Answer:
129° and 37°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
∠ 1 is an exterior angle, thus
∠ 1 = 62° + 67° = 129°
(b)
∠ 1 + 115° = 152° ( subtract 115° from both sides )
∠ 1 = 37°
The answer would be C) 24,500.
y = 70000(0.5)^(x/4), where x equals the number of hours.
(Attached is an image with the equation properly formatted.)
The function for exponential decay is <em>y = a(1 - b)^x</em>, where y is the final amount, a is the starting amount, b is the decay percentage in decimal form.
So, just fill in the values.
y = 70000(1 - 0.5)^x
y = 70000(0.5)^x
In this case however, x represents the number of sets of four hours, so we should probably divide x by 4 to make x represent the number of hours.
y = 70000(0.5)^(x-4)
The two equations are: 3x + 2y = 36.50 (I)2x + 5y = 50 (II)Eliminating x from the two equations by subtraction:first we multiply equation I by 2 and equation II by 36x + 4y = 736x + 15y = 150Subtracting the two,-11y = -77y = 7He earns $7 at the coffee cartSubstituting y into equation I,3x + 14 = 36.5x = $7.50Therefore, he earns a greater wage of $7.50 at the library, the answer is C

A circle's radius is 0.3 yd. What is its area?
![\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}](https://tex.z-dn.net/?f=%5Clarge%5Cblue%5Ctextsf%7B%5Ctextbf%7B%5Cunderline%7B%5Cunderline%7BAnswer%20and%20how%20to%20solve%3A-%7D%7D%7D%7D)
Formula for Area of a Circle:-
⇒ A=πr²
<u>Where</u>
- A = area
- π = pi, 3.14
- r = radius, 0.3 yd
Substitute:-
A=π(0.3)²
On simplification,
A=0.09π
On further simplification,
⇒ A=0.283 yd²
<h3>Good luck.</h3>
