The equation can be written as:
4 + 5 / 2
Remember to follow PEMDAS.
4 + 5 / 2
4 + 2.5
6.5
Best of Luck!
Answer:
If you mean whats 4+5/2 the answer is 6.5 because PEMDAS says to Divide first . So 4+(5/2). 5/2 is 2.5. so 4+(2.5) which equals 6.5

Question 3 (1 point)
The Base of a prallelogram is is multiplied by 3 and the height is multiplied by 6. The area of the new paralellogram is multiplied by
Answer: The area of the new parallelogram is multiplied by 18
Step-by-step explanation: Let the base and the height of the original parallelogram be ' x '
Base of the parallelogram = x
Height of the parallelogram = x
Area of parallelogram = l × b = lb
= x × x = x²
∴ Area of the original parallelogram = x²
∴ The base is multiplied by 3 = 3x
The height is multiplied by 6 = 6x
∴ Area of new parallelogram = 3x × 6x = 18x²
∴ The area of the new parallelogram is multiplied by = 18x²/ x²
= 18

System of Equations: Solve for (x,y) given the system of linear equations "X 1 point
- y = 4" and "x + y = 4".
Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
x - y = 4x + y = 4Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).

Write and simplify an expression for the surface area of a rectangular prism with a height of h yards, a length of 2.6 yards, and a width of 3.5 yards. What is the surface area if the height is 4 yards?
Answer:
Surface Area= (18.2+12.2h) square yardsWhen h=4 yds, Surface Area=67 square yardsStep-by-step explanation:
Given the length(l), height(h) and width(w) of a rectangular prism.
Surface Area=2(lw+lh+wh)
For a rectangular prism with a height of h yards, a length of 2.6 yards, and a width of 3.5 yards.
Surface Area[tex]=2(2.6*3.5+2.6h+3.5h)[/tex]
[tex]=2(9.1+2.6h+3.5h)\\=18.2+5.2h+7h\\[/tex]
Surface Area= (18.2+12.2h) square yards
If the height, h=4 yards
Then the surface area of the rectangular prism
=18.2+12.2h
=18.2+12.2(4)
=18.2+48.8
=67 square yards
To approach the runway, a pilot of a small plane must begin a 5 degree descent starting from a height of 1407 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach?
Answer:
3.0 miles
Step-by-step explanation:
The tangent of the angle relates the opposite side (altitude) to the adjacent side (distance to runway):
tan(5°) = (altitude)/(distance to runway)
Then we have ...
distance to runway = (1407 ft)/(tan 5°) ≈ 16,082 ft
In miles, that is ...
distance to runway = (16082 ft)/(5280 ft/mi) = 3.0458 mi
The pilot is 3.0 miles from the runway at the start of his approach.

p(a): (a - 1), (a - 2) or (a + 4).
b) By the remainder theorem, state the remainder when p(a) is divided by the binomial
which are not its factors.
c) Use the factor from (a) to divide p(a) by long division.
d) Use the factor from (a) to divide p(a) by synthetic division. (your answer should
correspond with that from (c)).

Which statement(s) can be interpreted from the equation for a real estate value, V 228,000(1.03)' where V) represents the value of the real estate and t represents the time in years?
The equation is an exponential growth equation
The equation is an exponential decay equation
The equation is neither exponential decay nor exponential growth
$228.000 represents the initial cost of a real estate that appreciates 3% per year over the course of years
$228.000 represents the initial cost of a real estate that appreciates 30% per year over the course of years
$228.000 represents the initial cost of a real estate that depreciates 3% per year over the course of t years
$228.000 represents the initial cost of a real estate that depreciates 30% per year over the course of years
Answer:
The statements that are true for this equation are:
- The equation is an exponential growth equation.
- $228.000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
Step-by-step explanation:
We have the equation
[tex]V= 228,000(1.03)^t[/tex]
Where V: value of the real state and t: time in years.
As t is always positive in this case, and 1.03 is larger than 1, the value V will rise exponentially. The equation is an exponential growth equation.
The difference in value for each year is:
[tex]\dfrac{V_{t+1}}{V_t}=\dfrac{1.03^{t+1}}{1.03^t}=1.03^{t+1-t}=1.03\\\\\\V_{t+1}-V{t}=1.03V_t-V_t=0.03V_t[/tex]
We can conclude that the value increases each year 0.03 (3%) from the previous year value, starting from $228,000 in the year t=0.
$228.000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.

Lennox was curious if triangles \triangle ABE△ABEtriangle, A, B, E and \triangle DCE△DCEtriangle, D, C, E were similar, so she tried to map one figure onto the other using a reflection and a dilation. Lennox concluded: "It's not possible to map \triangle DCE△DCEtriangle, D, C, E onto \triangle ABE△ABEtriangle, A, B, E using a sequence of rigid transformations and dilations, so the triangles are not similar." What error did Lennox make in her conclusion?
Answer:
There is no error. This is a correct conclusion.
Step-by-step explanation:
If a sequence of rigid transformations
(translations, reflections, and rotations) and dilations can map △DCE onto △ABE, then the figures are similar.
Notice that both triangles are right triangles (at vertices B and C), with line AB and DC being the longer legs.
Therefore, if the triangles are similar, we should be able to map each pair of corresponding points onto each other with rigid transformations and dilations:
D should be mapped onto A.
C should be mapped onto B.
E should be mapped onto itself.
Lennox used a reflection across line BE and a dilation about E to get △DCE as close as possible to △ABE. But still, point D did not map onto point A.
So we can conclude that it's not possible to map △DCE onto △ABE using a sequence of rigid transformations and dilations.
Lennox concluded:
"It's not possible to map △DCE onto △ABE using a sequence of rigid transformations and dilations, so the triangles are not similar."
There is no error. This is a correct conclusion.
Answer:
there is no error

What is the median? I need this turned in aaa on but I don’t get it
Answer: 7,500 passengers
Step-by-step explanation: Let's put the numbers from least to greatest...
5,000, 6,000, (7,000, 8,000,) 9,000, 10,000
Since there is an even number of numbers we will have two medians for the time being...
7,000 + 8,000 = 15,000
15,000 ÷ 2 = 7,500
Therefore, the median is 7,500, there are 7,500 passengers in total.

There are 4,500 pounds of fruit in john’s store. 1200 pounds of the fruit is apples and half as much is mangoes. The weight of pears is three times the weight of mangoes. If the rest of the fruits are grapefruits, what is the total weight of grapefruits?
Answer:
the total weight of the grapefruits is 2100 pounds
Step-by-step explanation:
apples = a
mangoes = a/2
weight of pears=3*a/2
grapefruits=g
a+a/2=1200
3/2a=1200
1.5a=1200
a=800
800+400+1200+g=4500
g=2100
Therefore, the total weight of the grapefruits is 2100 pounds

are there?
Answer:
Step-by-step explanation:
I don't say u must have to mark my ans as brainliest but if it has really helped u plz don't forget ro thank me...
There are 41 white marbles in the bag.
Let's assume the number of green marbles is represented by "x". According to the given information, the number of white marbles is 3 less than 4 times the number of green marbles.
Number of white marbles = 4x - 3
The total number of marbles is given as 52, so we can write the equation:
Number of white marbles + Number of green marbles = Total number of marbles
(4x - 3) + x = 52
Combining like terms:
5x - 3 = 52
Adding 3 to both sides:
5x = 55
Dividing both sides by 5:
x = 11
Therefore, the number of green marbles is 11.
To find the number of white marbles:
Number of white marbles = 4x - 3
= 4 * 11 - 3
= 44 - 3
= 41
Hence, there are 41 white marbles.

You were shown into a great cavern. “Including yourself, there are 350 people in this cavern,” the genie said.
You looked around and said, “These don’t look like people, they look like mummies.”
“Yes they are mummies, little one. If you can’t solve my next puzzle, you may become one of them. You will join the mummies. Then you will all line up in a single line. I will go down the line and count 1, 2, 3, 4, 5, 6, and so on. Every even numbered person (or mummy) will step out of line. Whenever I reach the end of the line, I will go back to the beginning of the line and continue counting from wherever I left off. The even numbers will still step out of line. The last person or mummy left in line will get the buried treasure. You can stand anywhere you want, but choose wisely.”
The genie then shouted, “Line up,” as you worked furiously trying to figure out what position to be in. The mummies all began to shuffle into position. The genie turned to you and said, “Well, where do you wish to stand?”

Which value of k will make this relationship NOT a function? {(−7, 2), (−1, 0), (4, 8), (k, 0)}
Answer:
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
Step-by-step explanation:
Requirement to be a function:
For a relationship to be a function, all values of x must have only one corresponding value of y.
In this question:
For x = -7, y = 2
For x = -1, y = 0
For x = 4, y = 0
For x = k, y = 0
A value of x must not have more than 1 value of y.
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
