Answer:

the answer is below :)

Step-by-step explanation:

BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  ($120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x to find where the gigabytes are the same.

100 + 10x = 120 + 5x

Subtract 100 from both sides:  10x = 20 + 5x

Subtract 5x from both sides:  5x = 20.

Divide both sides by 5:  x = 4.  4 gigabytes is the answer.

a brainliest would be appreciated :)

The total amount you will pay for phone service is 4 gigabytes.

An equation is an expression that shows the relationship between two or more numbers and variables.

BigBytes will be 100 +10x = y

Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  

We have $120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x;

100 + 10x = 120 + 5x

Now Subtract 100 from both sides:  

10x = 20 + 5x

Then Subtract 5x from both sides:

5x = 20.

Now Divide both sides by 5:  

x = 4.  

Hence, the total amount you will pay for phone service is 4 gigabytes.

Answer:

8,000^0.0625=5

Step-by-step explanation:

Lol I was doing my homework rn and I wasn't 100% sure of my answer so I looked it up on brainly. So an exponential equation should look like this e^a=b so with the three values $8,000 , 6.25% , and 5 years I kind of just mixed around the numbers a bit in the exponential equation till one worked. So yeah...

Answer:

f(t)=8000e^(0.0625)(5)

Step-by-step explanation:

exponential growth function is f(t)=Pe^(rt)

where P is starting value, or price

e is the e on you calculator

r is rate of increase, in this case 6.25/100 is 0.0625, which is the rate

t is the time given

Answer:

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

There are various types of sampling used by researchers and these are;

1. Random sampling.

2. Systematic sampling.

3. Stratified sampling.

4. Cluster sampling.

5. Opportunity or convenience sampling.

Opportunity sampling is also known as convenience and it can be defined as a sampling technique which typically involves the process of selecting participants from a population of interest (target group) to take part in a research study.

This ultimately implies that, an opportunity sampling is a non-probability sampling in which a researcher select participants based on their availability for the study.

For example, John a psychologist standing on the street requesting that passersby join in his research study.

Answer:

Step-by-step explanation:

volume = πr²h = π·3²h = 63π

h = 7 cm

The height of the given cylinder is 7 cm. Therefore, option D is the correct answer.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, the volume of a cylinder is 63π cm³ and the radius is 3 cm.

We know that, the formula to find the volume of a cylinder is πr²h.

Now, πr²h=63π

π×3²×h=63π

h= 7 cm

Therefore, option D is the correct answer.

Answer:

2x + 5y = 6

Step-by-step explanation:

The equation of a line parallel to 2x + 5y = 30 has exactly the same form as does 2x + 5y = 30, but the constant is different.  Starting with 2x + 5y = 30, replace the constant (30) with C, x with 3 and y with 0:

2(3) + 0 = C, so C = 6

Then the desired equation is 2x + 5y = 6

logan = x + 2

-------

5 yrs back

lindsey = x - 5

logan = x + 2 - 5 = x - 3

x = 38/ 2 = 19

Answer:

6.75 m

Step-by-step explanation:

Time = 45 mins

Speed = 0.15 m/min

Distance = Speed * time

Distance = 0.15 m/min * 45 mins = 6.75 m

Answer:

6.75m

Step-by-step explanation:

We know that she jogged for 45 minutes and was going around 0.15m/min so we can multiply her distance per minute (0.15m/min), by the number of minutes(45min).

If we use Long Multiplication also known as Standard Algorithm it should look like this:

We have to multiply 0.15 x 100 or move the decimal two spaces

Once you get your answer (675) just move the decimal 2 spaces forward or divide by 100. You should get 6.75, and now just add your label (m)

Answer:

The density of the metal C is 2 g/cm³

Step-by-step explanation:

The parameters of the two metals are;

The density of the Metal A = 2.4 g/cm³

The density of the Metal B = 1.8 g/cm³

The ratio in which their masses are combined to make the metal C= 2:3

The mass of the metal C, m = 60 grams

Let, 'x', represent the mass of the metal A in the 60 grams of the metal C and let 'y' represent the mass of the metal B in the 60 grams of the metal C

Let the ratio of the metals A and B in the metal C = x:y = 2:3

Therefore;

The mass of the metal A in the metal C, x = (2/(3 + 2)) × 60 g = 24 g

The volume of the metal A in the metal C, V₁ = (24 g)/(2.4 g/cm³) = 10 cm³

The mass of the metal B in the metal C, y = (3/(3 + 2)) × 60 g = 36 g

The volume of the metal B in the metal C, V₂ = (36 g)/(1.8 g/cm³) = 20 cm³

The volume of the metal C, V = V₁ + V₂ = 10 cm³ + 20 cm³ = 30 cm³

The density of the metal C = ρ = m/V

ρ = (60 g)/(30 cm³) = 2 g/cm³

The density of the metal C, ρ = 2 g/cm³

Answer:

if 100 came by in 2 hours 50 would come by in one hour

Step-by-step explanation:

split it it's by 2

If 100 came by in 2 hours then 50 would come by in one hour.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

We have been given 100 cars pass by in 2 hours​

We need to find the unit rate.

Total car = 100

Time = 2 hours

Unit rate = 100/2

Unit rate = 50

Therefore, the unit rate of 50 car in one hour.

Answer:

3 pieces

Step-by-step explanation:

Given: Figure

To find: Number of 8.5 in. ×  11 in. pieces used to cover the floors  of a room and a hallway in  her dollhouse

Solution:

In the given figure, AC = 22 in.

AB + BC = 22 in.

AB + EF = 22 (As BC = EF being opposite sides of rectangle)

AB + 10 = 22

AB = 22 - 10 = 12 in.

Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches

(area of rectangle = length × breadth )

CE = CD + DE = AH + GF (As CD = AH and DE = GF)

CE = 5 + 15 = 20 inches

Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches

(BC = EF = 10 in.)

Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches

Area of pieces of felt = 8.5 × 11

So,

Number of pieces required = Total area of the figure / Area of pieces of felt  =   3 pieces
