Answer:
(A)
Step-by-step explanation:
Scott cycled for 10 minutes in first week, 15 minutes in second week,20 minutes in third week and 25 minutes in the fourth week which maintains a consistency in the line as there is consistent slope when drawn on a graph.
On, the other hand, harry cycled for 10 minutes in first week, 20 minutes in second, 40 minutes in third and 80 minutes in fourth week in which there is no consistency in the timings according to the weeks. Therefore, only, scott's method is linear as the number of minutes increased by an equal factor every week.
Answer:
C, 927
Step-by-step explanation:
Vince wrote the wrong number to represent the interest rate said by question.
First notice that we are finding the area of the trapezoid.
The area of a trapezoid is:
,
where h is the height, b₁ and b₂ being
the bases of the trapezoid.
But before we find the area we have to find the side length of the third side in the triangle. To find this, we need to use the Pythagorean Theorem.
When we solve this equation, we obtain 1.4387, which I will round to 1.4.
Now, we use the area formula. The side length of the bottom base is 1.4 + 7 = 8.4.
Plugging into the formula we get:
The answer to that is 2/7
X = measure of angle 1
y = measure of angle 2
z = measure of angle 3
w = measure of angle 4
Focus on the bottom triangle. The three angles add to 180 degrees
(angle 2) + (angle 3) + 116 = 180
y+z+116 = 180
y+z= 180-116
y+z= 64
Since we have the bottom triangle as isosceles, this means that y = z, so
y+z = 64
y+y = 64
2y = 64
y = 64/2
y = 32
making z = 32 as well
Similarly, angle 1 and angle 4 are 32 degrees because the 116 angle is opposite the top left-most angle, and congruent to this angle. In other words, the bottom triangle is a mirror image of the top triangle.
The figure is a rhombus because all four sides are the same length (as shown by the tickmarks)

Answer:
This figure is a rhombus
All four angles (angle 1 through angle 4) are the same measure. They are each 32 degrees
