Well according to my calculations if you find ab +3 and then carry the 4 and multiply the 48 then combine the 10b+30c you would eventually find a consisting of many numerals maybe too far to portray over text so I'll cut it down and refer to my lovely friend 1/2

25 pts What is the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down?

BartSMP [9]

Answer:

B

Step-by-step explanation:

1. A reflection across the origin has a rule

$(x,y)\rightarrow (-x,-y).$

2. A translation 9 units to the left and 7 units down has a rule

$(x,y)\rightarrow (x-9,y-7).$

Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is

$(x,y)\rightarrow (-x-9,-y-7).$

This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).

A kitchen drawer has a Volume 1,125 cubic inches. The drawer is 15 inches long and 5 inches deep. What is the width of the drawe

Temka [501]

Answer:

The width of the drawer is $15\ in$

Step-by-step explanation:

we know that

The volume of the drawer is equal to

$V=LWH$

we have

$L=15\ in$

$H=5\ in$ -----> the deep of the drawer

$V=1,125\ in^{3}$

substitute the given values in the formula and solve for W

$1,125=(15)(W)(5)$

$1,125=(75)(W)$

$W=1,125/(75)$

$W=15\ in$

The length of a rectangle is 16 inches. if the width is 25% of its length, what is the perimeter of the rectangle

Leokris [45]

Answer:

Perimeter = 40 inches

Step-by-step explanation:

Length = 16 inches

Width = 25% of length (16)

= 25% of 16

25% = 1/4

Width = 1/4 x 16

= 4 inches

Length = 16 inches

Width = 4 inches

Perimeter of a rectangle = length + length + width + width:

= 16 + 16 + 4 + 4

= 32 + 8

= 40

PERIMETER = 40 inches

So glad I could help :)
