Joel cut the longest piece of fencing in order to make a right triangle. Find the perimeter of Joel's fence.
He needs 20 minutes to install all of the fence.
Since we have given that
Dimensions of triangle he has to use for fencing are
15 feet, 8 feet, and 20 feet.
1) For making it a right triangle it must satisfy the "Pythagorus theorem" which states that
H²= B²+P²
⇒ 20²= 15²+8²
⇒ 400 ≠ 225+64
⇒ 400≠ 289
No, it will not be able to make a right triangle.
2) Joel cut the longest piece of wood in order to make a right triangle.
So, from above we get that
√289= 17 FEET
So, Longest side must be 17 feet.
It is takes him 30 seconds to install each foot of fencing,
Total perimeter of fencing will be
17+15+8=40 feet
So, for 1 foot he needs = 30 seconds
For 40 feet , he will need
40×30=1200 seconds
1200/60
= 20 MINUTES
Hence, he needs 20 minutes to install all of the fence.

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
9/70
Step-by-step explanation:
Mathematically;
Average rate of change on an interval [a,b] is;
f(b) - f(a)/b-a
f(0) = -3/5
f(3) = -3/14
a = 0
b = 3
Making the substitution, we have
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70

Mr. Grouper has budgeted $2000 for a graduation party for his son. The cost to rent the venue is $150 and each guests receives a $3.50 gift. How many people can Mr. Grouper invite to his sons graduation party?
Answer:
Mr. Grouper can invite 528 people to his sons graduation party.
Step-by-step explanation:
x= number of people
3.50x +150 =2000
-150
3.50x = 1850
1850/ 3.50
528.571428571 = 528
Mr. Grouper can invite around a total of 528 people to attend for the graduation party of his son.
What is Equation?Equation is a statement including expressions on two sides related by an '=' sign. This may or may not include two or more variables and can be solved using various methods.
Total budget for the graduation party = $2000
Cost to rent the venue = $150
Cost of gift for each guest = $3.50
Let n be the number of guests invited for the party.
Then 3.50n will be the total cost for the guests.
Then we have the linear equation,
150 + 3.50 n = 2000
Solving this will get the number of guests, n.
3.50n = 2000 - 150
3.50n = 1850
n = 1850 / 3.50
n = 528.57 ≈ 528
Hence Mr. Grouper can invite almost 528 people to his son's graduation party.

Write the equation in slope intercept form y - 4=10(x-5)
Answer:
y = 10x - 46
Step-by-step explanation:
slope intercept form: y = mx + b
m is slope and b is y-intercept
given: y - 4 = 10(x-5)
1. distibute 10
y - 4 = 10x - 50
2. we need to get y by itself so bring -4 to other side
y = 10x - 50 + 4
y = 10x - 46
slope-intercept form is [tex]y=mx+b[/tex]
[tex]y=10(x-5)+4[/tex] ↣ We move -4 to another side and become positive number.
[tex]y=(10x-50)+4[/tex] ↣ Distribute 10 inside the brackets.
[tex]y=10x-50+4\\y=10x-46[/tex] ↣ Then we get the slope-intercept form.
Thus, the answer is [tex]y=10x-46[/tex]

Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below. What is the correct amount Vince will pay back altogether?
Answer:
the correct amount that Vince have to pay back altogether is $927
Step-by-step explanation:
The computation of the correct amount that Vince have to pay back altogether is as follows:
As we know that
Amount = Principal + Principal × rate of interest × time
= $900 + $900 × 0.015 × 2
= $900 + $27
= $927
Hence, the correct amount that Vince have to pay back altogether is $927

[tex]y-2=-\frac{1}{3}(x+6)\\y=-\frac{1}{3}(x+6)+2[/tex]
Simply move -2 to another side.
[tex]y=-\frac{x}{3}-2+2[/tex]
Distribute -1/3 in (x+6)
[tex]y=-\frac{x}{3}[/tex] ---> Answer
Answer:
x + 3y = 0
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y - 2 = - [tex]\frac{1}{3}[/tex] (x + 6) ← distribute
y - 2 = - [tex]\frac{1}{3}[/tex] x - 2 ( add 2 to both sides )
y = - [tex]\frac{1}{3}[/tex] x ( multiply through by 3 to clear the fraction )
3y = - x ( add x to both sides )
x + 3y = 0 ← in standard form
in a different plan for area codes, the first digit could be any number from 4 through 8, the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7 with this plan, how many different area codes are possible?
There are 160 possibilities for area codes
We are required to find all the combinations for different area codes
It is given to us that the conditions for the tree digit area code are:
first digit could be any number from 4 through 8,
the second digit was either 4 5 6 or 7, and the third digit could be any number except 2 or 7
Using the conditions above, the digits which can be first digit of code = 4 through 8 =4,5,6,7,8
the digits which can be second digit of code= 4,5,6,7
the digits which can be third digit of code = 0,1,3,4,5,6,8,9
number of possibilities for first digit= 5
number of possibilities for second digit=4
number of possibilities for third digit= 8
Therefore, total number of possibilities of code = number of possibilities of first digit x number of possibilities of second digit x number of possibilities of third digit = 5 x 4 x 8=160
Therefore, there are 160 possibilities for area codes

After being dilated by a scale factor 1.5?
Given:
The given figure is dilated by a scale factor 1.5.
To find:
The coordinates of B' and C'.
Solution:
If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is
[tex](x,y)\to (k(x-a)+a,k(x-b)+b)[/tex]
From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).
The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is
[tex](x,y)\to (1.5(x-3)+3,1.5(x-(-3))+(-3))[/tex]
[tex](x,y)\to (1.5(x-3)+3,1.5(x+3)+(-3))[/tex]
[tex](x,y)\to (1.5(x)-4.5+3,1.5(x)+4.5-3)[/tex]
[tex](x,y)\to (1.5x-1.5,1.5x+1.5)[/tex]
Using this rule, we get
[tex]B(-2,2)\to B'(1.5(-2)-1.5,1.5(2)+1.5)[/tex]
[tex]B(-2,2)\to B'(-3-1.5,3+1.5)[/tex]
[tex]B(-2,2)\to B'(-4.5,4.5)[/tex]
And
[tex]C(-3,-5)\to C'(1.5(-3)-1.5,1.5(-5)+1.5)[/tex]
[tex]C(-2,2)\to C'(-4.5-1.5,-7.5+1.5)[/tex]
[tex]C(-2,2)\to C'(-6,-6)[/tex]
Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).
