Answer:

7.5

Step-by-step explanation:

Answer:

first is 3.5, second is 1

Step-by-step explanation:

-4.5 = x + 2x - 6

-4.5 - 6 = 3x

10.5 = 3x

10.5/3 = x

3.5 = x

2(3.5) - 6

There will be a total of 5040 unique ways to make arrangements of 4 cards out of 10 so option (A) will be correct.

When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.

The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.

Given the 4 cards arrangement out of 10

npr = n! /(n-r)!

Here n = 10 , r = 4

10p4 = 10! /(10-4)!

10p4 = 10 × 9 × 8 × 7 × 6! /6!

10p4 = 5040

So there will be a total of 5040 ways to arrange the cards.

Answer:

m<K = 63

Step-by-step explanation:

Exterior angle thm:

6x - 9 + 4x + 7 = 118

10x - 2 = 118

10x = 118 + 2

10x = 120

x = 12

Answer:

w = 21

Step-by-step explanation:

Given that,

                      game 1                     game 2

Points               12                            18

Shots                 14                            w

One proportion is : [tex]\dfrac{12}{14}=\dfrac{6}{7}[/tex]

Other proportion is : [tex]\dfrac{18}{w}[/tex]

So,

[tex]\dfrac{6}{7}=\dfrac{18}{w}\\\\w=\dfrac{7\times 18}{6}\\\\w=21[/tex]

So, the value of w is equal to 21.

Answer:

245.5 cm²

Step-by-step explanation:

Formula : -

Area of square = side²

Area of square

= 18²

= 324 cm²

Formula : -

Area of circle = πr²

Area of circle

= ( 22 / 7 ) x 5 x 5

= 3.14 x 25

= 78.5 cm²

Area of shaded region

= ( Area of square ) - ( Area of circle )

= 324 - 78.5

= 245.5 cm²

Step-by-step explanation:

To find how many degrees the temperature would have to rise you need to do 11 - (-7) which is equal to 18. So the temperature rose 18 degrees.

To convert Celsius to Fahrenheit you need to do

(C * 9/5) + 32. In this case it would be (11 * 9/5) + 32 which results in 51.8 degrees Fahrenheit.

Answer:

A

Step-by-step explanation:

3 + (-7) + 2/5 + (-1/5)

Answer:

I'm guessing you meant 3/13 of 18.

In that case, the answer would be 4.2 rounded to the nearest tenth (the actual answer is 4.15384615)

Answer:

962.5 ft²

Step-by-step explanation:

Area of landing pad = Area of circle

d = 35 ft, r = 35/2 ft

Area = [tex]\pi r^2[/tex]

[tex]\pi r^2[/tex] = [tex]\frac{22}{7} * \frac{35}{2}* \frac{35}{2}[/tex]

     = 962.5 ft²

Thus area of landing pad = 962.5 ft²

Answer: <B= 101, <C= 79, <D=101

Step-by-step explanation: all parallelograms have the diagonal angles equal so that is why <c=79. Parallelograms also have all angles equal to 360. so if you add <C, and <A you have 158. then you subtract that from 360 and you get 202. You then need to divide it by to to get the measures of angles B and D which are 101 each.

Answer:

(6, 6)

Step-by-step explanation:

Answer:

The distance is 8.4853

Step-by-step explanation:

Input Data :

Point 1 (xA, yA) = (0, -1)

Point 2 (xB, yB) = (6, 5)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB − xA) ^ 2 + (yB − yA) ^ 2

Solution :

Distance between two points = √ (6 − 0)^2 + (5− −1) ^ 2

= √6^2 + 6^2

= √36 + 36

= √72

= 8.4853

Distance between points (0, -1) and (6, 5) is 8.4853

hope this helps and is right :)

Answer:

  B  reflected over y, translated up

Step-by-step explanation:

The left-right reversal means there was a reflection over a vertical line. The only one among the offered choices is the y-axis.

If the lines are reflected over the y-axis, the points on the y-axis don't move. The intercepts would still be 2 and 5 after the reflection.

However, the y-intercepts have moved up 3 units to 5 and 8.

  Lines g and h were reflected over the y-axis and translated up 3 units.
