Say we have 1/2 * 1/2. Make a square and cut it in half vertically. Shade one of the halves. Then, cut the square horizontally and shade in half of the shaded area. There we go!

You can count the numbers shaded over the total numbers in the model

In ΔCDE, the measure of ∠E=90°, the measure of ∠D=23°, and EC = 1.3 feet. Find the length of DE to the nearest tenth of a foot.

BabaBlast [244]

Answer: length of DE is about 3.3 ft

Step-by-step explanation: A calculator is necessary!

DE is the unknown hypotenuse of the triangle

get the sine of 23° = 0.3907311285

Use the equation for sine

sin = o/h .

To find h, Substitute values for sin and o. O is EC, Opposite the 23° angle D

0.3907311285 = 1.3/h multiply both sides by h

h(0.3907311285) = 1.3 divide both sides by 0.3907311285

h = 1.3/0.3907311285

3.327096065 = h, the length of the hypotenuse, DE.

Select a number that can complete the equation so that it has no solution. 6(x-7/6)=6x+__

BlackZzzverrR [31]

$6(x - \frac{7}{6} ) = 6 x - 7 \\ 6x - 7 = 6x + ( - 7)$
The answer is the third option, -7.

Hope this helps.
