How is 1.35 x 10 -5 written in standard notation?

Answer:

The volume of the candle is [tex]147\ in^{3}[/tex]

Step-by-step explanation:

we know that

The volume of a cylinder (candle) is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=5/2=2.5\ in[/tex] ----> the radius is half the diameter

[tex]h=7.5\ in[/tex]

substitute

[tex]V=\pi (2.5)^{2} (7.5)[/tex]

[tex]V=46.875\p\ in^{3}[/tex]

assume

[tex]\pi=3.14[/tex]

[tex]V=46.875(3.14)=147\ in^{3}[/tex]

Answer:

We first have to find the volume of the cube: (0.3 * 0.3 * 0.3) we then get 0.027, then we plug in the numbers for the density formula. D = 18.954/0.027 will give us 702.

The density of the wooden block in the shape of a cube with the given side length and mass is 702kg/m³.

Density is expressed mathematically as;

p = m / v

Where m is mass and v is volume.

Given the data in the question;

First, we calculate the volume of the cube wood block.

Volume of a cube v = a³

v = ( 0.3m )³

v = 0.027m³

Now, we determine the density.

p = m / v

p = 18.954kg / 0.027m³

p = 702kg/m³

Therefore, the density of the wooden block in the shape of a cube with the given side length and mass is 702kg/m³.

Answer:

the answer is A.  1  9/16 cubic feet

Step-by-step explanation:

V = lwh

V = (5/3 ft) (5/4 ft) (3/4 ft)

V = 75/48 cu. ft.

V = 25/16 cu. ft.

V = 1  9/16 cu. ft

The median of injured players in a match is found by arranging the number of injuries in each game in ascending order and identifying the middle value. The method slightly varies depending on whether the total number of matches is odd or even. The question lacks specifics for a detailed calculation.

To find the median of injured players, you need to arrange the number of injured players in each match in ascending order and identify the middle value. However, your question doesn't provide the specifics of the frequency table for me to proceed with a step-by-step calculation. The median is found differently depending on whether there's an odd or even number of matches. If there's an odd number of matches, the median would be the value directly in the middle of the organized list. If it's an even number, you'd average the two middle values.

Answer:

D

Step-by-step explanation:

General Equation: y = mx + b

You need two pieces of data to solve this.

When x = 1, y = 8

8 = 1x + b

When x = -1, y = 3

3 = - x + b

==================

8 = x + b

3 = -x + b     If we add we get b so let's add.

11 =2b          Divide by 2

11/2 = b

==================

y = mx + b

y = mx + 11/2      Now we can solve for m

3 = -m + 11/2      Subtract 11/2

3 - 11/2 = - m

- 2  1/2 = -m        multiply by - 1

2  1/2 = m

m = 5/2

The total number of pieces in the puzzle’s is 3,750 pieces.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

we have,

3 puzzle having 1250 pieces in each.

Answer:

(3, 2)

Step-by-step explanation:

This is a system of equations so I'll solve it using the 'Addition method'.

3x - 2y = 5 | x + 2y = 7

Add the two equations together to get:

4x = 12

x = 3

Then we solve for y using the 2nd expression because it's easier.

3 + 2y = 7

2y = 4

y = 2

The point of intersection of the two lines 3x-2y=5 and x+2y=7 is found to be (3,2) by solving the system of equations simultaneously, making option A the correct answer.

To find the point of intersection of the two lines represented by the equations 3x−2y=5, and x+2y=7, we need to solve these equations together. This involves finding a common solution for x and y that satisfies both equations simultaneously.

Steps to Find the Intersection

Therefore, the point of intersection of the two lines is (3,2), which corresponds to option A.

B: 292.5; multiply 65x4.5

Using the formula d = rt, the distance traveled by a car moving at 65 miles per hour for 4.5 hours is calculated to be 292.5 miles.

Calculating Distance Traveled

To calculate the distance traveled by a car, we can use the formula d = rt, where d represents distance, r represents average speed (rate), and t represents time.

Given: average speed r = 65 miles/hour, time t = 4.5 hours.

Find: distance d.

We use the formula to solve for d:

d = (65 miles/hour)(4.5 hours) = 292.5 miles

Therefore, the car would travel a distance of 292.5 miles at an average speed of 65 miles per hour over 4.5 hours.

Answer:

see explanation

Step-by-step explanation:

Given

5x² - 4 - 8x

To find the zeros equate to zero and rearrange into standard form, that is

5x² - 8x - 4 = 0 ← in standard form

To factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × - 4 = - 20 and sum = - 8

The factors are - 10 and + 2

Use these factors to split the x- term

5x² - 10x + 2x - 4 = 0 ( factor the first/second and third/fourth terms )

5x(x - 2) + 2(x - 2) = 0 ← factor out (x - 2) from each term

(x - 2)(5x + 2) = 0

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

5x + 2 = 0 ⇒ 5x = - 2 ⇒ x = - [tex]\frac{2}{5}[/tex]

-----------------------------------------------------------------------------

The sum of the zeros = - [tex]\frac{b}{a}[/tex]

The product of the zeros = [tex]\frac{c}{a}[/tex]

with a = 5, b = - 8 and c = - 4

The sum = 2 - [tex]\frac{2}{5}[/tex] = [tex]\frac{8}{5}[/tex]

and - [tex]\frac{b}{a}[/tex] = - [tex]\frac{-8}{5}[/tex] = [tex]\frac{8}{5}[/tex]

Thus verified

The product = 2 × - [tex]\frac{2}{5}[/tex] = - [tex]\frac{4}{5}[/tex]

and [tex]\frac{c}{a}[/tex] = [tex]\frac{-4}{5}[/tex] = - [tex]\frac{4}{5}[/tex]

Thus verified

A. 48.35°, 94.94°, 36.71°

Step-by-step explanation:

Given,

ABC is a triangle,

In which AB = 12 miles, BC = 15 miles and AC = 20 miles,

By the cosine law,

[tex]BC^2 = AC^2 +AB^2 -2\times AC\times AB\times cos A[/tex]

[tex]2(AC)(AB)cos A=AC^2+AB^2-BC^2[/tex]

[tex]\implies cos A = \frac{AC^2+AB^2-BC^2}{2(AC)(AB)}----(1)[/tex]

Similarly,

[tex]cos B = \frac{BC^2+AB^2-AC^2}{2(BC)(AB)}----(2)[/tex]

[tex]cos C = \frac{BC^2+AC^2-AB^2}{2(AC)(BC)}----(3)[/tex]

By substituting the values in equation (1),

[tex]cos A=\frac{20^2+12^2-15^2}{2(20(12)}=0.66458[/tex]

[tex]\implies m\angle A\approx 48.35^{\circ}[/tex]

Similarly, from equation (2) and (3),

[tex]m\angle B\approx 94.94^{\circ}[/tex]

[tex]m\angle C\approx 36.71^{\circ}[/tex]

Hence, Option 'A' is correct.

Answer:

175.415

Step-by-step explanation:

surface area of square pyramid is given by:

Area= s^2 + 2(s)(l)

where s is the base and l is the slant height

in given problem, slant height l is not given, so by using Pythagoras theorem finding l:

c^2= a^2 + b^2

     =  8^2 + 4^2

     = 48.49

c     = 6.96348

Now putting values of s=8 and l= 6.96 in first formula

Area= 8^2 + 2(8)(6.96)

      =  64 + 111.41

      = 175.415
