Answer:

terminating

Step-by-step explanation:

if the given fraction is terminating then prime factors of denominator should be 2^n x 5^m where m and n are whole number

5=1x5=2^0x5^1

so it is of form 2^nx5^m

Answer:

Step-by-step explanation:

1). By definition of an exterior angle of a triangle,

  Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.

  From the figure attached,

  m∠4 = m∠1 + m∠2

2). Property of a triangle states that " sum of interior angles of a triangle is 180°"

   Therefore, m∠1 + m∠2 + m∠3 = 180°

Answer:

h= -2

Step-by-step explanation:

Move the terms,

19 + 4h = 1 -5h

Combine like terms,

4h+5h=1-19

Divide both sides...

9h= -18

-18/9 = -2

Answer:

h=-2

Step-by-step explanation:

17+4h+2=1-5h

19+4h=1-5h

-1 -1

18+4h=-5h

-4h -4h

18=-9h

18/-9=-9h/-9

h=-2

Answer:

3 1/8

Step-by-step explanation:

6 1/4 ÷ 2

~Turn each number into an improper fraction

25/4 ÷ 2/1

~Copy Dot Flip

25/4 * 1/2

~Multiply

25/8 or 3 1/8

Best of Luck!

When the mixed number i.e. [tex]6\frac{1}{4}[/tex] is divided by 2 so the answer is [tex]3 \frac{1}{8}[/tex]

Given that,

Based on the above information, the calculation is as follows:

[tex]= 6\frac{1}{4} \div 2\\\\= \frac{25}{4} \div 2\\\\= \frac{25}{4} \times \frac{1}{2} \\\\= \frac{25}{8}\\\\= 3 \frac{1}{8}[/tex]

Therefore we can conclude that when the mixed number i.e. [tex]6\frac{1}{4}[/tex] is divided by 2 so the answer is [tex]3 \frac{1}{8}[/tex]

Answer:

100 sq m

Step-by-step explanation:

if you fill in the shape to be a big rectangle it will be 8 x 22 =176 sq m

then the little piece on the left that is taken out is 2 x 2 = 4 sq m

the piece on the right is 6 x 12 = 72 sq m

so subtract them from the big rectangle

176 - 4 - 72 = 100 sq m

Answer:

100m^2

Step-by-step explanation:

To do this we need to break the shape into sections as illustrated in the picture I attached, I color coded the squares to make it easier to explain. Now we just find the area of each shape and add them all together.

Area= base•height

So for the purple shape:

6•2=12

Orange:

8•8=64

Green:

2•12=24

In total:

12+64+24=100

And since it's area it would be in square units which just means it'd look like this:

[tex] {100m}^{2} [/tex]

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer: 46 years old

Step-by-step explanation: If Devaughn is 13 years younger than Sydney,

we can represent Sydney's age as x and Devaughn's age as x - 13.

Since the sum of their ages is 79, we have x + x - 13 = 79.

This simplifies to 2x = 92.

Dividing both sides by 2, we have x = 46.

So sydney is 46 years old.

Answer:

y=6

Step-by-step explanation:

75-3.5y-4y=4y+6

combine like terms)

75+(-3.5y-4y)=4y+6

75-7.5y=4y+6

add 4y to each side to combine the terms) 75+(-7.5y-4y)=6

75-11.5y=6

subtract 75 from each side to isolate the variable) -11.5y=-69

divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5

y=6

19 y= 7×38

19y= 266

y= 266/19

= 14

Hence there are 14 ounce of oil present

Answer:

13 percent

Step-by-step explanation:

Single decimal multiplier used to decrease by 7% followed by a 20% decrease is 0.744.

A percentage multiplier is a number which is used to calculate a percentage of an amount or used to increase or decrease an amount by a percentage. In order to use a percentage multiplier to calculate the percentage of an amount, convert the percentage to a decimal by dividing by 100 ; this is the decimal multiplier.

Given,

First decrease = 7%

Second decrease = 20%

Let a number be x.

If x is decreased by 7% then the value of the number is

( (100 - 7) / 100) × x = 0.93 x

Again if 0.93 x is decreased by 20% then the value of the number      ((100 - 20) /100) × 0.93 x = 0.744 x

Hence, The single decimal multiplier is 0.744.

Answer:

∛-27 or -3

Step-by-step explanation:

I don't think you can do anything further to this problem unless we have to solve for something.

If it is 3 square root of the whole thing, then the answer is -3 because

-3 x -3 x -3 = -27

-3 x -3 = negative x negative = positive = 9

9 x -3 = positive  x negative = negative = -27

Answer:

3°C > - 2°C

Step-by-step explanation:

Ice cream 1 = - 2°C

Ice cream 2 = 3°C

Lower temperatures are colder (cooler) than higher temperature values.

Hence, ice cream at - 2°C is cooler than ice cream at 3°C.

Hence, a temperature of 3°C is higher (greater) than - 2°C. Hence - 2°C is cooler (colder) than 3°C

Hence,

3°C > - 2°C

Answer:

40y^5√6y (B)

Step-by-step explanation:

Let's multiply 2√25y^8 * 4√6y^3:

8√150y^11 (When you multiply exponents with the same base, you can just add the exponents and keep the same base:

Ex. 4^5 * 4^9 = 4^14)

Let's simplify 8√150y^11

√150 = 5√6

√y^11 = y^5√y

So our final answer would be:

40y^5√6y
