Answer: 195 yd²

Step-by-step explanation:

Area of a rhombus is 1/2 of the product of the diagonals.

Given: diagonal 1 = 7.5 + 7.5 = 15

diagonal 2 = 13 + 13 = 26

A = (1/2) × 15 × 26

= 195

Answer:

$195$ yd^2

Step-by-step explanation:

Formula: $A = \frac{pq}{2}$

p = 7.5 + 7.5 = 15

q = 13 + 13 = 26

$A = \frac{26*15}{2}$

A = 195

Write the equation for (-8, -8), with a slope if three

valentina_108 [34]

Answer:

Part--1:

We know that a equation in point-slope form is represented by:

 y-y1=m

where m is the slope of the line and is a point through which the line passes.

 

Consider a equation in a point-slope form as:

This means that the slope of the line is: 5

and the line passes through the point (1,5).

Part--2:

Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m

Since,

Let this perpendicular line passes through (2,6)

Hence, the equation of a line in point slope form is given by:

21. Brian wants to purchase a piece of fabric

ella [17]

Brian should purchase Choice C of fabric

Solution:

Given that Brian wants to purchase a piece of fabric that is between 49 and 53 inches long

So piece of fabric should be between: 49 and 53 inches

Choice A is $4\frac{3}{4}$ feet long

Let us convert feet to inches

$4\frac{3}{4} feet = \frac{4 \times 4 + 3}{4} = \frac{19}{4} feet$

Now convert to inches

We know that,

1 feet = 12 inches

$\frac{19}{4} feet = \frac{19}{4} \times 12 = 57 inches$

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Choice B is $4\frac{1}{2}$ feet long

$4\frac{1}{2} feet = \frac{2 \times 4 + 1}{2} = \frac{9}{2} feet$

Now convert to inches

$\frac{9}{2} feet = \frac{9}{2} \times 12 inches = 54 inches$

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Choice C is $4\frac{1}{3}$ feet long

$4\frac{1}{3} feet = \frac{3 \times 4 + 1}{3} = \frac{13}{3} feet$

Now convert to inches

$\frac{13}{3} feet = \frac{13}{3} \times 12 inches = 52 inches$

So this 52 inches lies between 49 and 53 inches

So Brian should purchase Choice C of fabric
