Answer:

Base = 10 cm

Height = 60 cm

Step-by-step explanation:

The formula for the area of a triangle is  area=\frac{1}{2} *b*h , where <em>b</em> is the length of the base of the triangle, and <em>h</em> is the length of the height of the triangle.

We know the area is 300, and since the height of the triangle is 6 times its base, we know that h=6*b. We can plug in these values into our formula for the area of a triangle, which gives us the following equation to solve:

300=\frac{1}{2} *b*(6*b)

3b^2=300

b=\sqrt{100} =10

The base of the triangle is 10 centimeters.

Now that we know the base of the triangle, we can plug its value in to the original formula to solve for the height of the triangle, which gives us the following equation:

300=\frac{1}{2} *10*h

5h=300

h=60

The height of the triangle is 60 centimeters.

Solve for k. k/2 +1/2=3
ikadub [295]

Answer:

k = 5

Step-by-step explanation:

Solve for k :

\frac{k}{2} + \frac{1}{2} = 3

-Multiply both sides of the equation by the denominator 2 :

2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2

k + 1 = 6

-Subtract both sides by 1:

k + 1 - 1 = 6 - 1

k = 5

So, the value of k is 5.

givi [52]

Answer:

y = 3x + 1

Step-by-step explanation:

Since we know the Graph is Parallel to y = 3x + 11, we know that the "mx" portion of the equation is 3x since only the "b" would be different.

Then we just substitute in the point and to find b.

4 = 3(1) + b

b = 1

y = 3x + 1  is the answer

Use the model below to estimate the average annual growth rate of a certain country's population for 1950, 1988, and 2010, where
Morgarella [4.7K]

Answer:

The average annual growth rate of a certain country's population for 1950, 1988, and 2010 are 2.398, 0.9985 and 0.2236 respectively.

Step-by-step explanation:

The given equation is

Y=-0.0000084x^3+0.00211x^2-0.205x+8.423

Where Y is the annual growth rate of  a certain country's population and x is the number of years after 1900.

Difference between 1950 and 1900 is 50.

Put x=50 in the given equation.

Y=-0.0000084(50)^3+0.00211(50)^2-0.205(50)+8.423

Y=2.398

Therefore the estimated average annual growth rate of the country's population for 1950 is 2.398.

Difference between 1988 and 1900 is 88.

Put x=88 in the given equation.

Y=-0.0000084(88)^3+0.00211(88)^2-0.205(88)+8.423

Y=0.9984752\approx 0.9985

Therefore the estimated average annual growth rate of the country's population for 1988 is 0.9985.

Difference between 2010 and 1900 is 110.

Put x=110 in the given equation.

Y=-0.0000084(110)^3+0.00211(110)^2-0.205(110)+8.423

Y=0.2236

Therefore the estimated average annual growth rate of the country's population for 2010 is 0.2236.
