Answer:

The price for a 10 pack of erasers would cost $4.09

Step-by-step explanation:

1.47 ÷ 3 = 0.49

0.49 × 10 = 4.9

Answer:

$4.9

Step-by-step explanation:

[ Unitary method]

3 pack of erasers = $1.47

1 pack = $1.47 / 3 = $ 0.49

10 pack = $ 0.49 x 10 = $4.9

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:

Please check the explanation.

Step-by-step explanation:

Part 1)

5x + 9y, when x=8, y=11

substituting x=8, y=11 in 5x + 9

5x + 9y = 5(8) + 9(11)

            = 40 + 99

            = 139

Part 2)

a³ –c + b, when a=3, b=6, c=8

substituting a=3, b=6, c=8 in a³ –c + b

a³ –c + b = (3)³ - 8 + 6

               = 27 - 2

               = 25

Part 3)

4(g –h) +10, when g=12, h=7

substituting g=12, h=7 in 4(g –h) +10

4(g –h) +10 = 4(12 - 7) + 10

                  = 4(5) + 10

                  = 20 + 10

                  = 30

Part 4)

k³ –4j +12, when k=8, j=2

substituting k=8, j=2 in k³ –4j +12

k³ –4j +12 = (8)³ - 4(2) + 12

                 = 512 - 8 + 12

                 = 516

Step-by-step explanation:

When you graph the equation, it hits every point as seen below.

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

110

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.

The ∠DCO will be 2·x, 69° is the sum of  ∠DCO and x° is x = 23°

A curving line makes up the form of a circle. It is spherical, and every point along the curving line is equally spaced first from the center. Due to its multiple nature, this form is flat.

Points on the circle is A, B, C, and D

Straight lines  present are AOBE and DCE

Segment CO = Segment CE

∠AOD = 69°

∠CEO = x°

∠OCD = ∠ODC as this is an isosceles triangle

an exterior angle of a triangle can be determined as

69° = ∠x° + ∠ODC

Because of the Angle sum property of a triangle

∠DOC = 180 - 2×∠ODC

Angles added together on a linear fashion are supplementary.

180 - 2×∠ODC + x° + 69° = 180°

x° + 69° - 2×∠ODC = 0

A triangle's exterior angle is equal to the product of its diagonal internal angles

∠ODC = 2·x°

69° = x° + ∠ODC = x° + 2·x° = 3·x°

69° = 3·x°

x = 69° ÷ 3

x = 23°

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:

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

Given:

A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport.

The total charge is AED 135.

To find:

How far, in kilometers, is the trip to the airport?

Solution:

Let x km be the trip to the airport.

A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. So, total changes for x km trip is

[tex]T=10+250x[/tex]

The total charge is AED 135.

[tex]10+250x=135[/tex]

[tex]250x=135-10[/tex]

[tex]250x=125[/tex]

Divide both sides by 250.

[tex]x=\dfrac{125}{250}[/tex]

[tex]x=\dfrac{1}{2}[/tex]

[tex]x=0.5[/tex]

Therefore, the trip to the airport is 0.5 km.
