Suzan bought some balloons and repacked them for sale. He threw away 76 balloons each. Each packet was sold at $86. After sellin

In-s [12.5K]

Answer:

188 balloons

Step-by-step explanation:

First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:

9632 / 86 = 112 balloons

She sold 112 balloons.

We know that she threw 76 balloons away, therefore, the number of balloons she bought was:

112 + 76 = 188 balloons

The domain for f(x) and g(x) is the set of all real numbers. let f(x) = 3x + 5 and g(x) = x2. find g(x) − f(x). x2 − 3x − 5 3x3

Karo-lina-s [1.5K]

F (x)=3x+5
g (x)=x^2

g (x)-f (x)=(x^2)-(3x+5)
=x^2-3x-5

The union of two events A and B is the event that: a) The intersection of A and B does not occur. b) Both A and B occur. c) Eith

Wewaii [24]

Answer:

c) Either A or B or both occur.

Step-by-step explanation:

Suppose that we have two events

Event A

Event B

We have that:

$A = a + (A \cap B)$

In which a a happens and b does not and $A \cap B$ is the probability that aboth events happen

By the same logic, we have that:

$B = b + (A \cap B)$

The union of events A and B is:

$(A \cup B) = a + b + (A \cap B)$

Which includes either one of them or both.

So the correct answer is:

c) Either A or B or both occur.

McNeal stands at the 40 degree angle and is trying to find the width of the river. McNeal knows she is 120 feet from the tree.

Kaylis [27]

Answer:

Our equation is:

$\displaystyle \sin(40^\circ)=\frac{w}{120}$

Solving this yields that the width of the river is about 77 feet.

Step-by-step explanation:

Part A)

We know that McNeal is 120 feet from the tree. This is the hypotenuse.

And we want to find the width of the river, which is the side opposite from our angle.

Since we want to find the side opposite to our angle and we are given the hypotenuse, we will use the sine ratio:

$\displaystyle \sin(\theta^\circ)=\frac{\text{opposite}}{\text{hypotenuse}}$

Our angle is 40°.

The opposite side is unknown. We can let this be w to represent width.

The hypotenuse is 120 feet. Hence, our equation is:

$\displaystyle \sin(40^\circ)=\frac{w}{120}$

Part B)

Solve for w:

$w=120\sin(40^\circ)$

Use a calculator:

$w=77.1345...\approx 77\text{ feet}$

The width of the river is about 77 feet.

Could you help please i will give points but please explain

Leno4ka [110]

Answer: 7/12

Step-by-step explanation: Given that,

(5/6) - (1/4) = ?

The difference Will be, take L.C.M. of 6 and 4 which is 12, then we get,

= ( 10 - 3 ) / 12

= 7 /12
