1. Solve for q:
√3q + 2 = √5
2. solve for d:
4d + 1 = √3
3. Solve for m:
m/√3 - 11 = 4
Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2
3m^2/9-121=16
3m^2/9=137
m^2/3=137
m^2=411
m=√411

The answer gonna be B

Answer:
A
Step-by-step explanation:
We can see that our figure is composed of a cylinder and a cone.
So, we can utilize the surface area formulas.
The surface area of a cylinder is given by:
[tex]SA=2\pi r^2+2\pi r h[/tex]
The first term is the two circular bases, and the second term is the lateral surface area.
Notice that the circular base has a diameter of 6. So, its radius is 3.
Also, the height of the cylinder is 50.
However, notice that one of the circular bases is not included in our surface area as it’s connected to the cone. So, we will remove that from our surface area. This gives us:
[tex]SA=\pi r^2+2\pi rh[/tex]
Therefore, by substituting 3 for r, the radius, and 50 for the height h we can see that:
[tex]\begin{aligned}SA&=\pi(3)^2+2\pi(3)(50)\\&=9\pi+300\pi\\&=309\pi\end{aligned}[/tex]
Now, we can determine the SA of the cone.
Again, we will only need to lateral surface area, since the circular base is connected to the cylinder.
The lateral surface area of a cone is given by the formula:
[tex]SA=\pi r\ell[/tex]
Where r is the radius and l is the slant height.
The radius is 3 and the slant height is 5. Therefore:
[tex]SA=\pi(3)(5)=15\pi[/tex]
So, our total surface area is:
[tex]SA_{\text{Total}}=309\pi+15\pi[/tex]
Simplify:
[tex]SA_{\text{Total}}=324\pi\\[/tex]
Approximate:
[tex]SA_{\text{Total}}\approx1017.9\text{ units}^2[/tex]
Hence, our answer is A.

Answer:
Option B
Step-by-step explanation:
Given equation gives the information about the temperature in Vancouver over a period of 4 hours.
y = -2x + 43
Here 43 represents the initial temperature and (-2) represents the temperature fall in every one hour.
x = duration or time
Therefore, equation states that initial temperature when measured was 43 °F and it is dropping by 2 degrees per hour.
Option B is the answer.

4,4.1,4.2,4.3,4.4
Common Difference: d=
what is the common difference?
Answer:
0.1 is the answer...............
The common difference [tex](d)[/tex] of Arithmetic Sequences [tex]4,4.1,4.2,4.3,4.4[/tex] is [tex]0.1[/tex] .
What is Arithmetic Sequence ?Arithmetic Sequence is also known as arithmetic progression and is a sequence of numbers in which the difference between the consecutive terms is constant.
What is common difference ?Common difference is the difference between two consecutive terms of an arithmetic progression.
We have arithmetic progression,
[tex]4,4.1,4.2,4.3,4.4[/tex]
Here,
[tex]a_{1} =4[/tex]
[tex]a_{2} =4.1[/tex]
[tex]a_{3} =4.2[/tex]
[tex]a_{4} =4.3[/tex]
[tex]a_{5} =4.4[/tex]
And,
Common Difference [tex](d)[/tex] [tex]=a_{2} -a_{1} =a_{3} -a_{2} =a_{4}-a_{3}[/tex]
So,
Common Difference [tex](d)[/tex] [tex]= 4.1-4[/tex]
[tex]=0.1[/tex]
So, Common Difference [tex](d)[/tex] is [tex]0.1[/tex] which is the difference of consecutive terms of Arithmetic Sequences.
Hence, we can say that the common difference [tex](d)[/tex] of Arithmetic Sequences [tex]4,4.1,4.2,4.3,4.4[/tex] is [tex]0.1[/tex] .

One of the Great Pyramids in Egypt has the shape of a square pyramid with the base length of 20 feet, and the height of 150 feet tall. If the stones that were used to build the pyramid had a volume of 40 cubic feet each, how many stones did the Egyptians need to build the pyramid?
Answer:
500
Step-by-step explanation:
Given that:
Shape of one of the Great Pyramids in Egypt is a square pyramid.
Base of pyramid is of square shape with length = 20 feet
Height of pyramid = 150 feet
Volume of each stone used for the construction of the pyramid = 40 cubic feet
To find:
Number of stones used for the construction of the pyramid.
Solution:
First, we need to find the volume of the square pyramid and then we need to divide the volume of pyramid with the volume of one stone used for the construction.
It will give us the number of stones used for the construction of pyramid.
Volume of a pyramid is given as:
[tex]V = \dfrac{1}{3}\times \text{Area of base}\times Height[/tex]
Here, base is a square, so area of base = [tex](Side)^2[/tex]
[tex]V = \dfrac{1}{3}\times 20^2\times 150 = 400\times 50 ft^3[/tex]
Number of stones of 40 cubic feet each, required = [tex]\frac{400\times 50}{40}[/tex] = 500

Answer:
p=0.75$
d=1.25$
Step-by-step explanation:
2p+2d=4
So 2p=4-2d
2p+3d=5.25
4-2d+3d=5.25
d=5.25-4
d=1.25
2p+1.25*2=4
2p=4-2.5
2p=1.5
p=0.75

The zero property of multiplication states that any non-zero number multiplied by zero will equal zero.
it can't be the first one, since there's no zero in it, and the answer isn't zero
it can't be the second one since there's no multiplication illustrated.
The third one is an option, since there is a zero and it's being multiplied by two non-zero numbers, and the answer is 0
the fourth one isn't an option since there's no multiplication
the fifth one isn't an option since there is no 0's there.
