Answer:

x=16.75 y=4.5

Step-by-step explanation:

first turn the first trapezoid sideways so the side that says 8 matches with the side that says 10. This is the proportion. 8:10. The bottom of the first trapezoid says x+2. This matches with the side that says 15. Because the side that says 15 is on the bigger trapezoid, multiply by ten. Then multiply the other trapezoid by 8. We get an equation that looks like. 8x+16=150 Simplify and 8x=134 divide and we get x=16.75. Do the same for the side with y. 8y-24=50. 8y=36 y=4.5. There you have it.

Iodine-125 has a half-life of about 60 days. How many milligrams of a 1000 mg sample will remain after 240 days?

Tomtit [17]

240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to

$\dfrac{1000}{2^4}=\dfrac{125}2=62.5\,\mathrm{mg}$

after 240 days.

Dentify all the pairs of vertical angles in the figure. Pair#1: Pair#2

Brilliant_brown [7]

Ok so the only ones that we know for sure are 4 = 1, 6=8, 7=9 and you can’t really do all that much with 2,3,5 because it’s not as obvious

What is the fraction 18/24 reduced to its lowest terms?

WINSTONCH [101]

First, find the greatest common factor (GCF) of the numerator and denominator.

Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Common Factors: 1, 2, 3, 6
GCF: 6

Now, divide the numerator by 6 and the denominator by 6.

18 ÷ 6 = 3
24 ÷ 6 = 4

Set these as your new numerator and denominator.

$\frac{3}{4}$

The answer is (b).

Rectangular billboard 5 ft in height is 12 ft above the ground. Nearsighted cow with eye level at 4 ft above ground stands x ft

Inga [223]

In your question that ask to find the distance that the cow must stand fro the billboard in order to maximize the value of theta and based on my calculation and further formulation, I came up with an answer of the tan to the power of negative one of 11 over X.
