Answer:
$1305.91
Step-by-step explanation:
To solve this, we can use the geometric sequence formula
[tex]\alpha _n=a_1*r^n^-^1[/tex]
If we plug in our values we get [tex]\alpha _n=200*1.085^2^3[/tex]

B(4,8)
Scalar Factor of 2: 2*B(4,8) -> B'(8,16)Scalar Factor of 1/2: 1/2*B(4,8) -> B'(2,4)Scalar Factor of 2: 4*B(4,8) -> B'(16,32)Scalar Factor of 2: 1/4*B(4,8) -> B'(1,2)if 2x+4 = (x²)²÷2 then what is x?
Answer:
Below.
Step-by-step explanation:
2x+4 = (x²)²÷2
2x + 4 = x^4/2
x^4 = 4x + 8
x^4 - 4x - 8 = 0
We can try trial an error to solve this
Looks like x = 2 fits it:
2^4 - 4(2) - 8
= 16 -8 -8 = 0
so x = 2 is one solution.
I can't find any other solution among other integers.
To find the other solutions you can draw a graph manually or by using software.
There will be either 1 or 3 more real solutions.
I used software to draw the graph and found one other solution:
x = -1.296
Solve the system of equations:
y= 2x - 2
y= x2 - x-6
O A. (-1,-5) and (4,2)
O B. (0, -2) and (2, 2)
O C. (-1,-4) and (4, 6)
D. (-2,0) and (3,0)
Answer:
C) (-1, -4) and (4, 6)
Step-by-step explanation:
[tex]\textsf{Equation 1}:y=2x-2[/tex]
[tex]\textsf{Equation 2}:y=x^2-x-6[/tex]
Substitute Equation 1 into Equation 2 and solve for x:
[tex]\implies 2x-2=x^2-x-6[/tex]
[tex]\implies x^2-3x-4=0[/tex]
Find two numbers that multiply to -4 and sum to -3: -4 and 1
Rewrite the middle term as the sum of these two numbers:
[tex]\implies x^2-4x+x-4=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies x(x-4)+1(x-4)=0[/tex]
Factor out the common term [tex](x-4)[/tex]:
[tex]\implies (x+1)(x-4)=0[/tex]
[tex]\implies (x+1)=0 \implies x=-1[/tex]
[tex]\implies (x-4)=0 \implies x=4[/tex]
Substitute the found values of x into Equation 1 and solve for y:
[tex]x=-1 \implies y=2(-1)-2=-4[/tex]
[tex]x=4 \implies y=2(4)-2=6[/tex]
Therefore, the solution to the system of equations is:
(-1, -4) and (4, 6)
The circle graph shows the rooms in a house and their percentages of the house's total area.
Rooms in a House

30%
The area of the kitchen is 300 square feet. How many square feet is the entire house? Record your answer in the box.
Answer:
2,000 square feet
Explanation:
If the kitchen is 300 square feet, we can divide that by the percentage(15%). We get the answer 20, which will be our conversion factor!
Now, we multiply this conversion factor by all the other percentages(without decimals)
5 x 20 = 100
20 x 20 = 400
30 x 20 = 600
15 x 20 = 300
30 x 20 = 600
Now we add up all of these factors and get the answer :D
100 + 400 + 600 + 300 + 600 = 2,000 square feet

Answer:
57.6% have allergies
42.4% have no allergies
Step-by-step explanation:
We only need to consider the students who speak two languages according to the question.
To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).
19/33 = 0.5757 = 57.6%
To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).
14/33 = 0.4242 = 42.4%
Check your work by adding the percentages to make sure they equal 100%
57.6 + 42.4 = 100

Draw the graphs of the lines below on the same grid to find the coordinates of the point of intersection. y + 5 = 2 x y = 7 − 2 x
Answer:
The point of intersection is (3,1)
Step-by-step explanation:
Manipulate these equations to achieve the form of y = mx + c
1) y + 5 = 2x
Y = 2x - 5
2) y = 7 - 2x
Y = -2x + 7
Point of intersection is (3,1) on the graph attached
To check algebraically:
2x - 5 = -2x + 7
4x = 12
X = 3
Substitute to get y
Y = 2x - 5
Y = 2 x 3 - 5
Y = 1
Therefore (3,1)
formula for area of triangle
Answer:
[tex]area \: of \: triangle \: = \frac{1}{2} b \times h[/tex]
The area of a triangle formula is A = 1/2 × b × h, where b is base and h is height.
What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Here,
The area of a triangle formula is 1/2× b × h, where b=base and h=height.
Example: Find the area of a triangle with base 12 units and height 3 units.
Now, area of a triangle = 1/2× 12 × 3
= 6 × 3
= 18 square units
Therefore, area of a triangle formula is A = 1/2 × b × h.

Thom needs 3/4 yard of brown fabric, 2/4 yard of blue fabric, and 3/4 yard of green fabric to make some costumes for a play.
Answer:
Step-by-step explanation:
Hey there!
I think that some of the content in your question is missing so I will be solving for how much yards of fabric is needed in total
Since all of the fractions have common denominators, we can comfortably add them together
3/4+3/4+2/4 is 8/4
8/4 can be simplied to 2
So the total amount of yards of fabric Thom needs in total is 2 yards

A. The median of the data is 55.
B. The interquartile range is 55.
C. Three fourths of the data is less than 65.
D. The median of the upper half of the data is 65.
Reset Selection
Answer:
B. The interquartile range is 55
Step-by-step explanation:
the interquartile range is Q3 minus Q1, you would get 15 ,not 55. So B is the answer to your question
Answer:
B. The interquartile range is 55.
Step-by-step explanation:
In this problem, I refer to the right part of the box as the median of the upper half and the left part of the box as the median of the lower half.
The median of the data is going to be the middle line of the box and whisker plot. The middle line lies on 55, so the median is 55.
Choice A is true
The interquartile range is the right end of the box subtracted from the left end of the box. The right end of the box is 65. The left end of the box is 40. Subtracting the left end from the right end, we get 25.
Choice B is false
3/4 of the data will be where we see the right end of the box. The right end of the box is at 65. So, 3/4 of the data is less than 65.
Note: 1/4 of the data is less than the left side of the box at 40. 1/2 of the data is less than the median of the box which is at 55.
Choice C is true
The median of the upper half is the right end which is 65.
Note: The median of the lower half is 40.
Choice D is true
