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)

11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.

11/3 × 3/2. Now all you have to do is multiply

11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

The answer is the last one. (7,-2) (-3,6)

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

A number has many factors including 3 and 8. What other number must also be a factor of the same number?

Answers

Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.

If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."

Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

Practice:

What is the square root of 49?

What is the square root of 100?

What is the square root of 625?

Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.

which number produces an irrational number when added to 1/4

Answers

π is an irrational number when it is added to 0.4 we will get an irrational number

Answer:

A. 0.545454 - 1/4 = 0.295454 yes this is an irrational number

C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number

Step-by-step explanation:

A. 0.545454 - 1/4 = 0.295454 is an irrational number as the closest fraction is shown below at 3 decimal points only

As this can be converted to a fraction 147727 /500000 ≈ 0.295

B. - 4/9 - 1/4 = -0.694444444 is not an irrational number so answer is no

As this can be converted to a fraction -173611111 / 250000000

To write 0.694444444 as a fraction you have to write 0.694444444 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.694444444 = 0.694444444/1 = 6.94444444/10 = 69.4444444/100 = 694.444444/1000 = 6944.44444/10000 = 69444.4444/100000 = 694444.444/1000000 = 6944444.44/10000000 = 69444444.4/100000000 = 694444444/1000000000. Then divide by 470 and we know to use this some as 250000000/531915 = 470

C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number

closest fraction is only 4 significant figures

4017627 / 1250000

=3 and 267627 over 12500003

267627 /1250000

≈3.214 so in closer proof it is an irrational number.

D. sq rt 4 - 1/4 = 1.75 is not an irrational number as this fraction is 7/4 = 1 3/4

If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)

Answers

Answer:

4 hectares

Step-by-step explanation:

The scale factor is:

k = 1/400

Applied 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 hectares
