In this problem, I would say 7.16 to the nearest 10th would be 7.20 because 16 is closer to 20 then 10.
Answer:
Option B. y = 2x; 20 feet
Step-by-step explanation:
1. Determination of the equation that represents the relationship.
Let y be the distance travelled.
Let x be the time taken.
Let K be the speed.
From the question given above, the following data were obtained:
Distance (y) = 80 ft
Time (x) = 40 s
Speed (k) =.?
Speed = Distance /time
K = y/x ......... (1)
K = 80/40
K = 2 ft/s
Substitute the value of k into equation 1
K = y/x
K = 2 ft/s
2 = y/x
Cross multiply
y = 2x
Therefore, the equation that represents the relationship is y = 2x
2. Determination of the distance travelled in 10 s.
Speed (k) = 2 ft/s
Time (x) = 10 s
Distance (y) =.?
y = 2x
y = 2 × 10
y = 20 ft
Therefore, the person will travel 20 feet in 10 seconds.
From the above calculations, the right answer to the question is
Option B. y = 2x; 20 feet
Answer:
✓✓ Area of traingle = 1.2 cm^2 ✓✓
Step-by-step explanation:
Hello mate (◕ᴗ◕✿)
=>> In above traingle, <u>height and hypotenuse are </u><u>given</u>
<u>=</u><u>></u><u> </u><u>height</u><u> </u>= 12 cm
<u>=</u><u>></u><u> </u><u>Hypotenuse</u> = 14 cm
✓✓ <u>Area</u><u> of</u><u> </u><u>traingle </u><u>=</u><u> </u><u>1</u><u>/</u><u>2</u><u>(</u><u>base*</u><u>height</u><u>)</u><u> </u><u>✓</u><u>✓</u>
<u> </u>we need to find base of above traingle
<u>Base </u><u>=</u><u> </u><u>√</u><u>H</u><u>y</u><u>p</u><u>o</u><u>t</u><u>e</u><u>n</u><u>u</u><u>s</u><u> </u><u>-</u><u> </u><u>√</u><u>P</u><u>e</u><u>r</u><u>p</u><u>i</u><u>n</u><u>d</u><u>i</u><u>c</u><u>u</u><u>l</u><u>a</u><u>r</u><u> </u>
Base = √14 - √12
Base = 3.7 - 3.4
Base = 0.2 cm
Now, we can find area of traingle
<u>Area</u><u> of</u><u> traingle</u><u> </u><u>=</u><u> </u><u>1</u><u>/</u><u>2</u><u>(</u><u>Base*</u><u>Height</u><u>)</u>
<u> </u><u> </u><u> </u><u>Area</u><u> of</u><u> traingle</u><u> </u><u>=</u><u> </u><u>1</u><u>/</u><u>2</u><u>(</u><u>0</u><u>.</u><u>2</u><u>*</u><u>1</u><u>2</u><u>)</u>
<u> </u><u> </u><u> </u><u>Area</u><u> of</u><u> traingle</u><u> </u><u>=</u><u> </u><u>6</u><u>*</u><u>0</u><u>.</u><u>2</u>
<u> </u><u> </u><u> </u><u> </u><u>Area</u><u> of</u><u> traingle</u><u> </u><u>=</u><u> </u><u>1</u><u>.</u><u>2</u><u> </u><u>cm^</u><u>2</u>

Answer:
false
Step-by-step explanation:
The horizontal axis is the x axis.
I don't really know what your school wants in the blank but here's what I think it is:
The horizontal axis on the coordinate grid is the x axis.
Hope this helps! let me know if its right!
