The total cost for the number of raffle tickets is given by y = 4x; while the cost of 6 tickets is $24

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the total cost of x tickets.

From the table:

1 ticket cost $4, hence:

y = 4x

The cost of 6 tickets is:

y = 4(6) = 24

The total cost for the number of raffle tickets is given by y = 4x; while the cost of 6 tickets is $24

Answer: 8 units

Step-by-step explanation:

  We will use the distance formula.

[tex]\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}[/tex]

[tex]\displaystyle d=\sqrt{(-4-4)^2 +(7-7)^2}[/tex]

d = 8

Answer:

you are correct keep up the good work.

Answer:

The 1st one is correct and the second one is (5, -3)

Step-by-step explanation:

For the 1st question this is what I did:

d=√(x^2−x^1)^2+(y^2−y^1)^2

d=(0−4)^2+(6−3)^2

√d=(−4)^2+(3)^2

√d=16+9

√d=25

√d=5

For the second question I did this:

(xM,yM)=(x1+x2/2,y1+y2/2)

M=(xM,yM)

M=(x1+x2/2,y1+y2/2)

M=(3+7/2,−1+−5/2)

M=(10/2,−6/2)

M=(5,−3)

A circle is a curve sketched out by a point moving in a plane. The circumference of the ring of fire is 6.2831 meters.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The circumference of the ring if the radius is 1 meter is,

Circumference of the ring = 2πr = 2 × π × 1 = 6.2831 meters

Hence, the circumference of the ring of fire is 6.2831 meters.

Answer:

Agree.

Step-by-step explanation:

1. (5^r)^t can be represented simply as 5^rt.

2. when r as negative integer, t as positive integer, rt is always a negative integer

3. when ever the indices rt is negative, the number 5^rt will be less than 1, thus cannot be a whole number for sure.

Answer:

-10x + 4y = -53

Step-by-step explanation:

-5x+2y = -29

5x - 2y = 24

subtract both values from up to down

-5x - 5x = -10x

2y - (-2y) = 4y

-29 - 24 = -53

-10x + 4y = -53

Answer:

Step 1-Write an equation, letting x represent Kareem’s age:

(x + 3) + x + 2 x = 33

Step 2-Solve the equation:

(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.

Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.

Which corrects the student’s first error?

1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.

2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.

3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.

4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.

Answer: 570 total calories

Step-by-step explanation:

450 calories in 50 grams of fat

120 calories in 30 grams of protein

120 + 450= 570

The given statement can be written as:

6+√-80

To solve √-80 re-write -80 as -1 * 80

Now √-80 =√-1 * 80

Now we can write it as:

6+ √-1 * √80

We know that √-1 = i

Thus it becomes:

6+ i√80

Now find the square root of 80

80 does not have a perfect square root

Its square root can be found as 80 = 4*4*5

Then,

6+i√4*4*5

Notice that 4 makes a pair.. So we will write it outside the square root

6+1*4√5

We will write it as:

6+4i√5

Thus the correct option is 6 plus 4 i times the square root of 5....

Answer:

Let a two digit number be, 10x + y.

75% of the number is,

= 75 % of (10 x + y)

= 75/100 × (10x+y)

= 3/4 × ( 10x + y)

According to the question, When increased by 75%, The digits must be reversed.

So,

(10 x + y) + 3/4 ( 10x + y) = 10y + x

4 (10x + y) + 3 ( 10x + y) = 4 ( 10y + x)

7(10x + y) = 4(10y + x)

70x + 7y = 40y + 4x

70x - 4x = 40 y - 7y

66x = 33y

2x = y

So,

x = 1, y = 2, 10x + y = 12

x = 2, y = 4, 10x + y = 24

x = 3, y = 6, 10x + y = 36

x = 4 , y = 8 , 10x + y = 48

x can't be 5, as y will be 10 ( y should be a single digit).

Therefore, 4 two digit numbers are possible.

Step-by-step explanation:

The area of the region enclosed by the petal of a rose curve r = sin2θ in the first quadrant is π/8 square units

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

We know the area in the polar coordinates is given by:

[tex]\rm A =\int\limits^a_b {\dfrac{1}{2}r^2} \, d\theta[/tex]

We have r = sin2θ

Here the quadrant is not given, so we are assuming we need to find the area in the first quadrant.

Put this value in the above integration and limit 0 to π/2

[tex]\rm A =\int\limits^{\dfrac{\pi}{2}}_0 {\dfrac{1}{2}(sin^22\theta)} \, d\theta[/tex]

After solving the above integration, we get:

[tex]\rm A = \dfrac{\pi}{8}[/tex]

Thus, the area of the region enclosed by the petal of a rose curve r = sin2θ in the first quadrant is π/8 square units

38/3 => 12.6667 yards which would be closest to 13 yards

The formula is to divide the lenght value by 3.

The number 38 feet is equal to 12.67 yards.

We have to give that,

To change 38 feet into yards.

Since we know that,

1 yard = 3 feet

1 feet = 1/3 yards

Hence, change 38 feet into yards as,

1 feet = 1/3 yards

38 feet = 38/3 yards

The measure of the angle MOP is 61° (Third option)

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Angle MON is a straight angle → ∠MON=180°

∠QON=58° (according to the graph)

OP bisects angle ∠MOQ, then OP divides angle ∠MOQ into two equal angles:

∠MOP=∠POQ=∠MOQ/2  (1)

∠MOQ+∠QON=∠MON

Replacing the known values in the equation above:

∠MOQ+58°=180°

Solving for ∠MOQ: Subtracting 58° on both sides of the equation

∠MOQ+58°-58°=180°-58°

∠MOQ=122°

Replacing ∠MOQ by 122° in the equation (1)

(1) ∠MOP=∠POQ=122°/2

∠MOP=∠POQ=61°

The answer will be option B. The y-values are all greater than or equal to 2.

A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Here no matter what x is, y will always be positive, because the absolute value of x-5 will always be positive. The smallest value that y can be is when x is 5, because then the absolute value of x-5 is 0, and then y is 2.

Therefore, the correct answer will be option B. The y-values are all greater than or equal to 2.
