Your car can drive 300 miles on a tank of 15 gallons. How far can it drive on 40
gallons?

Answers

Answer: 800

20x40=800

The car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

Your car can drive 300 miles on a tank of 15 gallons

300 miles → 15 gallons

Let x be the number of miles or distance a car travel in 40 gallons

x → 40 gallons

300/x = 15/40

x = (300×40)/15

x = 800 miles

Thus, the car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

Large bags hold 14 apples. When a fourth grade class went to apple picking, they filled 9 large bags. How many apples did they pick?

Answers

14x9=90+36=126. They picked 126 apples.

Answer:

They picked 126 apples

Step-by-step explanation:

Because 1 large bag holds 14 apples, and 9 large bags were filled, you would need to multiply 14 by 9. 14 multiplied by 9 equals 126

Find the midpoint of the segment joining X(5,6) and Y(9,2).

Answers

Answer:

(7,4)

Step-by-step explanation:

The midpoint formula is:

[tex]M=(\frac{x_1+x_1}{2},\frac{y_1+y_2}{2})[/tex]

Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:

[tex]M=(\frac{5+9}{2},\frac{6+2}{2})[/tex]

Add:

[tex]M=(\frac{14}{2},\frac{8}{2})[/tex]

Divide by 2:

[tex]M=(7,4)[/tex]

So, our midpoint is (7,4).

And we're done!

Find the general solution of the following equation: y'(t) = 3y -5

Answers

Answer:

The general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5

Step-by-step explanation:

Since the differential equation is given as y'(t) = 3y -5

The differential equation is re-written as

dy/dt = 3y - 5

separating the variables, we have

dy/(3y - 5) = dt

dy/(3y - 5) = dt

integrating both sides, we have

∫dy/(3y - 5) = ∫dt

∫3dy/[3(3y - 5)] = ∫dt

(1/3)∫3dy/(3y - 5) = ∫dt

(1/3)㏑(3y - 5) = t + C

㏑(3y - 5) = 3t + 3C

taking exponents of both sides, we have

exp[㏑(3y - 5)] = exp(3t + 3C)

3y - 5 = [tex]e^{3t}e^{3C}[/tex]        

3y - 5 = [tex]Ae^{3t}[/tex]                [tex]A = e^{3C}[/tex]

3y = [tex]Ae^{3t}[/tex] + 5    

dividing through by 3, we have

y = [tex]\frac{A}{3}e^{3t}[/tex] + 5

So, the general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5

A: if i’m not correct, it looks like ur looking for slope. if so, c

explanation: slope is as follows: rise/run.
this slope is negative, because it is going down [think abt it like this, if you place a skier on this line, will he ski up or down?].

to find slope you can use the equation y2-y1/ x2-x1 = slope (m)

select 2 pairs of points. i chose (-4,-1) and ( 3,-4). because the point form is (x,y) my x1 = -4, y1 = -1 and x2 = 3, y2= -4.

let’s plug them into the equation above: -4 - (-1) / 3- (-4) = m

solve: -4 + 1/ 3+4 = -3/7

m= -3/7 or C

2.) distribute the 1 and -1 to (x+4) and (3x+6) --> 1+x+4 = -3x-6+1

3.) Put common terms on the same side (so x's together and the numbers together) so you will add 3 to the right side and add 3x to the left side

Under which conditions does the commutative property apply to compositions of f(x) and g(x)? A- When they are inverse functions B- when they are equal for at least one value of x C- when they are equal for all values of x D- when they are not inverse functions

Answers

Answer:

  A- When they are inverse functions

  C- when they are equal for all values of x

Step-by-step explanation:

The order of function application in a composition can be reversed if ...

the functions are inverses of each otherthe functions are identical (equal for all values of x)

_____

In the first case, the composition gives an output equal to its input for the functions in either order.

In the second case, you cannot tell the functions apart, since they produce the same output for the same input. Hence, you can't tell if they are reordered or not.

11(15g-13)=-6 help please

Answers

Answer:

g = 0.83

Step-by-step explanation:

11(15g-13) =-6

165g - 143 = -6

165g = 137

165      165

g = 0.83

The solution of the given equation 11(15g-13) = -6 is g = 0.83

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given equation is,

11(15g-13) = -6

To solve the above equation following steps are taken,

Divide both the side of the equation by 11

11(15g-13)/11 = -6/11

Solving them we get,

15g - 13 = -6/11

Adding 13 both the sides,

15g - 13 + 13 = -6/11 + 13

So we obtain,
15g  = -6/11 + 13

Solving the numbers right hand side,we get

15g = 137/11

Dividing both the sides by 15 we get,

g = 137/165

or, g = 0.83

Hence,The solution of the given equation 11(15g-13) = -6 is g = 0.83
