Answer:

Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, ([tex]\pi[/tex]) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Substitute,
[tex]a^2+(1)^2=(5.1)^2[/tex]
Simplify,
[tex]a^2+1=26.01[/tex]
Inverse operations,
[tex]a^2=25.01\\a\approx5[/tex]
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
[tex]A=(\pi)(r)(r+\sqrt{h^2+r^2}})[/tex]
Substitute,
[tex]A=(\pi)(1)(1+\sqrt{5^2+1^2}})[/tex]
[tex]A=(\pi)(1+\sqrt{25+1})\\A=\pi(1+\sqrt{26})\\A\approx 19.16[/tex]

Answer:
y= -2x+ 5
Step-by-step explanation:
parallel with y= -2x+ 1 means the lines have the same slope m= -2
from point (-1, 7) we go with a slope of -2 until we find the y-intercept (0, 5)
y= mx+b is the general formula
y= -2x+ 5

y = 7x
y - x = 15
Answers
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5

Answers
Answer:
D)
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4
Answer:
D is the answer
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4

A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?
Answers
Answer:
$14.70
Step-by-step explanation:
Find the 30% decrease:
21*0.3 = 6.3
Find new price:
21-6.3 = 14.7
Answer:
$14.7
Step-by-step explanation:
First, we need to convert the percentage to a decimal. 30% = .30
Now we multiply the price times the decimal, 21 x .30 = 6.3
We subtract this amount from the previous cost. 21 - 6.3= $14.7

Answer: The answer is x=[tex]\frac{-3-\sqrt{65} }{4}[/tex], [tex]\frac{-3+\sqrt{65} }{4}[/tex]
Step-by-step explanation:
1) You can solve a situation like [tex]ax^2+bx+c=0[/tex] using the quadratic formula
[tex]x=-b[/tex]±[tex]\sqrt{b^2-4ac}[/tex] / 2a
2) Apply that to the problem and we get x= -3±[tex]\sqrt{3^2-4*2*(-7)}[/tex]/2*2
3) Solve what's inside the square root and what's at the denominator --> x=-3±[tex]\sqrt{65}[/tex]/4
4) separate the solutions ---> [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]
5) Your final solutions are [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

Mr. Gephart is traveling from his house to the history museum. How many meters will he travel to the museum? The distance from home to the history museum is six and seven-tenths kilometers.
Answers
Answer: 6700 meters
Step-by-step explanation:
From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.
In order to know the distance in meters
that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:
1000 meters = 1 kilometer
Therefore, 6 7/10km = (6 7/10 × 1000m)
= 6 7/10 × 1000
= 67/10 × 1000
= 67 × 100
= 6700 meters
He'll travel 6700 meters to the museum.

Answers
Answer:
(x+3)/(x-4)
Step-by-step explanation:
[2x²/(x-4)(x-3)] - [x²+9/(x-4)(x-3)] =
(x²-9)/(x-4)(x-3) =
(x+3)(x-3)/(x-4)(x-3) =
x+3/x-4
Answer:
2x²/x² - 7x + 12 - x² + 9/x² - 7x + 12
2x²/x² simplifies to just 2 (the x²s cancel out)
2 - 7x + 12 - x² + 9/x² - 7x + 12
add like terms: (2 + 12 + 12) + (-7x - 7x) - x² + 9/x²
= - x² - 14x + 9/x² + 26

A rectangular flower bed has a width of (2x+5) and a length of (x+10). Find the area of the flower bed when the length is 25 ft
Answers
Answer:
875 ft
Step-by-step explanation:
Length is 25 feet so we can solve x with the equation x+10=25 so x=15
We can plug in 15 to find out the width. 2(15)+5=w, so w(width) is 35.
Area is length x width, length=25 and width=35 so 35 x 25= 875
875 ft
