Answer:
If you need to find the hypotenuse, then square the two sides and add them together then square root that answer to get the hypotenuse. If you need to find a side then take the hypotenuse and other side and square them then subtract the side by the hypotenuse and then square root that answer.
Step-by-step explanation:
legs; a b hypotenuse c
a^2 + b^2 = c^2 then square root this answer
c^2 - b^2 = a^2 then square root this answer
c^2 - a^2 = b^2 then square root this answer

Anthony borrowed $15 from his mom to pay for food at the school dance. He bought one snow cone for $3, and then used the rest of his money to buy as many chocolate bars as he could. If chocolate bars cost $0.75, then how many chocolate bars could Anthony buy? Part A Select the correct equation to determine the number of chocolate bars Anthony can buy Part B How many chocolate bars can Anthony buy?
0.75x+3=15
16 chocolate bars
Answer:
a= 15 = 3+ .75c
b= 16 chocolate bars
Step-by-step explanation:
15 = 3 + .75c
c= chocolate bars
to solve for the number of chocolate bars:
subtract three for the snowcone he bought= 12=.75c
then just divide by .75 = 16 = c=16

A Wonsan has 30 coins in her pocket, all of which are dimes and quarters . If the total value of the coins is $4.50 ,how many dimes and how many quarters does she have ?
Answer:
The number of
Dimes = d = 20 dimes
Quarters = q = 10 quarters
Step-by-step explanation:
Let us represent
The number of :
Dimes = d
Quarters = q
Note that:
A dime is worth 10 cents = 0.10d
A quarter is worth 25 cents = 0.25q
A Wonsan has 30 coins in her pocket, all of which are dimes and quarters .
d + q = 30...... Equation 1
d = 30 - q
If the total value of the coins is $4.50
0.10d + 0.25 q = 4.50.....Equation 2
We substitute 30 - q for d in Equation 2
0.10(30 - q) + 0.25q = 4.50
3 - 0.10q + 0.25q = 4.50
- 0.10q + 0.25q = 4.50 - 3
0.15q = 1.5
q = 1.5/0.15
q = 10 quarters
Solving for d
d = 30 - q
d = 30 - 10
d = 20 dimes
Therefore:
The number of
Dimes = d = 20 dimes
Quarters = q = 10 quarters

Step-by-step explanation:
if thrice my age 6 years ago be subtracted from twice my present age the result is present age then my present age is what
Answer:
9 years
Step-by-step explanation:
Let the present age = x
Age 6 years ago = x - 6
Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18
Twice my present age = 2 *x = 2x
Thrice my age 6 years ago be subtracted from
twice my present age = 2x - (3x - 18)
2x - (3x - 18) = x
2x - 3x + 18 = x
-x + 18 = x {Add x to both sides}
18 = x + x
18 = 2x {Divide both sides by 2}
18/2 = x
x = 9 years

Answer:
The terms combine into 9x + 17
Step-by-step explanation:
What you need to realise here is that the brackets don't serve any real purpose, as there's no operation being done on their contents as a whole. With that in mind we can simply drop the brackets and group like terms:
(4x + 8) + (5x + 9)
= 4x + 8 + 5x + 9
= 4x + 5x + 8 + 9
= 9x + 17
So the terms combine into 9x + 17
Find the sum of the first 90 terms of the sequence –4, –1, 2, 5, 8, ...
a.
11654
c.
11656
b.
11657
d.
11655
Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
S90 = 11,655

a football coach is trying to decide: when a team is ahead late in the game, which strategy is better?
• play the "regular" defense.
• play a "prevent" defense that guards against long gains but makes short gains easier
the coach reviews the outcomes of 100 games
compare the probability of winning when playing regular defense with the probability of winning when playing prevent defense. draw a conclusion
based on your results.
From analysis, it is seen that the probability of winning when playing regular defense is higher than the probability of winning with *prevent* defence.
How to find the probability of Winning?We will assume that a total of 100 games were reviewed.
50 games used regular defense method.
The remaining 50 games used the prevent defense method.
Out of the 50 regular defense games, 38 were win while 12 games were lose.
Out of 50 prevent defense game, 29 were win, while 21 games were lose.
Thus, the Probability of winning by regular defense is:
P(win | regular) = 38/50
P(win | regular) = 0.76
Probability of winning by playing prevent defense is:
P(win | prevent) = 29/50 = 0.58
From the above analysis we observe that the probability of winning by using the regular defense method is greater than the probability of winning by prevent defense method.
That is 0.76 > 0.58.

Aditya is celebrating his birthday. He invited his friends. He bought a packet of toffees/candies which contains 120 candies. He arranges the candies such that in the first row there are 3 candies, in second there are 5 candies, in third there are 7 candies and so on.
(a) Find the total number of rows of candies.(i) 12 (ii) 10 (iii) 14 (iv) 8
(b) How many candies are placed in last row? (i) 22 (ii) 21 (iii) 24 (iv) 18
(c) Find the difference in number of candies placed in 7th and 3rd row. (i) 8 (ii) 10 (iii) 12 (iv) 14
(d) If Aditya decides to make 15 rows, then how many total candies will be placed by him with the same arrangement? (i) 200 (ii) 150 (iii) 255 (iv) 210
(e) Find the number of candies in 12th row.(i) 21 (ii) 30 (iii) 25 (iv) 19
Answer:
(a) 10, (b) 21, (c) 8, (d) 255, (e) 25Step-by-step explanation:
(a)Total number of candies = 120
The number of candies in the rows form AP sequence:
3, 5, 7, ...The first term is a=3 and common difference is d=2
Sum of n terms:
S = 1/2n(2a + (n - 1)d)Substitute values and solve for n:
120 = 1/2n(2*3 + 2(n - 1)) 120 = 3n + n² - nn² + 2n = 120n²+ 2n + 1 = 121(n + 1)² = 121n + 1 = 11n = 10Correct choice is (ii) 10
(b) Formula for nth term:
a(n) = a + (n - 1)da(10) = 3 + 9*2 = 3 + 18 = 21 candiesCorrect choice is (ii) 21
(c) Use same formula:
a(7) - a(3) = a + 6d - a - 2d = 4d4d = 4*2 = 8Correct choice is (i) 8
(d) Sum of candies in 15 rows
S(15) = 1/2(15)(2*3 + (15 - 1)*2) = 1/2(15)(6 + 28) = 255Correct choice is (iii) 255
(e) Number of candies in 12th row:
a(12) = 3 + (12 - 1)*2 = 3 + 22 = 25Correct choice is (iii) 25

What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
Answer:
771.18
Step-by-step explanation:
The Amount given is 943
13% of amount will be = 943 x 13%
=
Decreasing 13% from 943 we get = 943-122.59
=820.41
Now the ammount = 820.41
for finding the final amount
find 6% of amount (820.41) we get = 820.41x 6%
=
Decreasing 6% from 820.41 we get final amount= 820.41- 49.23
=771.18
so the final amount is 771.18

Reasoning in the diagram at the right, K, L, and M are the midpoints of the sides of AABC. The vertices of the three small purple triangles are the midpoints of the sides of AKBL, AAKM, and AMLC. The perimeter of AABC is 24 cm. What is the perimeter of the shaded region?
Step-by-step explanation:
Notice that KM = 0.5BC, KL = 0.5AC
and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.
Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)
Perimeter of 3 small purple triangles
= 3 * [24cm * (1/4)]
= 3 * 6cm = 18cm.
Hence Total perimeter of shaded parts
= 12cm + 18cm = 30cm.
