Sand Hill Crane Elementary is
collecting food to donate. Their goal
is 2 tons of food so far they have
collected 2,798 pounds of food.
How many more pounds of food do
they need to collect?
The pounds of food that Sand Hill Crane Elementary needs to collect more in order to reach their goal is 1202 pounds.
How many more pounds needs to be collected?The first step is to convert tons to pounds.
1 ton = 2000 pounds
2 tons x 2000 = 4000 pounds.
The second step is to subtract the pounds of food collected so far from the goal.
4000 - 2798 = 1202 pounds.

A container manufacturer plans to make rectangular boxes whose bottom and top measure 4x by 3x. The container must contain 48in.3 The top and the bottom will cost $1.80 per square inch, while the four sides will cost $3.70 per square inch.
What should the height of the container be so as to minimize cost? Round your answer to the nearest hundredth.
The height of the container that will be able to minimize the cost will be 3.08cm.
How to calculate the height?The volume of the box will be:
= (3x)(4x)h
= 12x²h
From the information given, we are told that the container must contain 48in³. Therefore,
48 = 12x²h
h = 4/x²
The function cost will be:
= 3.50(2)(12x²) + 4.40(14x)h
= 84x² + 61.6x(4/x²)
= 84x² + 246.4/x
We'll use the first derivative. This will be:
dC/dx = 168x - 246.4/x²
x = 1.14.
Therefore, the height will be:
h = 4/x² = 4/1.14² = 3.08cm
In conclusion, the height is 3.08cm.

Given the function F(x) = 2x2 - 6, find the value F(-1).
Answer:
-4Step-by-step explanation:
Given
F(x) = 2x² - 6We are asked to find F(-1).
This can be done by substituting -1 in place of x in the function.
F(-1) = 2(-1)² - 6F(-1) = 2(1) - 6F(-1) = 2 - 6F(-1) = -418. a gamer played four games in 6 hours. she played each game for the same amount of time. how much time did she play each game on
a.2/3 hours
b. 1 hour
c. 1 1/2 hour
d. 2 hours
Answer:
c. 1 1/2 hours
Step-by-step explanation:
6 hours / 4 games = 1 1/2 hours per game
Another way to think of it:
1 hour = 60 minutes
6 hours = 6 hours x 60 minutes per hour = 360 minutes
360 minutes / 4 games = 90 minutes per game
90 minutes per game / 60 minutes per hour = 1.5 hours
1.5 hours is the same as 1 1/2 hours
So, the answer is c. 1 1/2 hours

Marko is playing the video game Fort Attack. The purpose of the game is to shoot invading bandits that are trying to breach the fort's circular wall, and Marko must provide the angle at which the cannon should turn in order to shoot the attacking bandits. The bandit is attacking as pictured in the figure below:
The unit circle is shown. There is an angle 30 degrees counterclockwise from the positive y axis. An image of a bandit is shown at the point of intersection between the angle and unit circle.
What is the angle of fire in standard position on the unit circle in both degrees and radians?
120°; pi over 6 radians
120°; 2 pi over 3 radians
30°; pi over 3 radians
30°; 2 pi over 3 radians
The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
How to calculate the angle?
It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.
In this case, the value of the angle will be:
= 12π/18
= (12 × 180) / 18
= 12 × 10
= 120°
Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

surface area, in square inches, of the right rectangular prism shown. Is Muna
correct? Explain.
The surface area of a right rectangular prism is the amount of space on it.
Muna's claim is incorrect
How to determine the surface area?
The surface area of a right rectangular prism is calculated as:
A = 2 * (lw + lh + wh)
So, we have:
A = 2 * (8 * 16 + 8 * 12 + 16 * 12)

What is the equation?
Answer:
[tex]\displaystyle 5x + 6y = 72\:or\:y = -\frac{5}{6}x + 12[/tex]
Step-by-step explanation:
Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1⅕ becomes −⅚, and we move forward with plugging the information into the Slope-Intercept formula:
[tex]\displaystyle -8 = -\frac{5}{6}[24] + b \hookrightarrow -8 = -20 + b; 12 = b \\ \\ \boxed{y = -\frac{5}{6}x + 12}[/tex]
To write this in Linear Standard Form, perfourm he following:
y = −⅚x + 12
+ ⅚x + ⅚x
___________
⅚x + y = 12 [We cannot leave the equation this way, so multiply the equation by the denominatour to eradicate the fraction.]

maths j2 a road is 300km long is drawn to a scale of 1cm represents 50km . what is it's length on drawing?
Answer: 6cm.
Step-by-step explanation:
Strategy 1 (in-head thinking)
300 divided by 50 would be 6, multiply 6 by 1 and get 6cm.
Strategy 2 (proportions)
First, set up a proportion.
We know that 1cm = 50km, so we put them on a fraction (whichever is denominator/numerator doesn’t affect the process)
However, we don’t know how much cm equals 300km, so we turn that into a variable, in this case x.
1cm x cm
——— ———
50km 300km
To solve a proportion, go diagonal to where the variables have already been filled in. You can’t so 50km and x cm, as you don’t know x. You can do 300km however. To start, multiply 1 and 300, to which you get 300. Then, multiply 300 by the 50km and you’ll get x. That’ll equal to 6.
So in conclusion, your answer is 6.
