Find the lateral area of this cone.
Leave your answer in terms of pi
15cm
8cm
Answer:
lateral surface area of cone =
[tex]\pi rl[/tex]
where, l = slant height, and r = radius
then
[tex]l.a = \pi \times 8 \times 17[/tex]
[tex]l.a = 136\pi[/tex]
The lateral area of this cone will be 136 π. Lateral area is found as the product of pi ,radius and slant height.
What is a cone?It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
lateral area of this cone is found as;
L=πrl
L=π×8×17
L=136π
Hence,the lateral area of this cone will be 136 π.

Junior's brother is 1 1/2
meters tall. Junior is 1 1/5
of his brother's height.
How tall is Junior?
Answer:
Step-by-step explanation:
1 1/5 of 1 1/2 meters
= (1+1/5) x (1+1/2)
= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2
= 1 + 1/2 + 1/5 + 1/10
= 1 + (1x5+1x2+1)/10
= 1 8/10
= 1 4/5 meters
Answer:
1 4/5 meters
Step-by-step explanation:
1 1/5 of 1 1/2 meters
= (1+1/5) x (1+1/2)
= 1x1 + 1x1/2 + 1x1/5 + 1/5*1/2
= 1 + 1/2 + 1/5 + 1/10
= 1 + (1x5+1x2+1)/10
= 1 8/10
= 1 4/5 meters

User averysmartperson is helping with this question.
Answer:
[tex]x^2 + (y-60)^2 = 30,625[/tex]
Step-by-step explanation:
There are 42 carts, so there is 42 spaces in between them; if one of those spaces are 25pi/3 feet long, then 42 of them would be 25*42*pi/3 = 350pi (Perfect! no fractions)
350pi is the circumference. Now if we plug that into the circumference equation we get:
C = 2pi*r
350pi = 2pi*r
Divide both sides by pi to get rid of it
350 = 2r
Divide both sides by 2
r = 175 feet
So the new equation to graph it is:
x^2+y^2 = 175^2 = 30,625
We also know that the center of the Ferris wheel has to be at least 60 feet from the ground. Since the radius is more than that, a good bit of the Ferris wheel has to be underground OR we can make it higher (keyword: at least) if we want it to be above ground. I'll do the equation for underground since it more closely represents the question.
subtracting a number from y, shifts the graph up that much so:
[tex]x^2 + (y-60)^2 = 30,625[/tex]
I can't really draw it electronically but I can graph it:
A picture 10 feet long is to be centered on a wall that is 14 feet long. How much space is there from the edge of the wall to the picture?
Answer:
4 feet is left in the wall
Step-by-step explanation:
If something is 1 foot and it’s supposed to be 2 feet, how much space is left? 1 foot, therefore you have to subtract what you want from what you have.
Answer:
2 ft.
Step-by-step explanation:
14 - 10 = 4.
4/2 = 2
You divide beacuse theres space on botrhsides of the painting.

A right rectangular container is 10 cm wide and 24 cm long and contains water to a depth of 7cm. A stone is placed in the water and the water rises 2.7 cm. Find the volume of the stone.
Answer:
648cm³
Step-by-step explanation:
The container is a cuboid thus:
volume of water is:
v=l×w×h
=10×24×7
=1680cm³
volume of water+stone=10×24×(7+2.7)
=10×24×9.7
=2328cm³
Thus volume of stone equals
2328-1680.
=648cm³
Classify the triangle
Answer:
This triangle is an isosceles acute
Step-by-step explanation:
First lets define each classification
scalene - no equal sides
isosceles - two equal sides
equilateral - all equal sides
acute - all angles have a measure of less than 90 degrees
right - has a right angle (90 degree angle)
obtuse - has an angle that has a measure of more than 90 degrees
Now lets classify
The triangle has two equal sides (indicated by the little line on the top and bottom side) therefore it is an isosceles triangle
We know its an acute triangle because the one angle given is not a right angle nor a obtuse angle meaning that the other two angles are going to have a measure of less than 90 degrees
So we can conclude that this is an isosceles acute triangle

Mai wants to buy a pair of jeans at the mall. The jeans cost $35.00. She has a coupon for that store. She pays $28.00 for the jeans. What was the percent of her discount?
9514 1404 393
Answer:
20%
Step-by-step explanation:
The discount was $35 -28 = $7. As a percentage of the original price, that is ...
$7/$35 × 100% = 20%
Mai's coupon was for a 20% discount.
if 40% percent is a number of 35 what is 50% of that number
Answer:
what is 50% of 35?

What is the inverse relation of f(x)=1/5x−4/5?
y=1/5x−4
y=−1/5x+5/4
y=−5x−4
y=5x+4
Answer:
[tex]y' = 5x + 4[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]
Required
The inverse relation
[tex]f(x) = \frac{1}{5}x - \frac{4}{5}[/tex]
Rewrite as:
[tex]y = \frac{1}{5}x - \frac{4}{5}[/tex]
Swap x and y
[tex]x = \frac{1}{5}y - \frac{4}{5}[/tex]
Multiply through by 5
[tex]5x = y - 4[/tex]
[tex]y = 5x +4[/tex]
Rewrite the new function as:
[tex]y' = 5x + 4[/tex]
In ADEF, f = 610 inches, e = 590 inches and ZE=70°. Find all possible values of ZF,
to the nearest degree.
Answer:
"76°" is the appropriate solution.
Step-by-step explanation:
Please find attachment of the diagram according to the given query.
The given values are:
In ΔDEF,
f = 610 inches
e = 590
∠E = 70°
∠F = ?
By using the law of sines, we get
⇒ [tex]\frac{Sin E}{e} =\frac{Sin F}{f}[/tex]
On substituting the values, we get
⇒ [tex]\frac{Sin70^{\circ}}{590} =\frac{SinF}{610}[/tex]
On applying cross multiplication, we get
⇒ [tex]SinF=\frac{610\times Sin 70^{\circ}}{590}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{61\times 0.95969262}{59}[/tex]
⇒ [tex]=\frac{57.3212499}{59}[/tex]
⇒ [tex]=0.971546608[/tex]
now,
⇒ [tex]F=Sin^{-1}(0.971546608)[/tex]
⇒ [tex]=76^{\circ}[/tex]
For which product or quotient is this expression the simplest form? (image attached)! please help :((
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)
(x-4)/2(x+4)
