1. They will meet as 7:20 PM
explanation: The first friend runs at a speed of 8 miles per hour.
The second friend runs at a speed of 7 miles per hour.
they left at 6 p.m.
their houses are 20 miles apart,
Since they are running towards each other the effective speed will be
(8+7) = 15 mph
Distance = 20 miles
time they run = 20/15 =4/3 hours
They will meet at 7:20 pm

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the other leg measure 8cm? Please help with explanation. I'll mark you as brainiest.
Answer:
11.5 cm
Step-by-step explanation:
The dimensions of a right angled triangle can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + 8² = 14²
a² + 64 = 196
a² = 196 - 64
a² = 132
find the square root of 132
a = 11.5 cm

A rectangle has a length that is 4 times the width, w. If the perimeter of the rectangle has a perimeter of 40
feet, what is the length of the rectangle?
Answer: 16cm
Step-by-step explanation:
l = 4w
2l + 2w = p
2(4w) + 2w = 40
8w + 2w = 40
10w = 40
w = 4 cm
l = 4w = 4(4) = 16cm

Answer:
.71
Step-by-step explanation:
Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn
The question is incomplete. The complete question is :
Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?
Cost of lawn mower = $ 200
Cost of gasoline = $ 2 per lawn
Solution :
Given :
Cost of the lawn mower = $ 200
The cost of gasoline expense for one lawn = $ 2
The revenue generated for one lawn = $ 25
So let the number of lawn to be mowed = x
Therefore the total expenses = [tex]$200+2x$[/tex]
So, the total revenue = [tex]$25x$[/tex]
The point for which the revenue will exceed the total expenditure will be :
[tex]$25x \geq 200+2x$[/tex]
So at [tex]x=9, \ 225 > 218[/tex]
Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.
Answer:
For part a and b of this question
Step-by-step explanation:
x= # of lawns cut y= total cost
revenue: y=25x
cost: y= -2x-200
He earns 25 per lawn, but loses $200 for his lawnmower and $2 per lawn.
b. y=25x y=-2x-200 y=25x
y=-2x-200 25x=-2x-200 y=25(-7.40)
27x= -200 y=-185
x=-7.40
I believe this is correct.
Find the gradient of the line segment between the points (-4,-5) and (2,-4).
Answer:
1/6
Step-by-step explanation:
The gradient of the line segment is the same as slope
m = (y2-y1)/(x2-x1)
= ( -4 - -5)/( 2 - -4)
= (-4+5)/( 2 +4)
1/6
Answer:
Step-by-step explanation:
Gradient = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]=\frac{-4-[-5]}{2-[-4]}\\\\=\frac{-4+5}{2+4}\\\\=\frac{1}{6}[/tex]

A worker has 25 feet of ribbon to make bows. Each bow uses 2 feet of ribbon. The worker divides 25 by 2 and gets 12.5 as an answer.
What does the worker's answer mean in this context?
A. The worker can make 12 bows and have 1 foot of ribbon left.
B. The worker can make 12 bows and have 5 feet of ribbon left.
C. The worker can make 5 bows and have 12 feet of ribbon left
D. The worker can make 1 bow and have 12 feet of ribbon left.
Answer: The answer is because 12 is how many bows the work made and 0.5 is 5 feet of the ribbon left.

Calculate the discriminant of the quadratic equation.
Please I really need your help
Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
I need help on 7 and 8!!!!!Find the diameter of each circle. Use a calculator’s value of Pi. Round your answer to the nearest tenth.
Answer:
37.6 in
48.2 yd
Step-by-step explanation:
The are of a circle is given as :
Area = pi(d²) /4
Area = 1110.4in²
1110.4 = 3. 14 * d² / 4
1110.4 * 4 = 3.14 * d²
4441.6 = 3.14d²
d² = 4441.6 /3.14
d² = 1413.8051
d = 37.600
d = 37.6
8.)
Area, A = 1824.7yd²
1824.7 = 3. 14 * d² / 4
1824.7 * 4 = 3.14d²
7298.8 = 3.14d²
d² = 7298.8 / 3.14
d² = 2323.2801
d = sqrt(2323.2801)
d = 48.200
Hence, diameter = 48.2 yd

4. Halla el valor de x. *

x + 15x + 24 = -21 - 4x
Answer:
x= -9/4
Step-by-step explanation:
1) Isolate X
2) This will give you x+15x+4x=-21-24
(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)
3) Add the like terms
x+15x+4x = 20x
-21-24= -45
this will give you 20x=-45
4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)
x= -45/20
5) Simplify your answer
= -9/4
