A theater has 28 rows of 38 seats downstairs and 24 rows of 26 seats upstairs. How many seats does he theater have?
multiply rows by seats for each section then add them
28*38 = 1064
24*26 = 624
1064 + 624 =1688 total seats

The sun produces 3.8x10^27 joules of energy per second. How much energy is produced in a year? (Note: a year is approximately 31,000,000 seconds.) Put it in scientific form.
The total amount of energy produced by the sun in a year will be 11.78 × 10³⁴ joules.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The total amount of energy produced by the sun in a year can be calculated by multiplying the sun's energy production per second by the number of seconds in a year.
3.8 × 10²⁷ joules/second × 31,000,000 seconds/year
To express this in scientific notation, we can rewrite the number using powers of 10.
3.8 × 10²⁷ × 3.1 × 10⁷
11.78 × 10³⁴ joules
In this expression, the coefficient (11.78 ) is the number of units of energy produced, and the exponent (34) tells us the magnitude of the number. The exponent is based on the base of 10, so the number is 10 to the power of 34 or 1 followed by 34 zeros. This is a very large number and helps to give us a sense of the scale of energy production by the sun.

Which would most likely be graphed using a continuous graph? Check all that apply.
A. total cost, c, of buying b cans of beans
B. total cost, c, of buying g pounds of broccoli
C. speed of a car, s, as it accelerates over time, t
D. number of stamps, s, needed to mail p postcards
E. total distance, d, that has been driven over time, t
F. decrease in outside temperature, F, one evening over time, t
The example that would most likely be graphed using a continuous graph is B, C, E, and F.
What is Discrete and Continuous?Discrete refers to something that cannot be divided into fractions or decimals. People are an example; you cannot have half a person. We commonly say that distinct items can be numbered.
Continuous is anything that can and must be divided into fractions and decimals. We can measure continuous circumstances, which are called to be measured. Height is an illustration of this.
Now in the given list of examples, the data that is continuous will have a continuous graph. Therefore, the data can be sorted as,
A. total cost, c, of buying b cans of beans
The given example is discrete because you can not buy a half can.
B. Total cost, c, of buying g pounds of broccoli
The given data is continuous because pounds of broccoli can be in decimal form.
C. Speed of a car, s, as it accelerates over time, t
The given data is continuous because the time period can be in decimal form.
D.The number of stamps, s, needed to mail p postcards.
The given example is discrete because you can mail a half postcard.
E. total distance, d, that has been driven over time, t.
The given data is continuous because the time period can be in decimal form.
F. decrease in outside temperature, F, one evening over time, t.
The given data is continuous because the temperature can be in decimal form.
Hence, the example that would most likely be graphed using a continuous graph is B, C, E, and F.

A sweater is marked down $25 to $19 what is the percent of change
To solve the problem we must know about Percentage.
PercentageA percentage is a way to describe a part of a whole. such as the fraction [tex]\bold{\dfrac{1}{4}}[/tex] can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given to us
A sweater is marked down $25 to $19AssumptionLet the x% be the remaining amount.
Remaining Amountx% of $25 = $19
[tex]\dfrac{x}{100} \times \$25 = \$19\\\\\dfrac{x}{100} \times 25 = 19\\\\\dfrac{x}{4} = 19\\\\x = 19\times 4\\x = 76[/tex]
Thus, $19 is 76% of $25.
Percent of changethe percent of change = Orignal percentage - final percentage
= 100% - 76%
= 24%
Hence, the percentage change is 24%.

Which function represents the graph of y=10(4)x ?
f
g
h
j
Hence the the function that represents the graph of the given function is:
g
step-by-step-explanation:We are given graphs of four function.
f,g,h and j and we are asked to find which of the following given four graphs represents the graph of the function:
[tex]y=10\times 4^x[/tex]
Clearly when x=0 we see that the function gives the value.
[tex]y=10\times 4^0\\\\y=10\times 1\\\\y=10[/tex]
Hence when x=0 the graph of the function must pass through 10. i.e. the graph of the function passes through the point (0,10).
Hence the the function that represents the graph of the given function is:

Find a counterexample. If two lines are parallel, then they do not intersect. A. If two lines do not intersect, they could be skew. B. If two lines are parallel, they may intersect twice. C. If two lines are parallel, they intersect once. D. The statement is true. There is no counterexample.
Answer:
The answer would be D.
Step-by-step explanation:
The statement is true. There is no counterexample. Parallel lines never intersect because they are parallel to each other. So, it is impossible for parallel lines to intersect. Hope that answers your question.
A counterexample is an example that is against or opposite the theory. They disapprove of the generalization. In math's counterexample is used to slightly abuse and refers to the example which shows the need to fully hypothesize a theorem.
Such as all prime numbers are odd numbers as number 2 is a prime number but is an even number hence contradictory. As parallel lines are always at the same distance apart and never intersect.Hence the correct option is B. If two lines are parallel, they may intersect twice.
