This means overall there are 8 parts to this spinner. Since 5 takes up 3 of these 8 parts, the probability of the pointer landing on 5 is 3/8.

Answers
Answer:
m∠T = 54°
Step-by-step explanation:
The measure of a straight line is 180°. (Linear angles theorem)
So, m∠WMT + 117° = 180°
m∠WMT = 180 - 117 = 63°
The base angles in an isoceles triangle are equal in measure (base angle theorem)
So,
m∠MWT = m∠WMT
m∠MWT = 63°
The sum of angles in a triangle is 180°. (Sum of angles in a triangle theorem) So,
m∠MWT + m∠WTM + m∠WMT = 180°
Substitute the measures we already found.
63 + m∠WTM + 63 = 180
Simplify.
126 + m∠WTM = 180
m∠WTM = 54°
m∠T = 54°
I hope this helps! Feel free to ask any questions!
Answer:
54°
Step-by-step explanation:
First calculate Angle WMT as: 180° - 117° = 63°
And note that Angle WMT = Angle MWT = 63°
Therefore, Angle T = 180° - 63° - 63°
Angle T = 54°

A ranch hand herded his cattle to some grazing land. Then he began riding back to the ranch,
which is due west, at 7 miles per hour. Simultaneously, the cows began moving away from
him, too, headed due east at 3 miles per hour. How long did it take for the herd and the
ranch hand to be 2 miles apart? (Please help me !!)
Answers
Answer:
1/5 hr or 12 min
Step-by-step explanation:
We are going to use the formula D = RT
Let t = the time for them to be 2 mi. apart
Then 7t = the distance the ranch hand traveled
and 3t = the distance the cows traveled
Since they traveled in opposite directions, the sum of their distances will give us how far they are apart.
So, 7t + 3t = 2
10t = 2
t = 2/10 = 1/5 hr. = 12 min.

The basketball coach spent $35 on 5 t shirts for his team last season. This season, he needs to purchase 7 t shirts. If he pays the same rate as last year, how much will the t shirts cost?
Answers
Answer:
5 dollars
Step-by-step explanation:
last year he got 5 they were 7 dollars because 7x5 is 35 so do the same thing to do other it also equals 35
so 35/5
is 7
the next season he needs to have 7,
2 more then the prior season.
we now know each t shirt is the same price as last season it’ll be $7 each.
so you’d multiply 7x7 which is
$49
final answer: $49

A high school drama department sold 238 tickets for their performance.
o An adult ticket cost $6.75.
o A student ticket cost $3.50.
o The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold?
Answers
Ley y = number of nonstudent tickets
then we know that the total number of tickets is 537
so
x + y = 537
if we multiply the cost of a ticket by the number of tickets we can also get the total $
3.2x + 5.9y = 2185.5
now we have two equations and two unknowns and we can find the value for these unknowns
lets use substitution
x + y = 537 that means that x = 537-y
substitute this value in the second equation
3.2(537-y) + 5.9y = 2185.5
1718.4 - 3.2y +5.9y = 2185.5
1718.4 + 2.7y = 2185.5
2.7y = 2185.5 - 1718.4
2.7y = 467.1
y = 173
x + y =537
x + 173 = 537
x = 364
Answer:
$6.75 + $3.50 = X
X ÷ $1,252.25
Step-by-step explanation:
$6.75 + $3.50 = $10.25
$10.25 ÷ $1,252.25 = 0.00818526652
