Answer:

7 1/3 gallons

Step-by-step explanation:

If the bucket is half full and still has half to go, you double the current contents of the bucket. 3 4/6 times 2 is equal to 7 2/6 gallons which simplifies to 7 1/3 gallons.

I don't fully understand your question though, if the question is asking how much MORE water is needed to fill the bucket, it's 3 2/3 gallons. If it's asking how much water in TOTAL it would take to fill the bucket completely, it's 7 1/3 gallons.

Answer:

The distance would be 6.7 or 3✓5

Step-by-step explanation:

Im sure there's a faster way to find this, but I'm in 8th grade sooo yeah.

First things first we can use the equation

d=✓(X2-X1)*2+(Y2-Y1)*2

X2= 8

X1= 5

Y2= 13

Y1= 7

From here, you plug in the values and do as followed. You subtract the values to get the answer. For example 8-5 would get us (3)*2.

From here you square the 3 to get 9. You also do the same to the right side of the equation.

Now you have d=✓(3)*2 + (6)*2

From here you square it and you get d=✓9+36

Now we have: d✓45

Now we square the 45 to get 6.7082..., but we round the answer to get 6.7!

Hope this helps! If you have any questions please feel free to ask, as I understand the struggle of math! :)

31

The expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

An expression that has a value of 31

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

A) 3√25 + 7-5

= 3(5) + 7 - 5

= 15 + 7 - 5

= 17

B) (3√25) +7-5

= (3x5) +7-5

= 15 +7-5

= 17

C) 3√25+ (7-5)

= 3x5 +2

= 17

D) 3(√25 + 7) - 5

= 3(5+7) - 5

= 36 - 5

= 31

Thus, the expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

Answer:

6x^3 + 24x^2

Step-by-step explanation:

We need to find (f * g)(x)

If we distribute the "x" here, we should get f(x) * g(x), which is what we have to solve for

f(x) * g(x) = 6x(x^2 + 4x)

= 6x^3 + 6x(4x)

= 6x^3 + 24x^2

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,4) and (4,-6)

The distance between them is

[tex]d = \sqrt{ ({3 - 4})^{2} + ({4 + 6})^{2} } \\ = \sqrt{ ({ - 1})^{2} + {10}^{2} } \\ = \sqrt{1 + 100 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{101} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

Step-by-step explanation:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{5-5}{-17-(-9)}=\frac{0}{-8} =0[/tex]

slope=0

Given:

JK is formed by J(-12, 3) and K(8,-5).

Line r is the perpendicular bisector of JK.

To find:

The equation of line r is slope intercept form.

Solution:

Line r is the perpendicular bisector of JK. So, it passes through the midpoint of J and K.

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-12+8}{2},\dfrac{3+(-5)}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{-2}{2}\right)[/tex]

[tex]Midpoint=\left(-2,-1\right)[/tex]

Slope of JK is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-5-3}{8-(-12)}[/tex]

[tex]m=\dfrac{-8}{20}[/tex]

[tex]m=\dfrac{-2}{5}[/tex]

Product of slopes of two perpendicular lines is -1.

[tex]m_1\times m_2=-1[/tex]

[tex]-\dfrac{2}{5}\times m_2=-1[/tex]

[tex]m_2=\dfrac{5}{2}[/tex]

The slope of perpendicular line r is [tex]\dfrac{5}{2}[/tex] and it passes through (-2,-1). So, the equation of perpendicular line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(-1)=\dfrac{5}{2}(x-(-2))[/tex]

[tex]y+1=\dfrac{5}{2}(x+2)[/tex]

[tex]y+1=\dfrac{5}{2}x+5[/tex]

[tex]y=\dfrac{5}{2}x+5-1[/tex]

[tex]y=\dfrac{5}{2}x+4[/tex]

Therefore, the equation of line r is [tex]y=\dfrac{5}{2}x+4[/tex].

The required equation of line "r" in slope-intercept form is y = 5/2x + 15

First, we need to find the equation of a line in slope-intercept form as

y = mx + b

m is the slope of the line

b is the y-intercept

Given the coordinate points  J(-12, 3) and K(8,-5)

Get the slope of the line

Slope  = -5-3/8+12

Slope = -8/20

Slope - -2/5

Slope of the line "r" perpendicular is 5/2

Get the y-intercept of line r

Substitute (8, -5) and m = 5/2 into y = mx + b

-5 = -5/2(8) + b

-5 = -20 + b

b = 15

Hence the required equation of line "r" in slope-intercept form is y = 5/2x + 15

Answer:

18=2x+7, The internship pays $5.50 an hour.

Step-by-step explanation:

The box on the far left is the amount the student is paid at their job, which is $18 an hour in this case. Solve 18-7 to get 11, then divide 11 by 2 to get the pay for the internship. To check your work, plug 5.50 into the equation.

18=2(5.50)+7

18=11+7

18=18

Answer:

The equation would be:

18 = 2x + 7

The internship pays $5.5 an hour

Step-by-step explanation:

18 - 7 = 2x

(Since we moved the 7 to the other side, in order to combine like terms)

11 = 2x

(Divide both sides by 2)

5.5 = x

(x = 5.5)

x would be the pay the internship pays an hour.
