Answer: 68

Step-by-step explanation:

if there are 12 inches in a foot and there are 5 feet then that multiplies to 60 inches, simply add the extra 8 and you get 68

Answer:

68 inches.

Step-by-step explanation:

So we know that 1 feet equals to 12 inches.

We just need to multiply 12 by 5 and then plus 8. Which will give us 68.

To do this, we must first put the 8 aside.

Then we multiply, 12x5=60, then we bring back the 8 in.

60+8=68.

So the answer is 68 inches

agen simple math for a middle school student

Answer:

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

Step-by-step explanation:

Let [tex]AB[/tex] a line segment in which [tex]M[/tex] is the midpoint. If both [tex]A[/tex] and [tex]M[/tex] are given, then we determine the location of [tex]B[/tex] from definition of midpoint. That is:

[tex]\frac{1}{2}\cdot \vec A + \frac{1}{2}\cdot \vec B = \vec M[/tex] (Eq. 1)

Where:

[tex]\vec A[/tex], [tex]\vec B[/tex] - Endpoints with respect to origin, dimensionless.

[tex]\vec M[/tex] - Midpoint with respect to origin, dimensionless.

[tex]\vec A + \vec B = 2\cdot \vec M[/tex]

[tex]\vec B = 2\cdot \vec M - \vec A[/tex]

If we know that [tex]A(x, y) = \left(x+6,\frac{1}{3}\cdot y \right)[/tex] and [tex]M(x, y) = (2,-5)[/tex], then the coordinates of [tex]\vec B[/tex] are:

[tex]\vec B = 2\cdot (2,-5)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = (4,-10)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex]

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

Step-by-step explanation:

The trigonometric function gives the ratio of different sides of a triangle. The option that is not an example of trigonometric reciprocals of sine, cosine, and tangent is theorem.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

The trigonometric reciprocal of sine, cosine, and tangent are cosecant, secant, and cotangent, respectively. Therefore, the option that is not an example of trigonometric reciprocals of sine, cosine, and tangent is theorem.

Answer:

29.93° F

____________________

The value of the temperature of 272 Kelvin in Fahrenheit is 29.93° F.

To convert Kelvin to Fahrenheit, enter the supplied value into the below k to f formula. The following are the procedures for converting k to f (Kelvin to Fahrenheit):  °F = (K − 273.15) × 1.8 + 32.

Substitute the given value (in K) in the formula:

Then simplify the expression and find the solution.

Then write the final answer in °F.

To determine the temperature in °F when it is in 272° Kelvin

We need to substitute the value of K as 272 in the K to F formula given above.

⇒ °F = (272 − 273.15) × 1.8 + 32

⇒ °F = -1.15 × 1.8 + 32

⇒ °F = -2.07+ 32

⇒ °F = 29.93°

Therefore, the value of 272 K in Fahrenheit is 29.93° F.

Answer:

(x² - 9)(x² - 1)

Step-by-step explanation:

Using Quadratic trinomials

Factor x⁴ - 10x² + 9

Step 1: Find the two integers whose product of 9 and whose sum of -10

Product

-9 × -1 = 9

Sum

-9 + -1 = -10

Step 2: Use -1 and -9 to complete the factors

x⁴ - 10x² + 9 = (x² - 9)(x² - 1)

Step 3: Use the foil method to check the factors

(x² - 9)(x² - 1) = x⁴ - 1x² - 9x² + 9 = x⁴ - 10x² + 9

Answer:

human skin is thicker than sand , hope this helps

It will take 5 grains of sand to match the thickness of a human's skin.

Comparing numbers in maths defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, Human skin has a thickness of about 5×10⁻³ meter. A grain of sand has a thickness of about 1×10⁻³ meter.

As we can see the that the measurement of sand grain is greater than that of human skin's measurement, the skin is about  5×10⁻³ meter and sand grain is about 1×10⁻³ meter.

We can say,

5×10⁻³ > 1×10⁻³

The human skin's thickness is 5 times greater than the thickness of a sand grain.

Hence, we have to multiply by 5 to measure of the thickness of a sand grain to make it equal to human skin's measurement,

Hence, It will take 5 grains of sand to match the thickness of a human's skin.
