find the width and height of an newer 90 inch televison whose aspect ratio is 16:9

The constant of variation is 72.

In a direct variation, the constant of variation is the constant (unchanged) ratio of the two variables. The formula for direct variation is. where k is the variational constant and y=kx (or y=kx).

being that

x = 8

y = 9

If x varies in opposition to y, then

x*y = fixed

which means

x*y = k (where we assume constant as k) (where we take constant as k)

Inputting the values of x and y now yields,

8*9 = k

72 = k

Consequently, 72 is the constant of variation.

The triangle was translated 5 units down and then reflected over the x axis to get (-1, 2), (2, 6) and (-5, 8)

Transformation is the movement of a point from its initial location to a new location. Types of transformations are reflection, rotation, translation and dilation.

Transformation is the movement of a point either up, down, left or right in the coordinate plane.

The triangle shown has vertices at (-1, 3), (2, -1) and (-5, -3). It was translated 5 units down to get (-1, -2), (2, -6) and (-5, -8). It is then reflected over the x axis to get (-1, 2), (2, 6) and (-5, 8)

Answer:

  2 7/8 yards

Step-by-step explanation:

Given 6 1/8 yards of ribbon, you want the leftover amount after making 4 bows that use 13/16 yards each.

If each of 4 bows takes 13/16 yards, the amount required for bows is ...

  4×13/16 = 13/4 . . . . yards

The amount left over is the difference between the starting amount and the amount used:

  6 1/8 - 13/4 = 49/8 -26/8 = 23/8 = 2 7/8

The hairdresser has 2 7/8 yards of ribbon remaining.

Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.

Let's define the variables:

We know that Ken invested $10,000 in total, so:

x + y = 10,000

And the interest in one year is:

x*0.04 + y*0.06 = 514

Then we have a system of equations:

x + y = 10,000

x*0.04 + y*0.06 = 514

To solve it we start by isolating one of the variables in one of the equations, isolating x we will get:

x = 10,000 - y

Replacing that in the other equation we get:

(10,000 - y)*0.04 + y*0.06 = 514

400 - y*0.04 + y*0.06 = 514

400 + y*0.02 = 514

y = (514 - 400)/0.02 = 5,700

Then Ken invested $5,700 in the 6% account, and the other $4,300 in the 4% account.

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+64=90

x+64-64=90-64

From the information, it was stated that the ratio of orange to apples is 2:3.

In this case, let the number of apples be represented by x

Therefore, the number of will be:

2/3 = 10/x

Cross multiply

2x = 10 × 3

2x = 30

Divide

x = 30 / 2

x = 15

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 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

Therefore the solution to the system of equations is: (₋1,3,₋1)

Step-by-step explanation:

Divide: 5 : 1/5 = 5/1 · 5/1 = 5 · 5/1 · 1 = 25/1 = 25 Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1/5 is 5/1) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.In other words - five divided by one fifth is twenty-five.

The graph which does not represent y as a function of x is (B) as a line drawn can't touch the graph at two points.

The function that dose not show y as a function of x.

Y is a function of X, means that a certain variable magnitude or phenomenon Y is determined/caused by another magnitude or phenomenon X, such that the behavior of X will affect that of Y. In logic, a function symbol is a logical symbol that may be applied to an object term to produce another object term.

If a vertical line is drawn such that it touches more than one place, then it is not a function of x.

Here also if a vertical line will be drawn it will touch two places in the curve.

So, in figure B, y is not a function of x.

The function that hides y's relationship to x.

A variable's magnitude or phenomena Y is determined by or caused by a different variable's magnitude or phenomenon X, meaning that X's behavior will have an impact on Y's. A function symbol in logic is a logical symbol that can be used to transform one object term into another.

A vertical line is not a function of x if it is drawn so that it touches many locations.

4 cuboids of dimensions 15, 30, and 15 cm will be needed to form a cube

The volume of the cuboid is l×b×h where l is length, b is breath and h is the height

The volume of given cuboid  = l b h

 = 15× 30 ×15

= 6750 cm3

The volume of a cube is a3 where a is the edge of the cube

The edge of the cube can be 30cm

The volume of cube= [tex]a^{3}[/tex]

= [tex]30^{3}[/tex]

= 27000 [tex]cm^3[/tex]

To find out the number of cuboids to be required to form a cube will be the volume of the cube divided by the volume of a cuboid

No of cuboids required = (volume of the cube)/(volume of the cuboid)

= 27000/ 6750

 = 4

So, 4 cuboids of 30 ×15 ×15 are required to make a cube whose edge is 30cm
