Answer:
about 23.14 m.
Step-by-step explanation:
1/2(pi)(d). d=9.
so,
1/2(pi)(9)=4.5pim
then
4.5(pi)+9 is about 23.14m

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

update for the first one
Answer:
y = x + 2.5
Step-by-step explanation:
slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points
slope = (2.5-1.5)/(0+1) = 1
equation = y-y1 = m(x-x1)
y - 2.5 = x
y = x + 2.5

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

Here is an expression 3.2 evaluate the expression when t is 4 middle school math
Answer: Answer: C. 3.2 × 10^4
Step-by-step explanation: for this case the multiplication of the values with exponent are summed, as the exponent are the 6 and -3
6 - 3 = 3
this will be the exponent of the common value which is the 10.
after you only need to multiply 8 and 4 by separate the
8 * 4 = 32.
then we only need to place the values one by one
32 × 10^3
3 is the result of the sum of the exponent.
10 is the common value.
32 is the result of the product.
if we add another zero to the multiplication we get 3.2 and exponent finish with one more zero, then we get this result
3.2 × 10^4
because of that the C is the correct answer, keep in mind that the other answers do not apply correctly the rule of the exponent, because the rest of answer give us wrong answer with final result of the exponent.

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

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.
