Answer:

About 5.5% decrease

Step-by-step explanation:

Here, we want to calculate the percentage increase or decrease and its value.

The first thing to do here is to check if we are going to have a decrease or an increase.

since the value before the change is higher than the value after the change, then what we have is a decrease.

Mathematically, the percentage decrease is calculated as follows;

% decrease = (old value - new value)/old value * 100%

old value = 163 feet

new value = 154 feet

% decrease = (154-163)/163 * 100%

% decrease = -9/163 * 100%

% decrease = -5.52%

Thus the best answer is about 5.5% decrease

What is the radius of the circle given by the equation below? x2 - 2x + y2 - 2y - 98 = 0?
valina [46]
Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²

Now the equation is in the form (x - h)² + (y - k)² = r²

Radius = 10

Use the Pythagorean theorem to find the unknown side of the right<br>triangle​
kramer

Answer:

26

Step-by-step explanation:

→ Utilise Pythagoras theorem

a² + b² = c²

→ Substitute in the values

10² + 24² = c²

→ Simplify

100 + 576 = c²

→ Simplify further

676 = c²

→ Square root both sides to isolate c

26 = c

An account earns simple interest. $1675 at 4.6% for 4 years a. Find the interest earned. $___ b. Find the balance of the account
Colt1911 [192]
A. First, divide 1675 by 100 to find 1% of it. 
1675 / 100 = 16.75 
Then, multiply 16.75 by 4.6 to get 4.6%. 
16.75 x 4.6 = 77.05 
77.05 is the interest for one year. 
Multiply it by 4 to get the interest for 4 years. 
77.05 x 4 = 308.20 
The interest earned is $308.20. 

B. Add the interest to the original balance to get the total. 
308.20 + 1675 = 1983.20 
The balance of the account is $1983.20 after 4 years. 

Hope this help!

Angles a and b are supplementary how would you fix value of x
kotykmax [81]

Answer: 180 = 30 + (x + 60)

Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
