Solve the system.
y = -x +3
2x + 2y = 4

Answers

Answer 1

Answer:

no solution

Step-by-step explanation:

So first, you want to have one of the variables able to cancel out when you add the equations together.

To do this, divide the second equation by two

2x+2y=4

divide by 2

x+y=2

Next, get the variables on the same side on the both equations, so the second thing you do is add x to both sides on the top equation

y=-x+3

+x +x

y+x=3

Now you times one of them by -1 so a variable will cancle out.

y+x=3

x+y=2

*-1

y+x=3

-x-y=-2

Since all the variables cancel out, there is no solution

Solve for the area (triangle)

Answers

The entire area bounded by any triangle's three sides is referred to as the triangle's area.

What is the Area of a Triangle?

In essence, it is equivalent to 1/2 of base times height, or A = 1/2 b times h. A triangular polygon's base (b) and height (h) must be known in order to calculate its area.

Whether a triangle is scalene, isosceles, or equilateral, it can be used to solve any kind of triangle.

Be aware that the triangle's base and height are at right angles to one another. In square units, the area unit is measured (m2, cm2).

Example :

Consider this triangle with a base of 3 cm and a height of 4 cm. What is its area?

Employing the formula,

Triangle's area is equal to half of b times h.

= 1/2 × 4 (cm) × 3 (cm) (cm)

= 2 (cm) × 3 (cm) (cm)

= 6 cm2.

In addition to the method mentioned above, Heron's formula can be used to determine a triangle's area when we know the lengths of its three sides.

In addition, when two sides of a triangle are known as well as the angle that forms between them, the area can be calculated using trigonometric functions. For each of these circumstances, we shall calculate the area.

fifty two cards are randomly distributed to 4 players with each player getting 13 cards what is the probability that each of them will have an ace

Answers

The probability that each of the players will have an Ace is 0.1055. The result is obtained by dividing the ways to place Aces for each player by the total ways.

How to calculate the probability on cards?

The four suits for a standard deck of 52 cards are hearts, diamonds, clubs, and spades of 13 cards each. The hearts and diamonds are red. While, the clubs and spades are black. The 13 cards are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King.

The 52 cards are randomly distributed to 4 players. So, each players will get 13 cards.

Find the probability that each of them will have an Ace!

When we distribute 13 first cards, the rest cards are 39. After 13 second cards, the rest are 26 cards, an so on. Without discerning the suits, the ways to place Aces so that each player will get an Ace is

n(A) = 13⁴

There are 4 Aces in 53 cards. The total ways to place the Aces is

[tex]n(S) = \binom{52}{4}[/tex]

The probability that each player will have an Ace would be

[tex]P = \frac{n(A)}{n(S)} = \frac{13^{4} }{ \binom{52}{4}} = \frac{28561}{270725} \approx 0.1055[/tex]

Hence, the probability that each player will get an Ace is 0.1055.

Answers

The bird flies at an angle of 60° degrees from the water, and its height from the ground when it drops the fish is 86.6 yards.

The bird caught the fish at point, flew to which is 100 yds away, and dropped the fish at C, which is horizontally 50 yards from A.

Now,
let the angle be x,
cosx = 50 / 100
x = cos⁻¹(1/2)
x = 60°

height of the bird is given as,
sin60 = height / 100
√3 / 2 = height / 100
height = 50√3 = 86.6

Thus, the bird flies at an angle of 60 °degrees from the water, and its height from the ground when it drops the fish is 86.6 yards.

Find the zeros of the function f(x) = 2x² + 20x + 46. Round values to the
nearest hundredth (if necessary).

Answers

Answer:

-6.50

Step-by-step explanation:

The zeros of the function are the x-values that make f(x) equal to zero. To find the zeros of this quadratic function, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 20, and c = 46. Plugging in the values:

x = (-20 ± √(20² - 4 * 2 * 46)) / 2 * 2

x = (-20 ± √(400 - 184)) / 4

x = (-20 ± √216) / 4

x = (-20 ± √6 * √6) / 4

x = (-20 ± 6) / 4

So the zeros are x = (-20 + 6) / 4 = (-14) / 4 = -3.5 and x = (-20 - 6) / 4 = -26 / 4 = -6.5.

Rounding to the nearest hundredth, the zeros are approximately -3.50 and -6.50.

Scenario #1 There are 3 identical rugs available for purchase at 3 different stores. The original prices of the rugs are as follows:

Store #2: $265

Store #3: $310


The rug at store #1 is on sale for 20% off. The rug at store #2 has an advertised price in this weeks catalog that is a 12% decrease from the original price. Both rugs at store #1 and store #2 have an 8% tax attached, after the discounts are applied. Store #3 is online and does not have sales tax. The original price of the rug is a 30% increase from the now advertised sales price. There is a $5. 99 shipping and handling fee. Which store has the best deal?

Answers

According to the unitary method, the store that has the best deal is Store 1 and it cost $202.18

The term unitary method is known as a process of finding the value of a single unit, and based on this value.

Here we have the original prices of the rugs are as follows:

Store #1: $289

Store #2: $265

Store #3: $310

And the discount on each store is written as,

Store #1: 20% (decrease)

Store #2: 12%(decrease)

Store #3: 30%(increase)

And the tax details are given as,

Store #1: 8%

Store #2: 8%

Store #3: no tax.

Then the shipping and the handling charges is $5.9

Then the price for each of the store is calculated as,

=> Store 1 = 289 - [(289 x 0.20) + (289 x 0.08) + 5.9] = 202.18

=> Store 2 = 265 - [(265 x 0.12) + (265 x 0.08) + 5.9] = 206.1

=> Store 3 = 310 + (310 x 0.30) - 5.9 = 397.1

Therefore, the store 1 provides the best deal on the rug.

evaluate y=1/4(4)^x for x=3/2

Answers

Answer:

When  x =  -16, y = -1.

Step-by-step explanation:

Let's plug in y = -1 into this equation

-1 = 1/4x + 3

Now, we need to solve the equation for x. To do so, we want x to be by itself on one side of the equation. We will use inverse operations to get the x by itself. First, subtract 3 from either side to under the +3 on the right side of the equation.

-1 - 3 = 1/4x + 3 - 3

-4 = 1/4x

Next, we will divide by 1/4 to undo the *1/4. Dividing by 1/4 is the same as multiplying by 4, so we will multiply each side by 4.

-4 * 4 = 1/4x * 4

-16 = x

Ana’s younger brother and sister went on a carnival ride that has two separate circular tracks. Ana’s brother rode in a blue car that travels a total distance of 220 feet around the track. Ana’s sister rode in a green car that travels a total distance of 126 feet around the track. Ana drew a sketch of the ride.


2. What is the radius of the circle made by Ana’s brother in the blue car? Use 3. 14 for pi and round your answer to the nearest tenth

Answers

A circle's circumference as a form of "perimeter."

The radius is RB = 35.0 ft, rounded to the nearest tenth (or 35 feet).

By rounding to the nearest tenth, we may determine the radius to be RG = 20.1 feet.

1.The circumferences of the two circles are 220 feet and 126 feet, respectively. We may think of a circle's circumference as a form of "perimeter."

2. The following is the radius of the circle made by Ana's brother in the blue car:

We know that the following formula determines a circle's circumference:

[tex]C=2\Pi \ r[/tex]

Then, we must get r by solving this equation. We know that C is 220 feet and pi is 3.14. Next, we have

[tex]220=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{220}{2 \pi} \\\Rightarrow r=\frac{220}{2 \cdot 3.14} \\\Rightarrow r=35.0318[/tex]

The radius, rounded to the closest tenth, is RB = 35.0 feet (or 35 feet).

3. Using the same method, we can determine the radius of the circle that Ana's sister drew in the green automobile (she travelled 126 feet).

[tex]126=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{126}{2 \cdot 3.14} \\\Rightarrow r=20.0637[/tex]

We may calculate the radius as RG = 20.1 feet by rounding to the closest tenth.

What is percentage ?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

According to question;

We have,

Total car owner = 2600

People who said to buy car again = 1300

Now

Percentage of satisfied people = [tex]\frac{1300}{2600}[/tex] × 100

Percentage of satisfied people = 50 %
