Mary walks to her garage. The distance to the garage as a function of time is shown in this graph
A. Mary starts 8 meters from the garage.
B. Mary walks 8 meters every 4 seconds.
C. Mary arrives at the garage after 4 seconds.
D. Mary walks at a speed of 2 meters per second.
Answers
Answer:
d
Step-by-step explanation:
so if you look at the bottom left corner you can see 1 box is the same as saying for every second someone walks its one metre.
thats not how i got the answer though.
if you look at the starting point at 8 because she was 8 meters away you need to see when she comes across her first second which after 2 meters (Goes down two squares before reaching the first second)
now technically soe of the other answers are correct too but heres how i thought about it.
A. its correct but i dont think that's what its asking you for tbh
B. This we don't know for sure. eg she could take 890 seconds walking back to her starting point we just don't know for sure.
C. This is also true but once again it's easily given to you so i dont think that's what you're being asked.
D. This is the only option where you had to do any for of working out because s=d/t so s=8/4=2m/s

Answers
There are 30 geese.
STEP-BY-STEP EXPLANATION:
Let y be the total no. of animals
Share= ratio/total ratio X total
50= 5/8 X y
50= 5y/8
50 X 8= 5y
y= 400/5
y= 80
The total no. of animals is 80

Answer: C. 125.66 in²
Step-by-step explanation:
This is asking us to find the surface area of this cone. We can use the formula and solve.
A = πrl + πr²
A = π(4)(6) + π(4)²
A = π(4)(6) + π(4)²
A ≈ 125.66 in²
It would take C. 125.66 in² of toilet paper to cover the surface of this cone.

You are also given a 4 sided figure.
All 4 sided figures have 360 degrees
A radius meets a tangent at 90 degrees
Formula

Solution
90 + 90 +40 + <BDC = 360 Combine
220 + <BDC = 360 Subtract 220 from both sides

4. The base rate for workers' compensation insurance for roolers
in one state is $16.95 per $100 paid to employees. The total
monthly payroll for Certified Roofing is $15,738.00. What is the
monthly premium for workers' compensation insurance?
Answers
Answer:
$2,667.59
Step-by-step explanation:
The insurance premium is found by multiplying the payroll amount by the premium rate.
($15,738) × $16.95/$100 = $15,738 × 0.1695 ≈ $2,667.59
The monthly workers' compensation insurance premium is $2,667.59.

What is the constant term in the expression 8xy − 9x2 y − 5x 6
Answers
Answer:
6
Step-by-step explanation:
A constant is a term without a variable.
Every other number has a variable (x,y) to it except for 6.
Feel free to save this for whenever you get stuck on things like this! I know this section is hard.
In the expression 8xy − 9x^2+ y − 5x +6 the constant term is 6 which is a fixed quantity or cannot be changed.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have an expression:
[tex]\rm 8xy-9x^2+y-5x+6[/tex]
Let's denote it with f(x,y)
[tex]\rm f(x,y) =8xy-9x^2+y-5x+6[/tex]
As we know the constant term means which cannot be changed that values are fixed or fixed quantity.
From the above expression, the constant value in the expression is 6
Thus, in the expression 8xy − 9x^2+ y − 5x +6 the constant term is 6 which is a fixed quantity or cannot be changed.

If you know the diameter of a circle,
how do you find the following. Explain
the steps clearly
a. the area of that circle?
b. the circumference of the circle?
Answers
Step-by-step explanation:
a. Area of a circle = πr², where r means radius.
Step 1: converted diameter to radius.
diameter = 2 radius
In other way of writing, radius = [tex]\frac{1}{2}[/tex] diameter.
Step 2: substitute radius into the formula.
Area of a circle = π([tex]\frac{1}{2}[/tex]d)²
Step 3: substitute π into the formula.
some question is given the value of π), if not substitute 3.14 for π.
Area of a circle = 3.14([tex]\frac{1}{2}[/tex]d)²
Step 4: substitute d into the formula, then we can solve its area.
b. a. Circumference of a circle = 2πr, where r means radius.
Step 1: converted diameter to radius.
diameter = 2 radius
In other way of writing, radius = [tex]\frac{1}{2}[/tex] diameter.
Step 2: substitute radius into the formula.
C = 2π([tex]\frac{1}{2}[/tex]d)
Step 3: substitute π into the formula.
some question is given the value of π), if not substitute 3.14 for π.
C = 2(3.14)([tex]\frac{1}{2}[/tex]d)
Step 4: substitute d into the formula, then we can solve its circumference.
