Otis is packing two gift boxes in a shipping carton. The rest of the space in the carton will be filled with packing pellets. What is the volume of the space that needs to be filled with packing pellets?
Answer:
[tex]V_3 = 1916in^3[/tex]
Step-by-step explanation:
Given
See attachment for gift items and the shipping carton
Required
Determine the volume of the empty space
First, we calculate the volume of the carton.
[tex]V = LWH[/tex]
From the attachment
L = 16; W =11 and H =13
So:
[tex]V = 16*11*13[/tex]
[tex]V = 2288[/tex]
Next, calculate the volume of the blue wrap
[tex]V = lwh[/tex]
From the attachment
l = 9; w =9 and h =2
So:
[tex]V_1 = 9 * 9 * 2[/tex]
[tex]V_1 = 162[/tex]
Next, calculate the volume of the pink wrap
[tex]V = lwh[/tex]
From the attachment
l = 6; w =5 and h =7
So:
[tex]V_2 = 6*5*7[/tex]
[tex]V_2 = 210[/tex]
The volume of the rest space (V3) is then calculated as:
[tex]V_3 = V - V_1 -V_2[/tex]
[tex]V_3 = 2288 - 162 -210[/tex]
[tex]V_3 = 1916[/tex]
Hence, the rest volume is 1916in^3\
A bricklayer lays 1200 bricks in an average 8-hour day. How many bricks does he lay in a 40-hour week?
The number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.
Let the number of bricks that the bricklayer can lay in a 40-hour week be represented by x.
Based on the information given in the question, the equation to solve the question will be:
8/40 = 1200/x
Cross multiply
8 × x = 1200 × 40
x = (1200 × 40) / 8
x = 1200 × 5
x = 6000
Therefore, the number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

Paula is going to hire a makeup artist for a fashion show and is comparing prices. Shelley charges $40 as a booking fee and an additional $30 per hour. Ezra charges $35 per hour, plus a booking fee of $30. Depending on the length of the show, the cost could end up being the same for either artist. What would the cost be?
Answer:70
Step-by-step explanation:
The cost of booking was $100 as obtained by the length of the show.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
From the given information the two linear equations can be formed as,
30x + 40 and 35x + 30.
The cost would be the same when we'll equate these two equations.
30x + 40 = 35x + 30.
30x - 35x = 30 - 40.
- 5x = - 10.
5x = 10.
x = 10/5.
x = 2, So at two hours the cost would be the same and the total cost is,
$30(2) + 40.
$60 + 40.
= $100.

Steve studies math for 7/8 of an hour and history for 2/3 of an hour. How many hours did he study?
Answer:
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
Step-by-step explanation:
Find a common multiple of the denominators 3 and 8, which would be 24. Convert the fractions:
7/8 x 3/3 = 21/24.
2/3 x 8/8 = 16/24
Add the two numerators = 37/24 or 1 13/24.
1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.
The answer is 1 13/24 hours or 1 hour, 32.5 minutes

6 Work out the sizes of the angles labelled rº, sº and tº.
Plzzzz help I suck at geometry
Answer:
t = 30
s = 25
r = 55
Step-by-step explanation:
Let's begin by r
r is angle in quadlitral shape, so the sum of the interior angles = 360
r = 360 - (95 +100+110) = 55
Then Now it's time for ( t )
Look at the triangle whose angles are r, 95 and t. The sum of the measures of the interior angles of triangle is 180
so t = 180 - ( 95 + r) = 180 - (95 + 55) = 30
Similarly, look at the triangle whose angles are r, s and 100
s = 180 - (100 + r) = 180 - (100 + 55) = 25

Find the slope of the line y = –7 2 x − 5 8 . Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
Slope = -7/2
Step-by-step explanation:
The standard equation of a line is expressed as y = mx+c
m is the slope
c is the y-intercept
Given the equation y = -7/2 x - 5/8
Compare with the general equation
mx = -7/2x
Divide both sides by x
mx/x = -7x/2x
m = -7/2
Hence the slope of the line is -7/2

What the surface area of a rotating prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a Prism = (2 × Base Area) + (Base perimeter × Length).
Here, area of base is Area=2(Base×Height)
= 2(6×4)
= 12 square millimeters
Now, Base perimeter × Length= (5+5+6)×7
= 16×7
= 112 square millimeters
Total area = 12+112

Determine if the three lengths can be the measures of the sides of a triangle.
3 in, 9 in and 8 in
Answer:
yes
Step-by-step explanation:
For the lengths to form a triangle, the sum of any 2 must be greater than the third, that is
3 + 9 = 12 > 8
3 + 8 = 11 > 9
9 + 8 = 17 > 3
Thus the 3 lengths can form a triangle

find the vertex of the quadratic function f(x) = (x-4) (x+2)
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The x- coordinate of the vertex is at the midpoint of the zeros.
Given
f(x) = (x - 4)(x + 2)
Find the zeros by letting f(x) = 0 , that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then
[tex]x_{vertex}[/tex] = [tex]\frac{-2+4}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Substitute x = 1 into f(x) for corresponding y- coordinate
f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9
Vertex = (1, - 9 )
After dinner 1-3 of the corn bread is left suppose 2 friends want to share it equally what fraction names how much of the whole pan of corn bread each f riend will get
Answer:
Each friend will get [tex]\frac{1}{18}[/tex] of whole pan of corn bread
Step-by-step explanation:
As given,
Corn bread left = [tex]\frac{1}{3}[/tex]
Total number of friends = 2
So the left bread will divide into 2 parts
So, each person will get = [tex]\frac{1}{2}[/tex] ( [tex]\frac{1}{3}[/tex] ) = [tex]\frac{1}{6}[/tex] of the left bread
Now,
Left bread = [tex]\frac{1}{3}[/tex] of whole bread
And
Each person get = [tex]\frac{1}{6}[/tex] of the left bread
= [tex]\frac{1}{6}[/tex] ×[tex]\frac{1}{3}[/tex] of whole bread
= [tex]\frac{1}{18}[/tex]of whole bread
∴ we get
Each friend will get [tex]\frac{1}{18}[/tex] of whole pan of corn bread
