Answer : 40,000

Explanation : when multiplying 10 with 4,000 we get

4000 X 10 = 40,000.

As we multiply, using the chart there are 4 thousand present in the row of thousand column. When we multiply that with 10 it gets shifted to left and becomes 40,000.

the width of a rectangle is 3 in less than its length. The perimeter of the rectangle is 26 in. What is the width of the rectang
____ [38]

Answer:

ok so if we take length to be x we know width is x-3

the perimeter is the total length of sides, if you look at a rectangle you can see it has 4 sides with 2 length and 2 width. so perimeter is 2 times (x + x-3) = 26.

2x -3 = 13, 2x = 16, x = 8, 8 is length

the width is then 8-3 = 5.

Length = 8, width = 5.

A large cheese pizza costs 18 dollars.. Each topping you add on costs $1.50
Ilia_Sergeevich [38]

Answer:

1.50c +18

Step-by-step explanation:

The constant price is 18 dollars, which never changes and for every topping you get, it costs $ 1.50. Since we don't know how many extra toppings are added we write 1.50c.  This shows that the price will be determined by the number of extra toppings added. If you got no toppings, sub in 0 for c to get $ 18 .

the water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.
marin [14]

To determine the average water use, 109 people must be sampled.

1.9 gallons is the standard deviation.

E = 0.15 gallons maximum error

1.9 gallons on average

90% is the critical value.

1.645 is the 90% confidence interval.

sample size requirement,

n = (((z ÷ 2) × σ) ÷ E)²

n = (((1.645 ÷ 2) × 1.9) ÷ 0.15)²

n = ((0.8225 × 1.9) ÷ 0.15)²

n = (1.5627 ÷ 0.15)²

n = (10.418)²

n = 108.53 ≈ 109

As a result, the minimal sample size necessary to determine the mean water use = 109.

It is determined by dividing the average standard error by the squared of the sample size, and it decreases with increasing sample size. In other words, when the sample size is sufficiently big, the population mean approaches the population mean.

6th grade math help me plzzzz
balu736 [363]

Answer:

4.11

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714
