What is the length of the hypotenuse?

Charra [1.4K]

Answer:

Hello! answer: 85

Step-by-step explanation:

68 × 68 = 4624

51 × 51 = 2601

4624 + 2601 = 7225

√7225 = 85

85 × 85 = 7225 therefore c = 85 Hope that helps!

A city in the Pacific Northwest recorded its highest temperature at 91 degrees F and its lowest temperature at 12 degrees F for

docker41 [41]

Answer:

(A)12-19

Step-by-step explanation:

To construct a frequency distribution, we follow the steps below.

1. Find the largest and smallest values.

91 and 12 respectively

Compute the Range = Maximum - Minimum=91-12=79

2. Determine the number of classes desired.

In this case, we desire 10 classes

3. Next, we find the class width by dividing the range by the number of classes and rounding up.

79÷10 = 7.9

Rounded Up, Class Width=8

4. Pick a suitable starting point less than or equal to the minimum value.

Since our minimum value is 12, we pick a class starting with 12 and give a class width of 8.

Therefore the upper and lower limits of the first class is given as:

12-19.

Which of the following is a point slope equation of a line that passed through the points (10,5) and (4-7)

levacccp [35]

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (10, 5) and (4, -7). Substitute:

$m=\dfrac{-7-5}{4-10}=\dfrac{-12}{-6}=2$

$y-5=2(x-10)$

Compute the following volume and surface area.

Vesnalui [34]

The surface area of rectangular solid is 208 square centimeter

The volume of rectangular solid is 192 cubic centimeter

<h3><u>Solution:</u></h3>

Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm

To find: surface area and volume of rectangular solid

Length = l = 4 cm

Width = w = 6 cm

Height = h = 8 cm

<h3><em><u>The formula to find the surface area of a rectangular prism is:</u></em></h3>

Surface Area = 2wl + 2lh + 2hw

where w is the width, the l is the length, and the h is the height.

$\text {surface area }=2(4 \times 6)+2(4 \times 8)+2(8 \times 6)\\\\\text {surface area } = 2(24) + 2(32) + 2(48)\\\\\text {surface area } = 48 + 64 + 96 = 208$

Thus the surface area of rectangular solid is 208 square centimeter

<h3><em><u>The formula for volume of rectangular solid is:</u></em></h3>

$Volume = Length \times Height \times Width$

$volume = 4 \times 6 \times 8 = 24 \times 8 = 192$

Thus the volume of rectangular solid is 192 cubic centimeter
