The position of a diving bell is −3/4 mile relative to sea level. The diving bell reached this position after dropping from sea

level at a constant rate for 1 1/2 hours. What was the position of the diving bell relative to sea level 1 hour after it began its descent? Enter your answer in the box.

<span>After 1 hour, the diving bell was -1/2 mile relative to sea level. Since the rate of decent is constant, we can use two ratios to represent the depth at 2 different times. To make things easier to write, I'll use decimals to represent time and depth. -.75 / 1.5 = x / 1 Now solve for x -0.5 = x So after 1 hour, the diving bell was -1/2 mile relative to sea level.</span>

The ratio of width to length of a rectangle is 7:10.The width of the rectangle is 91 cm.
kvasek [131]

Answer:

Length= 130 cm

For, Width= 91 cm

Step-by-step explanation:

Ratio of the width to the length of the rectangle = 7:10

Width of the rectangle= 91 cm

\frac{Width}{Length} =\frac{7}{10}

As, Width = 91 cm

\frac{91}{Length} =\frac{7}{10}

On, Cross multiplication the fraction:

91*10=7*Length

7*Length=910

Dividing by '7' both the sides:

Length=\frac{910}{7}\\\\ Length=130cm

WILL GIVE BRAINLIST SOON AS I CAN SOMEBODY PLEASE HELP ME ​
fgiga [73]

Answer:

A= 75.06 Sq Cm

Step-by-step explanation:

Please refer to the picture attached with this.

In ΔABD

AB = 8.5 , AD = 6 and say BD = x

Applying Pythagoras theorem in this triangle

Pythagoras theorem says

a^2+b^2=c^{2}

where c is the side opposite to the right angle, and b and a are the other two sides of the right angled triangle.

x^2+6^2=8.5^{2}

x^2=72.25-36

x^2=36.25

x=6.02

Hence side a = x +19

a = 6.02+19

a = 25.02

Now we apply the formula for area of a triangle which is given as

A=\frac{1}{2}\times b \times h

Where b is the base , here we have base as a = 25.02

h is the height , here h = 6

Putting these values in Formula we get

A=\frac{1}{2}\times 25.02 \times 6

A= 25.02 \times 3

A=75.06

Hence Area of the triangle is 75.06 sq cm
