multiplying 31.04 by 100

B.
multiplying 31.04 by 1,000

C.
dividing 31.04 by 102

D.
dividing 31.04 by 103

Answers

Answer 1
Answer: The answer is B.

When we multiply by 1000, we move the decimal place 3 times to the right(or add 3 zeroes).

Just count the number of zeroes and move it that many places to the right(if it starts with '1').
Answer 2
Answer: multiplying 31.04 by 1000 = 31040

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 666 centimeters per minute. After 202020 minutes, the water level is 220220220 centimeters. Graph the relationship between the pool's water level (in centimeters) and time (in minutes).

Answers

Answer:

y=6x+100

The graph is drawn below.

Step-by-step explanation:

Let the minutes passed be x and height of water level be y cm.

Given:

Rate of rise of water level, m = 6\textrm{ cm/min}

When x=20\textrm{ min},y=220\textrm{ cm}

Therefore, the relationship can be expressed using the point-slope form of an equation if a line.

The point-slope form is given as:

y-y_(1)=m(x-x_(1))

Here, m=6,x_(1)=20,y_(1)=220

Therefore, the relationship is given as:

y-220=6(x-20)\ny-220=6x-120\ny=6x-120+220\ny=6x+100

Therefore, the relationship between the pool's water level (in centimeters) and time (in minutes) isy=6x+100.

The graph is shown below.

Oh: 10x + 10 < 30
Whats the graph

Answers

Answer:

See attachment

Step-by-step explanation:

The given inequality is  10x + 10 < 30.

We subtract 10 from both sides to get:

10x + 10 -10< 30-10

This simplifies to 10x < 20

Divide both sides by 10 x<3

The lot that Dana is buying for her new one story house is 35 yards by 50 yards. Dana's house plans show that her house will cover 1,600 square feet of land. What percent of Dana's lot will not be covered by the house ? Explain your answer.

Answers

35x50=1,750-1,600=150. We need to find out what 150 is of 1,600.
150/1,600=?/100 
1,600 divided by 100=16
do the same for 150
150 divided by 16=9.375

3/y=6/y-2
solve for y
please I need help

Answers

Answer:

The answer is y = -2.

Step-by-step explanation:

To start, you need to cross multiply to solve.

3/y = 6/(y -2)

y*6 = 3*(y -2)

6y = 3y - 6

3y = -6

y = -2
