soln,

from the series,

a = 2

t2 = -6

r = t2/a

=   \frac{ - 6}{2}

= -3

therefore, tn =

{ar}^{n - 1}

=  {2 \times  - 3}^{n - 1}

now,

seventh term =

{2 \times  - 3}^{7 - 1}

=  {2 \times  - 3}^{6}

= 2 \times 729

= 1458

Ivenika [448]

The combined revenue for the movies in scientific notation is  \$ 3.568 \times 10^8.

The given parameters;

  • <em>first revenue made from the movie, = $352,000,000</em>
  • <em>second revenue made from the movie, = $4,800,000</em>

The combined revenue from the movie is calculated by adding the two revenues together as shown below;

Total revenue = $352,000,000  +  $4,800,000

Total revenue = $356800000 =  \$ 3.568 \times 10^8

Thus, the combined revenue for the movies in scientific notation is  \$ 3.568 \times 10^8

Geraldine has 8 cups of sugar. She uses 6 3/5 cups to make a large cake. How many cups of sugar does she have left?
Inga [223]

Answer:

1\frac{2}{5}

Step-by-step explanation:

remaining cups = total cups - used caps

let remaining cups be = x

     total cups = y = 8

      used cups = z= 6\frac{3}{5}

Hence x = y-z

x = 8 - 6\frac{3}{5}

  = \frac{8}{1}  - \frac{33}{5}  = \frac{40-33}{5} = \frac{7}{5} = 1\frac{2}{5}

x= 1\frac{2}{5}

Remaining cups = 1\frac{2}{5}

Given ZW=20. Answer the questions please. ​
djyliett [7]

a) Corresponding angles of similar figures are congruent, so \angle B \cong \boxed{\angle Z}

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is \frac{25}{10}=\boxed{5/2}

c) Since the scale factor is 5/2,

\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}
