Juan needs to simplify the fraction LaTeX: \frac{32}{52}32 52. He will need to divide the numerator and the denominator by the greatest common factor. What is the greatest common factor of 32 and 52?

Answers

Answer:

4

Step-by-step explanation:

Given the expression, 32/52

Juan need to divide the numerator and the denominator by the greatest common factor

For 32;

32 = 8 * 4

For 53

52 = 13 * 4

Find the ratio

32/52 = (8*4)/(13*4)

32/52 = 8/13

Since 4 is common to both factors, Hence the greatest common factor is 4

Jayana is trying to run a certain number of miles by the end of the month. If Jayana is 30% of the way to achieving her goal and she has already run 9 miles, how many miles is she trying to run by the end of the month?

A human bone is made up of water 1/4 and 9/20 minerals, and the rest is living tissue. What decimal represents the amount of a human bone that is living tissue?

Answers

Answer:

0.3

Step-by-step explanation:

First you need to add 1/4 and 9/20, and you would get 7/10. That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that human bone is made up of water 1/4 and 9/20 minerals, and the rest is living tissue.

First we need to add 1/4 and 9/20,

Thus we would get 7/10.

That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8. Many pundits claim that the worst is yet to come, with an earthquake 133,680 times as intense as the 1989 earthquake ready to hit San Francisco. If the pundits ability to predict such earthquakes were correct, what would be the magnitude of their claimed earthquake? Round your answer to the nearest tenth.

Answers

Answer:

Magnitude of claimed earthquake = 10.363 (Approx)

Step-by-step explanation:

Magnitude of claimed earthquake = log√133,680 +  7.8

Magnitude of claimed earthquake = [1/2] log 133,680 +  7.8

Magnitude of claimed earthquake = 2.563 +  7.8

Magnitude of claimed earthquake = 10.363 (Approx)

At the baseball game, the Gregory's bought 5 hot dogs and 2 hamburgers and paid $27.00. The Hart's purchases 3 hot dogs and 4 hamburgers and paid $29.50. How much does 1 hot dog cost?

Answers

Answer:

1 hot dog costs $3.50

Step-by-step explanation:

Represent Hot dog with x and Hamburger with y

Gregory's purchase:

[tex]5x + 2y = 27[/tex] --- (1)

Hart's purchase:

[tex]3x + 4y = 29.5[/tex] ---- (2)

Required

Find x

To do this, we'll make use of the elimination method of solving simultaneous equation.

Start by multiplying (1) by 2

2 * ([tex]5x + 2y = 27[/tex])

This gives:

[tex]10x + 4y = 54[/tex] ---- (3)

Subtract (2) from (3)

[tex]10x + 4y = 54[/tex]

- ([tex]3x + 4y = 29.5[/tex])

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

[tex]7x = 24.5[/tex]

Solve for x

[tex]x = \frac{24.5}{7}[/tex]

[tex]x = 3.5[/tex]

Hence:

1 hot dog costs $3.50

Answer:

One way of awarding interest is called simple interest. Before we provide the formula used in calculating simple interest, let’s first define some basic terms.

Balance. The balance is the current amount in an account or the current amount owed on a loan.

Principal. The principal is the initial amount invested or borrowed.

Rate. This is the interest rate, usually given as a percent per year.

Time. This is the time duration of the loan or investment. If the interest rate is per year, then the time must be measured in years.

To calculate the simple interest on an account or loan, use the following formula.

Simple Interest

Simple interest is calculated with the formula

I=Prt,

 

where I is the interest, P is the principal, r is the interest rate, and t is the time.

When p = 12, t= 2, and s = 5. r = 18. If r varies directly with p and inversely with the product of s and t, what is the constant of variation? O col 1 2 O O 18​

Answers

Answer:

Constant of variation is: 15

Step-by-step explanation:

r varies directly with p and inversely with the product of s and t

It can be written as:

r ∝ p/st

When the proportionality symbol is removed, a constant is introduced which is called constant of variation

So

[tex]r = \frac{kp}{st}[/tex]

Putting p = 12, t= 2, and s = 5 and r = 18

[tex]18 = \frac{k * 12}{2*5}\\18 = \frac{12k}{10}\\12k = 18*10\\12k = 180\\\frac{12k}{12} = \frac{180}{12}\\k = 15[/tex]

Hence,

Constant of variation is: 15

a copy machine can copy a report in 30 min. when a second copy machine is used at the same time, the copying can be done in 18 min. how long would it take the second copy machine to do the copying alone?

Answers

Answer:

Step-by-step explanation:

A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?

i have:

x=30

x+y=18

that would be -12..not right?

The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Calculation of the time taken:

Let we assume x be the time required at the time when using both machines.

Let us assume the completed job = 1

we know that

copy machine 1 will do [tex]x/30[/tex] of the job

and

copy machine 2 will do [tex]x/18[/tex] of the job

So, it can be like

[tex]\frac{x}{30} + \frac{x}{18} = 1[/tex]

So,

18x + 30x = 540

48x = 540

x = 11.25 minutes

hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Which equation does not represent a direct variation? Explain.

Answers

Answer:

y = 3x + 2

Step-by-step explanation:

"When x is zero in a direct variation equation y will also be zero. ... Equations of the form y = kx + b where b is a number other than zero are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx."

in short, y = 3x + 2 can't be turned into y = kx

you could also immediately tell it's y = 3x + 2 because it includes + 2
