Matt has 3 different colored T-shirts and 2 different colored shorts
How many outfits can Matt make with these clothes?
Answer:
Step-by-step explanation:
3 x 2 = 6
Matt can make 6 different outfits with these clothes.
What are the Combinations?Combinations are the procedures used in mathematics to pick k things from n different items without replacement.
The following formula computes the combinations of k items from n:
(n, k) = n! / k!×(n-k)!
Given that Matt has 3 different colored T-shirts and 2 different colored shorts.
Matt can make 3 x 2 = 6 different outfits with these clothes.
This is because for each T-shirt color, he has 2 options for shorts, and he has 3 different T-shirt colors.
So for each T-shirt color, the number of outfit combinations is 2. And since he has 3 T-shirt colors, the total number of outfits is 3 x 2 = 6.

7 cm
40°
Х
Answer:
10.8
Step-by-step explanation:
By sine rule:
[tex] \frac{x}{ \sin 81 \degree} = \frac{7}{ \sin 40 \degree} \\ \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree} \\ \\ x = \frac{7 \times0.9876883406 }{0.6427876097} \\ \\ x = \frac{6.91381838}{0.6427876097} \\ \\ x = 10.755992 \\ \\ x \approx 10.8[/tex]
Using the tangent formula we can write as,
Tan 40° = 7 / x
Tan 40 = 0.84
The value of x is 8.3 cm
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
A triangle with angle 40° angle 81° and 7 cm on on side of the triangle.
Using the tangent formula we can write as,
Tan 40° = 7 / x _____(1)
Now,
Tan 40 = 0.84
From (1) we get,
0.84 = 7 / x
x = 7 / 0.84
x = 8.3 cm
Thus,
The value of x is 8.3 cm

Calculate the mean of 79,58,72,61,80
Answer:
Mean = 70
Step-by-step explanation:
given f(x)=50+30x, find f(1), f(2), and f(3)
Please help
The numbers inside the parentheses are the x values. Replace x with each number and solve.
F(1) = 50 + 30(1)= 50+ 30 = 80
F(2) = 50 + 30(2)= 50 + 60 = 110
F(3) =!50 + 30(3)= 50 + 90 =140
The value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 50 + 30x
The value of the function at x = 1, will be
f(1) = 50 + 30 × 1
f(1) = 50 + 30
f(1) = 80
The value of the function at x = 2, will be
f(2) = 50 + 30 × 2
f(2) = 50 + 60
f(2) = 110
The value of the function at x = 3, will be
f(3) = 50 + 30 × 3
f(3) = 50 + 90
f(3) = 140
Thus, the value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

A chess club plans to sell water bottles to raise $425
they already have $175
if they sell water bottles for $8 each, at least how many bottles do they need to sell in order raise enough money
which inequality represents the situation
Answer:
31
Step-by-step explanation:
I rounded it down thats it
The equality for this equation is
175 + 8b >/= 425
B = number of bottles required to sell. Now, I don't want to give you the answer but I can assist you in easily finding it. Subtract 175 from both sides
8b >/= 250
Now, divide at from both sides and remove the greater than mark which should mean that in the end it should look like it says
**edited** I mean divide 8 from both sides.
b = ?
That is the number of bottles they must sell, if it is a decimal, round it up because there is no such thing as a decimal number for selling water bottles.

Given: P= $10000, r = 5% t = 18 years.

What expressions are equivalent to y4 - 625?
Answer:
option D
Step-by-step explanation:
a² - b² = (a + b) (a - b)
625 = 5 * 5 * 5 * 5 = 5⁴
y⁴ - 625 = y⁴ - 5⁴
= (y²)² - (5²)² {a = y² ; b = 5²}
= (y² + 5²)(y² - 5²)
= (y² + 25)(y² - 5²)
= (y² + 25)(y + 5)(y - 5)

The Capulet's are building a horse stall for their horse, Shaggy. The length, y, of the stall must be more than twice the width, x. However, they only have enough material to build 50 feet of fencing. Write the system of equations or inequalities used to solve it. Identify one option that would meet the criteria.
Answer:
y = 18
x = 7
Step-by-step explanation:
Since the Capulet's only have a total of 50 feet of fencing then that will also be the maximum perimeter of the fence and cannot exceed that value. Therefore, using the information provided we can conclude the following
y > 2x
y + y + x + x <= 50ft
2x + 2x + x + x <= 50ft
Now that we have these equations we can first solve for x and then solve for y
2x + 2x + x + x <= 50ft
6x <= 50ft ... divide by 6
x <= 8.33
y > 2 * 8.33
y > 16.66
Therefore, one possible value would be
