What is the surface area of a cereal box with a height of 10 inches, a width of 4 ½ inches, and a length of 7 inches?
Answer:
Surface area of a box = 293 inches ²
Step-by-step explanation:
Surface area of a box = 2(lw + lh + hw)
Where,
l = length = 7 inches
w =width = 4 1/2 inches
h = height = 10 inches
Surface area of a box = 2(lw + lh + hw)
= 2(7*4.5 + 7*10 + 10*4.5)
= 2(31.5 + 70 + 45)
= 2(146.5)
= 293 inches ²
Surface area of a box = 293 inches ²

Which function shown below has the greater rate of change? Explain. (Be sure to include the
rate of change for each in your explanation).
Answer:
Function 1 has a greater rate of change.
Step-by-step explanation:
Function 1 has a rate of change of 3 because 3x is the slope of the line.
Function 2 has a rate of change of 1.5, because when you use rise/run, you get a slope of 3/2.
Function 3 has a rate of change of 2. You use the formula (y2 - y1) / (x2 - x1) to find the slope. I used (0,0) and (1,2). When you plug in 2 for y2, 1 for x2, and 0 for y1 and 0 for x1, you get (2-0) / (1-0) which is 2/1. That equals a slope of 2.

Nathan buys a blender with a listed price of $65. Nathan uses a coupon that provides 20% off. What is the total final price Nathan pays?
Answer:
$52
Step-by-step explanation:
Given data
Price of blender= $65
Coupon = 20%
Let us find the amount of the coupon
=20/100*65
=0.2*65
=$13
Hence the amount of the coupon is $13
The total price Nathan pays is
=65-13
=$52

If u=0, make t the subject of the following equation: s=ut+1/2at^2 Please look at image.
Answer:
[tex]t=\sqrt{\dfrac{2s}{a}}[/tex]
Step-by-step explanation:
The given equation is :
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
s is displacement
u is the initial velocity
a is acceleration
t is time
If u = 0, the above equation become,
[tex]s=\dfrac{1}{2}at^2\\\\t^2=\dfrac{2s}{a}\\\\t=\sqrt{\dfrac{2s}{a}}[/tex]
Hence, the value of t is equal to [tex]\sqrt{\dfrac{2s}{a}}[/tex].

Rona was driving on an asphalt road that had a 35 mile per hour speed limit posted. A lrr r deer jumped out from the side of the road causing Rona to slam on her brakes. Her tires left three skid marks of lengths 70 ft., 72ft., and71ft. The road had a drag factor of .78. Her brakes were operating at 95% efficiency. The police gave Rona a ticket for speeding. Rona insisted that she was driving under the speed limit. Who was correct (the police or Rona)
Answer:
The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."
Step-by-step explanation:
Finding the average skid distance:
[tex]Average=\frac{70+71+72}{3}=\frac{213}{3}=71[/tex]
Calculating the skid:

Jack have 8 jellies and his brother have 17 jellies.
What is fraction?A number expressed as a quotient, in which a numerator is divided by a denominator.
Total number of jellies= 25.
The jellies is to be divide between jack and his brother.
let us consider jack has 'x' jellies
Then, his brother have '2x+1'
So, x+ 2x+1=25
3x+1=25
3x=24
x=8
So, jack have 8 jellies and his brother have 2*8+1= 17 jellies.

2000 restaurants will grow about 3% every year, what is the equation that represents it. Y = restaurants and t = years
Answer:
Y= PV*(1 + g)^t
Step-by-step explanation:
Giving the following information:
Number of Restaurants (PV)= 2,000
Growth rate (g)= 3%
To calculate the number of restaurants after t years, we need to use the following formula:
Y= PV*(1 + g)^t
For example, for 10 years:
Y= 2,000*(1.03^10)
