Answer:

Ricardo ran a total of 10.75 miles on Monday.

[tex]n =1.95[/tex]

Step-by-step explanation:

Given

[tex]10.75 = 5.5n[/tex]

Required

Which situation represents the equation and solve for n

The options show the relationship between distance, time and speed.

This is calculated as:

[tex]Distance = Speed * Time[/tex]

By comparison:

[tex]Distance = 10.75[/tex]

[tex]Speed = 5.5[/tex]

[tex]Time = n[/tex]

So, we can say that:

He ran 10.75 miles (option D)

Solving for n:

Make n the subject in [tex]10.75 = 5.5n[/tex]

[tex]\frac{10.75}{5.5} = n[/tex]

[tex]n = \frac{10.75}{5.5}[/tex]

[tex]n =1.95[/tex]

Answer:

-25

Step-by-step explanation:

Given the equation 25 + x =

Subtract 25 from both sides

25 + x - 25 = 0 - 25

x = 0 - 25

x = -25

Hence the blank box will be -25

Answer:

B. 13 small bags and 12 large bags

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of small bags.

y is the number of large bags.

The Tuesday morning delivery consists of 25 bags

This means that [tex]x + y = 25[/tex], that is [tex]y = 25 - x[/tex]

Bunyan Farm sells 3 pound and 5 pound bags of onions. Total of 99 pounds.

This means that [tex]3x + 5y = 99[/tex]

Since [tex]y = 25 - x[/tex]

[tex]3x + 5(25 - x) = 99[/tex]

[tex]3x + 125 - 5x = 99[/tex]

[tex]-2x = -26[/tex]

[tex]2x = 26[/tex]

[tex]x = \frac{26}{2}[/tex]

[tex]x = 13[/tex]

[tex]y = 25 - x = 25 - 13 = 12[/tex]

So 13 small bags and 12 large bags.

Answer:

  55°

Step-by-step explanation:

A couple of auxiliary lines can be helpful.

We see that 45° is an exterior angle to the bottom triangle, which has remote interior angles that must total 45°. This means the interior angle at bottom left must be 45° -15° = 30°.

The upper right interior angle is alternate to that, so is the same measure. The exterior angle x to the upper triangle is then the sum of the remote interior angles:

  x = 25° +30°

  x = 55°

Answer:

Step-by-step explanation:

The function doesnt have an inverse. In order for a function to actually have an inverse, it has to pass the horizontal line test. The function above has repeating y-values because of the x^2.

With all this said, you can still find the inverse of the function as long as you restrict the domain (x-values) for the function. So, you cant consider the negative x-values.

First, replace f(x) with y and then switch the x and y variables

[tex]x=2y^2-4[/tex]

Then solve for y by adding 4 to both sides, dividing by 2, and finally taking the square root.

[tex]x+4=2y^2[/tex]

[tex]\frac{x+4}{2} =y^2[/tex]

[tex]\sqrt{\frac{x+4}{2} }=y[/tex]

Where is question

Step-by-step explanation:

Answer:

Approximately [tex]4.70 \times 10^{2}\; \rm J[/tex], assuming that [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].

Step-by-step explanation:

When the force [tex]F[/tex] is constant, moving by [tex]\Delta x[/tex] in the direction of the force would do a work of [tex]F \cdot \Delta x[/tex].

However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.

Let [tex]F(x)[/tex] denote the force required to lift the chain when the height above the ground is [tex]x[/tex] meters. At that moment, exactly [tex](x / 10)[/tex] of the chain would be above the ground. The mass of that much of the chain would be [tex](x / 10)\![/tex] the mass of the whole chain.

[tex]\begin{aligned}F(x) &= m(x) \cdot g \\ &= 60 \cdot \frac{x}{10} \cdot g = 6\, g\, x\end{aligned}[/tex].

Integrate with respect to [tex]x[/tex]:

[tex]\begin{aligned}\int \limits_{0}^{4} F(x) \cdot {\rm d} x &= \int \limits_{0}^{4} 6\, g\, x \cdot {\rm d} x \\ &= \left[(3\, g)\, x^{2}\right]_{x=0}^{x=4}\\ &= 48\, g \approx 4.7 \times 10^{2} \end{aligned}[/tex].

In other words, it would take approximately [tex]4.7 \times 10^{2}\; \rm J[/tex] of energy to raise one end of the chain to that height of [tex]4\; \rm m[/tex].

Answer:

option 2

Step-by-step explanation:

x is going away from 7 in a positive direction which means greater than. the fact that it is just greater than not equal to means that there is a black circle instead of a filled in one because it excludes that number.

Answer:

Option 2

Step-by-step explanation:

If the inequality is "x > 7" it means that if it was to be represented on a number line, all values that "c" could possibly take would be located to the right (on the number line) of 7. Now there only two options that follow this statement, those options are options 2 and 4. But there is another thing we must understand. x must be larger than 7 (it can not be equal to 7), therefor option 2 is right since it follows the second statement  while option 4 would represent inequality "x ≥ 7".      

Answer:

Step-by-step explanation:

-20 and -40

quotient means divide one another

-20 / -40

= 20/40

= 2/4

= 0.5

I made these into tiny tiny steps, enjoy.

The translation of  the simplified algebraic expression for "the quotient of -20 and -40" is  [tex]\dfrac{1}{2}[/tex].

A collection of constants, variables or numbers connected using one or more arithmetic operator is called an algebraic expression .

Example = 4y, 3x+4.

The quotient of -20 and -40 can be written as:

[tex]\dfrac{-20}{-40}[/tex]

The expression can be simplified in the lowest form as;

[tex]\dfrac{-20}{-40}[/tex]    =     [tex]\dfrac{1}{2}[/tex]

So, the simplified algebraic expression for "the quotient of -20 and -40" is  [tex]\dfrac{1}{2}[/tex].

Answer:

B and C

Step-by-step explanation:

Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.

A minimum point occurs where all the nearby values are higher than that of the point in question.

A maximum point occurs where all the nearby points are lower than the point in question.

By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)

By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.

Answer:

P=(Probablility of a guest sitting in a section that gets a hat) =number of ways it can happen/total number of outcomes. =5/40= 1/8

Step-by-step explanation:

The probability of a guest sitting in a winning section is 1/8.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, The seats are divided into 40 sections and hats are to be given in only 5 sections.

Here, N(S) = 40 and N(H) = 5.

Therefore, We know, P(H) = N(H)/N(S).

P(H) = 5/40.

P(H) = 1/8.
