Answer:
15% '
Step-by-step explanation:
Price yesterday = $180
Price today = $207
Increase in price = $(207 - 180)
=> $27
Percent increase =
Increase / Price of yesterday
=> 27 / 180 * 100
=> 3 / 2 * 10
=> 30 / 2
=> 15
15%
Therefore, the rise in the price of the item = 15%

The width of a rectangle is 2 meters less than the length. The area of the rectangle is 15m. Find
the dimensions
Answer:
The length is 5 meters and the width is 3 meters.
Step-by-step explanation:
The dimensions of the rectangle are 5 meters by 3 meters.
Let's say the length of the rectangle is l and the width is w. We are given that w = l - 2 and lw = 15.
We can substitute the first equation into the second equation to get:
l(l - 2) = 15
This simplifies to:
[tex]l^2[/tex] - 2l - 15 = 0
We can factor this equation to get:
(l + 3)(l - 5) = 0
This means that either l = -3 or l = 5.
Since the length of a rectangle cannot be negative, we know that l = 5.
Substituting this value back into the equation w = l - 2, we get:
w = 5 - 2 = 3
Therefore, the dimensions of the rectangle are 5 meters by 3 meters.

Answer:
2^3 * 7 + 7^2
Step-by-step explanation:
1) divide 28 by 2 = 14
2) divide 14 by 2 = 7
3) this means that 2 * 2 * 7 = 28
4) you can then take those 2 twos and multiply them with the first 2 and make 2^3
5) the square root of 49 is 7 so that is just 7^2
6) plug in all these new values for the originals and you get the answer above
Answer:
first you gotta calculate 2 -28 +49
After getting the answer solve the expressions to see which one is equivalent to 2-28 +49 (I think)
The Jackson family borrowed $240,000 to purchase a house and, over thirty years they had to repay 250% of what they borrowed. What is the total amount of money the Jackson family paid for their loan? Brainly
Answer:
Step-by-step explanation:
Given
[tex]Loan = \$240,000[/tex]
[tex]Amount = 250\%[/tex]
Required
Determine the total amount
This is calculated by multiplying the loan amount by the percentage:
i.e.
[tex]Payment = Amount\% * Amount[/tex]
[tex]Payment = 250\% * \$200000[/tex]
[tex]Payment = \$500000[/tex]
Hence, the total payment is $500000

Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To find the slope of the graph, we use the expression below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
We pick two points; (-2, 1) and (4, 4)
x₁ = -2,
y₁ = 1
x₂ = 4
y₂ = 4
Now insert the parameters and solve;
Slope = [tex]\frac{4-1}{4- (-2)}[/tex] = [tex]\frac{1}{2}[/tex]

After releasing of radioactive material into.The atnosphere from.A nuclear.Powe plant in a country in 1988, the hay in that country was contaminayed by radioactive.Isotope remains, how long did the famers need to.Wait to use this hay
Answer:
the question is incomplete, so I looked for a similar one:
After the release of radioactive material into the atmosphere from a nuclear power plant, the hay was contaminated by iodine 131 ( half-life, 8 days). If it is all right to feed the hay to cows when 10% of the iodine 131 remains, how long did the farmers need to wait to use this hay?
iodine's half life (we are given x, we need to find b):
0.5A₀ = A₀eᵇˣ
x = 8 days
we eliminate A₀ from both sides
0.5 = eᵇ⁸
ln 0.5 = ln eᵇ⁸
-0.69315 = b8
b = -0.69315 / 8 = -0.08664
since the farmers need to wait until only 10% of the iodine remains (we already calculated b, now we need to find x):
0.1A₀ = A₀eᵇˣ
0.1 = eᵇˣ
ln 0.1 = bx
where b = -0.08664
x = ln 0.1 / -0.08664 = -2.302585 / -0.08664 = 26.58 days

QUICK HELP ME! seven children in a family like apples, 6 children like bananas, and 5 children like peaches. four children like both apples and bananas, 3 children like both apples and peaches, 2 children like both peaches and bananas, and one child likes all three. how many children are in the family
9514 1404 393
Answer:
10
Step-by-step explanation:
1 child likes all three
4 like apples and bananas, so 4-1 = 3 like apples and bananas only
3 like apples and peaches, so 3-1 = 2 like apples and peaches only
2 like peaches and bananas, so 2-1 = 1 like peaches and bananas only
7 like apples, but 3+2+1 like one or more other fruits, so 1 likes apples only
6 like bananas, but 3+1+1 like one or more other fruits, so 1 likes bananas only
5 like peaches, but 2+1+1 like one or more other fruits, so 1 likes peaches only
__
1 + 1 + 1 = 3 like exactly 1 fruit;
3 + 2 + 1 = 6 like exactly 2 fruits;
1 likes exactly 3 fruits.
The total number of children is 3 + 6 + 1 = 10.
Assuming all the referenced children are in the family, there are 10 children in the family.

Question 2(Multiple Choice Worth 5 points) (04.01)The Boardman family walked two over five of a mile in two over seven of an hour. What is their unit rate in miles per hour?
Answer:
The unit rate in miles per hour = 1.4 miles/hr
Step-by-step explanation:
Given that:
Distance walked by Boardman family = Two over five of a mile = [tex]\frac{2}{5}\ miles[/tex]
Time taken by Boardman family = Two over seven of an hour = [tex]\frac{2}{7}\ hour[/tex]
To find:
The unit rate in the miles per hour = ?
Solution:
Formula for the rate or the speed can be given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Putting the values:
[tex]\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}[/tex]
So, the unit rate in miles per hour = 1.4 miles/hr
