Hassan sells fruit and vegetables at the market.
Juli2301 [7.4K]

Answer: 950 kg

Step-by-step explanation:

Given

Hassan sells a total of 1.33\ \text{tonnes} of vegetables

The ratio of the mass of fruit to the vegetables is 5:7

Suppose x\ \text{tonnes} is the total mass of stuff

For vegetables, we can write

\Rightarrow x\times \dfrac{7}{5+7}=1.33\\\\\Rightarrow x=1.33\times \dfrac{12}{7}=2.28\ \text{tonnes}

For fruits

\Rightarrow 2.28\times \dfrac{5}{5+7}=0.95\ \text{tonnes}\approx 950\ kg

INTELLIGENT STUDENT IN TRIG?.Ill give brainlest​
faltersainse [42]

Answers:

x = 6

y = 6*sqrt(2)

=======================

Explanation:

To find these values, you can use the general template of a 45-45-90 triangle or you can use trig ratios

tan(45) = 1

tan(angle) = opposite/adjacent

tan(45) = x/6

1 = x/6

6*1 = x

x = 6

-------

sin(45) = 1/sqrt(2)

sin(angle) = opposite/hypotenuse

sin(45) = 6/y

1/sqrt(2) = 6/y

1*y = sqrt(2)*6

y = 6*sqrt(2)
