Answer:
x = tex]5\frac{\textup{7}}{\textup{8}}\ in[/tex]
Step-by-step explanation:
Given:
Total height of the bench = 18 in
Depth of the stone bench =
=
= 3.375 in
Measure of stones =
=
= 3.5 in
measure of another stone =
=
= 5.25 in
let the height of the third stone be 'x'
Now,
The total height of the bench = depth of bench + Measure of two stones + x
18 = 3.375 + 3.5 + 5.25 + x
or
x = 18 - 12.125
or
x = 5.875 in
or
x = tex]5\frac{\textup{7}}{\textup{8}}\ in[/tex]
Answer:
D 12.57
Step-by-step explanation:
diameter = 4inches hence radius = 2inches
if the crust covers the full pizza "around", technically its the circumfrence
hence 2πr
2×π×2= 12.566 ~ 12.57
total bill before any discounts $13.
she is a student, so she gets 20% off.
she brought an item of clothing, so she gets 5% off.
so she's really getting 20% + 5% off, namely 25% off her bill.

Answer:
-2/45
Step-by-step explanation:
-3/5 - (-5/9)
Subtracting a negative is like adding
-3/5 + 5/9
Get a common denominator of 45
-3/5*9/9 + 5/9 *5/5
-27/45 + 25/45
-2/45
1) ABF & EBD ARE SUPPLEMENTARY ANFLES (ABF + EBD =180)
2) FED=?. Note that FED=GEC=(16x-8).
Now in Triangle FED, the relation is (16x-8) + 35 + (2x+9) =180
hence x=8 & DEF=120
