<h3>Answer: x = 35</h3>

==========================================================

Explanation:

All three angles must add to 180. This is true for any triangle.

x+x+110 = 180

2x+110 = 180

2x = 180-110 ... subtract 110 from both sides

2x = 70

x = 70/2 .... divide both sides by 2

x = 35

As a check: 35+35+110 = 180 which helps confirm the answer.

Answer:

Step-by-step explanation:

x + x + 110 = 180 degree (sum of interior angles of a triangle)

2x + 110 = 180

2x = 180 - 110

x = 70/2

x = 35 degree

According to the question requirements

v= 4/3*pi*r^3

dv/dt = 4*pi*r^2*dr/dt

when
d= 1.7
r= 0.85
and
dv/dt = 2

2= 4*pi*(0.85)^2*dr/dtthus the the speed of increasing of the balloon's diameter is
dr/dt = 1/(2pi*(0.85)^2)

Carmine buys a canoe priced at $478. He pays a total, including tax, of $509.07. What was the tax rate?

Reptile [31]

Answer:

6.5%

Step-by-step explanation:

You can find the tax rate by finding the percentage that the initial price increased by.

First, subtract the initial price from the price after taxes.

509.07 - 478 = 31.07

Knowing this we can find the tax rate using an equation like this.

$\frac{Difference Between Values}{Initial Value} = \frac{x}{100}$
