Answer:

51.

Step-by-step explanation:

When we use PEMDAS, we need to know what it stands for first. What it stands for will give us the steps necessary to complete and solve this problem.

PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

In this problem we do not have parenthesis or exponents, so we can go ahead and skip to multiplication. So:

8 x 18 ÷ 4 + 15

144 ÷ 4 + 15

Now we can go to doing division.

144 ÷ 4 + 15

36 + 15

Now we can do addition.

36 + 15

So, the answer is 51.

I hope that this helps.

336cm is 3.36m

Step-by-step explanation:

divide 336 by 100 to get to meters which is 3.36m

Answer:

[tex]\boxed{\frac{336}{1} = \frac{336}{100} = 3.36 }[/tex]

1 meter → 100 centimetres

solve:

100 centimetres → 1 meter

1 centimetres → [tex]\frac{1}{100}[/tex] meter

336 centimetres → [ [tex]\frac{1}{100}[/tex] [tex]* 336[/tex] ] meter

Step-by-step explanation:

This looks like it was written in Spanish. I can only answer you in English.

The 2 "c"s   tell you PM = MR, so QM is an angle bisector.

PQR is a right angle and = 90 degrees.

x is 1/2 PQR so x is 45 degrees

x + 10 = 45 + 10 = 55

The transformation below that caused AB to transform into A'B' is a reflection across the y-axis

Given the following coordinates

A = (6, 2)

B = (2, 6)

A' = (-6, 2)

B' = (-2, 6)

According to the reflection rule, the reflection over y axis is given as:

[tex](x,y)\rightarrow (-x,y)[/tex]

Note that the x-coordinate was negated as seen from the translation A to A' and B to '.

Hence the transformation below that caused AB to transform into A'B' is a reflection across the y-axis

When proving by induction, your first step is to show that a given claim is true for some minimal case (often called the base case). The given statement is a claim about the sum of numbers of the form 2n + 1 where n is a positive natural number. The least positive natural number is n = 1, so that seems like a reasonable place to start.

Now, we show the claim holds for n = 1:

3 + 5 + 7 + … + (2n + 1) = n (n + 2)

is a statement about an arbitrary positive integer n; the case of n = 1 reduces to

3 = 1 (1 + 2) = 1 • 3 = 3

which is obviously true.

Next, we assume that the statement is true for some arbitrary positive integer n = k, so that

3 + 5 + 7 + … + (2k + 1) = k (k + 2)

This is called the induction hypothesis.

We then use this assumption to show that the claim is also true for the next positive integer, n = k + 1. This is the claim that

3 + 5 + 7 + … + (2k + 1) + (2 (k + 1) + 1) = (k + 1) (k + 1 + 2)

or

3 + 5 + 7 + … + (2k + 1) + (2k + 3) = (k + 1) (k + 3)

By the induction hypothesis, we have

3 + 5 + 7 + … + (2k + 1) + (2k + 3)

= k (k + 2) + (2k + 3)

= k² + 2k + 2k + 3

= k² + 4k + 3

= (k + 1) (k + 3)

and this is exactly what we wanted to show, that if P(k) is true, then P(k + 1) is also true.

This means we have

P(1) = true   ⇒   P(2) = true   ⇒   P(3) = true   ⇒   …

and so on, and the claim is true for all positive integers n.

Answer:

We can break this down:

The student has a one out of five chance of getting a correct answer, and a four out of five chance of an incorrect answer. We can express the students odds of getting one incorrect answer as 4/5. In order to get the odds of two wrong answers, we need to multiply this answer again by the odds of choosing a wrong answer. Therefore:

The odds of one wrong answer = 4/5

The odds of two wrong answers = (4/5) * (4/5) = 16/25 chance of getting both of the questions wrong.

Answer: 30%

Step-by-step explanation:

Answer:

C. The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.

Step-by-step explanation:

Exponential decay is when an exponential function decreases per x-value. These functions go by a multiplier and are therefore, not linear, so you cannot add or subtract. Because the function is decaying, it is multiplying by an amount less than 1, since the multiplier is 1 - r, where r is the percent.
