Answer:
a^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
90^2 + 120^2 = c^2
8100 + 14400 = c^2
22500 = c^2.....take the sq rt of both sides...this gets rid of the ^2
sq rt 22500 = c
150 = c
so side a = 90 ft, side b = 120 ft, and side c = 150 ft
this is called the pythagorean theorem and it only works on right triangles

The following tables show some values from three different functions. which of these functions could be quadratic?
Answer:
C. III only
Step-by-step explanation:
a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.
so, let's look at the tables.
table I shows the powers of 2. y = 2^x
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
so, it is not saying anything in general.
table II shows an "identity" equation. y = x
0 = 0
1 = 1
2 = 2
3 = 3
this does not square anything.
table III shows then finally a square equation. y = x^2
0^2 = 0
1^2 = 1
2^2 ≈ 4
3^2 = 9

4. If f(x)=2x+3(x+4)+5 then f(6)=?
Answer:
f(6)=42
Step-by-step explanation:
We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.

Answer: 47
Step-by-step explanation:
That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.
if the sum of two number is 37 and the greater number exceeds the smaller by 5, find the numbers.
Answer:
21 and 16
Step-by-step explanation:
x= big number
x`-5 = small number
x + x-5 = 37
2x-5 =37
2x= 42
x = 21
21-5 = 16
21+16 = 37

What is the sum of the of what is the sum of the given arithmetic series?
5 + 8 + 11 + ... + 92
O 1554
O 1545
O 1455
O None of these
Answer:
3rd option : 1455
Step-by-step explanation:
here, a = 5, d = 3 , tn = 92, n = ?, Sn = ?
tn = [a + (n - 1) d]
92 = [ 5 + (n - 1)d
92 = 5 + 3n - 3
92 - 5 + 3 = 3n
90 = 3n
n = 90/3
n = 30
By sum of first n terms of an A. P formula,
Sn = n/ 2 [ 2a + (n - 1) d]
Sn = 30/2 [ 2 * 5 + (30 - 1) 3]
Sn = 15[ 10 + 29 ( 3) ]
Sn = 15[ 10 + 87 ]
Sn = 15( 97 )
Sn = 15 * 97
Sn = 1455
Therefore, option 3rd 1455 is correct.

Answer:
[tex]\frac{96}{91}[/tex] or 51.69
Step-by-step explanation:
[tex]\frac{-6}{13}[/tex] x reciprocal of [tex]\frac{-7}{16}[/tex]
Reciprocal of [tex]\frac{-7}{16}[/tex] is [tex]\frac{-16}{7}[/tex]
So, the equation would be:-
[tex]\frac{-6}{13}[/tex] x [tex]\frac{-16}{7}[/tex]
= [tex]\frac{96}{91}[/tex]
The product would be [tex]\frac{96}{91}[/tex].

Lydia buys peanut butter in bulk for $0.20 an ounce. How much does 18 ounces of the peanut butter cost?
Answer:
3.6 dollars
Step-by-step explanation:
Lets go over what we know:
Each ounce of penut butter cost 0.2$, or 1/5$
We need 18 ounces.
To solve this, lets multiply the cost per ounce by the amount of ounces:
0.2*18
Or
1/5*18
=
18/5
This can be simplfied into:
3 3/5
We know each 1/5 is 20 cents(0.2), so 3 cents would be 3*0.2 = 0.6:
3.6 dollars
So the answer is for 18 ounces, it cost 3.6 dollars.
Hope this helps!

What is the area, in square centimeters, of an equilateral triangle with a perimeter of 15 centimeters? Round the answer to the nearest tenth.
Answer:
A≈10.83cm²
Step-by-step explanation:
Unit Conversion:
P=15cm
Using the formulas
A=3
4a2
P=3a
Solving forA
A=3P2
36=3·152
36≈10.82532cm²
Answer:
10.8 cm^2 to nearest tenth.
Step-by-step explanation:
You can use Hero's formula to do this:
Area = √[s(s-a)(s-b)(s-c)] where s = semi-perimeter, a b and c are the lengths of the 3 sides,
Here s = 15/2 = 7.5 and a, b and c = 5.
area = √(7.5 * 2.5 * 2.5 * 2.5)
= √117.1875
= 10.8253.
Another method would be to use trigonometry
h = 5 sin 60 and 1/2 * base = 1/2 * 5 = 2.5
So area = 5 sin60 * 2.5 = 10.8253,
-7n = 84 round to the nearest hundredth

Step-by-step explanation:
Paul is comparing two high-speed Internet service providers (ISPs) for his business. The graph represents the cost of each ISP as a function of t, the duration in months of a service contract.
A coordinate grid showing Internet Service Provider Cost, with Service Contract in months along the horizontal axis, and Total Cost in dollars along the y-axis. Two lines are graphed. One line is labeled I S P A and passes through (0, 180) and (12, 300). The second line is labeled I S P B and passes through (0, 0) and (12, 300).
If C(t) = 180 + 10t represents ISP A and C(t) = 25t represents ISP B, how long would the service contracts need to be for the total costs to be the same?
6 months
8 months
10 months
12 months
Answer:
12 months
Step-by-step explanation:
Theres an awful amount of needless information to get through.
Only the last paragrph is needed.
C(t) = 180 + 10t
C(t) = 25t
Set the equations equal
25t = 180 + 10t
Subtract 10t from both sides
15t = 180
Divide both sides by 15
t = 12
Answer:
12 months

A. 37.5%
B. 26.7%
C. 7.1%
D. 14.1%
Answer:
C. 7.1
Step-by-step explanation:
Answer:
The probability that a dart thrown at random within the dartboard will hit the bull's eye is 14.1%
Step-by-step explanation:
[tex]The probability is found by dividing the area of the bull's eye by the total area of the dart board:\[\large P(bull's\ eye)=\frac{\pi\ 6^{2}}{\pi\ 16^{2}}=\frac{36}{256}=0.1406\]Therefore your answer of 14.1% is close.[/tex]

Wayne earned a total of $8 by selling 4 cups of lemonade. After selling a total of 5 cups of
lemonade, how much money will Wayne have made in all? Solve using unit rates.
Answer:
$10
Step-by-step explanation:
Unit rate
$8/4cup = $2/cup
Therefor
5 cups * $2/cup = $10
Answer:18$
Step-by-step explanation:first you wanna see the rate 8 dollars for 4 cups so 8/4 gives you 2.The rate is 2 dollars per cup.
So now we have to find how much 5 cups is worth.Since we know how much each lemonade cost we just have to plug it all in!So 5*2.Is 10 and we also made 8 bucks from the first 4 cups.
Now that we know that we sold 8$ the first time and 10$ the second we add them all up to give you “18$“total
