What is the volume of this rectangular prism?

Answer:

The amount of time it takes to ride 26 miles is 2.89 hours.

Step-by-step explanation:

Given : You ride your bike at 9 miles per hour.

To find : How long it will take you to ride 26 miles ?

Solution :

The equation given is [tex]9\times t=26[/tex]

Using distance formula,

[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]

According to formula t represent the time taken to cover the distance.

Your speed in miles per hour is 9 miles per hour.

The number of miles you've traveled so far is 26 miles.

Solving the equation,

[tex]9\times t=26[/tex]

[tex]t=\frac{26}{9}[/tex]

[tex]t=2.89[/tex] hours

The amount of time it takes to ride 26 miles is 2.89 hours.

Answer:

Our final answer is option B that is [tex]10x^2-42x+8[/tex]

Step-by-step explanation:

As we have to multiply the binomial.

Here is the work.

Using distributive law of multiplication.

Where [tex]a(b+c)=ab+ac[/tex]

⇒[tex](5x-1)(2x-8)[/tex]

  [tex]5x(2x-8)-1(2x-8)[/tex]

  [tex]10x^2-40x-2x+8[/tex]...     [tex](-1\times -8 =8)[/tex]

  As [tex]-40x[/tex] and [tex]-2x[/tex] are in negative so we will add these      

  numbers keeping the negative sign as it is.      

  [tex]10x^2-42x+8[/tex]

So the correct choice is option B that is [tex]10x^2-42x+8[/tex]

Answer:

± 11[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

x² + 11² = 22², that is

x² + 121 = 484 ( subtract 121 from both sides )

x² = 363 ( take the square root of both sides )

x = ± [tex]\sqrt{363}[/tex] = ± [tex]\sqrt{121(3)}[/tex] = ± 11[tex]\sqrt{3}[/tex]

m=(y2-y1)/(x2-x1)

m=(-13-(-3))/(6-2)

m=(-13+3)/4

m=-10/4

simplify,

m=-5/2

[tex]14\ \frac{miles}{gallon}[/tex]

Step-by-step explanation:

we know that

To find out the unit rate (number of miles per gallon of gasoline) divide the total miles driven by the total gallons of gasoline used

so

Step-by-step explanation:

6 - x = -12

subtract 6 from each side

6 - 6 - x = -12 - 6

-x = -18

divide each side by -1

-x / -1 = -18 / -1

x = 18

Answer:

The answer is D.) 18

Step-by-step explanation:

Subtract 6 from both sides. Divide both sides by −1. The answer is 18.

Answer:

(b) y=-3/4x-8

Step-by-step explanation:

The graph that will be perpendicular to the graph 4x - 3y = -12

If this equation is represented in form of the straight line equation y = mx + b

it will change to 3y = 4x + 12

therefore y = (4/3)x + (12/3)

y = (4/3)x + 4

which implies that m = 4/3 while b = 4

However for the line that will be perpendicular to the graph, its slope m1 must be negative inverse of the slope of the initial graph

This is because m x m1 = -1

therefore m1 = -1/m

this implies that the correct answer must have a slope of -1/(4/3) = -3/4

The correct answer can then be analysed by expressing all options with y = mx + b

(a) In form of y = m1x + b, 4x+3y=12 becomes y = -4/3x + 4 (m1 = -4/3: wrong)

(b) In form of y = m1x + b, y=-3/4x-8 has m1 = -3/4 (correct)

(c) In form of y = m1x + b, y=3/4x+1 has m1 = 3/4 (wrong)

(d) In form of y = m1x + b, 3x-4y=1 becomes y = 3/4x - 1/4 (m1 = 3/4: wrong)

Answer:

X-Intercept: (1.2,0)

Y-Intercept (0,.75)

Step-by-step explanation:

If you want fraction form then the

X-Intercept: (6/5,0)

Y-Intercept (0,3/4)

To find the x intercepts, you have to plug y=0 into the equation. After you plug in y=0, you get the equation 5x-9=-3 and once you solve that, you find that the x intercept = 1.2

Likewise, to find the y intercepts, you would plug x=0 into the equation. Once you do that, you get the equation -9=-8y-3 and when you solve for y you get an intercept of 3/4

For this case we must solve the following system of equations:

[tex]3x-3y = -3\\2x-y = -5[/tex]

To solve we follow the steps below:

We multiply the second equation by -3:

[tex]-6x + 3y = 15[/tex]

Thus, we have the equivalent system:

[tex]3x-3y = -3\\-6x + 3y = 15[/tex]

We add the equations:

[tex]3x-6x-3y + 3y = -3 + 15\\-3x = -3 + 15\\-3x = 12\\x = \frac {12} {- 3}\\x = -4[/tex]

We look for the value of the variable "y":

[tex]2 (-4) -y = -5\\-8-y = -5\\-y = -5 + 8\\-y = 3\\y = -3[/tex]

Thus, the solution of the system is given by:

[tex](x, y): (- 4, -3)[/tex]

Answer:

[tex](x, y): (- 4, -3)[/tex]

Answer:

Yes, because 4 + 4 = 8 so it is the same as 7 × 8.

Answer:

Yes.

Step-by-step explanation:

This is because if using PEMDAS, you will see that (4+4) = 8.

That would mean that 7x(4+4) =7x8, and that Paulo is correct.

Answer:

The required number is 8.

Step-by-step explanation:

Given : If [tex]\frac{1}{2}[/tex] is subtracted from four times the reciprocal of a number, the result is 0.

To Find : The number ?

Solution :

Let the number be x.

The reciprocal of number is [tex]\frac{1}{x}[/tex]

[tex]\frac{1}{2}[/tex] is subtracted from four times the reciprocal of a number, the result is 0.

The equation will become,

[tex]4\times \frac{1}{x} - \frac{1}{2}=0[/tex]

Solving the equation we get,

[tex]\frac{4}{x} -\frac{1}{2}=0[/tex]

[tex]\frac{4}{x} = \frac{1}{2}[/tex]

[tex]x= 4\times 2[/tex]

[tex]x=8[/tex]

Therefore, the required number is 8.

Let's try all of the possible answer choices.

Any result that is even, we cross off the list. Otherwise we have our answer.

If c = -8, then c-8 = -8-8 = -16 which is even. Cross this off the list

If c = 0, then c-8 = 0-8 = -8, which is even. Cross this off the list.

If c = -5, then c-8 = -5-8 = -13, which is odd. We have our answer

If c = 10, then c-8 = 10-8 = 2, which is even. Cross this off the list

Answer:

log 5 5

= 1.

Step-by-step explanation:

Use the logarithm law  loga b - loga c = loga b/c:

log5 125 – log5 25

= log5 125 / 25

= log5 5.

= 1.

The expression log5 125 - log5 25 simplifies to 1.

To combine the logarithms log5 125 and log5 25 as one logarithm and simplify, we can use the properties of logarithms. Specifically, we'll use the property that states logb(x) - logb(y) = logb(x/y). Applying this property, we have:

log5 125 - log5 25 = log5 (125/25)

We simplify the fraction 125/25 to get 5. So, we have:

log5 (125/25) = log5 5

The logarithm of a number to the base of itself is always 1, so:

log5 5 = 1

Therefore, the expression log5 125 - log5 25 simplifies to 1.

[tex](-xy^{4} b^{2} )^{4}[/tex] can be written as  x⁴y¹⁶b⁸.

Procedures must be made simpler in order to attain uniformity in efforts, expenses, and time. Variety and variation that is unnecessary, damaging, and unproductive are eliminated.

Given an equation  [tex](-xy^{4} b^{2} )^{4}[/tex]  in this, we need to find a monomial in standard form which can be optimized after putting the power back at every variable. hence,

[tex](-xy^{4} b^{2} )^{4}[/tex]  =  (-x)⁴(y⁴)⁴ (b²)⁴

=   x⁴y¹⁶b⁸

Therefore,  a monomial in the standard form  [tex](-xy^{4} b^{2} )^{4}[/tex] is   x⁴y¹⁶b⁸.

Using a red line, we find that the answer is between 115 and 125, closer 125 than 115.

So, if you look all choices, there are two possibilities, C and D. However, $115 million can't be the right answer because our graphic approximation is closer to 125.

Therefore, the right answer is D) $120 million.
