Answer:

The answer would be 8.7

Step-by-step explanation:

First, you would start with the parentheses. So add 32+8.3 to get 40.3.

The equation will look like this: 49-40.3

The final step would be subtraction.

49-40.3= 8.7

You will get 8.7 as your answer!

I hope this helps!! ;-)

Dominik [7]

Answer:

120 ml oil

150g onions

1.2 kg potatoes

1.5 litres milk

Step-by-step explanation:

The revipe serves 4 people, but Richard wants to serve 12 people. This is 3x the number of people intended.

So, multiply all the fiven ingredients by 3 as well.

Oil = 40ml x 3 = 120ml

Onions = 50g x 3 = 150g

Potatoes = 400g x 3 = 1200g = 1.2 kg

Milk = 500ml x 3 = 1500ml = 1.5 litres

Hope this helps

Solve for x. whats the solutions from least to greatest. 4x^2 + 48x + 128 = 0

Anastasy [175]

Answer:

$\boxed{\sf \ \ \ x = -8 \ or \ x = -4 \ \ \ }$

Step-by-step explanation:

Hello,

$4x^2+48x+128=0\\ 4(x^2+12x+32)=0\\ x^2+12x+32=0\\ (x+6)^2 - 36 + 32= 0\\\\ (x+6)^2-4=0\\ (x+6+2)(x+6-2)=0\\ (x+8)(x+4) = 0\\ x = -8 \ or \ x = -4$

Find the missing length indicated. A) 48 B) 36 C) 100 D) 64

alexandr402 [8]

Answer:

Option D) 64

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle BCD find BC

Applying the Pythagoras Theorem

$BC^{2}=48^{2}+36^{2}\\BC^{2}=3,600\\BC=60\ units$

In the right triangle ABC

$cos(C)=BC/AC$

substitute the values

$cos(C)=60/(x+36)$ -------> equation A

In the right triangle BDC

$cos(C)=CD/BC$

substitute the values

$cos(C)=36/60$ -------> equation B

equate equation A and equation B

$60/(x+36)=36/60\\ \\(x+36)*36=60*60\\ \\36x+1,296=3,600\\ \\36x=3,600-1,296\\ \\36x=2,304\\ \\x=64\ units$
