find the area of a parallelogram if a base and corresponding altitude have the indicated lengths base 1 1/2 feet , altitude 6 in
Ostrovityanka [42]

The area of parallelogram is 108 square inches

<em><u>Solution:</u></em>

<em><u>The formula for area of parallelogram is:</u></em>

Area = base \times height

From given,

Base = 1\frac{1}{2}\ feet = \frac{2 \times 1 + 1}{2} = \frac{3}{2}\ feet

Height = 6\ inches

<em><u>Convert feet to inches</u></em>

1 feet = 12 inches

\frac{3}{2}\ feet = \frac{3}{2} \times 12\ inches = 18\ inches

<em><u>Therefore, area of parallelogram is:</u></em>

Area = 18 \times 6\\\\Area = 108

Thus area of parallelogram is 108 square inches

Using the ruler postulate, find the distance between –9 and 2.
gulaghasi [49]

Answer:

11 units

Step-by-step explanation:

According to ruler postulate, if there are two points A with coordinate a

and point B with coordinate b, \

then distance ab is given by subtracting coordinate in any order i.e it can be (a-b) or (b-a) and then take the absolute value value of it.

mathematically it can be represented as

AB = |a-b| or |b-a|

_________________________________________

in the given problem points are -9 and 2

thus distance

distance between –9 and 2  = |-9 -2| = |-11|  = 11

absolute value of -11 is 11

alternatively, distance can be calculated as

distance between –9 and 2  = |2 -(-9) | = |2 + 9 | = |-11|  = 11

HELPP PLEASE ASAP Use the Pythagorean theorem to find the missing length in the right triangle
qwelly [4]

Answer:

c = 10

Step-by-step explanation:

The pythagoras theorem :

a² + b² = c²

a = 6 and b = 8

6² + 8² = c²

36+64 = c²

100 = c²

c = √100

c= 10

Hope this helped and brainliest please

The area, A, of the rectangle below is 3/4 square ft. If A = length x width, what is the length of the rectangle?
Setler [38]

Answer:

\frac{3}{4w} =l

Step-by-step explanation:

The area of a rectangle is found using the formula A = l*w. We know the area is A = 3/4 square foot. To find the length in terms of w, solve for l by multiplying by the reciprocal of w.

A = l*w\\\frac{3}{4} =l*w\\\frac{3}{4} *\frac{1}{w} = l\\\frac{3}{4w} =l
