at present Ankit is twice as old as his son in four years he will be four times as old as what his son was 9 years ago find the present years of both of them
Answer:
His son present age is 20 years
His present age is 40 years
Step-by-step explanation:
Assume that this son's age now is x years
∵ His son's age now = x years
∵ Ankit age is twice as old as his son
→ Twice means × 2
∴ Ankit age = 2 × x = 2x years
→ In for years means after 4 years (add)
∵ His age in four years = 2x + 4
→ 9 years ago means before 9 years (subtract)
∵ His son 9 years ago = x - 9
∵ In 4 years he will be four times as old as what his son was 9 years ago
→ That means 2x + 4 = 4 × (x - 9)
∴ 2x + 4 = 4(x - 9)
→ Let us solve the equation to find x
∴ 2x + 4 = 4(x) - 4(9)
∴ 2x + 4 = 4x - 36
→ Subtract 4 from both sides
∵ 2x + 4 - 4 = 4x - 36 - 4
∴ 2x = 4x - 40
→ Subtract 4x from both sides
∵ 2x - 4x = 4x - 4x - 40
∴ -2x = -40
→ Divide both sides by -2
∵ [tex]\frac{-2x}{-2}[/tex] = [tex]\frac{-40}{-2}[/tex]
∴ x = 20
∵ x represents the present age of his son
∴ His son present age is 20 years
∵ 2x represents his present age
∵ 2(20) = 40
∴ His present age is 40 years
You are on a boat in the ocean, at point A. You locate a lighthouse at point D, beyond the line of sight of the marker at point C. You travel 90 feet west to point B and then 36 feet south to point C. You travel 100 feet more to arrive at point E, which is due east of the lighthouse. What is the distance from point E to the lighthouse?
Answer:
Step-by-step explanation:
Step-by-step explanation:
Since, after making the diagram of this situation,
We get two triangles ABC and CED,
In which AB = 90 feet, BC = 36 feet and CE = 100 feet,
Now,
( Vertically opposite angles )
( Right angles )
By AA similarity postulate,
By the property of similar triangles,
Since, point D represents the lighthouse.
Hence, the distance from point E to the lighthouse = 250 feet

A dolphin was swimming 4 feet below sea level. The number line shows the
location of the dolphin. It then dove down 3 feet Describe how to use the
number line to find the new location of the dolphin
Answer:
-4+(-3)= -7. The dolphin is -7 feet below sea level
Step-by-step explanation:
Start at -4 on the number line. When you add a negative number to a negative number, you move left on the number line. Move 3 units to the left to land at -7. The dolphin is 7 feet below sea level.
A sample of 12 cars was taken, and the horsepower to miles per gallon was recorded. The computer output for regression is below:
A: y = 6.28 +0.07x
B: y= 0.07 + 6.28x
C: y = 7.47 -2.85x
D: y = -0.20 + 46.92x
E: y = 46.92-0.20x
Answer:
From the given output, the regression equation for the line is
ycap = 46.92 - 0.20x
Option D
The regression equation of the sample of 12 cars from the computer output is (e) y = 46.92 - 0.2x
How to determine the regression equation?From the computer output, we have the following parameters
Intercept = 46.92
Horsepower = -0.20
The above means that the regression equation is:
y = Horsepower * x + Intercept
So, we have:
y = -0.2x + 46.92
Rewrite as:
y = 46.92 - 0.2x
Hence, the regression equation of the sample of 12 cars is (e) y = 46.92 - 0.2x

WILL GIVE BRAINLIEST!! Rhombus ABCD has perimeter 148, and one of its diagonals has length 24. How long is the other diagonal?
The measure of the other diagonal of the Rhombus ABCD will be 35 units.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Rhombus ABCD has a perimeter of 148. Then the length of each side of the rhombus is calculated as,
P = 4a
148 = 4a
a = 37 units
And one of its diagonals has a length of 24. Then the length of the other diagonal is given as,
(37)² = (d / 2)² + (24 / 2)²
1369 = d² / 4 + 144
d² = 1225
d = 35 units
The measure of the other diagonal of the Rhombus ABCD will be 35 units.

Step-by-step explanation:
Vector u has a run of -2 and a rise of -2.
u = <-2, -2>
Vector v has a run of 0 and a rise of -4.
v = <0, -4>
Therefore:
v − 2u
