Answer:
9203 cm³
Step-by-step explanation:
A globe of the moon has a radius of 13 centimeters. Find the volume of the globe. Round your answer to the nearest whole number.
The shape of the moon is spherical
Hence:
The volume of a sphere
= 4/3 × π × r³
r = radius = 13 cm
= 4/3 × π × 13³
= 9202.77 cm³
Approximately to the nearest whole number = 9203 cm³
Therefore, the volume of the globe is 9203 cm³

Step-by-step explanation:
Adia is placing soil in flower pots. She has 58 quart of soil. She needs 54 quarts of soil to fill one whole flower pot. Use the drop-down menus to complete the statements below about the flower pots that Adia can fill with the soil she has.
Answer:
1 whole flower pot
Step-by-step explanation:
Given that:
Quart of soil Adia has = 58
Quart of soil to fill a whole flower pot = 54
The pot Adia can fill. With the soil he has :
Quart of soil Adia has / Quart of soil to fill a whole flower pot
= 58 / 54
= 1.074 pots
= 1 flower pot

Which statement below is correct for the following set of ordered pairs?
{(0,1.2),(3,2),(-1.2,3), (4, -2),(1,-1.2),(1,2,4)}
A. The set is a function since each element in the domain has a different element in the range.
B. The set is a function since each element in the range has a different element in the domain.
C. The set is a not a function since each element in the domain has a different element in the range.
D. The set is a not function since each element in the range has a different element in the domain.
Answer:
C
Step-by-step explanation:
A function can not have the same x-values but can have the same y-values.
If this helps you, please mark as brainliest
The set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a set of ordered pairs:
{(0,1.2),(3,2),(-1.2,3), (4, -2),(1,-1.2),(1,2,4)}
We know there are four main types of mapping that are:
One to one, one to many, many to one, and many to many.
In the case of one to one, and many to one. the relation is a function but in the case of one to many and many to many relations is not a function.
As we can see in the set of ordered pairs the x values are repeated which is also not a property of a function hence it is not representing the function.
Thus, the set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

Here Is a trapozhum and a squnro, The lengths of the parnllel sides of the
trapezhum are 10 cm and 14 cm, The helght of tho trhpoziurm is 12 cm. The nren of
the squpre is equal to the aren of the trapeziurn. Work out the perimeter of the
square
Answer:
48 cm
Step-by-step explanation:
Here Is a trapezium and a square, The lengths of the parallel sides of the trapezium are 10 cm and 14 cm, The height of the trapezium is 12 cm. The area of the square is equal to the area of the trapezium. Work out the perimeter of the square.
Solution:
The area of the trapezium is given by:
A = (1/2)(a + b)h
where h is the height of the trapezium = 12 cm, a and b are the parallel sides. Given that a = 10 cm, b = 14 cm, hence:
A = (1/2)(10 + 14)12 = 144 cm²
Area of trapezium = Area of square
Area of square = 144 cm²
Area of square = length * length = length²
length² = 144 cm²
length = √144 = 12 cm
Perimeter = 4 * length = 4 * 12 cm = 48 cm

Step-by-step explanation:

Answer:
D. x = 10, m<TRS = 60
Step-by-step explanation:
1. Approach
To solve this problem, one will set up an equation to model the problem. The problem gives that the sum of two angles (m<QRT and m<TRS) equals the third angle (m<QRS). Additionally, the measure of one of the angles is given (m<QRS = 122), and the expression for the values of the other two angles are given, (m<QRT = 7x - 8), (m<TRS = 6x). One can form an equation, and solve it to find the unknown. Finally, one can then substitute the values of the unknown, into the expression to find the measure of the angle.
2. Solve for (x)
One can set up an equation based on the given information, then solve the equation.
m<QRT + m<TRS = m<QRS
Substitute,
(7x - 8) + (6x) = 122
Simplify
7x - 8 + 6x = 122
13x - 8 = 122
Inverse operations
13x - 8 = 122
+8 +8
13x = 130
/13 /13
x = 10
3. Find (m<TRS)
Now that one has the value of (x), one can substitute the value into the given expression for the (m<TRS), and solve to find the value.
m<TRS = 6x
x = 10
m<TRS = 6(10)
m<TRS = 60

A pebble falls off of a cliff at a height of
784 ft. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the pebble
to hit the ground?
Answer:
7 seconds
Step-by-step explanation:
You would get 49 from doing -784 divided by -16 then you do the square root of 49 which is 7
ANSWER= 7 seconds
The time taken by the pebble to hit the ground will be = 7 seconds
What is an Algebraic Equation?Expression we get when operations such as addition , subtraction , multiplication , division , are operated upon on variable and constants.
Equation of height as a function of time = h(t) = - 16 (t^2)
cliff is at a height of = 784 feet
comparing both the above equation , we get
-16 (t^2) = 784
t^2 = 49
t = 7 seconds
The time taken by the pebble to hit the ground will be = 7 seconds

What are the solutions of the equation
-12x+26=-(1/5)-x+2+3
Answer:
Step-by-step explanation:
Expand -(1/5)-x+2+3
-(1/5)-x+2+3
Remove the parenthesis;
=1/5-x+2+3
Add the numbers; 2+3=5
=-x+5-1/5
Convert element to fraction;
=5*5-1/5
Since the denominators are equal combine the fractions;
5*5/5-1/5
5*5-1=24
Multiply the numbers;5*5=25
=25-1
Subtract the numbers:25-1=24
=24
=-x+24/5
-12x+26=-x+24/5
Subtract 26 from both sides;
-12x+26-26=-x+24/5-26
Simplify;
-12x+26-26
Add similar elements; 26-26=0
=-12x
Simplify;-x+24/5-26
Convert element to fraction;
- 26/*5/5+24/5
Since the denominators are equal , combine the fractions;
-26*5+24
Multiply the numbers; 25*5=130
=-130+24
Add/subtract the number;-130+24=-106
=-106
=-106/5
Apply the fraction rule;
=-x-106/5
-12x=-x-106/5
Add x to both sides;
-12x+x=-x-106/5+x
Simplify;
-11x+=-106/5
Divide both sides by -11
-11x/-11=-106/5/-11
Simplify ;-11x/-11
Divide ;11/11
=1
=x
simplify;-106/5/-11
Apply fraction rule; 106/5/11
106/5*11
Multiply the numbers;5*11=55
=106/55
x=106/55
