Six friends share 2 pumpkin pies equally. What fraction of a pumpkin pie does each friend get?
Answer:
1/3 of the pumpkin pie
Step-by-step explanation:
2 pies can equal 6 pieces, 3 pieces a pie
If their are 6 friends and 3 pieces a pie then then they will have a 1/3 of the pie each
1/3 times 6 equals 6/3, which equals 2 pies
Please help! Pleaseee
Answer: B
Explanation: Input y=2x+5 in both coordinates.
[tex]y = 0 + 5[/tex]

The guest at a party shared five pies equally in each person get 1/8 of a pie how many guest were at the party?
Answer: 40 people
Step-by-step explanation:
There were 5 pies in the party and each person that came got an equal share of 1/8.
The number of people who were there is therefore:
= Number of pies / Share each person got
= 5 ÷ 1/8
= 5 * 8/1
= 40 people

3 times everything in the bracket and 2 times everything in the bracket.
3x(-2x)-6<2x(-2x)+18 take away 2x from both sides
( Opposite operators EG, Add becomes subtract)
x-6(+6)<18(+6) add 6 on both sides
x<24

i need to find x, they're vertical angles
Answer:
x = 16
Step-by-step explanation:
vertical angles are equal
3x = 2x+16
x = 16
Answer: x = 16
Step-by-step explanation:
Since they are vertical angles, we can set them up equal to each other:
3x = 2x + 16
Now, we simply solve for x by subtracting 2x on both sides of the equation.
3x = 2x + 16
x = 16
Kiara said the line with equation 28x - y = -20 has a slope of 28. . What mistake did Kiara make?
Therefore, the mistake Kiara made was to take the absolute value of the slope instead of correctly identifying the slope as a negative value.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equal sign can contain variables, constants, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, exponentiation, logarithms, etc. Equations can have different types of solutions, including real solutions, complex solutions, and no solutions. Equations can be used to model a wide range of mathematical and scientific problems, and they are an essential tool for problem-solving in many fields.
Here,
The equation 28x - y = -20 is in the form of the standard linear equation Ax + By = C, where A, B, and C are constants, and x and y are variables.
To find the slope of a line from an equation in this form, we need to rearrange the equation into slope-intercept form, which has the form y =mx + b, where m is the slope of the line, and b is the y-intercept.
To do this, we need to isolate y on one side of the equation:
28x - y = -20
-y = -28x - 20
y = 28x + 20
Now we can see that the equation is in slope-intercept form, with a slope of 28, not -28 as Kiara thought.
Kiara made a mistake in identifying the slope of the line.

18 percent of people in a city eligible to donate blood actually do. You randomly select four eligible blood donors and ask them if they donate blood. Complete parts (a) through (d) below.
Answer:
[tex]P(x = 1) = 0.3970[/tex]
[tex]P(x = 2) = 0.1307[/tex]
[tex]P(x = 3) = 0.0191[/tex]
[tex]P(x = 4) = 0.0011[/tex]
Step-by-step explanation:
Given
[tex]n =4[/tex]
[tex]p = 0.18[/tex]
Required
(a) - (d)
x | P(x)
0 | 0.452
1 |
2 |
3 |
4 |
To solve (a) to (d), we simply apply the following binomial probability formula
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
Solving (a):
[tex]x = 1[/tex]
So, we have:
[tex]P(x = 1) = ^4C_1 * (0.18)^1 * (1-0.18)^{4-1}[/tex]
[tex]P(x = 1) = ^4C_1 * (0.18)^1 * (1-0.18)^{4-1}[/tex]
[tex]P(x = 1) = 4 * (0.18)^1 * (1-0.18)^3[/tex]
[tex]P(x = 1) = 0.3970[/tex]
Solving (b):
[tex]x = 2[/tex]
So, we have:
[tex]P(x = 2) = ^4C_2 * (0.18)^2 * (1-0.18)^{4-2}[/tex]
[tex]P(x = 2) = 6 * (0.18)^2 * (1-0.18)^2[/tex]
[tex]P(x = 2) = 0.1307[/tex]
Solving (c):
[tex]x = 3[/tex]
So, we have:
[tex]P(x = 3) = ^4C_3 * (0.18)^3 * (1-0.18)^{4-3}[/tex]
[tex]P(x = 3) = 4 * (0.18)^3 * (1-0.18)^1[/tex]
[tex]P(x = 3) = 0.0191[/tex]
Solving (d)
[tex]x = 4[/tex]
So, we have:
[tex]P(x = 4) = ^4C_4 * (0.18)^4 * (1 - 0.18)^{4-4}[/tex]
[tex]P(x = 4) = 1 * (0.18)^4 * (1 - 0.18)^0[/tex]
[tex]P(x = 4) = 0.0011[/tex]

What is the width of the dance floor?
Enter your answer in the box
Answer:
12 is the width
Step-by-step explanation:
1. To solve this problem we must first set up an equation:
96a=8l ×?w
2. this is what this equation means 96(area) equals 8(length) times what(width)
3. so we must find out what we must multiply by 8 to get 96
4. to do this we will divide 96 by 8
which equals 12!

What is the area of this figure?
2 mm
5 mm
9 mm
2 mm
5 mm
11 mm
4 mm
Answer:
[tex]68.28[/tex]
Step-by-step explanation:
We can break this figure up into 2 rectangles, and 1 semi-circle.
Let find the area of top rectangle.
Area of rectangle is length x width.
The length is 9 and the width is 2.
9x2=18
so the top rectangle area is 18.
Now let find the lower rectangle area
The lower rectangle length is 4 and the width is 11.
So the area is 44.
Now let find the area of the semi circle.
We need to find the diameter of the circle.
The circle coincides with the side of the lower rectangle.
Since opposite sides in rectangle are equal, the right side of the rectangle also measures 11.
The top right side of the figure measure 5 while the bottom measure 2 so we set up an equation
[tex]5 + 2 + x = 11[/tex]
[tex]7 + x = 11[/tex]
[tex]x = 4[/tex]
So our diameter of the circle is 4.
Area of semi circle is
[tex] \frac{1}{2} \times (\pi) \times {r}^{2} [/tex]
where r is the radius.
Since the diameter is 4 and radius is half of the diameter, the radius is 2.
Plug 2 in the equation
[tex] \frac{1}{2} \times \pi \times {2}^{2} [/tex]
[tex] \frac{1}{2} \times \pi \times 4[/tex]
[tex]2\pi[/tex]
[tex]6.28[/tex]
Now let add all the areas,
[tex]18 + 44 + 6.28[/tex]
[tex]68.28[/tex]
If P=(2,-1),find the image of P under the following rotation. 180 degrees counterclockwise about the origin
9514 1404 393
Answer:
(-2, 1)
Step-by-step explanation:
Rotating a point 180° about the origin in either direction is equivalent to reflecting it across the origin. The effect is to negate both coordinates.
(x, y) ⇒ (-x, -y) . . . . . rotation 180°
(2, -1) ⇒ (-2, 1) . . . . . P' rotated 180° from P
The coordinates of the rotated point are (-2, 1).

I BET NO ONE KNOWS THIS y varies jointly as x and z. y=20 when x=2 and z=5 . Find y when x=3 and z=6
Hello!
If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.
To give you a visual, this is what I mean.
[tex]y=kxz[/tex]
That means we'll want to find [tex]k[/tex] with the first point we're given: [tex](2,20,5)[/tex]
[tex]20=k(2)(5)[/tex]
[tex]20=10k[/tex]
[tex]k=2[/tex]
Which means our equation is:
[tex]y=2xz[/tex]
Now, let's plug in the [tex]x[/tex] and [tex]z[/tex] from the other point to find [tex]y[/tex].
[tex]y=2(3)(6)[/tex]
[tex]y=36[/tex]
Hope this helps!

x²-2x solve for Algebra
Answer:
Step-by-step explanation:
x^2-2x
x(x-2)
Answer:
Presumably you want to factor this, as there is no full equation to solve.
In this case you can divide both terms by x, giving you:
x(x - 2).
If you want to factor it into binomials, that's easy enough, as this is very close to being a difference of squares:
(x + x√2)(x - x√2)
You could just factor x out of both terms as well, giving you
x(x - 2)
