Jesse measured his height to be 67 inches. His actual height is 68.5 inches. What is the percent error for Jesse's measurem

Answers

Answer:

2.24%

Step-by-step explanation:

Given that :

Actual height = 68.5

Measured height = 67

Percentage error :

(Error value / True value) * 100%

Error = Actual - observed = (68.5 - 67) = 1.5

Percentage error :

(1.5 / 67) * 100%

0.0223880 * 100%

= 2.2388%

= 2.24%


The shapes of the horizontal cross-sections of the cone below are not all
congruent.
A. True
B. False

Answers

Answer:

B. False

Step-by-step explanation:

We are given the statement,

'The shapes of the horizontal cross-sections of the cone are all congruent'.

Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.

Further, the radius of the circle vary depending on the position form where the cone is cut i.e.

If cut from the top, the circle is approximately equal to a point.

If cut from the middle, the radius of the circle is less than the radius of the cone.

If cut from the bottom, the radius of the circle is equal to the radius of the cone.

Now, 'two figures are congruent if they overlap each other'.

Since, the circles have different radius, they will not overlap each other.

Thus, all the cross-sections of the cone would not be congruent.

Hence, the given statement is false.

Step-by-step explanation:

The solution is, the given statement is B. False.

What is a cross-section of any shape?

A cross-section is a shape formed by cutting a solid (such as a cone, cylinder, or sphere) with a plane. If a cylinder-shaped object is cut by a plane parallel to its base, the resulting cross-section is a circle. As a result, the object intersected.

here, we have,

We are given the statement,

'The shapes of the horizontal cross-sections of the cone are all congruent'.

Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.

Further, the radius of the circle vary depending on the position form where the cone is cut i.e.

If cut from the top, the circle is approximately equal to a point.

If cut from the middle, the radius of the circle is less than the radius of the cone.

If cut from the bottom, the radius of the circle is equal to the radius of the cone.

Now, 'two figures are congruent if they overlap each other'.

Since, the circles have different radius, they will not overlap each other.

Thus, all the cross-sections of the cone would not be congruent.

Hence, the given statement is false.

A cyclist travels at an average speed of 20 km/h over a distance of 40 km.
How many hours does it take him?

Answers

Answer:

Given that speed(v) = 20km/h and time(t) = 50 min

We have to find distance (d)

First convert speed into m/s

v = (20*1000m)/(1*3600s)

v = (50/9) m/s

Now convert time into second

t = 50*60 = 3000 sec

As we know that

d = v*t = (50/9)*3000 = 50000/3

d = 16666.67m or 16.67km

Ans: 16666.67m or 16.67km

Step-by-step explanation:

Answer is equal to
16.67gm
