There is none of these numbers are divisible by 9 and the required number is 474 divisible by 3 which the correct answer would be an option (D)

The divisibility rule states that " Divisible By, implies that when two numbers are divided, the result would be a whole number.

The sum of the digits should be divisible by 9

⇒ 474 : (4+7+4=15, and again, 1+5=6)

This number is not divisible by 9

⇒ 127  : (1+2+7=10, and again, 1+0=1)

This number is also not divisible by 9

⇒ 907  : (9+0+7=16, and again, 1+6=7)

This number is also not divisible by 9

The sum of the digits should be divisible by 3

⇒ 474 : (4+7+4=15, and 15÷3 = 5)

This number is divisible by 3

⇒ 127  : (1+2+7=10, and 10÷3 = 3.333)

This number is not divisible by 3

⇒ 907  : (9+0+7=16, and  16÷3 = 5.333)

This number is not divisible by 3

Answer:

  $433

Step-by-step explanation:

You want the average cost per student for an enrollment of 350 students as interpolated from a table of enrollments and costs.

There are a number of ways the cost table might be interpolated. The one used here is to use quadratic regression to write a formula for the cost as a function of enrollment. Then the function value for 350 students is found. This is all accomplished using a graphing calculator, as shown in the attachment. The interpolated value for an enrollment of 350 students is $433 per student.

Another method of interpolation could use linear interpolation between the two nearest points. Our enrollment of interest, 350, is halfway between 250 and 450, so the cost per student could be estimated to be halfway between 473 and 411:

  cost per student = (473 +411)/2 = 442 . . . dollars per student

We know this estimate is a bit high, because the cost function is concave upward. A straight line between two points on the curve will lie above the curve.

Other methods of interpolation will give other values. A cubic interpolating function gives a value of $428 per student.

The water in gallons to entirely fill the swimming pool is 51705.344 gallons.

For the given question;

The volume of the pool = 256 yd³.

Convert the volume in yd³ in gallons.

1 yd³ = 201.976 gallons.

Thus, for the total volume of 256 yd³ multiply both side with 256.

1×256 yd³ = 201.976×256 gallons.

256  yd³ = 51705.344  gallons.

A real-world situation where you can apply the unit rate is finding the cost of a single can of soda from a pack of soda.

The unit rate refers to the price of a single item out of a number or group of items. It is found by dividing the total price of the group of items by the number of items in the group.

In a real-world scenario, you might see a pack of soda priced at $5.20 and you need to know the price of a single can of soda. You can find this by the formula:

= Price of soda pack / Number of soda cans

= 5.20 / 6

The value of x and y that allows these two triangles to be congruent is

(-12, 11)

The congruence of two or more triangles is determined by the measurements of their sides and angles. The three sides of a triangle determine its size, and the three angles determine its shape.

Two triangles are said to be congruent if the pairs of their corresponding sides and angles are equal. They are the same size and shape. Triangles have numerous congruence conditions.

Here we will use translation to find out units of displacements

If the triangle is congruent then vertices are of same shape too which means coordinate of first triangle will give us coordinate of second triangle

The coordinates of 1st vertices of traingle1 = (5, 4), x = 5, y = 4

The coordinates of 1st vertices of traingle2 = (1, 6), x = 1, y = 6

By subtracting,

translation x = 5 - 1 = 4

translation y = 4 - 6 = -2

Thus the vertices of other triangles are translated 4 units left and 2 units up. Same goes for second vertices

-4 - 4 = 8

6 + 2 = 8

And the same will go for the last vertices (-8, 9) that is

-8 - 4 = -12

9 + 2 = 11

The value of x and y that allow these two triangles to be congruent is (-12, 11)

[tex]y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]

Step-by-step explanation:

Given equation:

[tex]\pi=7x-2y[/tex]

To isolate y, add 2y to both sides:

[tex]\implies\pi+2y=7x-2y+2y[/tex]

[tex]\implies\pi+2y=7x[/tex]

Subtract π from both sides:

[tex]\implies\pi+2y - \pi=7x- \pi[/tex]

[tex]\implies 2y=7x- \pi[/tex]

Divide both sides by 2:

[tex]\implies \dfrac{2y}{2}=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]

[tex]\implies y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]

This can also be written as a rational function:

Answer:

Step-by-step explanation:

Now we have to,

→ find the required value of y.

The equation given is,

→ π = 7x - 2y

Then the required value of y will be,

→ π = 7x - 2y

→ -2y = π - 7x

→ y = (π - 7x)/(-2)

→ [ y = (-π + 7x)/2 ]

Hence, the equation is (-π + 7x)/2.

Area is the amount of space a 2-D shape occupies.

Area Formula

As stated above, the area of a triangle is [tex]\frac{1}{2}bh[/tex]. When solving for area, it doesn't actually matter which side is the base. You just have to remember to take the height perpendicular to the base you use. Since this is a right triangle, the height is the same as one of the legs. For the purpose of this question, I will use 12 as the base and 15 as the height. Because the 12 and 15 sides are perpendicular to each other, we can plug them into the formula for b and h.

Solving For A

Now we can just plug 12 and 15 in and solve.

The area of the triangle is 90 in².

The next three terms in the geometric sequence will be 24, 48 and 96.

We are given a geometric sequence:

3, 6, 12 …

We need to find the next 3 terms of the sequence.

We can see that:

a = initial term of the sequence

a = 3

r = common ratio between the consecutive terms.

r = 6 / 3 = 2

Now, nth term will be represented by:

aₙ = a rⁿ⁻¹

Substituting the values of a and r in the formula, we get that:

aₙ = 3 (2)ⁿ⁻¹

Now, the 4th term will be ( put n = 4)

a₄ = (3) (2)⁴⁻¹

a₄ = (3) (2)³

a₄ = (3) × (8)

a₄ = 24

The 5th term will be: (put n = 5)

a₅ = (3) (2)⁵⁻¹

a₅ = (3) (2)⁴

a₅ = (3) × (16)

a₅ = 48

6th term will be: (put n = 6)

a₆ = (3) (2)⁶⁻¹

a₆ = (3) (2)⁵

a₆ = (3) × (32)

a₆ = 96

Therefore, the next three terms in the geometric sequence will be 24, 48 and 96.

Answer: x=26 degrees

Step-by-step explanation:

90+x+64=180 ==> A right angle, x, and 64 lie on a straight line. Straight lines add up to 180 degrees and are called straight angles. Right angles are denoted with a tiny square inside them and measure 90 degrees.

90-90+x+64=180-90

x+64=180-90

x = 8

y = 9

If x varies in opposition to y, then

x*y = fixed

The point (x,y,z) =  (₋1,3,₋1) is the solution of the equations.

Given the system of equations are:

2x ₊ y ₊ 3z = ₋2 .....eq(1)

x ₋ y ₋ z = ₋3 ...... eq(2)

3x ₋ 2y ₊ 3z = ₋ 12 .... eq(3)

Solving equation 1 and 2.

2x ₊ y ₊ 3z = ₋2

x ₋ y ₋ z = ₋3

Multiply eq(1) by 1 and eq(2) by 2, we get:

2x ₊ y ₊ 3z = ₋2

2x ₋ 2y ₋ 2z = ₋6

⁻     ⁺     ⁺         ⁺

hence sign changes, then we get:

3y ₊ 5z = 4 ... eq(a)

now solving equation 2 and 3.

x ₋ y ₋ z = ₋3

3x ₋ 2y ₊ 3z = ₋ 12

Multiply eq (2) by 3 and eq (3) by 1.

₋3x ₊ 3y ₊ 3z =  9

3x ₋ 2y ₊ 3z = ₋ 12

sign changes, and we get:

y ₊ 6z = ₋3 ..... eq(b)

y = ₋3 ₋ 6z

substitute y value in eq(a)

3(₋3₋6z) ₊ 5z = 4

₋9 ₋ 18z ₊ 5z = 4

₋13z = 13

z = ₋1

substitute z value in eq(b)

y ₊ 6(₋1) = ₋3

y ₋ 6 = ₋3

y = 3

substitute y and z values in eq (2)

x ₋ (3) ₋ (₋1) = ₋3

x ₋ 3 ₊ 1 = ₋3

x ₋ 2 = ₋3

x = ₋3 ₊ 2

x = ₋1
