At a concert 6 out of the first 20 people who entered the
concert were wearing hats. Based on this information, if
there are 800 people at the concert, how many of these
people are expected to be wearing a hat?
Answer:
240 people
Step-by-step explanation:
6/20=x/800
800*6=20x
4800=20x
240=x
Therefore, you would expect 240 people to be wearing a hat

Graph each equation. Determine the solution of the system of equations. Use pencil and paper. Explain how to find the equation of a line that intersects the system of equations at the same point.
1) x=y
2) 4x= 3y - 3
9514 1404 393
Answer:
see attached
use the point-slope form
Step-by-step explanation:
Substitution works to find the solution.
4x = 3x -3
x = -3 = y
The solution is (x, y) = (-3, -3).
__
The first equation graphs as a line through the origin with a slope of 1.
The second equation graphs as a line through (0, 1) with a slope of 4/3, that is, a rise of 4 for each run of 3.
The two lines intersect at (x, y) = (-3, -3), so that point, together with the y-intercepts, can be used to draw the lines.
_____
A line that intersects point (-3, -3) can be written in point-slope form as ...
y +3 = m(x +3) . . . . . for some slope m.
If you were to choose m = -1, this becomes ...
y +3 = -(x +3)
y = -x -6 . . . . . . rearranged to slope-intercept form

Answer:
25 units
Step-by-step explanation:
The longest side is 12.
The two other sides of the triangle = (3 sqaured + 6 squared) (9+36) the square root of 45 is about 6.7.
6.7 x 2 = 13.4
13.4 + 12 = 25.4
25.4 rounded to the nearest unit is 25

On a recent math test a teacher asked for the measure of
Answer:
It equals 97°
Step-by-step explanation:
The mistake she made was she thought angle t was vertical to angle u and thus it has the same value. Vertical angles have to be across from each other and not on top of each other. So why does it equal 97? If we look at angle y it has the same value and the angles are exactly the same. Look below for the other explanation since it can't really be said by words.

The graph shows the distance, in miles, that Anders traveled over a period of nine hours.
Use the graph to determine the constant of proportionality between the number of miles traveled and the number of hours traveled.
A. 60
B. 65
C. 130
D. 585
Answer: B. 65
Step-by-step explanation:
Choose any point on the number line with natural numbers for both coordinates. For this case, let's use (4, 260).
To find the constant of proportionality, divide the Y coordinate by the X coordinate. 260 ÷ 4 = 65. While optional, it is reccomended to use two points to confirm your answer. Let's do that with (2, 130). Since 130 ÷ 2 = 65, this confirms that the constant of proportionality is 65.
These two screenshots both have the information you can use for the answer. The first screenshot is the chart and the second is the question.
Answer:
10.5 miles after 7 hours
Step-by-step explanation:
Step-by-step explanation:
Let h be the number of hours spent
Let d be the distance travelled
given d = 1.5 when h = 1, and d = 3 when h = 2,
d = 1.5h
given h = 7,
[tex]d = 1.5 \times 7 \\ = 10.5miles[/tex]

Use the distributive property to write an expression that is equivalent to 8( a + 4 ). 8(a+4) = blank a + blank
Answer:
8a+32
8(a+4)= 8a+32
Hope it helps :D
Step-by-step explanation:
Answer:
[tex] \sf \: 8a + 32 [/tex]
Step-by-step explanation:
Now we have to,
→ Find the equivalent expression.
The property we use,
→ Distributive property.
The expression is,
→ 8(a + 4)
Let's simplify the expression,
→ 8(a + 4)
→ 8(a) + 8(4)
→ (8 × a) + (8 × 4)
→ 8a + 32
Hence, the answer is 8a + 32.

How much did the two heaviest tomatoes weigh all together?
Answer:
1 and 6/8
Step-by-step explanation:
1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.
