Answer:
15/4 in or 3.75 in
Step-by-step explanation:
Find your equations:
L = 4w + 9 in
A = L*w = 90 in^2
Substitute L:
L*w = 90 in^2 <-- L = 4w + 9
(4w + 9in)w = 90 in^2
4w^2 in^2 + 9w in = 90in^2
Solve Simultaneously:
w = -6 in, 15/4 in
Width is positive so it is 15/4 in or 3.75 in.
Double check:
(4w + 9in)w = 90 in^2
(4*3.75in + 9in)(3.75in) = 90 in^2

Liam had 75% more magnets than John at first. Liam gave away 200% as many magnets as John. John was left with 25% of the magnets he had at first. What fraction of Liam's magnets did he have in the end?
Answer: 6/4x
Then John ended up with v/4 magnets and gave away (3/4)x
Liam gave away 2 ( 3/4)x = 6/4x magnets and was left with x/4 magnets
Notice that they have the same number now so John has 100% of Liam's magnets

Stephen spent $12.35 at a food truck. He bought 3 burgers for $1.25 each and 4 corndogs.
How much did Stephen pay for each corndog?
$2.86
$8.60
$2.77
$2.15
Answer:
The 3rd one 2.15
Step-by-step explanation:
12.35 in whole
1.25 x 3 = 3.75
12.35-3.75= 8.60
[tex]\sqrt[4]{8.60}[/tex] = 2.15
pls give brainlist <33
Answer:
$2.15
Step-by-step explanation:
Start off by multiplying $1.25 by 3 to find out how much the burgers are all together. This would be $3.75 for all three of the burgers. Then subtract $3.75 from the total amount spent ($12.35). This would give you $8.60. To find how much he spend on each corndog, you do $8.60 divided by 4. This would give you the answer of $2.15.
Which statements are true about the graph of the function f(x) = x2 – 8x + 5? Select three options.
The function in vertex form is f(x) = (x – 4)2 – 11.
The vertex of the function is (–8, 5).
The axis of symmetry is x = 5.
The y-intercept of the function is (0, 5).
The function crosses the x-axis twice.
The equation is f(x) = x² – 8x + 5. Then the y-intercept is at (0, 5) and the function crosses the x-axis twice. Then the correct options are A, D, and E.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic equation is given below.
f(x) = x² – 8x + 5
Convert the equation into vertex form, then the equation will be
f(x) = x² – 8x + 5
f(x) = x² – 8x + 16 – 16 + 5
f(x) = (x – 4)² – 16 + 5
f(x) = (x – 4)² – 11
The graph of the function is given below.
From the graph, the y-intercept is at (0, 5) and the function crosses the x-axis twice.
Then the correct options are A, D, and E.

Taylor bought some jeans on sale. The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans. Find the amount of money Taylor spent,
Answer:
30
Step-by-step explanation:
Let the amount of money Taylor spent = x
The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.
Hence
1/5 × x = 6 jeans
x/5 = 6 jeans
Cross Multiply
x = 5 × 6 jeans
x = 30
The amount of money Taylor spent = 30
Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100
Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Mrs.Zomoro is 36 years old and her son is 4.When will the mother be thrice as o old as her son?
Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.
