The height of a certain banner is equal to one third of its length. If the banner is 5 ft tall, write the equation that can be u
pav-90 [236]

Answer:

L=3h

Step-by-step explanation:

Let height of a banner be h, then we know that this is \frac{1}{3} of the length L of the banner; so we have

h=\frac{1}{3} L .

Now we can rearrange this equation to solve for the length of the banner given it's height:

L=3h

So there we have it!

If the banner is 5 ft tall, then it's length will be:

L=3*5=15ft

SVEN [57.7K]

Answer:

Her account balance after 5 years is $8702.87

Step-by-step explanation:

1500 (1.05) = 1575 --> after one year

1575 + 1500 = 3075    

3075 (1.05) = 3228.75 --> after two years

3228.75 + 1500 = 4728.75

4728.75 (1.05) = 4965.1875 --> after three years

4965.1875 + 1500 = 6465.1875

6465.1875 (1.05) = 6788.44688 --> after four years

6788.44688 + 1500 = 8288.44688

8288.44688 (1.05) = 8702.86922 --> after five years = $8702.87

Complete this table showing the number of shaded triangles in each step and area of each triangle!
djverab [1.8K]

Answer:

Step-by-step explanation:

From the table attached we find,

Number of shaded triangles = 1

Area of each shaded triangle = 256 square inches

Now we can complete the table following the same pattern,

Step number     Number of shaded triangles   Area of the shaded triangles

        0                                   1                                                   256

        1                                    3                                  256 × 3 = 768

        2                                   5                                256 × 5 = 1280

        3                                   7                                  256 × 7 = 1792
