Michael is 25 years younger than his father. The sum of their ages is 53. What is Michael's age?

Answers

Answer:

Step-by-step explanation:

Answer:

Micheal is 14

Step-by-step explanation:

First you need to minus the 25 from 53 to see how old they both are without the age difference, 53-25=28. Since we are looking at 2 people, we need to divide this number by 2. From this we get 14. Now 14+25=39. So we can prove that our answer is valid. Ergo, Micheal's age is 14.

The price of a flight was increased by 3% to £650. What was the price before the increase? Give your answer to the nearest penny.

Answers

Answer:

£631.07

Step-by-step explanation:

Increasing a value by 3% is the same as taking 103% of it - you have the original price (100%) plus an additional 3% of it. Let's call the original price here p. We're told that after a 3% increase, the price goes up to £650. Put another way: 103% of p is £650. In equation form:

[tex]1.03p=650[/tex]

To solve for p, we can simply divide both sides of our equation by 1.03 to get

[tex]p=650/1.03\approx631.07[/tex]

So our orignal amount, to the nearest penny, was £631.07

Answer:

£631.07

A company makes cars.

The company’s income in 2017 was $500 000 more than the company’s income in 2016
The company’s income in 2017 was 8% more than the company’s income in 2016

Work out the company’s income in 2016?

Answers

Answer:

$6,250,000

Step-by-step explanation:

Let :

2016 income = x

2017 income = x + $500,000

2017 income is 8% more than company's income in 2016

Thus ;

8% of 2016 income = 500000

0.08x = 500,000

x = 6,250,000

Hence, the company's income in 2016 is $6,250,000

need help which one is it
a)x=7
b)x=12
c)x=20

Answers

- you can use the pythagorean theorem for this.

a^2 + b^2 = c^2

12^2 + 16^2 = c^2

144 + 256 = c^2

400 = c^2

- square root this.

c = 20

therefore, x = 20.

so option C.

Answer:

c. X = 20

Step-by-step explanation:

Pythagoras theorem

a² + b² = c²

12² = 144

16² = 256

144 + 256 = 400

√400 = 20

terri is planning to build a garden using the plans below. how much fencing will she need to split the garden on the diagonal? rectangular 40yards by 30yards

Answers

Answer:

Length of the fence is 50 yards.

Step-by-step explanation:

The dimensions of the garden are:

length of the garden = 40 yards

width of the garden = 30 yards

Representing these by the sides of a right angled triangle, the diagonal is the hypotenuse of the triangle. So that applying the Pythagoras theorem, we have:

[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]

Let the diagonal be represented by x, so that;

[tex]x^{2}[/tex] = [tex]40^{2}[/tex] + [tex]30^{2}[/tex]

= 1600 + 900

= 2500

x = [tex]\sqrt{2500}[/tex]

= 50

x = 50 yards

Hence, Terri would need a fence of length 50 yards so as to split the garden on the diagonal.
