Answer:
20!
Step-by-step explanation:
Answer:
2880 or 20!
Step-by-step explanation:
Whenever you have a number with a (!) after it, it means that the number is in factorial. So if you have a equation like 3!, it would be equal to 3·2·1. So in that case—
5! = 1·2·3·4·5
We can multiply this sequence of numbers simply.
1·2·3·4·5=120
Now, since we have the first factorial, we move on to the second.
4!=1·2·3·4
Again, we can multiply this sequence simply.
1·2·3·4=24
Now we move on to the final step. We have factoriazed the numbers, so we can substitute those in the equation.
120·24
Now we can finally multiply these 2 numbers to get your answer.
120·24=2880
That is the evaluation.
If you want to simplify the expression, multiply the numbers.
4!·5!=20!

A rectangle is always a square? True or false?
Answer:
False
Step-by-step explanation:
A square is defined as a quadrilateral with 4 congruent sides, but a rectangle is defined as a quadrilateral with 2 pairs of congruent sides, so unless the 2 pairs in a rectangle are the same length, no the rectangle is not a square. However all squares are rectangles.
"A rectangle is always a square" is false statement.
Rectangle:A rectangle is quadrilateral, in which opposite sides are equal in length and all four angles are equal to 90 degree.
A square is quadrilateral, in which all four sides are equal in length and all four angles are equal to 90 degree.
A square is always a rectangle, but a rectangle is not always a square.
Therefore, given statements is false.

Solve for x.
9x - 1 = -11
Answer:
X=-1.1 repeated
Step-by-step explanation:
9x - 1= -11
+1= +1
9x = -10
Divide by 9 on both sides
X = -1.1 repeating
Answer:
- 1 1/9
Step-by-step explanation:
9x - 1 = -11
Add 1 to both sides to eliminate -1 on the left side
9x - 1 + 1 = -11 + 1
9x = -10
Divide both sides by 9 to isolate x
9x/9 = -10/9
x = - 1 1/9

Solve by using Pythagorean Theorem, a= 5, b= x-1, and c=x
The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
Step-by-step explanation:
The given is,
a = 5
b = x - 1
c = x
Step:1
Pythagorean theorem is,
[tex]a^{2} + b^{2} = c^{2}[/tex]................................(1)
( It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides )
From the given values the equation (1) becomes,
[tex]5^{2} + (x-1) ^{2} = x^{2}[/tex]
( [tex](a-b)^{2} = a^{2} + b^{2} -2ab[/tex] )
25 + ( [tex]x^{2}[/tex] + 1 - 2x ) = [tex]x^{2}[/tex]
25 + 1 -2x = 0 ( ∵ Eliminate [tex]x^{2}[/tex] in both sides)
26 = 2x
x = 13
Step:2
From the values of x,
a = 5
b = ( 13 - 1 ) = 12
c = 13
Result:
The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.

Kesha threw her baton up in the air from the marching band platform during practice. The equation h(t) = −16t² + 54t + 40 gives the height of the baton, in feet, t seconds after it is thrown from the platform. What is the height of the platform? At what speed was the baton thrown? If she doesn't catch it, when will it hit the ground?
Answer:
(a)Height of the platform=40 feet
(b)Initial Velocity=54 ft/sec
(c)4 seconds
Step-by-step explanation:
The equation [tex]h(t) = -16t\² + 54t + 40[/tex] gives the height of the baton, in feet, t seconds after it is thrown from the platform.
(a)Height of the platform
The Height of the platform is the height at which t=0
[tex]h(0) = -16(0)\² + 54(0) + 40[/tex]
Height of the platform=40 feet
(b)To determine the speed at which the baton was thrown, we find the velocity, v(t).
[tex]v(t)=\frac{dh}{dt} =\frac{d}{dt} (-16t\² + 54t + 40)=-32t+54\\$At t=0\\v(0)=-32(0)+54=54 feet/sec[/tex]
(c)The baton will hit the ground when its height, h(t)=0
[tex]-16t\² + 54t + 40=0\\\text{Solving the quadratic formular}\\t = \frac{-54\pm \sqrt{(-54)^2 - 4*40*(-16)} }{2*-16}\\= \frac{-54\pm \sqrt{5476 }}{-32}\\= \frac{-54\pm 74}{-32}\\t=\frac{-54+ 74}{-32},\frac{-54- 74}{-32}\\t=-0.625\:or \:t=4[/tex]
Since -0.625 is not valid, the baton will hit the ground 4 seconds after it is thrown.

There are two approaches to solving the equation -3x + 10 = 4x - 20
Subtract 4x from both sides. OR Add 3x to both sides.
-7x + 10 = –20 OR 10 = 7x - 20
Solve the equation using both approaches.
What is the solution?
Answer:
You can take this equation into two approaches.
#1 subtracting 4x from both sides:
-3x+10=4x-20 (subtract 4x from each side)
-7x+10=-20 (then subtract 10 from each side)
-7x=-30 (then divide by -7 to get x by itself)
x=30/7
#2 Add 3x to both sides:
-3x+10=4x-20 (Add 3x to both sides)
10=7x-20 (then add 20 to each side)
30=7x (divide both sides by 7)
30/7=x
Either way you do it you will get x=30/7 as your answer.

Hello
This is a right angle as you can see by the small square at the bottom. So this means that it is 90 degrees.
Because we already know part of the 90 degrees, we can do 90-50 degree which leave us with 40 degrees.
So as we look at 8x, it needs to equal 40
- 8x=40 divide both sides by 8
- x=5

Laura mowed 8 lawns. She earned $12, $10, $15, $15, $15, $10, and $9 for seven lawns. How much did she earn the eighth time if the mean of the data is $12? *
Answer:
She earned $10 for mowing the 8th lawn.
Step-by-step explanation:
Let's use the average formula and n = 8, with x representing the 8th score:
12 + 10 + 15 + 15 + 15 + 10 + 9 + x
average = 12 = -------------------------------------------------
8
86 + x
Summing up the numerator, we get average = ----------- = 12
8
Multiplying both sides by 8 yields 86 + x = 96
Solving for x, we get x = 10.
She earned $10 for mowing the 8th lawn.
Answer:
She earned $10 for the eighth yard.
Step-by-step explanation:
You have 7 known numbers and 1 unknown giving you a total of 8 numbers. When doing mean, you add up all the numbers and divide by the amount of numbers you have (in this case 8). If you add all the numbers in this particular data set you get 86. You know that you have to divide by 8 and you need 12 to be the answer. Using multiplication facts, we know that 96 divided by 8 is equal to 12. That means the answer must be 10 for the eighth yard because 86+10=96.

Step-by-step explanation:
The symbol ≤ means less than or equal to. The symbol ≥ means greater than or equal to.The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b). The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).The five inequality symbols in Maths are greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), and not equal to symbol (≠).

Answer:
41.5 cm^2
Step-by-step explanation:
The area of the right triangle is
A =1/2 bh where b = (2+7) and h=(4+7)
=1/2(9)(11)
49.5
The area of the rectangle is
A = l*w where l is 2 and w is 4
A = 2*4 = 8
The shaded region is the area of the triangle minus the area of the rectangle
A shaded = 49.5 - 8 = 41.5
Which of these equations has a y-intercept of 4?
A. y=x+4
B. y=x-4
C. y=4x
D. y+4=x
Answer:
A
Step-by-step explanation:
Since A is already in slope intercept form, we know that the b value is already in the correct place.
y = mx + b
In slope intercept form, the b is the y int.
Thank me later :)
Answer:
Option A, y = x + 4
Step-by-step explanation:
Step 1: Determine which option is correct
y = mx + b
m is the slope while b is the y-int
So... the equation with a 4 for b should be the correct answer.
Option A states the following: y = x + 4
This shows that the y-int is 4 and the slope is 1. So, this answer is correct.
Answer: Option A, y = x + 4

What is the length of side PQ in this figure?
Answer:
C
Step-by-step explanation:
o find the side PQ ; we need to first find the length of the given line segment which is perpendicular to side PR; let name it as QS.
Now as ΔQSR is an right angled triangle.
and the length of the side QR and SR is given , so using Pythagorean theorem we have
QR^{2}=SR^{2}+QS^{2}
5^{2}=3^{2}+QS^{2}\\ \\QS^{2}=5^{2}-3^{2}\\\\QS^{2}=25-3=16=4^2
⇒ QS=4
Now again ΔQSP is an right angled triangle; so using Pythagorean theorem in ΔQSP we have
PQ^{2}=QS^{2}+PS^{2}\\ \\PQ^{2}=4^{2}+6^{2}=16+36=52
This means QS=\sqrt{52}=2\sqrt{13}
Hence, the length of side PQ is \sqrt{52}=2\sqrt{13}.
Hence, option C is correct.

A private club was reduced by 27 members in 3 weeks. Its size changed by the same number of members each week. What was the change in the club's size each week?
Final answer:
The club's size decreased by a total of 27 members over 3 weeks. By dividing 27 by 3, we find that the size changed by 9 members each week.
Explanation:
The question asks about a private club which lost 27 members over the course of 3 weeks, with an equal number of members leaving each week. To find the change in the club's size each week, we divide the total number of members who left by the number of weeks. This calculation is done by taking the total decrease in members, which is 27, and dividing it by the 3 weeks.
Identify the total decrease in members: 27.
Identify the total number of weeks: 3.
Divide the total decrease in members by the number of weeks: 27 members ÷ 3 weeks = 9 members per week.
Therefore, the club's size changed by 9 members each week.
