Answer:
408.2cm
Step-by-step explanation:
Given data
Area of base= 25πcm^2
Height= 8cm
Let us find the radius of the cylinder
Area= πr^2
25π= πr^2
25= r^2
r= √25
r= 5cm
Let us now find the surface area
SA=2πrh+2πr^2
Substitute
SA= 2*3.14*5*8+ 2*3.14*5^2
SA= 251.2+ 157
SA= 408.2cm
Hence the surface area is 408.2cm

Answer:
m∠XCY = 60°
Step-by-step explanation:
From the figure attached,
Circle has been given with the inscribed angles ∠XWY and ∠XCY formed by the same arc XY.
By the property of the inscribed angles,
"Measure of the inscribed angle formed by the same arc are equal"
m∠XWY ≅ m∠XCY
60x = 61x - 1
61x - 60x = 1
x = 1
Therefore, m∠XCY = 61x - 1
= 61(1) - 1
= 60°

A man has Rs 1900. he lent some of it at 5% p.a and rest at9% p.a. The total amount of interest which he got after4 years was Rs 580.Wwhat was the sum
ans= Rs650,Rs 1250
Answer:
The sum is Rs 1,250 and Rs 650
Step-by-step explanation:
Let the amounts be represented as $x and $y
The sum of both is 1900
Thus;
x + y = 1,900 •••••(i)
Mathematically, the interest on the amount borrowed is;
I = PRT/100
where p is the principal, representing the amount borrowed
R is the rate
T is the time
for the first amount of $x ; we have interest as;
I = (x * 5 * 4)/100 = 20x/100
for the second, we have
I = (y * 9 * 4)/100 = 36y/100
The sum of both is 580
Thus;
20x/100 + 36y/100 = 580
20x + 36y = 58000 •••••(ii)
From equation i;
x = 1,900 - y
Substitute this into equation ii
We have this as;
20(1900-y) + 36y = 58,000
38000 - 20y + 36y = 58,000
16y = 58000 - 38000
16y = 20,000
y = 20,000/16
y = 1250
From equation 1;
x + y = 1900
x = 1900-y
x = 1900-1250
y = 650

Select all correct ways of factoring –3x – 9.
Answer:
Some possible expressions, since there's no answer choices provided:
-3(x + 3)
3(-x - 3)
Step-by-step explanation:
Expression 1:
This uses a GCF of -3, since -3x and -9 are divisible by this. Let's divide -3x and -9 by this first:
-3x / -3 = x
-9 / -3 = 3
So now, we can add these terms and multiply them by -3 to get our answer:
-3(x + 3)
And just to check, we can expand it:
-3x + -3(3) = -3x - 9
Expression 2:
This uses a GCF of 3, like the last one but it's negative. -3x and -9 are also divisible by this. Let's divide both terms by this GCF first:
-3x / 3 = -x
-9 / 3 = -3
Now, we can add these terms and multiply them by -3 to get our final answer:
3(-x - 3)
To check, once again:
-3x + 3(-3) = -3x - 9

6x^2 + 6 = 12x + 18
[tex]x = 1 + \sqrt{3} [/tex]
[tex]x = 2 + 2 \sqrt[]{3} [/tex]
[tex]x = 2 + \sqrt{6} [/tex]
[tex]x = - 1 \: and \: x = 3[/tex]
Answer:
x=1+√3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x^2+6=12x+18
Step 1: Subtract 12x+18 from both sides.
6x^2+6−(12x+18)=12x+18−(12x+18)
6x^2−12x−12=0
For this equation: a=6, b=-12, c=-12
6x^2+−12x+−12=0
Step 2: Use quadratic formula with a=6, b=-12, c=-12.
x=−b±√b2−4ac/2a
x=−(−12)±√(−12)2−4(6)(−12)/2(6)
x=12±√432/12
x=1+√3

Answer:
X = 64
Step-by-step explanation: The square in the corner indicates a 90 degree angle. by adding everything but X and subtracting that from 360 degrees we can get X. 180+90+26=296 360-296=64
Answer:
64°Step-by-step explanation:
We know that this need to total to 360°. Since we know this, it is simple and straight forward.
To find x, we need to add up all the known degrees.
180 + 90 + 26 = 296
Also if you do not know how I got 90, there is a right angle which is 90 degrees.
Now that we have the sum of the known degrees, we take that number and subtract that from 360
360 - 296 = 64
So our final answer is 64°

Find the minimum value of the function f(x) = 0.8x2 + 11.2x + 42 to the
nearest hundredth.
Answer:
The minimum value is 2.8. The vertex is (-7, 2.8).
Step-by-step explanation:
Through the x^2 term we identify this as a quadratic function whose graph opens up. The minimum value of this function occurs at the vertex (h, k). The x-coordinate of the vertex is
-b 11.2
x = --------- which here is x = - ------------ = -7
2a 2(0.8)
We need to calculate the y value of this function at x = -7. This y-value will be the desired minimum value of the function.
Substituting -7 for x in the function f(x) = 0.8x^2 + 11.2x + 42 yields
f(-7) = 0.8(-7)^2 + 11.2(-7) + 42 = 2.8
The minimum value is 2.8. The vertex is (-7, 2.8).

is 15m 36m 39m right triangle
Answer is below. Look at my explanation to understand my answer.
To see if these lengths can make a triangle, we can use the "triangle side theorem."
The formula is:
a + b > c
a + c > b
b + c > a
So, with that being said...
15 → A
36 → B
39 → C
So, we can use the triangle side theorem by adding A & B, A & C, and B & C.
If the side length is greater than C, B, or A, it can make a triangle. But if it isn't greater than C, B, or A, it cannot make a triangle.
So, let's add 15 and 36 to see if it can make a triangle.
15 + 36 = 51
If you read above, C is 39.
So, 51 > 39
15 + 36 > 39 ✓
Let's repeat this process again.
Instead of C, B is what we're now seeing if the sum is greater than it.
15 + 39 = 54
54 is greater than 36...
54 > 36
So it is true.
15 + 39 > 36 ✓
Now, A is what we're seeing if the sum is greater than it.
36 + 39 = 75
75 is greater than 15...
75 > 15
So it is true.
36 + 39 > 15 ✓
So yes, these lengths can make a triangle.
Let me know of any questions or concerns.

Erica babysits for 4 1/2 hours and is paid $27 . If the people she babysits for have $31.50 to pay her, how long can they stay out?
Answer:
5.25 hours or 5 1/4 hours
Step-by-step explanation:
According to the scenario, calculation of given data are as follows,
Total time = 4 1/2 hours or 270 mins
Total payment = $27
First we calculate the time for $1, then
So, $27 = 270 mins
$1 = 270 ÷ 27 = 10 mins
Now, we can calculate total time in $31.50 by using following formula,
Total time in $31.50 = 10 mins × 31.50
= 315 mins
= 5.25 hours or 5 1/4 hours
