If $5,000 is invested at 6% interest, how much money must be invested at 8% interest so that the total interest from the two investments is $660 after one year?
Answers
Answer:
$4500
Step-by-step explanation:
Simple Interest formula = Principal × Rate × Time
Let the amount of the money invested at 8% Interest = x
Hence:
$5000 × 6% × 1 + x × 8% × 1 = $660
$300 + 0.08x = $660
0.08x = $660 - $300
0.08x = $360
x = $360/0.08
x = $4500
Therefore , the amount that must be invested at 8% interest is $4500

what is the slope of the graph of the equation 4x - 6y=2?
A.-4
B.-1
C.2/3
D.3/2
Answers
2/3 is the slope of the graph of the equation 4x - 6y=2. Option C is correct.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The equation of the graph is 4x - 6y=2
We need to convert this to the slope intercept form y=mx+b
4x - 6y=2
Subtract 4x from both sides
-6y=2-4x
Divide both sides by -6
y=-2/6+4/6x
y=2/3x-2/6
Hence 2/3 is the slope of the graph of the equation 4x - 6y=2

Answer:
A,C,E
Step-by-step explanation:
Answer:
B. n ≥ -24.
D. The circle is closed.
E. The arrow points right.
Step-by-step explanation:
Step 1: Multiply both sides by -3/2, the reciprocal of -2/3. Since -2/3 is negative, the inequality direction changes.
(-2/3 * -3/2)n ≤ 16(-3/2)
n ≥ 16(-3/2)
Step 2: Express 16(-3/2) as a single fraction.
n ≥ 16(-3)/2
Step 3: Multiply 16 by -3 to get -48.
n ≥ -48/2
Final Step: Divide -48 by 2 to get -24.
n ≥ -24 is the final answer.
With inequalities that have this (≥), the circle should be closed (D) and the arrow goes right (E).

at southeast middle school 16 1/4 % of the students wear braces. what fraction of the students wear braces?
Answers
Answer:
4
Step-by-step explanation:
divide them
Hey there!
16 1 / 4% = 16(4) + 1 = 64 + 1 = 65
65 / 4% = 16.25%
• Percentages usually run out of 100
16.25 / 100
• Finding out the ratio of your given number, multiply the numerator and denominator by the number 4
16.25 * 4 / 100 * 4
16.25 * 4 = 65 (numerator)
100 * 4 = 400 (denominator)
• Equation: 65 / 400
• REDUCE the GIVEN FRACTION (65/400)
• Once when you have the fraction reduced you should have came up with: 13/80 (aka your answer)
• Answer: 13/80 ☑️

sin41 × 13.5 = 8.85679
rounded to 3 sig fig
= 8.57
Answers
Answer:
8.86 cm
Step-by-step explanation:
The sine rule shows the relationship between the sides of a triangle and its opposite sides. Sine rule states that given a triangle with side a and opposite angle A, side b and opposite angle B, side c and opposite angle C then:
[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
From the image attached, let AB = x, its opposite angle is 41°. BC = 13.5 cm and its opposite angle is 90° (right angle). Therefore using sine rule:
[tex]\frac{x}{sin(41)} =\frac{13.5}{sin(90)} \\\\x=sin(41)*\frac{13.5}{sin(90)}\\\\x=8.8568\\\\ x=8.86\ cm\ to\ 3\ s.f[/tex]
x = AB = 8.86 cm

A. 1 1/4
B. 9 3/8
C. 10
D. 12 1/2
Answers
Answer:
Option D: [tex]12\frac{1}{2}[/tex] is the correct answer.
Step-by-step explanation:
Given that:
3/4 inches on map are equal to [tex]7\frac{1}{2}[/tex] miles
We will find the unit rate in term of inches.
[tex]\frac{3}{4}\ inches = 7\frac{1}{2}\\\\Unit\ rate = \frac{15}{2}*\frac{4}{3}\ miles\\\\Unit\ rate = 10\ miles\ per\ inch[/tex]
Total distance covered by Bonnie according to map;
Total distance = [tex]\frac{1}{2}+\frac{3}{4} = \frac{2+3}{4}[/tex]
Total distance = [tex]\frac{5}{4}\ miles[/tex]
Actual distance = [tex]\frac{5}{4}*10 = \frac{25}{2}\ miles \\[/tex]
Actual distance = [tex]12\frac{1}{2}\ miles[/tex]
Hence,
Option D: [tex]12\frac{1}{2}[/tex] is the correct answer.

Answers
Answer:
Rewrite in slope-intercept form.
Tap for more steps...
y=−4/5x+6
Using the slope-intercept form, the slope is −4/5 .
m=−4/5
All lines that are parallel to y=−4/5x+6
have the same slope of −4/5.
mparallel=−4/5
Step-by-step explanation:
The line parallel to the x- axis which is given equation is [tex]y=-\frac{4}{5}+6[/tex]
Parallel lines:Parallel lines are lines that have the same slope. They are lines that do not meet at any given point and the distance between the two points is constant. For example, if we have a line [tex]y=m_1x+c_1[/tex] which is parallel to the line [tex]y=m_2x+c_2[/tex] then: [tex]m_1=m_2[/tex] and we can rewrite the equation of the second line as :[tex]y=m_1x+c_2.[/tex]
We have the equation is:
[tex]y=-\frac{4}{5}+6[/tex]
Now, The equation is in the form of y = mx + c
Hence, The value of slope - intercept form is : m = -4/5
We have to plot the line in the graph :
[tex]y=-\frac{4}{5}+6[/tex]
