9514 1404 393
Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
Answer: B
Step-by-step explanation:
The ratio of the areas of similar figures is the square of the scale factor.
- Scale factor = image/preimage = 48/12 = 4.
So, the ratio of the areas is 16, and thus the area of DEF is (16)(90)=1440
By definition, when we say circumference, this is the measure or the distance around the circle. To find the circumference of a circle we use this formula. C = π x the diameter of the circle or C = 2πr .
Given that the radius is x/2 miles, let us plug in the values.
So C = 2(3.14)(x/2)
C = 6.28 (x/2)
C= 6.28x/2
C = 3.14x
So the circumference of the given circle above would be 3.14x miles. Hope this answer helps.
