Which statement is true?
A) The value of money that you save increases over time.
B) The value of money remains constant over time.
C) The present value of money is greater than its future value.
Answer:
I would say A
Answer:
Step-by-step explanation:
It is anything but A. There is too much money floating around to maintain its value or buying power. The Federal Reserve just keeps on printing more. The net effect is that your money is worth less because there is more of it.
B: Our problem is that money does not remain constant. The answer cannot be B
C: is the answer. That is exactly what is happening today.

Triangle J K L is shown. Angle K J L is 58 degrees and angle J L K is 38 degrees. The length of J K is 2.3 and the length of J L is k.
Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartFraction sine (uppercase C) Over c EndFraction
Which measures are accurate regarding triangle JKL? Select two options.
m∠K = 94°
k ≈ 3.7 units
k ≈ 4.6 units
KL ≈ 2.5 units
KL ≈ 3.2 units
Answer:
C and D 3.7 and 2.5
Step-by-step explanation:
The value of k using the law of sines is 2.05.
What is a law of sine?Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.
In Triangle JKL
< K J L = 58 degrees
< J L K = 38 degrees.
and, J K = 2.3, J L = k.
As, <KJL + <JKL + <LKJ = 180
58+ 23 + <LKJ = 180
<LKJ = 99 degree.
Using Law of sines
k/ sin K = j/ sin J
k/ sin 99 = 2.3/ sin 58
k- 2.05

Jackie sold 3 times as many meals as Yolanda. Thomas sold 2 more meals than Yolanda. If they sold a total of 122 meals, how many meals did Yolanda sell?
Answer:
the number of meals that yolanda sold is 24
Step-by-step explanation:
The computation of the number of meals that yolanda sold is shown below:
Given that
The total meals sold is 122
Let yolanda meals be x
So jackie meals would be 3x
And, thomas meals be x + 2
So according to this
the equation is
x + 3x + x + 2 = 122
5x + 2 = 122
5x = 120
x = 24
Hence, the number of meals that yolanda sold is 24

Write an equation in slope-intercept form that passes through (5, -8) and runs perpendicular to y = 5/2x + 4
y= (-2/5)x-6
Step-by-step explanation:
the slope of the line perpendicular the the given line is found by the formula m1.m2= -1 hence m2= -2/5
using the slope-intercept form
y+8= -2/5(x-5) y= (-2/5)x-6
The capacity of Dr Khan's oil tank is 1,200 litres.
There are currently 650 litres of oil in the tank.
Oil costs 77.2p per litre.
Dr Khan gets a 5% discount on the price of oil.
How much does it cost Dr Khan to fill the oil tank?
Answer:
it costs = 40337p
Step-by-step explanation:
a) 1200 - 650 = 550L
b) 77.2p - 77.2 x0.05 = 73.34p per litre
c) the total money it costs to be filled the the oil tank by Dr Khan is 73.34 x 550L = 40337

What is the simple interest on $40,000 for 10 years at 12%?
A.)$50,000
B.)$48,000
C.)$64,000
D.)$55,000
Answer:
To find the simple interest, we multiply 40000 × 0.12 × 10 to get that:
The interest is: $48000.00
Usually now, the interest is added onto the principal to figure some new amount after 10 year(s),
or 40000.00 + 48000.00 = 88000.00. For example:
If you borrowed the $40000.00, you would now owe $88000.00
If you loaned someone $40000.00, you would now be due $88000.00

what is this(9 + 4) × (8 -7)
Answer:
13
Step-by-step explanation:
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
I hope this helps you :D
Answer:

Step-by-step explanation:

lol please helppppppp
Answer:
Equation for Leandro: y=0.3x+8.95
Equation for Tina: y=0.25x+8.95
The slope is not the same, because in this equation, the coefficient of the x (the number right before the "x") isn't the same. 0.3 does not equal 0.25.
However, the y-intercept is the same, as for both equations it is 8.95.
From this, we can see that there is only one solution, at the y-intercept of (0,8.95).

If the simple interest on $6,000 for 9 years is $4,320, then what is the interest rate?
The rate is ?
Answer:
6.48%
Step-by-step explanation:
the rule of the simple interest is:
I=PRT
but here we want the rate, and we have I and P and T
so put the rate on 1 side, and all the given numbers in other side
the rule will be like this:
R=I/PT
R=4320/6000×9
R=6.48%

If y - 18 = 14, then what is the value of 3(y + 5) ?
Answer: y = 980.333
Step-by-step explanation:
y-18=14
add 18 to each side
y = 32
Substitute 32 for y in 3(y+5)
3(32 + 5)
3(37)
111
So 3(y+5) = 111
Find the value of the variable y:
y-18=14 Add 18 on both sides:
y = 32
= 3y+15
_____________________
3y+15 = 2,956
3y+15 = 2956
3y = 2941
y = 980.333
(x+6) (x-2) multiply out
Answer:
x² + 4x - 12
Step-by-step explanation:
(x + 6)(x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 6(x - 2) ← distribute parenthesis
= x² - 2x + 6x - 12 ← collect like terms
= x² + 4x - 12

The length of a rectangle is 3 cm more than twice the width. The area of the rectangle is 65 square centimeters. Find the dimensions of the rectangle.
Answer:
5 cm and 13 cm
Step-by-step explanation:
Let b be the width of the rectangle.
Length = 3+2b
The area of the rectangle is 65 cm²
We need to find the dimensions of the rectangle. The area of a rectangle is given by :
A = lb
[tex]65=(3+2b)b\\\\65=3b+2b^2\\\\3b+2b^2-65=0\\\\b=5\ cm,-6.5\ cm[/tex]
Neglecting the negative value, the width of the rectangle is 5 cm.
Length = 3+2b
=3+2(5)
=3+10
=13 cm
Hence, the dimensions of the rectangle are 5 cm and 13 cm.
Write an equation of the circle with center (-2,5) radius 9
Answer:
(x+2)²+(y-5)² = 81
Step-by-step explanation:
The formula for calculating equation of a line is expressed as
(x-a)²+(y-b)² = r²
(a,b) are the points
r is the radius
Given
Point = (-2,5)
Radius = 9
Substitute
(x-(-2)²+(y-5)² = 9²
(x+2)²+(y-5)² = 81
Hence the required equation is (x+2)²+(y-5)² = 81
