find the value of x. write your answer in simplest radical form. x 9 7

Answer: did anyone find the answer???

Step-by-step explanation:

Answer:

1 set of A= $0.15

1 set of B= $0.20

Total Stamps bought = 37

Total purchase = 37

Let X= Set A of $0.15 each

Y= Set B of $0.20 each

x+y = 37----------X=37-Y

0.15X + 0.20Y = 6.60

0.15(37-Y) + 0.20Y = 6.60

5.55- 0.15Y + 0.20Y =6.60

0.05 Y = 6.60-5. 55

Y=1.05/ 0.05= 21

X= 37-21= 16

Answer:

6 1/4

Step-by-step explanation:

Add up the fabric that she has

3 1/2 + 6 3/4

Get a common denominator

3 2/4 + 6 3/4

9 5/4

9 4/4 + 1/4

10 1/4

Subtract this from the fabric that she needs

16 1/2 - 10 1/4

Get a common denominator

16 2/4 - 10 1/4

6 1/4

Answer: 20 mph

Step-by-step explanation:

Given

The airplane is at a height of 528 ft with a rate of 20 mph

The automobile is also directing east at the rate of 40 mph

at this instant, they are separating by the relative velocity between them

[tex]\Rightarrow v_{rel}=40-20=20\ mph[/tex]

Answer:

y=-3x-1.8

Step-by-step explanation:

y-y1=m(x-x1)

y-(-1.8)=-3(x-0)

y+1.8=-3(x)

y+1.8=-3x

y=-3x-1.8

Answer:

-108

Step-by-step explanation:

(-2)²(-3)³​

When a number has an exponent, it means that the number is being multiplied to itself. For example, in (-2)², it means (-2) multiplied by itself twice since the exponent is 2. And for (-3)³​, it means (-3) multiplied by itself 3 times since the exponent is 3.

= (-2)(-2)(-3)(-3)(-3)

Multiply. Remember that two negative numbers multiplied together make a positive number, and a positive and a negative number multiplied together make a negative.

= (4)(-3)(-3)(-3)

= (-12)(-3)(-3)

= (36)(-3)

= -108

Therefore, the answer is -108.

Answer:

60 books were at the book sale

Step-by-step explanation:

Let

x = total books at the book sale

Percentage of books sold = 80% of x

= 80/100 * x

= 0.8x

Number of books sold = 48

Therefore,

0.8x = 48

Divide both sides by 0.8

0.8x / 0.8 = 48 / 0.8

x = 60 books

x = total books at the book sale = 60 books

Number of books unsold = Total books at the book sale - number of books sold

= 60 - 48

= 12

Number of books unsold = 12 books

Answer:

With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:

C(x)=20+4x,where:

x is the number of rides

The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

Answer:44

Step-by-step explanation:

Just you the proportions:

so you will get (20*33)/15 which is equals to 44

Answer:

44

Step-by-step explanation:

From the one side the relationship is 15:20, so for this side it's 33:??

15/20 = .75

33/.75 = 44

Answer:

The expected payoff for Ann is that she loses the game

Step-by-step explanation:

The expected payoff for Ann is that she loses the game, this is because only 5 out of the 20 sections allow Ann to win money, this is only 25% of the spinner. Meaning that 75% of the spinner will cause Ann to lose the game. Rolling two times increases the odds that she will lose the game. Since the greatest probability is that Ann will land on a section that causes her to lose the game, then this is the expected payoff.

Answer:

x = 42,33°

Step-by-step explanation:

3x + 1° + 52° = 180° [angles on a straight line]

3x + 53° = 180°

3x = 180° - 53°

3x = 127°

divide both sides by 3

x = 42,33°

Answer:

The sound of hammering becomes fainter as Nancy goes into her room because some of the sound waves are absorbed by the walls. Only part of the sound waves coming from the other room comes into her room, so the hammering sounds quieter.

I hope this helps. Good luck ^^

Answer:

Step-by-step explanation:

From the figure

x+159=180°

(linear pair)

x=180-159

x=21°

Answer:

y=-6/5x-2

Step-by-step explanation:

We are given points (5,-8) and (-5,4)

Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5

Y-intercept = b = (0,-2)

Final equation: y=-6/5x-2

Answer:

y=-6/5x-2

Step-by-step explanation:

y=mx+b

Its sloping downwards, so a negative slope.

two points: (-5,4) and (5,-8)

---------------------------------------------

so first find the slope.

y2-y1 / x2-x1  <= formula

so: -8-(4) / 5-(-5)

which becomes => -12/ 10

which is 6/5 the slope is 6/5

------------------------------------------

plug this into y=mx+b, where m is the slope

so: y=6/5x+b

------------------------------------------

obviously b is the y intercept, where the line meets y

the y intercept is -2

sooooooo final answer is

----------------------------------

y=6.5x+(-2)

-----------------------------------

Negative slope, so becomes y=6/5x-2

Answer:

120

Step-by-step explanation:

The probability of a girl being picked one day = 10/15 = 2/3

Total number of days = 180

Therefore, the nunber of times it will be a girl = 2/3 x 180 = 2 x 60 = 120

Answer:

2*x + 2*y ≤ 165 ft

x > 50ft

0ft < y ≤ 20ft

Step-by-step explanation:

For a rectangle with length x and width y, the perimeter of the triangle is:

P = 2*x + 2*y

The perimeter needs to be equal or smaller than the length of fencing that the farmer has, then:

2*x + 2*y ≤ 165 ft

We also know that:

(x strictly larger than 50ft)

x > 50ft

(y can be, at most, 20 ft)

0ft < y ≤ 20ft

(where we added the restriction that y needs to be larger than zero, because we can not have a width equal or smaller than zero)

Then the system of inequalities that represent this situation is:

2*x + 2*y ≤ 165 ft

x > 50ft

0ft < y ≤ 20ft

if you mean that 3x+3=0 then x should equal 0

Answer:

Actually Welcome to the concept of Angles.

Here, total angle is 90°.

hence, 90° = x + 57°

so, ==> x = 90° - 57°

x = 33°

hence, x = 33°

Answer:

x=33°

Step-by-step explanation:

90-57=33. Basically, Q is 90°

Answer:

The midpoint is (-5, -3).

Step-by-step explanation:

Finding the coordinates of the midpoint consists of averaging the x-coordinates of the given points and then doing the same for the y-coordinates.

x coordinate of midpoint = (-9 - 1)/2 = -5

y coordinate = -6/2 = - 3

The midpoint is (-5, -3).
