How many raisins are left in a jar of 37 raisins after you have eaten some? The equation _______ best models this situation. A. R= 37+N B. R=37/N. C. R= N/37. D. R=37-N

The value of the expression when simplified is equal to √5. The correct option is D.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given radical expression can be simplified as shown below,

5√20 - 3√45

Write the under root values in the factored form,

= 5√(4×5) - 3√(9×5)

Simply the function that can be simplified,

= 5(√4 × √5) - 3(√9 × √5)

= 5(2√5) - 3(3√5)

= 10√5 - 9√5

Take √5 as the common term from the two of the given terms,

= (10 - 9) √5

= 1 √5

= √5

Hence, the value of the expression when simplified is equal to √5.

Answers:

x = 16

MB = 31

==================================================

Work Shown:

M is the midpoint of AB

This means AM is half as long as AB and AM = MB

Put another way, AB is twice as long as AM

AB = 2*AM

3x+14 = 2*(2x-1)

3x+14 = 4x-2

14+2 = 4x-3x

16 = x

x = 16

AM = MB

MB = AM

MB = 2x-1

MB = 2*16-1

MB = 32-1

MB = 31

Step-by-step explanation:

a) you just add to get the perimiter 2(900) + 2(400) to get 1790

b) 1000 meters makes a kilometer so we divide by 1000 and get 1.79 for the kilometers

Answer: For the first part, her total savings would be $88, and for the second part, (let's pretend s = the total savings) the equation would be s = 40 + w x 6.

Step-by-step explanation: As for the first part, we would need to multiply her money per week times the amount of weeks she works. We can do this by simply multiplying the amount she makes (6) by the amount of weeks she works (8), resulting in 48, but we still have to add that number to the amount she already has, or 40, making $88 in total, as for the second part, this does a great job of explaining the reasoning behind that as well.

I took the test

Step-by-step explanation: Linear pair postulate

m<abc + m<cbd =180°

subtraction property of equality

m<abc -90°

All expression and phrase are filled below.

Here,

We have to filled all expression and phrase.

What is right angled triangle?

A right-angled triangle is a triangle, which has one of its interior angles equal to 90 degree.

Now,

Given that;

⇒ m∠CBD = 90 degree  ….(i)    

We have to prove triangle ABC is right angled triangle.

We can see that the line extends down and perpendicular to the line segment BC at point B.

We can also see that ∠ABC and ∠CBD are supplementary angle.

Hence, We prove as;

         Statement                                                Reason

1) m∠CBD = 90 degree                                        ( Given )

2) ∠ABC and ∠CBD are supplementary.  ( Because ABD is a line and  

                                                                ∠ABC and ∠CBD are linear

                                                                pair)                                                

3). ∠ABC+∠CBD = 180 degree                ( Definition of supplementary)

4) ∠ABC+ 90 = 180 degree                      (  m∠CBD = 90 degree )

5) ∠ABC + 90 - 90 = 180° - 90°            ( subtraction property of equality)

∠ABC = 180° – 90°    (from (i))

∠ABC = 90 degree

6) ∠ABC is a right angle.                     ( Definition of right angle)

7) Δ ABC is a right triangle.                  ( Definition of right triangle)

Therefore, according to definition of right angled triangle,

The triangle ABC is a right angled triangle.

Answer:

sample answer:   If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4

Step-by-step explanation:

The situation is a representation of the linear function.

Given that,

One dollar is divided into four quarters.

The total number of dollars is a function of the number of quarters.

Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value

As a result, the slope should be 1/4.

y = 1/4x should be the linear function.

Hence, As a result, we can conclude that the situation is a linear function.

It is given that the double number line shows the amount of clay Jamal uses to make different numbers of identical bowls.

We have to solve the subparts of the question to get the values.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.

As per the question ;

The clay needed per bowl = [tex]\frac{2}{3}[/tex] pounds

a)

The equation for clay (c) to make b number of bowls will be ;

Step-by-step explanation:

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]

[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]

[tex]\sqrt{144 + 25 }[/tex]

[tex]\sqrt{169}[/tex]

[tex]13[/tex]

Answer:

[tex]\boxed {d = 13}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following onto the formula:

[tex](x_{1}, y_{1}) = (8, -7)[/tex]

[tex](x_{2}, y_{2}) = (-4, -2)[/tex]

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]

[tex]d = \sqrt{144 + 25}[/tex]

[tex]d = \sqrt{169}[/tex]

[tex]\boxed {d = 13}[/tex]

Therefore, the distance is [tex]13[/tex].
