Will give brainliest answer to whoever gets this correct.

yanalaym [24]

draw an imaginary line down from the 1 dimension so you have a rectangle that is 1 by 24

area = L x w = 24 * 1 = 24 square units

now you have a triangle that is 7 at the bottom and 24 tall

area of triangle = 1/2 x base x height

so you have 1/2 * 7 * 24 which =84 square units

total area = 84 + 24 = 108 units^2

Madison received a share of $4230 for a fishing competition. She deposited it in the bank and left it for 3 years accumulating s

Elis [28]

Answer:

$4785.68

Step-by-step explanation:

Original amount: $4230

Interest for 1 year: 4.2%

First year;

$4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66$

Second year;

$4407.66 + (4407.66 \times \frac{4.2}{100} ) \\ = 4407.66 + 185.12172 \\ = 4592.78172$

Third year (total balance after 3 years);

$4592.78172 + (4592.78172 \times \frac{4.2}{100} ) \\ = 4592.78172 + 192.89683224 \\ =4785.67855224$

Round the number;

$4785.68

The volume of the cone is 294.38 cm the radius of the base is 7.5 cm which one of the following could be the height of the cone?

drek231 [11]

The volume of a cone is 1/3 pi*r^2 * h. Rearranging for height gives h = 3v / pi*r^2 = (3*294.38) / (3.14*7.5^2) = 5.00 (answer B)

Use the functions h(x) = 2x + 5 and t(x) = 7x − 6 to complete the function operations listed below.

wlad13 [49]

We have to use the functions:
h ( x ) = 2 x + 5 and t ( x ) = 7 x - 6
Part A:
( h + t ) ( x ) = ( 2 x + 5 ) + ( 7 x - 6 ) = 9 x - 1
Part B :
( h · t ) ( x ) = ( 2 x + 5 ) · ( 7 x - 6 ) = 14 x² - 12 x + 35 x - 30 =
= 14 x² + 23 x - 30
Part C :
h [ t ( x ) ] = h ( 7 x - 6 ) = 2 · ( 7 x - 6 ) + 5 = 14 x - 12 + 5 =
= 14 x - 7
