a. A 6 foot high fence casts a 7 foot shadow.
Standing beside the fence is a tree that casts a
31.5 foot shadow. How tall is the tree?

Answers

Answer:

height of tree is 27 ft

Step-by-step explanation:

The corresponding parts of the problem are in proportion

let h be the height of the tree , then

[tex]\frac{6}{h}[/tex] = [tex]\frac{7}{31.5}[/tex] ( cross- multiply )

7h = 189 ( divide both sides by 7 )

h = 27

Height of tree is 27 feet

A father's age now is three times the age that his son was 4 years ago. In 12 years, the father will be twice as old as his son. find their ages now.

Answers

Let’s say son’s age = S
Dad’s age = D
4 years ago, the son was (S-4) and dad now is three times that so D=3(S-4)
Expand that to get D=3S-12

In 12 years, the son will be (S + 12)
Dad will also be (D + 12) and he will be two times the sons age at that point so:
D + 12 = 2(S + 12)
Expand the right side:
D +12 = 2S + 24
Subtract 12 from both sides:
D = 2S + 12
So now D = 2S + 12 AND
D = 3S - 12
Since both equations equal “D”, they must then equal each other:
2S + 12 = 3S - 12
Do some algebra and you get S = 24
Plug this back into EITHER “D=“ equations to find D
D=2(24) +12
D=60

y=-1

Answer:

y= 0.8

Step-by-step explanation

4(3−y) = 6−2(1−3y)

12−4y = 6−2(1−3y)

12−4y = 6−2+6y

12−4y = 4+6y

12 = 4+10y

8 = 10y

0.8 = y

convert into like fraction and arrange in ascending order
a)7/8 and 9/10
b) 1/2, 3/4,6/8

Answers

Answer:

a) 35/40, 36/40

b) 4/8, 6/8, 6/8

Step-by-step explanation:

In order to convert into like fractions, we must find a common denominator for both.

This just means finding the LCM of the existing denominators.

To find the LCM, list the prime factorization of each number, and multiply each factor together the maximum amount of times it appears in one factor.

Then figure out what you need to multiply the existing denominator by to get the common denominator, and multiply that number to the numerator as well.

Note that multiplying a fraction by x/x won't change the value because x/x is equal to 1.

If this sounds confusing- don't worry- it'll become more clear in the work below.

a) 7/8 and 9/10

Start by finding the LCM of 8 and 10

Prime factorization:

8- 2*2*2

10- 2*5

Multiple: 2*2*2*2*5

However, 2 appears in 10 once and 8 three times.

So we can cross out one "2" since the maximum amount of times it appears is three times, not four.

Hence the LCM is 2*2*2*5=40

40 will be the common denominator.

To get to 40 from 8, you need to multiply it by 5.

So we can do:

7/8*5/5=35/40

Repeat with the second fraction.

To get to 40 from 10, you need to multiply it by 4.

So we can do:

9/10*4/4=36/40

36/40>35/40

Therefore, the ascending order would be

35/40, 36/40 or 7/8, 9/10

b) 1/2, 3/4, 6,8

Start by finding the LCM of 2, 4 and 8.

Prime Factorization:

2: 2

4: 2*2

8: 2*2*2

Since 2 appears a maximum of 3 times in one number the LCM is:

2*2*2=8

So our common denominator will be 8.

To get to 8 from 2, you need to multiply it by 4.

1/2*4/4=4/8

To get to 8 from 4, you need to multiply it by 2.

3/4*2/2=6/8

The last fraction is already good.

6/8

Hence, the ascending order would be:

4/8, 6/8, 6/8 or 1/2, 3/4, 6/8

The ratio of fiction books to nonfiction books on the shelf is, 4

What is the ratio?

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Ellie has 20 books on her shelf

Four of these books are nonfiction

The rest are fiction

The ratio of fiction books to nonfiction books on the shelf = ?

The number of fiction books = ?

The number of fiction books = 20 - 4

= 16

Ratio = fiction/nonfiction

= 16/4

= 4

Hence, the ratio is 4
