Answer:
The correct answer would be (8,2.40).
Step-by-step explanation:
Option one(-3, -0.9) and two (-2.5, -0.75) Would not be a viable solution because the value of number of days can not be negative and in option one and two, value of days -3 and -2.5 is negative.
Option three(4.5, 1.35) can not be correct because library charges fee for a full day so the number for days would be a whole number. Library would not charge for 4.5 days, they would either charge of 4 days or 5 days because 4.5 is not an whole number.
Option four(8, 2.40) is the correct answer because it satisfies our equation;
Y= 0.30 * X
2.40= 0.30 * 8
2.40 = 2.40
hope this helps :)
The weight (y) will always be positive, the number of balls (x) too. So without the bucket, the function would be:
y = 1.6x
Now we have to add the weight of the bucket which is 2lb, or the same 32oz.
So the function results:
y = 1.6x + 32 (oz.)
If there is 1 ball, the weight is 1.6+32 = 33.6 oz. If there are no balls, the weight is 0 + 32 = 32 oz.
It is very important that all terms in the equation are in the same units, oz. in this case. Otherwise, if you do not translate lb. to oz. the resulting equation will be wrong.
If you need the equation expressed in lb., you only need to multiply the equation by 1lb/16oz:
y = = 0.1x + 2 (lb.)
1) Surface Area = 2(lw + lh + wh)
2(4*5+4*9+5*9) =202in^2
Surface Area=202in^2
Lateral Area= Perimeter of base * height
5+5=10 <--width+width
4+4=8 <---length + length
10+8=18 <--total perimeter
18 * 9=162in^2 <--multiplied the height +perimeter of base
Lateral Area=162in^2
2) Same concept as the previous one
Surface Area = 2(lw + lh + wh)
2(4*2+4*5+5*2) =76in^2
Surface Area= 76in^2
Lateral Area
Lateral Area= Perimeter of base * height
4+4=8
2+2=4
8+4=12
12 x 5=60
Lateral Area= 60in^2
Answer:
k+15
Step-by-step explanation:
The word "increased" indicates that there will be addition and the word "product" indicates there will be multiplication. Since it's asking for the product of 5 and 3, we can solve by multiplying those two numbers to get 15. Our variable k will then add 15. So, the final answer we get is: k+15
