pretty please help me!!! i’ll mark brainliest! i tried putting this at 13 points!
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°

Answer:
The equation of the line is y=-1/2x-3.5
Step-by-step explanation:
Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].
[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]
After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.
[tex]-4=\frac{-1}{2} (1)+b[/tex]
[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex] add both sides by 1/2 so that b is alone
[tex]\frac{-7}{2} =b[/tex]
You can rewrite -7/2 as -3.5.
what does the 50th term of this arithmetic sequence: 29,32,35,38
Answer:
176
Step-by-step explanation:
First term (a) = 29
Common difference (d) = 32 - 29 = 3
For calculating the 50th term , n = 50
Now
[tex]t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176[/tex]
hope it will help :)

If f(1)=6 and f(n)=f(n-1)+2 then find the value of f(6)
Answer:
Step-by-step explanation:
Answer:
f(6) = 16
Step-by-step explanation:
In the next steps we use this formula : f(n)=f(n-1)+2
Since f(1)=6 then f(2)=f(2-1)+2 = f(1)+2 = 6+2 = 8
f(2)=8 then f(3)=f(3-1)+2 = f(2)+2 = 8+2 = 10
f(3)=10 then f(4)=f(4-1)+2 = f(3)+2 = 10+2 = 12
f(4)=12 then f(5)=f(5-1)+2 = f(4)+2 = 12+2 = 14
f(5)=14 then f(6)=f(5-1)+2 = f(4)+2 = 14+2 = 16.
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 !!)
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.

a school is having a competition to see who can read the most books in one month (30 days). In the first 5 days, Jake reads 4 books. Meanwhile, Amy reads 5 books over 6 days. If they continue at these rates, who will win? By how many books?
Answer:
Amy will winStep-by-step explanation:
Jake
4 books ⇔ 5 days
x books ⇔ 30 days
5x = 4*30x = 120/5x = 24 booksAmy
5 books ⇔ 6 days
x books ⇔ 30 days
6x = 5*30x = 150/6x = 25 booksAmy will win by 25 - 24 = 1 book

Answer:
a = 30
2a = 60
3a = 90
Step-by-step explanation:
3a + 2a + a = 180 ( Sum of angles of a triangle is 180)
6a = 180
a = 180/6
a = 30
2a = 2 x 30 =60
3a = 3 x 30 = 90

Finley's pumpkin had a mass of 6.5 kilograms (kg) before he carved it. After carving it, the pumpkin had a mass of 3.9 kg
Answer:
[tex]\%Change = -40\%[/tex]
Step-by-step explanation:
Given
[tex]Initial = 6.5kg[/tex]
[tex]Final = 3.9kg[/tex]
Required
Determine the percentage change --- Missing from the question
This is calculated as
[tex]\%Change = \frac{Final - Initial}{Initial} * 100\%[/tex]
[tex]\%Change = \frac{3.9kg - 6.5kg}{6.5kg} * 100\%[/tex]
[tex]\%Change = \frac{-2.6kg}{6.5kg} * 100\%[/tex]
[tex]\%Change = \frac{-260}{6.5}\%[/tex]
[tex]\%Change = -40\%[/tex]
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?
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

Answer:
19 Dollars
Step-by-step explanation:
Discount means that a certain percentage of the price is being deducted from the final price. So, it this case, we first have to find 5% of 20. 5% of 20 is 1 because 20 * .05 is one. Then, we just have to deduct 1 dollar from 20 dollars, making it 19 dollars.

Pam bought 20 pieces of fruit for her class.
o Each piece of fruit was either an apple or an orange.
o She spent $1.25 on each apple.
o She spent $0.95 on each orange.
o Pam spent a total of $22.60.
Write a system of equations that can be used to find the number of apples Pam bought. Make sure to define your variables.
Choose the correct define variables and the correct system of equations
Answer:
Step-by-step explanation:
Let O=number of oranges and A=number of apples.
O+A=20
O=20-A
1.25A+0.95O=22.60, using O found above makes this become
1.25A+0.95(20-A)=22.60
1.25A+19-0.95A=22.60
0.3A+19=22.60
0.3A=3.6
A=12, since O=20-A
O=20-12
O=8
So she bought 8 oranges and 12 apples. The question really only asks for the number of apples bought.
12 apples were bought.
Answer:
1.25x+0.95y=22.60
x is apples y is oranges
Step-by-step explanation:
20 - 12 = 8
1.25(12) + 0.95(8) = 22.60
1.25 · 12 = $15
0.95 · 8 = $7.60
15.00 + 7.60 = $22.60
i hope that makes sense
