Answer:

2x² + 9x - 5

Step-by-step explanation:

Given

(2x - 1)(x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 5) - 1(x + 5) ← distribute both parenthesis

= 2x² + 10x - x - 5 ← collect like terms

= 2x² + 9x - 5

Step-by-step explanation:

15×80/100

15×8/10

120/10

12 kg

Answer:

12kg

Step-by-step explanation:

When finding 15% of something you can set it up like this

?      15

---    ----

80  1000

to figure out what the '?' is you need to multiply diagonally and divide the neighbor

80 x 15 = 1200

1200 / 100 = 12

Hence, your answer is 12 kg

Answer:

  524,160

Step-by-step explanation:

Assuming order matters, it is the number of permutations of 16 things taken 5 at a time:

  16P5 = 16!/(16-5)! = 16·15·14·13·12 = 524,160

The first passenger can pick any of 16 seats; the second can pick any of 15 remaining seats; and so on until all 5 passengers have chosen a seat. The number of possible different arrangements is the number shown above.

Answer:

1:4

Step-by-step explanation:you can simplify the ratio by finding the LCM on both sides and dividing the number by the lcm in which this case is 15.

15/15=1

60/15=4

so 1:4

The answer to the question is 1:4

Step-by-Step explanation:

We have to divide each number over here by the LCF of 15.

The LCF (Least Common Factor) of 15 is 5.

Given the LCF of 15 is 15, we will divide both given numbers by 15.

[tex]\text {60 / 15 = 4 and 15 / 15 = 1}[/tex]

We will put the numbers back in order from least to greatest.

The ratio we find is 1:4, and the answer to your question is 1:4.

Answer:

x=0.2(y+2)

Step-by-step explanation:

After expanding the given expression, the result obtained is equal to 0.2y + 0.4.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. A mathematical operation like reduction, addition, multiplication, or division is used to include terms in an expression.

As per the given expression in the question,

0.2(y + 2)

Now, multiply 0.2 by each value present inside the bracket,

So, the expanded form will be,

0.2y + 0.4

The Zscore for both test is the same

Step-by-step explanation:

Given that :

TEST 1:

score (x) = 75

Mean (m) = 65

Standard deviation (s) = 8

TEST 2:

score (x) = 75

Mean (m) = 70

Standard deviation (s) = 4

USING the relation to obtain the standardized score :

Zscore = (x - m) / s

TEST 1:

Zscore = (75 - 65) / 8

Zscore = 10/8

Zscore = 1.25

TEST 2:

Zscore = (75 - 70) / 4

Zscore = 5/4

Zscore = 1.25

The standardized score for both test is the same.

Answer:

I think the question you are trying to say is . . . A baker bought some flower. He used 2/5 of the flour to make bread and used the rest to make batches of muffins. If he used 16lb of flour making bread and 2/3 lb for each batch of muffins, how many batches of muffins did he make?

So I have provided the answer and explanation below.

Step-by-step explanation:

He make 36 batches of muffins.

Consider the provided information.

It is given that he used 2/5 of the flour for bread, and he used 16lbs for bread.

Let total amount of flour is x lbs, now convert above statement into mathematical form.

2/5 x = 16

2x/5 = 16

x = 5 • 16/2 = 80/2

x = 40

Therefore, he bought 40 lbs of flour.

He used 16 lb out of 40.

So for muffins he left with 40-16=24 lbs of flour.

It is given that he used 2/3 lb. For each batch of muffins.

Divide 24 with 2/3 lb.

24/2/3 = 24 • 3/2

72/2 = 36

Hence, he make 36 batches of muffins.

The missing length is 8

Step-by-step explanation:

Represent the missing length with x

The non-parallel sides of the given shape are directly proportional.

Mathematically:

3 to 6 and 4 to x

Represent as a ratio:

[tex]3 : 6 = 4 : x[/tex]

Convert to fraction

[tex]\frac{3}{6} = \frac{4}{x}[/tex]

Cross Multiply:

[tex]3 * x = 6 * 4[/tex]

[tex]3x = 24[/tex]

Divide through by 3

[tex]x = \frac{24}{3}[/tex]

[tex]x = 8[/tex]

The length of the missing side is 8

Answer:

-x^2 - 11x -30

Step-by-step explanation:

Solve using foiling. Ignore the -1 to begin with and just look at the part in parenthesis. Do x from the first parenthesis times the stuff in the second parenthesis.

ie: x(x) and x(6)

ie: x^2 + 6x

Then do the 5 times the things in the second parenthesis.

ie: 5(x) and 5(6)

ie: 5x + 30

Then add what you got from multiplying the first value to what you got from multiplying the second.

ie: x^2 + 11x + 30

This is a trinomial because it has three different variables. Now change all the signs to negative because of the -1 out front.

ie: -x^2 - 11x -30

Answer:

Mauricio's score for each event is 7.

Step-by-step explanation:

Mauricio scored a total of 34.42 points in five gymnastic  events.

We can round off his score as 35.

To find Mauricio's score for each event, divide total score and no of events as follows :

[tex]n=\dfrac{35}{5}\\\\=7[/tex]

Hence, Mauricio's score for each event is 7.
