The difference of five times the cube of x and two times the square of x is 18
Answer:
x=3√2 or x=4
Step-by-step explanation:
5*x^3-2*x^2=18
x^2(5x-2)=18
x^2=18 or 5x-2=18
x=√18 or 5x=20
x=√9*2 or x=4
x=3√2 or x=4
Sarah is cutting ribbons for a pep rally. The length of each ribbon needs to be 3.29 inches. If she needs 1,00 ribbons, what is the length of ribbon Sarah needs?
Answer:
3,290 inches of Ribbon
Step-by-step explanation:
Assuming that Sarah needs a total of 1,000 Ribbons we would simply need to multiply this total amount by the size of each individual Ribbon, which according to Sarah is 3.29 inches. This is because this would be like adding the size of each individual ribbon to get the total length. Like so...
1,000 * 3.29 = 3,290inches
Therefore, Sarah would need a total of 3,290 inches or
3,290 / 12 = 274.16ft of ribbon
Mr joseph bought 9 pounds of fertilizer for his lawn he uses 2 2/3 pounds for his backyard and 1 2/9 pounds fo rdd hi front yard how much fert I'll lizer is left
Answer:
5 pounds
Step-by-step explanation:
Total pounds of fertilizer purchased purchased for lawn = 9 pounds
Amount used for backyard = 2 2/3 pounds
Amount used for front yard = 1 2/9
Amount of fertilizer left :
Total amount purchased - total. Amount used
Total amount used :
(amount used for backyard + amount used for front yard)
(2 2/3 + 1 2/9) = (8/3 + 11/9) = (24 + 11) / 9
= 36 / 9
= 4 pounds
Amount of fertilizer left :
Total amount purchased - total. Amount used
9 pounds - 4 pounds
= 5 pounds
Answer:
5 pounds

The 95% confidence interval for a certain proportion p is from 0.23 to 0.63. We conducted a hypothesis test for p. The null hypothesis is H0:p=a . The alternative hypothesis is Ha:p≠a. What is the mean for the all possible values of a which would not be rejected as plausible values of the population proportion at a 5% significance level? The mean for the all possible values of a which would not be rejected as plausible values of the population proportion at a 5% significance level is .
Answer:
The answer is "0.43"
Step-by-step explanation:
Population proportion normal distribution is suggested as following:
Confidence Interval = [tex]P \pm Z \times \sqrt{\frac{P \times (1 -p)}{n} }[/tex]
Confidence Interval = [tex]P \pm E[/tex]
Bottom bound [tex]= P-E = 0.23[/tex]
Lower bound [tex]= P + E = 0.63[/tex]
Through connecting additional formulas, we're getting,
[tex]\to 2P = 0.23+0.63\\\\\to 2P = 0.86\\\\\to P= \frac{0.86}{2}\\\\[/tex]
[tex]= 0.43[/tex]
The average with all attribute outcomes a whereby the demographic proportion at 5 % isn't dismissed as plausible values is 0.43.

dose anybody know the answer?
Answer:
they want a fomula that is in respect to 'b" sooo..
Step-by-step explanation:
just do the algebra.... like so..
a/b=c
move 'b" across = sign by multiplying by 1/b like soo.
(1/b)*(a/b)= (1/b)*c
a=c/b
then move the 'c' to the other side of the = sign by multiplying by 1/c
(1/c)*a = (1/c)*(c/b)
a/c = b
makes sense , also.. as a way to speed that up.. just remember you can just swap the 'b' and 'c' in that first equation
b = a/c
A pair of basketball shoes normal shoes is 120 jordan bought it at a discount of 10% he had to pay 8% tax on the discounted price. If jordan put 15% of the cost including tax as a down payment how much money did he have to pay for the down payment
9514 1404 393
Answer:
17.50 down
Step-by-step explanation:
After the discount, the price is 100% -10% = 90% of the original.
After the tax, the amount owed is 100% +8% = 108% of the discounted price.
The amount Jordan put down is 15% of the amount after tax, so is ...
120(0.90)(1.08)(0.15) ≈ 17.50 . . . down payment
Answer:
$17.50

R(3, 8) is dilated by a factor of 5, centered at (2, 10). Write the coordinates of R’.
Answer:
The coordinates of R' are [tex]R'(x,y) = (8,-2)[/tex].
Step-by-step explanation:
According to Linear Algebra, dilation consist in expanding a given vector with respect to one of its endpoints by a scalar. That is:
[tex]R'(x, y) = C(x,y) + k\cdot [R(x,y)-C(x,y)][/tex] (Eq. 1)
Where:
[tex]R(x, y)[/tex] - Original location with respect to origin, dimensionless.
[tex]C(x,y)[/tex] - Point of reference with respect to origin, dimensionless.
[tex]k[/tex] - Dilation factor, dimensionless.
[tex]R'(x, y)[/tex] - Dilated point with respect to origin, dimensionless.
If we know that [tex]R(x,y) = (3,8)[/tex], [tex]C(x,y) = (2,10)[/tex] and [tex]k = 5[/tex], then the dilated point is:
[tex]R'(x,y) = (3,8) +5\cdot [(3,8)-(2,10)][/tex]
[tex]R'(x,y) = (3,8)+5\cdot (1,-2)[/tex]
[tex]R'(x,y) = (8,-2)[/tex]
The coordinates of R' are [tex]R'(x,y) = (8,-2)[/tex].

number of bracelets=
number of necklaces=
Answer:
number of bracelets= 5
number of necklaces= 4
Step-by-step explanation:
* I don't know how to show a matrix with a keyboard so I'm just going to do two lines of brackets to represent the matrix.
b=bracelets
n=necklaces
[8 20 | 120]
[b n | 9 ]
You should put this into a graphing calculator:
[8 20 | 120]
[1 1 | 9 ]
Then use reduced row echelon form which equals:
[1 0 | 5]
[0 1 | 4]

James, Priya, and Siobhan work in a grocery store. James makes $9.00 per hour. Priya makes 20% more
than James, and Siobhan makes 5% less than Priya. How much does Siobhan make per hour?
Answer:
Step-by-step explanation:
Don't be too quick to answer 15% of some number. It may be right, but it is likely not.
James makes 9.00 dollars an hour
Priya makes 20% more than James. Stop. Figure that out.
9.00 * 1 + 25/100 * 9 = 9.00 + 2.25 = 11.25
Now, you can figure out 5% less.
Siobhan = 11,25 - 5/100 * 11.25
Siobhan = 11.25 - 0.05 * 11.25
Siobhan = 11.25 - 0.5625
Siobhan = 10.6875 = 10.69
There is no other way that I know of to go directly to Siobhan's wage other than doing it the long way -- at least for the level of math you are taking.
9 * (1.2 - 0.05) might work.
9 * (1.15)
= 10.35 which is close, but not correct.
Moral: do the math. Don't accept a guess as an answer.
Factor the GCF4x^2+36x=-72
Answer:
x^2 + 9x = - 18
Step-by-step explanation:
GCF is 4 So divide both sides by 4
4x^2 / 4 = x^2
36x/4 = 9x
- 72 /4 = -18
A video game store sold 135 copies of a new release game in June. In July, they sold 108 copies of the same game. What is the percent decrease in the sales of this game from June to July?
percent decrease: decrease/old price * 100%
Subtract:
135 - 108 = 27
Fill into formula,
= 27/135 * 100%
= 1/5 * 100%
= 0.20 * 100%
= 20%
therefore, the percent decrease is 20%!

A cave explorer travels 12.9 m eastward, 3.4 m northward, and finally 3.4 m
southward. In which direction did the explorer end up traveling?
Answer:
12.26 m, north-west
Step-by-step explanation:From the figure the displacement can be calculated by the Pythagorean law. In this the triangle ABC is the right angle triangle with hypotenous h, base 12 m, and height 2.5 m. Therefore the net displacement is 12.26 m and the displacement we know it is vector quantity and it is the shortest distance between the two points. Therefore the displacement is from point B to A. Then the net displacement is the direction in the north-west direction with a magnitude of 12.26 m.
Find the distance between the two points in simplest radical form.
(6, 7) and (8,2)
Answer:
+sqrt(29)
Step-by-step explanation:
Note that the change in x (horizontal leg) is 8 - 6, or 2, and that the change in y (vertical leg) is |2 - 7|, or 5. According to the Pythagorean Theorem, the length of the hypotenuse of the right triangle created here is:
distance = +sqrt(2^2 + 5^2), or +sqrt(29)
