The capacity of thumb drive disc is 4 gigabytes and the capacity of compact disc is 2 gigabytes.

Let thumb drive = (x)

Let the capacity of 1 compact disk = (y).

Therefore, the appropriate equation will be:

4x + y = 18

4x + 3y = 22

Subtract the equations

2y = 4

y = 4/2

y = 2

The capacity of compact disc is 2 gigabytes.

Since 4x + y = 18

4x + 2 = 18

4x = 18 - 2

4x = 16

x = 16/4

x = 4

The capacity of thumb drive disc is 4 gigabytes.

Answer:

[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]

Step-by-step explanation:

Given the expression

[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^mb^m=\left(ab\right)^m[/tex]

[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}=\left(5\times \:25\right)^{\frac{1}{3}}[/tex]

               [tex]=125^{\frac{1}{3}}[/tex]

[tex]\mathrm{Factor\:the\:number:\:}\:125=5^3[/tex]

               [tex]=\left(5^3\right)^{\frac{1}{3}}[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}[/tex]

               [tex]=\left(5^3\right)^{\frac{1}{3}}=5^{3\times \frac{1}{3}}=5[/tex]

Thus,

[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]

The coordinates of point S is (4, -15)

The given parameters are

T = (0, 5)

Midpoint = (2, -5)

The midpoint of a line is calculated using

Midpoint = 1/2 * (x1 + x2, y1 + y2)

So, we have

(2, -5) = 1/2 * (0 + x, 5 + y)

This gives

(4, -10) = (x, 5 + y)

Solve for x and y

So, we have

x = 4

5 + y = -10

This gives

x = 4

y = -15

Hence, the coordinates of point S is (4, -15)

Step-by-step explanation:

Answer:

[tex]\displaystyle x=\frac{39}{10}[/tex]

The midpoint of a line bisects that line into two congruent line segments - otherwise speaking, they are equivalent to each other.

Due to this, we can set the equations equal and solve for x.

First, set the equations equal to one another.

[tex]17x = 7x + 39[/tex]

Subtract 7x from both sides of the equation to combine like terms.

[tex]17x - 7x = 7x - 7x + 39[/tex]

[tex]10x =39[/tex]

Then, divide both sides of the equation by 10 to isolate the variable.

[tex]\displaystyle \frac{10x}{10} = \frac{39}{10}[/tex]

[tex]\displaystyle x=\frac{39}{10}[/tex]

[tex]\displaystyle \boxed{\bold{x=\frac{39}{10}}}[/tex]

Solution :-

given that,

→ Cost of meal before tax = $ 40

and,

→ Tax = 8.5%

So,

→ Total tax paid = 8.5% of cost of meal = (40 * 8.5)/100 = $ 3.4

now,

→ Tip = 18% of cost of meal = (18 * 40)/100 = $ 7.2

then,

→ Total cost of the meal = Cost of meal before tax + Total tax paid + Tip = 40 + 3.4 + 7.2 = $50.6 ≈ $51 (Ans.)

Shortcut :-

→ Total cost of the meal = Cost of meal * (100% + 8.5% tax + 18% tip) = 40(1 + 0.085 + 0.18) = 40 * 1.265 = $50.6 ≈ $51 (Ans.)

The required relation whose constant of proportionality matches with the constant of proportionality given in the graph.

Given that,
A curve is shown in the graph, it is to be determined that the constant of proportionality of the curve matches one of the curves given in the options.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.

Here,
Constant of proportionality  for the given function,

y/x = 2 / 8 = 0.25

Since the constant of proportionality of the functions mentioned in Option A, C and E matched with the given graph.

0.065*100=6.5

Answer:

$6.25

Step-by-step explanation:

Each football costs the same amount, and each basketball costs the same amount.

Let the cost of:

Footballs = f

Basketballs = b

Hence, we have the following system of equations

At the first store, the coach paid $110 for 5 footballs and 14 basketballs.

5f + 14b = 110

At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.

10f + 6b = 82.50

What was the cost in dollars of each basketball?

5f + 14b = 110..... Equation 1

10f + 6b = 82.50.....Equation 2

We solve using Elimination method.

Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f

50f + 140b = 1100.... Equation 3

50f +30b = 412.5.......Equation 4

Subtract Equation 4 from Equation 3

110b = 687.5

b= 687.5/110

b = $6.25

Therefore, the cost of one basketball in dollars = $6.25
