Can someone help me understand this?

ASHA 777 [7]

< means 'less than'. 3.5 is less than 4.5, so A is correct. Since -4.5 is NEGATIVE it is less than 0. As for C, since both numbers are negative, it would be the seemingly 'smaller' number that is actually bigger. It may help to think of the numbers on a number line. In the negatives, the numbers start to go in reverse, so the further from 0 a negative number is, the smaller it is. -4.5 IS LESS than -3.5. All answers are correct.

Right angled triangle calc: find a, b=24, c=33.94113

Ksenya-84 [330]

Use the Pythagorean theorem...
a²+b²=c², in this case a²=c²-b²

a²+24²=33.94113²

a²+576=1,152.00031

a²=576.000306

a=24 (If you need the exact number, not rounded, it is 24.0000064)

Verizon [17]

Answer:

$6:2,\,9:3$

Step-by-step explanation:

Given: The ratio of cups of sparkling water to cups of grape juice concentrate is $3:1$ in a recipe for fizzy grape juice.

To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe

Solution:

Equivalent ratios are the ratios that have the same value.

Find two ratios equivalent to $3:1=\frac{3}{1}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 2

$\frac{3(2)}{1(2)} =\frac{6}{2}$

Multiply both numerator and denominator of $\frac{3}{1}$ by 3

$\frac{3(3)}{1(3)} =\frac{9}{3}$

So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are $6:2,\,9:3$
