Last month, when Joe took his puppy to the veterinarian, the puppy weighed 5.4 pounds. This month, the puppy weighed 7.56 pounds
tino4ka555 [31]

<u>Answer:</u>

40%

<u>Step-by-step explanation:</u>

We are given that last month, Joe's puppy weight 5.4 pounds while this month, the puppy weighed 7.56 pounds.

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

<em>Percentage increase = (new value - initial value)/initial value × 100</em>

So substituting the given values to get:

Percentage increase in puppy's weight = \frac{7.56-5.4}{5.4} \times 100 = 40%

In isosceles trapezoid JKLM, m∠J = 17x + 7, and m∠M = 11x + 13. Find m∠K.
tensa zangetsu [6.8K]

Answer:

m\angle K \approx 104.14^{\circ}

Step-by-step explanation:

In isosceles trapezoid JKLM,

Given: m\angle J = 17x+7 and m\angle M = 11x+13

Since, JKLM is an isosceles trapezoid so each pair of base angles is congruent.

m\angle J = m\angle K

m\angle M = m\angle L

As, we know that the sum of the angle of a trapezoid is 360^{\circ}

The angles are:

m\angle J = 17x+7

m\angle K = 17x+7

m\angle L = 11x+13

m\angle M = 11x+13

Therefore,

17x+7+17x+7+11x+13+11x+13 = 360^{\circ}

Combine like terms;

56x + 40 = 360^{\circ}

Subtract 40 from both sides we get;

56x + 40 -40 = 360 - 40

Simplify:

56x = 320

Divide both sides by 56 we get;

x = \frac{320}{56} = \frac{40}{7}

To find the angle of m\angle K:

m\angle K = 17x + 7 = 17(\frac{40}{7}) +7 = 97.14 + 7

Simplify:

m\angle K \approx 104.14^{\circ}

Therefore, the value of angle of m\angle K \approx 104.14^{\circ}
