Answer:

240

Step-by-step explanation:

it is 4 times the area of these right-angled triangles.

we calculate the area of one, and then multiply by 4 as they are all the same.

the missing side is (using Pythagoras)

17² = 8² + side²

289 = 64 + side²

side² = 225

side = 15

area of one triangle

T = 8×15/2 = 4×15 = 60

the rhombus area is

R = 4×T = 4×60 = 240

At Sam's birthday lunch, Sam and one of her friends each ordered a $4 salad while her other 4 friends each ordered a $6 sandwich

Brrunno [24]

Each person will pay $7 before taxes and tip.

Step-by-step explanation:

Price of salad = $4

Price of two salads = 4*2 =$8

Price of sandwich = $6

As 4 friends ordered sandwiches, therefore,

Price of 4 sandwiches = 6*4 = $24

Price of slice of cake = $3

Total = 2 salads + 4 sandwiches + 1 slice of cake

$Total = 8+24+3$

$Total = $35$

5 friends will split the bill evenly, therefore,

Bill for one person = $\frac{Total\ bill}{No.\ of\ people\ paying}$

Bill for one person = $\frac{35}{5} = \$7$

Each person will pay $7 before taxes and tip.

HELP I'm very bad at story questions lolol

Mila [183]

1ST Piece =======> 2x ======> 2 * 3 ft. ======> 6 ft.

2ND =========> 5x =======> 5 * 3 ft. ======> 15 ft.

3RD ==========> 4 Feet =======> 4 ft.

Sum ======> 25 Feet

Equation:

(2x + 5x) + (4) = 25

Let's solve your equation step-by-step.

2x + 5x + 4 = 25

Step 1: Simplify both sides of the equation.

2x + 5x + 4 = 25

(2x + 5x) + (4) = 25 (Combine Like Terms)

7x + 4 = 25

Step 2: Subtract 4 from both sides.

7x + 4 − 4 = 25 − 4

7x = 21

Step 3: Divide both sides by 7.

7x / 7 = 21 / 7

Answer ========> x = 3

Check:

(2x + 5x) + (4) = 25

2(3) = 6

5(3) = 15

3rd Piece = 4

Sum = 25

6ft. + 15ft. + 4ft = 25

25 = 25

Hope that helps!!!!!!!!!!!!! : )
