The length of a garden is 23m, correct to the nearest metre.

Write down the least possible length of the garden.

Answers

Answer:

22.5m

Step-by-step explanation:

Since it's correct to the nearest metre, it has an interval of ± 0.5

Using rounding concepts, it is found that the least possible length of the garden is of 22.5m.

------------------

If the first decimal digit is between 0 and 4, rounding to the nearest integer, the integer part remains the same.If the first decimal digit is between 5 and 9, rounding to the nearest integer, one is added to the integer part.Thus, in the context of this problem, garden lengths between 22.5 and 23.4 are rounded to 23m, and thus, the least possible length of the garden is 22.5m.

A box contains 4 bags of sugar. the total mass of all 4 bags is 6 kg what is the mass of each bag in grams ​

Answers

Answer:

Divide by 4 to get the mass of a single bag and then multiply by 1000 to get to grams from kilograms

Step-by-step explanation:

6/4=1.5

1.5*1000=1500

So, in total a bag of sugar would cost 1500

It’s simple, really- the answer is 1500g or 1.5kg.

All you have to do is divide 4 by six to get the mass of each separate bag.

4/6= 1.5kg

Or 1500g

Two airplanes leave the airport at the same time. One plane is flying 700mph at a bearing of N46°W and the other plane is flying 895mph at a bearing of
N43° E. After 3 hours, how far are the planes from one another?

Answers

9514 1404 393

Answer:

  3380 miles

Step-by-step explanation:

The distance separating the planes can be found using the law of cosines. One plane has gone 3×700 = 2100 miles; the other has gone 3×895 = 2685 miles. The angle between their flight paths is 46°+43° = 89°. Then the separation (s) is ...

  s² = 2100² +2685² -2(2100)(2685)cos(89°) = 11,619,225 -11,277,000×0.01745

  s² ≈ 11,422,414.21

  s ≈ √11,422,414.21 ≈ 3379.7

The planes are separated by about 3380 miles after 3 hours.

2. The following triangle, ∆, has angle measures as shown.
Step 1: What is the measure of angle C? Show your work.
Step 2: What is the value of x? Show your work.

Answers

Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.  

Angle C= 93 degrees.

A and B are two similar shapes the area of shape A is 200cm2 calculate the area of shape B

Answers

Answer:

Area of shape B = 312.5 cm²

Step-by-step explanation:

Ratio of Area of A : Area of B = 12² : 15²

Given that area of A is 200 cm², let the area of shape B = x

Therefore:

200:x = 12²:15²

200/x = 144/225

Cross multiply

144x = 200*225

144x = 45,000

x = 45,000/144

x = 312.5 cm²

Area of shape B = 312.5 cm²
