Write an equation and solve.
How opd am I if 400 reduced by 2 times my age is 244?

Answer:

30%

Step-by-step explanation:

3/10=30/100 and 30/100 is the same as 30%

because %'s mean out of 100 so 30% means 30 out of 100 which can be simplified to 3 out of 10 or 3/10 (so its all equal)

Answer:

3%

Step-by-step explanation:

Answer: [(3/4)π] in² or (0.75π) in²

Step-by-step explanation:

Here, we are asked to find the area of a sector. So we are going to use the formula: A=πr²(θ/360)

--------------------------------------------------------------

Given

r=3 in

θ=30°

Solve

A=πr²(θ/360)

A=π(3)²(30/360)

A=9π(1/12)

A=[(3/4)π] in²

A=(0.75π) in²

Answer:

B.17.5cm²

Step-by-step explanation:

S=a+b+c/2=

5+8+7/2=10

S=10

Area of the triangle=[tex]\sqrt{3(5-a)(5-b)(5-c)}[/tex]

⇒[tex]\sqrt{10(10-5)(10-8)(10-7)}[/tex]

⇒[tex]\sqrt{10*5*2*3}[/tex]

⇒[tex]\sqrt{300}[/tex]

⇒17.5cm²

∠IJG = ∠FGE (they are corresponding angle)

So, ∠FGE = 50°

Answer:

∠FGE is also 50°

Step-by-step explanation:

they are corresponding angles.

Answer:

to find the value of x have to know that they would all add up to 180 degrees. so subtract 98 from 180. then you would have to find the angel of the part on the left.

Step-by-step explanation:

Answer:

X = 41

Step-by-step explanation:

this triangle is isosceles triangle, so

X + X + 98 = 180 ( being triangle)

2X + 98 = 180

2X = 82

therefore : X = 41

Answer:

A

Step-by-step explanation:

Yoy get A by combining like terms.

Answer:

When x < 0 (Option 1)

Step-by-step explanation:

The answer to your question would be Option 1, or when x < 0. When you create a table with f(x) and g(x), they're only ever equal when x = 0, which is when f(x) and g(x) both equal 1. When the numbers go into negatives for each equation, f(x) becomes exponentially bigger. Making f(x) > g(x) true when x < 0.

Hope this helps!

Answer:

The answer is 16 feet

Step-by-step explanation:

You do 1.5 feet times 4 hours and you get 6 feet and than you add 10 and 6 and you get 16 feet after 4 hour.

Answer:

Approximate length of line AB is 8.6

Step-by-step explanation:

Input Data :

Point 1 (xA, yA) = (8, 2)

Point 2 (xB, yB) = (3, 9)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB − xA) ^2 + (yB − yA)^2

Solution :

Distance between two points = √(3 − 8) ^2 + (9 − 2) ^2

= √(−5) ^2 + 7^2

= √25 + 49

= √74

= 8.6023

Distance between points (8, 2) and (3, 9) is 8.6023

hope this helps and is right :)

Answer:

First choice

12.0

Step-by-step explanation:

Make a right triangle, drawing straight lines, down from point A and left from point B. Use the pythagorean theorum to solve.

I will use "x," "y," and "z" as sides of the triangle as to not confuse between points a and b.

Line AB is line z

x^2 + y^2 = z^2

8^2 + 9^2 = z^2

64 + 81 = z^2

145 = z^2

(find square roots of both)

12.0416 = z

Answer:

25.13 m/s

Step-by-step explanation:

Linear velocity = Distance / time

The distance = Circumference of turbine = 2πr

Radius, r = 40 m

Circumference= 2 * π * 40 = 251.327

The linear velocity is thus :

Circumference / time

= 251.327m / 10s

= 25.13 m/s

Answer:

x = 10

Step-by-step explanation:

Since both equations give y in terms of x, equate the right sides

3x - 28 = - 2x + 22 ( add 2x to both sides )

5x - 28 = 22 ( add 28 to both sides )

5x = 50 ( divide both sides by 5 )

x = 10

Answer:

N = 30

Step-by-step explanation:

30 divided by 10 is three. Three plus three equals 6.

Answer:

yes

Answer:

is this the full question?

Step-by-step explanation:

Answer: x=120°

Step-by-step explanation:

What you are looking for is the value of the exterior angle of the regular polygon.

For a n-sided regular polygon, the external angle is given by the formula 360°/n.

Because the shape in this example is a regular triangle, the value of n is 3.

360°/n

=360°/3

=120°

Therefore, x=120°

Answer: 20.989353895 or round it up to 21

Step-by-step explanation:

If we want to find a diameter of a circle and given a circumference, we divide the circumference by pi

so 65.94 divide by pi = 20.989353895
