Lateral Area = No lateral area (choice D)Surface Area = 25.97 square inches (choice E)Volume = 12.44 cubic inches (choice A)============================================
Explanation:
Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.
-----------------------
The radius is 1 & 7/16
Let's convert this to decimal form
1 & 7/16 = 1 + (7/16)
1 & 7/16 = 1 + 0.4375
1 & 7/16 = 1.4375
The radius is r = 1.4375 inches.
-----------------------
SA = Surface area the sphere
SA = 4*pi*r^2
SA = 4*pi*(1.4375)^2
SA = 25.9672267773281
SA = 25.97 square inches (choice E)
-----------------------
V = Volume of the sphere
V = (4/3)*pi*r^3
V = (4/3)*pi*(1.4375)^3
V = 12.4426294974698
V = 12.44 cubic inches (choice A)
what is the percent of change from 800 to 40?
Answer:
95%
Step-by-step explanation:
%Change from 800 to 40 = %Decrease
%Decrease = Old Value - New Value/Old Value × 100%
%Decrease = 800-40/800 × 100%
%Decrease = 760/800 × 100%
% Decrease = 95%(Answer)
According to an accepted chemistry reference, the
heat of vaporization of water is 540 calories per
gram. A student determined in the laboratory that
the heat of vaporization of water was 620 calories
per gram. The student's results had a percent error
of
Answer:
14.8%
Step-by-step explanation:
Step 1: Given data
True value for the heat of vaporization of water (ΔH°vap(T)): 540 cal/g
Experimental value for the heat of vaporization of water (ΔH°vap(E)): 620 cal/g
Step 2: Calculate the experimental percent error
To determine the experimental percent error we will use the following expression.
%E = |ΔH°vap(T) - ΔH°vap(E)|/ΔH°vap(T) × 100%
%E = |540 cal/g - 620 cal/g|/540 cal/g × 100%
%E = 14.8%

Answer:
2[tex]\frac{1}{3}[/tex]inches
Step-by-step explanation:
First, I would try to get the mixed numbers into improper fractions. Then, I try to make them have the same denominator so it is easier.
1[tex]\frac{1}{2}[/tex]feet --- 2 inches
[tex]\frac{3}{2}[/tex]feet --- 2 inches

Find all values of X which make the equation below true | 3x + 5 | = 8
Answer:
x= -13/1,1
3x+5=8
-(3x+5)=8
x=1
x=-13/3
x=-13/3,1
Answer:
x and equal 1 or -13/3
Step-by-step explanation:
this is an absolute value equation so the equation can either equal 8 or -8. if you set up two equations that are 3x+5=8 and 3x+5 = -8 and just isolate the x, you get 1 and -13/3.

How will you graph the function g(x) = (x – 4)+ 12 using the parent quadratic function, f (x) = x2?
9514 1404 393
Answer:
see below
Step-by-step explanation:
We assume your functions are ...
f(x) = x²
g(x) = (x -4)² +12
_____
You need to be able to recognize that g(x) matches a pattern:
g(x) = f(x-h) +k
where h = 4, and k = 12.
In this pattern, the value of h is the number of units the graph is translated to the right. The value of k is the number of units the graph is translated up.
So, g(x) is the same as the graph of f(x), but translated 4 units right and 12 units up.

Answer:
PN = 10
Step-by-step explanation:
Base angles converse theorem states that a triangle with two congruent angles is isosceles. The sides opposite to the two congruent angles are the congruent sides. The side between the two congruent angles is the base.
In this problem, it is given that <P = <O, hence ΔNOP is isosceles, because of base angles theorem. OP is the base, and hence NO is one of the congruent sides and therefore has to be congruent to PN. Which means that PN is 10.

A rectangular swimming pool is 6 ft deep. One side of the pool is 2.5 times longer than the other. The amount of water needed to fill the swimming pool is 2940 cubic feet. Find the dimensions of the pool.
The smaller dimension of the pool is __ ft.
The larger dimension of the pool is __ ft.
Answer:
The smaller dimension of the pool is 14 ft.
The larger dimension of the pool is 35 ft.
Step-by-step explanation:
We are told that:
The rectangular swimming pool is 6 ft deep. Thus, depth: h = 6 ft
One side of the pool is 2.5 times longer than the other.
Thus, length = 2.5(width)
l = 2.5w and width = w
Volume; V = lwh = (2.5w × w × 6) = 15w²
The amount of water needed to fill the swimming pool is 2940 cubic feet.
Thus;
15w² = 2940
w² = 2940/15
w² = 196
w = √196
w = 14 ft
Length: L = 2.5w = 2.5 × 14 = 35 ft

Michelle and her roommate rent an apartment for $798 a month. Each of them pays half. Because there are about 4 weeks in a month, Michelle estimates her share of the rent is about $100 a week. Is that a good estimate?
Yes
No, it is much high
Not, it is much low
Answer:
yes
Step-by-step explanation:
half of $798 is $399. $100 a week × 4 = $400. 400 is very close to 399, so yes it would be a food estimate. Hope this helps! :)
Monica went shopping for holiday presents. She bought boxes of chocolates and boxes of ornaments for her
coworkers. Boxes of chocolate cost $10 each and boxes of ornaments cost $12 each. She buys a total of 14
boxes and spends $156. How many boxes of chocolates and how many boxes of ornaments does she buy?
Use C for number of chocolate boxes and for number of ornament boxes.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The number of chocolate boxes is 6.
The number of ornament boxes is 8.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 5 is an equation.
We have,
Number of chocolate boxes = C
Number of ornaments boxes = B
The total cost of 14 boxes = $156
Cost of one box of chocolate = $10
Cost of one box of ornaments = $!2
Now,
C + B = 14 ______(1)
10C + 12B = 156 _______(2)
From (1) we get,
C = 14 - B ______(3)
Putting (3) in (2) we get,
10 (14 - B) + 12B = 156
140 - 10B + 12B = 156
140 + 2B = 156
2B = 156 - 140
2B = 16
B = 16/2
B = 8
Now,
C = 14 - B
C = 14 - 8
C = 6
Thus,
The number of chocolate boxes is 6.
The number of ornament boxes is 8.

Answer:
Option B. f¯¹(x) = ³√(– x – 9)
Step-by-step explanation:
From the question given above:
f(x) = – x³ – 9
f¯¹(x) =?
We can obtain the inverse f¯¹(x) of the above equation by doing the following:
f(x) = – x³ – 9
Replace f(x) with y
y = – x³ – 9
Interchange x and y
x = – y³ – 9
Make y the subject . This is illustrated below:
x = – y³ – 9
Rearrange
x + 9 = – y³
Multiply through by –1
–(x + 9) = y³
y³ = – x – 9
Take the cube root of both side
y = ³√(– x – 9)
Replace y with f¯¹(x)
f¯¹(x) = ³√(– x – 9)
Thus, the inverse of the function
f(x) = – x³ – 9
is
f¯¹(x) = ³√(– x – 9)

the length of a rectangular sing is 5 time its width. if the sign perimeter is 24 inches. what is the sign area ?
Answer:
20 in²
Step-by-step explanation:
Assuming that the width of the sign is x, then from the question, we're told that the length is 5 times it's width, so
b = x inches
l = 5x inches
Again, we're told that the perimeter of the sign is 24 inches, and we know already that the perimeter of a rectangle is given as
Perimeter = 2(l + b), substituting this, we have
24 = 2(5x + x)
24 = 10x + 2x
24 = 12x
x = 24 / 12
x = 2 inches.
Since x is the width of the rectangle, and it's 2 inches, we use it to find the length of the sign.
l = 5 * 2
l = 10 inches.
Then, we are asked to find the area of the sign. Area of a rectangle is given as
A = l * b, so if we substitute, we have
Area = 10 * 2
Area = 20 square inches
