She spent 1/3
of her money on a helmet:
13/20
of her money on a skateboard
The rest was spent on stickers
She spent
.
How much did Ana spend on stickers?
Answer: 3
Step-by-step explanation:
180 / 1/3 = 60
180 / 13/20 = 117
117 + 60 = 177
180 - 177 = 3
An absolute value function can be written as a piecewise function always, sometimes, or never? Your answer should demonstrate an understanding of both types of functions. Explain your answer using complete sentences.
Hello,
Let us choose an element x of the Real Numbers. So x can either be positive or negative. So we have two case to study :
Case 1 : x is positive.
If x is positive, that is, x = 0, 1, 2, 3, ....
then the absolute value gives us the same number : |0| = 0
|1| = 1
|2|= 2
etc.
so the absolute value of x positive equals x : |x| = x
Case 2 : x is negative.
If x is negative, that is, x = - 1, - 2, -3, .....
then the absolue value gives us the opposite value : |-1| = - (-1) = 1
|-2| = -(-2) = 2
|-3| = -(-3) = 3
(Remember the product of two negative sign is a positive signe : -1 * -1 = +1)
And so we can join both cases as a piecewise function, writing :
|x| = [tex]\left \{ {{x=x if x\geq 0 } \atop {x= - x if x<0 }} \right.[/tex]
so x = x if x ≥ 0 and x = - x if x < 0
Finally the answer is : it depend on the function itself. If the function takes both positive and negative value, then the absolute value of the function will be written as a piecewise function. If the function takes only positive or negative value, then it won't be written as a piecewise function.

If there are 45 students in a classroom, of which 52% are women under 18 years of age. Please indicate:
a. How many male students are there in the class?
b. Is it possible to say that most of the students are minors?
Answer:
A. 22
b. Yes. Because there are 23 woman and they are all under 18 and there are 22 males. In which we don't know if they are underage, but it doesn't really matter because there is one more girl in the room than boys. And all woman are underage so there for there are more underage students in the room.
Step-by-step explanation:
Hope this helps :)
Pls make brainliest :p
And have an amazing day <3
Answer:
there would be 21.6 males. That doesn't work, so you'd have 21 or 22(probably 22)
yes, most of the students are minors. 52% percent at least are under 18 years. 52% is more than half, so that would make it so most are minors.
Step-by-step explanation:
There are two integers that combine to -19 and their product is 70. Find the two integers, then the SMALLER integer is your answer for this question?
Answer:
-14
Step-by-step explanation:
a + b = -19
(a)(b) = 70
To solve this problem, isolate one variable in one of the two equations and then substitute it in.
So, a + b = -19
-> a = -19 - b
b(-19 - b) = 70
Distribute.
-19b - b^2 = 70
Move all to one side.
b^2 + 19b + 70 = 0
Factor. Find two numbers that multiply to 70, but add to 19.
(b + 5) (b + 14) = 0
Zero product rule.
b = -5, b = -14
Now, substitute the two answers for b back into the original equation for a.
a - 14 = -19
a = -5
a - 5 = -19
a = -14
So, the answers are b = -5, b = -14, a = -5, a = -14. Since you said that the smallest integer is the answer, the answer is -14.
Use properties of exponents to solve for a and b in the problem below. No calculator allowed. Please help; I don't know what I'm doing.

Triangle ABC is congruent to triangle DEF. Angle B is a right angle, and m∠C = 42°. What is m∠D?
Answer:
Step-by-step explanation: Triangle ABC is congruent to triangle DEF. Angle B is a right angle, and m∠C = 57°. What is m∠D? can someone help plsss
If Triangle ABC is congruent to triangle DEF then measure of angle D is 48 degrees.
Given, Triangle ABC is congruent to triangle DEF.
Angle sum property of triangle: Sum of all the interior angles of the triangle is 180 degrees.
Congruent triangles: When two triangles are congruent they are similar in shape and coincide when superimposed.
Now in triangle ABC,
∠B = 90°
∠C = 42°
Apply angle sum property,
∠A + ∠B + ∠C = 180 degrees
∠A + 90° + 42° = 180°
∠A = 48°
When Triangle ABC is congruent to triangle DEF,
∠A = ∠D
∠B = ∠E
∠C = ∠F
Thus measure of angle D is equal to measure of angle A.
∴∠A = ∠D = 48°
