertilizer to plant food:

Lets add these two values together:

So now we know one of each, we can divide the above value into 42 to find out the amount:
42 ÷
= 8
So this means that 8 portions of each can be used. This can calculate the full ratio by multiplying each ratio by 8:
=
12 : 30
