Answer: D
Step-by-step explanation:A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer
The balance is $145 but after one makes he minimum payment of $20, there is $125 left to pay. However interest is added before the next month’s bill is generated.
Remember that percent means out of 100. 1.5% means 1.5/100 = .015
To find 1.5% of 125 we multiply (.015)(125) = 1.875 But as this is money the interest is rounded to two decimal places and so is $1.88
We add this to 125 to get next month’s balance which is 125 + 1.88 = $126.88
Answer: (D) 9
<u>Step-by-step explanation:</u>
This is an isosceles triangle. Since the legs are congruent, then the base angles are congruent.
9x + 3 = 84
<u> - 3 </u> <u> -3 </u>
9x = 81
<u>÷9 </u> <u>÷9 </u>
x = 9
Standard form is Ax + By = C, or By = C - Ax.
Dividing both sides by B, we get y = C/B - (A/B)x
Here the y intercept is C/B, and the slope is -A/B.
Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. This line is thus y=9/4x-14, so C is correct. Multiplying by four, we get 4y=9x-56. Adding 56 and subtracting 4y, we see that 9x-4y=56, and multiplying by -1, we get 4y-9x=-56, so A is also correct. At this point, it is clear that B and D are incorrect, so A and C only are correct.
