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.

Answer:

average = 9

(the third number is the average)

Step-by-step explanation:

If the sum of three numbers is 27, then the average (mean) is the total (27) divided by the number of values (3):

⇒  27 ÷ 3 = 9

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

However, if you want to find the actual numbers:

Let x = first number

Let y = second number

Let z = third number

Given:

Substitute y = 3x  and  z = 2x  into  x + y + z = 27 and solve for x:

⇒ x + 3x + 2x = 27

⇒ 6x = 27

⇒ x = 4.5

    y = 3x  

⇒  y = 3 x 4.5

⇒  y =13.5

    z = 2x

⇒  z = 2 x 4.5

⇒  z = 9

Therefore, x = 4.5  y = 13.5  and z = 9

which means z (the third number) is same value as the average

Answer:

22 stickers in each box

Step-by-step explanation:

Ling Ling = 587 stickers

Jia = 245 stickers

Therefore, total number of stickers = 587 + 245 = 832

if they gave 40 stickers to their cousin, then

remaining stickers = 832 - 40 = 792

If they put the remaining 792 stickers equally into 36 boxes, then

number of stickers in each box = 792 ÷ 36 = 22

Answer: 4/41?

Step-by-step explanation:

Is that what you wanted?

Or do you need it as a percentage?

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.

Step-by-step explanation:

a = amount that paid 11% profits

b = amount that lost 5% profits

we know that whatever those values are, a + b = 28000.

how much is 11% of "a"? well, (11/100) * a = 0.11a.

how much is 5% of "b"? well (5/100) * b = 0.05b.

[tex]a+b=28000\implies b=28000 - a \\\\[-0.35em] ~\dotfill\\\\ \stackrel{paid~11\%}{0.11a}~~ \stackrel{\stackrel{loss}{\downarrow }}{-} ~~\stackrel{lost~5\%}{0.05b}~~ = ~~\stackrel{overall~paid}{2920} \\\\\\ \stackrel{\textit{substituting on the 2nd equation}}{0.11a~~ - ~~0.05(28000-a)}=2920\implies 0.11a+0.05a-1400=2920 \\\\\\ 0.16a-1400=2920\implies 0.16a=4320\implies a=\cfrac{4320}{0.16} \\\\\\ \boxed{a=27000}~\hspace{10em}\boxed{\stackrel{28000-a}{b=1000}}[/tex]

Step-by-step explanation:

hope this helps you :)

Answer:

Step-by-step explanation:

First of all, you add 1/3 and 4/5, so you get:

To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:

Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:

That's the sum of 1/3 + 4/5.

Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:

In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:

Since 119 and 15 don't have a common factor, so they can't be simplified.

So, the answer is 119/15.

Hope this Helps! :D

B if not C, with the exponent of the coefficient

The factorization of the trinomial is A = 3 ( x - 2 ) ( x - 5 )

Brackets should be expanded in the following ways to factorize an expression

For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket

For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.

Given data ,

Let the expression be represented as A

Now , the value of A is

A = 3x² - 21x + 30   be equation (1)

On simplifying , we get

Taking 3 as the common factor of the expression , we get

A = 3 ( x² - 7x + 10 )

A = 3 ( x² - 2x - 5x + 10 )

On factorizing , we get

A = 3 ( x - 2 ) ( x - 5 )

Hence , the expression is A = 3 ( x - 2 ) ( x - 5 )

Answer:

for (−4/5)x + 3/10 < 8/10:  solution is x > -5/8

for −4/(5x) + 3/10 < 8/10: solution is x > -8/5

Step-by-step explanation:

I'm not exactly sure if you mean -4 divided by 5x or (-4/5)x, so I've done both! :)

[tex]-\frac{4}{5}x+ \frac{3}{10} < \frac{8}{10}[/tex]

subtract 3/10 from both sides:  [tex]-\frac{4}{5}x < \frac{5}{10}[/tex]

Divide both sides by 4/5:  [tex]-x < \frac{5}{8}[/tex]

Divide both sides by -1 (reverse sign):  [tex]x > -\frac{5}{8}[/tex]

[tex]-\frac{4}{5x}+ \frac{3}{10} < \frac{8}{10}[/tex]

subtract 3/10 from both sides:  [tex]-\frac{4}{5x} < \frac{5}{10}[/tex]

Multiply both sides by 5x:  [tex]-4 < \frac{5}{2}x[/tex]

Divide both sides by 5/2:  [tex]x>- \frac{8}{5}[/tex]

YoungBoy

Answer:

x = 52°

y = 128°

Step-by-step explanation:

This is an isosceles trapezoid as the legs are the same length (denoted by the double dashes).

For an isosceles trapezoid, the sets of angles adjoined by parallel lines are equal.  Therefore, for this trapezoid, y = 128 and the two remaining angles are both x.

The interior angles of a trapezoid = 360°

Therefore, x + x + 128 + y = 360

Since we know y = 128:

2x + 128 + 128 = 360

⇒ 2x = 104

⇒ x = 104 ÷ 2 = 52

Using the normal distribution, it is found that the the travel time such that 26.11% of the 60 days have a travel time that is at least is of 42.19 minutes.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

The travel time such that 26.11% of the 60 days have a travel time that is at least X when Z has a p-value of 1 - 0.2611 = 0.7389, hence X when Z = 0.64, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.64 = \frac{X - 35.6}{10.3}[/tex]

[tex]X - 35.6 = 0.64(10.3)[/tex]

[tex]X = 42.19[/tex]
