Answer:

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30

Step-by-step explanation:

These are independent events.

The probability of rolling a 5 is 1/6.

The probability of spinning a 5 is 1/5.

The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.

There are 30 outcomes. Roll first then spin to get the following outcomes:

11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65

You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.

(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.

Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.

Answer:

16.7%

Step-by-step explanation:

There are 6 sides and one three on the cube so rolling a three would be 1/6. To roll a 6 on a 6 sized dice would be the same there’s 6 sides and one 6 so it would be 1/6

Tip: $13.14

Total cost: $86.14

Step-by-step explanation:

Bill: $73.00

18% of 73: 1% of 73 = 0.73

0.73 x 18 = 13.14

Tip: $13.14

Total cost:

73.00 + 13.14 = $86.14

Answer:88= 6x+40

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The formula for the area of a rectangle is L x W, so we just sub in the formula.

L × W = Area

8 × (¾x + 5) = 88

This is the same as 8¾x + 5 = 88.

Answer:

Options (B) and (E)

Step-by-step explanation:

Area of ΔABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                        = [tex]\frac{1}{2}(14)(6)[/tex]

                        = 42 in²

Area of trapezoid ADEC = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

[Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and 'h' is the height of the isosceles trapezoid given]

= [tex]\frac{1}{2}(10+14)(8)[/tex]

= 96 in²

Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC

                                    = 42 + 96

                                    = 138 in²

Therefore, Options (B) and (E) are the correct options.

y = -1.5 + 3x

Step-by-step explanation

I'm sorry but I have no time, can someone comment me and explain? Thank you :)

Answer: y = -1.4(2.1 - 4.2x)

Step-by-step explanation:

4.2x - 1.4y = 2.1

Firstly you should move 4.2x over (by subtraction) so the new equation is:

-1.4y = 2.1 - 4.2x

Then you want to multiply everything by -1.4 to take it away from the y side. This will bring you to:

y = -1.4(2.1 - 4.2x)

This can be simplified down to

y = -2.94 + 5.88x

or

5.88x -2.94 = y

Answer:

Answer:

5

Step-by-step explanation:

5 × 5 × 5= 125 so 5 is the cube root

Answer:

Step-by-step explanation:

I have this information memorized. The cube root of 125 is simply 5, because 5 x 5 x 5 = 125.

So your answer is 5.

Answer:

x = 20

y = 10

m∡8 = 110°

Step-by-step explanation:

m∡1 + m∡2 = 180

5x + y + 3x + y = 180

8x + 2y = 180

m∡1 = m∡8    (they are alternate-exterior angles and are congruent)

5x + y = 3x + 5y

2x = 4y

x = 2y

Substitute '2y' for 'x' in 8x + 2y = 180

8(2y) + 2y = 180

18y = 180

y = 10

x = 2(10)

x = 20

m∡8 = 3(20) + 5(10) = 110°

Answer:

24

Step-by-step explanation:

Four total places someone can come - 1st, 2nd, 3rd or 4th. Anyone can come 1st - 4 people

Now only the remaining 3 can come second - 3 people

Next, only the remaining 2 people can come third - 2 people

Finally, one person comes last - 1 person

4 x 3 x 2 x 1 = 24

Answer:

a = 3

Step-by-step explanation:

Factorize (x+5)(x-4)(x+2)

(x+5)(x-4)(x+2)

=  (x²-4x+5x-20)(x+2)

= (x²+x-20)(x+2)

= (x³+2x²+x²+2x-20x-40)

= x³+3x²-18x -40

Compare with x^3+ax^2

3x² = ax²

3 = a

Rearrange

a = 3

Hence the value of a that makes the expressions identical is 3

Answer:

4.7, 5.1 and 7.4

Step-by-step explanation:

Given

[tex]t \le 7.4[/tex]

Required

Select numbers part of the solution

O  4.7    O 5.1      O 7.4      O 8.2     O 9.6​

[tex]t \le 7.4[/tex] implies that, the value of t cannot exceed 7.4.

So, we have:

4.7, 5.1 and 7.4 in this range

However, 8,2 and 9,6 do not belong to this range

x = 0

y = -15

Step-by-step explanation:

1/2x-1/3y = 5

x = 2/3y+10

substitute x

1/2(2/3y+10)-1/3y = 5

1/3y+5-1/3y = 5

5 = 5

x = 0

-1/3y = 5

-1/3y/-1/3 = 5/-1/3

y = -15

9 - 0 = 9

13 - 4 = 9

the ten becomes a 9 because you borrow 1

9 - 3 = 6

13 - 7 = 6

you borrowed from the 4 before, so it is 13, not 14

since you borrowed from the 7, it becomes a 6 now.

Answer:

up 2, right 3

Step-by-step explanation:

up 2, to the right 3.

The translation was 2 units right and 3 units up.

As per the given data:

We are given AB with the coordinates as, A(-3, -1) and B(2, 1).

After translation, AB becomes A'B' with A'(-1, 2) and B'(4, 4).

We can find out the translation by finding out the change in the corresponding coordinates.

For A to A':

Change in x coordinate = -1 - (-3) = -1 + 3 = 2

Change in y coordinate = 2 - (-1) = 2 + 1 = 3

Increase in x coordinate of 2 units = 2 units right.

Increase in y coordinate of 3 units = 3 units up

Hence, the translation was 2 units right and 3 units up.

Answer:

a=180-79

a=101

c=83 (vertically opposite angles)

d=c (corresponding angles)

d=83

b=a(corresponding angles)

b=101

Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.
