Step-by-step explanation:

Joe has 56 possible different outfits.

A combination is a mathematical method in which the number of possible ways in which a set of given items can be chosen, such that the order in which it happens does not matter items.

Joe has 7 different choices for shirts.

Joe has 4 different choices for pants.

Joe has 2 different choices for shoes.

This means that number of combinations in which Joe can choose an outfit can be found by multiplying all the choices.

This can be done as shown below:

Number of choices for shirts * Number of choices for pants * Number of choices for shoes

= 7 * 4 * 2

= 56 combinations.

Therefore, we have found that Joe has 56 possible different outfits. The correct answer is option D.

Answer:

Tuesday, 1: 30 pounds

Tuesday, 2: 40% of the apples

Tuesday, 3: x ( or any variable) + 8

Tuesday, 4: 9a-3b

Step-by-step explanation:

Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.

38%=.38

.38 x 78=29.64

29.64 rounded = 30

If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.  

5/5-3/5 = 2/5

2/5 x 20/20 = 40/100

40/100 = 40%

The unknown score would become a variable, and since its increasing by 3 it is +8.

Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.

3a - b + 3a - b + 3a - b

9a - b - b - b

9a - 3b

72% of students chose burritos

Step-by-step explanation:

first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14

then you would take that number and subtract it from the total of all students: 50-14=36

and then you would take that number and divide it by 50: 36/50=.72

turn that into a percent and you'd get 72%

Answer:

y = 90°

Step-by-step explanation:

y + x = 110° because the sum of two interior angles is equal to an interior angle

x + 70° = y ➡ y - x = 70°

y + x = 110°

y - x = 70° add two equations

2y = 180° (x eliminated -x)

y = 90°

Answer:

12 miles

Step-by-step explanation:

A right triangle is formed, where the distance between the library and the courthouse is one leg ( = 9 miles), the distance between the library and the swimming pool is the other leg (let's call it x), and the distance between the swimming pool and the courthouse is the hypotenuse ( = 15 miles).

From Pythagorean theorem:

15² = 9² + x²

225 - 81 = x²

x = √144

x = 12 miles

Answer: 16.1

Step-by-step explanation:

x^2 = 8^2 + (28/2)^2

x^2=64 + 196

x^2= 260

Take the square root of 260 and get 16.1!

The value of x is x=16.1

The perpendicular from the center of a circle bisects the chord

A line from the center of the circle to the circumference of the circle is the radius of the circle

Lets connect the center of the circle to the other end of the chord that is at the circumference of circle

The diagram attached below

The line OA from the center bisects the chord

AB= half of 28 = 14

the triangle AOB forms a right angle triangle

apply Pythagorean theorem to find out the value of x

[tex]x^2=8^2+14^2\\x^2= 64+196\\x^2=260\\\sqrt{x^2}=\sqrt{260} \\ x=16.1[/tex]

The value of x is 16.1

Answer:

3 * 5 ^ (n-1)

Step-by-step explanation:

3 is the first term and it multiplies by 5

The explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

The standard explicit formula for  a geometric sequence is expressed as:

[tex]T_n = ar^{n-1}\\[/tex]

a is the first term

r is the common ratio

n is the number of terms

Given the sequence of numbers 3, 15, 75, 375...

r = 15/3 = 75/15 = 5

a = 3

Substitute the given parameters into the formula to have:

[tex]T_n = ar^{n-1}\\T_n=3(5)^{n-1}[/tex]

Hence the explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

Step-by-step explanation:

A slope is found using the formula rise (change in y) over run (change in x). The change in x is 0, and the change in y is -2. The answer is -2/0, but dividing by 0 gives you undefined. Don't believe me? Look at the attached image.

Answer:

Undefined

Step-by-step explanation:

Use the formula:

[tex]m=\frac{y+2-y_1}{x_2-x_1}[/tex]

Plug in the numbers/coordinates accordingly:

[tex]m=\frac{6-8}{2-2}[/tex]

[tex]m=\frac{-2}{0}[/tex]

m = undefined

When x = 0, the slope is undefined.
