Multiply 4 by 10%.
10% ⇒ 0.1
4 × 0.1 = 0.4
Subtract 0.4 from 4.
4 - 0.4 = 3.6 (price with discount)
Multiply 3.6 by 6%.
6% ⇒ 0.06
3.6 × 0.06 = 0.216
Add 0.216 to 3.6.
0.216 + 3.6 = 3.816
Round 3.816 to the hundredths.
3.816 ⇒ 3.82 (price with tax)
The new price of toothbrushes is $3.82.
If Juan intends to put fencing around the enclosure, that means that we are looking at the perimeter of the image (the outside). We can count the amount of lines between the dots to determine how much fencing he will need. After counting the perimeter of this figure, we see that the total is 22. We do not know what the units are, so for now we can just say that he will need 22 units of fencing to fully enclose this shape.

Answer:
The answer is true.
Step-by-step explanation:
Sample methods that embody random sampling are often termed probability sampling methods.
Yes this is a true statement.
Random sampling means picking up the samples randomly from a whole population with each sample having an equal chance of getting selected.
For example- selecting randomly 10 students from each class of a school, to survey for the food quality in school's cafeteria.
And this is a type of probability sampling methods. Other types are stratified sampling, cluster sampling etc.
Answer:
k = -4
Step-by-step explanation:
Given system of equations are,
-3x-3y = h
-4x + ky = 10
We have to find the values of h and k such that system of equations has no solution.
The standard form of system of equation in two variables can be given by,
And condition for the system of equations has no solution is given by,
So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,
=> k = -4
and 
So, the value of h and k for above given system of equations is
and k = -4.
