Answer:

There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.

Step-by-step explanation:

The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.

To find the probability of both of those events happening, multiply them.

(1/5) * (3/19) = 3/95.

Answer: price was $150

Step-by-step explanation: original price was x. When discount is 30%

Price is (100-30)% = 70 % from the original. 70% = 0.70

So we have an equation 0.7x = 105. And x= 105/0.7= 150

Step-by-step explanation:

Answer: No he would have 8.5$

Step-by-step explanation:

15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short

If Eric buys the jumper, he will not have £10 left to give to his sister.

To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.

Initial amount Eric has = £15

Cost of the scarf = £8.50

Amount received from his nan = £20

Cost of the jumper = £18

Amount to give to his sister = £10

First, let's calculate Eric's remaining balance after buying the scarf:

Remaining balance = Initial amount - Cost of the scarf

Remaining balance = £15 - £8.50

Remaining balance = £6.50

Next, let's calculate Eric's balance after receiving money from his nan:

Total balance = Remaining balance + Amount received from nan

Total balance = £6.50 + £20

Total balance = £26.50

Now, let's check if Eric can still afford to buy the jumper:

If Eric buys the jumper:

New balance = Total balance - Cost of the jumper

New balance = £26.50 - £18

New balance = £8.50

The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.

Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.

Step-by-step explanation:

Answer:

(-4, 0.5)

Step-by-step explanation:

Answer:

(1) commutative property of the addition.

(2) distributive property of the multiplication and associative property of the addition.

(3) addition property of the equality.

(4) multiplication property of the equality.

Step-by-step explanation:

First we start with:

4x + 1 + x + 3 = -11

Here we use the commutative property of the sum, which says that:

A + B = B + A

So we can reorder the terms in a sum, and we can rewrite our equation as:

4*x + x + 3 + 1 = -11

Here we also used the associative property of the sum, that says that:

A + B + C = (A + B) + C = A + ( B + C)

wich means that we can perform the sum in any order we want, then we can add the 3 and the 1

4*x + x + 4 = -11

Now we use the distributive property of the multiplication, which says that:

(A + B)*C = A*C + B*C

Then we can rewrite our equation as:

(4 + 1)*x + 4 = -11

Now we solve the sum in the parentheses to get:

5*x + 4 = -11

Now we can use the addition property of the equality, we can add (-4) in both sides to get:

5*x + 4 - 4 = -11  - 4

5*x = -15

Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:

5*x*(1/5) = -15*(1/5)

x = -5

Answer:

D: x^(6) + 27y^(9)

Step-by-step explanation:

A) 3x^(9) - 64y^(3)

The first term is raised to the power of 9 and has a coefficient which cannot also be expressed as a cube while the second term is raised to the power of 3 but has a coefficient that can be expressed as a cube. Thus the entire equation cannot be simplified to cubes as the first term cannot be expressed a cube.

B) 15x^(21) - 64y^(3)

Similar to the reason given in A above, the first term cannot be expressed as a cube.

C) 27x^(15) - 9y^(3)

In this one, the first term can be expressed as a cube while the second one cannot be expressed as a cube because 9 cannot be expressed as a cube.

D) x^(6) + 27y^(9)

This can be expressed as;

(x²)³ - (-3y³)³

This is therefore a difference of cubes

Answer:

n^2 + 6n + 1

Step-by-step explanation:

Firstly, we have to evaluate AB

What we have to do is to multiply A and B

We have this as;

n(2n + 6) = 2n^2 + 6n

Now, we have to subtract the value of C from here and that is;

(2n^2 + 6n) - (n^2 - 1)

2n^2 + 6n - n^2 + 1

= 2n^2 -n^2 + 6n + 1

= n^2 + 6n + 1

Using this information, each student can prepare an infinite number of parallelograms

Step-by-step explanation:

The given parameters of the parallelogram Emily asks the students to bring are;

The measure of one of the angles of the parallelogram = 50°

The length of of one side of the parallelogram = 10 cm

The shapes which the parallelogram must not be are; rhombus, rectangle, or square

Using the given information, therefore, the number of different parallelograms the students can prepare is given as follows;

The number of different lengths of the other side of the parallelogram = Infinity - 1 = Infinity

Therefore, the number of different parallelograms the students can prepare  is an infinite number of parallelograms

Answer:

A (first one)

Step-by-step explanation:

Supplementary- the angles add up to 180 degrees.

After viewing the angles, you can see the angles add up to 180.

Answer:

B > A

Step-by-step explanation:

B and A are both in between 0 and 1 on a number line.

On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.

Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

C. x:3 and x = 11

Answer:

Step-by-step explanation:

Total weight of the barricade is 310 kg using 8 boxes of books

Each box of books weighs 30 kg

We need to determinethe weight of the table in order write the proper equation

Total wieght of the barricade = Table Weight + Book Weight

            solving for Table Weight       substract Book Weight from both sides

Total wieght of the barricade - Book Weight  = Table Weight

                   310 - 8(30)  =  Table Weight

                   310  - 240   = Table Weight

                                70  = Table Weight

Total wieght of the barricade = Table Weight + Book Weight

                        W = 70 + 30x               where x is the number of boxes

Answer:

about 15.6cm.

Step-by-step explanation:

I got my answer of 15.6cm because I did the Pythagorean theorem.

a^2+b^2=c^2

The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.

Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.

In conclusion, the measure of the other leg is about 15.6cm.
