$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{-6})~\hspace{10em} slope = m\implies -\cfrac{3}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-6)=-\cfrac{3}{4}(x-4) \\\\\\ y+6=-\cfrac{3}{4}x+3\implies y=-\cfrac{3}{4}x-3$

1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is th

Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

$I=Prt$

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

$I=Pr(3)\\$

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

$I=\frac{Pr(4)}{12}$

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

$I=\frac{Pr(45)}{365}$

Find the measurement of angle 7

Inessa [10]

Answer:

76 degrees

Step-by-step explanation:

find angle 5 by subtracting 76 from 180 to get 104 degrees

the find angle 7 by subtracting 104 from 180 to get 76

180-76 =104

180-104=76

Elizabeth bought a cheese pizza. It was served on a metal tray with a diameter of 22 centimeters. What is the tray's area?

agasfer [191]

<h3>Answer:</h3>

The Area of the tray ≈380 cm

<h3>Solution:</h3>

We are given the diameter of the tray, which is equivalent to 22 cm.
We are asked to find the area of the tray.
Remember the formula:
Area of a circle = πr²
Where
π -> pi (3.14...)
r -> radius
Notice that we aren't given the radius. We're given the diameter only.
No reason to panic. We can easily find the radius by dividing the diameter by 2.
The radius is equal to 11 cm.
Now, plug the values into the formula:
A=π(11)²
A=121π
A≈380 cm

Hope it helps.
