To find the answer, we need to look at the information. We have:
12 pencils bought
0.57 per pencil
Paid with a 10$ bill.
First, find out how much he spent on pencils.
Multiply 12 by 0.57.
This will give you 6.84.
Next, we know he paid with a 10 dollar bill.
Subtract the amount due from the amount paid.
10 - 6.84.
This will give you 3.16.
So, the amount of change due is 3.16

12(0.57)= 6.84

10-6.84= 3.16

Mr. Turner’s change is $3.16.

Hope this helps!

Montell is 30 years younger than his mother. in 5 years, montell age will be 1-3 of his mother’s age. find montell mother’s age

Liono4ka [1.6K]

So this can be solve by establish two equation:
let x be age of montell
y be tha age of her mom
for the first equation (Montell is 30 years):
x = y - 30
second equation ( in 5 years )

x + 5 = ( y + 5 ) ( 1/3)
solving the equation simultaneously

x = 10 years old
y = 40 years old

Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

$\frac{YX}{YZ}$ = $\frac{XR}{ZR}$ , substitute values

$\frac{11.9}{YZ}$ = $\frac{7}{5}$ ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5

2) A circle has a radius of 8 cm. What is its circumference? 8 cm

egoroff_w [7]

Answer

16π cm ≈ 50.2655 cm

Step-by-step explanation

To find the circumference of a circle, we can use the equation C = 2πr.

C stands for the circumference while r stands for the radius. We can see that there is a proportional positive linear relationship between radius and circumference for all circles, and that to find circumference when we have a radius value, we multiply the radius value by 2π.

The value of π, also called pi, is a constant and is the ratio of a circle's circumference to its diameter (the diameter is twice the radius, hence the 2 in the equation). Note that π is a constant and applies to all circles because all circles are similar.

Since we know the value of r, or the radius, given as 8 cm in the question, we can plug this value into the equation C = 2πr from earlier.

C = 2πr (plug in 8 cm for the radius)

C = 2π * 8

C = 16π cm

Since the radius is in units of cm (centimeters), the circumference is also in units of cm (centimeters).

16π cm is the exact value of the circumference. However, if we want this circumference in decimal form, we would multiply 16 by the decimal form of π which is approximately 3.1416. Note that π actually has an infinite amount of decimals and that this 3.1416 is actually a rounded π value

C = 16π

C ≈ 16 * 3.1416

C ≈ 50.2655 cm rounded to four decimal places
