ANSWER FAST ITS URGENT

Vlad1618 [11]

Answer:

9) 6.3 units

11) n=6√2 and m=12,

10) m=6√3, n=6

12) 330.6 ft

Step-by-step explanation:

1) The Pythagoras Theorem says that, the square of the hypotenuse is the sum of the squares of the two shorter legs.

Let the missing side, which is the hypotenuse be x.

Then

${x}^{2} = {2}^{2} + {6}^{2}$

${x}^{2} = 4 + 36$

${x}^{2} = 40$

$x = \sqrt{40}$

$x = 6.3$

The missing side is 6.3 units to the nearest tenth.

2) This is an isosceles right triangle.

This implies that, the two legs are equal.

$n = 6 \sqrt{2}$

The hypotenuse can be found using Pythagoras Theorem.

${m}^{2} = {(6 \sqrt{2} )}^{2} + {(6 \sqrt{2} )}^{2}$

${m}^{2} = 36(4)$

$m = \sqrt{36 \times 4} = 6 \times 2 = 12$

3) The side lengths of 30°-60°-90° are in the ratio, 2x,x√3,x

From the diagram, the hypotenuse is 12, therefore the other two legs are

$n = \frac{1}{2} (12) = 6$

and

$m = 6 \sqrt{3}$

4) The height of the monument is 115 feet, the hypotenuse is 350.

By Pythagoras Theorem,

${x}^{2} + {115}^{2} = {350}^{2}$

${x}^{2} = {350}^{2} - {115}^{2}$

${x}^{2} = 109275$

$x = \sqrt{109275} = 330.6 ft$

Calculate the length of BE

lora16 [44]

Answer:

BE = 72 cm

Step-by-step explanation:

$\frac{AB}{BC} = \frac{BE}{CD}$ (BPT Theorem)

$\frac{20}{5} = \frac{BE}{18} \\$

⇒ 4 = $\frac{BE}{18}$

⇒BE = 18 × 4

∴ BE = 72 cm

All the numbers that round to 940,000 when rounded to the nearest ten thousand?

timurjin [86]

The required number is 940,000.

It is required to find the solution.

<h3>What is rounded number?</h3>

A number that is easily multiplied, divided, etc., and especially a number that ends in zero.

Solution:

To round a number to the nearest 10,000, check the thousands digit to decide whether to round up or round down. If the thousands are 5000 or more, round up. If they are 4999 or less, round down. 45,000 to the nearest 10,000 is 50,000.

The numbers that round to 940,000 when rounded to the nearest ten thousand is 940,000.

Therefore, the required number is 940,000.
