)) The perimeter of the surface of a rectangular table is 18 feet. The table is 3 feet wide. How long is it?
Answer:
6 feet long
Step-by-step explanation:
Perimeter = (2 * length) + (2 * width)
18 = (2 * length) + (2 * 3)
18 = (2 * length) + 6
2 * length =18 - 6
2 length = 12
length = 12/2
length = 6

There were 203 tickets sold for a wrestling
match. For activity card holders the price was
$1.25 and for non-card holders the price was
$2.00. The total amount of money collected was
$310. How many of each type of tickets were
sold?
Answer:
the number of activity card holders is 128 and non-card holders is 75 respectively
Step-by-step explanation:
Let us assume the activity card holders be x
And, the non-card holders be y
Now as per the given situation
x + y = 203
x = 203 - y
1.25x + 2y = 310
Now put the value of x in the above equation
1.25(203 - y) + 2y = 310
253.75 - 1.25y + 2y = 310
0.75y = 56.25
y = 75
And,
x = 203 - 75
= 128
Hence, the number of activity card holders is 128 and non-card holders is 75 respectively

\angle DAC=\angle BAD∠DAC=∠BADangle, D, A, C, equals, angle, B, A, D. What is the length of \overline{AC} AC start overline, A, C, end overline? Round to one decimal place. Stuck
Answer:
AC = 4.5 units
Step-by-step explanation:
Given question is incomplete without the figure; find the figure attached.
By applying angle bisector theorem in the given triangle ABC,
(Since, AD is the angle bisector of ∠BAC)
[tex]\frac{AC}{CD}=\frac{AB}{BD}[/tex]
[tex]\frac{AC}{2.5}= \frac{6.8}{3.8}[/tex]
AC = [tex]\frac{6.8\times 2.5}{3.8}[/tex]
AC = 4.47
AC ≈ 4.5 units
Length of side AC in the given triangle = 4.5 units.
