Step-by-step explanation:

1 2/7=9/7

2 1/3=7/3

--------------

9/7+7/3x+3/14+x=9

18/14+3/14+7/3x+3/3x=9

21/14+10/3x=9

10/3x=9-21/14

10/3x=9-3/2

10/3x=18/2-3/2

What is the bill of a house that consumed 1000 units of electricity,if the first 100 units are charged $10.00 per unit and the remaining units at $5.00 per unit?

Answers

Answer:

$14500

Step-by-step explanation:

$10 per unit means 1 unit is equivalent to 10 dollars.

∴Unit multiplier = $\frac{10 dollars}{unit}$

$5 per unit means 1 unit is equivalent to 5 dollars

∴Unit multiplier = $\frac{5 dollars}{unit}$

Remaining units = 1000 - 100 = 900 units

The unit multipliers are arranged in such a way that the "units” in the numerator and denominator will cancel each other out leaving us with “dollars” in the numerator. Our answer should be expressed in dollars
since the question requires us to calculate the bill

Bill of the House = Charge of first 100 units + Charge of remaining units

= (1000 units)($\frac{10dollars}{unit}$) + [(900)units][$\frac{5dollars}{unit}$]

= $10000 + $4500

= $14500

Jason jumped off a cliff into the ocean in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function h ( t ) = − 16 t 2 + 16 t + 480 h(t)=−16t 2 +16t+480, where t is the time in seconds and h is the height in feet. What was Jason's initial height?

Answers

Jason's initial height was 480 feet based on calculation using the given function and time.

The given function h(t) = -16t^2 + 16t + 480 models the height of Jason, who jumped off a cliff into the ocean in Acapulco while on vacation with his friends. To find his initial height, we need to find the value of h(0), which represents his height at time t = 0 seconds (i.e., when he jumped off the cliff). Substituting t = 0 in the given function, we get h(0) = 480. Therefore, Jason's initial height was 480 feet.

Knowing Jason's initial height is important in understanding his overall motion and the total distance he fell. It also helps to understand his velocity and acceleration during the fall. This information is useful for safety reasons and to study the mechanics of free fall. Additionally, this problem demonstrates the application of quadratic functions to real-life situations, such as modeling the trajectory of an object in motion.

Nelson lands 4650 on 2% interest rate. He plans to pay this after 2 months. What will the total principal and interest payment be?

Answers

The total principal and interest payment that Nelson will have to pay after 2 months is $4665.50.

To calculate the total principal and interest payment, we need to determine the interest amount and add it to the principal.

First, let's find the interest amount:

Interest = Principal x Interest Rate x Time

Given:

Principal = $4650

Interest Rate = 2% per year

Time = 2 months

Since the interest rate is given on an annual basis, we need to convert the time from months to years. There are 12 months in a year, so 2 months is equivalent to 2/12 = 1/6 years.

Interest = $4650 x 0.02 x (1/6) = $15.50

Now, we can calculate the total principal and interest payment:

Total Payment = Principal + Interest

Total Payment = $4650 + $15.50 = $4665.50

what is expression ?

An expression in mathematics is a collection of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, division, exponentiation, and so on) that express a quantity or value. Expressions might be as basic as "3 + 4" or as complex as "(3x2 - 2) / (x + 1)". They may also contain functions like "sin(x)" or "log(y)". Expressions can be evaluated by substituting values for the variables and performing the mathematical operations in the order specified. If x = 2, for example, the formula "3x + 5" equals 3(2) + 5 = 11. Expressions are commonly used in mathematics to describe real-world situations, construct equations, and simplify complex mathematical issues.

Add the class width to the lower class limit and subtract one to find the higher class limit.

So,

Lower Class Limit + Class Width - 1 = 12 + 9 - 1 = 20

As a result, the upper class limit is 20.

Both groups have a similar spread, with most of the dots clustered around the middle of the distribution. However, there are some differences in the tails of the distribution that affect the measures of spread.

For Group A, the lowest score is 41, and the highest score is 50. The interquartile range (IQR), which is the range containing 50% of the scores, is approximately from 45 to 48. The range, which is the difference between the highest and lowest scores, is 9.

For Group B, the lowest score is 41, and the highest score is 50. The interquartile range (IQR) is approximately from 43 to 49. The range is also 9.

Square roots of negative numbers are imaginary. This is asking for the difference of two complex numbers. A suitable calculator can show you what that is.

simplify radicals

We know that √(-1) ≜ i. This means the radicals can be simplified to ...

$\sqrt{-81}=\sqrt{9^2(-1)}=9\sqrt{-1}=9i\\\\\sqrt{-9}=\sqrt{3^2(-1)}=3\sqrt{-1}=3i$

So the expression becomes ...

Like terms can be combined in the usual way. For the purpose here, i can be treated as though it were a variable.
