A rancher uses a bucket that holds 15,000 milliliters of water to fill a water trough for her horse. The trough holds 2.7 x 10^5 milliliters of water. How many buckets of water will the rancher need to fill the trough?
Step-by-step explanation:
the volume of the bucket is
15,000 = 1.5 × 10⁴ ml
the trough holds
2.7 × 10⁵ ml
by calculating how often the volume of the bucket fits into the volume of the trough, we will know how many buckets of water are needed :
2.7 × 10⁵ / (1.5 × 10⁴) = 2.7/1.5 × 10⁵/10⁴ = 2.7/1.5 × 10¹ =
= 27/1.5 = 18
the rancher needs 18 buckets of water to fill the trough.
A crate is 3/4 yard long and 2/3 yard wide. The crate is also 2 feet tall. What is the area of the top of the crate?
Answer:
1/2 or 6/12
Step-by-step explanation:
To get the area of the crate's top, multiply the length and width together. Should not multiply the height by anything because it simply measures the height of the box and not the length or breadth of any of its bases (the top and bottom of the box). When you multiply the length by 3/4 and the breadth by 2/3, you should obtain 6/12, or 1/2 yard squared, as your answer for the area of the crate's top.

Answer:
9.2 cm and 15% increase
Step-by-step explanation:
1.15*8 = 9.2
percentage increase
new square = 9.2*9.2 =84.64
old area=8*9.2 = 73.6
percentange increase = (84.64-73.6)/73.6 = 15%
Increase the width
8+0.15(8)8+1.29.2cmAs sides of square are equal
The sides are 9.2cmArea increases same as length i.e 15%
What is 12 times 0.15
To make this simpler, we know that [tex]0.15=\frac{15}{100}[/tex], so
12 times [tex]\frac{15}{100}[/tex] = [tex]12 * \frac{15}{100} =\frac{180}{100} = 1.8[/tex]

84x = 80x + 40=> 84x - 80x = 80x + 40 - 80xSimplify the LHS:

After sitting out of a refrigerator for a while, a turkey at room temperature (72°F) is
placed into an oven. The oven temperature is 305°F. Newton's Law of Heating
explains that the temperature of the turkey will increase proportionally to the
difference between the temperature of the turkey and the temperature of the oven, as
given by the formula below:
T = T. + (T. – T.)e-kt
To = the temperature surrounding the object
To = the initial temperature of the object
t the time in hours
T = the temperature of the object after t hours
k = decay constant
The turkey reaches the temperature of 123°F after 2 hours. Using this information,
find the value of k, to the nearest thousandth. Use the resulting equation to
determine the Fahrenheit temperature of the turkey, to the nearest degree, after 4.5
hours.
Enter only the final temperature into the input box.
Answer:
156 °F
Step-by-step explanation:
Newton's Law of Heating results in the exponential function you show in your problem statement. We can use the given starting and "in-progress" temperatures and times to solve for the value of the factor "k" in the exponential function.
[tex]T(t)=T_\infty+(T_0-T_\infty)e^{-kt}\\\\T(2.5)=123=305+(72-305)e^{-k\cdot2.5}\qquad\text{substitute given temps and times}\\\\\dfrac{123-305}{72-305}=e^{-2.5k}=\dfrac{182}{233}\qquad\text{subtract 305, divide by $(72-305)$}\\\\k=\dfrac{-1}{2.5}\ln\dfrac{182}{233}\approx0.0988127\approx0.099\qquad\text{rounded to 3 places}[/tex]
Then the temperature after 4.5 hours is ...
T(4.5) = 305 -233e^(-0.099·4.5) ≈ 156 . . . . °F
_____
Additional comment
It will take about 6.3 hours for the turkey temperature to reach 180 °F.

A bank offers an investment account with an annual interest rate of 1.14% compounded monthly. Lashonda invests $3400 into the account for 2 years. Answer the questions below. Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas х 5 ? (a) Assuming no withdrawals are made, how much money is in Lashonda's account after 2 years?
Answer:
≈$3478.4
Step-by-step explanation:
Using the compound interest formula:
[tex]A = P(1+\frac{r}{n})^{nt}[/tex]
A = Total
P = Principle
r = Interest Rate
n = No. of times applied in each time period
t = No. of periods
In this case,
P = 3400
r = 1.14% = 0.0114
n = 12 (months)
t = 2 (years)
Hence,
[tex]A = 3400(1+\frac{0.0115}{12})^{12*2}[/tex]
[tex]A = 3478.372836......[/tex]
A ≈ 3478.4 (nearest cent)

There is a pair of parallel sides in the following shape.
what is the area of the shape? units^2
Answer:
A = 15 units²
Step-by-step explanation:
The figure has 1 pair of parallel sides and is therefore a trapezium.
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height between bases and b₁, b₂ are bases
here h = 3, b₁ = 3 , b₂ = 7 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 7) = 1.5 × 10 = 15 units²
The area of the square is the square of one of its sides. The area of the plate is 15 units².
What is the area of a square?The area of the square is the square of one of its sides.
[tex]\text{Area of square} = a^2[/tex]
What is the area of a triangle?The area of a triangle is half the product of its base and height.
[tex]\rm\text{Area of Triangle} = \dfrac{1}{2} \times Base \times Height[/tex]
The shape of the plate can be divided into two parts a square of side 3 cm and a triangle with of base 4 cm and a height of 3 cm, therefore, the area of the plate is,
[tex]\text{The area of the shape} = \text{Area of the triangle} + \text{Area of the square}[/tex]
[tex]= (\dfrac{1}{2} \times 4 \times 3) + (3 \times 3)\\\\= 6 + 9\\\\=15\rm\ units^2[/tex]
Hence, the area of the plate is 15 units².

[tex]\tiny\displaystyle\rm \sum_{q=1}^{\infty}\left(a^{q}\left(1+\sum_{r=1}^{\infty} \frac{\prod \limits_{i=0}^{r+1}(q-i)}{\Gamma(r+1)}\left(\frac{b x^{m}}{a}\right)^{r}\right)\right)=\frac{a+b x^{m}}{1-\left(a+b x^{m}\right)}[/tex]
if all variables belong to natural number.
Recall that if |x| < 1, then
[tex]\displaystyle \frac1{1-x} = \sum_{k=0}^\infty x^k[/tex]
So if |a + bxᵐ| < 1, then
[tex]\displaystyle \frac{a+bx^m}{1 - (a+bx^m)} = \sum_{q=1}^\infty (a+bx^m)^q = \sum_{q=1}^\infty a^q \left(1 + \frac{bx^m}a\right)^q[/tex]
By the binomial theorem,
[tex]\displaystyle \left(1 + \frac{bx^m}a\right)^q = \sum_{r=0}^q \binom qr \left(\frac{bx^m}a\right)^r[/tex]
The binomial coefficient is defined as
[tex]\dbinom nk = \dfrac{n!}{k!(n-k)!}[/tex]
if 0 ≤ k ≤ n, and 0 otherwise. Then we can rewrite the sum as
[tex]\displaystyle \left(1 + \frac{bx^m}a\right)^q = \sum_{r=0}^\infty \binom qr \left(\frac{bx^m}a\right)^r[/tex]
and pulling out the first term,
[tex]\displaystyle \left(1 + \frac{bx^m}a\right)^q = 1 + \sum_{r=1}^\infty \binom qr \left(\frac{bx^m}a\right)^r[/tex]
Finally,
[tex]\dbinom qr = \dfrac{q!}{r! (q-r)!} \\\\\\ = \dfrac{q(q-1)(q-2)\cdots(q-(r-1))(q-r)(q-(r+1))\cdots3\cdot2\cdot1}{r! (q-r) (q-(r+1)) (q-(r+2))\cdots3\cdot2\cdot1} \\\\\\ = \dfrac{q(q-1)(q-2)\cdots(q-(r-1))}{r!} \\\\ = \dfrac{\prod\limits_{i=0}^{r-1}(q-i)}{\Gamma(r+1)}[/tex]
since n! = Γ(n + 1). (I think the given upper limit in the product may be a mistake.)
