To obtain an overall average of 86%, a score of 96 is required on her 4th test.
Let the required score on her fourth test = t
The required average = 86%
Initial scores : 80% + 83.5% + 84.5%
Average = ΣX/ (fx)
fx = total score obtainable = 4 × 100 = 400
ΣX = sum of scores
Average = 86%
0.86 = ((80 + 83.5 + 84.5 + t) / 400)
86 = (248 + t) / 400
400 × 0.86 = 248 + t
344 = 248 + t
344 - 248 = t
96 = t
In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

- -- There are 260.714 weeks total in 5 years.
But you can round by doing this:
52*5=260
This is because you have 52 weeks in a year and 55 years so you multiply.
Answer:
m<P = 30°
Step-by-step explanation:
∆PQR has two equal sides. An isosceles ∆ has two equal sides and the angles opposite the two equal sides are congruent to each other.
Thus, we can conclude that ∆PQR is an isosceles ∆ with two equal base angles, <P and <Q.
Since m<Q = 75°, therefore, m<R = 75°.
m<P = 180 - (75 + 75) (sum of ∆)
m<P = 30°
Answer:
The answer is 3,019.92 cubic millimeter
Step-by-step explanation:
take 375 plus 375 to get 750
then 3769.91 - 750 to get the 3,019.92
