Its an example  Unit rate becuase theres the #1 in it and its constant

Step-by-step explanation:

A rate is more like a ratio of 2 different number

3:6

or

9:18

When these are simplified you’ll get 1 in one of the 2 numbers but then it would be a unit rate

Rate= no #1

Unit rate= Defined as a number 1

Answer:

$9.60 for 12 sandwiches

To solve the problem we will calculate the cost of 1 sandwich first.

The cost of 12 sandwiches is 9.6 Rands.

Given

15 sandwiches are sold for 12 Rand

We know the cost of 15 sandwiches is 12 Rand, therefore,

[tex]\text{Cost of 1 Sandwich} = \dfrac{\rm 12\ Rand}{\rm 15\ Sandwich}[/tex]

[tex]\text{Cost of 1 Sandwich} = \dfrac{12}{15} = 0.8\ \rm Rand/Sandwich[/tex]

The cost of 12sandwiches can be calculated using the cost of 1 sandwich,

[tex]\text{Cost of 12 Sandwiches} = \text{Cost of 1 sandwich} \times 12[/tex]

                              [tex]= 0.8 \times 12 = 9.6\ \rm Rand[/tex]

Hence, the cost of 12 sandwiches is 9.6 Rands.

Answer:

546/42= 13

559/13= 43

43 attendees

Answer:

a) 13%

b) 45%

c) 16%

Step-by-step explanation:

To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31,  therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.

Answer:

2 3/20 metres

Step-by-step explanation:

Area of the rug = Length × width

Given

Area = 7 1/6 metres = 43/6 m

Length = 3 1/3 metres = 10/3 m

Required

Width

From the formula

A = LW

W = A/L

Substitute the given values

W = 43/6÷10/3

W = 43/6×3/10

W = 43/2 ×1/10

W = 43/20

W = 2 3/20 m

Hence the width of the rug is 2 3/20 metres

Answer: 1.20133333333 repeatedly

Answer:

4x + 1 is the simplified expression

Step-by-step explanation:

We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.

The first step involves mulitplication and distribution property:

1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)

2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).

Bow the expression is almost simplified as it is:

2x + 1 -(-2x)

The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:

3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.

4) Now we know that -(-2x) is the same as: + 2x.

5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.

Hope you understood this and have a nice day!

Answer:

1/2

Step-by-step explanation:

Let the total pie be 2

She ate 1/6

Her brother ate 1/3

If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:

1-(1/6+1/3)

= 1-((1+2)/6)

= 1-3/6

= 1 - 1/2

=1/2

Hence the fraction she gave her friend is 1/2

The value of the angle,x=50.531°. The angle is obtained by the sin law.

A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

From the sin rule;

[tex]\rm \frac{AB}{sin \angle ACB} =\frac{BC}{sin \angle BAC} \\\\ \rm \frac{5.6}{sin \angle ACB} =\frac{9.3}{sin \angle 50^0} \\\\ \angle ACB=27.49^0[/tex]

For the same angles;

[tex]\rm \angle ACB=\angle BCD[/tex]

From the exterior angle theorm ;

[tex]\rm \angle BCD+\angle CBD= \angle ADB[/tex]

∠CBD=x

∠ABD=78°

Putting the obtained values;

27.469°+x=78°

x=78°-27.469°

x=50.531°

Hence,the value of the angle,x=50.531°.

Answer:

X: x=3-3/5y

Y: y=5-5/3x

Step-by-step explanation:

For X:

-3y on both sides will result in:

5x=15-3y

5x/5=15/5-3y/5 (divide 5 on both sides)

x=3-3/5y

For Y:

-5x on both sides will result in:

3y=15/3-5x/3 (divide 3 on both sides)

y=5-5/3x

Answer:

Step-by-step explanation:

a). [tex]\frac{5\pm\sqrt{-4}}{3}[/tex] = [tex]\frac{5}{3}\pm \frac{\sqrt{-4}}{3}[/tex]

               = [tex]\frac{5}{3}\pm\frac{2\sqrt{(-1)} }{3}[/tex]

               = [tex]\frac{5}{3}\pm\frac{2i}{3}[/tex] [Since, i = [tex]\sqrt{(-1)}[/tex]]

b). [tex]\frac{10\pm\sqrt{-16}}{2}[/tex] = [tex]\frac{10}{2}\pm \frac{\sqrt{-16}}{2}[/tex]

Answer:

slope: -4, y intercept: (0, -5)

Step-by-step explanation:

Answer:

It is: (f(2) - f(0))/(2 - 0)

f(2) = 250(0.5)(2) = 250

f(0) = 250 (0.5)(0) = 0

So: (250 - 0)/(2 - 0) = 250/2 = 175

The average rate of change is 175.
