Answer:
64
Step-by-step explanation:
Given :
h α 1 / sqrtk
h = k/sqrt(d)
Obtain the value of k, when. d = 4 and h = 20
20 = k / sqrt(4)
20 = k / 2
20 * 2 = k
k = 40
Therefore, the value of d when h = 5
h = k/sqrt(d)
5 = 40 / sqrt(d)
Square both sides
25 = 1600/d
25d = 1600
d = 1600 / 25
d = 64
d = 64

Ethen is ‘x’ years old. Raj is 8 years older than Ethen. Find the sum of their ages in 6 years time.
Answers
Answer:
The sum of their ages in 6 years time is (2x+20) years.
Step-by-step explanation:
Given that,
Ethen is ‘x’ years old.
Raj is 8 years older than Ethen.
Raj's age = (x+8) years
We need to find the sum of their in 6 years.
After 6 years,
Ethen's age = (x+6) years
Raj's age = (x+8)+6
= (x+14) years
Sum of ages = (x+6) + (x+14)
= 2x+20
Hence, the required answer is (2x+20) years.
If 400,000 tourists contribute $67 million to a local economy, how much would 600,000 tourists contribute?
Answers
Answer:
[tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
Step-by-step explanation:
Given that,
400,000 tourists contribute $67 million to the local economy.
We need to find how much would 600,000 tourists contribute.
400,000 tourists = $67 million
1 tourist = [tex](\dfrac{67}{400,000 })\ \text{million}[/tex]
So, 600,000 tourists contribution is :
[tex]600000\ \text{tourists}=(\dfrac{67}{400,000 })\times 600000\ \text{million}\\\\=100.5\ \text{million}[/tex]
Hence, [tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.

Which of the expressions below has a 1 in the tenths place of the product? Select all that apply. A) 18.3 x 7 B) 6.5 x 4.31 C) 8.54 x 2.3 D) 5.4 x 2.8
Answers
Answer: A) 18.3 x 7 and D) 5.4 x 2.8
Step-by-step explanation:
A) 18.3 x 7 = 128.10
We can infer that 1 is in the tenths place.
B) 6.5 x 4.31 = 28.015
We can infer that 1 is not in the tenths place but rather the hundredths place.
C) 8.54 x 2.3 = 19.642
We can infer that 1 is not in the tenths place.
D) 5.4 x 2.8 = 15.12
We can infer that 1 is in the tenths place.

A rectangle has a perimeter of 238 meters and a length of 67 meters what is the area of the rectangle
Answers
Answer:
3,484 meters squared
Step-by-step explanation:
Since it’s a rectangle, opposite sides are the same length. This means 2 of the sides are 67 meters each, since the length of the rectangle is 67 meters. To find the width, add the 2 sides together that we know the length of (in this case it would be 67+67) and subtract it from the total perimeter (238-[67+67]). Take the result (104) and divide it by 2 (104÷2=52). Now that we know the width is 52 meters, you can find the area by multiplying the length times the width (67*52=3,484 meters)
Remember that the perimeter is the total length around the outside of the shape, and the area is the space inside of the shape

The total price for a computer and a
printer was $1039. If the computer
cost $750, how much did the printer
cost?
Answers
Answer:
$289
Step-by-step explanation:
If you know the cost of one of the two items, you can subtract that item from the total in order to find the price of the second item
So: total price - computer price = printer cost
So: $1039- $750 = $289
The printer is $289
