What is the area, in square feet, of the trapezoid below?
Answer:
68.75
Step-by-step explanation:
Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.
13.6 + 5.9= 19.5
19.5 + 8 = 27.5
27.5 x 5 = 137.5
137.5 x 1/2 = 68.75
What integer describes 75 feet above sea level?
Answer:
75
Step-by-step explanation:
Sea level is considered 0. To find 75 feet above sea level, we add 75 to 0. This gets us 75. Since 75 is an integer, it checks out.
The required integer would be 75 which describes 75 feet above sea level.
What are Integers?Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer. Fractional numbers are not included in integers. Integers are represented by the symbol Z.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Let the sea level would be considered zero.
To determine 75 feet above sea level,
We have to add 75 to 0.
⇒ 75 + 0
⇒ 75
This obtains us 75.
Since 75 is an integer.
Therefore, the required integer would be 75 which describes 75 feet above sea level.

work!
Equation #1: 3x + 6 = x - 24
Equation #2: 10 – 2m = 16
Answer:
x = -15
m = -3
Step-by-step explanation:
3x + 6 = x - 24
subtract the x from both sides to make the unknown variable on only one side of the equation
2x + 6 = -24
subtract the 6 from both sides to focus on the x
2x = -30
now divide both sides by 2 to get the x by itself
x = -15
that's your answer
10 - 2m = 16
subtract the 10 from both sides to focus on the m
-2m = 6
now divide both sides by -2 to get the m by itself
m = -3
that's your answer
Sam walks from home to his school which is 0.75 miles away in 12 minutes. How fast was he walking?
Answer:
v = 3.75 mph
Step-by-step explanation:
Constant speed motion
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:
[tex]\displaystyle v=\frac{0.75\ mi}{0.2 \ h}[/tex]
v = 3.75 mph

Lupe is the manager of the football team, and she has to plan a team dinner for Saturday night. She knows that one large pizza can feed 3 players and one sandwich tray can feed 4 players. Lupe needs to order enough food for the 72 players on the team. (a) Write a linear equation to represent the number of pizzas (x) and the number of sandwich trays (y) she could purchase to feed the football players.
Answer:
3x + 4y = 72
Step-by-step exlanation:
Number of pizzas = x
Number of sandwich trays = y
one large pizza can feed 3 players
one sandwich tray can feed 4 players
Total players = 72
The linear equation is
3x + 4y = 72

Which number line represents the solution to 5x ≥ 30?
Answer:
Its B
Step-by-step explanation:
since the symbol has a line underneath its shaded so A & B are left.
the symbol shows > so the point is where the line goes, for this question it goes to the right.
The required number line represents the solution to 5x ≥ 30 is shown in option B.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.
Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.
Therefore, the correct answer is the number line shown in option B.

In a state with a population of 2,000,000 the average citizen
spends $6,000 on housing each year. What is the total spent on
housing for the state? Express answer in scientific notation.
Answer:
1.2×10¹⁰
Step-by-step explanation:
Given that,
The population of the state = 2,000,000
Average Citizen spends on housing = 6000
We need to find the total spent on housing for the state.
Total spent on housing for state = Population of State × Average Citizen
Total spent = 2,000,000 × 6,000
= 1.2×10¹⁰
Hence, the total spent on housing for the state is 1.2×10¹⁰.

Answer:
The Circumference of the circle = C = 24π mm
Hence, option C is true.
Step-by-step explanation:
Given
Radius r = 12mm
To Determine
Circumference of circle C = ?
Using the formula to determine the Circumference of the circle
C = 2πr
substituting r = 12mm in the equation
C = 2π(12)
C = 24π mm
Therefore, the Circumference of the circle = C = 24π mm
Hence, option C is true.

soo elimination method just means we want to cancel out on of the variable by subtracting of add the entire equations to each other... there is another method but this one is pretty good to learn with.
system 1
2x + 2y = -2
3x - 2y = 12
since there is already an easy way to get rid of the y variable lets just add the two equations together, just add term by term
5x + 0y = 10
if you notice .. just by making an imaginary column.. of each term.. you can just do that single piece by it self.... 2x + 3x = 5x and 2y +(-2y) = 0 and -2 + 12 = 10 :)
so now I can rewrite our new equation
5x = 10 I can solve this one with my eyes closed :D (10/5 = 2 )
x =2 :P
now , since we know x .. just plug in the known value of x into the 1st equations...
2(2) +2y = -2
4 + 2y =-2
2y = -2-4
2y = -6
y = - 3 :) ( I had to keep my eyes open that time b/c there was a minus sign floating about and those are too easy to mess up on .. when you do.. don't worry everyone does )
so we know
x = 2 and y = -3 :)
I'll go a little faster on 2.. and I see 3 is good for you to practice on.. just ask later if you have questions on that one.
system 2
4x - 2y = -1
-4x + 4y = - 2
add them again to get rid of the x term
0x +2y = -3
y = - 3/2
plug in y
4x - 2(-3/2) = -1
4x +3 = -1
4x = -1 - 3
4x = -4
x = -1
they are being nice and making them easy to start out.. you try system 3

Divide. Write the quotient in lowest terms.
5 divide 3 1/3
Answer:
3/2 or 1 1/2
Step-by-step explanation:
5÷3 1/3
5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide
5/1 × 3/10 because you have to multiply the first number by the reciprocal
5 and 10 cancel out so you would have 2 at the bottom

Sara is making 3 batches of chocolate chip
cookies and 3 batches of oatmeal cookies.
Each batch of chocolate chip cookies uses
2 cups of flour. She will use 122 cups of
flour for all six batches. Determine how
many cups of flour are needed for each
batch of oatmeal cookies.
3 batches of chocolate chip with 2 cups per batch is 6 cups total for the chocolate chip cookies.
Subtract the total needed for the chocolate chip from the total flour used, then divide the remaining amount by number of batches of oatmeal
Cookies.
The problem show 122 total cups, but I don’t think that is right... what is the actual total cups used?

At the beginning of an environmental study, a forest covered an area of 1500 km . Since then, this area has decreased by 2.4% each year. Lett be the number of years since the start of the study. Let y be the area that the forest covers in km². Write an exponential function showing the relationship between y and t.
Answer:
[tex]y = 1500(0.024)^t[/tex]
Step-by-step explanation:
Given
[tex]a = 1500km[/tex] -- initial area
[tex]b = 2.4\%[/tex] -- rate
[tex]t = time[/tex] --- (years)
Required
Represent as an exponential function
An exponential function has the form:
[tex]y = ab^t[/tex]
Where
[tex]a = initial\ value[/tex]
[tex]b = rate[/tex] and [tex]b \ne 1[/tex]
[tex]t= time[/tex]
Substitute values for a and b, we have:
[tex]y = 1500 * (2.4\%)^t[/tex]
Convert percentage to decimal
[tex]y = 1500 * (0.024)^t[/tex]
[tex]y = 1500(0.024)^t[/tex]
Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]
