Do you multiply area or add it

pogonyaev

It's the formula. Base times height.
For example: if 50 is the base and 10 is the height, just multiply them both.
50 x 10 = 500. And I don't think you add area-that's for finding the perimeter

How many multiples of 5 are there between 199 and 1,198? Hint: an = a1 + d(n − 1), where a1 is the first term and d is the commo

GaryK [48]

An=a1+d (n-1)
A1=200 since that's the first term that can be a multiple of 5
N=? That's what we need to find
An=1195 since that's the last multiple of 5 that we can use
D=5
Plug in
1195=200+5 (n-1)
-200 both sides
995=5 (n-1)
Distribute 5 to n-1
995=5n-5
+5 both sides
1000=5n
÷5 both sides
N=200 there are 200 multiples of 5 in between 199 and 1198

n200080 [17]

Answer:

$158.75

Step-by-step explanation:

Given:

The Maple Car Rental Comany charges a flat fee of $45 plus 35 cents per mile

And we have to write a linear equation that gives the total cost in terms of numbers of miles driven then find the total cost if the renter drives 325 miles.

Solution:

Total cost = 35 cents of renter drives in miles + fixed charge of the car

Total cost = $0.35\times325 +45$

$= 113.75 + 45\\= 158.75$

Thus, total cost is $158.75, when the renter drives 325 miles.

Solve the equation on the interval [0, 2π). cos x + 2 cos x sin x = 0

vekshin1

Take a common factor of cos(x)
$\cos(x) (1 + 2 \sin(x) ) = 0$
then by zero multplication rules
$\cos(x) = 0$
$x = \frac{\pi}{2} \: x = \frac{3\pi}{2}$
and when
$1 + 2 \sin(x) = 0$
so
$2 \sin(x ) = - 1$
$\sin(x) = \frac{ - 1}{2}$
so
$x = \frac{3\pi}{2} - \frac{\pi}{3}$
and
$x = \frac{3\pi}{2} + \frac{\pi}{3}$
