Answer:

The student is wrong, the total area = 16 ft² + 20 ft²

Step-by-step explanation:

The figure can be consists of :

1) A square of side length of 4 ft

2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)

So,

The area of the square = 4 * 4 = 16 ft²

The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²

So ,the total area = 16 + 20 = 36 ft²

So,

The student is distracted.

he have found the area of total rectangle of length of 8 ft and width of 6 ft instead of the area of the trapezoid.

So, the student is wrong

Answer:

17.5

Step-by-step explanation:

35% = 0.35 in decimal form.

(Think about: 1 = 100%)

To find 35% of 50, we simply multiply.

0.35 × 50 = 17.5

35% of 50 is 17.5

Answer:

x^2+36 or x2 + 36 = 0

Step-by-step explanation:

Answer:

x> 6 twice

Step-by-step explanation:

x^2+36>12x

x² + 36 > 12x

Collect like terms

x² - 12x + 36 > 0

Solve quadratically using factorisation method by finding two factors of 36 that when added gives -12, the coefficient of x.

Factors = -6 and -6 which both add up to -12

Rewrite equation

x² - 6x - 6x +36> 0

Factorise by taking out the common factor

x ( x - 6) -6( x - 6) > 0

(x -6)(x - 6) > 0

x - 6 > 0 or x -6 > 0

Add 6 to both sides

x -6+6> 0+6 or x-6+6>0+6

x > 6  or x> 6

x> 6 twice

Answer:

(-1,-5)

Step-by-step explanation:

Answer:

slope = - 4, y- intercept = - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x - 9 ← is in slope- intercept form

with slope m = - 4 and y- intercept c = - 9

Answer:

y= 4/5x +2/5

Step-by-step explanation:

When finding slope, use the format y-y1/x-x1. Plug in your coordinates to get this: 8-4/2--3. 8-4 equals 4, and 2--3 equals 5. So, your slope would be 4/5. Next, make your equation like this: y=4/5x+b. Next, plug in one of your ordered pairs into the equation. It doesn't matter which one you use. I'm going to use the second pair, so it would look like this: 8=4/5(2)+b. Multiply 4/5 by 2 to get 8/5. This is what you should have: 2=8/5+b. Subtract 8/5 from both sides to get your y-intercept of 2/5. Go back to your original equation and plug in 2/5 to b. This is your final equation: y= 4/5x +2/5. Hope this helped!

Answer:

Starting from the definitions of each concept, we have to:

Divider = number you are dividing

Quotient = result of division

Therefore, for them to be the same number is half of the sum they tell us, which means that 8/2 = 4, then the quotient is 4 and the divisor is 4 too, and the dividend 4 * 4 = 16

The division would be:

16/4 = 4

Thus fulfilling the premise of the problem.

The domain of the function h(x) = √(x-10) is all real numbers x that are greater than or equal to 10, because we cannot take the square root of a negative number under the real number system.

In mathematics, the domain of a function is the set of all the possible input values (usually denoted as x) that would lead to a real and defined output. As for the function h(x)=√(x-10), we have a square root operation involved. We know that under the real number system, we cannot take the square root of a negative number.

Hence, for the function h(x)=√(x-10) to be real and defined, (x-10) must be greater than or equal to 0. That is, x-10 ≥ 0. Solving for x, we get x ≥ 10.

Therefore, the domain of the function h(x) = √(x-10) is x≥10. That is, h(x) is defined for all real numbers x that are greater than or equal to 10.

Without additional context or details about how JK, JL, and JM are related, it's impossible to accurately calculate or deduce the value of JM. Further clarification or more information about the scenario or the mathematical or geometric principles involved is needed for a precise answer.

The question provided does not seem to present enough context or connection to standard mathematical operations or geometric principles that would enable a straightforward calculation or deduction of the value of JM. Without additional information about the relationship between JK, JL, and JM (such as whether they are sides of a triangle, or represent values in a given mathematical formula), or without a clear mathematical or geometric context, it's impossible to accurately determine the value of JM.

Generally, in mathematics, when calculating distances or values based on given lengths, one needs to apply specific formulas or theorems (such as the Pythagorean theorem in the context of right-angled triangles, or vector addition in the context of physics problems). Unfortunately, the given data lacks the necessary context to apply such principles.

For a precise and accurate answer, I recommend clarifying the problem's context or providing more details about the scenario in which JK, JL, and JM are related.

-Final answer:

To find JM in a triangle with known side lengths JK = 7 and JL = 12, we use the Triangle Inequality Theorem to determine that JM must be less than 19.

Explanation:

To find JM, we can use the fact that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side (Triangle Inequality Theorem).

JK + JL > JM

7 + 12 > JM

19 > JM

Therefore, JM must be less than 19 but more than the absolute difference of JK and JL, so JM < 19.

Answer:

Actual width = 5 feet.

Step-by-step explanation:

The ratio of 1.2 to 1  equals the ratio of length to width.

1.2 / 1  = 6 / w  where w is the actual width.

1.2w = 6

w = 6/1.2

w = 5.

Answer:

g = 6

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 2

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (10, g) and (x₂, y₂ ) = (9, 4)

m = [tex]\frac{4-g}{9-10}[/tex] = [tex]\frac{4-g}{-1}[/tex] = 2 ( multiply both sides by - 1 )

4 - g = - 2 ( subtract 4 from both sides )

- g = - 6 ( multiply both sides by - 1 )

g = 6

The value of x in the right-angle triangle is 2√3.

A triangle is also known as a right-angled triangle if one of its three angles is 90 degrees. A right-angled triangle's three interior angles all add-up to 180 degrees, thus if one angle is always 90 degrees, the other two must also always add up to 90 degrees.

In the given figure,

BC = 6cm

DC = 6/2 = 3cm

By formula of angle on a straight line,

∠EDB = 180° - (90°+60°)

= 180° - 150°

= 30°.

From right-angled triangle ADC,

AD² = 5² -3² (As per Pythagoras theorem)

= 25 - 9

= 16.

So, AD = √16

= 4cm.

From ∠AEC. let AS = x.

w/Sin60° = 4/Sin90°

We know,

Sin90° = 1

Sin60° = √3/2

⇒ x = (4 × Sin60°)/Sin90°

⇒ x = 4 × √3/2

⇒ x = 2√3

The frequency of red light is 4 x 10¹⁴ Hz. The correct answer is option D.

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

The given that when the frequency of an electromagnetic wave is 400,000,000,000,000 Hz, it results in red light.

The choices given are in scientific notation form, where the coefficient is multiplied by 10 raised to a certain power of 10.

To convert 400,000,000,000,000 Hz into scientific notation, we need to move the decimal point 14 places to the left to obtain a coefficient between 1 and 10.

This gives us 4.0 as the coefficient, and since we moved the decimal point 14 places to the left, the power of 10 is -14.

Therefore, the frequency of red light is 4 x 10¹⁴ Hz.

Answer:

It's 63.75 since I looked it up.

The area of the (ring) - the shaded region is 75.36 in²

Solution:

The value of π = 3.14

Radius of the inner circle = 5 in

Area of the inner circle = πr²

                                       = π × 5²

Area of the inner circle = 25π

Radius of the outer circle = (5 + 2) = 7 in

Area of the outer circle = πr²

                                       = π × 7²

Area of the outer circle = 49π

Area of the shaded ring = Area of the outer circle – Area of the inner circle

                                        = 49π – 25π

                                        = 24π

                                        = 24 × 3.14

                                        = 75.36 in²

Thanks for the question!

When rounded to two decimal places, 89 divided by 3 is approximately 29.67.

To calculate 89 divided by 3 in decimal form, we perform the division operation:

89 ÷ 3 ≈ 29.666666...

The division result is a repeating decimal with the digit 6 repeating infinitely. However, since you asked for the answer in decimal form, rounded to a certain number of decimal places, we can round the result to a reasonable precision.

Step-by-step explanation:

in order to find  the volume ,in cubic meter ,of a cylinder with a height of 3 meters and a base radius of 4 meters ,to the nearest theths place wee apply the formular for finding the volume of a cylinder which is πr²h

v =  πr²h

given that

height = 3meters

radius = 4meters

volume=?

going by the formulae v= πr²h

v = π × (4)² × 3

v = π × 16 ×3

v= 48πm³

note the value of π = 22/7

v = 48 × 22/7

v = 1056/7

v= 150.87m³
