what is the vaule of x ?

Answer:

area = 88 yd²

Step-by-step explanation:

area = 1/2(b1 + b2)h = 1/2(9 + 13)(8) = 88 yd²

Answer:

88 yd^2.

Step-by-step explanation:

Area of a trapezoid = 1/2 * h * (a + b) where h = height, a and b are lengths of 2 parallel side.

Area = 1/2 * 8(9+13)

= 4 * 22

= 88 yd^2.

Answer:

28

Step-by-step explanation:

For Luis to get a mean of 20 he would need:

14 + 18 + 15 + 25 + x (unknown number of goal he needs) / 5 = 20

Therefore 14 + 18 + 15 + 25 + x = 100

Solve for x to get 28

I,,,,M SORRYI NEED POINTSSS

Step-by-step explanation:

Answer:

Sam had 80 dollars in his pocket. He was feeling generous, so he handed out equal amount of money to each of his friends. After he handed out the money, he had 53 dollars left. How much did Sam give out to each one of his friends?

Step-by-step explanation:

In this real-world problem, the money he had at the beginning resembles the 80 in the equation. The -3x is the money he gives out to each of his friends. The 53 on the right-hand side is the money he has left after he gives the money away.

Answer:

y=3x+20

Step-by-step explanation:

So first, I don't like fractions so I would multiply the whole equation by 4. This will make the equation 3x+y=20. Then you have to isolate the y to find the answer so you should subtract 3x from both sides. This will make the equation look like this y=-3x+20. Therefore, y=3x+20

Answer:

Change in water level over thr period Given is 11.16 mm

Step-by-step explanation:

The change in water level. In the part of the river observed will be ;

Water level. = The rate of change in water level per year * period

Rate of change in water level = 1.8mm /year

Number of years = 6.2

The change in water level is thus :

1.8 mm / year * 6.2 years

= (1.8 mm / year * 6.2

= 11.16 mm

--> Actually, Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes.

These shapes have only 2 dimensions, the length and the width.

( based on what i know )

Answer:

you do pythagorean theorem

Step-by-step explanation:

the base is 8 and the side length is 6 so you do 8²+6²

8²=64 +6²=36

64+36=100 you have to square 100 which is 10

C=10

Answer:

d = 4

Step-by-step explanation:

Given f varies inversely as d² then the equation relating them is

f = [tex]\frac{k}{d^2}[/tex] ← k is the constant of variation

To find k use the condition when d = 2, f = 6 , then

6 = [tex]\frac{k}{2^2}[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

24 = k

f = [tex]\frac{24}{d^2}[/tex] ← equation of variation

When f = 1.5 , then

1.5 = [tex]\frac{24}{d^2}[/tex] ( multiply both sides by d² )

1.5d² = 24 ( divide both sides by 1.5 )

d² = 16 ( take the square root of both sides )

d = [tex]\sqrt{16}[/tex] = 4

Answer:

y - 9 = -3/2 (x - 6)

Step-by-step explanation:

Equation of line: 4x - 6y - 15 = 0

Equation of perpendicular line: bx - ay + k = 0

                                                 = -6x - 4y + k = 0 → (equation 1)

Since the equation passes through (6,9)

-6(6) - 4(9) + k = 0

-36 -36 + k = 0

-72 + k = 0

k = 72

Substituting the value of in equation 1,

∴ Equation of perpendicular line = -6x -4y + 72 = 0

dividing by -2,

3x + 2y - 36 = 0

This equation is the simplified version of Option 1.

y - 9 = -3/2 (x - 6)

y - 9 = (-3x + 18)/2

2y - 18 = -3x + 18

3x + 2y - 36 = 0

Answer:

6

Step-by-step explanation:

The function is of the form

y =a f(bx) where |a| is the amplitude and b is the frequency

y = 6 sin (3x)

The amplitude is |6| = 6

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The area is calculated as width × length , that is

[tex]\frac{50\sqrt{3} }{\sqrt{2} }[/tex] × [tex]\frac{80\sqrt{5} }{\sqrt{3} }[/tex] ( cancel [tex]\sqrt{3}[/tex] on numerator/ denominator

= [tex]\frac{50}{\sqrt{2} }[/tex] × 80[tex]\sqrt{5}[/tex]

= [tex]\frac{4000\sqrt{5} }{\sqrt{2} }[/tex]

To rationalise the denominator multiply numerator/denominator by [tex]\sqrt{2}[/tex]

= [tex]\frac{4000\sqrt{6} }{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex]

= [tex]\frac{4000\sqrt{10} }{2}[/tex]

= 2000[tex]\sqrt{10}[/tex] → C

y = (2x + 1)/(3x + 4)

y(3x + 4) = (2x + 1)

3xy + 4y = 2x + 1

4y - 1 = 2x - 3xy

4y - 1 = x(2 - 3y)

x = (4y - 1)/(2 - 3y) , answer = E
