1 answer:

4 0

Try this option:
according to the condition w+l=48 and w*l=95.
Using these two equation:
$\left \{ {{l+w=48} \atop {lw=95}} \right. \ =\ \textgreater \ \ \left[\begin{array}{ccc}l=24- \sqrt{481};w=24+ \sqrt{481}\\ \\l=24+ \sqrt{481};w=24- \sqrt{481}\end{array}$

The circumference of a circle is about 50 centimeters (cm). Which is closest to the length of its radius? You may use 3.14 for

Romashka-Z-Leto [24]

Answer:

8 cm

Step-by-step explanation:

The formula of circumference is c= πd------(1)

where C = circumference, π = 3.14 and d = diameter

as we know that diameter is equal to d= 2r

put the diameter formula in eq(1)

we get c= π2r-------(2)

from eq (2) separate r means radius

hence, r= c/(π2)------(3)

put the values in eq(3)

and radius is equal to 8 cm.

If 32% of a number is 64 what is the number

Vladimir [108]

Step-by-step explanation:

Let the required number be x

$32\% \: of \: x = 64 \\ \\ \frac{32}{100} \times x = 64 \\ \\ x = 64 \times \frac{100}{32} \\ \\ x = 2 \times 100 \\ \\ x = 200$

Thus, the required number is 200.
