Answer:

14

Step-by-step explanation:

13-2=11 then 11x 3 =33 then 33-25=8+=14

Answer:

Step-by-step explanation:

PEMDAS is going to be your best friend bud. It stands for Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction. This is the order you will use for all problems like this in the future. Start by solving everything inside the parenthesis.

6+3(11)-5^2=?

Now that all the parenthesis are gone we move on to exponents.

6+3(11)-(5*5)=?

6+3(11)-25=?

Now that all exponents are gone we solve for multiplication and division, whichever comes first when reading from left to right.

6+33-25=?

The final step is to add and subtract from left to right.

Hope this helps!

I am not sure if you were serious with this question or not but here is the answer lulu

hope this helps :) :) :) :)

I'm guessing ordinary language means not in scientific method and in words. So...

First we combine the exponent because they are multiplied with the same base getting...

10^2+5=10^7

Now we can convert this into everyday numbers...

10,000,000

Or...

10 million

Since I do not know what ordinary language means to your teacher, just choose the answer that is the one your teacher wants! If you have any more questions about this just ask in the comments.

Answer:

$54 because the tip would be $9 so just add 45 and 9

Answer:

$54

Step-by-step explanation:

Since we are adding a 20% tip to the original cost of 45, the equation is

45+(0.2)(45),

since we want to add 20% of 45 to the original 45.

Solving that gives us 54.

Answer:

The estimate for the amount of tails is 146.

Step-by-step explanation:

For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The probability of a head is 0.27.

This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]

The coin is thrown 200 times.

This means that [tex]n = 200[/tex]

Write an estimate for the amount of tails

This is the expected value, so:

[tex]E(X) = np = 200*0.73 = 146[/tex]

The estimate for the amount of tails is 146.

Answer:

[tex]y = 2000(1.05)^{36[/tex]

Step-by-step explanation:

Given

[tex]a = 2000[/tex] -- Initial population

[tex]r = 5\%[/tex] --- Rate (monthly)

Required

Determine the population in 3 years

The question shows an exponential distribution and the final population will be calculated using:

[tex]y = a(1 + r)^x[/tex]

Where x is the number of months.

[tex]x = 3\ years[/tex]

[tex]x = 3* 12\ months[/tex]

[tex]x = 36[/tex]

So, we have:

[tex]y = 2000(1 + 5\%)^{36[/tex]

Convert % to decimal

[tex]y = 2000(1 + 0.05)^{36[/tex]

[tex]y = 2000(1.05)^{36[/tex]

(c) is correct

Answer:

[tex]\frac{1}{5}[/tex] = [tex]\frac{2}{10}[/tex] = [tex]\frac{20}{100}[/tex]

Step-by-step explanation:

It's all about equivalent fractions.

[tex]\frac{1}{5}[/tex]

[tex]\frac{2}{10}[/tex]

[tex]\frac{20}{100}[/tex]

[tex]\frac{1}{5}[/tex] 1 × 2 = 2. 5 × 2 = 10. That is what makes [tex]\frac{2}{10}[/tex].

[tex]\frac{2}{10}[/tex] 2 × 10 = 20. 10 × 10 = 100. That is what makes [tex]\frac{20}{100}[/tex].

Answer:

let me help you,first let do the red one:

-9(2)=-18

2-9=-7

-5+12=7

-2(-8)=16

-36÷12=-3

32÷(-2)=-16

-9-(-4)=-5

-7+(-3)=-10

9+(-6)=3

-3(5)=-15

now the green one:

-8-10=-18

19+(-3)=16

-12÷(-4)=3

5(-1)=-5

-8+5=-3

-22+7=-15

-17+10=-7

-8(2)=-16

-8-2=-10

-35÷(-5)=7

Step-by-step explanation:

For these expression you will be able to find the same number.

Answer:

A. $1,810, B. $16,290

Step-by-step explanation:

A. $18,100 * 0.10 = $1,810

B. $18,100 - $1810= $16,290

Answer:

A. 6

Step-by-step explanation:

The equation should equal 20 so first subtract 2 from 20 which is 18 then divide 18 by 3 which is 6, 6 is your answer.

Opposite angles are equal

[tex]\\ \sf\longmapsto 3x+2=20[/tex]

[tex]\\ \sf\longmapsto 3x=20-2[/tex]

[tex]\\ \sf\longmapsto 3x=18[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{18}{3}[/tex]

[tex]\\ \sf\longmapsto x=6[/tex?

Answer:

x>10,x<−5

Step-by-step explanation:

[tex]x > - 5[/tex] or [tex]x < 10[/tex] are the two possible solutions to the given  inequality.

An absolute value function is a function that contains an algebraic expression within absolute value symbols.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

According to the given question.

We have an inequality |3x| > x + 20

Solve the above given inequality |3x| > x + 20

⇒ [tex]-(x + 20) < 3x < +( x + 20)[/tex]

⇒ [tex]-x -20 < 3x < x + 20[/tex]

⇒ [tex]3x > -x -20[/tex] or [tex]3x < x + 20[/tex]

⇒ [tex]3x+x > -20[/tex] or [tex]3x - x < 20[/tex]

⇒ [tex]4x > -20[/tex] or [tex]2x < 20[/tex]

⇒[tex]x > -5[/tex] or [tex]x < 10[/tex]

⇒ x ∈ (-∞, -5)∪(10,∞)

Hence, [tex]x > - 5[/tex] or [tex]x < 10[/tex] are the two possible solutions to the given  inequality.
