Answer: It is shopping around for the best prices and saves money.

Step-by-step explanation: Bargain has the word "gain" in it. That's the best way I would look at it. Therefor I would cross out any other option that has to do with no benefit or the loss of something. Because we you bargain, you're getting multiple of something for a good price or maybe getting something that's on sale for a good price. For example: Buy 1 get 1 free items.

Answer:

∠PQR=30°

Step-by-step explanation:

I assuming that the measure of angle PQR is the third internal angle of the triangle

Remember that

The sum of the internal angles of a triangle must be equal to 180 degrees

80°+70°+∠PQR=180°

150°+∠PQR=180°

∠PQR=180°-150°

∠PQR=30°

Answer:

The answer is 30 degrees

Step-by-step explanation:

(80+70) - 180 = 30

because all the angles should add up to 180 degrees so to double check your answer you do 30+70+80=180

By applying a change of variables to the ellipse equation x2+6xy+10y2≤1, this simplifies to the standard ellipse equation from which the area, π*sqrt(10), can be determined using the standard formula for the area of an ellipse.

To find the area of the ellipse defined by the equation x2+6xy+10y2≤1, we can begin by using the provided change of variables, s = x + 3y and t = y. This transformation simplifies the equation of the ellipse to: (s^2) / 10 + (t^2) ≤ 1.

Now the expression looks like the standard equation of an ellipse, where 'a' (the radius on the x-axis) is sqrt(10) and 'b' (the radius on the y-axis) is 1. The area 'A' of an ellipse is given by 'A=πab'. Substituting 'a' and 'b' into the formula gives us 'A = π*sqrt(10)*1 = π*sqrt(10)'

This indicates that the area of the ellipse with the change of variables s=x+3y, t=y for the equation x2+6xy+10y2≤1 is π*sqrt(10).

The  probability that the chosen animal feeds on seeds or insects or both is:

                [tex]\dfrac{3}{4}[/tex]

Let A denote the event that the animal feed on seeds.

B denote the event that the animal feed on insects

and A∩B denote the event that the animal feed on both seed and insects.

and A∪B denote the event that the animal feeds on seeds or insects or both.

Let P denote the probability of an event.

Now, based on the information from the question we have:

[tex]P(A)=\dfrac{18}{36}\\\\P(B)=\dfrac{15}{36}\\\\P(A\bigcap B)=\dfrac{6}{36}[/tex]

Now, we know that:

Answer:

a) h(x)

b) q(x)

c) w(x)

Step-by-step explanation:

Finding the answers for this is easy.  Take two values for x that shows a different Y-value for each function on the graph and place them in the equations suggested to see which equation match their Y-value on the graph.

Let's take x = -1 and x = 1.

a) h(x) = | -x + 3 |

| - (-1) + 3| = | 4 | = 4

| - 1 + 3 | = | 2 | = 2

h(x) passes through (-1,4) and (1,2)

b)  q(x) = | x | + 3

|-1| + 3 = 4

| 1 | + 3 = 4

q(x) passes through (-1,4) and (1,4)

c) w(x)  = | x+ 3 |

| -1 + 3 | = | 2 | = 2

| 1 + 3 | = | 4 | = 4

w(x) passes through (-1,2) and (1,4)

Answer:

15 yards

Step-by-step explanation:

1 balloon = 2.5 feet

18 balloons = 2.5 x 18 = 45 feet

1 yard = 3 feet

[tex]\frac{3 feet}{1 yard}=\frac{45 feet}{x yard}[/tex]

45 = 3x

x = 15 yards

For this case it is observed that the border of the region is not dotted, then the inequality includes an equal.

Thus, we discard options C and D.

We substitute the point (0,0) and see if it is fulfilled:

[tex]y\geq\frac {3} {2} x-3\\0 \geq\frac {3} {2} (0) -3\\0 \geq0-3\\0 \geq-3[/tex]

It is fulfilled, so the correct option is A.

Answer:

Option A

Answer:

A. [tex]y\geq \frac{3}{2} x-3[/tex]

Step-by-step explanation:

We are given a graph and we are to determine which inequality is described by the graph.

Since the graph has a solid line that means that the inequality includes the points on the line and must contain an equal sign.

So we will substitute the point (0, 0) to find the correct inequality.

[tex]y\geq \frac{3}{2} x-3[/tex]

[tex]0\geq \frac{3}{2} (0)-3[/tex]

[tex]0\geq 3[/tex] - true

[tex]y\leq \frac{3}{2} x-3[/tex]

[tex]0\leq \frac{3}{2} (0)-3[/tex]

[tex]0\leq 3[/tex] - false

Therefore, the correct inequality is [tex]y\geq \frac{3}{2} x-3[/tex].

Answer:

the answer is he rode 17 miles in the morning and 40 miles in the afternoon

Step-by-step explanation:

so in the afternoon, it says that 6 more than twice as many miles in the afternoon as in the morning. this means that if the morning is x then in the afternoon it will be 2x+6 but it says altogether it is 57 miles so the you have to add x too.

so the equation is 2x+6+x=57

then this should be easy to solve.

2x+6+x=57

3x+6=57

3x=51

x=17

so if the morning is 17 miles then the afternoon will be:

2(17)+6

this equals to 40.

Answer:

It is A.

Step-by-step explanation:

In function A we see that there are 2 ordered pairs with value 2 in the first position with y values 6 and 2. So this is not a function.

A function is a relation in which each input pairs with exactly one output. In the given relations, option A is not a function because the input 2 pairs with both 6 and 2, contradicting the definition of a function.

In mathematics, a function is a relation in which every input, also known as the domain, corresponds to exactly one output, called the range. Looking at the following relations, we determine if a relation is not a function by seeing if any input values are paired with more than one output.

Option A: {(2, 6), (- 4, 0), (2, 2), (3, 5)} is NOT a function because the input 2 corresponds to both 6 and 2, which violates the definition of a function.

Options B, C, and D each pair every input with exactly one output, thus they are all functions. In conclusion, the relation provided in option A is the only one that is not a function.

Answer:

tan(Sin^-1 x/2)=  [tex]\frac{x/2}{\sqrt{1-x^{2}/4 } }[/tex]

Step-by-step explanation:

Let sin^-1 x/2= θ

then sinθ= x/2

on the basis of unit circle, we have a triangle with hypotenuse of length 1,   one side of length x/2 and opposite angle of θ.

          tan(Sin^-1 x/2) = tanθ

           tanθ= sinθ/cosθ

as per trigonometric identities cosθ= √(1-sin^2θ)

           tanθ= sinθ/ √(1-sin^2θ)

substituting the value sinθ=x/2 in the above equation

             tanθ= [tex]\frac{x/2}{\sqrt{1-x^{2}/4 } }[/tex]

now substituting the value sin^-1 x/2= θ in above equation

             tan(sin^-1 x/2) =  [tex]\frac{x/2}{\sqrt{1-x^{2}/4 } }[/tex]

The probability that the die will land with a value less than 3 and on a red square, given an equal number of black and red squares, is 1/6.

The subject of this question is probability, a branch of Mathematics. In the given scenario, Gabrielle is tossing a die onto a black-and-red checkerboard. There are two separate events here - the roll of the die and the colour of the square where the die lands.

Firstly, the probability that the die will land with a value less than 3 is 2/6, or 1/3, as there are two sides of a six-sided die that have values less than 3 (1 and 2).

Secondly, assuming the checkerboard has an equal number of red and black squares, the probability that the die will land on a red square is 1/2.

Since these are separate events, we can calculate the combined probability by multiplying the probabilities of the individual events: (1/3) * (1/2) = 1/6. So, the answer is 1/6.

Answer:

according to the equation it is 158.330917...

Step-by-step explanation:

put w as 64 and solve for t

Answer: 158.331 minutes.

Step-by-step explanation: To solve this problem we need to replace the given level of water (64 cups) in the equation, and isolate and calculate the time (t):

W=-0.414t+129.549

isolating t:

W-129.549=-0.414t

t=(W-129.549)/-0.414

replacing W=64

t=(64-129.549)/-0.414

t=-65.549/-0.414

t=158.331 minutes.

The answer is -- 29,524

Answer:

29,524

Step-by-step explanation:

This is a geometric sequence; notice how each new term is 3 times the previous term.  Thus, a(n) = 1 · 3^(n-1).  The 10th term is a(10) = 3^(9) = 19683.

a(4) = 27 (given)

a(5) = 81 (calculated)

a(6) = 243

a(7) = 729

a(8) = 2107

a(9) = 6561

a(10) = 19683 (previously calculated)

So the sum of the first 10 terms is 29,524.

1 + 3 + 9 + 27 + 81 + ... + 6561 + 19683 =

the answer is

10 × (4+3) = 70
