Answers
Answer:
Step-by-step explanation:
2) They distributed an x out of the term with out one. that is the 8
so the expression should be 5x +8
3) They didn't follow order of operations and took 2 away from the 7 before they distributed the 7 :O very bad of them
the expression should be 7x + 54
4) They distributed out the y but didn't leave a 1 so the problem lost a term.
the expression should be -6x + 7y
14. The figure shows a slice of an apple pie in the shape of a sector of a circle with centre O and radius 8cm. A cut is made along AB to remove some of the crust
Given that AB = 7 cm find:
(i) AOB in radians
(ii) the maximum number of slices that can be obtained from one full pie.
(iii) the area of the shaded segment that has been removed
Answers
Step-by-step explanation:
(i) Using the law of cosines, we can find that
[tex]cos(O) = \frac{8^{2}+8^{2} - 7^{2}}{8*8*2}[/tex] ≈ 0.62, so O ≈ 0.9
(ii) Since the whole pie has 2π radians (or 360 degrees), we can divide 0.9 by 2π to get around 6.9 slices from the pie
(iii) The area of the shaded segment can be found by finding sector OAB and subtracting triangle OAB from that. Sector OAB can be found by finding the area of the pie (π*8², since 8 is the radius) and dividing that by 6.9, so we get 64π/6.9 ≈ 29. Then, the area of the triangle is √p(p-a)(p-b)(p-c), with p being the perimeter and a, b, and c being the sides. Plugging 7, 8, and 8 in, we get 25.1781 as our area, so the difference is around 3.8

film processing costs $4.95, plus $0.35 for each picture printed. Milan paid $11.95 for processing and printing. How many pictures did he have printed?
Answers
Answer:
20 pictures.
Step-by-step explanation:
In this question, we need to find out how many pictures Milan printed.
We know that the film processing costed $4.95 and each picture that was printed costed $0.35.
Lets turn this into an equation with x representing the amount of pictures:
y = 0.35x+ 4.95
Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".
Solve:
11.95 = 0.35x + 4.95
Subtract 4.95 from both sides.
7 = 0.35x
Divide both sides by 0.35
20 = x
Milan printed 20 pictures.

What is the value of the rewritten expression when a = -5?
Answers
Answer:
-500
Step-by-step explanation:
(2a^4)^2
-----------------
a^0 a^5
We know ( xy) ^z = x^z y^z
so
(2a^4)^2 = 2^2 a^4^2
and x^y^z =x^(y*z) so a^4^2 = a^(4*2) = a^8
(2a^4)^2 = 4 a^8
We know that a^0 = 1
4 a^8
-----------------
1 a^5
We know x^y / x^z = x^ ( y-z)
4 a^( 8-5)
4 a^3
Let a = -5

Step-by-step explanation:
For the equation to have more than one solution, that is infinite solutions, then both sides should be equal.
left side is
5u + 3(4u - 6)
= 5u + 12u - 18 = 17u - 18
right side is
- 3u - 27 + 20u
= 17u - 27 ← require to add 9 so equal to left side, that is
17u - 27 + 9
= 17u - 18
George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35 ), and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money.
Answers
Answer:
He does not have enough money
Step-by-step explanation:
Step one:
given data
The total money that Goerge has is $15
Expenses to incure
to see a movie ($9.00) and
to buy a pretzel ($2.65),
a drink ($1.35 ), and
two veggie cups ($1.74 each)= 1.74*2= $3.48
Totoal expenses= 9+2.65+1.35+3.48= $16.48
Step two:
The deficit that George will have is 16.48-15= $1.48
Hence he does not have enough money

Work out m and c for the line:3x+2y-1=0

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation in the standard form is given below.
3x + 2y - 1 = 0
Separate 'y', then we have
3x + 2y - 1 = 0
2y = -3x + 1
y = -(3/2)x + 1/2
Compare the equation with the slope-intercept line.
m = - 3/2
c = 1/2
The value of the slope (m) will be -3/2. And the value of the y-intercept (c) will be 1/2.
