(Level 4) In a bag of orange, red, and yellow, 60% are orange, and 10% are red. There
are 6 yellow marbles in the bag. If you increase the number of orange marbles by 50%,
how many orange marbles are in the bag?
The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%
90% = 18
And we have to add 4 more because 10%×2.
So the total comes to 18+4= 22.

Find the perimeter of this semi-circle with diameter, d = 65cm. Give your answer rounded to 1 DP.
Answer:
1658.3
Step-by-step explanation:
the perimeter of a semi - circle is simply half the circumference of a circle.
that is ;
1 / 2 ( pi ( r² ) )
where;
pi = 3.14 ( this is a constant that should be known and also equals 22 / 7 )
r = radius ( or half a diameter )
in our question, we are given a diameter with no radius
this means that we will have to halve the diameter to give us our radius
that is;
d = 65cm
r = 65 / 2
r = 32.5
so, using our formula;
1 / 2 ( 3.14 ( 32.5² ) )
1 / 2 ( 3.14 ( 1056.26 ) )
1 / 2 ( 3316.65 )

A factory has 203 workers. There are 70 more males than females. Let x represent the number of males and let y represent the number of females. Which system of equations represents this situation?
Equation:
X+Y=203
X=70
Answer:
x - y = 70 and x + y = 203 are the required system of equations represents this situation.
Step-by-step explanation:
Given that factory has 203 workers
Let "x" represent the number of males and let "y" represent the number of females
There are 70 more males than females. Which means,
Number of males = 70 + number of females
x = 70 + y
On rearranging we get,
x - y = 70 ----> equation 1
It is given that factory has 203 workers, which means number of males and females is equal to 203
Number of males + number of females = total workers
x + y = 70 ---- equation 2
So equation 1 and equation 2 represents the system of equations for this situation
x - y = 70 and x + y = 203 are the required system of equations

Solve for x
And show work
Answer:
x = -8
Step-by-step explanation:
1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.
2. Given the above information, that means x + 96 + 100 + x = 180.
3. (Solving for equation above)
Step 1: Simplify both sides of the equation.
[tex](x+x) + (96+100)=180[/tex] [tex]2x + 196 = 180[/tex]Step 2: Subtract 196 from both sides.
[tex]2x + 196 - 196 = 180 - 196[/tex] [tex]2x = -16[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{-16}{2}[/tex] [tex]x = -8[/tex]Step 4: Check if solution is correct.
[tex]-8 + 96 + 100 - 8 = 180[/tex] [tex]88 + 100 - 8 = 180[/tex] [tex]188-8=180[/tex] [tex]180=180[/tex]Therefore, x = -8.
Answer:
x = - 8
Step-by-step explanation:
x + 96 and 100 + x are adjacent angles on a straight line and sum to 180°, so
x + 96 + 100 + x = 180 , that is
2x + 196 = 180 ( subtract 196 from both sides )
2x = - 16 ( divide both sides by 2 )
x = - 8

Answer:
100cm
Step-by-step explanation:
The relationship between the ratio and the heights is 20. i.e 4 : 5 = 80 : 100
Hope this helps, please tag brainliest.
The height of the taller boy is 100cm.
What is ratio?Ratio, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Let the height of the taller boy be x cm and smaller boy be y cm.
According to the given question.
The ratio of height of the two boys is 4:5.
Since, it is obvious that 4:5 is the ratio of the height of smaller boy to the taller boy. Because k will be the ratio of proportionality then 4k will given the smaller value and 5k will give the larger value therefore, 4:5 represents the ratio of height of smaller boy to the taller boy.
[tex]\implies \frac{y}{x} =\frac{4}{5}[/tex]
Also, the height of the shorter boy is 80cm.
Therefore,
[tex]\frac{80}{x} = \frac{4}{5}[/tex]
[tex]\implies 80\times 5 = 4\times x[/tex]
[tex]\implies 400 = 4\times x[/tex]
[tex]\implies x = \frac{400}{4}[/tex]
[tex]\implies x = 100cm[/tex]
Hence, the height of the taller boy is 100cm.
