0.875
Step-by-step explanation:
they're proportional.
Answer: 2,000 ÷ 50
Step-by-step explanation:
From the question, we are informed that John needs to write 2,146 online math questions in 45 weeks and that he is estimating how many questions he should write each week to meet the deadline.
The compatible numbers that provide a better estimate for the number of question he should write each week, is 2,000 ÷ 50. This is because rounding up of 2146 to the nearest thousand gives 2000. The number beside the thousand place is 2 and sinces it's not up to 5, the number becomes 2000. Likewise 45 to the nearest ten gives 50 since the number beside the ten is 5, therefore 1 will be added to 4 which becomes 5 and the number in the unit place is changed to 0, this makes the number become 50.
Therefore, the answer is 2000 ÷ 50.
Answer:
Each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
Step-by-step explanation:
Make a sketch and find an isosceles triangle formed by the diagonal, shorter base and the lateral side of the trapezoid.
Thus you have the lateral sides of the trapezoid congruent to the shorter base.
Your trapezoid then has the sides of 5:3:3:3 units.
In total, there are 5 + 3 + 3 + 3 = 14 units.
Hence, each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.

We have been given 4 points 
. We are asked yo plot these points on coordinate plane and find the area of the figure.
Upon plotting our given points, we will get a rectangle as shown in the attached file.
We can see that the width is 5 units that is difference between y-coordinates of point 
.
We can see that the length of rectangle is 6 units that is difference between x-coordinates of point 
.
We know that area of rectangle is length times width.
Therefore, the area of the figure would be 30 square units.
Answer: You apply the trigonometric ratios of Sine, Cosine and Tangent.
Step-by-step explanation: In a question such as this one of the angles must be given, which is labeled the reference angle. We already know one angle is 90 degrees in a right angled triangle, so the other two angles whatever their size is, must both add up to 90, which means they are both acute angles. If one side is given, for instance 10 units, and one of the two acute angles is given, for example 30 degrees, then the line facing the reference angle (30 degrees) would be the OPPOSITE. The line that lies between the angles 30 and 90 would be the ADJACENT while the third side which is the longest would be the HYPOTENUSE.
So if for instance, the opposite line is 10 units, and you are required to calculate the other line, the adjacent, AS LONG AS YOU HAVE BEEN GIVEN A REFERENCE ANGLE, you can simply calculate as follows;
TanX = opposite/adjacent (and that becomes)
Tan 30 = 10/adj
Adj = 10/Tan 30
Adj = 10/0.5774
Adj = 17.32
**Note that the use of angle 30 was just for the sake of explanation. Your reference angle whatever it is, would be provided by your examiner**
