A cone has a diameter of 10 inches and a depth of 20 inches. If you use the formula V=13πr2h to find the volume, will your answer be ≈523.6 inches3?
Please help
Answer:
Yes, the answer would be 523.6
Step-by-step explanation:
Formula for Volume of a cone:
V = πr²(h/3)
r = d/2
10/2
r = 5
V = πr²(h/3)
V = π(5²)(20/3)
V = π(25)(20/3)
V = 523.6

Answer:
Blank 1: y=3x+10
Blank 2: y= 40
Step-by-step explanation:
Let the cost of gift wrap be y and the number of gifts be x.
Department
An upfront fee of $10 means that Mr Bentley needs to pay $10 first, and this $10 is only paid once on top of the cost of wrapping each gift.
y= 3x +10
Niece
A flat fee of $40 means that no matter how many gifts the niece wraps, Mr Bentley only pays $40.
y= 40
To find out when the two plans cost the same, equate the two equations together. Then, solve for x.
3x +10= 40
3x= 40 -10 (-10 on both sides)
3x= 30
x= 30 ÷3
x= 10
Thus when Mr Bentley has 10 gifts to be wrapped, the 2 plans costs the same.

Answer: The answer is D (Mr. Johnson will earn $140 for 12 hours of work
Step-by-step explanation:
So with process of elimination we can safely say that for every hour Mr. Johnson will earn 12$.
So it is true that *A* e(amount earned)= 12h($12 made per hour)
And if *B* Mr. Johnson makes $12 per hour then in 4.5 hours he will make $54
We also know for a fact *C* Mr.Johnson earns $12 per hour
but in 12 hours Mr. Johnson will make $144 not $140 so *D* is incorrect
Nicole washed 4/10 of a bag of potatoes.She left the rest in a basket outside what amount of potatoes did Nicole leave outside?
Answer:
6/10 Simplified: 3/5 of a bag
Step-by-step explanation:
One bag= 10/10
She washed 4/10
So, 10/10-4/10=6/10
6/10=3/5
3/5 of a bag

The triangles are congruent by SSS or HL.
Triangles M N Q and P Q N are connected at side Q N. Triangle M N Q is rotated about point N and then is shifted to the left to form triangle P Q N.
Which transformation(s) can map TriangleMNQ onto TrianglePQN?
translation only
reflection only
rotation, then reflection
rotation, then translation
Answer:
rotation, then translation
Step-by-step explanation:
The transformation that map triangle MNQ onto triangle PQN is rotation, then translation.
The given triangles;
Triangle MNQ Triangle PQNA translation of a triangle occurs when the triangle shifts up, or down, of left or right on the coordinate plane.
The reflection of a triangle occurs when the vertices of the triangle is flipped over the opposite side.
Since the triangle MNQ is rotated then shifted to the left to form the new triangle PQN, we can conclude that the transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

A quadrilateral has two angles that measure 290° and 20°. The other two angles are in a
ratio of 2:3. What are the measures of those two angles?
Answer:
Step-by-step explanation:
The remains two angles are 2x and 3x.
2x+3x = 360-290-20 = 50°
x= 10°
One angle is 20°. The last angle is 30°

Answer:15
Step-by-step explanation:
put the quadratic into vertex form and state the coordinates of the vertex
y = x² + 6x - 41
Answer:
The vertex form of the quadratic: y = (x - 1)² + 2
Coordinates of vertex: (1, 2)
Step-by-step explanation:
The vertex form of an equation of the parabola is: f(x) = a(x - h)² + k
where (h, k) is the vertex. So:
x - h = x - 1 ⇒ h = 1
+ k = +2 ⇒ k = 2 -------------------------------------------------------------------------------

Stephanie puts 30 cubes in a box. The cubes are inch on each side. The box holds 2 layers
with 15 cubes in each layer. What is the volume of the box?
Answer:
[tex] 11.25\: {in}^{3} [/tex]
Step-by-step explanation:
Since, box contains two layers of cubes and each layer has 15 cubes.
So, length = 15*1/2 in = 7.5 in,
width = 3*1/2 in = 1.5 in
height = (1/2 + 1/2) = 1 inch
Volume of box = lbh
= 7.5* 1.5 *1
= 11.25 cubic inches

Factorise this pleasee
Answer:
x(x-2)
Step-by-step explanation:
the common multiple here is the x, notice how it appears in both both terms. thus, we can factor it out of the equation going from x²-2x to x(x-2)
x(x-2)
Im assuming you meant x² - 2x but correct me if i'm wrong!
so x is common in both terms so you can take it out and factorise it.
