14 - a = 5
-4 - 8n = -100
Answer:
a=9
n=12
Step-by-step explanation:
a=14-5
a=9
8n=100-4
n=96\8
n= 9
14-a=5
-a=5-14
-a=-9
a=9
-4-8n=-100
-8n=-1000+4
-8n=-996
n=-996/-8
n=249/2
Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they each bought their own soda at $2.75 each. How much money did they spend total for their trip to the movies? If they decide to split the bill, how much will they each pay?
Answer:
Total amount spent [tex]=\$73.5[/tex]
If they decide to split the bill, amount paid by each of the person [tex]=\$15.25[/tex]
Step-by-step explanation:
Cost of each movie ticket = $11
Cost of 5 tickets = 5(11)= 55
Cost of each packet of popcorns = $3.75
Cost of two packets of popcorns = $2(3.75) = $7.5
Cost of each soda = $2.75
Cost of five sodas = $5(2.75) = $13.75
Total number of persons (Rachel and four friends) = 5
Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]
If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

what is 1/10 of 4.8
Answer:
0.48
Step-by-step explanation:
Just move back one decimal point of 4.8
Answer: I just did this one lol
Step-by-step explanation:
10 percent *4.8 =
(10:100)*4.8 =
(10*4.8):100 =
48:100 = 0.48
Now we have: 10 percent of 4.8 = 0.48
Question: What is 10 percent of 4.8?
Percentage solution with steps:
Step 1: Our output value is 4.8.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$4.8=100\%$.
Step 4: Similarly, $x=10\%$.
Step 5: This results in a pair of simple equations:
$4.8=100\%(1)$.
$x=10\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{4.8}{x}=\frac{100\%}{10\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{4.8}=\frac{10}{100}$
$ x=0.48$

Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.
Angle one: 2x°, angle two: xº, angle 3: (X + 8)°
Sum of all angles in a triangle = 180°
Which means :-
∠1 + ∠2 + ∠3 = 180°
[tex]2x + x + x + 8 = 180°[/tex]
[tex]4x + 8 = 180°[/tex]
[tex]4x = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]x = \frac{172}{4} [/tex]
[tex]x = 43[/tex]
Angle 1 :-
= 2x
= 2 × 43
= 86°Angle 2 :-
= x
= 43°Angle 3 :-
= x + 8
= 43 + 8
= 51°[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]
Ernie earned $121.50 more than Kaylin. Tria earned $35 less than 3 times the amount Kaylin earned. Ernie, Tria, and Kaylin earned $579 in all. How much did Tria earn?
$98.50
$220.00
$260.50
$330.50
x - Ernie, y - Kaylin, z - Tria
x = y + 121.50
z = 3y - 35
x + y + z = 579
-------------------------
z = 3 y - 35 => - 3 y + z = -35
y + 121.50 + y + z = 579
---------------------------------
- 3 y + z = - 35 / · ( -1 )
2 y + z = 457.50 (we will use the elimination method)
---------------------------------
3 y - z = 35
2 y + z = 457.50
----------------------
5 y = 492.5, y = 492.5 : 5 = 98.5
z = 3 · 98.5 - 35
z = 260.5
Tria earned $260.5

Prove that: (1 + cos A)^2 - (1 - cos A)^2/
sin^2 A=
4cosec A. cotA
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]
Consider the left side
[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator
= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]
= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]
= [tex]\frac{4cosA}{sin^2A}[/tex]
= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]
= 4cosecAcotA
= right side, thus proven

When the transformation (x,y) → (x + 10, y + 5) is
performed on point A, its image, point A', is on the origin
What are the coordinates of A? Justify your answer.
Answer:
its 3.05
Step-by-step explanation:
The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is performed on point A.
Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.
Since the transformation (x,y) → (x + 10, y + 5) is performed on A.
A = (0 - 10, 0 - 5)
If we are going from the pre-image to the image, we will translate to the left and downwards
A = (-10, -5)
Hence the coordinates of A will be at (-10, -5)

If one penny, two dimes, and one quarter are added to the bag, what is the new probability that Marissa will draw a nickel? Write your answer as a fraction, as a decimal, and as a percent. 25% chance. (I gave all info please answer this:
In which situation is it more likely that Marissa will draw a nickel
Answer:
As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%
Answer:
= 1/5
.2
20%
Step-by-step explanation:
In the bag there are 5 pennies, 4 nickels , 5 dimes, 2 quarters
We add 1 penny 2 dimes and 1 quarter
Now in the bag
6 pennies, 4 nickels, 7 dimes, 3 quarters
for a total of 20 coins
P ( nickel) = number of nickels / total
= 4/20 = 1/5
.2
20%
She is more likely to draw a nickel before the 1 penny 2 dimes and 1 quarter because there are fewer coins in the bag that are not nickels
Every musician in the band plays either the flute or the drum (but not both). The ratio of flutists to drummers is 7 : 1. If 2 drummers join the group and 6 flutists quit, the ratio of flutists to drummers would be 3 : 1. How many musicians were in the original ensemble? 4. A sloth is swimming in the Charles River at 20 feet per minute. How fast is the sloth swimming in smoots per hour? One smoot is equal to 5 feet, 7 inches. Write your final answer as a simplified fraction.
Answer:
Number of drummers in original ensemble [tex]=3[/tex]
Number of flutists in original ensemble [tex]=21[/tex]
Step-by-step explanation:
The ratio of flutists to drummers is [tex]7:1[/tex]
Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].
As 2 drummers join the group and 6 flutists quit,
Number of drummers = [tex]x+2[/tex]
Number of flutists = [tex]7x-6[/tex]
New ratio of flutists to drummers = [tex]3:1[/tex]
So,
[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]
So,
Number of drummers in original ensemble [tex]=x=3[/tex]
Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

What does it mean when they ask "What is the domain of f(x)," and the range?
Answer:the domain is all real numbers it also like the x value and the range is all y value
Step-by-step explanation:
Answer:
The domain is the set of values of "x" for which the function has meaning.
Based on my knowledge x can be any real number except for zero.
The range of f(x) is the same as finding all that y could be.
The range of f(x) is all the y values where there is a number x with y = f(x).
