Answer:

1. -141

2. 0.98

3. 62.13

Step-by-step explanation:

1. 35 - 176 -> 176 - 35 = 141, then just make it negative

2. 0.55 x 1.79 = 0.9845 -> 0.98

3. 11.38 x 5.46 = 62.1348 -> 62.13

Answer:

48

Step-by-step explanation:

Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.

Here is 8 divided by 1/6 displayed mathematically in colors:

8

 ÷    

1

6

The numbers in 8 divided by 1/6 are labeled below:

8 = whole number

1 = numerator

6 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

8 x 6

1

 =  

48

1

Thus, the answer to 8 divided by 1/6 in fraction form is:

48

1

To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

48 / 1 = 48

The answer is rounded to the nearest two decimal points if necessary.

48/1 is an improper fraction and should be written as 48.

Answer:

12 = 2 x 2 x 3

48 = 2 x 2 x 2 x 2 x 3

8 = 2 x 2 x 2

21 = 3 x 7

9 = 3 x 3

81 = 3 x 3 x 3 x 3

75 = 3 x 5 x 5

38 = 2 x 19

44 = 2 x 2 x 11

Step-by-step explanation:

(Can't really show your work for this. But I can give exponential form if you need it.)

Prime Factorization is basically just multiplying prime numbers to get a specific number.

I hope it helps! :)

Answer:

see image

Step-by-step explanation:

It is difficult to show work, unless you were taught to use a factoring tree (see image) or division tower (see image).

On the tree, the bottom row shows the final answer. On the towers, the prime factors all end up on the left or under the tower.

Basically, divide your number (the question/problem) by 2 if its an even number. And keep dividing by two until its not an even number anymore. Then divide by the next smallest prime number that goes into it (like 3 or 5 or 7 or 9 or 11...) When the result is a prime number, then you are done. See image.

make me brainliest if u r satisfied

price of one message = 1.35 ÷ 9

1.35 ÷ 9 = 0.15

0.15 • 118 = ( 3 ÷ 20 ) • 118

118 • 3 = 354

354 ÷ 20 = 177 ÷ 10 = $17.7 to send 118 messages

Answer:

Triangle A: Acute

Triangle B: Obtuse

Triangle C: Acute

Triangle D: Right

Step-by-step explanation:

Acute angle: 0°-90°

Right angle: 90°

Obtuse angle: 90°-180°

An acute triangle only has acute angles. A right triangle has one right angle and two acute angles. An obtuse triangle has one obtuse angle and two acute angles.

Answer:

It would be 66,000

Step-by-step explanation:

you round to the number next to you some saying I learned were 5 and above give it a shove 4 or less give it a ress.

example 598 round to nearest hundred would be 600 because the 9 is 5 and above so answer 600

Answer:

$23.97 is the sales tax

Step-by-step explanation:

5.5% ÷ 100 = 0.055

0.055 x 435.78 = 23.9679

round to nearest hundredth

= 23.97

Answer:

4 Hours and 15 Minutes

Step-by-step explanation:

1 Hour = 52

221/52 = 4.25

4 hours, 15 minutes

For example 15 minutes (¼ hour) equals . 25, 30 minutes (½ hour) equals . 5, etc.

As there is no graph attached so you have to done it yourself, Steps provided below for making it easier.

Answer:

A. The triangles are not similar to each other.

Step-by-step explanation:

[] A triangle's angles all add up to 180°

-> For triangle ABC the angles are 80°, 40°, and unknown

-> For triangle DEF the angles are 80°, 70°, and unknown

[] For triangle ABC the angles are 80°, 40°, and unknown

-> 180° - 80° - 40° = 60°

-> Triangle ABC has angles of  80°, 40°, and 60°

[] For triangle DEF the angles are 80°, 70°, and unknown

-> 180° - 80° - 70° = 30°

-> Triangle DEF has angles of 80°, 70°, and 30°

[] A. The triangles are not similar to each other.

-> Since we do not have any side lengths, we must go off of AA (angle & angle) but as AA is not true, these triangles are not similar

Step-by-step explanation:

Answer:

10.06 lbs of peanuts and 19.94 lbs of hazelnuts.

Step-by-step explanation:

lb=pound

30 lb mixture at $6.43/lb means that the total cost of the mixture is 30×6.43=192.9

Let H = weight of hazelnuts in the mixture.

Let P = weight of the peanuts in the mixture.

Set up a system of equations.

7H + 6.43P = 192.9

H + P = 30

Afterward, input the values into the equations above.

H = 30 - P

7(30-P) + 5.3P = 192.9

210 - 7P + 5.3P = 192.9

210 - 1.7P = 192.9

-1.7P + 210 = 192.9

-1.7P = 192.9 - 210

-1.7P = -17.1

P = -17.1 / -1.7 = 10.06

H = 30 - P = 30 - 10.06 = 19.94

Hence, the mixture contains 10.06 lbs of peanuts and 19.94 lbs of hazelnuts. Hope this helps and have a great day!
