The difference of two numbers is 5. The sum of three times the larger number and twice the smaller number is 30. What is the smaller number?
Answer: 3
Step-by-step explanation:
Let the smaller number be y.
Since the difference of two numbers is 5,then the larger number will be: y+5
The sum of three times the larger number and twice the smaller number is 30. This can be written as:
3(y+5) + 2y = 30
3y + 15 + 2y = 30
5y + 15 = 30
5y = 30 - 15
5y = 15
y = 15/5
y = 3
The smaller number is 3

Mara is building a set of shelves supported by a diagonal brace, as shown in the diagram. Answer the questions to decide whether all three shelves are parallel. 1. If ∠2 measures 120°, what is the measure of ∠1? Explain how you found the measure of ∠1. (The image) Write your answer in the space below. 2. Think of the top and middle shelves as two lines cut by a transversal. What type of angles are ∠1 and ∠5? Write your answer in the space below. 3. Use the relationship between ∠1 and ∠5 to decide whether the top and middle shelves are parallel. Write your answer in the space below. 4. Is the bottom shelf parallel to the top shelf? Explain. Write your answer in the space below. 5. Is the bottom shelf parallel to the middle shelf? Explain. Write your answer in the space below.
Answer:
Step-by-step explanation:
1). Since, m∠1 + m∠2 = 180° [Supplementary angles]
If m∠2 = 120°
m∠1 + 120° = 180°
m∠1 = 180° - 120°
m∠1 = 60°
2). If a transversal intersects two parallel lines on the top and middle,
∠1 and ∠5 will be corresponding angles.
3). Since, m∠1 = m∠5 = 60° (Corresponding angles)
Therefore, both the lines on top and middle will be parallel.
4). Since, m∠9 + m∠11 = 180° [Supplementary angles]
If m∠11 = 120°
m∠9 + 120° = 180°
m∠9 = 60°
Since, m∠1 = m∠9 = 60° [Corresponding angles]
Therefore, both the lines on the top and bottom shelves will be parallel.
5). Since, m∠5 = m∠9 = 60° [Corresponding angles]
Therefore, middle and bottom shelves will be parallel.

A circular pool has a diameter of 16 meters. What is the area and circumference of the pool? Circumference: 50.24 meters; Area: 200.96 square meters Circumference: 50.24 meters; Area: 803.84 square meters Circumference: 100.48 meters; Area: 200.96 square meters Circumference: 100.48 meters; Area: 803.84 square meters
Step-by-step explanation:
Circumference = πD
= 16π
= 50.265482457437
Area =
π( D )2
2
= 64π
= 201.06192982975
The Circumference of the circle is 50.24 meters and The area of the circle is 200.96 meters.
What is the Circumference of a Circle?
A circle's perimeter is known as its circumference. It is the circumference of the circle as a whole. A circle's circumference is calculated by multiplying its diameter by the constant. This measurement of a circle's diameter is necessary for someone crossing a circular park or for enclosing a circle. The units for the circumference, which is a linear variable, are the same as those for length. A circle is a closed, rounded shape whose border points are all equally spaced out from the center. The diameter and area of a circle are two crucial measurements of a circle.
What is the Area of a Circle?
The space a circle takes up on a two-dimensional plane is known as the area of the circle. Alternately, the area of the circle is the area included inside the circumference or perimeter of the circle. A = r×r×pi, where r is the circle's radius, is the formula for calculating a circle's surface area.
So, here in the question, It is given that:
The diameter of the circle (d) = 16 meters
and we know that the Radius of a circle is half of the diameter.
That is,
[tex]d = 2r[/tex]
⇒[tex]r = \frac{16}{2}[/tex]
⇒[tex]r = 8 m[/tex]
So,
Circumference of the circle = 2πr
⇒Circumference = 2×3.14×8
⇒Circumference = 50.24 meters.
And, Area of the circle = π×r×r
⇒Area = 3.14×8×8
⇒Area = 200.96
Hence,
Circumference of the circle = 50.24 meters;
Area of the circle = 200.96 meters;

American eat an average of 100 acres of pizza per year this is equivalent to 4,356,000 square feet of pizza per year how is area express using scientific notation
Answer:
4.356 × 10⁶ square feet or 4.356 × 10⁶ ft² of pizza per year
Step-by-step explanation:
Scientific notation is a means, method or way that is used in mathematics to write very large or small real numbers in a very short form or compressed form.
Scientific notation uses exponents or 10 raised to the power of a particular number to write huge or small real number in a decimal form.
In the question, we are asked to express the area in square feet as a scientific notation.
The area = 4,356,000 square feet of pizza per year
4,356,000 square feet of pizza per year in scientific notation =

What are the domain and range of the function represented by the table?
Answer:
C
Step-by-step explanation:
Apex
The domain of the function is (-8, -6, -4, -2,0) and the range is 2. The correct option is C.
What are a range and domain?The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x).
A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
The given data is as below:-
x ( -8, -6, -4, -2, 0 )
y ( 2 , 2 , 2 , 2 , 2 )
For all the values of x, the output is 2. The domain of the function is (-8, -6, -4, -2,0) and the range is 2.
Therefore, the domain of the function is (-8, -6, -4, -2,0) and the range is 2. The correct option is C.

What percent of 56 is 44.8
Answer:
80%
Step-by-step explanation:
1. We assume, that the number 56 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 56, so we can write it down as 100%=56.
4. We know, that x% equals 44.8 of the output value, so we can write it down as x%=44.8.
5. Now we have two simple equations:
1) 100%=56
2) x%=44.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=56/44.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 44.8 is what percent of 56
100%/x%=56/44.8
(100/x)*x=(56/44.8)*x - we multiply both sides of the equation by x
100=1.25*x - we divide both sides of the equation by (1.25) to get x
100/1.25=x
80=x

Teresa runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?
Answer:
She would run about 5.8 miles in 64 min.
Step-by-step explanation:
Let m= miles per minute
7=80m divide 80 on both sides.
0.0875=m Round
0.09 miles per minute
0.09 x 64= 5.76 round or leave it like that
5.8
Answer:
[tex]\boxed {\tt 5.6 \ miles}[/tex]
Step-by-step explanation:
Let's set up a proportion using the following setup:
[tex]\frac{miles}{minutes}= \frac{miles}{minutes}[/tex]
We know Teresa can run 7 miles in 80 minutes.
[tex]\frac{7 \ miles}{80 \ minutes}=\frac{miles}{minutes}[/tex]
We don't know how many miles she can run in 64 minutes. Therefore, she can run x miles in 64 minutes.
[tex]\frac{7 \ miles}{80 \ minutes}=\frac{x \ miles}{64 \ minutes}[/tex]
[tex]\frac{7}{80} =\frac{x}{64}[/tex]
We want to solve for x ( miles in 64 minutes). We must isolate x on one side of the proportion. x is being divided by 64 and the inverse of division is multiplication. Multiply both sides of the equation by 64.
[tex]64*\frac{7}{80} =\frac{x}{64}*64[/tex]
[tex]64*\frac{7}{80} =x[/tex]
[tex]64*0.0875=x[/tex]
[tex]5.6=x[/tex]
x= 5.6 miles
Teresa can run 5.6 miles in 64 minutes.
