Given:
Consider a rhombus.
To find:
Which of the given statements about a rhombus is not true?
Solution:
Properties of a Rhombus:
1. It is a quadrilateral which is a special case of a parallelogram.
2. It has four equal sides.
3. It has two sets of parallel sides.
4. Opposite angles are equal.
5. Diagonals are perpendicular bisectors.
Since a rhombus doesn't has four right angles, therefore the last statement in the given options is not true about the rhombus.
Hence, the correct option is D.
Using the exponential growth function for the U. S. population from 1970 through 2003:

with the U.S. population being 205.1 million in 1970,
when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.
2018
D.
2038
Answer:
Step-by-step explanation:
Using the exponential growth function for the U. S. population from 1970 through 2003:
A = 205.1e^0.011t
with the U.S. population being 205.1 million in 1970, when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.
2018
D.
2038
We have the expression
A = 205.1e^0.011t
We are asked to find when would the U. S. population reach 350 million
A = 350
350 = 205.1e^0.011t
We divide both sides by 205.1
Divide both sides by 205.1
350/205.1 = 205.1e^0.011t/205.1
1.7064846416 = e^0.011t
We take the log of both sides
log 1.7064846416 = log e^0.011t
log 1.7064846416 = t log 0.011
t = log 1.7064846416/ log 0.011
t = 0.1185057826

A store has clearance items that have been marked down by 55%. They are having a sale advertising an additional 25% off clearance items. What % of the original price do you end up paying
Answer: 33.75%
Step-by-step explanation:
The items were marked down by 55% from their original price.
This means that the new price is:
= 1 - Percentage marked down
= 1 - 55%
= 45% of the original.
From this 45%, additional percentage of 25% is removed from this amount. The amount left will be:
= 45% * ( 1 - 25%)
= 33.75%

Jonathan has 25 coins in his pockets and they are all either nickels or quarters. If he has a total of
$3.25, how many of the coins are nickels and how many are quarters. Give me two equations and the answer in nickels and quarters
Answer:
The answer is 10 quarters and 15 nickels
Step-by-step explanation:
Lets say x equals the number of quarters and y quals the number of nickels. Since there is a total of 25 coins that means that x+y=25. But, the quarter costs 0.25, and the nickel costs 0.05. That means that we have to multiply the number of each coin with their cost. Which leads us to: (x*0.25)+(y*0.05)=3.25. By solving these two equations you'll see that x=10 and y=15.

The seniors and juniors at Sweet Valley High School are going on a trip to Busch
Gardens. The seniors filled 12 vans and 12 buses with 564 total students. The juniors
filled 6 vans and 13 buses with 492 students. How many students were in each van? In
each bus?
Solve the system of equations
Answer:
buses can hold 30 and vans can hold 17.
Step-by-step explanation:
Let the amount a van can hold be v and the amount a bus can hold be b.
12 vans and 12 buses totals 564: 12v + 12b = 564 (equation 1)
6 vans and 13 buses totals 492: 6v + 13b = 492 (equation 2)
Subtract 2 times equation 2 from equation1, we get 14b = 420.
Thus, b = 30.
Since 12v + 12b = 564, plugging in b=30, 12v + (12)(30) = 564, so v = 17.
The number of students filled in the van is 17, and number of students filled in the bus is 30.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the total number of students in van is x, and the number of students in the bus is y
Now for the first scenario we can frame a linear equation in two variables such as:
12x + 12y = 564 or
x + y = 47 ....(1) (divide by 12 on both sides)
For the second scenario the linear equation in two variables becomes:
6x + 13y = 492 ....(2)
From the equation (1) take the value of x and plug in the equation (2), we get:
6(47-y) + 13y = 492
282 - 6y +13y = 492
7y = 492-282 (subtract 282 from both sides)
7y = 210
y = 30
Put this value in the equation (1), we get:
x + 30 = 47
x = 17 (subtract by 30 from both sides)
Thus, the number of students filled in the van is 17, and number of students filled in the bus is 30.

The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. (a) What is the median value of each data set? (b) Compare the median values of the data sets. What does this comparison tell you in terms of the situation the data represent? For 100 point pls
Answer:
a brand x = 13 (median ) brand y = 16 median
Answer:
A) Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore: Median value for Brand X = 13 and Median value for Brand Y = 16. B) Brand Y has a higher median value (16) than Brand X (13). This implies that brand Y has a battery life that last longer than brand X.

The diagonal of a rectangle frame is 8 inches and the width of the frame is 6 inches. What is the length of this frame in inches?
Answer:
5.3 inches
Step-by-step explanation:
The diagonal of a rectangle frame is 8 inches and the width of the frame is 6 inches. What is the length of this frame in inches?
Diagonal² = Length² + Width²
Length = √Diagonal² - Width
= √8² - 6²
= √64 - 36
= √(28)
Length = 5.2915026221 inches
Approximately = 5.3 Inches

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Dwayne watched a movie that began at 4:38 p.m. The movie finished at 6:22 p.m.
Now, The length of movie watched by Dwayne is,
⇒ 6 : 22 - 4 : 38
⇒ 1 : 84
⇒ 2 : 24
Hence, The movie would be 2 hours 24 minutes long.
