Answer:

negative; -1/4

Step-by-step explanation:

Answer: 4

Step-by-step explanation:

The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:

x = k / ✓y

When x = 12, y = 9

We have to calculate the constant of proportionality, k which will be:

12 = k / ✓9

12 = k / 3

k = 12 × 3

k = 36

To find the value of x when y = 81 will be:

x = k / ✓y

x = 36 / ✓81

x = 36 / 9

x = 4

Therefore, x = 4 when y = 81.

Answer:

x = √10

Step-by-step explanation:

3x² = 30

Divide both sides by 3.

x² = 10

x = √10

Answer:

C. 75

Step-by-step explanation:

First, list the multiples of each numbers and stop when you reach the least common multiple (the smallest number the numbers can multiply up to):

5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 . . .

25: 25, 50, 75 . . .

15: 15, 30, 45, 60, 75 . . .

5 times 15 is 75, 25 times 3 is 75, and 15 times 5 is 75. Their LCM is 75.

Answer:

400

Step-by-step explanation:

Volume=⅓*B*h

B=10×10=100

Bh=100×12=1200

then divide by

1200÷3=4

The volume of a pyramid with a square base is 400 cm³.

A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

We have,

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

Now,

Height = 12 cm

Base area = 10² = 100 cm²

Now,

Volume.

= 1/3 x 100 x 12

= 400 cm³

Thus,

The volume of a pyramid with a square base is 400 cm³.

Answer:

  A.  82.9 yds

Step-by-step explanation:

The missing leg of the right triangle can be found from ...

  w²+ l² = d²

  w² + 125² = 150²

  w² = 150² -125² = 22500 -15625 = 6875

  w = √6875 ≈ 82.9

The width of the field is about 82.9 yards.

Answer:

Median is 18

Step-by-step explanation:

Firstly you have to fine y by using your mean

Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15

22+18+2y+1+10+20 over 5 =15

71+y over 5 =15

Cross multiple

71+y=75

y=4

22,18,9,10, 20

Rearrange

9,10,18,20,22

The median is 18

Answer:

Pink Trapezium = 30   as 30 x 1 = 30

Purple Diamond = 2    as 2 x 2 = 4

Green Moon = 7.5     as it shares the line with 4 it goes 4 x 7.5 = 30

The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.

When we show the values see below. We have 30 also for the second line so both lines are equivalent

Step-by-step explanation:

I would multiply as addition is just too easy.

Pink Trapezium is 1 x 30 = 30  = 30/1 = 30 value

Purple diamond = 2 x 2 = 4  = 4/2 = 2 value

Green Moon is 30/4 = 7.5 value

Answer:

1/3 x 1/3 = ?

3 x 3 = ?

Step-by-step explanation:

3 x 3 = 9 yesyes

1/3 x 1/3 = 1/9

now we add, right? 9/1 ( same as 9 ) + 1/9 = ?

does it want it in fraction, decimal, or whole?

Answer:

9 1/9 is the answer

Step-by-step explanation:

1/3 to the power of 2 becomes 1/9

3 to the power of 2 becomes 9

[tex]\frac{1}{9} + 9[/tex]

whole numbers always go over a 1

[tex]\frac{1}{9} + \frac{9}{1}[/tex]

make 9/1 have the same denominator as 1/9 by multiplying the top and bottom with 9

[tex]\frac{1}{9} + \frac{81}{9}[/tex] [tex]= \frac{82}{9}[/tex]

the simplify 82/9

[tex]\frac{82}{9} = 9\frac{1}{9}[/tex]
