Answer:

A farmer keeps a record of the weekly milk yield of his herd of seven cows over a period of six months. He finds that the mean yield is 24 liters. He buys another cow that he is told will produce 28 liters of milk a week. Work out the effect this will have on the mean milk yield of his cows.​

Step-by-step explanation:

Hope it helps<3

Answer:

24.5 liters/week

Step-by-step explanation:

24 liters/week for 7 cows is 168 liters/week

Add 1 cow that produces 28 liters/week

The new total is 196 liters/week for 8 cows

(196 liters/week for 8 cows)/(8 cows) = 24.5 liters/week is the new mean.

Answer: X = -24 Y = 66

Step-by-step explanation:

Step-by-step explanation:

Given the following question:

10% of 2,000,000

An app brought in $2 million in revenue before giving 10% of that revenue to pay for prizes. We need to find how much revenue did the app earn AFTER the store paid for the reward prizes.

[tex]\frac{10\times2000000}{100} =10\times2000000=20000000\div100=200000[/tex]
10% of 2 million is 200,000.
[tex]2000000-200000=1800000[/tex]

The app earned "$1.8 million" after paying for the reward prizes.

Answer:

x = 7.48

Step-by-step explanation:

You need to use the Pythagorean theorem to solve this problem.

leg^2 + leg^2 = hypotenuse^2

a^2 + b^2 = c^2

5^2 + x^2 = 9^2

25 + x^2 = 81

subtract 25 from both sides.

x^2 = 81 - 25

x^2 = 56

Square root both sides.

x = sqroot(56)

x = 7.48

Answer:

7

Step-by-step explanation:

love is = 4, because love + love = 8 meaning its 4+4

heart is = 5, because heart - 4(love) = 1

bird is = 3, because bear is = 9 since 5(heart) + 4(love) is bear, and 3 birds make  a bear.

Answer:

17

8 ÷ 2 = 4. love = 4.

heart - 4 = 1. heart = 5.

love 4 + heart 5 =9. bear =9

9÷3=3. birds = 3.

Answer:

A to B = 2000 m/s

C to D = 30,000m/s

Step-by-step explanation:

A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s

C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s

Answer:

a to b is 20m/s I'm in k12 and I got the same question but I don't know for c to d yet

Step-by-step explanation:

A =0

B=200

T=10s

200 divided by 10 is 20m/s

Answer:

6 $1 bills, 5 $5 bills

Step-by-step explanation:

Say the student has x $1 bills.

Then they have 11 - x $5 bills.

31 = 1 * x + (11 - x) * 5 = 55 - 4x

4x = 55 - 31 = 24

x = 6

So, they have 6 $1 bills and 11 - 6 = 5 $5 bills

Answer:

5, 5, 5, 5, 5, 1, 1, 1, 1, 1, 1. As you see those are eleven numbers/bills so your answer may be, The student has 5, 5$ bills and 6, 1$ bills. which makes up 31$.

Answer:

$90.18 dollars

Step-by-step explanation:

Given the following question:
Original cost = $83.50
Sales tax = 8%

In order to find the price paid for the chair, we find 8 percent of the original price. Then we add that number to the $83.50 for the chair and then we will have our answer.

[tex]\frac{8\times83.5}{100} =8\times83.5=668\div100=6.68[/tex]

Sales tax of the chair is $6.68.

[tex]83.50+6.68=90.18[/tex]

Total cost of the chair after an 8 percent sales tax is "$90.18 dollars."

Hope this helps.

Answer:

Tom should use a ladder that is smaller or at the the same height of the window frame. Here it says that he is using a ladder that is taller than the window frame, and this can be very uncomfortable for the person who is using the ladder, so it would be recommendable for Tom to use a smaller ladder, probably a ladder that is only a few inches smaller or taller than the window frame. Using a ladder that is like this should be safe to use.

Answer:

Jack's fathers work is 1350 miles away from home

Step-by-step explanation:

Equation for trip 1:

Usual speed=x

Time=30 minutes

Formula for distance: d=st

d=30x

Equation for trip 2:

Speed= x-30

Time=90 minutes

d=90(x-30)

Now we solve for x using simultaneous equations:

30x=90(x-30)

x=45

Now to find d we sub in our new found value into one of the two equations (it doesn't matter which one)

d=30(45)

d=1350 miles

Remainder theorem tells about the remainder of division of a polynomial with x - a. The roots of given function are: 1, -1, -3

If there is a polynomial p(x), and a constant number 'a', then

[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)[/tex]

where g(x) is a factor of p(x)

For the given case, we've got:

[tex]f(x) = x^3 + 3x^2 -x - 3[/tex]

and

f(1) = 0

Thus, for a = 1, from remainder theorem, we get:

[tex]\dfrac{p(x)}{(x-a)} = g(x) + p(a)\\\\\dfrac{f(x)}{(x-1)} = g(x) + f(1)\\\\\dfrac{x^3 + 3x^2 - x - 3}{(x-1)} = g(x) + 0\\\\ \dfrac{x^2(x+3) -1(x+3)}{x-1} = \dfrac{(x^2-1)(x+3)}{(x-1)} = g(x)\\\\(x+1)(x+3) = g(x)[/tex]

Thus, the other factor of f(x) is g(x) = (x+1)(x+3)

And we have:

[tex]\dfrac{f(x)}{x-1} = g(x)\\\\f(x) = (x+1)(x+3)(x-1)[/tex]

Putting it equal to 0, we get:

[tex]f(x) = 0\\(x+1)(x+3)(x-1) = 0\\x = 1, -1, -3[/tex]

Thus,

The roots of given function are: 1, -1, -3

The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions thus option (d) is correct.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Gross income = $85,463

Deductions are,

Income will be $896

Exemptions is 2 x $3,650

Charitable donations is $2,145

Exemptions is 2 x $3,650 expenses is $3,473

Add all above the deduction to find out the total deduction,

$896 + $2,145 + $3,473 + 2 x $3,650 = $13,814

Thus, net income will be as by subtraction,

$85,463 - $13,814 = $66,129

Hence "The net salary after all deductions will be $66,129 and can be calculated by subtraction of gross salary from all deductions".
