Answer:
Minor note: A table is circular.In this case, the area is more useful to find out how much the paint covers.
This is, because the circumference is the perimeter of the table whilst the area is the whole region of the table.
So to find out the area of this table, we must use the formula for the area of a regular circle.
A = π[tex]r^{2}[/tex]
Where 'π' represents pi(22/7 or 3.14), and 'r' represents the radius which is being squared.
But, if we see the information that we have, we can see that it gives the diameter and not the radius.
So in order to find out our radius, we must perform 1/2 of the diameter(1/2 x diameter) to find the radi.
30(diameter) x 1/2
= 15 is the radius.
Now we substitute this value into our equation, since it's the only information we need.
A = π[tex]r^{2}[/tex]
A = 3.14(15^2)
A = 3.14(225)
A = 706.5 square inches of paint is needed to cover the table.

We have x = 81 repeat itself. Any time x repeats, it means we don't have a function.
Put another way, the input x = 81 leads to more than one y output. A function is only possible if any given input leads to exactly one output. The input must be in the domain.

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

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

Answer:

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.
Given the relation R = {(−2, 3), (b, 4), (1, 9), (0, 7)}, what value for b would make this relation NOT a function.

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.

Step-by-step explanation:
you can divide part of a whole by the whole to get a decimal
this decimal is the percentage when you move the decimal 2 places to the right
32 - 9 = 23 men
23/32 = .72 (rounded)
.72 = 72%
Find te slope of the graph
Answer:
It is d. 3/2
Step-by-step explanation:
slope formula is rise over run or x2-x1/y2-y1. So it would be 6-0/4-0. That equals 6/4. You just need to simplify that by dividing both 6 and 4 by 2 and you get 3/2.
