Answer:

$D = 7\sqrt 2$

Step-by-step explanation:

Given

$A = (-3,-4)$

$B = (4,3)$

Required

The distance between them

This is calculated as:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

So, we have:

$D = \sqrt{(3-(-4))^2+(4-(-3))^2}$

$D = \sqrt{7^2+7^2}$

$D = \sqrt{2(7^2)}$

$D = 7\sqrt 2$

So to find the area you should draw a line to make a right triangle then take the area of the 3 figures and add them together. See the picture.

An empty box is shaped like a rectangular prism. The box has a base area of 9/10 square foot and a height of 1/3 foot. How much

Ymorist [56]

Since we already know the base area, we simply have to multiply it by the height to get the volume of the box (how much packing material it can contain)

9/10 x 1/3

9 x 1 = 3
10 3 10 (I cancelled the 9 and 3 and made them 3 and 1 respectively)
The answer is 3/10 ft³

What is the length of BD ?

timama [110]

Answer:

ED = 6

Step-by-step explanation:

Use Pythagorean theorem to find the length of BE

100-64=x^2

x=6

because triangle BEA, and triangle DEA are congruent, the measure of BE, and DE are the same because of CPCTC

BE=DE=6

% error = {|Approximate Value - Exact Value| ÷ |Exact Value|} * 100%

The difference of the Approximate and the Exact Value is an absolute value. Therefore, the negative sign of the difference is disregarded.

1) Estimate = 250 g ; Actual = 240 g
(250 - 240)/240 * 100% = 10/240 * 100% = 4.17%

2) Estimate = 97.5°C ; Actual = 100°C
(97.5 - 100)/100 * 100% = |-2.5|/100 * 100/% = 2.5%

3) Estimate = 10.4 ml ; Actual = 9.7 ml
(10.4 - 9.7)/9.7 * 100% = 0.7/9.7 * 100% = 7.22%

4) Estimate = 0.156 cal/g°C ; Actual = 0.185 cal/g°C
(0.156-0.185)/0.185 * 100% = |-0.029|/0.185 * 100% = 15.68%

5) Estimate = 62.5 g ; Actual = 65.2 g
(62.50 - 65.20)/65.20 * 100% = |-2.7|/65.20 * 100% = 4.14%
