The volumes of two similar solids are 729 m^3 and 125m^3. The surface area of a larger solid is 324 m^3. What is the surface area of the smaller solid
Answers
Answer:
100 m^2
Step-by-step explanation:
The scale factor of the volume of solids is the cube of the scale factor of linear dimensions.
The scale factor of the area of solids is the square of the scale factor of the linear dimensions.
Volume scale factor:
125/729 = (5/9)^3
Linear scale factor:
5/9
Area scale factor:
(5/9)^2 = 25/81
Proportion to find the area of the smaller one:
Let the area of the smaller one equal x.
25/81 = x/324
81x = 25 * 324
Divide both sides by 81
x = 25 * 4
x = 100
Answer: 100 m^2

Two points on this line segment partition it in a ratio of 1 : 3 and 3 : 1.
Then, The x coordinates of these two points are 2 and 6
What is a ratio defined?The quantity, amount, or size link between two or more things: proportionRatios are used to compare two numbers by dividing them. If you want to compare one data point (A) to another (B), your formula would be A/B. This signifies that you are dividing data A by data B. If A is five and B is ten, your ratio will be 5/10.A ratio indicates the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).a line segment on a coordinate plane has a slope of 1 and the end points at (1,a) and (9,b).
[tex]\frac{b-a}{9-1} =1 \\b-a = 9[/tex]
Two points on this line segment partition it in a ratio of 1 : 3
9 - 1 = 8
8 * 1/4 =2
8*3/4 = 6

What is the sum of the angles in a right triangle?The sum of the angles in a right triangle must be 180 degrees.
We have,
In right-triangle PQR
PQ is perpendicular to QR.
So,
∠PQR = 90 degrees.
∠QPR = ∠QRP = 45 degrees.
We see that,
QS is perpendicular to PR
So,
∠QSP = b = 90 degrees
∠QSR = c = 90 degrees
Now,
From right-triangle QSP and right-triangle QSR.
We have,
QSP = b = 90 degrees
QPS = a = 45 degrees
QSR = c = 90 degrees
QRS = d = 45 degrees
Find a + b + c + d.
= 45 + 90 + 90 + 45
= 270 degrees
Thus the correct answer is 270°
a + b + c + d = 270°

What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.?
Use 3.14 to approximate pi, and express your final answer to the nearest hundredth.
Answers
Answer:
1017.88
Step-by-step explanation:
The volume of a cone is V=1/3hπr²
First, we are going to do exponents: what is 9*9? 81. So now our equation is V= 1/3h * 3.14 * 81 (Pi is 3.14, so we filled that in too.)
Now we need to find 1/3 of our height, or 1/3 * 12, which is 4. Our equation is now V= 4 * 3.14 * 81
Solve and you get 1017.88

The mixed number can be written as an improper fraction of 44/5 after simplifying the answer is 44/5.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The mixed number is 8 4/5
To write the mixed number as an improper fraction:
= 8 + 4/5
Take LCM as 5
LCM can be defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
= (8x5 + 4)/5
= (40 + 4)/5
= 44/5

Answer:
Answer choice A. Slope -1

If we plot the two points on a graph we can see that the points go from left to right, starting from a higher point to a lower point. This means the slope is negative. B and D are the same choice, but just in different words, and 0 cannot be positive or negative. and C is positive, not negative. So it is A.

Which line is perpendicular to the line shown on the graph Map testing
Answers
Answer:
Step-by-step explanation:
Since the graph with the line isn't provided, I can only tell/show you how to find the perpendicular line.
When two lines a perpendicular, they can have different y-intercepts. But the slope of line will change to it's reciprocal.
So if you have a line that is y = 2x + 7 the perpendicular line would be,
y = -1/2 x + 7
