Write the fraction or mixed number as a decimal. 1. 8 4/100 2. 4/10 3. 4 7/100 4. 6/10 5. 8 3/100 6. 8/10 7. 4/100 8. 10 14/100

damaskus [11]

8 4/100 = 8.04, as the ".00" is out of 1.00.
4/10 = 0.40
4 7/100 = 4.07
6/10 = 0.60
8 3/100 = 8.03
8/10 = 0.80
4/100 = 0.04
10 14/100 = 10.14
The quick way to determine what the decimal is, is to divide 100 by the denominator. That way, each time the numerator goes up, you can multiply how many times it goes up by the denominator.
I hope this helps!

16t-2(2t+5)=14 7th grade T=? plz helpppp

Zina [86]

16t -2(2t+5) =14

distribute the parenthesis first:

16t-4t-10 = 14

combine like terms:

12t - 10 = 14

add 10 to both sides:

12t = 24

divide both sides by 12

t = 24/12

t = 2

The diagonals of rhombus ABCD intersect at point E. The area of ABCD is 168 in^2 If ED = 8 inches, find AC.

sattari [20]

Area of Rhombus = $\frac{(diagonal 1) * (diagonal 2)}{2}$

Diagonal DB = 2×8 = 16

To find AC, we substitute into the formula the area 168 in² and DB of 16 in

Area = $\frac{DB*AC}{2}$
$168= \frac{16*AC}{2}$
$336=16*AC$
$AC= \frac{336}{16}=21$ inches

Answer: B
