Using the approximation 3.14 for pi, what is the radius of a circle with circumference 69.1 m?
Answer:
11.0
Step-by-step explanation:
Circumfrence = 2 x pi x r.
making radius, r the subject of relation, you.get 11.003184713
Answer:
Hey!
Your answer is 11cm!
Step-by-step explanation:
So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14
Radius = [tex]\frac{C}{2\pi }[/tex] ... (that's the formula)
WE SUBSTITUTE IN:
Radius = 69.1/2 x 3.14
69.1/6.28
This equals = 10.99760656765
BUT 11cm when you round it to the next whole number or 2sf

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
Given;
Gianna walked 12 miles in 6 hours
6hours= 12 miles
1hour= 12/6miles
1hour= 2miles
Therefore, the rate of gianna by unitary will be 2mph

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −190 feet. Then she continued to hike down for another 20 minutes at a different rate. Her change in elevation for this part of the hike was −200 feet. During which portion of the hike was her rate of change in elevation greater? Complete the explanation. Her rate was faster in the (Select: First, Second) part of the hike, because her heart rate was ____ ft/min in the first part and ___ ft/min in the second part.
Answer:
Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part
Step-by-step explanation:
Portion 1
Time taken to hike down = 10 minutes
Change in elevation = - 190 ft
Portion 2
Hiked down for further 20 minutes
Change in elevation = - 200ft
During which portion of the hike was her rate of change in elevation greater?
Rate of change in elevation :
Change in elevation / time
Portion 1:
Rate of change in elevation :
Change in elevation / time
- 190 ft / 10 minutes = - 19 ft/minutes
Portion 2:
Rate of change in elevation :
Change in elevation / time
- 200 ft / 20 minutes = - 10 ft/minutes
Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part
Jacinda made 16 baskets during the basketball game. Greta made 4 baskets. The number of baskets Jacinda made is how many times more than the number of baskets Greta made? Choose the answer that has the correct equation AND the correct solution to the equation.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Jacinda = 16 baskets
Greta = 4 baskets
The number of baskets Jacinda made is how many times more than the number of baskets Greta made?
To obtain this :
Number of baskets Jacinda made / Number of baskets Greta made
If Jacinda's basket = J ; Greta's basket = G
J / G
16 / 4 = 4
Hence, Number of basket Jacinda made is 4 times more than that made by Greta

Which one and don’t lie!!
Answer:
I am 99.99% sure its D.
Step-by-step explanation:
That red line is on the negative side of the x-axis and since all the numbers are 7 I'm just gonna assume that its a negative 7. Good luck sugar plum ;)
Answer: Not lying cause what's the point of lying to someone asking for help. The answer is x = -7
Step-by-step explanation: X= -7 because if you look at a graph with negative and positive on it along with the Y and the X on it. Then you'll see that the middle of the plus is zero the left of the middle (going down the X axis) is negative. And the right side of the X axis is positive and the line is on the negative side of the X axis. That's why instead of it being Y= -7 ( which is NOT the answer) is wrong because the line is over the X axis instead of the Y axis.

2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?
Answer:
He can buy 5
Step-by-step explanation:
To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.
Hope this helps :)
Step-by-step explanation:
One action figure can be shown as x so x=$3.50.
Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.
20÷3.50 =5 2.5/3.5
So x=5 2.5/3.5
