Answer: 6.3x + 2.885
Step-by-step explanation:
Since there is only one factor of x, we cannot simplify x.
We can simplify the constants though.
6.3x + (-7.015 + 9.9)
= 6.3x + 2.885

2.4 feet1700 pigs What will be the height of the 5th bounce?Generally, For the first problem, the height of the 5th bounce can be calculated by plugging in 5 for x in the function
f(x) = 20 (0.6)^x:
f(5) = 20 (0.6)^5
= 20 (0.12)
= 2.4 feet
What will be the population in 12 years?For the second problem, the population in 12 years can be calculated by plugging in 12 for x in the function f(x) = 1000 (1.04)^x:
f(12) = 1000 (1.04)^12

Kendra owns a restaurant. She charges $1.50 for 2 eggs and one piece of toast and $0.90 for one egg and one piece of toast. Write a system of equations that can be used to
determine how much she charges for each egg and each piece of toast.
Enter your answer in the space below.
√x
Answer:
Each egg costs $0.60
Each piece of toast costs $0.30
Step-by-step explanation:
Let's assume that the cost of a single egg is E
And the price of a toast as T
Kendra charges $1.50 for one toast and two eggs
The equation above will be
2E + T = $1.50
And the other equation is
E + T = $0.90
For the second equation, we make E the subject of the formula
E = 0.90 - T
Now substitute for this in equation 1
2E + T = 1.50
It will now be 2(0.90 - T) + T = 1.50
1.80 - 2T + T = 1.50
T= $0.30
price of one toast is $0.30
And now, for the price of an egg, we substitute T = 0.30 in the equation
E= $0.60
Pens are sold in a pack of 10 for 95 krona ( Swedish money ). If the price is reduced by 30%, what is new cost per pen
The new cost per pen based on the information is $6.650.
What is the cost per pen?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.
In this case, the pens are sold in a pack of 10 for 95 krona and the price is reduced by 30%, the new price will be:
= 95 - (30% × 95).
= 95 - 28.5
= $66.50
The new cost for every pen will be:
= $66.50 / 10
= $6.650

the area of the triangle formed by the x and y intercepts of the parabola y=0.5(x-3)(x+k) is equal to 1.5 square units. find all possible values of k.
The possible values of k are -0.56, -3.56, -2 and -1.
Find all possible values of k ?We have the equation of the parabola, y = 0.5 (x- 3 ) ( x+ k)
Substituting x=0, we get that i.e. y =0.5 * (-3) * k -1.5k
So, the y-intercept is (0,-1.5k).
Thus, the height of the triangle becomes |-1.5k| = 1.5k
Again, substituting y=0, 0 = 0.5 (x-3) (x+k) i.e. i.e. x0=(x-3) (x+k)=3 and x=-k
So, the x-intercepts are (3,0) and (-k,0).
Thus, the base of the triangle is 3+k if k>-3 or -3-k if k<-3.
As, area of a triangle = 1/2 * (base )* (height )
Substituting the values, we get,
1.5=1/2 *(3+k)*(1.5k)
i.e.3= 4.5 k + 1.5k ²
i.e. k = -0.56 and k = -3.56
or
1.5=1/2* (-3-k )*(1.5k)
i.e.
3 = -4.5 k - 1.5²
i.e. k = -2 and k = -1.
Thus, the possible values of k are -0.56, -3.56, -2 and -1.

What is an explanation of the interest rate?
An interest rate informs you of how much borrowing will cost you and how much saving will pay off.
Therefore, the interest rate is the amount you pay for borrowing money and is expressed as a percentage of the entire loan amount if you are a borrower.
Amount distributed as dividends = $15000
Total Preferred dividend to be paid = $37500
But Total Preferred dividend paid/avaiable = $15000
dividend per share(P.S) = $0.60 **(15000 / 25000shares)
Since the preferred stock cumulative dividend to be paid in Next year due to less payment in current year would be = $22500 or $0.90 per share

Which equation is equivalent to the formula d = rt? r equals d over t r = dt t equals r over d t = dr
The equation is equivalent to the r = d/t.
There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity. If there is no 'equal to' symbol in the statement, it means it is not an equation. It will be considered as an expression.
We have to find which equation is equivalent to the formula d = rt.
Formula given: d = rt
Divide both sides by t
d/t = rt / t
d/t = r

The measures of two vertical angles are given by the expressions (x+16)° and (2x - 3).
Find the value of x . What is the measure of each angle?
Answer:
see explanation
Step-by-step explanation:
vertical angles are congruent , then
2x - 3 = x + 16 ( subtract x from both sides )
x - 3 = 16 ( add 3 to both sides )
x = 19
Then
x + 16 = 19 + 16 = 35°
since the angles are congruent , then
the measure of each angle is 35°

Using the interest rate formula, we know that the simple interest rate on the loan is 5.75%.
What is the simple interest rate?Simple interest is calculated by multiplying the principal by the time, interest rate, and time period.
"Simple Interest = Principal x Interest Rate x Time" is the written formula.
The simplest method for computing interest.
So, the interest rate on the loan is:
Formula to be used: I = p*r*t
Where I am the interest, p is the principal amount, r stand for rates and t stands for time.
I = p*r*t
3450 = 3000*2*r
3450/6000 = r
r = 0.575%
That is a 5.75% interest rate
Therefore, using the interest rate formula, we know that the simple interest rate on the loan is of 5.75%.

Anais goes to the store to get granola bars 1 pack of 100 granola bars is $8.67.
Another pack of granola bars is 50 granola bars for $5.48. Which is the better buy?
The better option is to buy the Granola bar.
What is a unit value?
When the expenditures or value of production of an item is divided by the quantity, the result is known as a unit value. The unit value of a set of homogeneous products is the total value of the purchases/sales divided by the sum of the quantities.
To determine which is the better buy, you need to compare the price per granola bar for each option. To do this, you can divide the price of each pack by the number of granola bars it contains.
For the first pack of 100 granola bars, the price per granola bar is $8.67 / 100 granola bars = $0.09 per granola bar.
For the second pack of 50 granola bars, the price per granola bar is $5.48 / 50 granola bars = $0.11 per granola bar.
Since the price per granola bar is lower for the first pack, it is the better buy. You would save money by purchasing the first pack of 100 granola bars instead of the second pack of 50 granola bars.
Hence, the better option is to buy the Granola bar.

Estimate −74.41- 55.816 by first rounding each number to the nearest whole number.
PLEASE HELP!!!
Answer: -130.
Step-by-step explanation: To round −74.41 to the nearest whole number, we look at the tens place, which is the digit 4 in the number −74.41. Since 4 is less than 5, we round down to the previous whole number, which is −74.
To round 55.816 to the nearest whole number, we look at the tens place, which is the digit 8 in the number 55.816. Since 8 is greater than or equal to 5, we round up to the next whole number, which is 56.
Now that we have rounded both numbers to the nearest whole number, we can easily subtract them to get an approximate answer:
-74 - 56 = -130
Therefore, an approximate solution to −74.41- 55.816 is -130.
