antiseptic1488 [7]

<u>Given</u>:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

<u>Total cost of the bike:</u>

Let x denote the total cost of the bike.

The total cost of the bike is given by

$30\% \ of \ x=150$

The value of 30% can be written as $\frac{30}{100}$

Thus, we get;

$\frac{30}{100} \times x=150$

Multiplying both sides by $\frac{100}{30}$ , we have;

$x=150 \times \frac{100}{30}$

Simplifying, we have;

$x=\frac{15000}{30}$

$x=500$

Thus, the value of x is 500.

Hence, the total cost of the bike is $500.

Answer:

The Answer is likely 60.

Step-by-step explanation:

Two standard deviations from 70 is 60, because the actual deviation is 5, so 2 of those equals 10. 10 - 70 = 60.

20 POINTS * A circle has a radius of 6. An arc in this circle has a central angle of 48°

storchak [24]

Answer:

$\frac{8\pi}{5}$

Step-by-step explanation:

Since this is a degree we going to use the arc length formula

$2\pi \times( r)( \frac{x}{360)}$

where x is the central angle measure and r is the radius.

The radius is 6 and the central angle is 48 so let plug that in the formula

$2\pi \times (6)( \frac{48}{360} )$

Multiply 2 pi by 6

$12\pi \times ( \frac{48}{360} )$

$12\pi \times \frac{4}{30}$

$\frac{12\pi}{1} \times \frac{4}{30} = \frac{48\pi}{30}$

$\frac{8\pi}{5}$
