The equatorial diameter of a model of earth is 25.6 cm. What is the total surface area of the model
Answer:
[tex]2059.7\,\,cm^2[/tex]
Step-by-step explanation:
Diameter of a model of earth (D) = 25.6 cm
Radius of a model of earth (r) = [tex]\frac{D}{2}=\frac{25.6}{2}=12.8\,\,cm[/tex]
Earth has the shape of a sphere.
Total surface area of a sphere = [tex]4\pi r^2[/tex]
Put [tex]\pi=\frac{22}{7}\,,\,r=12.8\,\,cm[/tex]
So,
Total surface area of the model [tex]=4(\frac{22}{7})(12.8)^2=2059.7\,\,cm^2[/tex]
PLEASE HELP!!!!!!!!!!!!
Step-by-step explanation:
The shaded part of the curve with interval 0 <= x <= 1 is not the whole curve.
The point of the curve that is furthest to the left has x-value -5.
The point of the curve that is furthest to the right has x-value 3.
Hence the correct domain is -5 <= x <= 3.
I would like if someone can explain the steps for this please

Find the solution of the system of equations.
−3x+8y=11
−3x−5y= −41
Answer:
Step-by-step explanation:
Subtract the equations. We get
13y = 52
y=4
SUBSTITUTE y in 1st equation and find x
-3x+8(4) =11
-3x = 11-32
-3x = -21

Miles has a train collection with 36 engines, 72 boxcars, and 18 cabooses. He wants to arrange the train cars in equal rows with only one type of train car in each row. How many can he put in each row? Mark 4 that apply.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Number of engines = 36
Number of car boxes = 72
Number of cabooses = 18
To areange in equal rows :
We need to obtain the greatest common factor :
Factors of :
36 : 2, 3, 4, 6, 9, 12, 18, 36
18 : 2, 3, 6, 9, 18
72 : 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The greatest common factor (GCF) is 18
Number that can be put in each row :
Cabooses :
18 / GCF = 18 / 18 1 row
Engines :
36 / GCF = 36 /18 = 2 rows
Box cars :
72 / GCF = 72 / 18 = 4 rows

Solve the equation. 5t^3 +40t^2 = -80t
a. t= 0 and t= 4
b. t= -4 and t=0
c. t= -4 and t= 5
d. t= 4
Answer:
Option 'A' is true.
Step-by-step explanation:
Given the equation
[tex]5t^3\:+40t^2\:=\:-80t[/tex]
Add 80 to both sides
[tex]5t^3+40t^2+80t=-80t+80t[/tex]
Simplify
[tex]5t^3+40t^2+80t=0[/tex]
as 5t³ + 40t² + 80t = 5t (t + 4)²
5t (t + 4)² = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]t=0[/tex] or [tex]t+4=0[/tex]
solving
[tex]t + 4 = 0[/tex]
subtract 4 from both sides
[tex]t+4-4=0-4[/tex]
Simplify
[tex]t=-4[/tex]
Therefore, the solution to the equation is:
[tex]t=0,\:t=-4[/tex]
Hence, option 'A' is true.

5. A train travelled 720 km in 9 h. How far
would it travel in 11 h?
Answer:
The train would travel 880 km in 11 hours.
Step-by-step explanation:
Answer:
880 km
Step-by-step explanation:
To get from 9 to 11, we multiply 9 by 11/9, so the same must be done to 720 km to get the amount in 11 hours. 720 * 11/9 is equal to 880, so the train travels 880 km in 11 hours.
Which event has a probability of 0?
A. Flipping heads on a coin
And rolling a 4 on a 6 sided number cube
B. Rolling an odd, then an even number on a 6-sided number cube
C. Drawing two vowels (without replacing them) from the word MATH
D. Flipping tails on a coin 3 times in a row
Answer:
C
Step-by-step explanation:
There is only one vowel in the word MATH so it's impossible to draw two vowels without replacing them

Is the graphed function linear?
Yes, because each input value corresponds to exactly one output value.
Yes, because the outputs increase as the inputs increase.
No, because the graph is not continuous.
No, because the curve indicates that the rate of change is not constant.
Answer:
The answer is D. No, because the curve indicates that the rate of change is not constant.
Step-by-step explanation:
There is not a constant rate of change which results in a curved line.
Answer:
It is the last one: No, because the curve indicates that the rate of change is not constant.
Step-by-step explanation:
You can tell in the picture that if you connected the points it would not create a straight line.
Describe the likelihood of an event as impossible, unlikely, equally likely, likely or certain. 21) There is a 0% chance of picking a 13 in a deck of cards. _________________ 22) There is a 50% chance of picking a red card in a deck of cards. _______________ 23) There is an 80% chance of snow tomorrow. _________________ 24) There is a 20% chance of rain tomorrow. _________________
Answer:
21) There is a 0% chance of picking a 13 in a deck of cards. Impossible.
If there is a 0% chance that something will happen then it is impossible.
22) There is a 50% chance of picking a red card in a deck of cards. Equally likely.
If there is a 50% chance that something will happen, it is equally likely that it will happen.
23) There is an 80% chance of snow tomorrow. Likely or certain.
If there is an 80% chance of something happening, it means that the chances of that thing happening good and the event is likely to occur.
24) There is a 20% chance of rain tomorrow. Unlikely.
A low chance of 20% means that something is unlikely to occur.

HELP FIND THE UNIT RATE OF 90 DAYS/20 TRIPS PLEASEEEEE
Answer:
The unit rate is 4.5 days per trip
Step-by-step explanation:
So the equation would be 90 divided by 20
Simplified it is the same thing as 9 divided by 2
90 divided by 20 is 4.5
Answer:
4.5/1
Step-by-step explanation:
First, I found that 10 was the first factor or whatever I could find, so our new ratio is:
9/2
This is obviously not the unit rate, but if we divide by 2 we get:
4.5/1
So our unit rate is 4.5/1

In 1990, the value of a home is $170,000. Since then, its value has increased 5% per year.
What is the approximate value of the home in the year 1993?
Answer:
195.500
Step-by-step explanation:
5 percent of 170,000 is 8,500.
Since 3 years pass we're multiplying 8,500 by 3.
8,500
x 3
_____
25,500
Now we just add 170,000 + 25,500, and we get 195.500.
