Mark and Trisha are traveling in the same direction and Mark is going 16 miles per hour. Trisha is going 12 miles per hour but started 8 miles before Mark. When will they meet up?
Answer:
32 miles
Step-by-step explanation:
Given data
Let the total distance be x miles
Marks speed= 16miles per hour
Trisha's speed= 12 miles per hour
Trisha has covered 8 miles and has (x-8) miles to finish line
We know that
Speed= distance/time
time= distance/speed
Hence the time taken for Mark to finish is
time= x/16---------------1
The time taken for Trisha to finish is
time= (x-8)/12-----------2
equate 1 and 2 above
x/16= (x-8)/12
cross multiply
16(x-8)= 12*x
16x-128= 12x
collect like terms
16x-12x= 128
4x=128
x= 128/4
x= 32 miles
Hence they will meet at exactly 32 miles along the way

Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y + 2 = - 2(x - 3) ← is in point- slope form
with slope m = - 2 → A

Complete Question
If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches
a 33.4 inches
b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
Answer:
d. 39.3 inches
Step-by-step explanation:
We are to find the Arc length of the circle
To solve the above question, the formula is given as:
Arc length = Central angle × radius
From the above Question, we are given:
Central angle = 5pi/6 = 5π/6
Radius = 15 inches
Hence,
Arc length = 5π/6 × 15 inches
Arc length = 235.61944901923448/ 6
Arc length = 39.26990817 inches
Approximately , the Arc length
= 39.3 inches.
Therefore, Option d is the correct answer.

t is an number in the series: 1/t + 3/t + 5/t + ...+ t-1/t a)Determine the number of terms in the series in terms of t. b)Determine the sum of the series in terms of t. c)Hence,or otherwise,evaluate:(1/4+3/4)+(1/6+3/6+5/6)+(1/8+3/8+5/8+7/8)+...+(1/50+3/50+5/50+49/50)
Answer:
Below in bold.
Step-by-step explanation:
1/t + 3/t + 5/t + ...+ t-1/t
This is an arithmetic series in which the common difference is 2/t.
a) The number of terms = [ (last term - first term) / common difference] + 1
= [(t-1)/t - 1/t) / 2/t] + 1
= (t - 2)/t * t/2 + 1
= (t -2)/2 + 1
= (t-2) / 2 + 2/2
= t/2.
b). Sum of the series (n/2)(a + l) where a = first term , n = number of terms and l = last term, so
Sum = (t/2)/2 ( 1/t + (t-1)/t)
= t/4 * 1
= t/4.
c). (1/4+3/4 )+ (1/6+3/6+5/6 )+( 1/8+3/8+5/8+7/8) +...+(1/50+3/50+5/50+49/50)
Using the results from a) and b):
The sum = 4/4 + 6/4 + 8/4 + ......+ 50/4.
= 1 + 1.5 + 2 +...... + 12.5
This is an AS with common difference = 0.5,
Number of terms = [(12.5 -1) / 0.5] + 1
= 23 + 1
= 24, so
Sum = (24/2)(1 + 12.5)
= 12 * 13.5
= 162.
The number of terms is t/2, and the sum of the series is 1/2 - (t - 2)/4
What is an arithmetic sequence?
In an arithmetic sequence, the common difference is the difference between successive terms.
a) From the sequence:
a = 1/t; d = (3/t) - (1/t) = 2/t
The number of terms is:
(t - 1)/t = 1/t + (n - 1)(2/t)
t - 1 = 1 + 2(n - 1)
t = 2n
n = t/2
b) The sum of the series is:
S = (n/2)[2a + (n - 1)d]
S = (t/2/2)[2(1/t) + (t/2 - 1)(2/t)]
S = (t/4)[2/t - (t - 2)/t]
S = 1/2 - (t - 2)/4
The number of terms is t/2, and the sum of the series is 1/2 - (t - 2)/4

Which ratio represents the cotangent of angle B in the right triangle below?
A. 5/3
B. 3/5
C. 3/4
D. 4/3
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4
