The correct option is b. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
<h3>How to explain the information?</h3>
The figure is a parallelogram and one diagonal measure 28 units.
In this case, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
Therefore, the correct option is B.

Answer:
Step-by-step explanation:
The standard form is called the scientific notation expressed generally as;
A is an integer between 1 and 10
n is ant integer or fraction
Given the decimal value 98.704, we ill shift the decimal point to the back once to have;
98.704 =
<u>Note the when the decimal point is shifted backwards the value of n is always positive</u>. Hence the expansion in power of 10 is
Answer:
40 km on the highway
30 km on the city roads
Step-by-step explanation:
Let x = highway
Let y = city road
The time formula: time = distance / speed.
1) Since we do not know the distance travelled on the highway and city roads but we do know the total time taken, we can say x + y = 70. Set the distances x and y and all equated to 2 hours, since we do not know them, nor do we know the time. This is called a system of equations.
x + y = 70
x/80 + y/20 = 2
2) Solve the system of equations using substitution.
x = 70 - y
---------------
70 - y/80 + y/20 = 2
70 + 3y/80 = 2
y = 30
---------------------------------
x + 30 = 70
x = 70 - 30
x = 40
Therefore, the delivery truck travelled 40 km on the highway and 30 km on the city roads.
In the study of probability, you find the chances of an event to happen likely out of the total number of possibilities. Thus, probabilities are always presented as part of a whole: in terms of fractions or percentages.
In this problem, the denominator for the probability would be the total number of possibilities. In combination probability, we use the equation: n!/r!(n-r)!, where 'r' is the number of like things out of 'n' objects. So, the denominator would be 5 drawn chips out of a total of 14 chips. So,
denominator = 14!/5!(14-5)! = 2,002 ways
For the numerator, we multiply the combination for 3 out of 10 chips and 2 out of 4 chips.
Numerator = 10!/3!(10-3)! × 4!/2!(4-2)!
Numerator = 720 ways
Thus, the probability is
Probability = 720/2002 = 360/1001 or 35.96%
Answer:
111 square units.
Step-by-step explanation:
Find the overall rectangle's area. 8*15 = 120.
Find the missing triangle's area (which is half of a rectangle with hthe same dimensions). The dimensions (15 - 9 = 6 and 8 - 5 = 3). 6*3 = 18, divide by half to find the triangle's area. The missing triangle's area is 9 square units.
Subtract the missing triangle from the overal rectangle. 120 - 9 = 111 square units.
