Answer:
The answer is 14 quarters and six dimes
Step-by-step explanation:
-.1(D+Q=20)
.10D+.25Q=4.10 -.1D-.1Q=-2
.1D+.25Q=4.10
------------------------------------------------------
.15Q=2.10/.15(both sides)
Q=14 which leaves you needing 60 more cents so 6 dimes
Answer:
The correct answer is "Circle 1 is a translation of 1 unit right and 7 units up from Circle 2, and a dilation of Circle 2 with a scale factor of 1.6"
Step-by-step explanation:
We can tell this because first they identify the movement properly. When going from (-3, 0) to (-2, 7), we move to the right one and up 7.
Also, we know there is a scale factor of 1.6, because when we look at the radius of each circle, we can divide and find that factor.
8x/5x = 1.6
B! Just graphed each answer on a calculator
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7
i hope this helps!
Answer:
B 84
Step-by-step explanation:
Angle COB = 96 (Angle CDB x2)
Lets split Quadrileteral ABOC into 2 equal parts.
Angle ABO = 90 (tangent segment of circle)
Angle AOB = 96/2 = 48
Angle OAB = 180 - 90 - 48 = 42
Angle A = Angle OAB x 2 = 42 x 2 = 84
Therefore Answer is B.
