$60 * 0.25 = 15
$55* 0.19 = 10.45
15-10.45 = $4.55
The difference is $4.55
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17

Answer:
0.21 or 21/100
Step-by-step explanation:
the chance of a female student getting a scholarship is 7/10. now that student already has a scholarship so now there are 9 students. the probability of the next female getting a scholarship is 6/9. and then the next is 5/8
7/10 x 6/9 x 5/8 = 21/100 or 0.21
Answer:
see below (I hope this helps!)
Step-by-step explanation:
First of all, we can clearly tell that a straightedge was used to create CD but that doesn't prove anything so we can eliminate the second and fourth options. Upon measuring the lengths of AC and CB, we see that they are equal so the answer is Yes; the compass was kept at the same width to create the arcs for points C and D. The reason why this is so important is because we know that AC = CB = BD = DA because the compass width is the same, so therefore, ACBD is a rhombus based on the definition of a rhombus. We know that the diagonals of a rhombus bisect each other and since CD and AB are diagonals, we know that CD bisects AB.
