Answer:
1
Step-by-step explanation:
Example: 2×1/2=1
.....
94% chance she will win the next fight. 6% chance she will lose. because it is half of 100, you can multiply it by 2, and that is youre percentage.
The given curve is → x²=y, which is a parabola opening upwards and vertex at (0,0).
When it is reflected in x axis ,the curve becomes→ x²=-y
The graph of two curves are shown.
Now the curve ,x²= -y is scaled vertically by a factor of 1/8.
So, the equation of curve becomes ,→ x²= -y × 1/8
→ x² = -y/8
Plotting the graph of →x² = -y/8
The curve will shrink, as scaling is less than 1.
Answer:
<h3>13 years</h3>
Step-by-step explanation:
Let the present age of Alicia be x
Let the present age of her brother be y
Three years ago;
Alicia age = x - 3
Her brother's age = y - 3
If three years ago Alicia was twice as old as her brother Carlos, then;
X - 3 = 2(Y-3)
x-3 = 2y - 6
x = 2y - 3 ...1
In two years time;
Alicias age = x+2
Her brother's age = y +2
If in two more years Alicia will be just 50% older than Carlos, then;
x+2 = y + 2 + (0.5(y+2))
x+2 = y+2 + 0.5y + 1
x+2 = 1.5y+3
x = 1.5y + 1 ...2
Equating 1 and 2;
2y - 3 = 1.5y + 1
2y - 1.5y = 1+3
0.5y = 4
y = 4/0.5
y = 8
Since x = 2y-3
x = 2(8) - 3
x = 16-3
x = 13
Hence Alicia will be 13 years old today
The compound inequality represents the situation is r > 4 and r ≤ 4.1
<h3>Compound inequality</h3><h3 />
- r must be greater than 4 cm
r > 4
r ≤ 4.1
Therefore, r > 4 and r ≤ 4.1 is the compound inequality which represent the situation.
