Step-by-step explanation:

The pool is 10 feet long and 4 feet deep. This means the pool has a volume of 40 cubic feet (10 feet x 4 feet x 1 foot). To calculate the width of the pool, divide the total volume (40) by the length (10) to get 4 feet. Therefore, the width of the pool is 4 feet.

The average speed of whole trip was 6.7 mile per hour.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Given that, the total distance =6+6=12 miles and total time

=58+49= 107 minutes

So, number of hours = 107/60

= 1.8 hours

Now, the average speed = 12/1.8

= 6.7 mile per hour

Therefore, the average speed is 6.7 mile per hour.

21 is 18.75% of 112. Percentage is widely used to represent a difference or contrast between two numbers.

A percentage is a way to express a number as a fraction of 100. It is often used to express a change or a comparison between two numbers. The symbol for percentage is %, and it represents the fraction of 100. For example, 50% means 50 out of 100, or 1/2.

Percentages are often used to represent increases or decreases in a quantity, as well as ratios and proportions. For example, if the price of a product increases by 20%, it means the new price is 120% of the original price, or 1.2 times the original price. If a student scores 80% on a test, it means they answered 80 out of 100 questions correctly.

Percentages can be easily converted to decimals or fractions by dividing by 100. For example, 50% can be written as 0.5 as a decimal or 1/2 as a fraction. Similarly, 75% can be written as 0.75 as a decimal or 3/4 as a fraction.

To find what percent 21 is of 112, we can use the formula:

Percent = (Part ÷ Whole) x 100

In this case, the part is 21 and the whole is 112, so:

Percent = (21 ÷ 112) x 100

Percent = 0.1875 x 100

Percent = 18.75

Therefore, 21 is 18.75% of 112.

Step-by-step explanation:

=01000101

is the answer

The binary value of the given expression is 111101.

To multiply binary numbers, we use the same process as with decimal numbers, but using only 0s and 1s. We can use the distributive property of multiplication to break down the problem into simpler multiplication and addition operations.

First, we multiply 1101 by 101:

                                  1101

                                x  101

                                  -----

                                  1101

                                  1101

                                ------

                              111001

Next, we add 100 to the result:

                              111001

                            +    100

                               -------

                              111101

The decimal value of 111101 is given by,

                              (111101)₂ = (61)₁₀

Therefore, the product of 1101 and 101, plus 100, is 111101 in binary.

According to the question,  10% of all college students are foreign students who also smoke and it is also known that 40% of all foreign college students smoke.

We use the conditional probability formula to solve this question.

Let foreign students be denoted as F

Let students smoking be denoted as S

We know that 10% of all college students are foreign students who also smoke this means

P(F ∩ S) = 0.1

Step-by-step explanation:

3/4 (1/6 x +16) = 3/7 (4 3/8 - 21)      expand L side and compute R side

3/24 x + 12 =  - 7.125        Subtract 12 from both sides of the equation

3/24 x = -19.125             Multiply both sides by 24/2

x = -153

THIS EQUATION DOES SHOW x = -153

PERHAPS you MEANT this :

3/4 (1/(6x) +16) = 3/7 (4 3/8 - 21)       Expand L side  and compute R side

3/(24x) + 12 = - 7.125       subtract 12 from both sides

3/(24x) = -19.125      re-arrange

3 / (-19.125)    = 24 x      divide both sides by 24

but in this expression

f (x ) = 10 * x²

g (x) = 3 * 2raise to the power x

priya's conclusion is incorrect because in the other expression the power of x is increasing exponentially so eventually g(x) will be greater than f(x)

Answer:

The surface area of the toy that is yellow is 847.8 inches², to the nearest tenth.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

A square pyramid is a three dimensional object with one square base and 4 four triangular lateral faces.

Total surface area of the pyramid = Area of the base + 4(area of triangular face)

Base length = 24 inches

Base area = 24² = 576 inches²

Height of the pyramid = 20 inches

The slant height, l of the triangle can be found as,

l = [tex]\sqrt{(\frac{a}{2} )^2+h^2}[/tex], where a is the length of the base and h is the height.

l = [tex]\sqrt{12^2+20^2}[/tex]

 = √544

 = √(34 × 16)

 = 4√34 inches

Area of 4 triangular faces = 4 ([tex]\frac{1}{2}[/tex] × 24 × 4√34)

                                           = 2 × 24 × 4√34

                                           = 192√34 inches²

Total surface area = 192√34 inches² + 576 inches²

                              = (192√34 + 576) inches²

                              = 1695.5428 inches²

Surface area of toy that is yellow = 1695.5 / 2 = 847.8 inches², to the nearest tenth.

Hence the surface area of the yellow part of toy is 847.8 inches², to the nearest tenth.

The cost of nails can be represented as 12.99n, and the cost of screws can be represented as 14.99s.

The cost of buying nails and screws can be represented by a system of inequalities where "n" represents the number of boxes of nails and "s" represents the number of boxes of screws.

The cost of one box of nails is $12.99 and the cost of one box of screws is $14.99. Hence, the cost of "n" boxes of nails is represented by 12.99n and the cost of "s" boxes of screws is represented by 14.99s. The carpenter has a budget of $60 and can spend no more than that.

Therefore, the combined cost of buying nails and screws must be less than or equal to $60. This requirement can be represented by the inequality 12.99n + 14.99s <= 60.

To make the calculation easier, we can also express the inequality as n + s <= 4.62, where 4.62 is obtained by dividing $60 by $12.99. This system of inequalities represents the carpenter's budget constraint and helps to determine the number of boxes of nails and screws that can be purchased within the budget.

Step-by-step explanation:

any point and its coordinates is an ordered pair of (x, y).

in other words, we get the x value used for the function and the resulting y value.

if the equation is true for such a pair, then the point is on the line. if it is false, then not.

y = (-5/4)x + 5

(4, 0)

0 = (-5/4)×4 + 5 = -5 + 5 = 0

true.

(0, 5)

5 = (-5/4)×0 + 5 = 0 + 5 = 5

true.

y + 5 = (-5/4)(x - 4)

(4, 0)

0 + 5 = (-5/4)(4 - 4)

5 = (-5/4)×0 = 0

false.

so, II is not containing (4, 0).

therefore, only I is contains both points.

Therefore , the solution of the given problem of inequality comes out to be x ≤ 48.

A relationship or collection of numbers without the equal sign is known as a mathematical inequality. Equilibrium is typically followed by equity. Inequality happens when two factors are not equal. Differences exist between variable equity and inequality. Because the digits are not identical or similar, the most typical symbol was selected (). Any difference, regardless of how small or large, can be used to evaluate values.

Here,

If each side of the frame can be at most 12 inches long, then the perimeter of the frame can be at most 4 x 12 = 48 inches.

Answer: 0.75

Step-by-step explanation:

With a volume of 700 cubic feet and a height of 9 feet , the radius of cylinder is 3.49 feet after rounding to nearest hundredth.

To find the radius of a right cylinder, you need to know its volume and height. The formula for the volume of a cylinder is given by:

V = πr^2h

Where r is the radius, h is the height, and π is approximately equal to 3.14.

Given that the volume is 700 cubic feet and the height is 9 feet, we can substitute these values into the formula:

700 = πr^2 * 9

Dividing both sides by π * 9:

700 / (π * 9) = r^2

Taking the square root of both sides:

√(700 / (π * 9)) = r

Using a calculator and rounding to the nearest hundredth, we find that:

r ≈ 3.49
