At school, 588 students bought a school

Mathematics
1 answer:
Reptile [31]3 years ago
6 0

Answer:

80%

Step-by-step explanation:

Step 1: Add the given data

588 + 147 = 735

Step 2: Divide the number of students who bought a school shirt by the total number of students

588 ÷ 735

= \frac{735}{588}

= 0.8

Step 3: Convert the decimal to fraction

0.8 = 80% (Move the zero 1 place behind the number and remove the ".")

Or

0.8 × 100 = 80%

Therefore, 80% of students bought a school shirt.

Dahasolnce [82]
Let the height of the rocket be x, then
tan theta = h / 1 mile
h = 1 tan theta miles

But 1 mile = 5280 feets

Therefore, the height in feet = 5280 tan theta.

Can you help me please
user100 [1]

The answer to this question is 10. The working out is shown in the image attached.

*** Sorry instead of writing 170 I wrote 270 for the big angle.. other than that it's correct

or another way to solve this is....

we know that a straight line is 180 degrees and the angle APD is 170 all we need to do is subtract 170 from 180 to get the answer of DPB

Hope this helped

Two side lengths of a triangle are given as 9 cm and 5 cm. What could be the length of its third side? 3cm
disa [49]

The length of the third side could be 5 cm ⇒ 3rd answer

Step-by-step explanation:

There is a fact in any triangle, that the sum of the lengths of the

smallest two sides of a triangle must be greater then the length of

the largest side

The sum of smallest 2 sides > the 3rd side

So to solve the problem

1. Chose the third side from the answer

2. Add the lengths of the two smallest side

3. Compare between the sum and the 3rd side

∵ The length of the two sides of a triangle are 9 cm and 5 cm

- If the third side is 3 cm

∵ 3 and 5 are the smallest side

∵ 3 + 5 = 8

∵ 8 < 9

∴ The sum of the smallest two sides < the 3rd side

∴ 3 cm can not be the length of the 3rd side

- If the third side is 4 cm

∵ 4 and 5 are the smallest side

∵ 4 + 5 = 9

∵ 9 = 9

∴ The sum of the smallest two sides = the 3rd side

∴ 4 cm can not be the length of the 3rd side

- If the third side is 5 cm

∵ 5 and 5 are the smallest side

∵ 5 + 5 = 10

∵ 10 > 9

∴ The sum of the smallest two sides > the 3rd side

∴ 5 cm can be the length of the 3rd side

- If the third side is 14 cm

∵ 5 and 9 are the smallest side

∵ 5 + 9 = 14

∵ 14 = 14

∴ The sum of the smallest two sides = the 3rd side

∴ 14 cm can not be the length of the 3rd side

The length of the third side could be 5 cm
