Step-by-step explanation:

Given that [tex]\sqrt{7569}=87[/tex] we're in search for the value of  [tex]\sqrt{7569} +\sqrt{75.69}[/tex].

Simplify the square roots.

[tex]\sqrt{7569} +\sqrt{75.69}[/tex]

I am thinking of 3 consecutive numbers less than 100.The first number has 5 as one of its factors, the second number has 1 as its factors and the last number has 2 a one of its factors

Answers

Answer:

10, 11 and 12.

Step-by-step explanation:

A number has 5 as one of its factors, when last digit is 5 or 0. Only prime numbers have 1 as the only factor and a number has 2 as one of its factors when last digit is 2, 4, 6, 8 or 0.

Three possible consecutive numbers are 10, 11 and 12. 10 is the product of 2 and 5, 11 is a prime number and 12 is the product of 3 and 2². Therefore, possible choice is 10, 11 and 12.

A recipe uses 1/3 cup of brown sugar to make 18 cookies. How many cups of brown sugar are needed to make 45 cookies?

Answers

Answer:

5/6 of a cup of brown sugar

Step-by-step explanation:

45 divided by 18 equals 2.5.

So, 2.5 times 1/3 of a cup equals 5/6 of a cup of brown sugar.

The number of cups of brown sugar needed is 5/6 cups.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The ratio of brown sugar to cookies is [tex]\frac{1}{3}[/tex]  : 18. In order to determine the amount of brown sugar needed for 45 cookies, use this formula:

Number of cookies = (45 x  [tex]\frac{1}{3}[/tex] ) / 18 = 15 / 18 = 5/6

Micah went to the grocery store the other day and there were no price tags on anything! She bought 3 loaves of bread and 1 milk jug and when the cashier scanned it, the total was $9. Then she saw the person behind her bought 1 loaf of bread and 2 milk jugs. His total was $5.50. Micah walked out wondering: how much does one loaf of bread cost?

Answers

Answer:

$2.75

Step-by-step explanation:

We know that the random persons total was $5.50. To figure out how much one loaf of bread costs we must first, divide $5.50 by 2. We get 2.75. Then, to double check our answer we multiply that by 3 to get 8.25. We know that Micah' s total was $9.00. 9 minus 8.25 equals 0.75.

That price is very reasonable, for a jug of milk, so we know that $2.75 is the answer.

Solve each problem by forming a pair of simultaneous equations:
Find two numbers with a sum of 15 and a difference of 4.​

Answers

Answer:

5.5, 9.5

Step-by-step explanation:

Let x and y be the numbers

x+y = 15

x-y = 4

Add the two equations together to eliminate y

x+y = 15

x-y = 4

------------------

2x = 19

Divide by 2

2x/2 =19/2

x = 9.5

Now find y

x+y = 15

9.5+y = 15

Subtract 9.5

x = 15-9.5

x =5.5

Answer:

11/2 and 19/2

Step-by-step explanation:

We have to make a system of equations:

1) X + Y = 15

2) X - Y = 4

Working on the first one:

X = 15 - Y

And now let's plug it in the second one:

(15 - Y) - Y = 4

15 - 2Y = 4

2Y = 11

Y = 11/2

Let's substitute this in one of the two equations:

X + 11/2 = 15

X = 19/2

Step-by-step explanation:

In 2005, the population of a town was 17,500. Suppose the population grows exponentially at a rate of 3% per year. Write an equation to model this situation, let x represent the number of years since 2005.

Answers

Answer:

The expression is:  [tex]p(x) = 17500*(1.03)^x[/tex]

Step-by-step explanation:

Since we're starting our count in 2005, then let's call that year 0 and every year after that will be 2005 + x, where t grows from 0 as an integer.

In 2005 the population is:

[tex]p(0) = 17500[/tex]

In 2006 the population is:

[tex]p(1) = 17500*(1 + \frac{3}{100}) = 17500*(1.03)[/tex]

In 2007 the population is:

[tex]p(2) = p(1)*(1.03) = 17500*(1.03)*(1.03) = 17500*(1.03)^2[/tex]

In 2008 the population is:

[tex]p(3) = p(2)*(1.03) = 17500*(1.03)^2*(1.03) = 17500*(1.03)^3[/tex]

We can notice a pattern that the population pf the city is equal to the number of the starting population multiplied by the rate of change powered by the number of years after 2005. Therefore a generic expression for the population of that town can be written as:

[tex]p(x) = 17500*(1.03)^x[/tex]

Answer:

This situation represents exponential growth

The rate of growth or decay, r, is equal to 0.10

So each year the number of residents in the town is 1.10 times the number in the previous year.

There were around 14,641 residents in the town 4 years after 2005.

Step-by-step explanation:

Since the number of residents increases by a constant percentage each year, this situation represents exponential growth.

The number of residents increases by 10% per year. So the rate of growth, r, is 10%, or 0.1.

Use the equation  to find b, the growth factor by which the population increases each year.

So the population increases by a factor of 1.1 each year. This growth factor means that the number of residents in the town in any year is 1.1 times the number in the previous year.

Write the exponential expression to model the town’s growth by substituting 10,000 for A and 1.1 for b in the general form of the exponential expression.

Set this expression equal to 14,641, and isolate the exponential term.

Use a table of values to rewrite 1.4641 as a value with a base of 1.1.

So there were around 14,641 residents in the town 4 years after 2005.

Answers

Answer:

WILL MARK BRAINLIEST!! Lorri took a 240 km trip to Waterloo. On her way there, her average speed was 120 km/h. She was stopped for speeding, so on her way home, her average speed was 80 km/h. What was her average speed, in km/h, for the entire round-trip?

Answers

Answer: Her average speed was 480 km/ 5h which is 96.

Step-by-step explanation: When she went there her speed 120 km/ h and if the distance was 240 km, then it took her 2 hours to get there. 240 divided by 120 is 2. When she returned her average speed was 80 km/h and since the distance was 240, 240 divided by 8 is 3 which means it took her 3 hours to get back home. She drove a total of 480 km , because the distance to the trip was 240 and the distance from the trip to the back was 240. 240 + 240 is 480. She drove a total of 480 km in 5 hours because it took her 2 hours to go there and 3 hours to come back . 480 km / 5h

What is 2.18 as a fraction

Answers

Answer:2 9/50

Step-by-step explanation:

2 18/100

Simplifies to 2 9/50

Answer:

109/50

Step-by-step explanation:

First, let's split this number up.

2.18 = 2.00 + 0.18

Remember that 0.18 means 18 hundredths, which can be represented as 18/100. Simplified, this equals 9/50.

Now, we have the mixed number 2 9/50.

Remember how to turn a mixed number into a fraction? Multiply 2 by 50, then add 9! That's the numerator. The denominator will be 50, the denominator of the fraction in the mixed number.

2 9/50 in fraction form is 109/50.

This is the simplest form!
