ABCD is a rectangle. Rectangle A B C D is shown. All angles are right angles. The length of A D is 5 and the length of D C is 12

sashaice [31]

Answer: 13

Step-by-step explanation:

I used Pythagorean theorem to solve this problem. As DC and AD is 12 and 5, you would do 12²+5²= c². 12²= 144 and 5²= 25. 144+25= 169. It doesn't end there. Do the square root of 169 ---> √169=13.

Answer:

if u have any doubts feel free to ask :)

Step-by-step explanation:

Sum of ratio : 9 + 7 + 4 = 20

Adele share :

$\frac{9}{20} \times 680 = 9 \times 34 = \$ 306$

Barbara share :

$\frac{7}{20} \times 680 = 7 \times 34 =\$ 238$

Collette share :

$\frac{4}{20} \times 680 = 4 \times 34 = \$ 136$

$ €

1.125 1

306 x

$\frac{1.125}{306} = \frac{1}{x}$ [cross multiply]

$x =\frac{ 306} {1.125}$

x = €272

Adele receives = €272

Apple Cost

1 kg 2.69

5 kg y

y = 2.69 x 5 = $13.45

Cost of 5kg of apples = $13.45

Cost of 3 kg bananas = 17.56 - 13.45 = $4.11

Banana Cost

3kg 4.11

1 kg z

$z = \frac{4.11}{3}$

z = $1.37

Cost per kilogram of banana = $1.37

e) Collette share = $136

Half of it on clothes = (1/2) x 136 = $68

(1/5) of her share on books = (1/5) x 136 = 27.20

Balance amount with her = 136 - 27.20 - 68 = $ 40.80

If the mean of the four numbers 2x and 12 is 10, then x is

Lelu [443]

Answer:

Step-by-step explanation:

The mean of 2x and 12 is (2x+12)/2, so we get the equation:

(2x+12)/2 = 10 =>

x+6=10

x = 10-6 = 4

* Your question states four numbers, but you write only two... the answer could be wrong because of that.
