The computer will be worth $200.

Step-by-step explanation:

A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.

Answer: The value of the computer at time 0 is $800

The value of the computer at time 1 is $600

The value of the computer at time 2 is $450

The value of the computer at time 3 is $337.50

The value of the computer at time t is (n - 1) x 3/4

Answer:

9[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplify the radicals

[tex]\sqrt{20}[/tex]

= [tex]\sqrt{4(5)}[/tex]

= [tex]\sqrt{4}[/tex] × [tex]\sqrt{5}[/tex]

= 2[tex]\sqrt{5}[/tex]

[tex]\sqrt{45}[/tex]

= [tex]\sqrt{9(5)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex]

= 3[tex]\sqrt{5}[/tex]

Then

3[tex]\sqrt{20}[/tex] + [tex]\sqrt{45}[/tex]

= 3(2[tex]\sqrt{5}[/tex] ) + 3[tex]\sqrt{5}[/tex]

= 6[tex]\sqrt{5}[/tex] + 3[tex]\sqrt{5}[/tex]

= 9[tex]\sqrt{5}[/tex]

Answer:

The answer is 131 people

Step-by-step explanation:

I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.

Hopefully that helped lol

Step-by-step explanation:

step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)

step 2. 15x + 15 = 180 (like terms)

step 3. 15x = 165 (subtract 15 from each side)

step 4. x = 11. (divide both sides by 15)

Answer:

No

Step-by-step explanation:

Because after u substitute the 15 for the x u get 38>42 which is incorrect

Answer:

3( y - 2) + 2y =9

Step-by-step explanation:

It equals 3.

Answer:

y=3

Step-by-step explanation:

3(y-2)+2y=9

3y-6+2y=9

Isolate the variable y by transposing

3y+2y=6+9

y=3

Answer:kk

Step-by-step explanation:

Answer:

A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity

Step-by-step explanation:

Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.

...

Example 2.

Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day

Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

Answer:

x=10

Step-by-step explanation:

Let's solve your equation step-by-step.

(x−3)(x−5)=35

Step 1: Simplify both sides of the equation.

x2−8x+15=35

Step 2: Subtract 35 from both sides.

x2−8x+15−35=35−35

x2−8x−20=0

Step 3: Factor left side of equation.

(x+2)(x−10)=0

Step 4: Set factors equal to 0.

x+2=0 or x−10=0

x=−2 or x=10

Answer:

5

Step-by-step explanation:

2x - 3 = 7

this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7

then you can just solve for x

2x=10

x=5

Step-by-step explanation:

Answer:

282%

Step-by-step explanation:

2 and 41/50 is also 82/100 so 282%

The mixed number A = 2 41/50 as a percentage is P = 282 %

Given data ,

Let the percentage value be represented as P

Now , the mixed number is given as A

where the value of A = 2 41/50

On simplifying the number , we get

A = 2 82/100

where the conversion of a fraction to a percent, we divide the numerator by the denominator and multiply by 100.

(141/50) x 100 = 282/1

On simplifying the equation , we get

P = 282%

Therefore, 2 41/50 is equal to 282%

Hence , the percentage value is A = 282 %

Answer:

75 m

Step-by-step explanation:

1m 60 cm = 160 cm

160cm-85cm= 75 cm

~ 75 cm of tape is left in the roll.

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Consider all positive integers that are multiples of 10 and are less than or equal to 200.

Let the number of the positive integer that are multiples of 10 be x. Then the equation will be

10x ≤ 200

Then the value of the x will be

x ≤ 20

The set of numbers is given below.

Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}

The set which is divisible by 15 will be

Set = 6 {30, 6,0 90, 120, 150, 180}

Then the fraction of those integers are multiples of 15 will be

⇒ 6 / 20

⇒ 3/10

The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

Answer:

[tex]4\sqrt{2}[/tex]

Step-by-step explanation:

distance formula:[tex]\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}[/tex]

set square to be centered on the origin and find the distance between 2 of the connected points

[tex]\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}[/tex]

= [tex]\sqrt{\left(1\right)^{2}+\left(1\right)^{2}}[/tex]

= [tex]\sqrt{2}[/tex]

multiply by 4 as it is a square and all of its sides are equal

[tex]4\sqrt{2}[/tex]

insert units

[tex]4\sqrt{2}\ \ meters[/tex]

The perimeter of the square is √32.

Given to us

As we can see in the figure AB is the diagonal of the square and diameter of the circle. therefore,

AB = Diagonal of the square = Diameter of circle = 2 x Radius = 2 meter

We know the diagonal of a square is equal to the product of √2 and the side of the square.

[tex]Diagonal = side \times {\sqrt2}[/tex]

Substitute the value,

[tex]2 = side \times {\sqrt2}\\\\side = \dfrac{2}{\sqrt2}\\\\side ={\sqrt2}[/tex]

The perimeter of the square is four times the side of the square.

[tex]Perimeter = 4\times (side)[/tex]

Substitute the value,

[tex]Perimeter = 4\times (\sqrt2)\\\\Perimeter = 4\sqrt2 = \sqrt{2\times 16} = \sqrt{32}[/tex]

Hence, the perimeter of the square is √32.

Answer:

d. AAS

Step-by-step explanation:

These triangles can be proven congruent through AAS, or angle, angle, side. This means that two angles and one nonincluded side are congruent. Two sides are marked as congruent through a tick mark, and one angle pair is marked by one arc on each angle. We also know that the middle angles, that are connected, are congruent because they are vertical angles. Therefore, they are congruent, which can be proven by AAS.
