I'm pretty sure it's 400w+5=s

Step-by-step explanation:

400w because thats how much he earns each week +5 because that's how much he added =s which equals the total cost in his savings

Answer and explanation:

1. In one minute, there would be zero pounds of salt in the bucket because there's 0.25 pounds of salt in one minute and 0.5 gallons of water leaves the bucket in same minute, eliminating the 0.25 pounds of salt.

2. In ten minutes there would be zero pounds of salt because theres 0.25×10= 2.5 pounds of salt and 0.5×10=5 gallons of water would leave the bucket, eliminating the salt.

3. In 60 minutes there would still be zero salt because water leaves the bucket more than salt enters

4. Zero salt too after bucket leaks

5. Zero salt

Answer:

Just please, I don't understand this at all!!!

Step-by-step explanation:

Answer:

a, t = (p - 4)/5

b. t =√(a + 4)

c. t = d/(5-f)

Step-by-step explanation:

a. p = 5t + 4

To make t the subject of the equation, subtract 4 from both sides

p - 4 = 5t + 4 - 4

p - 4 = 5t

Divide both sides by 5

(p - 4)/5 = t

t = (p - 4)/5

b. a = t2 - 4

to make t the subject, add 4 to both sides

a + 4 = t2 - 4 + 4

a + 4 = t2

find the root of both sides

t =√(a + 4)

c. d = t(5 – f)

to make t the subject, divide both sides by 5 - f

d/(5-f) = t(5 – f)/(5 – f)

t = d/(5-f)

Answer:

Surface area = 70π cm²

Step-by-step explanation:

Surface area = πr² + πrl

Surface area = (π × 5 × 5) + (π × 5 × 9)

Surface area = (25π) + (45π)

Surface area = 70π cm²

Answer:

The equation of the plane is represented by [tex]\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1[/tex].

Step-by-step explanation:

Algebraically speaking, a plane can be represented by following vectorial product:

[tex](a,b, c)\,\bullet\,(x,y,z) = 1[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Plane coeffcients.

[tex]x[/tex], [tex]y[/tex], [tex]z[/tex] - Coordinates.

We need three distinct points to determine all coefficients. If we know that [tex](x_{1},y_{1},z_{1}) = (0,9,9)[/tex], [tex](x_{2},y_{2}, z_{2}) = (9,0,9)[/tex] and [tex](x_{3},y_{3},z_{3}) = (9,9,0)[/tex], the system of equations to be solved is:

[tex]9\cdot b + 9\cdot c = 1[/tex] (1)

[tex]9\cdot a + 9\cdot c = 1[/tex] (2)

[tex]9\cdot a + 9\cdot b = 1[/tex] (3)

The solution of this system is [tex]a = \frac{1}{18}[/tex], [tex]b = \frac{1}{18}[/tex], [tex]c = \frac{1}{18}[/tex].

Hence, the equation of the plane is represented by [tex]\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1[/tex].

Answer: It really dosen't matter if its repeating. If it's repeating just put a line ABOVE THE REPEATING PART. I will explain a little bit so you know what I mean.

Step-by-step explanation: So say you divide 2 by 3 your going to get 0.66666666666. You don't have to put all those 6's. All you have to do is put 0.66 with a line above the two sixes. This will indicate you have a repeating decimal. And this works with any repeating number!

I hope this helps!!!!

Answer:

if you're trying to find z it equals 6

Step-by-step explanation:

because 60 ÷ 10 = 6

Answer:

divide 10 from z

z is alone

now divide 10 from 60

you get 6

z=6

Answer:

[tex]7x+2y = -17[/tex]

Step-by-step explanation:

We have the following equations:

[tex]2x+3y = -5[/tex]

[tex]5x-y = -12[/tex]

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

[tex](2x+5x)+(3y-y) = -5-12[/tex]

[tex]7x+2y = -17[/tex]

I hope it helps you!

Answer:

U(2, 7) → U'(-7, 2)

V(10, 7) → V'(-7, 10)

W(2, 3) → W'(-3, 2)

Step-by-step explanation:

From the picture attached,

Coordinates of the vertices of the given triangle,

U → (2, 7)

V → (10. 7)

W → (2, 3)

Since rule for the coordinates of a point P(x, y) after a rotation of 90° counterclockwise about the origin is,

P(x, y) → P'(-y, x)

Here point P is the preimage and P' is the image point after rotation.

By this rule,

U(2, 7) → U'(-7, 2)

V(10, 7) → V'(-7, 10)

W(2, 3) → W'(-3, 2)

Answer:

42%

Step-by-step explanation

Answer:correct

Step-by-step explanation:go to 1 then go up on the x axis and see that it goes to about three and do the same with three and you take the two y values and do the big number - the small number the do the same for x and you should get 22/2 and that makes a whole number of 12 BOOM

Answer:35

Step-by-step explanation:

Answer:

a) Interval containing the corresponding P-value for a two-tailed test is;

0.01  ≤ p-value ≤  0.02

b) Interval containing the corresponding P-value for a right-tailed

test is;

0.005  < p-value <  0.010

Step-by-step explanation:

Given the data in the question;

t = 2.930

df = 10

Test statistics;

Now form the t-distribution table, at df = 10, 2.930 falls between { t=2.764 and t=3.169]

so;

for a two tailed test, corresponding p-value is between: 0.02 and 0.01

For one(right) tailed test, corresponding p-value is between: 0.01 and 0.005

Therefore;

a) Interval containing the corresponding P-value for a two-tailed test is;

0.01  ≤ p-value ≤  0.02

b) Interval containing the corresponding P-value for a right-tailed

test is;

0.005  < p-value <  0.010

Answer:

(a) C = 9000 + 15N

(b) Cost of 250 widgets is $12750

Step-by-step explanation:

The question has missing details. See attachment for complete question

Solving (a): An expression for total cost.

The expression is generated using:

[tex]Total\ Cost = Fixed\ Cost + Variable\ Cost * Number\ of\ Items[/tex]

From the given parameters:

[tex]Fixed\ Cost = 9000[/tex]

[tex]Variable\ Cost = 15[/tex]

[tex]Number\ of\ Items = N[/tex]

So, the expression becomes:

[tex]C = 9000 + 15 * N[/tex]

[tex]C = 9000 + 15 N[/tex]

Solving (b): Cost of 250 widgets

In this case:

[tex]N =250[/tex]

Substitute 250 for N in [tex]C = 9000 + 15 N[/tex]

[tex]C = 9000 + 15 * 250[/tex]

[tex]C = 9000 + 3750[/tex]

[tex]C = 12750[/tex]

Answer:

5088

Step-by-step explanation:

212*24=5088

Answer:

$10 each

Step-by-step explanation:

Answer:

We want to solve:

___ + ___ + ____ = 30

using the numbers:

1, 3, 5, 7, 9, 11, 13, 15.

Now, 30 is an even number.

And the given numbers are all odd.

A random even number is written as:

2*n  (where n is an integer)

A random odd number is written as:

2*k + 1 (where k is an integer)

If we add 3 odd numbers, we get:

(2*k + 1) + (2*c + 1) + (2*j + 1) = 2*(k + c + j) + 3

= 2*(k + c + j + 1) + 1

(k + c + j + 1) is an integer, then we can write this as p

then the sum of 3 odd numbers can be written as:

2*p + 1

This means that the sum of 3 odd numers is always an odd number.

Then we can not find 3 odd numbers such that their sum is equal to 30.

if instead, we could use 4 numbers, like:

___ + ___ + ___ + ___ = 30

Then we could select:

15, 1, 5 and 9.

because:

15 + 1 + 5 + 9 = 15 + (1 + 5) + 9 = 15 + 6 + 9 = 15 + (6 + 9) = 15 + 15  = 30
