Answer:

               (rs)(4) = 8

Step-by-step explanation:

r(x)=2√x         s(x)=√x

(rs)(x) = r(x) × s(x) = 2√x ×√x = 2x

Answer:

Cost of 1 pound if sliced ham = $4

Step-by-step explanation:

Mrs. Ruiz bought 4 1/4 pounds of sliced ham for $17. At that rate, what is the cost of 1 pound of sliced ham?

Total pounds of ham bought= 4 1/4 pounds

Total cost = $17

what is the cost of 1 pound of sliced ham

Cost of 1 pound if sliced ham = Total cost of 4 1/4 sliced ham / 4 1/4

= $17 ÷ 17/4

= 17 × 4/17

= 4

Note:4 1/4 = 17/4

Cost of 1 pound if sliced ham = $4

Check:

4 1/4 pounds × $4 per pound

= 17/4 × 4

= $17

Answer:

-5x-8.14 is the correct answer

Step-by-step explanation:

First distribute the terms

12x - 1.7 - 17x  -6.7 =

Then add/subtract similar terms

12x - 17x = -5x

-1.7 -6.7 = -8.14

so it's -5x -8.14

:)

Answer: -5x-8.4

Step-by-step explanation:

[tex]\left(12x-1.7\right)-\left(17x+6.7\right)[/tex]

remove the parentheses

[tex]12x-1.7-17x-6.7[/tex]

Simplify

Group like terms

[tex]12x-17x-1.7-6.7[/tex]

Add

[tex]12x-17x=-5x=[/tex]

[tex]-5x-1.7-6.7[/tex]

Subtract

[tex]-1.7-6.7=-8.4[/tex]

= [tex]-5x-8.4[/tex]

Answer: 25 units.

Step-by-step explanation:

Given: B is the midpoint of line segment AC.

[tex]\Rightarrow\ AB=\dfrac{AC}{2}[/tex]

If [tex]AB = 4x + 1[/tex] and [tex]AC = 5x + 20[/tex], then we have

[tex]4x+1=\dfrac{5x+20}{2}[/tex]

Multiply 2 on both sides, we get

[tex]2(4x+1)=5x+20\\\\\Rightarrow\ 8x+2=5x+20\\\\\Rightarrow\ 8x-5x=20-2\\\\\Rightarrow\ 3x=18\\\\\Rightarrow\ x= 6[/tex]

Now, AC = 5(6)+20 =30+20=50 units

Then, BC= [tex]\dfrac{50}{2}=25\text{ units}[/tex]  

Hence, the length of BC is 25 units.

Answer:

When w =8. then...

8^2-4(8)-2.

64-32-2=30.

Answer:

Step-by-step explanation:

Plug in the value of w in the expression and use PEMDAS

w² - 4w - 2 = 8² - 4*8 - 2    {Need to calculate exponents}

                   = 64 - 4*8 - 2  {Now do multiplication}

                   = 64 -  32 - 2

                 =   32 - 2

                 = 30

[tex]\dag\bf\:A(x_1,y_1)=(1,5)[/tex]

[tex]\dag\bf\:B(x_2,y_2)=(3,13)[/tex]

[tex]\bigstar\:\boxed{\bf{AB=\sqrt{(x_2-x_1)^2+(y_2+y_1)^2}}}[/tex]

[tex]:\implies\tt\:AB=\sqrt{(3-1)^2+(13-5)^2}[/tex]

[tex]:\implies\tt\:AB=\sqrt{(2)^2+(8)^2}[/tex]

[tex]:\implies\tt\:AB=\sqrt{4+64}[/tex]

[tex]:\implies\tt\:AB=\sqrt{68}[/tex]

Answer:

3

Step-by-step explanation:

The horizontal component of the force is 25.98 lb and the vertical component is 15 lb.

A vector quantity has both magnitude and direction. It is added using parallelogram law of addition.

The sum of two vector quantities is always a vector quantity.

The sum of two vector quantities can vary from their scalar difference to their scalar addition.

Given that,

The force applied by the man is 30 lb.

The angle the force makes with ground is 30°.

For a vector A making angle x with the horizontal axis the horizontal and vertical component are given as,

The horizontal component is ACos(x)

And, the vertical component is ASin(x)

Thus, the horizontal and vertical component of the force are

Horizontal component = 30Cos(30°)

                                      = 30 × √3 / 2

                                      =  25.98

Vertical component = 30Sin(30°)

                                  = 30 × √3/2

                                  = 15

Hence, the horizontal and vertical components of the force are 25.98 lb and 15 lb respectively.

Step-by-step explanation:

We have to assume that the question is referring to the doubly-shaded length, the one that is 10 bright blue units long.

You can read the overall length of the shaded area as 5/4, from the markings.

For the next part, you need to count the number of units that are shaded bright blue (10) and the number that are shaded blue overall (15). As a fraction of those shaded blue overall, the ones shaded bright blue are 10/15 = 2/3.

So, the length shaded bright blue is 2/3 of the overall length of 5/4. It is represented by the product ...

Answer:

y = 3x -1

Step-by-step explanation:

y = mx +/- b

To find the y-intercept, using the table, we look for when x = 0. In this question, when x=0, y = -1. Therefore the y-intercept is -1.

to find the slope (m), we just plug in an "x" value and "y" value, and solve for "m".

i.e.

2 = 1m - 1

3 = 1m

m = 3 = slope

If you use this with any of the other values you will get the same result.

by using quadratic formula

A number line shows the comparison between numbers, at a regular interval.

The correct number line that compares [tex]\sqrt{24[/tex] and [tex]4.256[/tex] is (c)

The numbers are given as:

[tex]n_1 = \sqrt{24}[/tex]

[tex]n_2 = 4.256[/tex]

So, we have:

[tex]n_1 = \sqrt{24}[/tex]

Take square roots

[tex]n_1 = 4.899[/tex]

4.899 is greater than 4.256 i.e. [tex]n_1 > n_2[/tex]

So, we have:

[tex]\sqrt{24} > 4.256[/tex]

Number lines increases in value towards the right. This means that:

The solution is Option B.

The ratio of thick paintbrushes to thin paintbrushes is 3 : 2

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the equation be represented as A

Now , the value of A is calculated as

Let the number of thin paintbrushes in the kit be = x

The value of x = 4

Let the number of thick paintbrushes in the kit be = y

The value of y = 6

Now , the proportion is given by

The ratio of thick paintbrushes to thin paintbrushes = number of thick paintbrushes in the kit / number of thin paintbrushes in the kit

Substituting the values in the equation , we get

The ratio of thick paintbrushes to thin paintbrushes = 6 / 4

The ratio of thick paintbrushes to thin paintbrushes = 3 / 2

The ratio of thick paintbrushes to thin paintbrushes = 3 : 2

Therefore , the value of A is 3 / 2

Hence , the ratio of the paintbrushes is 3 : 2
