The scale dimensions of the rooms on the blueprint using a scale of 1/4 inch = 1 foot are calculated by converting feet to inches, then dividing by the scale ratio (0.25 inches per foot) to find each room's dimensions in inches on the blueprint.
To calculate the scale dimensions of the rooms on the blueprint, you will use the given scale of 1/4 inch = 1 foot. This means for every 1/4 inch on the blueprint, it represents 1 foot in actual size.
Step-by-Step Calculation for Each Room
Convert the scale into a ratio that can be used for calculations (1/4 inch / 1 foot or 0.25 inches / 12 inches since there are 12 inches in a foot).
Calculate the scale dimension for each room by dividing the actual dimension in inches by the scale ratio.
For each room, ensure to convert feet to inches first (1 foot = 12 inches) and then apply the scale.
Bedroom: 10 feet 6 inches is (10 * 12) + 6 = 126 inches, 11 feet is (11 * 12) = 132 inches. Scale dimensions: (126 inches / 48) by (132 inches / 48) equals 2.625 inches by 2.750 inches.Living room: 25 feet is (25 * 12) = 300 inches, 18 feet 8 inches is (18 * 12) + 8 = 224 inches. Scale dimensions: (300 inches / 48) by (224 inches / 48) equals 6.250 inches by 4.667 inches.Kitchen: 13 feet 6 inches is (13 * 12) + 6 = 162 inches, 8 feet is (8 * 12) = 96 inches. Scale dimensions: (162 inches / 48) by (96 inches / 48) equals 3.375 inches by 2.000 inches.Dining room: 12 feet is (12 * 12) = 144 inches, 10 feet is (10 * 12) = 120 inches. Scale dimensions: (144 inches / 48) by (120 inches / 48) equals 3.000 inches by 2.500 inches.Below is the scale dimensions for each room to the nearest thousandth:
Bedroom: 2.625 inches by 2.750 inchesLiving room: 6.250 inches by 4.667 inchesKitchen: 3.375 inches by 2.000 inchesDining room: 3.000 inches by 2.500 inchesWhich is the graph of f(x)= square root of x

A person invested $7,200 in an account growing rate allowing money to double every 8 years. How much money would be in the account after 19 years, to the nearest dollar?
After 19 years, the final amount is $29,936.93, to the nearest dollar.
What is the formula for exponential growth?The formula for exponential growth:
[tex]final amount = initial amount * (rate)^(number of time periods)[/tex]
In this case, the initial amount is $7,200, the rate is 2 (since the money doubles every 8 years), and the number of time periods is 19/8=2.375 (since 19 years is 2.375 times the 8-year doubling period). Plugging these values into the formula, we get:
final amount = $7,200 * 2^2.375
The final amount is $29,936.93, to the nearest dollar.

pls help me with this one question
The following sequence is an arithmetic sequence what comes next ? 7,___,17
Since this is an arithmetic sequence, you can conclude that the addition to the number is constant.
Let x = the number asked
k = constant number added to the sequence
7 + k = x
x + k = 17
Solve the system of equation:
7 + k + k = 17
7 + 2k = 17
2k = 10
k = 5
Therefore, the missing number is 12 (7 + 5).

Calculate the difference 12.0875 – 7.50 using significant digits.
A. 4.5
B. 4.587
C. 4.59
D. 4.6
C. 4.59
Step-by-step explanation:Significant digits are digits expressing precision of a measurement. Non-zero digits are always significant but zeroes can be either included or ignored. For instance, zeroes that comes before other digits aren't significant. For example 0.058 has two significant digits. In this exercise, we have two numbers:
12.0875
7.50
The number 12.0875 has five significant digits while 7.50 has three significant digits. If we add or subtract two numbers, the least number of decimal places (that isn't the same as significant digits) in any of the two numbers must be the same as the number of decimal places in the result. Hence, for 12.0875 we have four decimal places and for 7.50 we have two decimal places. Therefore, the result must have two decimal places:
12.0875 - 7.50 = 4.59

Answer:
Step-by-step explanation:
We will make a substitution to make our work easier (when we get there). We also need to know that
[tex]i^2=-1[/tex]
We will use that as another substitution. First, let's make the job of factoring a bit easier. Here's the first substitution. We will let
[tex]x^4=u^2[/tex]
Therefore,
[tex]x^2=u[/tex]
Now we will write the polynomial in terms of u instead of x:
[tex]f(x)=u^2+21u-100[/tex]
Solve for the values of u by setting the polynomial equal to 0 and factoring. When you factor, you will get:
[tex](u+25)(u-4)[/tex]
But don't forget that
[tex]x^2=u[/tex]
so we have to put those back in now:
[tex](x^2+25)(x^2-4)=0[/tex]
By the Zero Product Property, either
[tex]x^2+25=0[/tex] or
[tex]x^2-4=0[/tex]
We will factor the first term. Solving for x-squared gives us:
[tex]x^2=-25[/tex] and
x = ±√-25
which simplifies down to
x = ±√-1 × 25
we can sub in an i-squared for the -1:
x = ±√[tex]i^2*25[/tex]
The square root of i-squared is "i" and the square root of 25 is 5, so
x = ±5i
The next one is a bit easier. If
[tex]x^2=4[/tex], then
x = ±2
You can see you have 4 solutions. But you knew that already, since this is a 4th degree polynomial. The types of solutions are: 2 real, 2 imaginary

Which equation represents a direct variation?
y = 2x
y = x + 4
y =1/2x
y = 3/x
Answer:
A. [tex]y=2x[/tex]
Step-by-step explanation:
We are asked to find the equation that represents a direct variation.
We know that a direct variation is in form [tex]y=kx[/tex], where y is directly proportional to x and k is constant of variation.
Upon looking at our given choices, we can see that equation [tex]y=2x[/tex] represents direct variation, where [tex]k=2[/tex].
Therefore, option A is the correct choice.

Your friend wants to borrow $1,137.45 from you to pay off a credit card that charges a 14.7% APR. You agree to the loan but require your friend to pay you interest of 3.6% APR on the loan and your friend agrees.
Your friend pays you $200.00 at the end of the first month. How much goes toward the principal?
The amount that goes into the principal when friend pays you $200.00 at the end of the first month is $296.56.
How to calculate the amount?The first interest will be:
= 1137.45 × (0.036/12)
= 3.41
The amount owed at the month end will be:
= 1137.45 + 3.41
= 1140.86
The new balance after 200 payment will be:
= 1140.86 - 200
= 940.86
Therefore, the reduction in principal will be:
= 1137.45 - 940.86
= 196.59

The population of wild horses on a wildlife refuge decreased from 110 to 99 in a year. If this trend were to continue, what exponential equation could be used to predict the horse population in the future?
y = 110(1.1)^x
y = 99(0.9)^x
y = 99(1.1)^x
y = 110(0.9)^x,
The exponential equation for this situation is y = 110(0.9) ^x. This is because 110 is the principal or the initial number of horses and y is the resultant population after a certain number of years X with a rate of 0.9. Note that the rate is less than 1 which means that the population is decreasing as time goes by.

To solve this word problem, set up the equation (1/5) x + (1/10) x = 42 and solve for x. The team scored 140 points.
Explanation:To solve this word problem, we can start by letting the total number of points scored by the team be represented by 'x'. Since Michaela scored one-fifth of the team's points, her score can be represented as (1/5)x. Similarly, Aleah's score can be represented as (1/10)x. Together, their scores add up to 42 points, so we can set up the equation:
(1/5)x + (1/10)x = 42
To simplify the equation, we can find a common denominator of 10:
(2/10) x + (1/10) x = 42
Combining like terms, we get:
(3/10) x = 42
To isolate x, we can multiply both sides of the equation by 10/3:
x = 42 * (10/3)
Simplifying further, we get:
x = 140
Therefore, the team scored 140 points.
