What is 520 divided by 8

Mathematics
1 answer:
erastova [34]3 years ago
7 0
First see how many times can 8 go into 52. So 8 goes 6 times, and it equals to; 48
Now subtract 48 from 52; 52-48= 4

Finally bring down the 0 next to the 4; 40

Now to get you final answer find out how many times can 8 go into 40; 5
Since it goes exactly 5 times then your final answer would be; 65
Hope this helps! :)

The researchers have also determined that the current rate of the rise in water level is twice the 1880 to 2009 rate. assuming t
Elden [556K]

Answer:

  1. x ≥ 2009
  2. 3.2x -6222.8
  3. 257.2 mm
  4. year 2100

Step-by-step explanation:

1. The problem statement tells you the function applies for year values (x) 2009 and later. The domain is real numbers greater than or equal to 2009.

__

2. We can use the distributive property to eliminate parentheses:

  3.2(x -2009) +206 = 3.2x -6428.8 +206

  = 3.2x -6222.8

__

3. Put 2025 in the equation and do the arithmetic

  g(2025) = 3.2·2025 -6222.8 = 257.2 . . . . mm

__

4. Put this value of level rise in the equation and solve for x.

  g(x) = 3.2x -6222.8

  500 = 3.2x -6222.8 . . put 500 mm where g(x) is in the equation

  6722.8 = 3.2x . . . . . . . add 6222.8

  x = 6722.8/3.2 = 2100.875

The water rise will be equal to about half a meter late in the year 2100.

A builder was building a fence. In the morning he worked 2/6 of an hour and later worked 9/10 what is a divison equation
nata0808 [166]

Answer:

2/9 times

Step-by-step explanation:

This is because 2/5 divided by 9/10 = 10/45 which if we simplify it we get 2/9  so that's why 2/9 is the right answer.

The following data show the prices of different types of outfits at a store: $2, $2, $28, $26, $25, $27, $25, $27, $26, $28, $30
wlad13 [49]

Answer:

The box plot will have its left tail longer than the right tail becuase a few exceptionally low prices make the distribution skewed to the left.                                              

Step-by-step explanation:

As seen in the attached file, the box plot has its left tail longer than the right tail because of the exceptionally low prices that is :$2

Firstly arranging the data in increasing order:

$2,$2,$25,$25,$26,$26,$27,$27,$28,$28,$30

Median of the data = 26 (since there are odd numbers)

Lower quartile (Q1) = 25

Upper quartile (Q2) = 26

By plotting the box plot we conclude that the left tail is longer than the right tail.

Function f is defined by f(x)=3/2x+c. If f(6)=1, what is the value of f(c)?
ASHA 777 [7]

Answer:

C = - 8

Step-by-step explanation:

f(x) =  \frac{3}{2} x + c \\  \\ plug \: x = 6 \\  \\ f(6) =  \frac{3}{2}  \times 6 + c \\  \\  f(6) = 3 \times 3 + c \\  \\ f(6) = 9+ c \\  \\  \therefore \: 1 = 9 + c \:  \{ \because \: f(6) = 1 \} \\  \\ 1 - 9 = c \\  \\ \huge \red{ \boxed{ c =  - 8}}\\\\f(c) =\frac{3}{2} c +(-8)\\\\\huge \orange { \boxed{ f(c) =\frac{3}{2} c -8}} \\\\

On a multiple choice test, if you randomly guessed on three questions, then what is the probability you got at least one of them
snow_lady [41]

Answer:

Number of Questions =3

Probability of giving a correct answer

                              =\frac{1}{3}

Probability of giving two correct answers

                       =\frac{2}{3}

Probability of giving all correct answers

            =\frac{3}{3}\\\\=1

Probability that at least one of them is correct

         =_{1}^{3}\textrm{C}\\\\=\frac{3!}{(3-1)! \times1!}\\\\=3 \text{ways}\\\\=\frac{1}{3} \times \frac{1}{3} \times \frac{1}{3} \\\\=\frac{1}{27}

Probability that two of them is correct

         =_{2}^{3}\textrm{C}\\\\=\frac{3!}{(3-2)! \times2!}\\\\=3 \text{ways}\\\\=\frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} \\\\=\frac{8}{27}

Probability that all of them is correct

         =_{3}^{3}\textrm{C}\\\\=\frac{3!}{(3-3)! \times3!}\\\\=1 \text{way}\\\\=1

So, Required probability

         =\frac{1}{27} \times \frac{8}{27} \times 1\\\\=\frac{8}{729}
