The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere?
Answers
The approximate volume of the sphere is 266.19 cubic centimeters.
To find the approximate volume of a sphere from its surface area, we will use the relationship between the surface area and radius of the sphere and then apply the formula for the volume. The surface area (A) of a sphere is given by the formula A = 4πr2, and the volume (V) is given by the formula V = (4/3)πr3. Given that the surface area of the sphere is 200.96 square centimeters, we can solve for the radius (r) first:
A = 4πr2
=> r2 = A / (4π)
=> r2 = 200.96 / (4π)
=> r = √(200.96 / (4π))
=> r ≈ 3.99 cm (after calculating using a calculator)
Now that we have the radius, we can find the volume:
V = (4/3)πr3
=> V = (4/3)π(3.99 cm)3
=> V ≈ 266.19 cm3 (after calculating using a calculator)
Therefore, the approximate volume of the sphere is 266.19 cubic centimeters.

m∠2=m∠1
m∠2=105°
m∠1=75°
m∠3=m∠1
Answers
The second one is wrong.
the third one is right.
The forth one is wrong.
180 - 105 = 75°
∠1 = 75°
∠1 and ∠2 are corresponding angles, and so there measurements will be the same
∠1 = ∠2
∠1 = 75°
∠2 = 75°
105° and ∠3 are same side, and are corresponding angles. Therefore, ∠3 = 105°
m∠1=75°
180° (the measurement of a straight angle).
Subtract the 105° (given) from the straight angle
180 - 105 = 75
m∠1=75°

Javier and Kyle work installing windows and can earn extra money by installing doors. Last week, Javier earned $56 more than Kyle because of door installations. The expression below represents Javier's pay for the week: 14w + 56 What does the first term of the expression represent?
Answers
The expression below represents Javier's pay for the week: 14w + 56
As it states in the question Javier earned $56 more than Kyle because of door installations. Therefore, the $56 in the equation would represent the door installation.
The 14w would represent the amount of windows that have been installed.
Answer:
[tex]14w[/tex] represents Kyle's pay for the week.
Step-by-step explanation:
"Javier earned $56 more than Kyle because of door installations"
In other words, this means if we take out 56 from Javier's total amount of pay, we get what Kyle earned last week.
Javier's pay is [tex]14w+56[/tex] , so if we subtract 56 from this expression we will get what Kyle earned last week.
[tex]14w+56-56=14w[/tex]
So, the first term of the expression 14w + 56, which is 14w, represents earnings of Kyle last week.
Delia measured a doorway to be 1 meter wide. Which of these is a nearly equivalent measurement
A: 15 mi
B: 10.5 yrds
C: 3.3 ft
D: 98.7 in
Answers
To find a nearly equivalent measurement to 1 meter wide, the correct answer is C: 3.3 feet, as it is very close to 39.37 inches, the length of 1 meter in inches.
Explanation:To find a nearly equivalent measurement, we can examine the conversion between meters and other units of length. Based on the provided information, 1 meter is equivalent to 1.094 yards or 39.37 inches.
When comparing the options given:
15 miles (mi) is much larger than a meter and, therefore, not equivalent.10.5 yards (yrds) is significantly more than 1 meter, so it is not a close match either.3.3 feet (ft) can be checked by knowing that there are 12 inches in a foot, which would be equivalent to 39.6 inches, making this measurement very close to 1 meter.98.7 inches (in) would be more than twice the length of 1 meter since we know 1 meter is about 39.37 inches.Therefore, the answer that is nearly equivalent to 1 meter is C: 3.3 feet.
This is because 3.3 feet, when converted to inches (3.3 ft x 12 in/ft), is approximately 39.6 inches, which is very close to the 39.37 inches that make up 1 meter.
Final answer:
The most nearly equivalent measurement to 1 meter wide, among the provided options, is 98.7 inches (option D), as 1 meter equals approximately 39.37 inches.
Explanation:
Delia measured a doorway to be 1 meter wide. To find a nearly equivalent measurement in a different unit, we must look at the options provided and use unit conversion reference information:
1 m = 1.094 yd = 39.37 inches1 in. = 2.54 cmComparing the given options against the meter measurement:
A: 15 mi – This is substantially larger than a meter.B: 10.5 yrds – This is also considerably larger than a meter.C: 3.3 ft – This is approximately 1 meter since 1 yard (3 feet) is slightly less than a meter (1 m = 1.094 yd).D: 98.7 in – This is close to a meter (1 m = 39.37 inches).Thus, the most nearly equivalent measurement to 1 meter wide is option D: 98.7 inches.

FIND VOLUME
60 is the area of the base
Answers
First of all, V (prism) = area of base (B) × h
We know that the height (h) of this prism is given, which we'll need later on: h = 5 ft, and area of base (B) is given as 60 ft2
So V = 60 ft2 × 5 ft = 300 ft3
So now for the hard part... how to calculate the SA of this prism
IF YOU DON'T NEED SA FOR THIS TYPE OF PROBLEM, DO NOT PROCEED!!!
[VERY DETAILED]
means solving the dimensions (sides) of that pesky polygon base (B) or lid.
The most important things about polygons are:
1) is it regular (same angle ° and side length)??
2) How many sides or angles??
This has to be regular, because they give you no other info so it has to be, in order to solve. And then it has 5 sides and angles = regular pentagon. ("penta" means 5).
Now there are 360° in any circle, so:
take the central angles of where the sides meet at the center forming triangles (see drawing above), each of those (5) central <'s = 360/5 = 72°
Now the apex of each of these triangles = 72°
but with our 5 triangles, we need to find the height of each triangle -- which is the midpoint of the side (base (b) of triangle), and h is perpendicular to this b. By bisecting that apex angle of 72, it forms 2 equal right triangles of
72/2 = 36°. So each right triangle has 36, 90, and?? 180-36-90 = 90-36 = 54°
let's call the base (b) = 1 side of pentagon
= side (s)
Therefore (see 2nd image drawn above) tangent (tan) of € = opposite/adjacent, or
tan (54) = h÷1/2b --> h = [tan (54)]×(1/2)b
1/2b = h/[tan (54)] = h/1.38
Also the area of each of the larger 5 triangles A(t) = 1/2b×h, and that area A(t) × 5 = area of whole pentagon base A(B)
So now after all that... our A(B) given at beginning = 60ft2. let's put it all together:
1/2b = h/[tan (54)] = h/1.38
A(t) = 1/2b×h, and A(B) = 5×A(t)
which means that A(B) = 5×(1/2b×h)
AND since the other calculation shows that 1/2b = h/1.38, plug that value into the A(B) formula...
.
.
.
now that we have height (h) of each triangle, we can go back to our tan equation for the triangle: tan (54) = 1.38 = h/(1/2b)
--> 1/2×b = h/1.38 --> base (b) = 2h/1.38
b = 2(4.06 ft)/1.38 = 8.12 ft/1.38 = 5.90 ft, for which b us also the width of each rectangular side panel (w)
length (l) of these sides was given as height of the whole prism = 5 ft
NOW FINALLY... THE FINAL SURFACE AREA OF THE PRISM (SA) = (2×A(B)) + (5×rectangular side)
SA = (2×60 ft2) + (5×(l×w)) = 120 ft2 + 5×5ft×5.9ft
SA = 120 ft2 + 147.62 ft2 = 267.62 ft2

Banks generally do not charge the same interest rate on new and used cars. Factors including the type of car, borrower's credit history, length of the loan, and market conditions can affect the interest rate. Usually, used cars have higher interest rates due to higher perceived risk.
Explanation:No, banks do not always charge the same interest rate on new and used cars. Interest rates are based on numerous factors that include the type of car (new or used), the borrower's credit history, the length of the loan, and the existing market conditions. Typically, used cars have higher interest rates because they are viewed by the bank as more risky investments. Therefore, individuals with excellent credit may secure lower interest rates on both new and used car loans, but the rate for used cars will still generally be higher than for new cars.

It takes a ship 4 hours to cover 420 km with the current and 6 hours against the current. Find the speed of the ship in still water and the speed of the current.
Answers
We know that distance equals speed multiplied by the time.
With the current
[tex]\left(s+c\right)\left(4\:hours\right)=420\:km[/tex]
or
[tex]s+c=105[/tex]
This is our first equation.
Now, against the current, we have
[tex]\left(s-c\right)\left(6\right)=420[/tex]
or
[tex]s-c=70[/tex]
This is our second equation.
We solve the equations simultaneously, by adding them together
[tex]2s-0c=175[/tex]
[tex]s=87.5\:km/hr[/tex]
Substitute s=87.5 to the first equation to solve for c.
[tex]87.5+c=105[/tex]
[tex]c=17.5\:km/hr[/tex]
The speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.
The speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.
What is the speed of the current?The actual propagation speed depends on the size of the wire and electrical parameters such as its inductance, but it is normally approximately 90% of the speed of light—about 270,000 km/s.
Let x be the speed of the ship, and y be the speed of the current.
It takes a ship 4 hours to cover 420 km with the current and 6 hours against the current.
[tex]\rm (x+y)4=420\\\\x+y=\dfrac{420}{4}\\\\x+y=105[/tex]
And the second equation is;
[tex]\rm (x-y)6=420\\\\x-y=\dfrac{420}{6}\\\\x-y=70[/tex]
Adding both the equation
[tex]\rm x+y+x-y=105+70\\\\2x=175\\\\x=\dfrac{175}{2}\\\\x=87.5[/tex]
Substitute the value of x in equation 1
[tex]\rm x+y=105\\\\87.5 +y=105\\\\y=105-87.5 \\\\y= 17.5[/tex]
Hence, the speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.

The English Alphabet has 20 letters more than one-fourth the number of letters in the Greek Alphabet. The English Alphabet has 26 letters. Which of the following equations would you use to find the number of letters, g, in the Greek Alphabet?
Answers
Greek Alphabet = g
The English Alphabet has 20 letters more than one-fourth the numbers of letters in the greek alphabet: 1/4g + 20 = e

Isolate the g, do the opposite of PEMDAS. Note the equal sign. What you do to one side you do to the other.
Subtract 20 from both sides
1/4g + 20 (-20) = 26 (-20)
1/4g = 26 - 20
1/4g = 4
Multiply 4 to both sides to isolate the g
