Amy can make 29 meatballs from the remaining beef.

What are mathematics operations?

Amy has 4 pounds of ground beef to make meatballs and he uses 3/8 pound per meatball to make 9 meatballs

We have to subtract 3/8 from 4

= 4 - 3/8

= 29/8

There are 29/8 pounds of ground beef left

Therefore the number of 1/8 pound meatball that can be produced from 29/8 pounds of ground beef can be calculated as follows;

= 29/8 ÷ 1/8

= 29

Hence Amy can make 29 meatballs

The exit mass flow rate times the exit velocity less the free stream mass flow rate times the free stream velocity equals the force (thrust).

If we take into account the factors mentioned above, we will see that if the aircraft can fly at full thrust in cruise, this fits nicely with a static sea level thrust force equivalent to one third of its weight force. The thrust required to sustain flight is approximately 1/18 of the aircraft weight.

We can load less than or equal to 285 number of 40 kg crates in the shipping container.

The inequality is like 13100 + 40x ≤ 24500

Given,

The weight of crates transported by a shipping container = 40 kg

The greatest weight that can be loaded into the container = 24500 kg

The weight of already loaded shipments in the container = 13100 kg

We have to find and solve an inequality that determines the number of 40 kg crates that can be loaded into the shipping container:

Lets take x as the number of 40 kg crates.

Therefore, weight of container = 40x

The weight should be less than or equal to the maximum weight that can be loaded into the container:

That is,

13100 + 40x ≤ 24500

Now, solve the inequality:

40x ≤ 24500 - 13100

40x ≤ 11400

x ≤ 11400/40

x ≤ 285

So,

We can load less than or equal to 285 number of 40 kg crates in the shipping container.

It should be noted that the factors of 20 are 1, 2, 4, 5, 10 and 20.

Possible sum of factors of 20 are: 3, 5, 6, 7, 9, 11, 12, 14, 15, 21, 22, and 24.

Difference between 24 and a possible sum of factors of 24 are:

The total profit made by the company over the course of its first 24 years of operation is $10,016,640

Given,

The annual profit made by a company in first year = $111,000

The increase in profit per year = 24% = $26640

We have to find the total profit made by the company over the course of its first 24 years of operation

Lets take this as an arithmetic progression.

First term, a = 111,000

Common difference, d = 26640

nth term = 24

Sum of nth term,

Sₙ = n/2 [2a + (n - 1) d]

S₂₄ = 24/2 [2 × 111,000 + (24 -1) 26640]

S₂₄ = 12 [222,000 + 23 × 26640]

S₂₄ = 12 [222,000 + 612,720]

S₂₄ = 12 × 834,720

The conditions necessary for binomial distribution is option C that is I and III only "There is a series of N trials." and "The outcomes are mutually exclusive."

In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p.

If the following circumstances hold true, the binomial distribution describes the behavior of a count variable X: 1: There will always be n observations. 2: Every observation stands alone. Three: Each observation corresponds to one of two results ("success" or "failure").

Option C, which consists solely of I and III, meets the requirements for the binomial distribution. "The results are mutually exclusive" and "There is a series of N trials."

it's so easy just use a calculator:

8h: $95.60

15h: $179.25

38h: $454.1

Answer:

Between 76 and 88

Step-by-step explanation:

the easy straight forward method is to simply sum up the 5 terms.

you know that this symbol just means "sum", right ?

and that the index variable is "running" from 1 to 5.

so, you have to sum up

3×1 + 3×2 + 3×3 + 3×4 + 3×5 = 3 + 6 + 9 + 12 + 15 = 45

now, if you want it done via a summary formula to add the first n terms of an arithmetic sequence, like in this case

a1 = 3

an = an-1 + 3 = a1×n = 3n

then

the sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).

it simply means : first plus last term added up n/2 times.

why ?

because a1 + an = a2 + an-1 = a3 + an-2 = ...

we get n/2 times such part sums.

so, in our case, n = 5, and we get

(3 + 3×5)×5/2 = (3 + 15)×5/2 = 18×5/2 = 9×5 = 45

Answer:

∑ (i = 1 to 5) (3·i)

= 3·∑ (i = 1 to 5) (i)

= 3·(1 + 2 + 3 + 4 + 5)

= 3·15

Answer: 4 and 82 i think

The simplified fraction for the expression [tex]a^{-3} / b ^{-2[/tex] is 36/125.

The exponent of a number shows how many times the number is multiplied by itself.

For example, 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power." In general, [tex]x^n[/tex] means that x is multiplied by itself for n times.

Given:

[tex]a^{-3} / b ^{-2[/tex]

Now, a= 5 and b=6

So, substituting the above values in the expression as

= [tex]5^{-3} / 6 ^{-2[/tex]

Using the law of exponents we have

[tex]a^{-m[/tex] = 1/[tex]a^m[/tex]

Thus,

= 6² / 5³

=6 x 6 / 5x 5 x 5

=36 / 125

Round to 1 significant figure

What is Rounding?

To estimate a certain number in a context, rounding is a process. Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up. The term "rounding decimals" describes the accurate rounding of decimal figures.

How to round a figure

It rounds to the most important figure in the number. To round to a significant figure: look at the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.

To understand this term lets take and example:

24982 correct to 1 significant figure

If we round up, then the answer is

30,000

but if we were to round down, the answer would be

20,000;

If we want to determine which one is correct, we have to look at the second digit of the original number, which is

4

Since the second digit is less than 5

we can round down, so the answer would have to be

20,000

Hence, 24982 round to 1 significant figure is 20,000

Answer: G=32

Step-by-step explanation:

Bella is learning to type. She typed a letter to her teacher but misspelled 8 words. If she misspelled 25% of the words she typed, how many words did she type in her letter?

_________________________________________

She misspelled 8 words = 25% of the words she typed

25%= (8 / total words)* 100

0.25 = 8 / total words

total words = 8/0.25

total words = 32

__________________________-

The total words she typed in her letter were 32

By taking the difference between the y-intercepts, we conclude that the distance between the lines is 3 units.

A general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Two linear equations are parallel if and only if both lines have the same slope and different y-intercepts.

And the distance is given by the difference between the y-intercepts.

Here the lines are:

y = -3*x + 1

y = -3*x + 4

The difference between the y-intercepts gives:

4 - 1 = 3

That is the distance between the lines.
