Answer:

3 into g into 5 into h

in this we will group the term 3 and 5 together and then the g and h

so the answer will be 3 into 5 into g into h = 15gh

The expression 3 × g × 5 × h is in the simplified form of 15gh.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expression is given below.

⇒ 3 × g × 5 × h

Simplify the expression, then we have

⇒ 3 × g × 5 × h

⇒ 15gh

Answer:

90 cubic inches

Step-by-step explanation:

The formula for a triangular pyramid is 1/3AH. A is the area of the base. H is the height of the pyramid. So to find the area of a right triangle, you would use the formula (a x b)/2. So (10 x18)/2 is 90 inches^2. Now you can fill in the first formula. 1/3(90 x 14), which equals 420 inches^3.

V = 1/3 · area of base · height

V = 1/3 · 18 · 15

V = 6 · 15

V = 90

Answer:

The correct answer is "$159 and $175".

Step-by-step explanation:

The give values are:

Mean,

= $167

Standard deviation,

[tex]\sigma[/tex] = $40

Number of commuters,

n = 100

Now,

⇒ [tex]SE=\frac{\sigma}{\sqrt{n} }[/tex]

On putting the given values, we get

⇒       [tex]=\frac{40}{\sqrt{100} }[/tex]

⇒       [tex]=\frac{40}{10}[/tex]

⇒       [tex]=4[/tex]

By using the 2 SE rule of thumb, we get

= [tex]$(167 - 2\times 4)[/tex]

= [tex]167-8[/tex]

= [tex]159[/tex] ($)

Or,

= [tex](167 + 2\times 4)[/tex]

= [tex]167+8[/tex]

= [tex]175[/tex] ($)

i.e,

$159 and $175

The measure of value of h from the trigonometric relations is h = 11.4 cm

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ΔABC

Now , the value of sides of the right triangle ABC is

AB = 7 cm

AC = h cm

The angle ∠ACB = 38°

Now , from the trigonometric relations , we know

sin θ = opposite / hypotenuse

Substituting the values in the equation , we get

sin θ = 7 / h

sin 38° = 7 / h

Multiply by h on both sides of the equation , we get

h ( sin 38° ) = 7

Divide by sin 38° on both sides , we get

h = 7 / sin 38°

Substitute the value of sin 38° = 0.6157

h = 7 / 0.6157

h = 11.369 cm

Rounding the value to 1 decimal place , we get

The value of h = 11.4 cm

Hence , The measure of value of h is h = 11.4 cm

Answer:

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Step-by-step explanation:

We have to find the formula for the value of 'l'.

So, we will isolate 'l' on one side of the formula.

A = 2lw + 2lh + 2wh

A = 2l(w + h) + 2wh

A - 2wh = 2l(w + h) + 2wh - 2wh

A - 2wh = 2l(w + h)

[tex]\frac{A-2wh}{2(w+h)}=\frac{2l(w+h)}{2(w+h)}[/tex]

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Therefore, formula for 'l' will be,

[tex]\frac{A-2wh}{2(w+h)}=l[/tex]

Step-by-step explanation:

Answer:

1a. Mean pulse rate for A = 60.5

1b. Range for A = 62

2a. Mean pulse rate for B = 73

2b. Range for B = 45

Step-by-step explanation:

1a. Determination of the mean pulse for patient A.

Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69

Mean =?

The mean pulse rate for patient A can be obtained as follow:

Summation of data = 17 + 16 + 70 + 69 + 70 + 75 + 78 + 70 + 71 + 69

Summation of data = 605

Number of data = 10

Mean = summation of data / number of data

Mean = 605 / 10

Mean pulse rate for A = 60.5

1b. Determination of the range for patient A

Data => 17, 16, 70, 69, 70, 75, 78, 70, 71, 69

Range =?

Range = Highest – Lowest

Highest = 78

Lowest = 16

Range = Highest – Lowest

Range = 78 – 16

Range for A = 62

2a. Determination of the mean pulse for patient A.

Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70

Mean =?

The mean pulse rate for patient B can be obtained as follow:

Summation of data = 59 + 92 + 60 + 80 + 71 + 65 + 50 + 88 + 95 + 70

Summation of data = 730

Number of data = 10

Mean = summation of data / number of data

Mean = 730 / 10

Mean pulse rate for B = 73

2b. Determination of the mean pulse for patient B.

Data => 59, 92, 60, 80, 71, 65, 50, 88, 95, 70

Range =?

Range = Highest – Lowest

Highest = 95

Lowest = 50

Range = Highest – Lowest

Range = 95 – 50

Range for B = 45

Answer:

9/27 or 9 to 27

Step-by-step explanation:

Answer: y = 8x -3

Step-by-step explanation:

we know the slope already which is 8.

so the equation is: y = 8x + b

subsutite the x and y to get the value of b

21 = 8(3) + b

21 = 24 + b

b = -3

So the equation is: y = 8x -3

The equation with the given condition is y=8x-3.

Given that, the slope of an equation (m)=8 which is passing through (3, 21).

We need to find an equation for the given condition.

The slope-intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). The equation of the line is the equation that is satisfied by each point that lies on that line.

Now, put m=8 and the coordinates (3, 21) in y=mx+b and simplify.

That is, 21=8×3+b

⇒21=24+b

⇒b=-3

So, the equation is y=8x-3

Therefore, the equation with the given condition is y=8x-3.

Answer:

110 degrees

Step-by-step explanation:

Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.

Answer:

110°

Step-by-step explanation:

Since CDE and FDG are vertical, they are congruent, so:

5x + 15 = 8x - 42

Solve the equation for x

57 = 3x

19 = x

Then solve for one of the angles (I chose CDE but FDG would also work)

5(19)+15

95 + 15

x = 4

Step-by-step explanation:

We have the equation x^3 = 64 and are asked to solve for x.

To solve, we need to isolate x.

x^3 = 64

Cube root both sides by 3 to get x alone :

[tex](x^3)^3 = \sqrt[3]{64}[/tex]

[tex]x = \sqrt[3]{64}[/tex]

Solve for the cube root of 64 :

[tex]\sqrt[3]{64} = 4[/tex]
