To divide 30 into five parts such that the first and last parts are in the ratio of 2:3, we can follow these steps:
1. Determine the ratio between the first and last parts. In this case, it is 2:3.
2. Add the ratio values together to find the total number of parts: 2 + 3 = 5.
3. Divide the total value (30) by the total number of parts (5) to find the value of each part: 30 / 5 = 6.
4. Multiply the value of each part by the respective ratio values to obtain the individual parts:
- First part: 2 * 6 = 12
- Second part: 6
- Third part: 6
- Fourth part: 6
- Last part: 3 * 6 = 18
Therefore, the five parts of 30, with the first and last parts in the ratio of 2:3, are 12, 6, 6, 6, and 18.

What is w/ 6 - 6? If w=42?
Answer choices:
A) 4
B) 1
C) -1
D) 42
Hi!
Your answer would be: B-1
Reason being: Using P.E.M.D.A.S., we divide 42 (or, w) by 6, which equals 7.
now, 7 minus 6 equals 1.
__________________________________________________________
42/6-6
=7-6
=1

What does the transformation f(x)↦3f(x) do to the graph of f(x)?
stretches horizontally or vertically ?
Using translation concepts, it is found that the transformation f(x)↦3f(x) stretches vertically the graph of f(x) by 3 units.
In the transformation f(x) -> 3f(x), the function f(x) is multiplied by 3.When a function is multiplied by a constant with absolute value greater than 1, it is stretched vertically.An horizontal stretch is represented by f(x) -> f(ax), which is not the case here.Hence:
The transformation f(x)↦3f(x) stretches vertically the graph of f(x) by 3 units.

Answer:
9/10
1/2+2/5
Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10
1/2 ∗ 5/5 = 5/10
5/2∗ 2/2= 4/10
Since these fractions have the same denominator, we can just add the numerators
5/10+ 4/10 = 9/10
Answer:
1/10
Step-by-step explanation:
Begin by writing the given phrase as an equation. The sum of two-fifths and f can be written 2/5+f, and that term is equal to one-half, written 1/2. Written together,
2/5+f=1/2.
Begin by subtracting 25 from each side,
2/5+f−2/5=1/2−2/5.
Simplify and rewrite with a common denominator,
f=1/2⋅5/5−2/5⋅2/2
and simplify again,
f=5−4/10,
and solve for f,
f=110.

That is g(-1) = 3, or x=-1 for g(x) = 3.
Answer:
x=-1
Step-by-step explanation:
g(x)=y = 3
as you can see on the graph, (-1,3)➡ -1 value of x is g(x)=3 ➡g(-1)=3

A ladder 10 feet long rests against a vertical wall. Initially, the top of the ladder is 8 feet above the ground. If the top of the ladder is sliding down the wall at a rate of 2 feet per second, how fast is the bottom of the ladder sliding away from the wall 1 second after the ladder starts sliding? Answer the question in a complete sentence and include appropriate units
Step-by-step explanation:
Let vertical height of ladder from ground be y and
horizontal distance of the base of the ladder from the wall be x respectively.
Length of the ladder = l (constant) = 10 ft
Using Pythagoras theorem:
[tex] {l}^{2} = {y}^{2} + {x}^{2} [/tex]
Differentiate both sides w.r.t time
[tex]0 = 2y \frac{dy}{dt} + 2x \frac{dx}{dt} [/tex]
[tex]y \frac{dy}{dt} + x \frac{dx}{dt} = 0[/tex]
We know that (After 1 sec, y = 6 ft and x = 8 ft ; dy/dt = 2 ft/sec)
[tex]6\times 2 + 8\frac{dx}{dt} = 0[/tex]
[tex] \frac{dx}{dt} = - 1.5 ft \: per \: sec[/tex]
( Ignore - ive sign)
Therefore, bottom of the ladder is sliding away from the wall at a speed of 1.5 ft/sec one second after the ladder starts sliding.
Cody Summer sells tires for tractor-trailers. He earns 4.5 percent commission on the first $6,000, 8 percent on the next $6,000, and 12 percent on sales over $12,000. Last month he sold $18,000 worth of tires. What was his total commission?
Answer:
$1470
Step-by-step explanation:
Summer earned 4.5% on $6000 +8% on $6000 + 12% on ($18000-12000) = $6000, for a total of 24.5% of $6000.
commission = 0.245 · $6000 = $1470
Summer earned a total commission of $1470.

solve x +2y = -2, 4x + 2y = -17
Answer:
x = -5
y = 3/2
Step-by-step explanation:
x+2y = -2
4x + 2y = -17
_______________
-4(x+2y = -2)
4x+ 2y = -17
_______________
-4x - 8y = 8
4x + 2y = -17
_______________
-6y = -9
y = 3/2
plug this value back into 1 of the 2 equations in the original problem to solve for x
x+2y=-2
x + 2(3/2) = -2
x + 3 = -2
x = -5

Answer: w=A + 5
Step-by-step explanation:
Thats my answere
Answer:
w=A+5

We are starting with A=w-5 but to make things a little easier, we will flip the equation so it will look like w-5=A, now let's solve it
Add 5 to both sides,
w-5+5=A+5 once we simplify this we get our final answer,
w=A+5

Chi square Daphne likes to ski at a resort that is open from December through April. According to a sign at the resort, 20, percent of the snow falls occur in December, 25, percent in January, 20, percent in February, 20, percent in March, and 15, percent in April. She wondered if the snow falls in her hometown followed this distribution, so she took a random sample of 80 days between December and April with snowfall and recorded their months. Here are her results:_________.
Answer:
There is not enough evidence to suggest that the snow falls in Daphne's hometown does not follow the given distribution.
Step-by-step explanation:
The missing data for the random sample of 80 days between December and April with snowfall is:
Month Days
December 16
January 11
February 16
March 18
April 19
The Chi-square goodness of fit test would be used to determine whether the snow falls in Daphne's hometown followed the given distribution.
The hypothesis for the test can be defined as follows:
H₀: The snow falls in Daphne's hometown does not follow the given distribution.
Hₐ: The snow falls in Daphne's hometown followed the given distribution.
Assume that the significance level of the test is, α = 0.05.
The Chi-square test statistic is given by:
[tex]\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}[/tex]
The value of Chi-square test statistic is computed in the Excel sheet below.
[tex]\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}=8.383[/tex]
Compute the p-value as follows:
[tex]\text{p-value}=P(\chi^{2}_{(4)}>8.383)=CHISQ.DIST.RT(8.383,4)=0.0785[/tex]
The p-value of the test is 0.0785.
Decision rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
p-value = 0.0785 > α = 0.05.
The null hypothesis will not be rejected.
Conclusion:
There is not enough evidence to suggest that the snow falls in Daphne's hometown does not follow the given distribution.
