Someone please tell me how to do it step-by-step and there’s 2 questions :(
Answer:
1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!
36+57+a=180.
From this, we can figure out a:
a=87
2. The same goes for this one, just a bit different. We write our equation like this:
3x+90=180
we solve this:
3x=90
we divide both sides by 3 and get:
x=30
There is 1/3 of a pizza left to split between 3 of your friends. If you split the pizza equally. What fraction of the pizza will each of your friends get.
Answer:
Each friend will get 1/9 of the pizza (I think).
Step-by-step explanation:
I believe you would divide 1/3 by 3, or in other words, multiply 1/3 * 1/3:
1/3 * 1/3 = 1/9

Answer: the total area is 26 in^2, which is option B
Step-by-step explanation:
ok you have to find the area of the rectangle to the left of the line and then the area of the right triangle and add them together to get the total area
so for the area of the rectangle it would be
a = Lw
a = 4 * 5 = 20 in^2
now to find the area of the triangle we first subtract 5 from 8 to see the lenght of the segment from the vertical line to the vertex of the triangle
8 - 5 = 3
so the segment is 3 inches long
the formula for the area of a triangle is (1/2)bh
(1/2)(3)(4) = 1/2 (12) = 6
so the area of the triangle is 6 in^2
now lets add the area of the rectanglke and the area of the triangle together to find the total area
20 in^2 + 6 in^2 = 26 in^2
the total area is 26 in^2, which is option B
Answer:
B. 26 square inches
Step-by-step explanation:
For the rectangle, 4 times 5 equals 20, then 4 times 3 equals 12 divided by 2 equals 6. 20 + 6 = 26

X=1,
X^2=X,
X^2-1=X-1,
(X+1)(X-1)=X-1,
X+1=1,
X=0
Where is the mastic?
Answer:
You are technically dividing by zero, it breaks math.
In the step (X+1)(X-1)=X-1 → X+1=1.
You divide (X+1)(X-1)=X-1 by (x-1) on both sides to get:
(x+1)(x-1) / (x-1) = (x-1) / (x-1).
Since x = 1,
(x + 1)(x - 1) / (x - 1) = (x - 1) / (x - 1)
becomes (2)(0) / 0 = 0 / 0.
And when you divide by zero, it's undefined since you cannot multiply a number by zero and get a number other than zero, it's undefinable.
This is where limits come in, when you divide by a variable, you have to assumed that is it ≠ 0.
You know that 1 ≠ 2, and 0 ≠ 1, and so on.
As dividing by zero approaches infinity,
1/0.1 = 10, 1/0.01 = 100, 1/0.001 = 1000, 1/0.00..1 = 1000.. → 1/0 → infinity.
1/-0.1 = -10, 1/-0.01 = -100, 1/-0.001 = -1000,
1/-0.00..1 = -1000.. → 1/0 → -infinity.
This suggests that dividing by zero should be infinity.
Therefore infinity = -infinity, Wrong.
When you are dividing, you are really asking yourself, how many times does this number fit into the other number.
1 cannot fit into 0, there isn't anything to fit into. This can also be thought of as:
1 = 0 + 0 + 0 + 0 + 0 + ......
0 + 0 = 0, so 1 ≠ 0.
Answer:
1 cannot = 0, this is like breaking physics.

Answer:
Please find attached the required graph of the equation, y = x² - 2·x - 8, created using MS Excel
Step-by-step explanation:
The given function required to be plot is y = x² - 2·x - 8
Therefore, the coordinates of the vertex of the parabola formed by the equation (h, k) is given as follows;
h = -(-2)/(2×1) = 1
k = 1² - 2×1 - 8 = -9
The coordinates of the vertex = (1, -9)
The roots of the equation is given when y = 0, as follows;
At the roots, we have;
x² - 2·x - 8 = 0
By factorizing, we get
x² - 2·x - 8 = (x - 4)·(x + 2) = 0
Therefore. the roots of the equation are;
x = 4, and x = -2
The coordinates of the roots are;
(4, 0), and (-2, 0)
Two other points can be found at when x = 3 and when x = 0 as follows;
When x = 3, we have;
y = 3² - 2×3 - 8 = -5
(3, -5)
When x = 0, we have;
y = 0² - 2×0 - 8 = -8
(0, -8)
The five points are;
(1, -9), (4, 0), (-2, 0), (3, -5), (0, -8)
The graph of the equation created using MS Excel showing the five points is attached.

Answer:
Step-by-step explanation:
V=H x W x L so 11.25= H (1.5) (2); 3H=11.25 so the height of one box is 3.75’
To find the volume of 5 stacked boxes multiply the volume of one box by 5.
5(3.75 x 1.5 x 2) which is 20.25 cubic feet.
Write an inequality to express the relationship between -8 and -13
Answer:
The inequalities are used as:
a > b (a is greater than b)
a < b (a is smaller than b)
a ≤ b (a is smaller than or equal to b)
a ≥ b (a is greater than or equal to b)
a ≠ b (a is different than b)
Now, let's apply these for our two numbers.
-8 and -13
We know that for negative numbers, the larger absolute value means that the number is smaller, then we relate these numbers in the next 3 ways.
-8 > -13 (-8 is greater than -13)
-13 < 8 (-13 is smaller than -8)
-13 ≠ -8 (-13 is different than -8)

In definitions of angle pair, two given angles cannot be both?
A.adjacent and vertical B.supplementary and congruent
C.adjacent and complementary
D.vertical and congruent
Answer:
A: Adjacent and vertical.
Step-by-step explanation:
When two lines intersect, vertical angles are the angles that are opposite (you can see the draw at the end) such that these two angles are only connected by the intersection point.
And two angles are adjacent if these angles are separated by one of the lines.
Then two angles can't be adjacent and vertical at the same time.
Because if two angles are adjacent, then these angles are separated by one of the lines, thus these angles can't be opposite, concluding that these angles can't be vertical angles.
And if two angles are vertical, the only "contact" point between these angles is the intersection point, then these angles can't be divided by one of the lines, then these angles can't be adjacent angles.
Then the correct option is A: adjacent and vertical.
Find the area of this figure.
Answer:
216 cm^2
Step-by-step explanation:
Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.
14 * 12 = 168
Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.
(8 * 12) / 2
96 / 2
48
Now, combine these two values to get the total:
168 + 48 = 216 cm^2
All done!

When you fill your coffee at a gas station, you're supposed to get 8 ounces of coffee with a standard deviation of .7 ounces. A random sample of 50 "8 ounce" coffees is collected and measured and the mean was found to be 7.8 ounces.
Answer:
The answer is below
Step-by-step explanation:
When you fill your coffee at a gas station, you're supposed to get 8 ounces of coffee with a standard deviation of .7 ounces. A random sample of 50 "8 ounce" coffees is collected and measured and the mean was found to be 7.8 ounces. a) Find a 90% confidence interval. b) Interpret the confidence interval in the context.
Solution:
The confidence = 90% = 0.9, mean (μ) = 7.8 ounces, standard deviation (σ) = 0.7 ounces, sample size (n) = 50
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given by:
[tex]E = z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.65*\frac{0.7}{\sqrt{50} } =0.16[/tex]
The confidence interval = μ ± E = 7.8 ± 0.16 = (7.64, 7.96)
b) This means that we are 90% confident that any selected coffee has a weight between 7.64 ounce to 7,96 ounce

Jose has 200 baseball cards. He has the Topps brand which he paid $1.50 each, Upper Deck Company brand which he paid $5.75 each, and Panini Group brand which he paid $2.60 each. He has 20 fewer Upper Deck Company brand than Panini Group brand. The total amount he spent was $589.50. How many of each brand of baseball cards does he have?
Answer:
Jose has 70 Panini, 50 Upper Deck, and 80 Topps cards.
Step-by-step explanation:
Given that Jose has 200 baseball cards, and he has the Topps brand which I have paid $ 1.50 each, Upper Deck Company brand which I have paid $ 5.75 each, and Panini Group brand which I have paid $ 2.60 each, and he has 20 fewer Upper Deck Company brand than Panini Group brand, and the total amount he spent was $ 589.50, to determine how many of each brand of baseball cards does he have, the following calculation must be performed:
100 Panini + 80 Upper Deck + 20 Topps = X
100 x 2.6 + 80 x 5.75 + 20 x 20 x 1.5 = X
260 + 460 + 30 = X
X = 750
80 Panini + 60 Upper Deck + 60 Topps = X
80 x 2.6 + 60 x 5.75 + 60 x 1.5 = X
208 + 345 + 90 = X
X = 643
60 Panini + 40 Upper Deck + 100 Topps = X
60 x 2.6 + 40 x 5.75 + 100 x 1.5 = X
156 + 230 + 150 = X
X = 536
70 Panini + 50 Upper Deck + 80 Topps = X
70 x 2.6 + 50 x 5.75 + 80 x 1.5 = X
182 + 287.5 + 120 = X
X = 589.5
Therefore, Jose has 70 Panini, 50 Upper Deck, and 80 Topps cards.
