A parallelogram has sides of length 16 units and 10 units. The shorter diagonal is 11 units. Find the measure of the longer diag
lord [1]

The measure of the longer diagonal is 24.31 units

<h3>How to determine the longer diagonal?</h3>

The side lengths are given as;

a = 16

b = 10

The shorter diagonal is represented as d1, and it is given as

d1 = 11

The longer diagonal is represented as d2, and it is calculated using

d1^2 + d2^2 = 2 * (a^2 + b^2)

Substitute the known values in the above equation

11^2 + d2^2 = 2 * (16^2 + 10^2)

Evaluate the sum

121 + d2^2 =2 * 356

Evaluate the product

121 + d2^2 = 712

Subtract 121 from both sides

d2^2 = 591

Take the square root of both sides

d2 = 24.31

Hence, the measure of the longer diagonal is 24.31 units

Kaylis [27]

Answer:

20

Step-by-step explanation:

Because 21.50 x 20 =430

and 18 x 20 = 360

then you add 70 to 360 and you get 430

so Katrina would have to order 20 shirts from each company in order for the cost to be the same.

Is the point (−4,−17) a solution to the inequality 2y−3x&gt;12?
Arturiano [62]

substitute the values for the letters

2(-17) = -34

3(-4) = -12

-34 - -12 = -34 +12 = -22

-22 is not greater than 12 so it is not a solution
