The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch Isla is building a model of the statue the model will be one hundreth times as the actual model how tall will the model be
Answer: The actual model is 3.055 feet tall.
Step-by-step explanation:
Given: The statue of liberty is 305.5 feet tall from the foundation of it pedestal to the top of its torch .
The height of the model of the statue = [tex]\dfrac{1}{100}\times\text{ (Height of actual model)}[/tex]
[tex]=\dfrac{1}{100}\times305.5\\\\=3.055\text{ feet}[/tex]
Hence, the actual model is 3.055 feet tall.

Multiple Choice An equation of the line
whose slope is 3 and whose y-intercept is 8 is
? ?
A y = 8x + 3
C y = – 3x + 8
Ey = 3x - 8
B y = 3x + 8
D y = - 3x – 8
Answer:
y = 3x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 and c = 8 , thus
y = 3x + 8 ← equation of line

The table shows a relationship between x and y. What is the constant of proportionality, k, which relates the variable y to the variable x?
Answer:
F. [tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Constant of proportionality, k, = [tex] \frac{y}{x} [/tex]
The ratio of each given of values on the table will give you the same value, which represents k.
Thus, using the pair, (2, 1.5), k can be calculated as follows:
[tex] k = \frac{y}{x} = \frac{1.5}{2} [/tex]
Multiply the numerator band denominator by 10 to eliminate the decimal point.
[tex] = \frac{1.5*10}{2*10} = \frac{15}{20} [/tex]
Simplify
[tex] k = \frac{3}{4} [/tex]

Alonso brings $21 to the market to buy eggs and avocados. He gets eggs that cost $2.5. Then he notices that the store only sells avocados in bags of 3 for $5. He wants to buy aS many avocados as he can with his remaining money. What is the largest number of avocados that Alonso can afford
Answer:
Step-by-step explanation:
21≤2.50+5s subtract 2.50 from both sides
18.50≤5s divide by 5
s≥3.7 he can buy up to 3 bags at $5 each
Alonso brings $21 to the market to buy eggs and avocados. He gets eggs that cost $2.50. Then he notices that the store only sells avocados in bags of 3 for $5. He wants to buy as many avocados as he can with his remaining money. What is the largest number of avocados that Alonso can afford?
Answer:
9 avocados
Step-by-step explanation:$21.00 - $2.50 = $18.50
3 × $5.00 = $15.00
$18.50 - $15.00 = $3.50
$15 = 3 bags of avocados = 3 bags × 3 avocados = 9 avocados

Answer:
Juan earns 10 dollars a week at his job
Step-by-step explanation:
All the fudge machines at a chocolate factory work at the same rate. Six machines working simultaneously can complete a big order in 22 hours. How many hours would it take to fill the order if the number of working machines decreased by factor of 4?
Answer:
88 hours
Step-by-step explanation:
Since we are decreasing the number of machines by a factor of four and all the machines work at the same rate, we are simply going to increase the work hours by a factor of 4
Increasing the work hours by a factor of 4 will yield 22 * 4 = 88 hours
So it will take 88 hours to fill the order if the number of machines is deceased by a factor of 4

Answer:
A. y = [tex]\frac{2}{5}[/tex]x + 1
Step-by-step explanation:
A linear function is a function that has an exponential value of zero or one and that, when graphed, is a straight line. The only equation that fits this description is answer choice A. We can also use the process of elimination to figure out which answer choice is correct.
A: A is the correct answer because it has an exponential value of one, meaning that it will be a straight line.
B: B is incorrect because the x has an exponential value of 2, which tells us that the equation is quadratic, not linear. If you were to graph this equation, it would look like a parabola, not a straight line.
C: C is incorrect for the same reason as answer choice B, the exponential value of this equation is more than one, meaning that the equation can't be linear.
D: D is incorrect because it contains a radical [tex]\sqrt{x}[/tex]. When [tex]\sqrt{x}[/tex] is graphed, it looks like half of a parabola, which isn't a straight line.
The Singer family had a moving sale. The next day they made this deposit with no cash back: 25 twenties, 19 tens, 28 fives, 18 ones; 15 quarters; and checks for $25, $20, and $85. What was the amount of their deposit?
The amount of their deposit will be $981.75
SumSum refers to the addition of two or more numbers.
How to find the amount of their deposit?The amount of their deposit will be the sum of no cashback deposit and the checks.
This means that the amount of their deposit will be 25 twenties + 19 tens + 28 fives + 18 ones + 15 quarters + $25 + $20 + $85.
By Solving it, we will get
[tex](25\times 20)+(19\times 10)+(28\times 5)+(18\times 1)+(15\times \dfrac{1}{4})+25+20+85=500+190+140+18+3.75+25+20+85\\=981.75[/tex]

Brittany needed new tires for her truck. She went to the auto shop and bought 4 tires on sale for $85.95 each. The salesman told her that she saved a total of $96.16. If Brittany saved the same amount on each tire, what was the original price of each tire?
Answer:
Answer: $109.99
Step-by-step explanation:
The total amount saved, $96.16, should be divided by the number of tires, 4. The answer is $24.04. Add $24.04 to the price of a single tire, $85.95, and the answer is $109.99, the original price of one tire.
A cylindrical can, open at the top, is to hold 200 cm3 of liquid. Find the height and radius that minimizes the amount of material needed to manufacture the can.
Answer:
h = 5.42
r = 5.42
Step-by-step explanation:
Find h with respect to r:
V = πr²h = 500
h = 500/πr²
Plug this into the surface area equation:
SA = πr² + 2πrh
= πr² + 2πr(500/πr²)
= πr² + 1000/r
Differentiate and set to 0, solve for r:
dSA/dr = 2πr - 1000/r² = 0
2πr = 1000/r²
r³ = 500/π
r = (500/π)^1/3
≈ 5.42 cm
find h:
h = 500/πr²
= 500/[π(5.42)²]
= 5.42cm

Answer:
[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]
As the highest power of the x-variable is 3 with the leading coefficients of 1.
So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.solving to get the zeros
[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]
[tex]0=x^3-6x^2+3x+10[/tex] ∵ [tex]f(x)=0[/tex]
as
[tex]Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]
so
[tex]\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]
Using the zero factor principle
if [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
[tex]x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]
[tex]x=-1,\:x=2,\:x=5[/tex]
Therefore, the zeros of the function are:
[tex]x=-1,\:x=2,\:x=5[/tex]
[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Therefore, the last option is true.
