$\huge\boxed{5\%}$

First, divide with a calculator.

$34.65\div 33=1.05$

Now subtract $1$ , which is equivalent to the value of the item, as it is equal to $100\%$ .

$1.05-1=0.05$

Move the decimal two places to the right to convert it to a percentage.

$0.05\longrightarrow\large\boxed{5}$

How many liters of a 40% sugar solution must be mixed with 30 liters of a 60% sugar solution to make a 56 % sugar solution?

konstantin123 [22]

Answer:

7.5 liters of a 40% sugar solution

Step-by-step explanation:

Let

x ----> liters of a 40% sugar solution

Remember that

$40\%=40/100=0.40\\60\%=60/100=0.60\\56\%=56/100=0.56$

we know that

The amount of liters of a 40% sugar solution (x) multiplied by 0.40 plus the amount of liters of a 60% sugar solution (30 L) multiplied by 0.60 must be equal to the total amount of liters mixed (x+30) multiplied by 0.56

$0.40x+0.60(30)=0.56(x+30)$

solve for x

$0.40x+18=0.56x+16.8\\0.56x-0.40x=18-16.8\\0.16x=1.2\\x=7.5\ L$

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc with a le

makkiz [27]

Answer:

135 degrees

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=6\ ft$

substitute

$C=2\pi (6)$

$C=12\pi\ ft$

step 2

Remember that the circumference of the circle subtends a central angle of 360 degrees

using proportion

Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft

$\frac{12\pi}{360^o}=\frac{(9\pi/2)}{x}\\\\x=360(9\pi/2)/12\pi\\\\x=135^o$

Twelve more than 3 times a number is more than the opposite of 11

aleksley [76]

Answer: n > $\frac{-23}{3}$

Step-by-step explanation:

1. So, to understand this you need to understand that the opposite of 11 is -11.

2. Use the formula 3n+12>-11.

3. Subtract 12 from both sides (3n>-23)

4. Divide by 3 on both sides. (n> $\frac{-23}{3}$ )

5. You can go a step further and simplify into -7 $\frac{2}{3}$ .

6. n > $\frac{-23}{3}$
