Answer:

{ }, {4}, {6}, {7}, {4, 6} {4, 7}, {6, 7}, {4, 6, 7}

Step-by-step explanation:

The empty set is a subset of every set.

Also, a set is a subset of itself.

S = {4, 6}

T = {6, 7}

S U T = {4, 6, 7}

Subsets of S U T: { }, {4}, {6}, {7}, {4, 6} {4, 7}, {6, 7}, {4, 6, 7}

Answer:

$30.80

Step-by-step explanation:

10% of $28 is 2.80

add 28+2.80=30.80

Answer:

9/20

Step-by-step explanation:

first you have to make 1 1/4 an improper fraction so since the denominator is 4 you add 4 to the numerator which is 1 so your fraction would be 5/4.

Second you make the denominators the same so you have to multiply them together. but since your multiplying the denominators you have to multiply the numerator as well. so for 5/4 you would multiply both the numerator and denominator by 10 so your fraction will now be 50/40. now you  multiply 8/10 by 4 so your new fraction is now 32/40

Third you subtract. you only have to subtract the numerators so 50-32 is 18 so your answer is 18/40

Last you need to simplify the highest number you can divide both of them by is 2 so now you divide 18 by 2 which makes 9 then you divide 40 by 2 which is 20 so your answer is 9/20

Sorry i'm not the best at explaining things but i tried my best

Hope this helps you out and have a great day : )

Answer:

w= -1/3

Let's solve your equation step-by-step.

7w+9−4w−4=4

Step 1: Simplify both sides of the equation.

7w+9−4w−4=4

7w+9+−4w+−4=4

(7w+−4w)+(9+−4)=4(Combine Like Terms)

3w+5=4

3w+5=4

Step 2: Subtract 5 from both sides.

3w+5−5=4−5

3w=−1

Step 3: Divide both sides by 3.

3w/3=−1/3

w= −1/3

Answer:

w= −1/3

Answer:10 adult and 20 children

Step-by-step explanation:

The two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Given that, a hairstylist charges $15 for an adult haircut at nine dollars for a child haircut she wants to earn at least $360.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the number of adults be x and the number of child be y.

So, x+y>30

Now, 15x+9y≤360

⇒ 3(5x+3y)≤360

⇒ (5x+3y)≤120

From the graph we can see that, two graphs intersecting at (15, 15)

Therefore, the two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Answer:

[tex]18\; {\rm in}[/tex].

Step-by-step explanation:

Let [tex](x\; {\rm in})[/tex] be the length of the base.

The question states that the length of each congruent side is [tex]8\; {\rm in}[/tex] less than twice the length of the base. Twice the length of the base would [tex](2\, x\; {\rm in})[/tex]. The length of each congruent side would be [tex](2\, x - 8)\; {\rm in}[/tex].

Sum up the length of each side to find the perimeter of this triangle:

[tex](2\, x - 8) + (2\, x - 8) + x = 5\, x - 16[/tex].

Substitute in the actual perimeter of this triangle:

[tex]5\, x - 16 = 74[/tex].

Solve for [tex]x[/tex]:

[tex]x = 18[/tex].

Therefore, the length of the base of this isosceles triangle would be [tex]18\; {\rm in}[/tex].

Answer:

A

Step-by-step explanation

i = [tex]\sqrt{-1}[/tex]

i² = ([tex]\sqrt{-1}[/tex] )² = - 1

i³ = i² × i = - 1 × i = - i

[tex]i^{4}[/tex] = i² × i² = - 1 × - 1 = 1 , then

[tex]i^{16}[/tex]

= [tex](i^4)^{4}[/tex]

= [tex](1)^{4}[/tex]

Step-by-step explanation:

3/4 = .75

120 * .75 = 90

Of those 90 students 1/3 wore sandals.

90 * .33 = 29.7

Therefore, around 30 students wore jeans and sandals.

Answer:

107.2 seconds

Step-by-step explanation:

Step one:

given

the diameter of ball 8 inches

radius= 8/2 = 4 in

The volume of the ball

[tex]v=4/3 \pi r^3[/tex]

[tex]v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3[/tex]

Step two:

we know that

rate= quantity/time

rate= 2.4 in per second

quantity= 268.12

time=?

time= quantity/rate

time= 268.12/2.5

time= 107.2 seconds
