What is the answer to : 20 / 2(5+5)

Answers

Answer 1

Answer:

Answer:

100

Explanation:

Before we begin, you should remember the order of operations from left to right:

1- Parentheses

2- Exponential

3- Division/multiplication

4- Addition/subtraction

Now , the given is:

$(20)/(2) * (5+5)$

We will start by resolving the brackets:

5+5 = 10

Therefore, the expression now is:

$(20)/(2) * 10$

Note that multiplication/division both have the same rank in the order of operations. This would mean that we will go from left to right and resolve whichever of them comes first.

In our expression, we can see that division comes first. So, we will start by division:

$(20)/(2) = 10$

The expression now became:

10 * 10

We will finally do the multiplication:

This would give us the final answer 100.

Combining all the above steps:

$(20)/(2) * (5+5) = (20)/(2) * 10 = 10 * 10 = 100$

Hope this helps :)

Answer 2

Answer:

100

Further explanation

In the 1500s special rules of order of operations were issued. This sequence of work states which process takes precedence as the priority before other operations.

Operation priorities are as follows.

Parentheses (simplify in it)
Exponent
Multiplication or Division (from left to right)
Addition or Subtraction (from left to right)

Let's implement the rule.

$\boxed{ \ 20/2(5 + 5) \ } \rightarrow \boxed{ \ 20 / 2 (5 + 5) = \ ? \ }$

Inside the brackets, do the addition.

$\boxed{ \ 20 / 2 (10) = \ ? \ }$

Let us apply rule number 3 from the priority operation above. Operate on the left to right. We have to divide 20 by 2.

$\boxed{ \ 10(10) = \ ? \ }$

The continuous operation ends with multiplication.

$\boxed{ \ 10 * 10 = 100 \ }$

Thus, the answer is

$\boxed{ \ 20/2(5 + 5) \ } \rightarrow \boxed{\boxed{ \ 20 / 2 (5 + 5) = 100 \ }}$

Notes:

What if we don't follow the priority of the operation?

Look carefully at the following discussion.

At this crucial point:

$\boxed{ \ 20 / 2 (10) = \ ? \ }$

We decide to multiply 2 by 10, even though there are no parentheses from them, only parentheses for 10.

$\boxed{ \ 20 / 2 * 10 = \ ? \ }$

$\boxed{ \ 20 / 20 = 1 \ }$

Hence, $\boxed{ \ 20 / 2 (5 + 5) = 1 \ }$

That's what happens if we don't follow operating priorities.

Unless the problem like this:

$\boxed{ \ 20 / (2 (5 + 5)) = 1 \ }$

$\boxed{ \ 20 / (2 * 10) = 1 \ }$

$\boxed{ \ 20 / 20 = 1 \ }$

Thus, the difference must be considered. Consequently, obey the priority of the operation and look at the problem in detail.

2:5 and 30:20 are equal ratios. True or false

Answers

The answer is false.
For being in equal ratios, product of means = product of extremes
2:5 :: 30:20
2 × 20 = 30 × 5
40 ≠ 150
So, its false since they are unequal.

Question 2 (Multiple Choice Worth 6 points)(09.03 LC)

Tanya drives to work every day and passes two independently operated traffic lights. The probability that both lights are red is 0.55. The probability that the first light is red is 0.69. What is the probability that the second light is red, given that the first light is red?
0.83
0.75
0.80
0.73

Answers

Answer:

Step-by-step explanation:

Let the probability that the first light is red is= $P_(1)$ and

the probability that the second light is red= $P_(2)$ . Then,

Probability that both lights are red= $P( P_(1) and P_(2) )$ = 0.55,

Probability that the first light is red= $P(P_(1))$ =0.69,

Probability that the second light is red, given that the first light is red= $P( P_(2) /P_(1))$ = $(P(P_(1) and P_(2)) )/(P(P_(1)) )$

= $(0.55)/(0.69)$

= $0.7971$

≈ $0.80$

Given:
Probability that both lights are red 0.55
Probability that 1st light is red 0.69

Find the probability that the 2nd light is red, given that the first light is red.

0.55/0.69 = 0.797 or 0.80

The probability that the 2nd light is red while the 1st light is also red is 0.80.

Tom wants to tile the floor in his kitchen which has an area of 320 ft.² in the store the smallest tile he likes has an area of 1.1 square feetand the largest tile he likes has an area of 1.815 ft.² about how many tiles can be fitted in the given area

Answers

The 291 smallest tile or 177 largest tile.

What is Area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

The area of a shape is calculated with the help of its length and width. Length is unidimensional and measured in units such as feet (ft), yards (yd), inches (in), etc. However

Given:

Area of floor = 320 feet²

Area of smallest tile= 1.1 square feet

Area of smallest tile = 1.815 square feet.

Number of smallest tile = 320/1.1 ≈ 291 tiles

Number of large tiles = 320/1.815 ≈ 177 tiles

Hence, the 291 smallest tile or 177 largest tile.

#SPJ2

To use the most tiles, Tom should use the smallest tiles possible, or 1.1 square feet. Because 320/1.1 is about 290, approximately 290 such tiles can be fit in the area.

a company manufactures and sells novelty Mugs. the manufacturing cost consist of a fixed cost of R8000 and a variable cost of R15 rand per mug. the mugs are sold at R35 each. assume a linear profit function. determine the profit function

Answers

ok so

8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug

profit=R20m-8000
where m=number of mugs sold
(R20 means 20 rand)

f(m)=R20m-8000
