6 Work Out The Sizes Of The Angles Labelled R, S And T.Plzzzz Help I Suck At Geometry

Answers

Answer 1

Answer:

t = 30

s = 25

r = 55

Step-by-step explanation:

Let's begin by r

r is angle in quadlitral shape, so the sum of the interior angles = 360

r = 360 - (95 +100+110) = 55

Then Now it's time for  ( t )

Look at the triangle whose angles are r, 95 and t. The sum of the measures of the interior angles of triangle is 180

so t = 180 - ( 95 + r) = 180 - (95 + 55) = 30

Similarly, look at the triangle whose angles are r, s and 100

s = 180 - (100 + r) = 180 - (100 + 55) = 25

5+7/20

5 and 7/20 or 5.35

Answer:

5 7/20

Step-by-step explanation:

basically, you are going to want to turn these into improper fractions

7 3/4 = 28/4 + 3/4

        = 31/4  (no further simplification)

2 2/5 = 10/5 + 2/5

         = 12/5

now get common denominator to subtract

31/4 - 12/5

155/20 - 48/20 = 107/20

if you want this back into mixed fraction then convert

107/20 = 5 7/20

a) -34
b) 8
c) 20
d) 168

Answers

Answer: C) 20
Explanation: Subsitute (-3) into the g(x) equation so you get g(-3)= (-3)^2-1= 9-1=8
Then replace the x as 8 in f(x) and you get 3(8)-4=24-4= 20.

Answer:

4 1/12 is your answer

Find a common denominator, 12. Multiply the many times you did to the denominator to get 12 to the numerator so 3/4 would be 9/12 and 2/3 would be 8/12 so 9/12 - 8/12 is 1/12 and as you know already 10 - 6 = 4 so 4 1/12 would be your answer.

flora has a summer job where she earns $9.50 per hour. At this company, employees get a 10% raise after working for 400 hours. If flora works 640 hours over the summer, how much money will she make?

Answers

So if she works 640 hours we need to find out how much of that gets the 10% raise
640-400=240
So 240 hours get a 10% raise
400 • $9.50= $3,800
To find out how much the raise effects it
$9.50 • 10%= $0.95 + $9.50= $10.45
So the rates for the hours over 400 are $10.45
240 • $10.45=$2,508

$2,508 + $3,800= $6,308
So she made $6,308
