Answer:
19 years approx
Step-by-step explanation:
Given dta
P= $9000
r= 6.5%
A= $31100
Calculate time, solve for t
t = ln(A/P) / r
substitute
t= ln(31100/9000)/0.06.5
t= ln(3.45)/0.06.5
t= 1.23/ 0.065
t= 18.92
Hence the time is 19 years approx

Solve the simultaneous equations
y = 2x^2
y = 3x + 14
Answer:
x = -2
And, x = 7 ÷ 2
Step-by-step explanation:
Given that
y = 2x^2
y = 3x + 14
Now equate these two above equations
2x^2 = 3x + 14
2x^2 - 3x - 14
2x^2 -7x + 4x - 14
x(2x - 7) + 2(2x - 7)
(x + 2) (2x - 7)
So it can be x = -2
And, x = 7 ÷ 2

Answer:
440h is the expression. When 3 1/4 is evaluated you get 1,430 calories burned.
Step-by-step explanation:
440 represents the number of calories she burns per hour. To represent the hour, we place a variable which is h. After we write the expression, we substitute 3 1/4 for h. When I did this, I turned 3 1/4 into an improper fraction, which was 13/4, and then divided 13 by 4 to get 3.25
Multiple 3.25 by 440 to get an answer of 1,430 calories burned.
Hope this helps :)
Maria bought g gallons of gasoline for $3.95 per gallon and c cans of oil for $4.45 per can. a. What expression can be used to determine the total amount Maria spent on gasoline and oil? b. If she bought 8.6 gallons of gasoline and 9 cans of oil, how much did she spend in all? a. Choose an expression that represents the amount that Maria spent in all.
Answer:
a.) Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )
b.) Total amount spent by Maria = $ 74.02
Step-by-step explanation:
As given,
Cost of gasoline = $ 3.95 gallon
Cost of oil per can = $ 4.45
Also given,
Maria bought g gallons of gasoline and c cans of oil
⇒ Total cost of g gallons of gasoline = g×3.95 = $3.95g
Total cost of c cans of oil = c×4.45 = $4.45c
Now,
a.)
Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )
b.)
As given ,
Maria buy gasoline , g = 8.6 gallons
Maria buy cans of oil , c = 6
So,
Total amount spent = $ 3.95(8.6) + 4.45(9)
= $ 33.97 + 40.05 = $ 74.02
⇒Total amount spent by Maria = $ 74.02
Construct the bisector of the following figures
Answer:
In these lessons, we will learn
how to construct an angle bisector of a given angle.
how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.
An angle bisector is a straight line that divides the angle into two equal parts.
Example: Construct an angle bisector for the following angle:
Solution:
Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).
Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.
construct angle bisector
Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.
construct angle bisector
The steps to construct an angle bisector can be summarized as follows:
1. From the vertex, draw an arc across both rays of the angle.
2. From each arc intersection draw another pair of arcs that intersect each other.
3. Draw a line from the vertex to the intersection point to form the angle bisector.

Step-by-step explanation:
a restaurant customer left $1.80 as a tip. The tax was 8% and the tip was 20% of the after tax cost
Divide tip by portion of bill:
1.80/0.20 = 9.00
The total bill before the tip was $9.00
Divide total bill by 1+ sales tax rate:
9.00 / 1.08 = 8.33
The bill before tax was $8.33

19 3/7 - 12 6/7
Plz show how u got your answer
Answer:
16 4/7
Step-by-step explanation:
First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

The ratio of lemons to lime in a punch is 6:4. If there are 35 fruit in the punch, how many of them are lemons?
Answer:
21 lemons
Step-by-step explanation:
If the ratio is 6:4, the ratio is also equal to 3:2. This means, for every 3 lemons, there are two limes.
So, if there are 35 lemons and limes in total, we would have 21 lemons and 14 limes.

A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?
Answer:
[tex]y-(9)=(-8)(x-8)\\[/tex]
Step-by-step explanation:
[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]
Step one: Find the slope (m)
[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]
Step two: Plug your known values into the point-slope equation
[tex]m=-8\\y_1=9\\x_1=8\\[/tex]
Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(9)=(-8)(x-8)\\[/tex]
If you want to convert point-slope form to general form, isolate for y.
[tex]y-9=-8x+64\\y=-8x+73[/tex]
