Step-by-step explanation:
the area of garden is 970.08
Answer:
A
Step-by-step explanation:
Let the number of cards equal x.
Set up an equation for both companies, set equal to each other and solve for x.
0.10x + 12 = 0.12x + 10
Subtractb0.10x from both sides:
12 = 0.02x + 10
Subtract 10 from both sides:
2 = 0.02x
Divide both sides by 0.02:
X = 2/0.02
X = 100
100 cards would be the same price for both companies.
Note that sin 45 deg = opposite side / hypotenuse.
1 7sqrt(2)
Here, sin 45 deg = ----------- = --------------
sqrt(2) x
Cross multiplying, we get x = 7 [sqrt(2) ]^2 = 7(2) = 14 (answer)
Answer: b) 15.7
<u>Step-by-step explanation:</u>
Look at the z-table (below) to find 0.2500
Notice that the value is not on the table but is between 0.2486 and 0.2517 which are located on the z-table at 0.67 and 0.68
The given value is closer to 0.2486 so use 0.67 as the z-score.
Now, let's find the x-value using the formula:
