Answer:
$3 for Syd and $5 for Mark
Step-by-step explanation:
when Mark worked 8 hours and Syd worked 10 hours they earned $80
when Mark worked 9h Syd worked 5h they earned $65
we can make a equation out of these information
8M + 10S = $80
9M + 5S = $65 we can use the systems of equations by eliminating method
multiply second equation by -2
-2 × (9M + 5S) = $65
-18M - 10S = -$130 now add up the new equation with the first one
8M + 10S - 18M - 10S = $80 - $130 (10S will eliminate -10S)
-10M = -$50
10M = $50
M = $5
we can use hourly rate we found for M (Mark) to find the hourly rate for S (Syd)
9×5 + 5S = $65
45 + 5S = $65
5S = $15
S = $3

Answer:</h3>
67 miles
<h3>
Step-by-step explanation:</h3>
On Monday, Jullo ran <u>39 miles.</u>
On Tuesday, he ran <u>24 miles.</u>
On Wednesday, he ran <u>4 miles.</u>
<u>Finding the total miles:</u>
Total miles ran on Monday, Tuesday, and Wednesday = 39 + 24 + 4
= 67 miles
Step-by-step explanation:
C = 2πr = 53.38cm
r = C / 2π = 53.38cm / 2π = 53.38/ 6.283185307179586 = 8.4956cm
A = πr^2 = π × (8.4956cm^)2 = 226.4cm^2
Answer: 17 1/16
seventeen and one sixteenth
Step-by-step explanation:
Substitute x=2 and y=5 into equation
1/2x^3 + 3.4y
= 1/2(2)^3 + 3.4(5)
Solve in the order of BEDMAS (brackets, exponents, division, multiplication, addition, subtraction)
= 1/2(8) + 3.4(5)
= 1/16 + 3.4(5)
= 1/16 + 17
= 17 1/16
