The square root of 40 is a rational number if 40 is a perfect square. It is an irrational number if it is not a perfect square. Since 40 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 40?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

15. The floor plan of the basement of a shopping centre is drawn to a scale of 1:400.
If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)
Answer:
4 hectaresStep-by-step explanation:
The scale factor is:
k = 1/400Applied to the area we consider k² as the area is the product of two dimensions.
Find the actual area:
0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectaresPerform the indicated operation and simplify the result.

Find the number that makes the ratio equivalent to 1:5.
6:
Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30

I WILL MARK AS BRAINLIEST! Write and equation that represents the points on the table
Step-by-step explanation:
the general equation :
y = ax +b
2 = 0a+ b => b = 2
4 = -2a + b
4 = -2a +2
2a = 2-4
2a = -2
a = -1
so, y = -x + 2

6(9 + 5x) = 54 +
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

Hi! I'm happy to help!
To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:
18×8=
Now all we have to do is multiply:
18×8=

The height of a bookcase is 1.93 meters. Which expression converts this height to feet? Note: 1 foot is approximately 0.3048 meters and 1 meter is approximately 3.2808 feet.
A
1.93m×(0.3048ft1m)
B
1.93m×(3.2808ft1m)
C
1.93m×(1m0.3048ft)
D
1.93m×(1m3.2808ft)
The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)
To make the conversion of meters to feets , we use dimensional analysis ;
We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :
Recall :
1 meter = 3.2808 feets
Then the height of the bookcase in feets will be :
1.93 meters × 3.2808ft / 1m
Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m

Answer: 47.25
Step-by-step explanation:
the equation for finding the area of a triangle is base times height divided by 2
10.5(9)= 94.5
94.5/2=47.25
Answer:
47.25 sq ft is the area. no idea what you want me to do with the 4% though
Step-by-step explanation:
area for traingles = (base×hight)÷2
so your equation would he (10.5ft×9ft)÷2
10.5×9= 94.5
94.5÷2÷47.25
so the answer is 47.25 ft^2 (or simply sq ft)

Max makes three piles of cards, each consisting of only a Queen and a Jack. Lisa draws one card from each pile. What is the probability that Lisa draws two Queen and a Jack in any order? Make a tree diagram of all the choices
Answer:
3/8
Step-by-step explanation:
The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).
There are only 3 ways in which Lisa can draw two Queens and a Jack:
Queen, Queen, Jack
Queen, Jack, Queen
Jack, Queen, Queen
The probability of each one happening is 1/8
This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:
1/2 x 1/2 x 1/2 = 1/8
This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8
It can be represented on a tree diagram however I am not sure how I can show images/drawings on this
Jinny is selling bracelets for $2.50. So far, she has earned $175.00. She needs to earn more than $230.00 in order to meet her goal.
How many more bracelets, x, does she need to sell in order to reach her goal? Select the inequality that includes the fewest number of bracelets that she can sell and still reach her goal.
Answer: 25
Step-by-step explanation:
she’s earned 175 so far she needs 230. So 230-175=55, so she needs 55 more dollars. 55÷2. 50(price of each bracelet) = 25
