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: I'm pretty sure that A=Right B= Obtuse C= Acute and D= Obtuse

Step-by-step explanation:

A right angle is equal to 90°. An Acute angle is less than 90°. And an Obtuse angle is greater than 90°.

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:

the answer is (10 1/3, 18)

Step-by-step explanation:

rule 1: 2n+1/3

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)

there is no right answer.

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:

$ 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

Hope this helps!

Answer:

22

Step-by-step explanation:

okay first you add all of them up 22 + 25 + 12 + 25 + 26 =110

then divide 110/5=22

Answer:

Range: 7-4=3

Mode : 7

Range subtract the highest with the lowest value.

Mode the number that occurs the most.

Answer: Range= 9-4=5

Mode=7

Step-by-step explanation: Range is Highest value minus lowest value

Mode is the most occuring number

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:

1.6296*[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
