Answer:
4
Step-by-step explanation:
We have an a-value and a c-value, which is -33/4 and 4, respectivley. Because c is the same as the y-intercept, we can tell the -intercept just from looking at the problem.

City Average Amount of Rainfall Abilene, TX 23.87 inches (in) Brownsville, TX 27.41 in Corpus Christi, TX 23.87 in Houston, TX 27.38 in Wichita Falls, TX 25.44 in If a meteorologist wanted to provide one number that explains how much the rainfall might differ amongst the given cities, which measure should the meteorologist provide and why? Group of answer choices
Mean; this will determine the average amount of rainfall all of the cities received.
Median; this will provide one measurement that provides the middle number of the measurements.
Mode; this will provide one measurement that occurred most frequently.
Range; this will determine the difference between the city with the least rainfall and the city with the greatest rainfall.
A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Answer:
192
Step-by-step explanation:
The area of the cereal box = 8 x 3 x 10 = 240
Therefore, if 100% of the box is filled with
cereal, the amount of cereal in the box
will be 240.
now, 80% is x
80/100 = x/240
cross multiplying,
100x = 80×240
100x = 19 200
dividing both sides by 100
x = 192
Answer:
192
Step-by-step explanation:
Each figure below is made up of congruent
trapezoids. Find the area of the figure.
Answer:
the area of trapizoid is 54 and all togather will be 108
Answer:
108 cm^2
Step-by-step explanation:
The formula for calculating the area of a trapezoid is (a+b)*h/2, a and b being the bases and h being the height.
Since the height of the figure is 12 cm, the height of each trapezoid is 12/2 = 6 cm because the trapezoids are congruent.
With this information we can calculate each trapezoid's area: (base 1 + base 2)*height / 2 = (6+12)*6/2 = 18*3 = 54 cm^2.
We know the area of one trapezoid is 54 cm^2, so two trapezoids would have an area of 108 cm^2 (the figure is composed of two trapezoids).

What comes next in this pattern? (add 4/6)
1/6, 5/6, 1 3/6, ...
A.1 5/6
B.2 2/6
C.2 4/6
D.2 1/6
Answer:
D. 2 1/6
Step-by-step explanation:
To visualize the problem easier, start by converting all the fractions to improper fractions, this will allow you to just add the denominators and simplify the question:
1/6, 5/6, 1 3/6 —> 1/6, 5/6, 9/6
Now that the sequence is rewritten, you can simply add 4 to the numerator, which equals 13/6.
Rewrite this again by finding how many times 6 goes into 13, and use the remainder as the numerator of the new fraction, which will end up as 2 1/6.

A. The more he chooses to pay off each month, the higher total interest he will pay.
B. The quicker he pays off the credit card, the more interest he will pay.
C. The more he chooses to pay off each month, the less total interest he will pay.
D. The amount he chooses to pay each month will not affect the total interest he pays.
letter B is the answer
Step-by-step explanation:
she needs some credit
The correct conclusion from the table shows C. The more he chooses to pay off each month, the less total interest he will pay.
How is interest determined?The interest amount is calculated based on the outstanding balance.
When a cardholder makes more monthly payments, the interest amount reduces because of the reduction in the outstanding balance.

Luz drives at an average speed of 60 miles per hour.
She has driven for 2 hours and has traveled a distance of 120 miles.
This situation can be represented with a linear equation written in point-slope form, where x represents the number of hours and y represents the number of miles.
Use this information to complete each statement about the linear equation
Answer:
1) This linear equation has a slope of 60
2) (2, 120)
3) [tex]y - 120 = m(x - 2)[/tex]
Step-by-step explanation:
1) This situation represents a linear time-distance relationship where:
x represents the time
y represents the distance travelled
Slope is equal to △y/△x
Substituted form: [tex]\frac{120}{2}[/tex]
Slope is equal to 60.
2) Using the statement:
She has driven for 2 hours and has traveled a distance of 120 miles, we know that knowing that x represents the time and y represents the distance:
A possible coordinate is (2, 120)
3) Using the point slope standard equation and our known values, we can substitute the values. The correct answer is y - 120 = m(x - 2)
