H (4.84) will be the correct answer

Answer: You are correct. The answer is choice (H) 4.84

======================================================

Explanation:

10% = 10/100 = 0.1

10% of 4.4 = 0.1*4.4 = 0.44

Increasing 4.4 by 10% means we add on 0.44 to get 4.4+0.44 = 4.84

So the ruler says 4.4 inches but the actual table could be as long as 4.84 inches.

---------

A shortcut is to compute it like this:

4.4*1.1 = 4.84

The multiplier 1.1 represents an increase of 10% because

1.1 = 1 + 0.1 = 100% + 10%

This shortcut allows for multiple percentage increases that can be chained together fairly quickly.

Steam boat (b) = speed of 36.8km/h. In 1.75 hours out same port and going same direction departed speed boat (s). In 1.8 hours later distance between the speed boat (s) and steam boat (b) was 86.9km

Scenario A) the steam boat (b) stays ahead of the speed boat (s)
-----------------------------------
Start by first finding the total distance (d) that the steam boat (b) traveled. That would be 1.75+1.8 = 3.55 hrs
distance (d) = rate (r) × time (t)
d(s) = rt = (36.8km/h)(3.55h) = 130.64 km
Secondly, let's subtract from d the distance between b and speed boat (s):
d(s) = 130.64 - 86.9km = 43.74 km
Thirdly, since s traveled 43.74 km and left 1.8 hrs ago, let's set-up the rate of b [r(b)] equal to that distance [d(s)] divided by the time 1.8 hrs.
**Since d = rt, r = d/t
r(s) = d(s)/t = 43.74km/1.8h = 24.3km/h

Scenario B) the speed boat (s) moves ahead of the steam boat (b), this is more likely!!
-------------------------------------
b moves before s starts for 1.75 hrs, going 36.8km/h, that distance ahead + distance it travels after the next 1.8 hrs = 130.64 km
Now s starts and travels d(s) km at r(s) km/h
If s speeds past b in 1.8 hrs, and is AHEAD by the given distance of 86.9km, then total distance of s [d(s)] = the 130.64 b traveled PLUS the 86.9 it is now ahead
d(s) = 130.64+86.9 = 217.54 km
s still only traveled that in 1.8 hrs, so the speed/rate of s is:
r(s) = d(s)/t = 217.54km/1.8h = 120.86km/h

** I think that makes more sense, that a speed boat would move MUCH faster than a steam boat, if 120.9... than over 3 times faster!!

Hello :)

The question is asking about true statements, so let's go through the choices.

A) The profit increased for all five months; this question means that the profit (money value) should have increased every month; while it does from June to September, October goes down so this statement is false.

B) This statement is saying June + 100,000 dollars+ =August. June's profit is approximately 150,000 lower than August so this is true.

C) This answer choice explains October's profit was less than June's; 298,000 from October is bigger than 248,000 from June so this is false.

D) I can't read off the last statement but no profit is drastically bigger than the other for it to be twice as much of September.

Draw a circle with center A and a radius of your choice. Create three well-spaced points, B, C, and D, on the circle in clockwis

Dmitry [639]

Answer:

Please find attached the required circle

It is observed that the angle subtended by the arc CB which are m∠CAB and m∠CDB is such that the angle arc CB subtends at the center, m∠CAB is two times the angle that the arc CB subtends at the circumference

The measured angle subtended by the arc CB at the center m∠CAB = 64° and the measured angle subtended by the arc CB at the circumference m∠CDB = 32°

A solid cuboid is made from centimeter cubes how many centimeter cubes were used to make the cuboid

prisoha [69]

This question is incomplete because it lacks the appropriate diagram.

Please find attached this answer the appropriate diagram.

Kindly note that: The diagram was obtained from or referenced from Planes and Elevation (F) Version 3 January 2016.

Answer:

72 centimeter cubes

Step-by-step explanation:

Looking at the attached diagram, we are given 3 views of the cuboid

a) The plan view: The is the view of the cuboid from the top or a very high position

b) Front Elevation view: This is the view of the cuboid from the front

c) Side elevation view: This is the view of the cuboid from the side.

In the referenced and attached diagram,

The plan view shows us the top of the cuboid with a length of 4 and breadth of 6

The front elevation view shows us the front of the cuboid with a length of 3 and breadth of 4

The side elevation view shows us the side of the cuboid with a length is 3 and breadth of 6

We are told to find the number of centimeter cubes were used to make the cuboid. This means we are to find the volume of the cuboid.

Volume of a cuboid = Length × Width × Height

Combining the 3 views together,

The Length of the cuboid = 4

Width of the cuboid = 6

Height of the cuboid = 3

Volume of the cuboid = 4 × 6 × 3

= 72

Therefore, the number of centimeter cubes that were used to make the cuboid is 72.
