Answer:
30 milk chocolates
Step-by-step explanation:
We can set up the equation like this: 3*x=18
So we can solve that by 18/3 = 6
Now the mile chocolates are 5x, so if you multiply 5 by 6, you get 30

Find the area of △LKJ.
Answer:
[tex]A=600\: u^{2}[/tex]
The correct answer is letter c.
Step-by-step explanation:
The area equation of a triangle is given by:
[tex]A=\frac{bh}{2}[/tex] (1)
Where:
b is the base
h is the height
Let's find first the angle MJK (α), using the tangent definition.
[tex]tan(\alpha)=\frac{24}{32}[/tex]
[tex]\alpha=tan^{-1}(\frac{24}{32})[/tex]
[tex]\alpha=36.9^{\circ}[/tex]
Now, if α = 37° then β (angle JLK) must be:
[tex]37^{\circ} + \beta + 90^{\circ}=180^{\circ}[/tex]
[tex]\beta=53^{\circ}[/tex]
Now, we can find the distance ML using again the tangent definition:
[tex]tan(\beta)=\frac{24}{ML}[/tex]
[tex]ML=\frac{24}{tan(53)}[/tex]
[tex]ML=18[/tex]
The base of the triangle LKJ will be:
[tex]b=32+ML=32+18=50[/tex]
Therefore, using equation (1) the area of △LKJ will be:
[tex]A=\frac{50*24}{2}[/tex]
[tex]A=600\: u^{2}[/tex]
The correct answer is c.
I hope it helps you!
If you graphed this system, what would the solution be?
y=2x
y=−1x−6
Answer:
(-2, -4)
Step-by-step explanation:
[y = 2x, y = -x -6]
Solve by substitution:
-x - 6 = 2x
simplify
3x = -6
divide
x = -2
Plug back in one equation to solve for y coordinate:
y = 2(-2)
y = -4
(-2, -4)

question
(60-5.8) ÷ 5 - 3^2
can you please explain it in an essay type like words and not just show me the answer I need it to show me how you got the answer don't give me just the answer
Answer:
1.84
Step-by-step explanation:
First you solve what is in the parenthesis.
60 - 5.8 = 54.2
The equation is now 54.2 ÷ 5 - 3^2
Now, you do the exponents. 3^2 = 9 since 3 to the second power is just another way to write 3 x 3.
Your equation is now 54.2 ÷ 5 - 9
You then divide 54.2 ÷ 5
54.2 ÷ 5 = 10.84
The last equation is 10.84 - 9
10.84 - 9 = 1.84

Jenna's only source of income is from her job at a car wash, where she works 25 hours each week. She is paid $9.90 per hour. What is her net weekly income if she pays $30.70 in payroll tax each week?
Answer: 216.8$
Step-by-step explanation:
25 x 9.9 = 247.5
247.5 - 30.70 = 216.8
The students of a high school are 51% males. Of the students at this high school 45% of males and 40% of females said they regularly attend concerts.
Answer:
(b) Probability that a student is male and attends concert = 22.95%
(c) Probability that a student is female and does not attend concert = 29.4%
(d) Probability that a student attends concerts = 42.55%
Step-by-step explanation:
P.S - The exact question is -
Given - The population of a high school is 51% male. 45% of the males and 40% of the females attend concerts.
To find - (a) Make a tree diagram based on the information above.
(b) Find the probability that a student is male and attends
concerts.
(c) Find the probability that a student is female and does not
attend concerts.
(d) Find the probability that a student attends concerts.
Proof -
Let the total population of the high school = 100 x
Given that,
The students of a high school are 51% males
⇒Total males in the high school = 51% × 100 x
= [tex]\frac{51}{100}[/tex] × 100 x = 51 x
⇒Total males in the high school = 51 x
⇒Total females in the high school = 100 x - 51 x = 49 x
Now,
Given that,
Of the students at this high school 45% of males and 40% of females said they regularly attend concerts.
⇒Total number of males that attend the concert = 45% × 51 x
= [tex]\frac{45}{100}[/tex] × 51 x = 22.95 x
⇒Total number of males that attend the concert = 22.95 x
And
Total number of males that do not attend the concert = 51 x - 22.95 x
= 28.05 x
⇒Total number of males that do not attend the concert = 28.05 x
Also,
Total number of females that attend the concert = 40% × 49 x
= [tex]\frac{40}{100}[/tex] × 49 x = 19.6 x
⇒Total number of females that attend the concert = 19.6 x
And
Total number of females that do not attend the concert = 49 x - 19.6 x
= 29.4 x
⇒Total number of females that do not attend the concert = 29.4 x
(a)
The tree diagram is as follows :
(b)
Probability that a student is male and attends concert = [tex]\frac{22.95 x}{100 x}[/tex] × 100 %
= 22.95%
⇒Probability that a student is male and attends concert = 22.95%
(c)
Probability that a student is female and does not attend concert = [tex]\frac{29.4x}{100x}[/tex] × 100%
= 29.4%
⇒Probability that a student is female and does not attend concert = 29.4%
(d)
Probability that a student attends concerts = [tex]\frac{22.95x + 19.6x}{100x}[/tex] ×100%
= [tex]\frac{42.55}{100}[/tex] ×100%
= 42.55%
⇒Probability that a student attends concerts = 42.55%

Which of the following is the reciprocal of 1/5 ?
answers
5
1/5 5/5 1
Answer:
5
Step-by-step explanation:
A reciprocal is the inverse of a fraction.
To find it just flip the numerator and denominator.
1/5 becomes 5/1, or 5.
The calculated reciprocal of the number 1/5 is 5
How to determine the reciprocal of the numberFrom the question, we have the following parameters that can be used in our computation:
Number = 1/5
By definition, the reciprocal of a number x is represebted as
reciprocal = 1/x
In this case,
x = 1/5
Substitute the known values in the above equation, so, we have the following representation
reciprocal = 1/(1/5)
Evaluate
reciprocal = 5
Hence, the reciprocal is 5

24 = 2/3 of the total cookies
24/x = 2/3
cross multiply
24(3) = 2x
72 = 2x

The area of a rectangle is 192 in ^2. The ratio of the length to the width is 4:3. Find the length and the width.
The length of the rectangle is ___ in.
The width of the rectangle is___.
Answer:
Length = 16 in
Width = 12 in
Step-by-step explanation:
Given:
Area of a rectangle = 192 in²
Ratio(length to width) = 4:3
Find:
Length and the width
Computation:
Ratio(length to width) = 4:3
So,
Length = 4a
Width = 3a
Area of a rectangle = Length x Width
192 = 4a x 3a
192 = 12a²
a² = 16
a = 4
Length = 4a = 4 x 4 = 16 in
Width = 3a = 3 x 4 = 12 in

Answer:
The answer is g(x)=(x-2)^2+1
Step-by-step explanation:
The equation of the blue graph is y = (x - 4)² + 1.
Option D is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The graphs of y = x² and y = (x - 4)² + 1 are both parabolas.
The graph of y = x² is a simple upward-facing parabola that passes through the origin.
As x increases or decreases, the value of y increases but at an increasingly slower rate until it reaches a minimum at x = 0, where it turns back upwards and continues to increase at an increasingly faster rate.
The graph of y = (x - 4)² + 1 is also a parabola, but it is shifted 4 units to the right and 1 unit up compared to y = x².
Thus,
The equation of the blue graph is y = (x - 4)² + 1.
