A Furniture maker used 9/10 of a can of paint to paint 9 chairs. she used the same amount of paint for each chair. How many cans of paint did she use for each chair in

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:

70% of 300 is 210

Answer:

70.028175

Step-by-step explanation:

To convert a radian measurement to a degree measurement, multiply the angle by the conversion ratio.

degrees = radians ×  (57.29578 or 180/pi)

11/9 rad = 70.028175°

0.42 = 42/100

to find percent you need to find how much is it out of 100

42/100 = 42%. :)

Answer:

42%

Step-by-step explanation:

If you have a hard time determining how to calculate a decimal into a percentage, just move the number to places to the left.

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

Answer:

18 I believe

Step-by-step explanation:

72/4

Answer:

each friend got 18 bows

to find how many bows each friend got;

total ÷ amount of friends=

72÷4 = 18

(to find amount she gave her friends individually;

amount each friend got - amount her mom gave them

= 18-6=12)

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:

Step-by-step explanation:

this is a rational function thus the domain is all real numbers except the values which make zero to denominator

hence x-4=0 ;x=4

the domain of that function is R- {4}

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:

(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: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:

Answer:

multiply 3 by both numbers in the parenthesis (answer is 30)

Step-by-step explanation:

3(4+6) you would do 3*4 and 3*6 so 12 and 18 add them you get 30

Answer:35

Step-by-step explanation:

Answer: 2 cakes.

Step-by-step explanation:

There will be a total number of 6 people at Eli's cake party.

You want that each one of these 6 people to eat at least 1/5 of a cake.

Then you need to make, at least, 6 times 1/5 of a cake.

This is equal to:

6*(1/5) of a cake = 6/5 of a cake.

And we can rewrite this as:

(6/5) of a cake = (5 + 1)/5 of a cake = (5/5 + 1/5) of a cake = 1 cake + 1/5 of a cake.

But you can not bake only 1/5 of a cake, we need whole numbers.

Then we need to round up to the next whole number, which is 2.

This means that you need to bake at least 2 cakes.

100(137.94)= 13,794

13,794/229.9= 60, 60%

6.

[tex]\frac{616.55}{x}=\frac{5}{100}[/tex]

100(616.55)= 61,655

61,655/5= 12,331, $12,331

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:

[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]
