Answer:

About 20

{19 exactly}

Step-by-step explanation:

Evaluate means find approximate value without exact calculation (usually done with great numbers or with fractions)

-8 is approximately -(2+5) so the sum is about 0

34-14 = 30-10 = 20

20 + 0 = 0

The exact calculation would be:

34 -8 - 14 + 2 + 5 = 34 - 14 - 8 + 7 = 20 - 1 = 19

Mariana [72]

Answer:

400/81 cm²

Step-by-step explanation:

FE : DC

1 : 3

Since area ABCD = 400

s² = 400

s = 20

FE = ⅓(20) = 20/3 cm

IH : FE

1 : 3

IH = ⅓(20/3) = 20/9 cm

Area of HIJK:

(20/9)² = 400/81 cm²

Answer:

U =35.5

Step-by-step explanation:

Since this is a right angle, we can use trig functions

tan theta = opp/ adj

tan U = 5/7

Take the inverse of each side

tan ^-1 tan U = tan ^-1 (5/7)

U = 35.53767779

Round to the nearest tenth

U =35.5

Rob is saving to buy a new MP3 player. For every $11 he earns babysitting, he saves $6. On Saturday, Rob earned $44 babysitting.

Anon25 [30]

Answer:

Rob saved $24 on Saturday.

Step-by-step explanation:

Given:

Rob is saving to buy a new MP3 player.

Money earned in baby sitting = $11

Money saved =$6

First we will find the Percentage of amount he saved.

Percentage of amount he saved can calculated by Amount saved divided by total money earned and then multiplying by 100.

framing in equation form we get;

Percentage of amount he saved = $\frac{6}{11} \times 100 \approx 54.55\%$

Now Given:

Money earned in babysitting on Saturday = $44

We need to find the Money he saved on Saturday.

Money Saved can be calculated by Percentage of amount he saved multiplying by Money earned in babysitting on Saturday and then divided by 100.

framing in equation form we get;

Money Saved on Saturday = $\frac{54.55}{100}\times 44 = \$24$

Hence Rob saved $24 on Saturday.
