Answer:

$\boxed {s = 5.1}$

Step-by-step explanation:

Solve for the value of $s$ :

$0.7(3s + 4) - 1.1s = 7.9$

-Use Distributive Property:

$0.7(3s + 4) - 1.1s = 7.9$

$2.1s + 2.8 - 1.1s = 7.9$

-Combine like terms:

$2.1s + 2.8 - 1.1s = 7.9$

$s + 2.8 = 7.9$

-Subtract $2.8$ to both sides:

$s + 2.8 - 2.8 = 7.9 - 2.8$

$\boxed {s = 5.1}$

So, the value of $x$ is $5.1$ .

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

Use the pythagorean theorem to write an equation for the distance Jane's trainer bikes.

ankoles [38]

Complete question is;

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet jane at the end of her run. Use the pythagorean theorem to write an equation for the distance janes trainer bikes

Answer:

x = √(12² + 16²)

Step-by-step explanation:

We are told that;

She bikes from health club to South = 16 miles

From South to West = 12 miles

Her trainer bikes from the health club to meet her at the end which is west.

I have attached a diagram showing this movement in form of a triangle.

From the diagram I attached, I have depicted the distance the trainer bikes as x.

Using pythagoras theorem;

x² = 12² + 16²

x = √(12² + 16²)

explain why you can or cannot figure out the shape of a tank if you only know how many gallons it holds

jolli1 [7]

You certainly cannot. This is because you can really only determine size from how many gallons it holds, and shape can differ as long as it can hold the amount needed. Hope this helps.

I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t

igomit [66]

Answer:

The tax on property assessed at $660,000 is $13860 .

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, we need to get the tax rate of Atlanta first.

Tax Rate = Tax / Property assessed × 100.

$Tax\ rate=\frac{19530}{930000} \times 100$

$Tax\ rate=0.021 \times 100$

$Tax\ rate=2.1\%$

According to question the tax rates are proportional.

So, for getting the tax in this city we use the same rate of Atlanta:

Tax = tax rate of property assessed.

$Tax = 2.1\% of\ \$660,000$

$Tax = \frac{2.1}{100}\times 660000.$

$Tax = 0.021\times 660000$

$Tax=\$13860$

Therefore, the tax on property assessed at $660,000 is $13860.

The area of triangle ABC is _____.

Marizza181 [45]

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
SEE ATTACHED IMAGE.
Using Heron's Formula we can find the area of the triangle.
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Where,
s: semi-perimeter
a, b, c: sides of the triangle
Substituting values:
s = (15 + 16 + 20) / 2
s = 25.5
s = 26
The area will be:
A = root (26 * (26-15) * (26-16) * (26-20))
A = 130.9961832
A = 130 u ^ 2
Answer:
The area of triangle ABC is:
C.
130 u ^ 2
