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.

Answer:
C
Step-by-step explanation:
The guy who has 7.5k answers said so. Plus I need the 50 B Points
The equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200
What is an equation?Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.
Given that, a graph that shows the harvest results of a farm, we need to construct an equation that will give a relation between the compost used and the yield,
So the coordinates are
(0,200)
(200,400)
(400,600)
(600,800)
Finding the slope,
600-400 / 400-200 = 200/200 = 1
The y-intercept is 200, so, the relationship is
y=200+x
Hence, the equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200

In at least 100 words independently write your response to the statement, "Anyone can do well in math."
Answer:
I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.
Not 100 words, but should do trick if you just add in some extra words between phrases, and substitute some words with one or two synonyms.

On farmer Palmer’s farm, the cats have got into the chicken coop and are causing chaos.
Farmer Palmer counts in total, 11 heads and 30 legs. How many cats and how many chickens are in the chicken coop. Show a step by step method using simultaneous equations.
The number of chickens and goats will be 7 and 4, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
On farmer Palmer’s farm, the cats have got into the chicken coop and are causing chaos. Farmer Palmer counts in total, 11 heads and 30 legs.
We know that a goat has four legs and a chicken has 2 legs.
Let 'x' be the number of chickens and 'y' be the number of goats. Then the equations are given as,
x + y = 11 ...1
2x + 4y = 30 ...2
From equations 1 and 2, then we have
2(11 - y) + 4y = 30
22 - 2y + 4y = 30
2y = 8
y = 4
Then the value of 'x' is given as,
x = 11 - 4
x = 7
The number of chickens and goats will be 7 and 4, respectively.

Plz need help I will mark branliest
Answer:
see explanation
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 49 ← is in this form with
r² = 49 ( take square root of both sides )
r = [tex]\sqrt{49}[/tex] = 7
Thus A = (7, 0 ) and B = (0, 7 )
To find M use the midpoint formula
M = ( [tex]\frac{7+0}{2}[/tex], [tex]\frac{0+7}{2}[/tex] ) = (3.5, 3.5 )
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{x_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3.5, 3.5 )
m = [tex]\frac{3.5-0}{3.5-0}[/tex] = [tex]\frac{3.5}{3.5}[/tex] = 1
y = x ← equation of line passing through O and M
Answer:
Below in bold.
Step-by-step explanation:
(a)
At point A, y = 0 so the coordinates of A are found as follows:
x^2+ 0^2 = 49
x^2 = 49
x = 7 so A is (7, 0).
In a similar way, by putting x = 0 in the equation, we can show that
B = (0, 7).
(b)
M is the midpoint of the line AB so its coordinates are:
(7+ 0)/2, (0 + 7) /2 = (3.5, 3.5).
So the slope of OM which also passes through the origin (0,0) is:
(3.5 - 0) /(3.5 - 0) = 1.
y - y1 = m (x - x1)
y - 3.5 = 1(x - 3.5)
y = x - 3.5 + 3.5
y = x is the required equation.
Noah can't wait for lunchtime. Today is taco day! The cafeteria made three times as many beef tacos as chicken tacos and 50 more fish tacos as chicken tacos. They made 945 tacos in all. How many more beef tacos are there than fish tacos? Correct answer with units (if applicable) is worth 2 points; correct answer only is worth 1 point.
Answer:
308 beef tacos
Step-by-step explanation:
Let chicken tacos = c
Let beef tacos = 3c
Let fish tacos = c + 50
945 = c + 3c + c + 50
Simplify to 945 = 5c + 50
Subtract 50 on both sides and divide 5 to get
chicken tacos = 179
Plug in 179 to beef tacos to get 179*3 = 537
Plug in 179 to fish tacos to get 179 + 50 = 229
Subtract 537-229 to get how many more beef tacos than fish tacos, and so the answer is 308 beef tacos

Pam Everett earned gross wages of $378. Pam's deductions were: $28 in federal withholding taxes, 6.2% in Social Security taxes, 1.45% in Medicare taxes, $20.4 in health insurance, and $28 in union dues. Find the total deductions from Pam's gross pay.
Answer:
Total deductions = $105.317
Step-by-step explanation:
Gross earning = $378
Deductions:
Federal withholding tax = $28
Social security tax = 6.2% of $378 = $23.436
Medicare tax = 1.45% of $378 = $5.481
Health insurance = $28
Total deductions is gotten by summing up all values above
28+23.436+5.481+20.4+28
= $105.317
The difference between gross earning and deductions
= 378-105.317
= $272.683
