If R is inversely proportional to A, and R = 4 when A = 100, what is the value of R when A = 250 A : .625 B : 1.6 C : 10 D : 6,250

Answer:

No solution.

Step-by-step explanation:

Answer:

Step-by-step explanation:

3x + 4y = 17

5x - 4y = 7

you can thus cancel out 4y

Hence

8x = 24

Hence x = 3

Substituting’

3(3) + 4y = 17

9 + 4y = 17

Hence 17 - 9/4

= y = 2

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

im missing 50 cents somewhere its wrong but close i think sorry

The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.

Total = $37.75

Amount left = $4.00

let

37.75 = p + b + s + 4

37.75 - 4 = p + 1/6s + 3/4p

33.75 = 1/6s + 1 3/4p

33.75 = 1/6(3/4p) + 1 3/4p

33.75 = 3/24p + 7/4p

33.75 = 3+42 / 24p

33.75 = 45/24p

p = 33.75 ÷ 45/24

= 33.75 × 24/45

= 810/45

p = $18

substitute into

s = 3/4p

= 3/4 × 18

= 54/4

s = $13.5

b = 1/6s

b = 1/6 × 13.5

b = 13.5/6

b = $2.25

Answer:

C

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C

Answer:

Doesn't fit

Step-by-step explanation:

There are 2.4litres in the beaker if you count the lines; they increment by 0.4 litres each. The volume of the storage container is 20 x 15 x 7 = 2100 cm^3 (cm cubed). 1 cm^3 = 1 ml; the cube can hold 2100 mL which is 2.1 litres, which is less than the 2.4 litres in the beaker, therefore it will not fit.

This beaker will not fit into this rectangular food storage container.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since,  There are 2.4litres in the beaker, they increment by 0.4 liters each.

Hence, The volume of the storage container is,

⇒ 20 x 15 x 7

⇒ 2100 cm³

Since, Here we have;

1 cm³ = 1 ml

So, The cube hold 2100 mL which is 2.1 liters,

Clearly, It is less than 2.4 liters in the beaker.

Thus, This beaker will not fit into this rectangular food storage container.

Answer:

5(2.2y + 3.4) = 5(y - 2) + 6y

Step-by-step explanation:

In order to answer this question, one must solve each of the equations until one has reached a conclusion that the parameter (y) has no solution in the given circumstance.

Equation 1

13y + 2 - 2y = 10y + 3 - y

Simplify, combine like terms;

11y + 2 = 9y + 3

Inverse operations,

11y + 2 = 9y + 3

-9y

2y + 2 = 3

-2

2y = 1

/2

y = 0.5

Equation 2

9(3y + 7) - 2 = 3(-9y + 9)

Distribute, multiply every term inside the parenthesis by the term outside of it;

(9)(3y) + (9)(7) - 2 = (3)(-9y) + (3)(9)

Simplify,

27y + 63 - 2 = -27y + 27

27y + 61 = -27y + 27

Inverse operations,

27y + 61 = -27y + 27

+27y

54y + 61 = 27

-61

54y = 34

/54

y = [tex]\frac{17}{27}[/tex]

Equation 3

32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1

Simplify, combine like terms;

34.5y - 5.1 = 34.5y - 51

As one can see, this equation is an identity, meaning that any value can be substituted into the parameter (y) to produce a true result.

Equation 4

5(2.2y + 3.4) = 5(y - 2) + 6y

Distribute, multiply every term in the parenthesis by the term outside of it;

(5)(2.2y) + (5)(3.4) = (5)(y) + (5)(-2) + 6y

Simplify,

11y + 17 = 5y - 10 + 6y

11y + 17 = 11y - 10

Inverse operations,

11y + 17 = 11y - 10

-11y

17 = -10

One can see that this equation produces a false result since it is common knowledge that (17) cannot equal (-10). Therefore, this equation has no solutions.

Answer:

448 yd^3

Step-by-step explanation:

V = Bh  where B is l * w

V = l*w*h

V = 8* 14* 4

  =448 yd^3

Answer:

The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].

Step-by-step explanation:

From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).

Now we replace B (because we know that B is length times width) and get...

V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.

Now we just substitute the values and get...

[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]

Answer:

t = 0.0475p

Step-by-step explanation:

If

p = paycheck ; t = amount paid in state income tax

Amount contributed towards retirement :

5% of p ; 0.05p

Amount left :

Paycheck - contribution

p - 0.05p = 0.95p

Amount paid in state income tax :

5% of amount left

5% of 0.95p

5/100 * 0.95p

0.05 * 0.95p

= 0.0475p

Hence, state income tax, t = 0.0475p
