Two joggers set out at the same time from their homes 21 miles apart. They agree to meet at a point somewhere in
between in an hour and a half. If the rate of one is 2 mph faster than the rate of the other, find the rate of each
The two joggers who are 21 miles apart travel at a speed 8 mph and 6 mph respectively and would meet after one and half hours.
What is an equation?An equation is an expression used to show the relationship between two or more variables and numbers.
Let a represent the speed of the faster jogger and represent the speed of the other jogger. Hence:
a = b + 2 (1)
Also:
In one and half hour (1.5 h):
a = d₁/1.5
d₁ = 1.5a
b = d₂/1.5
d₂ = 1.5b
d₁+ d₂ = 21
1.5a + 1.5b = 21 (2)
From both equation 1 and 2:
a = 8, b = 6
The speed of the joggers is 8 mph and 6 mph respectively.

What civilization found the first known value of pi?.
Answer: The Egyptians, Babylonians, and Archimedes.
Step-by-step explanation: The Egyptians and Babylonians were the first known civilizations to use pi. At the time, Egyptians devised the approximated value of pi as 3.1605. Archimedes, however, did the first calculation of pi, with its approximate value of 3.141592 or 3.14 to make it shorter.

Step-by-step explanation:
The roots of the quadratic equations or the values of x are -5 and 2/3.
What is a quadratic equation?A quadratic equation is an algebraic equation of degree two. An algebraic equation of degree n has exactly n number of roots.
Given a quadratic equation 3x² + 13x = 10 which can be written as,
3x² + 13x - 10 = 0.
Now two numbers that add to 13 and multiplied to -30 are 15 and - 2.
3x² + 15x - 2x - 10 = 0.
3x(x + 5) - 2(x + 5) = 0.
(x+5)(3x-2) = 0.
x + 5 = 0 OR 3x -2 = 0.
x = -5 OR x = 2/3.

The original price of a T-Shirt is $15. The T-Shirt is on sale for 35% off. What is the sale price?
Answer:
9.75$
Step-by-step explanation:
Answer:
9.75$
Step-by-step explanation:
The original price of the shirt is $15, and it's on sale for 35% off. What is the item's sale price?
First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.
Second, find out what 35% of $15 is. This is the amount of the sale discount. This is always found by multiplying 0.350 by the item's cost $15, like this:
0.350 x $15 = $ 5.25.
So for this sale, you'll save $ 5.25 on this item.
This means, the cost of the item to you is
$15 - $ 5.25 = $ 9.75.
Max wants to rent a bicycle. The cost to rent a bike is a $5 insurance fee plus $3 per hour. Max has at most $20 to spend. Write an inequality to represent this scenario. Give a value that satisfies the inequality.
Answer: 5 + 3x ≤ 20; 5
Step-by-step explanation:
at most means not more than(less or equal to),which use the symbol ≤. Let x be the hour that Max rent.
5 + 3x ≤ 20
3x ≤ 15 [Subtract 5 from both sides.]
x ≤ 5 [Divide 3 from both sides.]
Any value less than or equal to 5 will be satisfies the inequality.

what is the line of symmetry of the parabola y=x2+6×-9
x=6
x=-9
×=-3
Answer:
x = - 3
Step-by-step explanation:
given a parabola in standard form y = ax² + bx + c (a ≠ 0 )
then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 6x - 9 ← is in standard form
with a = 1, b = 6 , then the equation of the axis of symmetry is
x = - [tex]\frac{6}{2}[/tex] = - 3 , that is x = - 3

Tasha earns $75,000 per year. Her payroll deductions are 28% of her gross income. She saves 5% of her net
income each month in case of an emergency. How much will she budget for her emergency savings for the month
of March?
O $3,750
$312.50
O $87.50
O $225.00
Answer:
87.50
Step-by-step explanation:
75,000 x 28% ÷ 12
She will budget $225 for her emergency savings for the month of March
How to determine the amount saved for emergency?We have:
Gross = $75,000 per year.
Payroll deductions = 28%
So, the net pay is:
Net = (1 - 28%) * $75,000
Evaluate
Net = $54000
The net income per month is:
Monthly = $54000/12
Evaluate
Monthly = $4500
5% of her net income goes to emergency.
So, we have:
Emergency = 5% * $4500
Evaluate
Emergency = $225
Hence, she will budget $225 for her emergency savings for the month of March

What trigonometric expression can be used to find the value of X? Replace a and b with the correct values
Answer:
a=12 b=25 degrees
Step-by-step explanation:
the tangent of the 25 degree angle gets you your answer
Trigonometry ('triangle', or 'measure') is the branch of mathematics that studies relationships between side lengths or the angles of the triangles
by the question, we have the following parameters:
Vertical Leg = x
Base length = 12
Angle at the vertical side = 25 degrees
The measure of the x is then calculated using the following tangent ratio
tan(x) = Base length / Vertical leg
Substitute known values
tan(x) = 12/x
So, the trigonometric expression that it is be used for find the value of x is tan(x) = 12/x
