Answer:
the answer is A. 3225
Step-by-step explanation:
S₃₀ = 30/2 [ 2 x 6 + (30 - 1) x 7 ]
15 [ 12 + 29 x 7 ]
15 [ 12 + 203 ]
15 x 215

A Cylinder has a radius of 10 feet and a height of 11.4 feet what is the approximate volume of the cylinder?
Answer:
3579.6 [tex]ft^{3}[/tex]
Step-by-step explanation:
First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.
I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.
Step-by-step explanation:
area of circle = r×r×π
area of circle × height = volume
10 × 10 × π = 314.16
314.16 × 11.4 = 3581.42
Solve algebraically the simultaneous equations
x^2+y^2=25
y-3x=13
Answer:
In the form of (x,y) there are 2 solutions:
(-3,4)
(-24/5, -7/5)
Step-by-step explanation:
First isolate one of the letters (for me I'm using the y of equation 2 because it's easier to solve)
[tex]y-3x=13\\y=13+3x[/tex]
Now that we have y isolated, substitute y in equation 1 with the equation we got previously (y=13+3x)
[tex]x^2+(13+3x)^2=25[/tex]
Now simplify:
[tex]x^2+(13+3x)^2=25\\x^2+9x^2+78x+169=25\\10x^2+78x+169=25[/tex]
Now turn the equation into ax^2+bx+c=0 form by transferring 25 to the other side of the equation:
[tex]10x^2+78x+169=25\\10x^2+78x+169-25=0\\10x^2+78x+144=0[/tex]
Using the quadratic formula we will have the 2 following values:
[tex]x=-3[/tex]
[tex]x=-\frac{24}{5}[/tex]
Substitute the following values into any equation you want (this time I'll pick equation 2 again since its the easiest to solve)
[tex]y-3x=13\\y-3(-3)=13\\y-(-9)=13\\y+9=13\\y=13-9\\y=4[/tex]
[tex]y-3x=13\\y-3(-\frac{24}{5})=13\\y-(-\frac{72}{5})=13\\y+\frac{72}{5}=13\\y=13-\frac{72}{5}\\y=-\frac{7}{5}[/tex]

Answer:
26% of 200 is 52.
Step-by-step explanation:
Convert 26% into a decimal, which is 0.26.Multiply 0.26 by 200, which is 52. This is your answer.in the year 2001, a company made 7.7 million dollars in profit. For each consecutive year after that, their profit increased by 7%. How much would the company's profit be in the year 2004, to the nearest tenth of a million dollars?

Misha bought a dress for $35.95 and a hat for $12.98. If the sales tax
was 6%, then what is the total price Misha should have paid for the
dress and hat? Round your answer to the nearest hundredth.
A> $29.36
B
$48.93
$51.87
D> $54.93
Answer: $51.87
Step-by-step explanation:
35.95+12.98 = 48.93
48.93 times .06 = 2.9358 (round that to 2.94)
48.93 + 2.94 = 51.87

[tex]40 \times 0.80 = 32[/tex]
[tex]32 \times 12 = 384[/tex]
He gains £384
[tex]40 - 32 = 8[/tex]
[tex]8 \div 2 = 4[/tex]
[tex]2(12) + 2(6) = 36[/tex]
He gains £36
//
[tex] - 130 + 384 + 36 = 290[/tex]
Ryan made £290
//
I'm not too sure about this...
Anyway if he sold 80% of the jumpers at a normal price, he would earn £384.
There are 8 left and he managed to sell half of those but there is a promo where you can buy one at full price and get one for half the price so only two of the four can be bought at full price while the other two gets bought at half price. He earns £36 from this.
If you take in account the starting cost and add the profits, he made a total of £290 selling jumpers.
But again, I'm not too sure.

Students drop a 2 kg object from rest out a window that has a
height of 10 m during a lab experiment. The students time the
object to hit the ground and measure 1.2 s. Calculate the
difference between the PE at the top and the KE at the bottom.
a. greater than 75 J
b. less than 25 J
c. between 25 J & 50 J
d. between 50 J & 75 J
Answer:
a. greater than 75 J
Step-by-step explanation:
Potential Energy at the top = mgh
Mass m = 2kg
g = 9.8m/s^2
height h = 10m
Potential Energy at the top = 2 * 10 * 9.8
Potential Energy at the top = 196Joules
The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules
difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules
Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules
