Any non-zero digit is significant.Any trailing zeros after the decimal is significant.Any zeros between 2 significant digits are significant.Zeroes before significant numbers in the decimal place are NOT significant; they are placeholders.

(a)

0.004816 - the zeros are placeholders, so they do not count as sig figs.

(b)

50.00168 - the zeros are between 2 significant figures, so they do count as sig figs.

(c)

A pair of parallel lines is cut by a transversal:

A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees.

8y + 7x = 9 for x

Answers

Answer:

x = 9-8y/7

Step-by-step explanation:

8y+7x=9

Subtract 8y from both sides.

7x=9−8y

Divide both sides by 7.

7x/7 = 9 - 8y/7

​  

 

Dividing by 7 undoes the multiplication by 7.

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation

Answers

Answer:

5 - (1 + 20) = yx

Step-by-step explanation:

So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

Andrew participated in a bicycle race. The total distance covered was 56
miles. If he cycled at a constant rate of 14 miles per hour, how much time
did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.

Answers

(B) 4 hr is the correct answer.

Explanation :

★ Speed of body is defined as the ratio of distance travelled to the time taken[tex].[/tex]

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

time = 4 hr

In a neighborhood of 72 families. 18 families on one or more cats. Write the number of families who own one or more cat as a fraction. Then write the fraction as a decimal.

Answers

Answer:

0.25

Step-by-step explanation:

The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the  answer is 0.25

Match each solution to the equation it solves.

Answers

Answer:

the first one is 3

the second one is 7

the third one is -2

and the last one is -3

Step-by-step explanation:

The equation is matched with its solutions below;

1/4x + 5/3x - 4 = 2 - 1/12x; x = 33.2b - 4.7 = 3b - 3.3; b = 74.6y - y + 4 = y - 1.2; y = -27.5c - 2.5c + 8 = - 7; c = -3

What is the solution to the equation?

1/4x + 5/3x - 4 = 2 - 1/12x

combine like terms

1/4x + 5/3x + 1/12x = 2 + 4

(3x+20x+x) / 12 = 6

24/12x = 6

2x = 6

Divide both sides by 2

x = 6/2

x = 3

3.2b - 4.7 = 3b - 3.3

combine like terms

3.2b - 3b = -3.3 + 4.7

0.2b = 1.4

divide both sides by 0.2

b = 1.4 / 0.2

b = 7

4.6y - y + 4 = y - 1.2

combine like terms

4.6y - y - y = - 1.2 - 4

2.6y = - 5.2

divide both sides by 2.6

y = -5.2 / 2.6

y = -2

7.5c - 2.5c + 8 = - 7

5c = -7 - 8

5c = -15

divide both sides by 5

c = -15/5

c = -3

Please explain how you solved it too! Thank you!

Answer:

joe=6

Sam=11

Step-by-step explanation:

lets see...

i explain 1by1

firstly we know that joe is 5 - 3 x Sam

(read the sentences VERY CAREFULLY)

then, we put Sam as math variable "s"

it will be; 5-3 x S

[tex]5 - 3 \times s[/tex]

the total of their age is 28

[tex]5 - 3 \times s = 28[/tex]

simplify it

it will be 5-S3=28

then you will get 11 right

that will be sam's age

-5 and it will be Joe's age

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30.75 altogether. How much money did each boy receive?

Answers

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.
