Answer:

\frac{3}{8}

Step-by-step explanation:

To make this a fraction, you do \frac{4.5}{12}. This is now a simple division problem. 4.5 ÷ 12 = .375

.375 as a fraction is \frac{375}{1000}. When you simplify, you get \frac{3}{8}

Help with this I don't know how to solve.
Mashcka [7]

Answer:

The answer is \sqrt{105} or approx. 10,25.

Step-by-step explanation:

EG^2=DG*GF \\ EG^2 = ab \\ EG = \sqrt{5*16} \\ EG = \sqrt{80}

Now let's find EF.

EF^2 = GE^2+GF^2 \\ EF^2 = 80+256\\ EF=\sqrt{336}

Now let's finally find DE.

DE = \sqrt{DF^2-EF^2} \\ DE = \sqrt{21^2-336} \\ DE = \sqrt{441-336} \\ DE=\sqrt{105}

\sqrt{105} = 10,2469... = 10,25

CAN SOMEONE HELP ME WITH MY ALGEBRA 1.
Alenkinab [10]

Answer:

-5

Step-by-step explanation:

\frac{7-2^{2}+17}{-14+(2)(5)}

Multiply 2 · 2 = 4

\frac{7-4+17}{-14+(2)(5)}

Subtract 4 - 7 = 3

\frac{3+17}{-14+(2)(5)}

Add 3 + 17 = 20

\frac{20}{-14+(2)(5)}

Multiply 2 · 5 = 10

\frac{20}{-14+10}

Add -14 + 10 = -4

\frac{20}{-4}

Divide 20 ÷ 4 = -5

-5
