URGENT!!LAST QUESTION!!!! PLS JUST TAKE A LOOK! EASY BUT I AM DUMB!!!!!! WILL GIVE BRANLIEST!! The following two triangles are similar. Find the missing side length represented by x. A) 25.2 in B) 26.25 in C) 24 in
Answer:
[tex]x = 26.25[/tex] inches
Step-by-step explanation:
Since we know the triangles are similar, we can simply set up ratios to find the length of side length 'x'.
[tex]\frac{15.75}{x} = \frac{9}{15}[/tex]
Cross multiply:
[tex]236.25 = 9x[/tex]
Divide both sides by '9' to solve for 'x':
[tex]\frac{236.25}{9} = \frac{9x}{9}[/tex]
[tex]x = 26.25[/tex]
Therefore, side length 'x' equals 26.25 in.
A sports club charges an initiation fee and a monthly fee. At the end of the 5 months, a member had paid a total of $450. At the end of the 10 months, she had paid a total of $500.
a) Write a linear system to model the situation
b) Solve the linear system by substitution to solve the related problem: What are the initiation fee and the monthly fee?
Answer:Initiation fee is $400 while monthly fee is $10
Step-by-step explanation:
Let the initial fee be x which is fixed while the monthly fee be y
At the end of 5 months, 450 was paid
This means that;
x + 5y = 450 ••••••••(i)
At the end of 10 months, $500 was paid
Mathematically, this means that;
x + 10y = 500•••••••••••(ii)
now we solve both equations simultaneously to get the value of x and y
our equation ii can be rewritten as;
x + 5y + 5y = 500
we can now insert equation i directly into this
450 + 5y = 500
5y = 500-450
5y = 50
y = 50/5
y = $10
From x + 5y = 450
let’s insert the calculated value of y
x + 5(10) = 450
x + 50 = 450
x = 450-50
x = $400
f(x) = (x + 3)(x + 5).

Find the volume of the rectangular prism. Express your answer as a simplified mixed number.
Answer:
414 9/16 m³
[tex]414\frac{9}{16}m^{3}[/tex]
Step-by-step explanation:
The volume of a Rectangular prism is calculated as Length × Width × Height
From the attached diagram,we can see that
The length = 8 3/8 m
The width = 6 m
The height =8 1/4 m
Converting the mixed fraction to improper fraction in other to simplify it better
The length = 67/8 m
The height = 33/4 m
The volume of the rectangular prism =
67/8 m × 6m × 33/4m
= (13266/32)m³
= 6633/16 m³
= 414 9/16 m³
= [tex]414\frac{9}{16}m^{3}[/tex]

solve for d
Answer:
d =±2sqrt(7) i
Step-by-step explanation:
d^2 = -28
Take the square root of each side
sqrt(d^2) = ±sqrt(-28)
d = ±sqrt(-28)
d = ±sqrt(-1)sqrt(28)
We know that sqrt(-1) = i

d =±i 2sqrt(7)
d =±2sqrt(7) i
Mr. Smith plans to serve 200 hamburgers at the company picnic. How many packages of hamburger buns will he need if buns come in packages of 12? How many packages will he need if buns come in packages of 16?
Answer:
34 packages
25 packages
Step-by-step explanation:
He needs a pair of buns for each hamburger.
He needs 200 hamburger. That means that he needs 400 buns for his picnic.
If buns come in a package of 12, the number of packages he needs is:
400 / 12 = 33.33 packages
Because packages come in whole numbers, we have to round up.
That means he needs 34 packages.
If buns come in a package of 16, the number of packages he needs is:
400 / 16 = 25 packages

Saturn is 8.867 × 108 miles away from the Sun. Uranus is 1.787 × 109 miles away from the Sun. Approximately how many times farther is Uranus from the Sun than Saturn is?
A. 0.2 times
Answer:
0.2 times
Step-by-step explanation:
Saturn: 8.867 × 108 = 957.636
Uranus: 1.787 × 109 = 194.783
You take (Uranus: 194.783)
& you divide it by (Saturn: 957.636)
You should get a funky number like 0.203399830415732 but since they said approximately you only need to use the first 2 (don't forget to round)
That would make Uranus 0.2 times as far from the sun
Bernard is two years older than his sister Therese and four years younger than his sister
Josephine. The product of his sisters' ages is the age of his mother, 40.
A. If x is Bernard's age, write his two sisters' ages in terms of x.
Answer:
B. Write Bernard's mother's age in terms in terms of x and solve this quadratic equation.
Answer:
C. What is Bernard's age?
Answer:
Please show working out
Firstly Bernard = x
A) lets focus on Therese first. Bernard id two years older than her so for Therese’s equation in terms of x it would be x+2. Now for Josephine Bernard is 4 years younger than HER so it would be 4-x.
B) The mother is the PRODUCT of the sisters’ ages so (multiplication)
It would be like this: (x+2)(4-x)= 40 This is all in terms of x.
Solving for the equation (using distributive property) we get:
4x-x+8-2x=40
(Reorganize to group like terms, remember to go in order from the numeral numbers with variables, to variables only then numbers only): 4x-2x-x+8=40 (now combine like terms and simplify): x+8=40 this is his mom’s age in terms of x
C) HERE we can solve for x:
Isolating x to get the answer we move the 8 to the other side of the equation and it becomes a negative 8 so:
x=40-8
x=32
Therefore Bernard is 32 years old.

Recall the shipping box scenario from the Introduction. As an employee of a sporting goods company, you need to order shipping boxes for bike helmets. Each helmet is packaged in a box that is n inches wide, n inches long, and 8 inches tall. The shipping box you order should accommodate the boxed helmets along with some packing material that will take up an extra 2 inches of space along the width and 4 inches of space along the length. The height of the shipping box should be the same as the helmet box. The volume of the shipping box needs to be 1,144 cubic inches. The equation that models the volume of the shipping box is 8(n + 2)(n + 4) = 1,144.
Answer:
The dimensions of the helmet box are as follows
Width is 9 inches
Length is 9 inches
Height is 8 inches
The dimensions of the shipping box ordered are as follows;
Width is 11 inches
Length is 13 inches
Height is 8 inches
Step-by-step explanation:
8(n + 2)(n + 4) = 1144
8·n² + 48·n + 64 = 1144
8·n² + 48·n - 1080 = 0
8×(n - 9)×(n + 15) = 0
∴ n = 9 or -15 inches
The dimensions of the helmet box are as follows
Width = 9 in.
Length = 9 in.
Height = 8 in.
The dimensions of the shipping box ordered are as follows;
Width = 9 + 2 = 11 in.
Length = 9 + 4 = 13 in.
Height = 8 in.

Answer:
f = 6, g = 8
Step-by-step explanation:
The area of Δ ADE = 60 - 48 = 12 cm²
Thus
[tex]\frac{1}{2}[/tex] AD × 4 = 12, that is
2AD = 12 ( divide both sides by 2 )
AD = 6 = f
The area of ABCD = 48 cm² , thus
fg = 48 , that is
6g = 48 ( divide both sides by 6 )
g = 8
Thus f = 6 and g = 8

. Suppose you plan to make a box that will hold exactly 40 one-inch cubes. Give the dimensions (ex: 1in x 1in x 40in) of 3 possible boxes you can create to hold all cubes.
Answer:
The dimensions of the three possible boxes are;
Box 1: 2 inches length by 4 inches width by 5 inches height
Box 2: 2 inches length by 2 inches width by 10 inches height
Box 3: 8 inches length by 1 inch width by 5 inches height
Step-by-step explanation:
The dimensions of the required box = 40 in³
Therefore, a box that will hold all the cubes will have a dimension given as follows;
Length, l × Width, w × Height, h = 40 in.³
We therefore, look for possible dimensions of l, w, h, however to make is faster, we note that l × w = base area, BA, hence we look for the factors 40 thus;
BA × h ≡ l × w × h
8 × 5 = 40 ≡ 2 × 4 × 5 = 40
4 × 10 = 40 ≡ 2 × 2 × 10 = 40
8 × 5 = 40 ≡ 8 × 1 × 5 = 40
Hence we have our three possible boxes as follows;
Box 1: Length = 2 inches, width = 4 inches and height = 5 inches
Box 2: Length = 2 inches, width = 2 inches and height = 10 inches
Box 3: Length = 8 inches, width = 1 inches and height = 5 inches.

Answer:
4096
Step-by-step explanation:
Lets start by applying a basic exponent rule. (a*b)^n is equal to a^n * b^n
Therefore,
((9(3/16)^-2)^3/2 = 9^3/2 * ((3/16)^-2)^3/2
Now lets focus on ((3/16)^-2)^3/2
(3/16)^-2 = 1/(3/16)^2 = (16^2/3^2)^3/2.
We can quickly eliminate the fractional exponent by plugging it into the numerator and the denominator and we get, 16^3/3^3 = 4096/27
So now we have, 9^3/2 * 4096/27
We can easily compute 9^3/2, which is (sqrt(9))^3, which is equal to 27.
Therefore, you have, 27*4096/27. The 27 cancels to give us a final answer of 4096
