What is the value of the expression (x – y)2 when x = 5 and y = -1
A. 36
B. 16
C. 4
D. 24
Answers
Answer:
36
Step-by-step explanation:
You are given an expression and values to be put into it.
Simply substitute the values in instead of [tex]x[/tex] and [tex]y[/tex].
[tex](x-y)^2[/tex]
When [tex]x=5[/tex] and [tex]y=-1[/tex]:
[tex](5-(-1))^2 = (5+1)^2=(6)^2=36[/tex] - Note: Be careful with negative signs here. Two negatives make a positive.

3/4m(4m+16n) + m/n open the bracket of equation,
3/4m(4m+16n) + m/n = 3+ 12n/m + m/n

You bought a new water glass. The glass is cone-shaped and has a circular base. It has a
diameter of 3 inches and a height of 7.5 inches. What is the volume of the glass? Use 3.14 to
approximate pi. Round your answer to the nearest tenth.
Answers
Answer:
TO find the answer, first you have to find the formula for volume of a cone-
The formula is
V= 1/3 times base times height
So V= (1/3) (pi3^2) (12)
V= 113.04
By the way for the base you have to find the volume of a circle. I divided the diameter by 2 to find the radius.
and pi is 3.14
A ladder leans against the wall of a building. The ladder measures 66 inches and forms an angle of 45 degrees with the ground. How far from the ground, in inches, is the top of the ladder? How far from the wall, in inches, is the base of the ladder?
Answers
Answer:
46.67 in
46.67 in
Step-by-step explanation:
the value of the hypotenuse (length of the ladder ) is given. We are to determine the value of the opposite side (distance from the ground) and adjacent side ( distance from the wall)
(distance from the ground = sin 45 = opposite / hypotenuse
0.7071 = x/66
x = 66 x 0.7071 = 46.67
distance from the wall = cos 45 = adjacent / hypotenuse
0.7071 = x/66
x = 66 x 0.7071 = 46.67

Many games involve chance and they usually involved either dice or cards. For this activity, we will look
at a common game called 7‐11 where two dice are rolled. If the roll adds up to 7 or 11, the player wins.
If the roll adds up to 2, 3, or 12, the player loses. If there is any other sum, it is a draw (no winner or
loser). Use this two‐dice roll scenario to complete the problems below.
. What is the probability for each of the sums below? NOT A MULTIPLE CHOICE.
2=
3=
7=
11=
12=
Answers
Answer:
See below.
Step-by-step explanation:
See the attached chart that shows all outcomes for two dice.
There are 36 possible outcomes, all equally likely (if the dice are fair!).
The probability of getting a sum of 2 is 1/36 (only one way to get 2: both dice show 1).
The probability of getting a sum of 3 is 2/36 = 1/18.
The probability of getting a sum of 7 is 6/36 = 1/6 (the most likely sum!)
(Notice how all the sum = 7 outcomes like on a diagonal in the chart?)
The probability of getting a sum of 11 is 2/36 = 1/18.
The probability of getting a sum of 12 is 1/36.

Answers
Let the three items be M, Y and P.
n{M ∩ Y} only = 4-3 = 1
n{M ∩ P) only = 5-3 = 2
n{ Y ∩ P} only = 2
n{M} only = 12-(1+3+2) = 6
n{Y} only = 10-(1+2+3) = 4
n{P} only = 14-(2+3+2) = 7
n{M∩P∩Y} = 3
Number of women in the group = 6+4+7+(1+2+2+3) as above =25 women.

Based on the areas of the squares determine whether the triangle shown is a right triangle
Answers
Answer:
The answer is "triangle ABC is not a right triangle".
Step-by-step explanation:
For a right-angle triangle:
Its square upon on longest or triangular edges is equivalent to the total of the other two squares
Its parameters indicated throughout the question are;
Square of lateral length [tex]A = 7 \ inch^2[/tex]
The square of lateral length [tex]B = 18 \ inch^2[/tex]
The square of lateral length [tex]C=27\ inch^2[/tex]
Thus, the longest side is C, as well as the size [tex]inch^2[/tex] of the squares of its two sides, is[tex]7 + 18 = 25 \ inch^2[/tex], lower than square [tex]C = 27\ inch^2[/tex], hence, the ABC triangle is not correct. Its longest edge is consequently C.
Determine the equation of the circle graphed below.
Answers
We need to determine the equation of the circle graphed in the attachment. Firstly we know the Standard equation of a Circle as ,
[tex]\sf\implies (x-h)^2+(y-k)^2 = r^2[/tex]
Where ( h , k ) is centre and r is radius.Let's find out the radius . As ,
[tex]\sf\implies r = \sqrt{ ( 6-4)^2+(2+2)^2} \\\\ \sf\implies r =\sqrt{ 2^2 + 4^2}\\\\\sf\implies r = \sqrt{ 4 + 16 }\\\\\sf\implies \red{r =\sqrt{20}}[/tex]
Substituting the respective values :-
[tex]\implies ( x - 4 )^2 + \{y - (-2)\}^2 = (\sqrt{20})^2 \\\\\sf\implies ( x - 4 )^2 + \{y + 2 \}^2 = 20 \\\\\sf\implies x^2+16-8x + y^2+4+4y = 20 \\\\\sf\implies \red{x^2+ y^2 - 8x + 4y = 0 }[/tex]
Answer :-[tex]\boxed{\pink{\tt Equation \to x^2+ y^2 - 8x + 4y = 0 }}[/tex]

Use elimination to find the solution to the system of equations. 9r + 2y = 59
2r + 5y = 4
A. I = I = 7, y = -2
В. 1 41 I = 2 , Y = 9
C. I = 5, y 14 5 55
D. 1 = 9, y = 2
Answers
Answer:
r = 7
y = -2
Step-by-step explanation:
9r + 2y = 59 (Multiply this by 5)
2r + 5y = 4 (Multiply this by -2)
45r + 10y = 295
-4r - 10y = -8
41r = 287
r = 7
2r + 5y = 4
2(7) + 5y = 4
14 + 5y = 4
5y = 4 - 14
5y = -10
y = -2
