Answer:

(a) C = 0.29t + 2.50

(b) 5

Step-by-step explanation:

The variables are defined as follows:

t = the number of toppings

C = total cost for ice cream

It is provided that:

An ice cream with no toppings is $2.50.
Every topping is priced at $0.29 each.

(a)

The algebraic equation to find the total cost for ice cream depending on the number of toppings is:

C = 0.29t + 2.50

(b)

Compute the number of toppings Mr. Torrance can buy if he wants to spend only $4.00 on it as follows:

C = 0.29t + 2.50

4.00 = 0.29t + 2.50

0.29t = 4.00 - 2.50

0.29t = 1.50

t = 5.1724

t ≈ 5

Thus, Mr. Torrance can buy 5 toppings.

Complete the proof!!!

Tamiku [17]

Answer:

The correct options are;

1. Definition of supplementary angles

2. m∠1 + m∠2 = m∠1 + m∠3

3. m∠2 = m∠3

4. Definition of congruent angles

Step-by-step explanation:

The two column proof is presented as follows;

Statement ${}$ Reason

1. ∠1 and ∠2 are supplementary ${}$ Given

∠1 and ∠3 are supplementary ${}$

2. m∠1 + m∠2 = 180° ${}$ (1) Definition of supplementary angles

m∠1 + m∠3 = 180°

3. (2) m∠1 + m∠2 = m∠1 + m∠3 ${}$ Transitive Property

4. (3) m∠2 = m∠3 ${}$ Subtraction property of equality

5. ∠2 ≅ ∠3 ${}$ (4) Definition of congruent angles

Given that angles ∠1 and ∠2 are supplementary, we have, ∠1 + ∠2 = 180°

Given that angles ∠1 and ∠3 are also supplementary, we also have, ∠1 + ∠3 = 180°

∴ ∠1 + ∠2 = 180° = ∠1 + ∠3

∠1 + ∠2 = ∠1 + ∠3

∠1 + ∠2 - ∠1 = ∠1 + ∠3 - ∠1

∴ ∠2 = ∠3

∴ ∠2 ≅ ∠3, by definition of congruent angles.

PLEASE HELP ME OUT!!

Zielflug [23.3K]

Answer:

(d) 1/√(s³)

Step-by-step explanation:

The expression can be simplified by making use of the rules of exponents.

<h3>Rules of exponents</h3>

The relevant rules are ...

$a^b\cdot a^c=a^{b+c}\\\\(a^b)^c=a^{bc}\\\\\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}\\\\a^{b/c}=\sqrt[c]{a^b}$

<h3>Application</h3>

The given expression can be simplified by applying these rules.

$\left(\dfrac{1}{s^{-1}\cdot s^8}\right)^{3/14}=\dfrac{1}{(s^{-1+8})^{3/14}}=\dfrac{1}{s^{7\cdot3/14}}=\dfrac{1}{s^{3/2}}=\boxed{\dfrac{1}{\sqrt{s^3}}}$

Which is an equation of a direct proportion? a.y=1/6x+6 b.y=6/x c.y=6x-6 d.y=6x

Amanda [17]

Answer:

Option D. y=6x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each case

case a) y=(1/6)x+6

Is a linear equation, but is not a direct variation. The line not passes through the origin

case b) y=6/x

The equation represent an inverse variation

case c) y=6x-6

Is a linear equation, but is not a direct variation. The line not passes through the origin

case d) y=6x

The equation represent a direct variation
