Answer:

m<A = 36 degrees

Step-by-step explanation:

we know that the top angle is 90 degrees and so (x+46) + (x + 66) = 90

simplify and we get 2x + 110 = 90

x = -10

substitute -10 for x

m<A = (-10) + 46

m<A = 36

On Monday, Maggle ran n miles. On Tuesday, she ran 90% of the number of miles that she ran on Monday. On Wednesday, she ran 50%

Nimfa-mama [501]

Answer:

$Total = 2.35n$

Step-by-step explanation:

Given

Monday = n

Tuesday = 90% of Monday

Wednesday = 50% of Tuesday

Required

Determine the total miles

We have:

Tuesday = 90% of Monday

Substitute n for Monday

Tuesday = 90% of n

$Tuesday = 90\% * n$

Express percentage to decimal

$Tuesday = 0.90 * n$

$Tuesday = 0.90n$

We also have that:

Wednesday = 50% of Tuesday

Wednesday = 50% * Tuesday

Substitute 0.90n for Tuesday

$Wednesday = 50\% * 0.90n$

Express percentage to decimal

$Wednesday = 0.50 * 0.90n$

$Wednesday = 0.45n$

The total number of miles is:

$Total = Monday + Tuesday + Wednesday$

$Total = n + 0.90n + 0.45n$

$Total = 2.35n$
