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

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:

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]

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:

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:

y = -(5/2)x + 3 is a line perpendicular to y = (2/5)x + 2. This line is also perpendicular to y = (2/5)x + 9 because it has the same slope.

Step-by-step explanation:

A) So the line you are given is written in slope intercept form y = mx + b meaning that the slope of the line is  m = 2/5 and the intercept  b = 9 (so the line hits the y axis at 0,9). A line that is parallel has to have the same  slope so we know our m is the same. So we have y = (2/5)x + b. We need b. It passes (0, 2) since the x coordinate is 0 you know the y intercept is 2 but you can verify this using the point slope formula:

y - y1 = m(x - x1) plug in values

y - 2 = (2/5)(x - 0) now simplify

y - 2 = (2.5)x  last solve

y = (2/5)x + 2 see how when the x coordinate is 0 you can automatically use the point slope intercept formula? Neato!

B) Now we want a line perpendicular to y = (2/5)x + 2 and that passes through 0,3. What are the properties of a line perpendicular to a line of the form y = mx + b and passes through (0, 3)?  We know that the slope of this new line will be the reciprocal and have the opposite sign of m. So the new slope we will call it mnew = -(1/m) so plug in for m and you get mnew = -(1/[2/5]) if you simplify you get that the mnew = -(5/2). So we have half of our equation for the perpendicular: y = -(5/2)x + b. If you look at (0, 3) you see that the y intercept is 3 so b = 3. So:

The equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, we need to find the equation of a line passing through the point (3, 5) and is parallel to y = 2x-6,

Comparing the given equation with the general equation of line y = mx+c

m = 2 (the slope)

We know that the two parallel lines have equal slope.

Therefore, the required equation is =

y = 2x+c

To find the value of c, put x = 3 and y = 5,

5 = 2(3) + c

c = -1

Therefore,

The required equation is =

y = 2x-1

Hence, the equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

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.

n = 100

Now,
