Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{22 \: units}}}}$ </h3>

Step-by-step explanation:

Let the points be A and B

A ( -8 , - 18 )⇒( x₁ , y₁ )

B ( 14 , -18 )⇒( x₂ , y₂)

Finding the distance between these two points

$\sf{ \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }$

Plug the values

⇒ $\sf{ \sqrt{ {(14 - ( - 8)}^{2} + {( - 18 - ( - 18))}^{2} } }$

We know that, $\sf{( - ) \times ( - ) = ( + )}$

⇒ $\sf{ \sqrt{ {(14 + 8)}^{2} + {( - 18 + 18)}^{2} } }$

Calculate

⇒ $\sf{ \sqrt{ {22}^{2} + {0}^{2} } }$

Evaluate the power

⇒ $\sf{ \sqrt{484} }$

⇒ $\sf{{22} }$ units

Hope I helped !

Best regards!!

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

Lapatulllka [165]

He pays in interest of $111.0375. Interest is calculated in the two ways, by compounding or by simple interest.

<h3>How to calculate simple interest amount?</h3>

If the initial amount (also called as principal amount) is P, and the interest rate is R % annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

$I = \dfrac{P \times R \times T}{100}$

The given data in the problem is;

The principal is,P=$2700

The rate of interest = 3.5%

The total time interval is,T

The total time interval is;

$\rm T= 5+365+31+21\ days$

The simple interest is found as;

$\rm SI = P \times R \times T \\\\ \rm SI = 2700 \times 0.0035 \times 1.172222 \\\\ SI=111.0375$

Hence, he pays in interest of $111.0375.

one angle of a linear pair is 10 more than two thirds the other angle. find the measure if both angles

BigorU [14]

Answer:

One Angle = 110°

Other Angle = 70°

Step-by-step explanation:

A linear pair means that two angles are in a straight line (or, a straight angle).

A straight line is 180 degrees.

THey are supplementary.

We can say one angle is "a" and another one is "b".

One angle is 10 MORE THAN 2/3rds of the other, we can write:

$a=\frac{2}{3}b+10$

Also, since they are supplementary (add up to 180), we can write:

a + b = 180

We can now substitute 1st equation in this one and find b:

$a+b=180\\(\frac{2}{3}b+10)+b=180\\\frac{2}{3}b+b=180-10\\\frac{5}{3}b=170\\b=\frac{170}{\frac{5}{3}}\\b=170*\frac{3}{5}\\b=110$

Since a + b = 180, we can write:

a + 110 = 180

so,

a = 180 - 110

a = 70

Thus,

One Angle = 110°

Other Angle = 70°

The half-life of a radioactive isotope is 10 years. About how long would it take 5 grams of the isotope to decay until there wer

valkas [14]

Answer:

Option A. 10 years

Step-by-step explanation:

we know that

Half-life $(t^{\frac{1}{2}})$ is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.

In this problem $(t^{\frac{1}{2}})$ of a radioactive isotope is 10 years, which means that after 10 years half of the sample would have decayed and half would be left as it is.

After 10 years ( first half life) 5/2 = 2.5 g decays and 2.5 g remains left
