Admission to a baseball game is $4.50 for general admission and $6.50$6.50 for reserved seats. The receipts were $5008.50 for 945
paid admissions. How many of each ticket were sold? (Round to nearest integer if necessary.)

Answers

Answer 1
Answer:

Answer:

general admission tickets = 567

reserved tickets = 378

Step-by-step explanation:

Let number of general admission tickets be "g"

and number of reserved seats be "r"

Total 945 tickets, that means:

g + r = 945

Also, total value of all tickets is 5008.5, so we can write:

4.5g + 6.5r = 5008.5

We can write 1st equation as:

g = 945 - r

Now we plug it into 2nd equation and solve for r first:

4.5g + 6.5r = 5008.5\n4.5(945-r) + 6.5r = 5008.5\n4252.5-4.5r+6.5r=5008.5\n2r=756\nr=378

Now, g is equal to:

g = 945 - r

g = 945 - 378

g= 567

So, reserved tickets sold were 378

and

general admission tickets sold were 567

What percent of the boxes have x's in them

Answers

There are 32 total boxes. Only 14 of the boxes in the grid have an x inside of the box. We can find what percent of the boxes have an x in them by making a fraction. (14)/(32) represents the number of boxes that have an x in them out of all the boxes in the grid.

(14)/(32) can be reduced to (7)/(16) by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 32 which is 2.

7 ÷ 16 = 0.4375

0.4375 × 100 = 43.75%

Therefore, 43.75% of the boxes have an x inside of them.
It is a 4 by 8 grid.  So there are 32 squares total.
Now,  count how many x's are on the boxes.
I counted 14 x'ed boxes.
Divide 14 by 32
14/32=0.4375
Now convert to a percent.  Move the decimal two places to the left.
You get 43.75% as the answer.

Explain what are 2 fractions that are alike fractions

Answers

Are you asking what are like fractions? If so, like, or alike fractions are two fractions with the same denominator, (the bottom number of the fraction).
 For example, 1/10 and 7/10. If that was not what you were asking, please let me know and I'll try my best. Hope this helped you!

According to the Fundamental Theorem of Algebra, the graph of f(x) = x2 - 4x + 3, has roots. From the graph we can see that it has zeros.

Answers

Answer:

The graph f(x)=x^2-4x+3  has two zeros namely 3 and 1.

Step-by-step explanation:

Consider the given equation of graph f(x)=x^2-4x+3

According to the Fundamental Theorem of Algebra

For a given polynomial of degree n can have a maximum of n roots.

Thus, for the given equation f(x)=x^2-4x+3  the degree of polynomial is 2 , thus the function can have maximum of 2 roots.

We know at roots the value of function is 0 that is f(x) = 0,

Substitute f(x) = 0 , we get, f(x)=x^2-4x+3=0

This is a quadratic equation, x^2-4x+3=0

We first solve it manually and then check by plotting graph.

Quadratic equation can be solved using middle term splitting method,

here, -4x can be written as -x-3x,

x^2-4x+3=0 \Rightarrow x^2-x-3x+3=0

\Rightarrow x(x-1)-3(x-1)=0

\Rightarrow (x-3)(x-1)=0

Using zero product property, a\cdot b=0 \Rightarrow a=0\ or \ b=0

\Rightarrow (x-3)=0 or \Rightarrow (x-1)=0

\Rightarrow x=3 or \Rightarrow x=1

Thus, the two zero of f(x) are 3 and 1.

We can also see on graph attached below that the graph f(x)=x^2-4x+3  has two zeros  namely 3 and 1.

2 roots

Answer:

The average of -2.5, 5.2, 1.7, and -0.8 is 0.9

Step-by-step explanation:

You are taking the mean of all the values

So you would add -2.5, 5.2, 1.7, and -0.8 all together

This gives you 3.6

Then you would divide by the number of numbers per se,

Which would give you the answer: 0.9
Add them up then divide by 4 and you’ll get 0.9

How would you convert a mass in centigrams to a mass in milligrams?

Answers

Basically, add a zero, since that is one step down on the Metric Conversion Chart. (I'll add that at the bottom!)

So if I had 50cm of a Shrimp Ramen Noodle Packet, I'd have 500mg of the Shrimp Ramen Noodle Packet!

Metric Conversion Chart-
All you have to do is add a 0

so if I had 10 centigrams of sugar it would be 100 milligrams of sugar.
