Really need help on this one!
Answers
x = (4-2)/3 = 2/3
y = (5-6)/2 = -1/2
x + y = 2/3 + (-1/2)
2/3 - 1/2
LCM (least common multiple) is 6 so just cross multiply
4/6 - 3/6 = 1/6

Suppose you invest $800 into an annuity account that pays 7% annual interest, compounded continuously. How much will you have in the account in 10 years? F(t) = ae^rt
Answers
Answer:
1611.00
Step-by-step explanation:
You have $1611.00 in the account in 10 years. The correct option is B.
What is continuous compound interest?Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.
Formula of continuous compound interest rate;
F(t) = a(e[tex])^{rt}[/tex]
, where a is the principal amount, r is the interest rate and t is the time period.
Given:
You invest $800 into an annuity account that pays 7% annual interest, compounded continuously.
And the formula is given by:
F(t) = a(e[tex])^{rt}[/tex]
According to the question,
Investment a = $800
Time period = 10 years.
And the interest rate r = 7%
Converting interest rate into decimals,
r = 0.07
Substituting all the values top the formula,
F(t) = a(e[tex])^{rt}[/tex]
F(t) = (800)(e[tex])^{(0.07)(10)}[/tex]
F(t) = (800)(e[tex])^{(0.7)}[/tex]
F(t) = 1611
F(t) = $1611.00
Therefore, you have $1611.00 in account.

2) Adjacent (but not a linear pair)
3) Complementary Angles
4) Vertical angles
Step-by-step explanation:
1st pair of angles are linear because they sum to 180 and are on the same line
2nd pair of angles are adjacent but not linear because they're not on a line
3rd pair of angles are complementary because they're neighboring a 90° angle and the three angles share the same line.
4th pair of angles are vertical because they're across from each other.
Answers:
Linear PairAdjacent (but not a linear pair)ComplementaryVertical AnglesThe answers are given from top to bottom in that exact order.
=======================================================
Explanations:
Angles AOB and DOB are considered a linear pair because they are adjacent and supplementary. They are adjacent because they share a common wall so to speak. That wall being ray OB. They are supplementary because they form a 180 degree angle. As the name "linear pair" implies, the pair of angles form a straight line. Unlike the previous set of angles, these angles are not supplementary. So they aren't a linear pair. However, the angles do share a common ray. So they are adjacent.These angles combine to a right angle (aka 90 degrees). Therefore, they are complementary angles that form a sharp corner. These are vertical angles because they are opposite one another. Ignore ray OB and only focus on lines AD and EC. Vertical angles form whenever we have this X shape like this, and the vertical angles are opposite one another. Vertical angles are always congruent.3(4x+1)=15? X=

if a shirt selling for $ 18 is marked up to $20 then the percentage increased is equal to
Answers
Answer:
11.11%
Step-by-step explanation:
the increased price = 20-18 = $2
the percentage increased = 2/18 ×100%
= 11.11%
Answer: Percent increase = 11.11%
Concept:
Here, we need to know how to find the percentage of increase.
Percent increase is a measure of percent change, which is the extent to which something gains value.
Percent increase = [(final value - initial value) / initial value] × 100%
Solve:
Given information
Initial value = $18
Final value = $20
Given expression
Percent increase = [(final value - initial value) / initial value] × 100%
Substitute values into the expression
Percent increase = [(20 - 18) / 18] × 100%
Simplify values in the parentheses
Percent increase = [2 / 18] × 100%
SImplify by multiplication
Percent increase = 11.11 % (Rounded to the hundredth place)

Find the lateral area of the regular pyramid shown in the accompanying diagram. If necessary, express your answer in simplest radical form.
A. 90 units²
B. 540 units²
C. 1080 units²
D. 360+64√3 units²1
Answers
Answer:
B
Step-by-step explanation:
The lateral area of the regular pyramid shown in the diagram is 540 unit². Hence, option B is the right choice.
What is the area?The area of a figure is the two-dimensional space enclosed within the boundary of that figure.
How to solve the question?In the question, we are asked to find the lateral area of the regular pyramid shown.
A regular pyramid is one with all lateral faces the same.
In the given diagram, the pyramid shown has a hexagonal base. So it has 6 equal lateral faces.
Each lateral face is a triangle, with the base as 12 units and height as 15 units.
Thus, the area of one lateral face = (1/2)*12*15 units² = 90 units².
Thus, the total lateral surface area = Lateral surface area of one lateral face*number of lateral faces = 90 units²*6 = 540 units².
Thus, the lateral area of the regular pyramid shown in the diagram is 540 unit². Hence, option B is the right choice.

Jazmine is on a trịp to San Antonio, a distance of 330 km. She only has 3.5 hours to get to a job interview there. She gets stuck in traffic for the first 1.5 hours out of Houston and averages a speed of 60 km/hr. In order to not be late, what speed does she need to travel for the rest of the trip? (Organize your information carefully - total, first part, second part)
Answers
Answer:
Jazmine must travel for the rest of the trip at 120km/hr.
Step-by-step explanation:
To find the speed for the latter half of the trip necessary to arrive on time, we can divide the remaining distance by the remaining time.
The remaining distance, in km, is found by subtracting the distance already covered, which is the product of the speed during the first part of the trip and the elapsed time during this part, from the total distance:
[tex]330-1.5\times60=330-90=240[/tex]
The remaining time, in hr, is found by subtracting the elapsed time during the first part from the total time limit:
[tex]3.5-1.5=2[/tex]
Therefore, the necessary speed in km/hr is:
[tex]\frac{240}2=120[/tex]

How many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 15% antifreeze to get a mixture that is 60% antifreeze? Use the six-step method.
Answers
Answer:
405 gallons
Step-by-step explanation:
Let it be that the amount of gallons of a 70% antifreeze solution is x, when a mixture that is 60 percents of antifreeze is placed in y gallons
x+90=y - the equation of dependence between solutions
The amount of antifreeze in the first one is x/100*70= 0.7x (in gallons), in the second solution (15percents) antifreeze is 90/100*15=13.5 (in gallons).
In the mixture we should get there will be y/100*60=0.6y - gallons of antifreeze
0,7x+13.5=0.6y
We have two equations x+90=y and 0,7x+13.5= 0.6y
0.6x+54=0.6y
0.7x+13.5=0.6y
0.7x+13.5-0.6x-54= 0.6y-0.6y
0.1x-40.5=0
x=405- the answer
p.s. sorry, I don't know what the six-step method is. But the answer is right.
