Step-by-step explanation:
“To find 623, I can just take the value of 613 then either multiply it by 12 or divide it by 2.” Do you agree with her? Explain why or why not.
Step-by-step explanation:
613 and 623 are very close values.
multiplying by 12 or a division by 2 changes the starting value drastically.
so, this cannot be right.
and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.
so, therefore, even without actually calculating the numbers, the statement is proven false.
The price of an item yesterday was $130. Today, the price rose to $299. Find the percentage increase.
Answer:
130%
Step-by-step explanation:
Use the formula for percent change: difference = % * original price
To find the difference, you have to do 299 - 130, which is 169.
The original price is $130 because this is the price before it rose to $299.
Now, you have the equation 169 = % * 130.
We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.
130%
Step-by-step explanation:
Yesterday = $130.
Today = $299 .
((final price - initial price)/(initial price)) × 100%
= (($299 - $130)/$130) × 100%
= ($169/$130) × 100%
= $1,3 × 100%
= 1,3 × 100%
= 130%

Answer:
309 meters
Step-by-step explanation:
The scale is 3mm : 2m so you can set up two fractions and solve for x.
[tex]\frac{3mm}{2m} =\frac{x}{206m}[/tex]
since every two meters is 3 mm in the drawing, divide 206 by 2 and get 103
now, multiply 103 by 3 to get 309
309 mm in the drawing

Sonia works at a bakery. The function f(x) represents the amount of money Sonia earns per loaf, where x is the number of loaves she makes. The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 8^2 +4
g of x equals the square root of the quantity 2 x cubed
Answer:
[tex] f(x)=8x^2+4\\ g(x)=\sqrt{2x^3}\\ f(g(x))=8((\sqrt{2x^3})^2)+4\\=16x^3+4\\=4(4x^3+1)[/tex]
The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The functions are given below.
f(x) = 8x² + 4
g(x) = √(2x³)
The function f(g(x)) is calculated as,
f(g(x)) = 8[√(2x³)]² + 4
f(g(x)) = 8[√(2x³)]² + 4
f(g(x)) = 16x³ + 4
f(g(x)) = 4(4x³ + 1)
The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

Jackson deposits $4,200 in a savings account that pays 3.5% annual interest.What is the total value of the account after 10 years
Answer:
5924, 51
Step-by-step explanation:
X = 4200(1.035)^10
And put it in a calculator
The total value of the account after 10 years is $5,924.52.
Given that,
The deposited amount is $4,200.The rate of interest is 3.5%.And, the time period is 10 years.Based on the above information, the calculation is as follows:
[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]
= $5,924.52
Therefore we can conclude that the total value of the account after 10 years is $5,924.52.

Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.
=======================================================
Work Shown:
Distance = rate*time
rate = distance/time
----------------
For Sarah, she runs 324 m in 61.3 seconds. Her speed is:
rate = distance/time
rate = (324 m)/(61.3 sec)
rate = (324/61.3) meters per second
rate = 5.28548 meters per second approximately
----------------
Repeat the same set of steps for Emily
rate = distance/time
rate = (324 m)/(60.4 sec)
rate = (324/60.4) meters per second
rate = 5.36423 meters per second approximately
----------------
The last thing to do is subtract the results we got
5.36423 - 5.28548 = 0.07875
This then rounds to 0.08 meters per second when rounding to two decimal places.

A bank offers 2% simple interest per year. A woman opens an account with deposit of 900 pounds. She closes the account 2 years later. How much will she withdraw.
simple interest formulae = PRT/100
where
p stands for percentage (2%)
r stands for rate ( 900)
t stands for time (2 years )
2×900×2/100
=3600/100
=36
Deposit interest
Level : SHS Keyword : deposit interest, simple interestDeposit Interest in 2 years
= D × i × T/365 days
= 900 pounds × 2% × (365 × 2 years)/365 days
= 900 pounds × 0.02 × 730 days/465 days
= 900 pounds × 0.02 × 2
= 36 pounds
Her Deposit in 2 years
= 900 pounds + 36 pounds
= 936 pounds
So, her deposit if she will withdraw is 936 pounds
