Which point could represent 5/3?
B -3
A -1/2
D 1/2
C 1 1/2
​

Answer:

x=6

Step-by-step explanation:

-5(x - 2) = -20

first multiple 5 by x and -2

-5x 10 = -20

subtract 10 from 10 and -20

-5x=-30

then divide 5

x=6

Answer:

-90=[tex]x[/tex]([tex]x[/tex]-18)

-90=[tex]x^{2}[/tex]-18[tex]x[/tex]

[tex]0=x^{2}-18x+90[/tex]

[tex]x=9+3i or 9-3i[/tex]

Step-by-step explanation:

you need to use quadratic formula and you will find square root a negative ( -9 ), which is an imaginary no.

square root (-9) = 3i

Given:

Length of a cube is 2 cm

To Find:

Surface area of the cube

Solution:

A cube consists of 6 faces.

The area of each face = side x side

So, the total surface area of a cube = 6 x

side x side

Let a be the length of the given cube

: Surface area of a cube = 6a square

a = 2 cm (Given)

Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.

Hence, the surface area of the given

cube is 24cm square.

Step-by-step explanation:

xy = k, where k is a real constant.

When x = 2, y = 60.

=> (2)(60) = k, k = 120.

Hence when y = 24, x(24) = (120), x = 5.

Answer:

1600-400pi

Step-by-step explanation:

There are 2 semicircles making it a full circle. We are doing (40*40)-the area of the circle. We do 20*20 since that it is the radius and get 400. We then multiply it by pi. We get 400pi. Now we find the area of the square. This is 40*40 which gives us 1600. 1600-400pi is our answer

Velocity is a vector, so it has a magnitude and direction.

Speed is its magnitude, which is obtained from

|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s

Its direction is an angle θ made with the positive horizontal axis, satisfying

tan(θ) = (4 m/s) / (-3 m/s) = -4/3   →   θ = arctan(-4/3) + 180°n

where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about

θ ≈ 126.87°

Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that

〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)

(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)

-3/5 = cos(θ)   →   θ = arccos(-3/5) + 360°n

where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

Answer:

27.5

Step-by-step explanation:

Answer: I got 27.5

Step-by-step explanation:

This is a fraction equal to

220 miles ÷ 8 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 8

220 miles ÷ 8

8 hours ÷ 8

=

27.5 miles

1 hour

=

27.5 miles

hour

= 27.5 miles per hour

Step-by-step explanation:

The difference between the new, colder temperature and the original temperature is 30 ° C.

"Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume."

Given,

The old temperature is = 18°C

The new temperature is = -12°C

The difference in temperature is [tex](-12\°C - 18\°C) = 30\°C[/tex]

Hence, A is the correct option.

Given:

Rate of sales tax = 7%

Marked price of an item = $19.94

To find:

The final cost of the item once tax is included.

Solution:

We have,

Rate of sales tax = 7%

Marked price of an item = $19.94

[tex]\text{Sales tax}=\dfrac{7}{100}\times 19.94[/tex]

[tex]\text{Sales tax}=1.3958[/tex]

Now, final cost of the item once tax is included is

[tex]\text{Final cost}=\text{Marked price}+\text{Sales tax}[/tex]

[tex]\text{Final cost}=19.94+1.3958[/tex]

[tex]\text{Final cost}=21.3358[/tex]

Therefore, the final cost of the item once tax is included is $21.3358.

Answer:

Costo  unitario= $3

Step-by-step explanation:

Dada la siguiente información:

Entrada= $4.5

Cantidad de entradas de más= 2

Cantidad de amigos que pagan= 3

Primero debemos calcular el total a pagas de más:

Total a pagar de más= 2*4.5= $9

Ahora, cuánto debe pagar cada uno:

Costo unitario= costo total / cantidad de personas

Costo unitario= 9/3

Costo  unitario= $3

Answer:

The value of the correlation coefficient would not change.

Step-by-step explanation:

If the relationship between distance of trips and fares in dollars gives a correlation coefficient value of 0.950. This can be interpreted to mean that the relationship between both variables is strong and positive such that an increase in distance leads to corresponding increase in fares of the trip and vice versa. Thus, interchanging the axis upon which the variables are plotted would still tied the same correlation Coefficient value as the correlation coefficient does not depend on the axis upon which the variables are plotted.

Step-by-step explanation:

If its change it will not be right

Step-by-step explanation:

Given the expression

2m/2m+3 - 2m/2m-3 = 1

Find the LCM of the expression at the left hand side:

2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m²  - 9

-12m = 4m²  - 9

4m²  - 9+12m = 0

4m² +12m-9 = 0

Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2

The number of yards in 1 foot is 3 thus 20 packages can be wrapped.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

As per the given,

Length of ribbon = 20 yards

Each package required = 3 feet

Since 1 yard = 3 feet so,

Each package required = 1 yard

The number of packages that can be wrapped = 20/1 = 20

Hence" The number of yards in 1 foot is 3 thus 20 packages can be wrapped".
