Answer:
T=112.5+0.50*b (since there was not a given number of beads)
what is 3.825 as a fraction with a guide?
Answer:
153/40
Step-by-step explanation:
The first step to finding the fraction is to get rid of the decimal points as fractions do not have decimals. To do this we can multiply it by 1000 which gives us 3825. To have this equal to the original number we add ÷1000 on the denominator which gives us 3825/1000 which is a fraction still equal to the original number (3825÷1000=3.825). Which can further be simplified to 153/40 (both numbers divisible by 25). This is the simplest fraction which can express the number 3.825 (153/40=3.825).

2/3 * 9 = ? PLEASE HELP
Answer:
6
Step-by-step explanation:
The value of the digit 9 is ten times as much as the 9 in 893,417.
Answer: 943,212
Step-by-step explanation:
Suppose that you want to know the value of a given digit in a given number, where the digit is x.
Now, you should count the position of this digit, starting at the decimal point and counting to the left.
This position, a number n, will give the value of our digit as:
Value = x*10^(n-1)
in the number 893,417 the digit 9 is in the fifth place (counting from right to left).
Then the value of this 9 is:
9*10^(5 - 1) = 90,000
Now, if we want something ten times larger than this, we have:
N = 10*90,000 = 900,000
Now the 9 is in the sixth place, then we must find a number with a 9 in the sixth place, for example, 943,212.

A map has a scale of
2 in. = 17 mi. If you measured the distance between two cities to
be 19 in. on the map, how many miles would it actually be?
If necessary, round your answer to the nearest tenth.
Answer:
161.5 miles
Step-by-step explanation:
19 inches is 9.5 times 2 inches. So, the actual distance is 9.5 times 17 miles:
9.5 × 17 miles = 161.5 miles
Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.
Answer: Because the a-value is negative.
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
"a" is the vertical stretch-a is a reflection over the x-axish is the horizontal shift (positive = right, negative = left)k is the vertical shift (positive = up, negative = down)Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
Fruit juice in 4/5 pint cartons is sold by the park in 5/6 pint mugs. How many mugs are in a carton?
Answer:
Number of mugs in cartoon = 24 / 25
Step-by-step explanation:
Given:
Pints of cartoon = 4/5
Pints of mugs = 5/6
Find:
Number of mugs in cartoon
Computation:
Number of mugs in cartoon = Pints of cartoon / Pints of mugs
Number of mugs in cartoon = (4/5) / (5/6)
Number of mugs in cartoon = 24 / 25

Evaluate the limit with either L'Hôpital's rule or previously learned methods.lim Sin(x)- Tan(x)/ x^3x → 0
Answer:
[tex]\dfrac{-1}{6}[/tex]
Step-by-step explanation:
Given the limit of a function expressed as [tex]\lim_{ x\to \ 0} \dfrac{sin(x)-tan(x)}{x^3}[/tex], to evaluate the following steps must be carried out.
Step 1: substitute x = 0 into the function
[tex]= \dfrac{sin(0)-tan(0)}{0^3}\\= \frac{0}{0} (indeterminate)[/tex]
Step 2: Apply L'Hôpital's rule, by differentiating the numerator and denominator of the function
[tex]= \lim_{ x\to \ 0} \dfrac{\frac{d}{dx}[ sin(x)-tan(x)]}{\frac{d}{dx} (x^3)}\\= \lim_{ x\to \ 0} \dfrac{cos(x)-sec^2(x)}{3x^2}\\[/tex]
Step 3: substitute x = 0 into the resulting function
[tex]= \dfrac{cos(0)-sec^2(0)}{3(0)^2}\\= \frac{1-1}{0}\\= \frac{0}{0} (ind)[/tex]
Step 4: Apply L'Hôpital's rule, by differentiating the numerator and denominator of the resulting function in step 2
[tex]= \lim_{ x\to \ 0} \dfrac{\frac{d}{dx}[ cos(x)-sec^2(x)]}{\frac{d}{dx} (3x^2)}\\= \lim_{ x\to \ 0} \dfrac{-sin(x)-2sec^2(x)tan(x)}{6x}\\[/tex]
[tex]= \dfrac{-sin(0)-2sec^2(0)tan(0)}{6(0)}\\= \frac{0}{0} (ind)[/tex]
Step 6: Apply L'Hôpital's rule, by differentiating the numerator and denominator of the resulting function in step 4
[tex]= \lim_{ x\to \ 0} \dfrac{\frac{d}{dx}[ -sin(x)-2sec^2(x)tan(x)]}{\frac{d}{dx} (6x)}\\= \lim_{ x\to \ 0} \dfrac{[ -cos(x)-2(sec^2(x)sec^2(x)+2sec^2(x)tan(x)tan(x)]}{6}\\\\= \lim_{ x\to \ 0} \dfrac{[ -cos(x)-2(sec^4(x)+2sec^2(x)tan^2(x)]}{6}\\[/tex]
Step 7: substitute x = 0 into the resulting function in step 6
[tex]= \dfrac{[ -cos(0)-2(sec^4(0)+2sec^2(0)tan^2(0)]}{6}\\\\= \dfrac{-1-2(0)}{6} \\= \dfrac{-1}{6}[/tex]
Hence the limit of the function [tex]\lim_{ x\to \ 0} \dfrac{sin(x)-tan(x)}{x^3} \ is \ \dfrac{-1}{6}[/tex].
Simplify. Please provide steps on how to solve so I can learn.
Answer: Choice C
[tex](xy)^{1/2}[/tex] which is equivalent to [tex]\sqrt{xy}[/tex]
===============================================
Explanation:
The exponent for the y term inside the parenthesis is 1/6 and then that expression is raised to the 3rd power. The exponents multiply to (1/6)*3 = 3/6 = 1/2
This means [tex]\left(y^{1/6}\right)^3 = y^{1/2}[/tex]
Having an exponent of 1/2 is the same as applying the square root, so,
[tex]\sqrt{x} = x^{1/2}[/tex]
Meaning,
[tex]y^{1/2}\sqrt{x} = y^{1/2}x^{1/2} = (xy)^{1/2} = \sqrt{xy}[/tex]

To make fruit salad,Maria bought 2 1/4 pounds of apples,and 1 1/3 pounds.How much fruit salad did this make
Answer:
If this was all the fruit, 3 and 7/12
Step-by-step explanation:
1/4 and 1/3 LCM is 12
1/4=3/12
1/3=4/12
2+1=3
3/12+4/12=7/12
3+7/12= 3 7/12
The point (0, –4) is located
I'm going to assume you're asking where the point is located on a coordinate plane.
We have x = 0 and y = -4.
So, we start at (0, 0) and move down 4 units.
Best of Luck!
Look at the correlation between Risk-Taking (R) and Relationship Happiness (HAPPY). Use the standard alpha level of 5%. How would you describe the relationship?
1. The relationship is non-significant.
2. There is a significant negative relationship.
3. There is a significant positive relationship.
4. The correlation is zero.
Image of the correlation between Risk-Taking (R) and Relationship Happiness (HAPPY) is missing, so i have attached it.
Answer:
Option 1 - The relationship is non - significant
Step-by-step explanation:
From the image attached, we can see that under the correlations table;
For correlation between relationship happiness and risk taking;
σ(sigma) = 0.053
Similarly, for correlation between risk taking and relationship happiness;
σ(sigma) = 0.053
.
Now,σ(sigma) = 0.053 is more than the standard alpha level of 5%(0.05). Thus, we fail to reject the null hypothesis since it is non - significant.
What’s the perimeter of the tabletop in feet?
Answer:
Perimeter = 14.0942 ft (aprox)
Step-by-step explanation:
1 ft = 12 inches
1 inch = 1/12 = 0.08333 ft
4 inch = 4*0.08333 = 0.3333 ft
then:
there are:
4 quarters of circle = 4/4 = 1 complete circleperimeter = 2π r
π = 3.1416
r = radius
perimeter = 2*3.1416*0.3333ft
perimeter = 2.0942 ft (aprox)
4 sides (3ft each)perimeter = 4*3ft
perimeter = 12ft
Total perimeter:
2.0942ft +´12ft = 14.0942 ft

Find the value of the expression for the given values.
6x-2 for x = -2, x = 6, and x = -5
If x= - 2. then 6x - 2 =
If x = 6, then 6x - 2 =
If x= - 5. then 6x-2=
Answer:
If x= - 2. then 6x - 2 = -14
If x = 6, then 6x - 2 = 34
If x= - 5. then 6x-2= -32
Step-by-step explanation:
You have to substitute the value of x in the expression.
If x = -2,
6x-2 = 6*(-2) - 2 = -12-2 = -14
