what does PEMDAS mean?? lol btw if you see this and you're really good at math.. pls go check out my questions!!

Answer:

Step-by-step explanation:

1/8 + c = 4/5

c = 4/5 - 1/8

c = 4/5 × 8/8 - 1/8 × 5/5

= 32+5 / 40

= 37/40

Hope this helps

plz mark as brainliest!!!!!!

Answer:

The quantity of oil in the tank is 12,000 liters

Step-by-step explanation:

Firstly, we find the volume of the tank.

The tank is a cuboid, so we find the volume of a cuboid.

Kindly understand that when finding the volume of the cuboid, we shall not use the height of 3m.

This is because the tank is not full but it is to a height of 1.2m

So mathematically, the volume is calculated as follows;

V = l * b * h

where b = 5m , l = 2m and h = 1.2m

Thus the volume would be ;

V = 5 * 2 * 1.2

V = 12 m^3

But that’s not the quantity of oil.

From the question, 1 cubic meters contains 1000 liters of oil

So 12 cubic meter will contain = 12 * 1000 = 12,000 liters of oil

Answer:

Answer:

The answer to this in simplest radical form is 4160 2/9.

Answer:

4 monetary units

Step-by-step explanation:

In a Poisson distribution, the expected value of the distribution is the same as the mean:

[tex]E(X)=\mu=4\ claims[/tex]

The expected number of warranty claims is 4.

Since each claim results in a payment of 1, the expected value paid by the insurer is:

[tex]E(V)=E(X)*V(X)\\E(V)=4*1 = 4[/tex]

The expected total payment on warranty claims is 4 monetary units.

Answer:

14 units

Step-by-step explanation:

All we have to pay attention to in this problem is B, so we can ignore the rest of the triangle. B is 5 units directly to the left of line l, meaning that B' must be 5 units to the right of line l. This would put B' 2 units to the left of line m. That means that B" would be 2 unit to the right of line m, as that is how reflections work. Adding up all of the difference in units you have a 10 unit shift from B to B', and then a 4 unit shift from B' to B". Now adding 4+10=14 units.

Answer:

y = kx  where k>0

Step-by-step explanation:

A direct variation is in the form

y = kx

where k is a numerical positive constant ( i.e. > 0 )

Answer:

0

Step-by-step explanation:

If she puts 0 in the box she would have a direct variation.

Step-by-step explanation:

 Given : She writes the equation y = 5x - __ with a missing value.

She puts a value in the box and says that the equation represents a direct variation.

We have to choose the correct option from the given options that explain that  the equation could represent a direct variation.

When two variables are such that one is a constant multiple of other, we said they are in Direct variation.

That is in form of y = ax , here y and x are in direct variation.

Consider the given equation y = 5x  - __

For the equation to be in direct variation the value of missing term has to be 0.

then equation becomes,

y = 5x

Thus, If she puts 0 in the box she would have a direct variation.

Answer:

C) 4t + 5.75 = 65

Step-by-step explanation:

This equation is correct because it adds together the price of one popcorn and the price of the 4 tickets as 4t.

A and B are wrong because only t should be multiplied by 4, and D is wrong because it subtracts the price of the popcorn.

Answer:

A. 4(t + 5.75) = 65

Answer:

A. y = x² - 9x + 18

Step-by-step explanation:

The key thing to look for in this graph is the y-intercept (where the graph will hit the y-axis).

We can't see exactly where y-intercept is, but we know it is a positive number.

In a standard form quadratic equation:

y = ax² + bx + c

'c' tells you what the y-intercept is.

The choices with positive y-intercept are A and B.

Again, we can't see exactly where y-intercept is, but we know it is not 1.

y = x² - 9x + 18

has a positive y-intercept that is not 1,

thus the answer is A.

Answer:

See below for explanation of the examples.

Step-by-step explanation:

Left example

It is an exercise in addition, i.e. 48+122=170, the answer is written in the bottom box.

Right example

It is an exercise in subtraction, i.e. 8 1/2 - 3 1/2 = 5

The answer is written in the bottom box.

There is no indication though as to when to do the addition, and when to do the subtraction.  Perhaps it would be shown in the rest of the page (not shown).

Answer:

Step-by-step explanation:

Answer:

r = 5√2

Step-by-step explanation:

Circle Formula: (x - h)² + (y - k)² = r²

(h, k) is center, r is radius.

Since we are given 50 as r², we set equal and solve:

r² = 50

r = √50

r = 5√2

Answer:

  117

Step-by-step explanation:

Let d represent the number of stamps Derek had at first. After he gave 1/9 of his stamps to Ahmad, Ahmad had (d -104) +(d/9). Derek had 4 times this number after giving away d/9 stamps:

  (d -d/9) = 4((d -104) +d/9)

  (8/9)d = 4d -416 +(4/9)d

  416 = (32/9)d . . . . add 416 -8/9d

  117 = d . . . . . . . . . . multiply by 9/32

Derek had 117 stamps at first.

_____

Check

1/9 of Derek's collection is 13 stamps. 104 less than Derek's collection is 13 stamps.

So, Ahmad started with 13 stamps and was given 13 stamps by Derek. Meanwhile, Derek started with 117 stamps and gave away 13, so ended with 104 stamps. That number (104) is 4 times Ahmad's new number (26), as it should be.

Answer:  3/5

Step-by-step explanation:

[tex]\dfrac{a}{a+2}+\dfrac{3}{20}=\dfrac{a+3}{(a+2)+3}\\\\\\\dfrac{a}{a+2}\bigg(\dfrac{20}{20}\bigg)+\dfrac{3}{20}\bigg(\dfrac{a+2}{a+2}\bigg)=\dfrac{a+3}{a+5}\\\\\\\dfrac{23a+6}{20(a+2)}=\dfrac{a+3}{a+5}\\\\\\(23a+6)(a+5)=20(a+2)(a+3)\\\\\\23a^2+121a+30=20a^2+100a+120\\\\\\3a^2+21a-90=0\\\\\\a^2+7a-30=0\\\\\\(a+10)(a-3)=0\\\\\\a=-10\quad a=3[/tex]

Since "a" is a positive integer, disregard a = -10

So the only valid answer is a=3   →  a+2=5

[tex]\dfrac{a}{a+2}=\large\boxed{\dfrac{3}{5}}[/tex]

Answer:

D

Step-by-step explanation:

Mathematically, the mid segment of a trapezoid is exactly the average of the 2 parallel bases

What this means is that to find the length of the trapezoid, we will need to find the average of the two parallel bases

Mathematically, this is same as adding the two bases and dividing the result by 2.

Hence we can say it is exactly one-half the length of the sum of the two parallel bases
