Answer:

1.6296*[tex]10^8[/tex]

Step-by-step explanation:

To do this problem, factoring skills are helpful
Step 1: See if both the terms (numbers) have a common factor. In this case, it's both [tex]10^7[/tex], so we can rewrite the equation as this (below) by pulling out the common factor.

(10^7)(9.54+6.756)
Solve the inside of the paranthasis to get
16.296*10^7
We're not done yet, as scientific notation requires the number in front to be from 1-9.999...
factor out a 10 from 16.296 to get 10*(1.6296)
replace the 16.296 with (1.6296)*10 to get:
1.6296*10*10^7, and combine 10*10^7 to get 10^8
final answer:  1.6296*10^8


side note: 10^7 = [tex]10^7[/tex], the upside down V indicates exponents, and 10=10^1

Answer:

1/36

Step-by-step explanation:

(1/4 times 2/3)^2

cancel out greatest common factor (2)

(1/2 times 1/3)^2

multiply

(1/6)^2

1/36

Answer:

[tex]\textsf{B)}\quad \dfrac{1}{36}[/tex]

Step-by-step explanation:

[tex]\textsf{Simplify}\quad \left(\dfrac14\right)^2 \cdot \left(\dfrac23\right)^2[/tex]

[tex]\textsf{Apply exponent rule}\quad \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}:[/tex]

[tex]\implies \left(\dfrac{1^2}{4^2}\right) \cdot \left(\dfrac{2^2}{3^2}\right)[/tex]

[tex]\implies \dfrac{1}{16} \cdot \dfrac{4}{9}[/tex]

[tex]\textsf{Apply the fraction rule}\quad \dfrac{a}{b} \cdot \dfrac{c}{d}=\dfrac{a \cdot c}{b \cdot d}:[/tex]

[tex]\implies \dfrac{1\cdot 4}{16 \cdot 9}[/tex]

[tex]\implies \dfrac{4}{144}[/tex]

[tex]\textsf{Simplify by dividing the numerator and denominator by the GCF of 4}:[/tex]

[tex]\implies \dfrac{4 \div 4}{144 \div 4}[/tex]

[tex]\implies \dfrac{1}{36}[/tex]

Answer:

$ 46.75

Step-by-step explanation:

45% OFF means you pay 55% of original price

.55 * 85 =

Answer:

$46.75

Step-by-step explanation:

1% of $85 is 85/100 = $0.85

To find 45% of $85:  0.85 * 45 = $38.25

So the sale price is $85 - $38.25 = $46.75

Answer:

A. 2/3

Step-by-step explanation:

Simplify it by four, 8 / 4 = 2, 12 / 4 = 3

Answer:

A 2/3

Step-by-step explanation:

You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number.

So 8 and 12 are both divisible by 4

8/4=2

12/4=3

so the answer would be 2/3

Answer:

In 42 minutes

Step-by-step explanation:

Multiples of 14: 14, 28, 42, 56, 70, 84

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54

We have to find the LCM.

The LCM is 42. So it takes 42 minutes to be made at the same time again.

Answer:

13

Step-by-step explanation:

First, we need to find out what 180 - 154 is because a straight line has a 180-degree angle.

180 - 154 = 26

Next, we need to divide 26 by 2 to get the angle of both sides.

26 / 2 = 13.

Answer:

1.

-9 11/15

2. 11/24

3.

34/45

4. -5.05

5. -0.622

Step-by-step explanation:

1. -2 4/5 - 6 2/15

convert them to a common denominator and an improper fraction:

-2 4/5= 18/5=- 54/15 -6 2/15= 92/ 15

*15 is the other denominator, so you keep the numbers in the second number the same*

subtract: -54/15- 92/15

since you are subtracting a negative number it goes farther away from zero

-146/15 or -9 11/15

2. -5/12 + 7/8

convert them to a common denominator

-5/12=- 20/48 7/8= 35/40

add: -20/48+35/40

11/24

since you are adding a negative number it goes closer to zero or past zero:

3. 3 3/5 x 2/9

convert 3 3/5 to an improper fraction: 18/5

mulitply the two denominators and the two numerators

17/5 x 2/9= 34/45

This is also the simplest form.

4. Convert to a decimal. -5 1/20

keep the -5 beacuse that is a whole number

divide 1/20 to turn it to a decimal to get 0.05

5. Which number is the largest? -0.65, -0.622, -5/8

to find this you would have to convert all numbers to either a decimal or a fraction.

5/8 is 0.625

the one closest to zero is the largest which is -0.622

Answer:

A

Step-by-step explanation:

So, what you do is 913 divided by 29 is 31.482 and so on, but when you round it and turn it into a mixed fraction, it's 31 in 14/29.

from 1 the fifth is:2*5+1/3=10 1/3

rule 2:（n+1/2） *4

from 0 the fifth is:（4+1/2） *4 =18

the answer is (10 1/3, 18)

Step-by-step explanation:

there awnser got deleted so im making this one so you will know

Answer:

Make sure that everything is the same format, and then add numbers.

Step-by-step explanation:

1. Covert 3/4 into a decimal.

2. Draw a line.

3. Add numbers to it.

4. Mark up the points that were given.

Answer:

The first thing that we will need to do is to convert 3/4 into a fraction which would give us 0.75 and now we can continue.  We then draw a line that starts with zero and we can increment by 0.25 until we reach around 2.  We then label each of the increments and plot our points and make sure that they are correct.
