Answer:
[tex]A = 329.7[/tex]
Step-by-step explanation:
Given
[tex]h = 15[/tex] --- height
[tex]d = 7[/tex] --- diameter
Required
Paper needed to cover the sides
To do this, we simply calculate the surface area of the cylinder (without considering the top and bottom)
This is calculated as:
[tex]A = 2\pi rh[/tex]
Where
[tex]r = \frac{d}{2}[/tex]
[tex]r = \frac{7}{2}= 3.5[/tex]
The formula becomes
[tex]A = 2 * 3.14 *3.5 *15[/tex]
This gives:
[tex]A = 329.7[/tex]

A total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets. How many adult tickets were sold?
The number of adult tickets sold will be 275.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that a total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets.
Assume that the number of adult tickets sold are [x] and the student tickets sold are [y]. Then -
x + y = 494
y = x - 56
So, we can write the equation as -
x + x - 56 = 494
2x = 550
x = 275
Then, we can find [y] as -
y = 275 - 56 = 219
y = 219
Therefore, the number of adult tickets sold will be 275.

H
57°
F
Answer:
m<G = 59°
Step-by-step explanation:
Recall: the angle formed outside a circle when 2 secants intercept is equal to half of the difference of the intercepted arcs
m<G = ½(arc TE - arc HF)
m<G = ½(175 - 57)
m<G = ½(118)
m<G = 59°
Simplify c^3d^4/c^2d
Answer:
I think the answer is :-
[tex]c {d}^{3} [/tex]
The simplification of c^3d^4/c^2d is cd^3.
What is simplification of an expression?Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.
For the given situation,
The expression is c^3d^4/c^2d.
The simplification is as
⇒ [tex]\frac{c^{3}d^{4} }{c^{2}d }[/tex]
⇒ [tex]\frac{(c^{2})( c)(d^{3} )(d)}{c^{2} d}[/tex]
⇒ [tex]cd^{3}[/tex]
Hence we can conclude that the simplification of c^3d^4/c^2d is cd^3.

Can side lengths 3, 4, and 5 form a right triangle
Answer:
Yes it can! Plz the Brainliest!
Step-by-step explanation:
A right triangle is defined as a triangle with sides in the ratio 3:4:5. Pythagorean Doubles are triangles whose sides have had a ratio of the whole numbers as their sides. Even if the sides are multiplied by any number, the result is still a right triangle with sides in the ratio 3:4:5. For instance, 6, 8, and 10 are all numbers.

A circular path 4 feet wide has an inner diameter of 250 feet. How much farther is it around the outer edge of the path than around the inner edge? Round to nearest hundredth. Use 3.14 for π.
The outer edge of the path is ??? feet farther around than the inner edge.
Answer:
25.13
Step-by-step explanation:
the inner circle is 1570.8 and the outer is 1595.93
Hope this helps! :)
Have a great weekend!! :)
Answer:
50.24 ft
Step-by-step explanation:
diameter = 250 ----- radius = 125 (radius of the smaller circle)
125+4 = 129 ( radius of the bigger circle)
129-125 = 4
4² x pi = 16x 3.14 = 50.24

In the isosceles trapezoid ABCD, find m
Answer:
answer C
Step-by-step explanation:
Isosceles trapezoids have the property that opposite angles are supplementary.
Here are some needed properties of isosceles trapezoids.
<C and <D are supplementary
<A = <D
<B = <C
<D + <B = 180
<D = 110 Given
110 + <B = 180 Subtract 110 from both sides..
<B = 70

17. The present age of a father and his son is 50yrs and 20yrs respectively. How many years ago
the product of their ages was 451.
Answer:
9 yrs ago
Step-by-step explanation:
(50-x)(20-x) = 451
x^2-70x + 1000 = 451
x^2-70x + 549 = 0
(x-9)(x-61) = 0
x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

Find the height and slant height of the cone. Round your answers to the nearest whole number.
Answer:
Height = 4 cm and slant height = 5 cm
Step-by-step explanation:
Given that,
The surface area of the cone, A = 75.4 cm²
Radius, r = 3 cm
The surface area of the cone is given by the formula as follows :
[tex]A=\pi r^2+\pi rl[/tex]
Put all the values,
[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]
Also,
[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]
Hence, the height of the cone is 4 cm and the slant height is 5 cm.
