Squares of side A are cut from each corner of a 8 in x 6 in rectangle so that its sides can be folded to make a box with no top.Represent a function in of a that can define the volume of the box.
A rectangle measuring 8 inches by 6 inches needs squares of side. A function in an in which the box's volume is 4a³-28a²+48a.
Given that,
A square measuring 8 inches by 6 inches needs squares of side. A cut out of each corner so that the sides can be folded into a box without a top.
How much area a box can occupy is determined by its volume. You need to know a box's length, width, and height in order to compute its volume. By multiplying the base area by the box's height, one can get the volume of a box.
The measurement of how much space an object may occupy is called volume, which is also known as capacity. Both regular and irregular objects may be present. Cubes, blocks, cylinders, pyramids, cones, and spheres are examples of common objects.
A: area of the base
L: Length of the base
W: Width of the base
V(a)= (8-2a) (6-2a) (a)
V(a)= (48-16a-12a+4a²) (a)
V(a)= (48-28a+4a²) (a)
V(a)= 48a-28a²+4a³
V(a)=4a³-28a²+48a
Therefore, a function in an in which the box's volume is 4a³-28a²+48a.

Answer:
X = 36.5
Z = 19
Angle RIG is 69
angle ZIM is 126.5
Step-by-step explanation:
angle AIZ and ZIP
x + 3x - 56 = 90
4x - 56 = 90
4x = 90 + 56
4x/4 = 146/4
x = 36.5
Plugin the value of x in (3x -56)
3x - 56
(3(36.5) - 56)
(109.5 - 56) = 53.5
Angle AIZ = 53.5
Angle RIG is 4z + 7. Convert the letter x in (x + 2) to Z and solve for z
4z + 7 + z + 2 = 90
5z + 9 = 90
5z = 90 - 9
5z/5 = 81/5
z = 16.2
Z + 2
16.2 + 2 = 18.2
Angle GIM is 18.2 degrees
Plugin the the value of z into 4z + 7 for angle RIG
4z + 7
(4(16.2) + 7) = 71.8
Angle RIG = 71.8 degrees

A) In one hour Graham drove 33 3/4 miles
B) To drive one mile Grahman will take 4/127 hours
a) change into improper fractions

1 1/3 = 4/3
he takes 4/3 hours to drive 127/3 miles
in one hour he will drive 127/3 × 3/4 = 127/4 = 33 3/4 miles
So in 1 hour he will drive 33 3/4 miles
b) he covers 127/3 miles in 4/3 hours
to cover 1 mile he will take = 4/3 × 3/127 = 4/127 hours

anne and nanny use a metal alloy that is 16% copper to make jewelry how many ounces of an alloy that is 10% copper must be mixed with an alloy that is 20% copper to form 55 ounces of the desired alloy
By solving a system of equations we conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.
How many ounces of each alloy should they use?
First, let's define the variables we will use to solve this problem:
x = ounces of the 10% alloy copper they need to use.y = ounces of the 20% alloy copper they need to use.We know that they want to get 55 ounces, then:
x + y = 55
And the concentration of these 55 ounces must be 16%, then we can write other equation:
0.1*x + 0.2*y = 0.16*55
Then we have a system of equations:
x + y = 55
0.1*x + 0.2*y = 0.16*55
Isolating x on the first equation we get:
x = 55 - y
Now we can replace that in the other equation so we get:
0.1*(55 - y) + 0.2*y = 0.16*55 = 8.8
Now we can solve this for y.
5.5 - 0.1*y + 0.2*y = 8.8
5.5 + 0.1*y = 8.8
y = (8.8 - 5.5)/0.1 = 33
Then the value of x is:
x = 55 - y = 55 - 33 = 22
We conclude that they need to use 22 ounces of the 10% alloy and 33 ounces of the 20% alloy.

To the nearest tenth of a meter, what is the distance d from the top of the platform to the beach ball?
the distance, d from the top of the platform to the beach ball is equal to 10.29 m.
We are given that:
Height of the platform = 5 m
distance between bas of the platform and the beach = 9 m
We need to find the distance from the top of the platform to the beach ball.
We know that this distance d will be the hypotenuse of the triangle formed.
So, we have:
Perpendicular = 5 m
Base = 9 m
Hypotenuse = d
So, by using the Pythagoras theorem, we get that:
d² = 5² + 9²
d² = 25 + 81
d² = 106
d = √ 106
d = 10.29 m.
