If m∠11 = 118, what is the measure of ∠8?

Answer: 90.718 kilograms

Step-by-step explanation:

The missing information in the square is option(b) x = 4y = 4 √(2) and y = 4.

Given square PQRS, the task is to determine the missing information. A square is a quadrilateral with four equal sides and four equal angles.

The coordinates of the vertices of a square are (x,y), (x+4,y), (x+4,y+4) and (x,y+4).

The missing information, x and y, can be found by solving the equations that represent the sides of the square. We can start by solving for x.

The equation for the side PQ is x + 4y = 2 √(2). Solving this equation for x gives x = 4y - 8 √(2).

Similarly, the equation for the side RS is x + 4y = 4 √(2). Solving this equation for x gives x = 4y = 4 √(2).

Therefore, the missing information is x = 4y = 4 √(2) and y = 4.

The lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon. Rounding this to the nearest order of magnitude gives an answer of (b) 10⁶.

Carbon is one of the most important elements on Earth as it forms the building blocks for life and plays a crucial role in regulating the planet's climate. The carbon cycle is a complex process that involves the exchange of carbon between different reservoirs such as the atmosphere, oceans, biosphere, and lithosphere.

To compare the size of the carbon reservoirs in the biosphere and lithosphere, we can take the ratio of the two reservoirs:

Lithosphere/Biosphere = 100,005,500/560

Simplifying the expression on the right-hand side gives:

Lithosphere/Biosphere = 178,933.93

To convert this ratio to orders of magnitude, we can take the logarithm base 10 of the ratio:

log10(Lithosphere/Biosphere) = log10(178,933.93)

log10(Lithosphere/Biosphere) ≈ 5.25

Therefore, the lithosphere's reservoir of carbon is approximately 10^5.25 or about 177,828 times greater than the biosphere's reservoir of carbon.

Rounding this to the nearest order of magnitude gives an answer of (b) 10⁶.

Step-by-step explanation:

The slope of each line on the given graph is:

Figure 1: -1/4

Figure 2: 0

Figure 3: -4

Figure 4: 4

The slope (m) of a linear relationship is calculated as rise/run = change in y / change in x.

Figure 1:

Slope (m) = change in y / change in x = -1/4 (the line declines, so the slope will be negative).

Figure 2:

Slope (m) = 0 (this is because there is no rise but run), thus, the slope of any horizontal line is always 0.)

Figure 3:

Slope (m) = change in y / change in x = -4/1 = -4 (the line declines, so the slope will be negative).

Figure 4:

Slope (m) = change in y / change in x = 4/1 = 4 (the line rises, so the slope will be positive).

∫ 8 (x+a)(x+b) dx = (8/3)x³ + 4x²(a+b) + 8x(ab) + c

The antiderivative of 8 (x+a)(x+b) with respect to x is (8/3)x³ + 4x²(a+b) + 8x(ab) + c.

To evaluate the integral, we can use the distributive property to expand the expression in the integrand:

8 (x+a)(x+b) dx = 8(x² + (a+b)x + ab) dx

We can then integrate each term separately using the power rule of integration:

∫ 8(x² + (a+b)x + ab) dx = (8/3)x³ + 4(a+b)x² + 8abx + c

We can simplify this result by factoring out the constant 8/3 from the first term and using the distributive property to factor out the common factor of 4x from the last three terms:

(8/3)x³ + 4(a+b)x² + 8abx + c = (8/3)x³ + 4x²(a+b) + 8x(ab) + c

We can check our answer by taking the derivative of the result to see if it matches the original integrand. The derivative of (8/3)x³ is 8x², the derivative of 4x²(a+b) is 8x(a+b), the derivative of 8x(ab) is 8ab, and the derivative of the constant c is 0. Adding these terms together, we get the original integrand of 8(x+a)(x+b) dx, so our answer is correct.

70 °C is equal to 158 °F.

A temperature unit developed from the SI (International System of Units) is the Celsius (symbol: °C).

Prior to the adoption of the metric system, the Fahrenheit (symbol: °F) was a commonly used measurement of temperature.

To convert a temperature from Celsius (°C) to Fahrenheit (°F),

We can use the following formula:

°F = (°C x 1.8) + 32

Where

°F is the temperature in Fahrenheit

°C is the temperature in Celsius.

Substituting 70 for °C,

We get:

°F = (70 x 1.8) + 32

Simplifying the expression:

°F = 126 + 32

°F = 158

Therefore, 70 degrees Celsius is equal to nearly 158 degrees Fahrenheit.

The figure W has one Rotational symmetries. This can be observed by rotating the figure by 0 or 180 degrees and noting that the shape remains unchanged. so the correct option is (b).

The letter W has one vertical line of symmetry that divides it into two identical halves. However, it does not have any rotational symmetry of order 2 or higher because there is no way to rotate the letter by a certain angle and have it look the same as before the rotation. Therefore, the answer is (b) 1, as W has only one line of symmetry and no rotational symmetry of order 2 or higher.

The number of adults and the number of children who used the swimming pool is 102 and 304 respectively.

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations which on solving gives the intersecting point of all the solutions.

Let x be the number of adults and y be the number of children who swam on that day.

Total of 406 people swam in the swimming pool that day.

Number of adults + number of children = 406

x + y = 406

Assuming the receipts for admission totaled $609.5.

Cost per child is $1.25 and cost per adult is $2.25.

Cost for x adults and y children is $609.5.

2.25x + 1.25y = 609.5

We have to solve,

x + y = 406

2.25x + 1.25y = 609.5

Multiplying the first equation with 2.25,

2.25x + 2.25y = 913.5

Subtracting 2.25x + 1.25y = 609.5 from 2.25x + 2.25y = 913.5,

y = 304

x = 406 - 304 = 102

The actual length of the living area is 134.4 feet if the length in the scale drawing is 16.8 in the scale.

To determine the actual length of the living space from a scale drawing, we need to use the scale factor, which is the ratio of the length in the drawing to the actual length. If the length in the scale drawing is 16.8 inches and the scale is given as a ratio of 1 inch in the drawing to 8 feet in actual size, we can set up a proportion:

1 inch (drawing) / 8 feet (actual)

= 16.8 inches (drawing) / x (actual)

We can cross-multiply and simplify to find x's value:

1 inch × x = 8 feet × 16.8 inches

x = (8 feet × 16.8 inches) / 1 inch

x = 134.4 feet.

Therefore, the actual length of the living space is 134.4 feet.

Answer:

12,370.34 square yards

Step-by-step explanation:

The shaded area between the two circles is known as an annulus.

This can be computed by the formula
A₂ - A₁

where
A₁ = area of the inner (smaller circle)
A₂ = area of the outer (larger circle)

We also have
A₁  = π · r₁²
A₂ = π · r₂²

where
r₁ = radius of inner circle
r₂ = radius of outer circle

So

Area of shaded region (area of annulus)
= π · r₂² - π · r₁²
= π (r₂² - r₁²)

We are given r₁ = 25.9 yds

Outer circle has a radius r₂  = inner circle radius + annulus width
r₂ = 25.9 + 42
r₂ = 67.9 yds

Area of the shaded region
= π (67.9² - 25.9²)

= π (4,610.41 - 670.81)

= π  x 3,939.6

=  12,370.344  square yards (using π = 3.14)
=  12,370.34 square yards (rounded to nearest hundredth)

Systolic and diastolic blood pressure can be used in a formula to calculate mean arterial pressure, or it can be measured directly. A blood pressure cuff provides the information required to estimate the mean pressure in the least invasive way possible.

A comparable method is to measure blood pressure with an oscillometric device, which computes the systolic and diastolic values using only a cuff and a microprocessor.
