test later and scored 71%. Including Jessica's score, what was the new value of the mean mark?
Answer:
56.5%
[tex] \frac{29 \times 56 + 71}{30 \times 100} = 0.565 = 56.5\%[/tex]

Step-by-step explanation:
The calculations are easily done in a spreadsheet, starting with √A. The value of B is (√A +1)². The formatting of the root as a mixed number is done by converting the numerical values to text strings and joining them together with appropriate intervening characters.
Answering these in this way tends to reduce arithmetic and copying errors. (You may notice that B-A is always 1+2√A.)

Which of the following expressions is equivalent to 4(2x+y) ?
Answer:
what expressions
Step-by-step explanation:
Answer:
Step-by-step explanation:
First expand the expression so you know the coefficients of x and y.
4(2x+y+2y) = 4(2x+3y) = 8x+12y
8x+12y = 8x+12y
6x+7y ≠ 6x+12y
8x+y+2y = 8x + 3y ≠ 8x+12y
8x+4y+8y = 8x+12y = 8x+12y
hope this help

Alice purchased 4 1⁄2 kilograms of olive oil for $27. What is the price per kilogram?
=====================================================
Explanation:
The mixed number 4 & 1/2 converts to the decimal form 4.5
The unit price is 27/(4.5) = 6 dollars per kilogram
------
If you wanted, you can think of it like this ratio
4.5 kg : 27 dollars
Dividing both parts of that ratio by 4.5 will lead to
1 kg : 6 dollars

HELP ME PLEASE I NEED CORRECT ANSWER
Answer:
see explanation
Step-by-step explanation:
The vertex is the coordinates of the turning point of the parabola
The axis of symmetry is a vertical line passing through the vertex with equation
x = c ( where c is the x- coordinate of the vertex )
vertex = (0, 0 ) , axis of symmetry is x = 0 ( the y- axis )
(1)
vertex = (- 2, 4 ) , axis of symmetry is x = - 2
(2)
vertex = (7, 1 ) , axis of symmetry is x = 7
(4)
vertex = (- 3, - 2 ) , axis of symmetry is x = - 3

Find the equation that passes through (2, 2) and is parallel to 2y + 4x = 4.5
Answer:
Line passing through (2,2) is parallel to X - 2Y = 4, so, the slope is same as given line.
m = -a/b = -1/-2 = 1/2
The equation is
(Y - Y1) = m(X - X1) => Y - 2 = 1/2(X - 2) =>
2Y - 4 = X - 2 => | X - 2Y = -2 |
How do I find all the angles?
Step-by-step explanation:
so let's say
•(x + 60) = <a
•2x = <b
so
•<a = <z & <b = <y
&
•<a + <b = 180
(x + 60) + 2x = 180
3x + 60 = 180
3x = 180 - 60
3x = 120
x = 40
• <a = (x + 60)
= 40 + 60
= 100
• <b = 2x
= 2 × 100
= 200
• <y = <b
= 200
• <z = <a
= 100
Step-by-step explanation:
so in a 4 sided figure all the angles measure to 360º in total
as well as in this case due to the two lines being parallel z=x+60 and y=2x
The easiest way for me is to write that all the angles = 360.
x+60+x+60+2x=2x=360
6x+120=300 simplify
6x=180 divide
x=30
so the angles are all 90º if you find each of them

Find the length of the third side. If necessary, round your the nearest tenth.
Answer:
24
Step-by-step explanation:
Use Pythagorean theorem,
base² + altitude² = hypotenuse²
7² + altitude² = 25²
altitude² = 25² - 7²
= 625 - 49
= 576
altitude = √576
altitude = 24
_________
[tex] \: [/tex]
b² = c² - a²
b² = 25² - 7²
b² = 625 - 49
b² = 576
b = √576
b = 24
