If you have trouble with Division, the way to do it with this equation is:
You know our answer is 20 now, so what is 20/5? (20 divided by 5) This would be 4. This is the Inverse Property of Multiplication.

Answer:

length = 2ft

width = 1 ft

height = 4 ft

Step-by-step explanation:

V = LWH

V = (1/2)y × y × 2y

V = y³ = 8 ft³

y = 2

length = 2ft

width = (1/2)(2 ft) = 1 ft

height = 2(2 ft) = 4 ft

Unitary method:

Unitary method used to find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Given,

27 people will travel for bowling.

As there is only one van.

and in that one van only 12 people can go.

so remaining people will go by car

no. of people that they will go by car

=> 27 - 12 = 15

in one car 5 people can go

no. of cars needed to take people=no. of people/no. of cars

=> 15 / 5 = 3

Therefore 3 cars will be needed.

Cavitation reduces a tree's ability to conduct water due to the formation of air bubbles in water, thereby reducing the hydraulic conductance of the tree.

Cavitation, also known as embolism, is said to occur when the tracheid or vessels of the xylem is being filled with bubbles of air. Cavitation is what is said to occur when air bubbles form in water during transpiration.

The effect of cavitation is the prevention of the upward pull of water, leading to a degradation of hydraulic conductance, such that the xylem water potential is reduced.

Answer:

v = 11

Step-by-step explanation:

(9v - 3) and 84 are a linear pair and sum to 180° , that is

9v - 3 + 84 = 180

9v + 81 = 180 ( subtract 81 from both sides )

9v = 99 ( divide both sides by 9 )

v = 11

Answer:

9 , 16x^2 , 4z and 100y^2 are perfect Squares!

_____________________________________
What are Perfect Squares?

A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer.

3 * 3 = 9
4 * 4 = 16
2 * 2 = 4
50 * 50 = 100

Therefore making those numbers perfect squares.
[NOTE: The numbers that are squared are still perfect squared, just a larger version!]

Answer:

x = 12

AB = 39

AC = 24

Step-by-step explanation:

The sum of AB and BC is equal to the length of AC.

We can write the following equation based on this information :

AB + BC = AB rewrite the equation using given values

4x - 9 + 3x - 12 = 63 add like terms

7x - 21 = 63 add 21 to both sides

7x = 84 divide both sides by 7

x = 12 replace x with 12 in each expression to find the lengths

AB = 4x-9

AB = 4•12 - 9 and

AB = 39

BC = 3x -12

BC = 3•12-12 and

(3x + 4y ≥ 12

In option (c), both inequalities have the same orientation (greater than or equal to) and the same signs (+ and -) in front of the variables (x and y) as the original problem statement. This ensures that the inequalities maintain the same relationship.

Option (a) has one inequality with the opposite orientation (≤) compared to the original problem statement, which would result in an incorrect solution.

The mean is 590.45 and the variance is 0.053.

What is arithmetic mean and variance?

Now,

=> Sum of all the values = 590.1+590.2+590.3+590.4+590.5+590.6+590.7+590.8 = 4723.6

=> Since 8 data values are present,

=> Mean = 4723.6/8 = 590.45

=> 590.1 - 590.45 = -0.35;

=> (-0.35)² = 0.1225

=> 590.2 - 590.45 = -0.25;

=> (-0.25)² = 0.0625

=> 590.3-590.45 = -0.15;

=> (-0.15)² = 0.0225

=> 590.4-590.45 = -0.05;

=> (-0.05)² = 0.0025

=> 590.5-590.45 = 0.05;

=> (0.05)² = 0.0025

=> 590.6-590.45 = 0.15;

=> (0.15)² = 0.0225

=> 590.7-590.45 = 0.25;

=> (0.25)² = 0.0625

=> 590.8-590.45 = 0.35;

Thus, variance = [tex]\frac{(0.1225+0.0625+0.0225+0.0025+0.0025+0.0225+0.0625+0.1225)}{8}[/tex] = 0.42/8 = 0.0525 ≈ 0.053

Answer:

C The metric system is based on powers of 10

Step-by-step explanation:

The square root of 11 and 62 to the nearest tenth is 7.9 and 3.3 .

Given, the numbers are 11 and 62.

we are asked to determine the square root of the given numbers to the nearest tenth.

a. 11

Since the given number is not an even number, hence we can't get a whole number as the square root of 11.

we need to find the number whose square root is nearest to the number 11.

3 × 3= 9

9 is nearer to 11 whereas 4 × 4 = 16 gets greater than 11.

then dividing the number 11 by 3.we get:

√11 = 3.31662479  × 3.316622479

√11 = 3.31662479

√11 = 3.4 (rounding off to the nearest tenth)

b.  62

since we can't get the square root as a whole number so ,

we need to find the number whose square root is nearest to the number 62.

8 × 8 = 64

which gets greater than 62, hence we take 7 × 7 = 49

therefore, √62 = 7.874007874 × 7.874007874

√62 = 7.874007874

√62 = 7.9 (rounding off to the nearest tenth)

hence we get the square root of 11 and 62 as 3.3 and 7.9 respectively.
