Kendall and Sophia swam (2n - 12) laps together

<em><u>Solution:</u></em>

Given that, Kendall Swam (n) laps in the pool

To find: Number of laps swam together

From given statement,

Number of laps by Kendall = n

Also, Sophia swam 12 less than Kendall

Therefore, number of laps swam by Sophia is 12 less than the number of laps by Kendall

Number of laps by Sophia = Number of laps by Kendall - 12

Number of laps by Sophia = n - 12

<em><u>How many laps did they swim altogether ?</u></em>

Number of laps swam together = Number of laps by Kendall + Number of laps by Sophia

Number of laps swam together = n + n - 12 = 2n - 12

Thus they swam (2n - 12) laps together

A dealer sold a car to a man and made
fenix001 [56]

Answer:

<u>110.000</u>

<u></u>

Step-by-step explanation:

Selling at a loss of 5% means it was sold for 95% of its purchase value.

If 120.175 equals to 95% then 100%(the purchase value) is 126.500.

120.175/95*100 = 126.500 (plenty of other ways to calculate this, but this is one of the easiest)

So now we change to the dealer's perspective, he sold the car for 126.500 and for him that meant a 15% profit. If the purchase value is 100%, then the sale value is 115% (purchase value+15% profit)

Calculate the purchase value:

126.500/115*100 = 110.000

The dealer bought the car for 110.000, sold it for 126.500, so he made a profit of 16.500 (126.500-110.000) which is a 15% profit (15% of 110.000 is 16.500).

If ∠a = 90°, find the measures of ∠b, ∠c and ∠d.
nydimaria [60]

Answer:

m∠b = 35°

m∠c = 145°

m∠ d = 35°

Step-by-step explanation:

To find m∠b, we use Definition of Supplementary Angles:

180 - (90 + 55) = 35°

To find m∠c, we also use Definition of Supplementary Angles:

180 - 35 = 145°

To find m∠d, we use Vertical Angles Theorem:

m∠b = m∠d = 35°
