Jeff is baking a cake. The recipe says that he has to mix 32 grams of vanilla powder to the flour. Jeff knows that 1 cup of that particular vanilla powder has a mass of 128 grams. He added two over three of a cup of vanilla powder to the flour. Should Jeff add more vanilla powder to make the exact recipe, or did he go over and by what amount?

Answers

Jeff has added 53.33 grams more vanilla powder than the recipe.

The recipe calls for 32 grams of vanilla powder, and we need to compare this to the amount Jeff used.

Jeff added two-thirds of a cup of vanilla powder to the flour. Since 1 cup of vanilla powder is 128 grams, two-thirds of that amount can be calculated as follows:

(2/3) × 128 grams = 85.33 grams (rounded to two decimal places).

Comparing this to the requested 32 grams, Jeff has added more than the recipe asks for:

85.33 grams - 32 grams = 53.33 grams.

A magazine photographed is 24 cm long and 16 write each ratio

Answers

Since the length is 24 and the width is 16, we have the length to width ratio equal to 24/16. Since 8 goes into 24 3 times and into 16 2 times, we have 3/2. For width to length, we have 16/24=2/3 using the same reasoning as last time (except the numerator and denominator are flipped)
Final answer:

The requested ratios of the width to length and length to width of the magazine photograph are 2:3 and 3:2 respectively.

Explanation:

The question is asking for the ratios relating to the dimensions of the magazine photograph. In this case, the photo is 24 cm long and 16 cm wide. Therefore, you can derive various ratios from this.

The first is the ratio of width to length, which is 16 : 24. This can be simplified by finding the highest common factor of 16 and 24, which is 8. So divide both sides of the ratio by 8 to get 2 : 3.

Another ratio is the ratio of length to width, which is 24 : 16. Similarly, this can be simplified to a ratio of 3 : 2 by dividing both sides by 8.

If a revolving restaurant can rotate 270° in 45 minutes, how long does it take for the restaurant to make a complete revolution?

Answers

the answer is one hour. 360-270=90 90 is a fourth of 360. 45 minutes is 3/4 of an hour so yeah

270/360 = 0.75 = 3/4 of a complete revolution


45 minutes = 3/4 of an hour

 so it is doing 1/4 of a revolution every 1/4 hour

 so it would take 1 hour to do a complete revolution

n<1.3


Ken and Hamid run around a track. It takes Ken 80 seconds to complete a lap. It takes Hamid 60 seconds to complete a lap. Ken and Hamid start running at the same time from the start line. How many laps will they each have run when they next meet on the start line?

Answers

The correct answer is:

Ken will have run 3 laps and Hamid will have run 4.

Explanation:

To find this, we first find the number of seconds that will have passed when they meet again.  We use the LCM, or least common multiple, for this.  First we find the prime factorization of each number:

80 = 10(8)

10 = 5(2)

8 = 2(4)

4 = 2(2)

80 = 2(2)(2)(5)(2)

60 = 10(6)

10 = 5(2)

6 = 2(3)

60 = 2(2)(3)(5)

For the LCM, we multiply the common factors by the uncommon.  Between the two numbers, the common factors are 2, 2 and 5.  This makes the uncommon 2, 2, and 3, and makes our LCM

2(2)(5)(2)(2)(3) = 240

This means every 240 seconds they will both be at the start line.

Since Ken completes a lap in 80 seconds, he completes 240/80 = 3 laps in 240 seconds.

Since Hamid completes a lap in 60 seconds, he completes 240/60 = 4 laps in 240 seconds.

Ken will have run [tex]3[/tex] laps and Hamid will have run [tex]4[/tex] laps when they next meet on the start line.

Take LCM of [tex]80,60 =240\\[/tex]

After every [tex]240[/tex] seconds they will both be at the start line.

So in [tex]240[/tex] seconds Ken covered

[tex]\dfrac{240}{80}=3laps\\[/tex]

So in [tex]240[/tex] seconds  Hamid covered

[tex]\dfrac{240}{60}=4laps\\[/tex]

Ken will have run  [tex]3[/tex] laps and Hamid will have run [tex]4[/tex] Laps.

how to solve the equation 9v = 8 + v

Answers

Here are some things you should know when solving algebraic equations.

If you add an expression to both sides of an equation, the resulting equation will have the same solution set as the original equation. In other words, they will be equivalent. This is true for all operations. As long both sides are treated the same, the equation will stay balanced.

You will also need to know how to combine like terms. But what are like terms to begin with? Like terms are defined as two terms having the same variable(s) (or lack thereof) and are raised to the same power. In mathematics, something raised to the first power stays the same. So, 5x and 10x are like terms because they both have the same variable and are raised to the first power. You don’t see the exponents because it doesn’t change the value of the terms.

To combine like terms, simplify add the coefficients and keep the common variable(s) and exponent.

The distributive property is another important rule you will need to understand.

The distributive property is used mostly for simplifying parentheses in expressions/equations. 

For example, how would you get rid of the parentheses here?

6(x + 1)

If there wasn’t an unknown in between the parentheses, you could just add then multiply. That is what the distributive property solves. The distributive property states that a(b + c) = ab + ac

So, now we can simplify our expression.

6(x + 1) = 6x + 6

Now let's solve your equation.

9v = 8 + v
8v = 8 <-- Subtract v from each side
v = 1 <-- Divide both sides by 8

So, v is equal to 1.

Scientific notation are super long numbers that are shortened by a decimal and an exponent. In my opinion, it's much more fun to write zeroes over and over, but nobody cares about my opinion, haha. 
So how to make a number a scientific notation:
Step one: Identify the number. (ex. 0.000025)
Step two: Get rid of the zeroes for a second. We will get to that later. (25)
Step three: Put a decimal point between the two numbers. If there are three or more, but the decimal point before the last left number. (2.5)
Step four: Break! (math is boring at times)
Step five: Put the decimal into the scientific notation format. A scientific notation format is _._*10^_. The blanks represent the places that the numbers should go into. The power can be negative or positive, more on that later. For this equation, we will put the decimal before the times 10. (2.5*10^_)
Step six: Now we have to determine the value of the power. That is very easy. First, let’s go back to the decimal. 0.000025. Since we put the after decimal point between 2 and 5, We will count to the other initial decimal point. For this one, there are 5 decimal points. So that means the value of the power is 5. If the original number was positive, you would put the decimal point into the large number, count the number of well….numbers there are between the decimal point and the last number.
Step seven: Set it up! (2.5*10^5)Done!!!
For number two, 2x10^-4(sand)/1x10^-5(cell) = 2x10^1. SO this means the answer is 20 times.

Halle is hiking down into a canyon. She descends 3,000 ft in 1 3/4 hours. To the nearest foot, what number shows her descent per hour?

Answers

What we are asked to find out is speed per hour. To find speed, divide distance by time. Distance is 3000 ft and time is 1 3/4 hr. To make calculations easier, let us convert time into minutes. 1 hour is 60 minutes and 3/4 hour is 45 minutes. So total minutes is 105. Now let us divide 3000 by 105. We get 28.57 ft per minute. Now multiply this number by 60 to convert speed per minute into speed per hour. 28.57 * 60 = 1714 ft in 1 hour.

What is 0.46 repeating as a fraction

Answers

Umm, assuming in this case it would be 0.4646464646464646...

Then you would just assign it a variable in the beginning:

x = 0.46464646...

Then multiply it by 100, to get:

100x = 46.46464646464646...

Now you just want to subtract x from 100x, or

46.464646464646464646... - 0.46464646464646...

Which would result in 99x = 46.

Now just divide 99 from both sides to get:

x = 46/99

So it would be 46/99.
