the length of a rectangle is four times it’s width if the perimeter of the rectangle is 70 yd find it length and width

Answers

Answer:

Step-by-step explanation:

Length = 4 * width

L = 4 * w

70 = Perimeter = 2*Length + 2* width = 2(4w) + 2w = 8w + 2w = 10w

so w=7 --> length is 28.  Note that perimeter is 28+28+7+7 = 56 + 14 = 70

Then the area is 28 x 7 = 196 square inches

In the given figure, the Angle x forms Alternate exterior angle pair with 143°, so

value of x° = 143°

(since, Alternate Exterior Angles have equal measures)

please solve and explain !!!

Answers

Answer:

107

Step-by-step explanation:

Angle 1

When a line is passes through a straight line, the two angles must equal 180 degrees.  Since you know the one angle is 81, then angle 1 is 180 - 81 or

99 degrees.

Angle 2

You can determine the angle that is opposite of the 91 angle.  These two angles must add up to 180.  So the angle to the right of 91 must be 89.

89 + 91 = 180

You were told lines c and d are parallel.  Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.

Angle 3

Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.

So angle 3 is equal to the angle marked as 81 degrees.

Angle 1 + Angle 2 - Angle 3 = 107

[tex]\frac{27}{2}[/tex]

Step-by-step explanation:

Okay, first whenever you divide a fraction, you're going to want to multiply by the reciprocal. The reciprocal or the inverse in this case is [tex]\frac{3}{2}[/tex].

Multiply 9 with the integer. Also, remember that numbers that aren't fractions like 9 can be written as a fraction with a 1 in the denominator. 9 = [tex]\frac{9}{1}[/tex]. So,

[tex]\frac{9}{1}[/tex] × [tex]\frac{3} {2}[/tex]. Multiply across. The numerators together (9 with 3) and the denominators together (2 with 1).

9 × 3 = 27 and 1 × 2 = 2. As a fraction the answer will come out to be [tex]\frac{27}{2}[/tex].
