Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25

Answer:
PC = 12 , AP = 10
Step-by-step explanation:
For each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, then
(1)
PC = 2 × PF = 2 × 6 = 12
(2)
AP = [tex]\frac{2}{3}[/tex] × AD = [tex]\frac{2}{3}[/tex] × 15 = 2 × 5 = 10

Helppppp distance time graphhhhhh
Answer:
Ralph walked to Sherwood at a constant speed.
Step-by-step explanation:
Any horizontal lines on a distance time graph represent a moment where you are still, so that rules out graph 4 and graph 3. Because Ralph is at a constant speed, the gradient of the line won’t change, meaning the answer has to be Ralph walked to Sherwood at a constant speed.
Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)
Answer:
first use the equation m = y2 - y1 / x2- x1 to get the slope
m = -2 - 2 = -4
m = 3 + 7 = 10 when there is a negative for x1 it turns positive
the slope is -4/10 or -2/5
now plus the info into the point slope equation
y - y1 = m (x-x1)
this is in point slope form y - 2 = -2/5 (x + 7)
This is how to get it in y-intercept form
y -2 = -2/5x + -2.8
now add -2 on both sides to the -2.8
y = -2/5x (Slope) + -0.8 y- intercept
Hopefully this is right becuase this is just what i learned
Step-by-step explanation:
The image shows the angles formed by a pair of scissors. When the scissors are closed, m∠1 = 0°. As the scissors are opened, the measures of all four angles change in relation to each other.
Describe how the measures change as m∠1 increases from 0° to 180°.
Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.
Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.
For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

If CosA= sqrt 3/2, what is TanA?
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3

Step-by-step explanation:
Formula of a triangle:
BH x 1/2 (basically dividing by 2)
B is your base which is the length on the bottom of the triangle and the height is the line that is put in between the triangle. You multiply those then divide by 2 since your multiply 2 with it.

If one person runs 8.1 miles per hour in one direction and another with a speed of 6.3 in an other direction how many hours would have gone by if they are 20.16 miles apart
Answer:
1.4 hours
Step-by-step explanation:
Runner A:
Speed = 8.1 mph
Time, = t
Runner B :
Speed = 6.3 mph
Time, = t
Distance apart = 20.16 miles
Distance = speed * time
Distance of Runner A + Distance of runner B = distance apart
8.1t + 6.3t = 20.16
14.4t = 20.16
t = 20.16 / 14.4
t = 1.4 hours
Number of hours, t = 1.4 hours
Kenney High School’s swimming pool is 25 yards long. The pool has 8 lanes, each of
which is 3 yards wide. The pool is filled to a depth of 6 feet.
a. What are the length and width of the pool in terms of feet? (4 points)
Length: __________ ft.
Width: __________ ft.
b. How many cubic feet of water are in the pool? (3 points)
Volume: __________ ft3
c. If one cubic foot contains about 7.5 gallons, how many gallons of water are in
the pool? (3 points)
Water: __________ gallons
Answer:
Length = 75 ft
Width = 72 feet
Volume = 32,400 ft3
Water is around 242,998 gallons
Step-by-step explanation:
Just convert the yards to feet
25 yards long = 75 ft in length
8 lanes * 3 yards wide = 24 yards = 72 feet wide
And then for the volume, since it's a swimming pool, the formula will be l*w*h, and if we plug in the numbers (75 * 72 * 6 (it's 6 because they said the depth was six and in a pool the depth = height)) and that'll equal 32,400 ft to the third power
For the water, we just have to multiply the volume by 7.5 gallons by converting 7.5 gallons to feet, and then multiplying that by the volume, and then converting that to feet, and the final answer is about 242,998 gallons
Answer:
Length; 75 ft
Width; 72 feet
Volume; 32,400
Water is around 243k gallons

[ URGENT PLEASE HELP!!!!! || BRAINLEST WILL BE AWARDED AND ILL ANWSER YOUR QUESTIONS ]
Answer:
option 3)
14% approx
Step-by-step explanation:
Given data
Initial= $18.00
final =$20.50
% increase= final - initial/initia *100
% increase= 20.50-18.0/18*100
% increase=2.5/18*100
% increase=0.138*100
% increase=13.8%
Hence the increase is 13.8%
=14% approx

if 20% of a number is 386, what will be 30% of the same number
if the 20% of a number is 386, what will be 30% of the same number
Answer will be 157
If 20% of a number is 386, 30% of the same number is 579
How to determne the number?Let the number be x.
So,we have:
20% * x = 386
Express 20% as 0.20
0.20 * x = 386
Divide both sides by 0.20
x = 1930
30% of the number is represented as:
30% * 1930
Evaluate the product
30% * 1930 = 579
Hence, 30% of the same number is 579

Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180
90 + 50 +10x = 180 {Combine like terms}
140 + 10x = 180 {Subtract 140 from both sides}
10x = 180 - 140
10x = 40 {Divide both sides by 10}
x = 40/10
x = 4
