Answer: 529 possible outcomes
Step-by-step explanation:
You square the number of games as many times as the outcomes (win or loss)
2 outcomes = 23 * 23
23 * 23 = 529
Since there are 2 outcomes, you multiply 2 23’s together to get the number of possible ways.

8a - (8a - 8) is equivalent to 8
Answer:
True
Step-by-step explanation:
Apply the distributive property
8a-(8a)- -8
Multiply 8 by -1
8a-8a- -8
Multiply -1 by -8
8a-8a+8
Simplify by adding terms
Subtract 8a from 8a
0+8
Add 0 and 8
8

Find the slope of the line y=5x+4
Answer:
Slope = 5
Step-by-step explanation:
y = mx + b
m = slope
Slope = 5
Answer:
5
Step-by-step explanation:
Since this is written in slop-intercept form (y = mx + b where m is slope and b is y-int.) the slope is 5.
Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 26, the length of A C is 10, and the length of B C is 24. Given right triangle ABC, what is the value of tan(A)? Five-thirteenths Twelve-thirteenths Twelve-fifths Thirteen-twelfths
Answer:
The right option is twelve-fifthsStep-by-step explanation:
Given a right angle triangle ABC as shown in the diagram. If ∠BCA = 90°, the hypotenuse AB = 26, AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
The right option is therefore twelve-fifths
Answer:
The correct answer is option C. 12/5
Step-by-step explanation:

Step-by-step explanation:
A ramp into a building forms a 6° angle with the ground. If the ramp is 8 feet long, how far away from the building is the entry point of the ramp? Round the solution to the nearest hundredth.
Answer:
7.96 ft
Step-by-step explanation:
Given;
Length of ramp L = 8 ft
Angle with the horizontal (ground) = 6°
Applying trigonometry;
With the length of ramp as the hypothenuse,
The horizontal distance d as the adjacent to angle 6°
Since we want to calculate the adjacent and we have the hypothenuse and the angle. We can apply cosine;
Cosθ = adjacent/hypothenuse
Substituting the values;
Cos6° = d/8
d = 8cos6°
d = 7.956175162946
d = 7.96 ft
The building is 7.96ft away from the entry point of the ramp.
a rectangular inflatable swimming pool is 2 [tex]\frac{4}{5}[/tex] yards long, 2 yards wide, and [tex]\frac{3}{5}[/tex] yard tall. What is the volume of the pool? Round to the nearest tenth
Answer:
3.4 yd^3
Step-by-step explanation:
The volume is
V = l*w*h
V = 2 4/5 * 2 * 3/5
Changing the mixed number to an improper fraction
2 4/5 = ( 5*2+4)/5 = 14/5
V = 14/5 * 2 * 3/5
= 84/25
Changing back to a mixed number
3*25 = 75 with 9 left over
3 9/25
3.36 yd^3
To the nearest tenth
3.4 yd^3
Answer: 3.4 yards cubed, after rounding.
Step-by-step explanation:
To find the volume of a rectangular prism, use the following formula:
[tex]V = wlh[/tex], where w is the width, l is the length, and h is the height
Substitute the values given to you into the formula:
[tex]V = 2 * \frac{3}{5} * 2\frac{4}{5}[/tex]
Simplify the mixed number by multiplying both the numerator and denominator of 2/1 by 5 to get 10/5 and add it to the fraction to get 14/5.
[tex]V = \frac{2}{1} * \frac{3}{5} * \frac{14}{5}[/tex]
Now, multiply the numerators and denominators of the fractions and simplify:
[tex]V = \frac{2 * 3 * 14}{5 * 5}\\\\V = \frac{84}{25}\\\\\\V = 3.36[/tex]
The volume is 3.36 yards cubed. Round to the nearest tenth to get 3.4 yards cubed.
please answer asap! A couple plans to have 5 children. The gender of each child is equally likely. Design a simulation involving 125 trials that you can use to model the genders of the children. Write your answers as numbers.
Step-by-step explanation:
The gender of a child which is either a boy or a girl is determined by the XX-chromosomes, or XY-chromosomes.
Since the couple plan to have 5 children, the chance of a child being a boy is equal to the chance of it being a girl - the chances are 50/50.
What we do to achieve our aim is to run a simulation that would add an X or Y to an X for all 5 children.
Doing this 125 times, we obtain the number of trials we desire.
For each trial, we get for each child, C:
C1: X + (X or Y)
C2: X + (X or Y)
C3: X + (X or Y)
C4: X + (X or Y)
C5: X + (X or Y)
Since the chance of having an X is equal to the chance of having a Y, they equal probability, which is 0.5 for each.

Explain how the Distributive Property can be used to expand the expression on the left side of the equation.
3(x + 4) = 36.
A. Add 3 to each term inside the parentheses.
B. Subtract 3 from each term inside the parentheses.
C. Multiply each term inside the parentheses by 3.
D. Divide both terms inside the parentheses by 3.
Answer:
C
Step-by-step explanation:
The 3 is directly outside the parentheses, meaning you need to distribute the 3 to the x and the 4 because they are inside the parentheses. There is no addition, subtraction, or division involved in this so C is correct.

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
-5
-2
Ο Ο Ο Ο
2
5
Answer:
At x = -2 the graph of this polynomial will touch the x-axis.
Step-by-step explanation:
Recall the behavior difference between power functions of even and odd power. Odd powers are associated with the crossing of the x-axis, while even powers are associated with "touching" of the x axis.
in this cases, since they give you the function in factor form, the actual roots (x-values where the function adopts value zero) of the function are evident :
[tex]f(x)=(x-5)^3\, (x+2)^2[/tex]
It has a root at x = 5 [notice that at such x-value the factor (x-5) becomes zero], and this root is of multiplicity "3" (given by the power associated with the binomial factor for this root)
and has another root at x = -2 [notice that at such x-value the factor (x+2) becomes zero], and this root is of multiplicity "2" (given by the power associated with the binomial factor for it)
It is just the second root analyzed the one that shows an even power (2) associated to its binomial factor, and therefore it is at x= -2 that the graph of this function will show as "touching" the x axis.

Answer:
0, 1
Step-by-step explanation:
The discriminant is b² - 4ac where we have ax² + bx + c, in this case a = -4, b = 12, c = -9 so D = 12² - 4(-4)(-9) = 0.
Because the discriminant is 0 that means that f(x) only has one solution for x meaning that it has only 1 x-intercept.
IThe first three terms of a sequence are given. Round to the nearest thousandth (if
necessary).
72, 24, 8, ...
Find the 8th term.
Answer: the eight term is 8/243
Step-by-step explanation:
Each term in this geometric sequence is equal to the previous term, divided by 3.
72,24, 8
a = 72, r = 1/3
a = first term, r is common ratio
tn = ar^n-1
t8 = 72÷ 3^8–1
t8 = 72÷ 3^7
= 72/ 3^7
= 8/243

Answer:
C. 2 1/2
Step-by-step explanation:
Since there is a distance of 6 1/2 units, you have to add and subtract 6 1/2 from the number.
-4 - 6 1/2 = -10 1/2
-4 + 6 1/2 = 2 1/2
Looking at the answer choices, 2 1/2 can represent point Q.

Please help ASAP! Which ordered pair is a solution of this
equation?
-5x - 9y = -8
Click on the correct answer
A.
(2,-1)
B.
(-1,2)
C.
(-22)
D.
(2,-2)
========================================================
Explanation:
For each possible answer choice, you'll plug in the given coordinates to see which results in a true equation or not.
If we try choice A, then we plug in x = 2 and y = -1 to get
-5x-9y = -8
-5(2)-9(-1) = -8
-10+9 = -8
-1 = -8 which is false
So (x,y) = (2,-1) is not a solution. We can cross choice A off the list.
You'll find a similar situation happens with choices B and D. They don't work either.
-------
Choice C works because...
-5x-9y = -8
-5(-2)-9(2) = -8 .... replaced x with -2, replaced y with 2
10-18 = -8
-8 = -8
We get a true equation. So (-2,2) has been confirmed to be a solution.

The perimeter of the given triangle is
Answer:
~73.68
Step-by-step explanation:
In the right triangle with one angle = 45 deg
=> Isosceles right triangle
=> a = b = hypotenuse/sqrt(2) = (12sqrt(2))/sqrt(2) = 12
In other right triangle with 3 sides are a, c, and d, we have:
sin (30 deg) = a/d
=> d = a/sin(30 deg) = 12/(1/2) = 12 x 2 = 24
Othwise, cosine (30 deg) = c/d
=> c = d x cos(30 deg) = 24 x sqrt(3)/2 = 12sqrt(3)
=> The perimeter of the biggest triangle is calculated by:
P = 12sqrt(2) + b + c + d = 12sqrt(2) + 12 + 12sqrt(3) + 24 = ~73.68
Hope this helps!
