Abcd is a parallelogram determine the length of BE
A)51 units
B)102 units
C)96 units
D) -11 units
Answer:
B) 102 units
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. This means ...
BE = ED
3 -9x = -8x +14
-11 = x . . . . . . . . . . . . add 9x -14
BE = 3 -9x = 3 -9(-11) = 3 +99

What is the surface area of the rectangular prism below?
Answer:
8*8 *2=64
8*19 *2=304
8*19*2=304
672units is your answer
The surface area of the rectangular prism below is 736 square units
Surface area of rectangular prismThe formula for calculating the surface area of the rectangular prism is expressed as:
A = 2(lw + wh + lh)
Given the following parameters
l = 8
w = 19
h = 8
Substitute
SA = 2(8(19) + 8(19) + 8(8))
SA = 2(152 + 152 +64)
SA = 2(304+ 64)
SA = 2(368)
SA = 736 square units
Hence the surface area of the rectangular prism below is 736 square units

A car drove 55 miles per hour for 8.2 hours and 75 miles per hour for 3.6 hours. How far did the car drive?
Answer:
Step-by-step explanation:
So at 38mph you are roughly traveling .6333 miles a minute. So 13 miles would take you roughly 8.2 minutes. How does one figure out this?
We know that there are 60minutes in an hour. We know you’re driving 38miles per hour. Dividing 38 by 60 gives you the miles per minute. Multiple that by how many miles you’re driving to get an estimate of the minutes it takes to drive those miles.

A rectangular garden is 16 feet wide. Its length is 8 feet more than twice the width. What is the area of the garden?
Answer:
640 ft²
Step-by-step explanation:
Hi there!
We're given:
Width = 16
Length = 2 x Width + 8
Solve for the length:
l = 2(16)+8
l=32+8
l=40
Therefore, the length of the garden is 40 ft.
To find the area, multiply the length and width:
A = lw
A = (16)(40)
A = 640 ft²

A child is chosen at random from the group.
a)
What is the probability that the chosen child is a girl?
Give your answer as a fraction.
b)
What is the probability that the chosen child is a left-handed girl?
Give your answer as a fraction.
Answer:
A. 2/5
B. 1/10
Step-by-step explanation:
First off we need to calculate the probability that the chosen child is a girl So to calculate this probability, we have to know the num. of girls which is seen in the table. There are a total of 8 girls.
Therefore the probability of a girl being chosen is equivalent to the number of girls/exact number of children = 8/20 = 2/5 simplified.
Now to find the probability that the chosen girl is left-handed.
The amount of left-handed girls there is only 2. therefore the probability of selecting a left-handed girl will be 2/20 = 1/10 simplified.

The reason how I got that is because to divide fractions, you have to turn them improper. Once you've done that, you then can multiply it by using the reciprocal of the second fraction. Once they are rearranged, multiply all the numerators by each other. do the same with the denominators and form a new fraction.

X = [?] cm
Enter a decimal rounded to the nearest tenth.
Answer:
x = 3.6
Step-by-step explanation:
If 2 chords of a circle intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
5x = 6 × 3 = 18 ( divide both sides by 5 )
x = 3.6
Using the intersecting chord theorem, the value of x is 3.6 cm
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We are given the parameters as;
the length of chords = x + 5 and 9 cm.
Using the intersecting chord theorem,
We know that If two chords of a circle intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is;
5x = 6 × 3
5x = 18
Now divide both sides by 5
x = 3.6

The selling price for houses in a neighborhood in West Richland, WA have an approximately normal distribution with a mean selling price of $275,000 and a standard deviation of $10,500. If 35 homes sell in this neighborhood, what is the probability that the average selling price of the 35 homes will be within $2000 of the true mean (that is, what is the probability the sample mean will be between $273,000 and $277,000)
The probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753
First, we need to find the z-score and this is expressed according to the formula;
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
x is the sample space
[tex]\mu[/tex] is the mean value
[tex]\sigma[/tex] is the standard deviation
Given the following parameters
Mean = $275,000
Standard deviation = $10,500
If the true mean is $273,000, then;
[tex]z=\dfrac{273,000-275000}{10,500} \\z = \frac{-2000}{10500}\\z= -0.1905[/tex]
If the true mean is $277,000
[tex]z=\dfrac{277,000-275000}{10,500} \\z = \frac{2000}{10500}\\z= 0.1905[/tex]
This means that the z-score is between -0.1095 and 0.1095
Pr( -0.1095 ≤ z ≤ 0.1095)
According to the z table, the probability that the average selling price of the 35 homes will be within $2000 of the true mean is 0.5753

)=19right parenthesis, equals, 19
f() = -5 when f(t) = -3t + 4 is equal to 19. The value of t is -5
The given function is f(t) = -3t + 4. To find the value of f() when it is equal to 19, we substitute 19 in place of f() in the equation.
f() = -3() + 4
Since the value of f() is not provided, we can solve for it by setting the equation equal to 19:
-3() + 4 = 19
To solve for f(), we isolate the variable on one side of the equation. First, we subtract 4 from both sides:
-3() = 19 - 4
-3() = 15
Then, we divide both sides of the equation by -3 to solve for :
/ -3 = 15 / -3
= -5
It's important to note that the notation f() represents the value of the function at a specific point, usually denoted by a specific value in the parentheses. In this case, we were given f() = 19, and our task was to find the corresponding value of . By solving the equation, we determined that = -5 in this scenario.
Therefore, f() = -5 when f(t) = -3t + 4 is equal to 19.
