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 ☑️

Good luck on your assignment and enjoy your day!

Answer:

The 6th term will be:

[tex]a_6=\frac{729}{16}[/tex]

Step-by-step explanation:

Given

To determine

a₆ = ?

A geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

substituting a₁ = 6, r = 3/2

[tex]a_n=6\cdot \left(\frac{3}{2}\right)^{n-1}[/tex]

Determining 6th term

substituting n = 6 in the given equation

[tex]a_n=6\cdot \left(\frac{3}{2}\right)^{n-1}[/tex]

[tex]a_6=6\cdot \left(\frac{3}{2}\right)^{6-1}[/tex]

    [tex]=6\cdot \frac{3^5}{2^5}[/tex]

    [tex]=\frac{3^5\cdot \:6}{2^5}[/tex]

    [tex]=\frac{3^5\cdot \:2\cdot \:3}{2^5}[/tex]

Cancel the common term

     [tex]=\frac{3^6}{2^4}[/tex]

     [tex]=\frac{729}{16}[/tex]

Therefore, the 6th term will be:

[tex]a_6=\frac{729}{16}[/tex]

Answer:

9, plug 3 in for x and multiply 3(3)

2/3 is the slope of the graph of the equation 4x - 6y=2. Option C is correct.

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

4x+4y..........................

Answer:

y=-3.571

Step-by-step explanation:

To get rid of the x's make the other x cancel out the other.

5x-y=25+(-5(x+4y=-10)=-21y=75= -3.571

Answer:

x+4y =10

5x-y =25

Step-by-step explanation:

x=10-4y

5(10-4y)-y =25

50-20y-y =25

50-21y = 25

-21y = 25-50

-21y =-25

y =25/21

Substitute y =25/21 in equation 1

x + 4(25/21) = 10

x +100/84 =10

x=10-100/84

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

Step-by-step explanation:

Given that,

A gray crayon is made with 5 mL of black wax for every 6 mL of white wax.

We need to find the mixture will create the same shade of gray.

For this we need to make the ratio same.

If we multiply 5 mL and 6 mL by 3 to make the ratio same.

5 mL × 3 = 15 mL

6 mL × 3 = 18 mL

Hence, 15 mL of black wax mixed with 18 mL of white wax  is mixed so as to make the ratio same.

Answer:

15ml of black wax mixed with 18ml of white wax

35ml of black wax mixed with 42ml of white wax

Answer:

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: Slope =riserun Slope = rise run .

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.

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
