The perimeter of the figure to the right, made up of identical squares, is equal to 56 cm. What is the area of the figure?
The area of the square will be 196cm².
How to calculate the area?It should be noted that the perimeter of a square is the addition of all its sides. Therefore, the length of the side will be:
= 56/4
= 14
Therefore, the area of the figure will be:
= 14²
= 14 × 14
= 196cm²

If $300 is invested at a rate of 5% per year and is compounded quarterly, how much will the investment be worth in 20 years?
Use the compound interest formula A equals P times the quantity 1 plus r divided by n end quantity raised to the power of n times t..
$810.45
$515.28
$384.61
$109.67
Answer:
(a) $810.45
Step-by-step explanation:
You want the value of an investment of $300 earning 5% interest compounded quarterly for 20 years.
Compound interestThe compound interest formula tells you the value is ...
A = P(1 +r/n)^(nt)
where P = 300, r = 0.05, n = 4, t = 20.
Using the given parameters in the given equation, you find the account value to be ...
A = $300(1 +0.05/4)^(4·20) ≈ $810.45
__
Additional comment
The "rule of 72" tells you the account value will approximately double in a number of years equal to 72 divided by the interest rate percentage: 72/5 = 14.4 years. After 20 years, it will be worth more than that doubled amount, $600. This only leaves one reasonable answer choice.

Structured Observation is simply refered to as method or technique often used for data collection. it is said to rely on wide or explicit rules for observing, categorizing, and recording behaviour of all types.There is direct observation of behaviour of which is not often used due to the fact that there is limited access to some social spaces and difficulty in capturing some behaviours. It is made up of smaller sample sizes.From the above we can therefore say that the answer The example of structured observation is when a new employee sits beside a veteran employee to see what types of situations occur during a normal work is correct

These are Literal Equations. Solve for g: aeg=10.
Answer:
g = 10/(ae)
Step-by-step explanation:
When variables are shown like that, in reality they are multiplied:
aeg = 10 is the same as a * e * g = 10
Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Simply divide variables a & e from both sides:
(aeg)/ae = (10)/ae
g = 10/ae
g = 10/(ae) is your answer.

⇒ a₂ = 50 ÷ 2
⇒ a₂ = 25
a₃ = a₂ ÷ 2
⇒ a₃ = 25 ÷ 2
⇒ a₃ = 12.5
a₄ = a₃ ÷ 2
⇒ a₄ = 12.5 ÷ 2

The function h(x) = x^3 + 2x^2 - 9x - 18 can be factored to
h(x) = (x + 2)(x + 3)(x - 3). Describe the intercepts of this function
The function h(x) = x^3 + 2x^2 - 9x - 18 can be factored as (x + 2)(x + 3)(x - 3), which reveals the intercepts of the function.
To find the intercepts of the function h(x), we set h(x) equal to zero and solve for x. The intercepts occur when the function crosses the x-axis, meaning the value of h(x) is zero at those points. By factoring h(x) as (x + 2)(x + 3)(x - 3), we can see that the intercepts are at x = -2, x = -3, and x = 3. This means the graph intersects of the function h(x) crosses the x-axis at these points. At x = -2, x = -3, and x = 3, the function h(x) has intercepts with y = 0, indicating the points where the graph intersects the x-axis.

How do right an log form equation
Below is how to write an equation in logarithmic form
How to write a log form equation?To write an equation in logarithmic form, we need to convert it from its exponential form.
An exponential equation has the form:
aᵇ = c
where a is the base, b is the exponent, and c is the result.
To convert this equation to logarithmic form, we can write:
logₐ(c) = logₐ(aᵇ) (Taking logarithm of both side)
logₐ(c) = b logₐ(a) (logₐ(a) = 1)
logₐ(c) = b
where logₐ represents the logarithm to the base a. This equation tells us that the exponent b is the logarithm of c to the base a.
For example, the exponential equation 2³ = 8 can be written in logarithmic form as:
log₂(8) = log₂(2³) = 3
This equation tells us that the logarithm of 8 to the base 2 is equal to 3, which is the exponent that we need to raise 2 to in order to get 8.

At the end of a party, 3/4 cup of dip is left. Jim divides 4/7 of the leftover dip equally between 2 friends. How much dip does each friend get?
Answer:
First, we need to find the amount of dip that was divided amount the two friends.
We know that it is 4/7 of the left dip
therefore:
amount divided among the two friends = (4/7) x (3/4) = 3/7 of the original amount of dip.
This amount is divided among two friends,
therefore:
amount that each friend gets = (3/7) / (2) = 3/14 = 0.2 of the amount of dip

The alternate hypothesis states that the distribution of motivations differs from the old survey. The critical value and rejection region need to be determined to test this hypothesis.
To test if there has been a change in the distribution of motivations, the null hypothesis assumes that the distribution remains the same as in the old survey, while the alternate hypothesis suggests a difference. In this case, the alternate hypothesis is that the distribution of motivations differs from the old survey.
To determine the critical value and rejection region, the significance level (α) needs to be specified. In this case, α is given as -0.005. However, it seems there may be some confusion in the provided information, as a negative significance level is not possible. The significance level should typically be a positive value between 0 and 1.
Without a valid significance level, it is not possible to determine the critical value and rejection region for hypothesis testing. The critical value is typically obtained from a statistical table or calculated based on the significance level and the degrees of freedom.
In conclusion, without a valid significance level, it is not possible to determine the critical value and rejection region to test the hypothesis regarding the change in the distribution of motivations for credit card usage among college students.

Isabelle bought some stationery. 1/3 of them were pencils. 5/8 of the remainder were erasers and the rest were rulers. The cost of the stationery is - a Pencil: $1.20, an eraser: $1 and a ruler: $0.50. She spent a total of 169.50 on all stationery. How much more did she spend on erasers than rulers.
Answer:
Isabelle spent $52.50 more on Erasers than rulers.
Step-by-step explanation:
Step 1
Find the quantity of each stationery bought in fraction
Let us represent the total fraction of what Isabelle bought as: x
1/3x = quantity of pencils bought
5/8 of the remainder = quantity of erasers bought
The remainder = x - 1/3x = 2/3x
5/8 of 2/3x = 5/8 × 2/3x = 5/12x
Hence, 5/12x = quantity of erasers bought
The rest is rulers
1 - (1/3 + 5/12)
1 - (4 + 5/12)
1 - 9/12
1 - 3/4
= 1/4x
Hence, 1/4 = quantity of rulers bought.
Step 2
We find the number of stationeries that Isabelle bought.
The cost of the stationery is
a Pencil: $1.20
an eraser: $1
a ruler: $0.50.
Total amount spent on stationery = 169.50
We have this equation
1.20 × 1/3x + 1 × 5/12x + 0.50 × 1/4x = 169.50
0.4x + 0.4166666667x + 0.125x =
169.50
0.9416666667x = 169.50
x = 169.50 /0.9416666667
x = 179.99999999
Approximately , the number of stationeries that Isabelle bought = x = 180
Step 3
Find the number and the amount spent on each stationery that Isabelle bought
a) i) Quantity of pencils bought = 1/3 x
x = 180
= 1/3 × 180
= 60 pencils
ii) Amount spent on pencils
If 1 pencil = $1.20
60 pencils =
60 × 1.20 = $72
b) i) Quantity of Erasers bought = 5/12x
x = 180
= 5/12 × 180
= 75 pencils
ii) Amount spent on Eraser
If 1 pencil = $1
75 pencils =
75 × 1 = $75
c) i) Quantity of rulers bought = 1/4 x
x = 180
= 1/4 × 180
= 45 pencils
ii) Amount spent on pencils
If 1 pencil = $0.50
45 pencils =
45 × 0.50 = $22.50
Step 4
We were asked to calculate how much more did she spend on erasers than rulers.
In step 3, the amount spent on Erasers = $75
the amount spent on ruler = $22.5
The difference in the amount spent = $75 - $22.5
= $52.5
Therefore, Isabelle spent $52.50 more on Erasers than rulers.
