A gray crayon is made with 5\text{ mL}5 mL5, start text, space, m, L, end text of black wax for every 6\text{ mL}6 mL6, start text, space, m, L, end text of white wax.

Answers

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

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.

what is the value of y in the solution to the system of equations 5x-y=25 and x+4y=-10

Answers

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

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

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 ☑️

What connections can we make between finding the slope of a line connecting two points and the distance between those same two points?

Answers

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 .

C.2/3
D.3/2​

Answers

It is C 2/3 because 4x=2 and 6y=3

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:
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

Find the 6th term of the geometric sequence whose common ratio is 3/2 and whose first term is 6.

Answers

Answer:

The 6th term will be:

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

Step-by-step explanation:

Given

a₁ = 6common ratio r = 3/2

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]

∛2 is the radical part of both ∛54 and ∛128  when the expression are simplified.

What is Number system?

A number system is defined as a system of writing to express numbers.

Let us write the prime factors of 54.

54/2 = 27

When fifty four is divided by 2 we get twenty seven.

27/3=9

Twenty seven divided by three is nine.

9/3=3

So 54 = 2 × 3 × 3 × 3

we know ∛ 3 × 3 × 3 = 3

∛54 = ∛ 3 × 3 × 3×2 = 3∛2

Hence, ∛2 is the radical part of both ∛54 and ∛128  when the expression are simplified.
