Simply -3 3/4 divided by 2 1/2​
Dima020 [189]

Answer:

=-1\frac{1}{2}

Step-by-step explanation:

Given the following question:

-3\frac{3}{4} \div2\frac{1}{2}

In order to find the answer, we first convert the mixed numbers into improper fractions. Then we use KCF (Keep, Change, Flip) and solve.

-3\frac{3}{4} \div2\frac{1}{2}
-3\frac{3}{4} =12+3=-\frac{15}{4}
2\frac{1}{2}=2\times2=4+1=\frac{5}{2}
-\frac{15}{4} \div\frac{5}{2}
-\frac{15}{4} \times\frac{2}{5}
15\times2=30
4\times5=20
=-\frac{30}{20}
-\frac{30}{20} \div10=-\frac{3}{2}
-\frac{3}{2}=3\div2=-1\frac{1}{2}
=-1\frac{1}{2}

Hope this helps.

Triangle DEF was dilated according to the rule DO,(x,y) to create similar triangle D'E'F'.
lord [1]
A dilation is a transformation, with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P'. The center O is a fixed point, P' is the image of P, points O, P and P' are on the same line.

Thus, a dilation with centre O and a scale factor of \frac{1}{3} maps the original figure to the image in such a way that the distances from O to the vertices of the image are \frac{1}{3} times the distances from O to the original figure. Also the size of the image are <span>\frac{1}{3} times the size of the original figure. Also the two resulting figures (i.e. the image and the pre-image are congruent)

Thus in the dilation of triangle DEF, the following are true.</span>
<span>∠F corresponds to ∠F'.

The measure of ∠E' is the measure of ∠E.

△DEF ≈ △D'E'F'</span>
