Explain how to determine the smaller of 0.24 and 0.3 using the number line.

1 answer:

3 0

0.24 is smaller than 0.3 because as you approach zero from the right, there's less distance from 0.24 to 0 than 0.3. Think of this in terms of limits.

Marta_Voda [28]

a) equation will be 0.5x + 3 = 18.50

b) equation will be (0.75x - 0.10x) + 3 = 21.00

<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

a) Sydney made $18.50 selling lemonade.

she sold each cup for $0.50 and received a $3 tip from a neighbor.

let x be the cost of cup she sold.

equation will be 0.5x + 3 = 18.50

b) Daria made a profit of $21.00 selling lemonade

she sold her lemonade for $0.75 per cup, received a tip of $3 from a neighbor.

equation will be (0.75x - 0.10x) + 3 = 21.00

c) Sydney don't have to pay for the cups used while Daria paid.

The quotient of the sum of 2t and 2 and twice the cube of s

Vladimir79 [104]

The equation according to the given verbal sentence is $\frac{2 t+2}{2 s^{3}}$ (after solving this $\frac{t+1}{s^{3}}$ ).

<u>Step-by-step explanation:</u>

Rewrite the given verbal sentence and so it will be easier to translate.

Given: The quotient of the sum of 2 t and 2 and twice the cube of s

sum of 2 t and 2 can be written as

2 t + 2

twice the cube of s

$2 s^{3}$

Now, combine the above according to the given verbal. The quotient of the sum of 2 t and 2 and twice the cube of s means,

2 t + 2 divided by $2 s^{3}$

Now, the equation would be $\frac{2 t+2}{2 s^{3}}$

When solving this equation, we get

$\frac{2(t+1)}{2 s^{3}}=\frac{t+1}{s^{3}}$

Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x² – 4 into the quadratic formula?

Romashka [77]

-2 = - x + x^2 -4 => x^2 - x - 4 + 2 = 0

x^2 - x - 2 = 0

a is the coefficient of x^2 => a = 1

b is the coefficient of x => b = - 1

c is the constant term => c = - 2

quadratic equation: [- b +/- √(b^2 - 4ac) ] / 2a =

= { 1 +/- √[ (-1)^2 - 4(1)(-2)] } / (2(1) = { 1 +/- √ (1 + 8) } / 2 = {1 +/- √9} / 2 =

= { 1 +/- 3} / 2
