Lila thought of a whole number and added the next whole number to it. What was the original number she thought of if the sum was 22?

Answers

Answer:

10

Step-by-step explanation:

Let the original whole number be x and the next whole number be x+2

If Lila added both number and the sum was 22, then:

x + (x+2) = 22

x+x+2 = 22

2x +2 = 22

2x = 22-2

2x = 20

divide both sides by 2

2x/2 = 20/2

x = 10

Hence the original number she thought of was 10

Henry predicted whether he got answers right or wrong in his 50 question exam. He identified the 31 questions he thought he got right. It turns out that Henry got 6 questions wrong that he thought he got correct and he only got 12 of the questions wrong he had predicted. What is the percentage accuracy he had with predicting his scores?

Answers

Answer:

74%

Step-by-step explanation:

Given that :

Total number of questions = 50

Total correct prediction :

Correct and right prediction = ( 31 - 6) = 25

Correct wrong prediction = 12

Total correct predictions = (25 + 12) = 37

Percentage prediction accuracy :

(Total correct prediction / total questions) * 100%

(37/ 50) * 100%

0.74 * 100%

Two families go to the theatre the Smith family of three adults and four children pay £67 the Jones family of five adults and six children pay £106 work out the cost of an adult ticket and the cost of a child ticket in your working at a stand for an adult ticket and C stand for child ticket

Answers

Answer: adult = $11

Child = $8.5

Step-by-step explanation:

Let the cost of an adult ticket be a

Let the cost of child ticket be c.

From the question,

3a + 4c = $67 ....... i

5a + 6c = $106 ...... ii

Multiply equation I by 5

Multiply equation ii by 3

15a + 20c = $335

- 15a + 18c = $318

2c = $17

C = $17/2 = $8.5

Put the value of c into

3a + 4c = $67

3a + 4($8.5) = $67

3a + $34 = $67

3a = $67 - $34

3a = $33

a = $11

Cost of adult ticket = $11

cost of child ticket = $8.5

The design that should  give Shanika what she wants is the radius of 90 cm.

Calculation of the design:

Since The table has a radius of 40 centimeters and height of 60 centimeters. She wants the tablecloth to hang an even 10 centimeters above ground.

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the number be represented as A

Now , the value of A is

A = 53.864

Now , on rounding the number A to the nearest , we get

Step 1 :

If we round the number to the nearest integer, the number is 54

Step 2 :

If we round the number to the nearest tenth, the number is 53.9

Step 3 :

If we round the number to the nearest hundredth, the number is 53.86

So , the number 53.87 is not true

Step 4 :

If we round to the nearest tens, the number is 50

Hence , the only incorrect rounding is 53.87
