The perimeters of the squares are 36 units, 48 units and 60 units respectively.
What is a perimeter?The perimeter of a polygon or a thing is the sum of the sides lengths of the respective figures.
Given is a figure in which 3 squares are joined by bases and making a right triangle,
The sides are given by, a = 9, b = 12, and c = 15
we know that, perimeter of a square = 4 × sides
Perimeter of square a = 4 × 9 = 36 units
Perimeter of square b = 4 × 12 = 48 units
Perimeter of square c = 4 × 15 = 60 units
Hence, The perimeters of the squares are 36 units, 48 units and 60 units respectively.

Answer:
[tex]A = 19.4[/tex]
[tex]B = 77.6[/tex]
[tex]C =83[/tex]
Step-by-step explanation:
Given
By interpreting each line, we have:
[tex]B = 4A[/tex]
[tex]C = 5A -14[/tex]
Required
Solve for A, B and C
In a triangle,
[tex]A + B + C = 180[/tex]
Substitute expressions for B and C
[tex]A + 4A + 5A - 14 = 180[/tex]
[tex]A + 4A + 5A = 180+14[/tex]
[tex]10A = 194[/tex]
Solve for A
[tex]A = 194/10[/tex]
[tex]A = 19.4[/tex]
[tex]B = 4A[/tex]
[tex]B = 4 * 19.4[/tex]

Suppose the purchase price of a dining room set is $950. If the sales tax is $47.50, what is the sales tax rate?
Answer:
5%
Step-by-step explanation:
this question is really asking what percent of 950 is 47.5?
is/of = %/100
47.5 is the 'is'
950 is the 'of'
'r' is the 'what percent'
47.5/950 = r/100
cross-multiply to get:
950r = 4750
r = 5
Answer:
5%
Step-by-step explanation:
Price x sales tax rate = sales tax
950 x sales tax rate =47.50
sales tax rate =47.50/950
sales tax rate = .05 or 5%

Samuel made a list of his test scores: 88, 100, 92, 80, 85, 94, and 90. What is the lowest test score he can get on his next test to have mean score of 90?
Answer:
he needs to get a 91 to have a mean score of 90
Step-by-step explanation:
add up all the known scores to get 629
let 's' = lowest test score
(629 + s) ÷ 8 = 90 [we divide by 8 because there are 7 known and 1 unknown score)
cross-multiply to get:
629 + s = 720
s = 720-629
s = 91

Write the following series in sigma notation. 8+18+28+38
Answer:
[tex]\Sigma\left {n} \atop {1}} \right. (5n^2+3n)[/tex]
Step-by-step explanation:
Given the series 8 + 18 + 28 + 38
First, we need to find the sum of the nth term of the sequence as shown
Sn = n/2[2a+(n-1)d]
n is the number of terms
a is the first term = 8
d is the common difference = 18-8 = 28-18 = 10
Substitute
Sn = n/2 [2(8)+(n-1)*10]
Sn = n/2 [16+10n-10]
Sn = n/2[10n+6]
Sn = 2n/2(5n+3)
Sn = n(5n+3)
Sn = 5n²+3n
In Sigma form;
[tex]\Sigma\left {n} \atop {1}} \right. (5n^2+3n)[/tex]
What is the volume of the rectangular prism?
3 cm
8 cm
2 cm
cm3
Answer:
48 cm^3
Step-by-step explanation:
Since there is no image, I’m just going to assume that these three measurement are the length, width, and height of the rectangular prism:
The formula for the volume of a rectangular prism is length x width x height.
Use formula with given dimensions:
3 x 8 x 2 = 48
Volume is measured in cubic centimeters
(cm in this case)
Therefore, the volume of the rectangular prism is 48 cm^3

Find the first four terms of the sequence given by the following
9514 1404 393
Answer:
59, 56, 53, 50
Step-by-step explanation:
Use n = 1 through 4 and evaluate.
a1 = 59 -3(0) = 59
a2 = 59 -3(1) = 56
a3 = 59 -3(2) = 53
a4 = 59 -3(3) = 50
The first four terms are 59, 56, 53, 50.
thomas is sketching the graph of a quadratic function. he is asking his friends about how many x-intercepts his function can have. here is the feedback from his friends.
Allison says the graph can have 1 x-intercepts
Richard says the graph can have no x-intercepts
Linda says the graph must have two x-intercepts
Hope says the graph can have, at most 1 x-intercepts
How many of Tom's friends are right and why?
A: 0
B: 1; Linda is right because a quadratic graph has exactly two x-intercepts
C: 2; Allison, Richard, and Hope are right because the graph can have 0,1, or 2 x-intercepts.
D: 4; They're all right because the graph can have varying number of x-intercepts
Answer:
C: 2; Allison, Richard, and Hope are right because the graph can have 0,1, or 2 x-intercepts.
Allison, Richard, and Hope are right because the graph can have 0, 1, or 2 x-intercepts.
The correct option is C.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Allison is correct because a quadratic function can have one x-intercept if its vertex is on the x-axis.
Richard is correct because a quadratic function can have no x-intercepts if its vertex is above the x-axis.
Linda is incorrect because a quadratic function can have two x-intercepts, but it is not required to have them. It is possible for the vertex of a quadratic function to be on the x-axis, in which case it would have one x-intercept.
Hope is correct because a quadratic function can have at most one x-intercept if its vertex is below the x-axis.
Therefore,
Two of Thomas's friends (Allison and Hope) are correct in their statements.

If a1 = 8 and an
An-1 + 2 then find the value of a4.
9514 1404 393
Answer:
a4 = 14
Step-by-step explanation:
Use the recursive definition repeatedly.
a1 = 8
a2 = a1 +2 = 8 +2 = 10
a3 = 10 +2 = 12
a4 = 12 +2 = 14
_____
The recursive definition tells you the terms of the sequence have a common difference of 2. The explicit formula for a term of the sequence can be written as ...
an = 8 + 2(n-1)
Then a4 is ...
a4 = 8 +2(4 -1) = 8+6
a4 = 14
