2 answers:

2 quarts is half of a gallon, 4 quarts is one gallon. So the question is pay 3 dollars for half a gallon, or pay 3 dollars for one gallon? Which would you do? they both are the same price, but one is half as much.

Therefor, 1 gallon of milk is a better deal.

1 gallon for $3 is the better deal because you're getting twice as much for the same price

There were 42 apples in each crate. 12 such crates of apples were delivered to a factory. 4 apples were rotten and had to be thr

algol [13]

Answer:

50 boxes

Step-by-step explanation:

first we can find how many apples there are

42*12=504

then subtract 4 of the rotten apples

504-4=500

then find how many boxes there can be

500/10=50

A ball dropped from the top of a building can be modeled by the function f(t)=-16^2+36, where t represents time in seconds

Viefleur [7K]

Answer:

The ball is dropped from a height of 36 feet

The bee and the ball will collide after approximately 1.3 seconds

The bee and the ball will collide at approximately 8 feet above the ground

The ball hits the ground after 1.5 seconds

Step-by-step explanation:

The complete question is

A ball dropped from the top of the building can be modeled by the function f(t)=-16t^2 + 36 , where t represents time in seconds after the ball was dropped. A bee's flight can be modeled by the function, g(t)=3t+4, where t represents time in seconds after the bee starts the flight.

The graph represents the situation.

select all that apply

1) The bee launches into flight from the ground.

2) The ball is dropped from a height of 36 feet.

3) The bee and the ball will collide after approximately 1.3 seconds.

4) The bee and the ball will collide after approximately 8 seconds.

5) The bee and the ball will collide at approximately 8 feet above the ground.

6) The bee and the ball will not collide.

7) The ball hits the ground after 1.5 seconds

see the attached figure to better understand the problem

Verify all the options

case 1) The bee launches into flight from the ground.

The statement is false

Because

we have

$g(t)=3t+4$

For t=0

$g(t)=3(0)+4=4\ ft$

That means ----> The bee launches into flight from a height 4 feet above the ground

case 2) The ball is dropped from a height of 36 feet

The statement is true

Because

For t=0

$f(t)=-16(0)^2+36=36\ ft$

case 3) The bee and the ball will collide after approximately 1.3 seconds

The statement is true

Because

Equate f(t) and g(t)

$-16t^2+36=3t+4$

$-16t^2-3t+32=0$

solve the quadratic equation by graphing

The solution is t=1.324 sec

see the attached figure N 2

case 4) The bee and the ball will collide after approximately 8 seconds

The statement is false

Because, the bee and the ball will collide after approximately 1.3 seconds (see case 3)

case 5) The bee and the ball will collide at approximately 8 feet above the ground

The statement is true

Because

For t=1.324 sec

substitute the value of t in f(t) or g(t)

$g(t)=3(1.324)+4=7.97\ ft$

case 6) The bee and the ball will not collide

The statement is false

see case 3) and case 5)

case 7) The ball hits the ground after 1.5 seconds

The statement is true

Because

we know that

The ball hit the ground when the value of f(t) is equal to zero

For f(t)=0

$-16t^2+36=0$

$t^2=\frac{36}{16}$

$t=\frac{6}{4}=1.5\ sec$

If g(x) = 2(x − 4), find the value of x if g(x) = 20. 32 12

nlexa [21]

Answer:

The value of x is $14$

Step-by-step explanation:

we have

$g(x)=2(x-4)$ ------> equation A

In this problem we have

$g(x)=20$

Substitute the value of g(x) in the equation A and solve for x

$20=2(x-4)$

Divide by $2$ both sides

$20/2=2(x-4)/2$

$10=(x-4)$

Adds $4$ both sides

$10+4=(x-4)+4$

$x=14$
