Use the fundamental counting principle to find the total number of outcomes in each situation. Selecting a year in the last decade and a month of the year.
Answer:
120 different outcomes
Step-by-step explanation:
Selecting a year in the last decade ; this means selecting a year from from the last decade :
Number of years jn decade = 10
Selecting a month of the year : number of months in a year = 12
Hence, we have :
10 * 12 = 120 different outcomes

Answer:
[tex]\$843.67[/tex]
Step-by-step explanation:
Let's break the price changes down:
Initial price: $896
On sale for 12%, meaning the computer will be 100-12=88% of the original price:
New sale price [tex]\implies896\cdot 0.88=\$788.48[/tex]
Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.
Final price [tex]\implies 788.48\cdot 1.07\approx \boxed{\$843.67}[/tex]

A rectangle is 2x-3 in by 3x-1 in. Find the area.
Answer:
[tex]\huge\boxed{A=6x^2-11x+3;\ \text{for}\ x>1.5}[/tex]
Step-by-step explanation:
The formula of an area of a rectangle:
[tex]A=a\cdot b\\\\a,\ b-\text{sides of a rectangle}[/tex]
We have:
[tex]a=2x-3\\b=3x-1[/tex]
The domain:
[tex]2x-3>0\ \wedge\ 3x-1>0\\\\2x-3+3>0+3\ \wedge\ 3x-1+1>0+1\\\\2x>3\ \wedge\ 3x>1\\\\\dfrac{2x}{2}>\dfrac{3}{2}\ \wedge\ \dfrac{3x}{3}>\dfrac{1}{3}\\\\x>1.5\ \wedge\ x>\dfrac{1}{3}\Rightarrow\boxed{x>1.5}[/tex]
Substitute:
[tex]A=(2x-3)(3x-1)[/tex]
use FOIL: (a + b)(c + d) = ac + ad + bc + bd
[tex]A= (2x)(3x)+(2x)(-1)+(-3)(3x)+(-3)(-1)\\\\A=6x^2-2x-9x+3[/tex]
combine like terms
[tex]A= 6x^2+(-2x-9x)+3\\\\A=6x^2-11x+3[/tex]
Answer:
6x² - 11x + 3
Step-by-step explanation:
To find the area of a rectangle, we multiply the length by the width.
A = l • w
length: 2x-3
width: 3x-1
A = (2x-3) • (3x-1)
To multiply these two binomials, we must FOIL (first | outer | inner | last) them.
F: 2x • 3x = 6x²
O: 2x • -1 = -2x
I: -3 • 3x = -9x
L: -3 • -1 = 3
Combine the terms.
6x² - 2x - 9x + 3
Combine like terms.
6x² - 11x + 3
This is your area.

The numerator of fraction is 1 less then its denominator if the numerator is increased by 5 the new fraction becomes equivalent to 4/5 what is the original factor?
Answer:
4/5
Step-by-step explanation:
the numerator of fraction is 1 less than its denominator. If the numerator is increased by 4 and the denominator is increased by 5, the new fraction becomes equivalent to 4/5. what is the original fraction?
Let n = numerator
d = denominator
n = d - 1
[tex]\frac{d - 1}{d}[/tex]
[tex]\frac{d - 1 + 4}{d + 5}[/tex] = [tex]\frac{4}{5}[/tex]
[tex]\frac{d + 3}{d+ 5}[/tex] = [tex]\frac{4}{5}[/tex]
cross multiply
5(d + 3) = 4(d + 5)
5d + 15 = 4d + 20
d = 5
n = d - 1
5 - 1 = 4
original fraction 4/5

Answer:
15, 80
Step-by-step explanation:
1) I am assuming the first picture is a 90 degree angle total, because the question can't be solved without that assumption.
90 - 75 = 15
x = 15
2) The whole angle is 180 so 180 - 75 - 25 = CAD
CAD = 80
Answer:
15° and 80°
Step-by-step explanation:
for the first one since its a right angle then its equal to 90 degrees
90-75 = 15 x=15°
for the second one since the line is a straight line then put it equal to 180
25+75+x=180
100+x=180
x=80°

Wildlife reserve has 7 lion cubs born in the spring and now has 41 total lions. Write an equation to represent the situation.
Answer:
(x + 7) = 41
Step-by-step explanation:
Let the number of lions in the wildlife reserve = x
Since, 7 lion cubs were born, so the total number of lions in the wildlife reserve will be (x + 7)
Now total number of lions = 41
Therefore, equation representing this situation will be,
(x + 7) = 41
A youth club leader plans a walk to raise money for charity. The route measures 40 centimeters on a map. The scale on the map is 5 centimeters to 1 kilometer. How long is the actual route?
Answer:
8 km
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
40 / 5 = 8km

You roll a cube with the numbers 13, 16, 18, 20, 22, and 24 on it. You then spin a spinner which has 6 sections. The letters on the spinner are E, B, G, K, D, and H. Find the P(G and prime number). Write your answer as a fraction or a decimal
===========================================================
Explanation:
The only prime number of the list of values given is the value 13. This is because the only factors are 1 and 13. Something like 24 isn't prime because 2 is a factor.
The probability of rolling to get a prime number is 1/6 because there is one prime out of 6 total values listed.
The probability of spinning on "G" is also 1/6 because there is only one section labeled "G" out of 6 sections total.
Assuming both events are independent, we multiply the probabilities to get (1/6)*(1/6) = 1/36 which represents the probability of rolling a prime number and spinning on G.
Side note: 1/36 = 0.0278 = 2.78% approximately
Solve by substitution. Please show work
-x+9y=-5
x-5y=1
Let's solve for x.
−x+9y=−5
Step 1: Add -9y to both sides.
−x+9y+−9y=−5+−9y
−x=−9y−5
Step 2: Divide both sides by -1.
−x ÷ −1 = −9y−5 ÷ −1
x=9y+5
THE ANSWER FOR THE OTHER EQUATION: (x-5y=1)
Let's solve for x.
x−5y=1
Step 1: Add 5y to both sides.
x−5y+5y=1+5y
x=5y+1
Answer:
x=5y+1
