Answer:
12 tiles
Step-by-step explanation:
First we need to find the area of the parallelogram, which can be found by the product of the two dimensions.
If the parallelogram has 6 cm and 10 cm, the area is 6 * 10 = 60 cm2
Then to find how many tiles are needed to fill the area of 720 cm2. we can do a rule of three:
1 tile -> 60 cm2
x tiles -> 720 cm2
x = 720 / 60 = 12 tiles
Answer:
Step-by-step explanation:
y = 10x + 50
x ---> no of weeks
y - intercept = 50
Choose all answers that are correct.
A.
5 + 8 = 13 and 13 × 35 = 455
B.
5 × 8 = 40 and 40 + 35 = 75
C.
5 × 35 = 175, 8 × 35 = 280, and 175 + 280 = 455
D.
45 × 15 = 675 and 675 ÷ 9 = 75
im so confused
a. 5 + 8 = 13 and 13 × 35 = 455 &
c. 5 × 35 = 175, 8 × 35 = 280, and 175 + 280 = 455
B. 14
C. 14 root 3
D. (7 root 3) /2
Answer:
B ) 14
Step-by-step explanation:
The altitude of an equilateral triangle:
h = s √3 / 2, where s is the length of one side of the triangle.
s √3 /2 = 7 √ 3 / : √3
s / 2 = 7
s = 7 * 2
s = 14 units
Answer:
m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z
or m = 2/3 - (π n_2)/18 for n_2 element Z
Step-by-step explanation:
Solve for m:
-cos(7 m + 2) sin(12 - 18 m) = 0
Multiply both sides by -1:
cos(7 m + 2) sin(12 - 18 m) = 0
Split into two equations:
cos(7 m + 2) = 0 or sin(12 - 18 m) = 0
Take the inverse cosine of both sides:
7 m + 2 = π n_1 + π/2 for n_1 element Z
or sin(12 - 18 m) = 0
Subtract 2 from both sides:
7 m = -2 + π/2 + π n_1 for n_1 element Z
or sin(12 - 18 m) = 0
Divide both sides by 7:
m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z
or sin(12 - 18 m) = 0
Take the inverse sine of both sides:
m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z
or 12 - 18 m = π n_2 for n_2 element Z
Subtract 12 from both sides:
m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z
or -18 m = π n_2 - 12 for n_2 element Z
Divide both sides by -18:
Answer: m = -2/7 + π/14 + (π n_1)/7 for n_1 element Z
or m = 2/3 - (π n_2)/18 for n_2 element Z

We will find the rate of Greg and Josh earning money that is the amount of money they receive per unit time (hour)
Since the trip is in 3 weeks,
Number of hours Josh worked = 3 weeks * (5 hours/week) = 15 hours
Number of hours Greg worked = 3 weeks * (8 hours/week) = 24 hours
Josh’s rate = $480/15 hrs = $32/hr
Greg’s rate = $480/24 hrs = $20/hr
Therefore
Josh makes $12/hr more than Greg
