A square pyramid and its net are shown below. What is the surface area of the pyramid?

Answer:if you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).

Step-by-step explanation:

Scale factor are used to increase or diminish the original figrure. The new volume will be 8times larger than the initial volum

Scale factor are used to increase or diminish the original figrure.

Assume the original dimension of the figure is a, b and c, the volume of te figure will be expresed as:

A = length * width * heiht

A = abc

If the measure of the sides are doubled, hence;

New volume = 2a * 2b * 2c

New volume = 8abc

Ratio = 8abc/abc
Ratio = 8

Hence the new volume will be 8times larger than the initial volume

Answer:

m∠QPR = 20°

Step-by-step explanation:

If we make a sketch of the triangle, it will be observed, that line R bisects angle P.

Considering Triangle, ΔQPS;

∠QPS=107∘

Considering triangle, QPR;

∠QPR=9x-115∘

Considering triangle, RPS;

∠RPS=4x+27∘

Thus, ∠RPS + ∠QPR = ∠QPS

4x+27° + 9x-115° = 107°

13x - 88° = 107∘

13 x = 107∘ + 88∘

13x = 195°

x = 195°/13

x = 15°

m∠QPR = 9x - 115°

= (9 x 15) - 115°

= 135° - 115°

= 20°

Therefore, m∠QPR = 20°

Answer:

C. If you flip a coin, it will come up either heads or tails.

Step-by-step explanation:

A. My guess is it doesn't rain much in Phoenix in July. A probability of 1 means it will happen for sure, so this is not it.

B. A die has 3 even numbers and 3 odd numbers. The probability of rolling an even number is 3/6 = 0.5. This is not it.

C. If you flip a coin, you either get heads or tails. The probability of heads or tails is 1 since one of the two outcomes will always happen. This is the answer.

D. The probability of the birth of a girl is 1 out of 2, so it is 0.5. This is not it.

Answer:

If you flip a coin, it will come up either heads or tails. It either will fall on heads or tails everytime so that is closest to one.

Answer:

3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the length of the other leg, then

x² + 3² = 6², that is

x² + 9 = 36 ( subtract 9 from both sides )

x² = 27 ( take the square root of both sides )

x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex] ← exact value

Answer:

x = -6

Step-by-step explanation:

0 = In(x + 7)

x + 7 = e⁰

x + 7 = 1

x = 1 - 7

x = -6

Steps to solve:

0 = In(x + 7)

~Log definition

e^0 = x + 7

~Simplify

1 = x + 7

~Solve for x

1 - 7 = x + 7 - 7

-6 = x

Therefore, the answer is x = -6

Answer:

The value of x is D) 90°

Step-by-step explanation:

The sum of interior angles in a quadrilateral is 360°

As the total interior angles in a quadrilateral is 360 to work this out you would first need to work out the total of the angles given You can do this by adding 101 and 75 and 94, this gives you 270. This is because it tells us how much of that 360 degree total has been used.

The next step is to work out the angle of x. You can do this by subtracting the total angles gives of 270 from the total of 360, this gives you 90 degrees. This is because by subtracting it we are isolating the value of x.

1) Add the values of 94, 101, 75.

[tex]101+94+75=270[/tex]

2) Minus 270 from 360.

[tex]360-270=90degrees[/tex]

Answer:

26

Step-by-step explanation:

I subtracted DF and DE to find the missing difference for the segment EF. I'm not sure if this is correct though. I hope it helps.

The length of line segment EF is 26.

A line segment is a subset of a line which has two endpoints.

A ray has one end point and extends indefinitely on the other direction.

A line extends indefinitely on both of it's directions.

From the given data

Line segment DF has a length 38 and line segment DE has a length 12.

To find the length of line segment EF we have to subtract the length of line segment DE from length segment DF.

∴ EF = DF - DE

  EF = 38 - 12'

  EF = 26.

So, the line segment EF has a length of 26.

We have been given a circle with a tangent and a secant, which are intersecting at an angle 38 degrees. We are asked to find the measure of arc g.

We can see that angle with 38 degrees measure is a secant tangent angle outside the circle.

We know that measure of an angle formed by intersection tangent and secant outside circle is half the difference of intercepted arcs.

[tex]38^{\circ}=\frac{1}{2}(119^{\circ}-g^{\circ})[/tex]

[tex]38^{\circ}\cdot 2=\frac{1}{2}\cdot 2(119^{\circ}-g^{\circ})[/tex]

[tex]76^{\circ}=119^{\circ}-g^{\circ}[/tex]

[tex]76^{\circ}+g^{\circ}=119^{\circ}-g^{\circ}+g^{\circ}[/tex]

[tex]76^{\circ}+g^{\circ}=119^{\circ}[/tex]

[tex]76^{\circ}-76^{\circ}+g^{\circ}=119^{\circ}-76^{\circ}[/tex]

Answer:∠M in the pre-image corresponds to ∠B in the image.

Step-by-step explanation:

When  we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N  ,O .

Clearly , vertex C corresponds to vertex N ( presents in the middle )

Also, point B is at the right from point C .In  Figure L M N O P , vertex M is at the right from vertex N .Thus , vertex M corresponds the vertex B.

It means ∠M in the pre-image corresponds to ∠B in the image.

We see for each row the x coordinates are in arithmetic progression, with a constant difference between successive points.  For example in A x coordinates 3-5=1-3.   So for this to be a line, the same has to be true of the y coordinates; they have to be in arithmetic progression.

A.  5/2, 3/2, 1/2 is just 5,3,1 (constant factors don't matter) so those are in arithmetic progression like the x coordinates so we have a line.

B. 1/2, 1, 3/2.  In AP, a line

C. -1/2, -1/3, -1/4 multiplying by common denominator -12 makes 6, 4, 3.  Those aren't in arithmetic progression.  Not a line.

Step-by-step explanation:

Answer:

The simple interest rate on the student loan is 6%.

Step-by-step explanation:

To solve for the simple interest rate, use the formula for total simple interest:

[tex]I = Prt[/tex]

[tex]I[/tex] = total interest paid

P = principal, or starting value

r = interest rate in decimal form

t = time in years

State known values

P = 12,000

t = 5

[tex]I[/tex] = 3,600

Substitute known values and isolate "r"

[tex]I = Prt[/tex]

3,600 = (12,000) (r) (5)

3,600 = (60,000) r

r = 0.06

Since "r" is given as a decimal, convert this to a percentage by multiplying by 100.

0.06 = 6%

∴ The simple interest rate on the student loan is 6%.

Answer=6%

Step-by-step explanation:

Principal(P)=12000

Time(T)=5  yrs

Interest(I)=3600

We have,

I=PTR/100

3600=(12000*5*R)/100

3600*100=60000*R

R=360000/60000

R=6%

where s is the edge length of the cube-shaped box

Step-by-step explanation:

Let the edge length of the cube-shaped box=s

The edge length of a cube-shaped crate is the square of the edge length of a cube-shaped box.

To determine the number of boxes that can fit in the crate, we first find the volume of the crate and the box.

Therefore, the number of boxes that can fit in the crate

=Volume of Crate divided by Volume of Box

[tex]=\frac{s^6}{s^3}\\=s^{6-3}\\=s^3$ boxes[/tex]

Therefore, an expression for the number of boxes that can fit in the crate is [tex]s^3[/tex].

Answer:

Option D

One worker works for much fewer hours than everyone else

Step-by-step explanation:

First of all, we will need to clarify the concepts.

The median of a distribution is the middle number in that distribution, after the values have been arranged in either an ascending or descending order.

The mean is a weighted average of a distribution.

The mean has the characteristic of  usually being affected by extremely low or extremely high values.

In our case, we have a relatively low value in terms of hours worked. This means that in the distribution, the worker that worked only 20 hours, will affect the mean hours worked by all the workers, making it lower than the median value.  

Means give better results, when used to analyse distributions with smaller ranges.
