the side is in the shape of a rectangle with an area of 437 square centimeters the length of the rectangle is 19 centimeters wha

miss Akunina [59]

The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm

That is the answer.

In△XYZ , XY¯¯¯¯¯¯=7in , YZ¯¯¯¯¯=5in , and XZ¯¯¯¯¯=4in . This triangle is reflected across the x-axis to result in △X'Y'Z' . Whic

ki77a [65]

Answer:

Step-by-step explanation:

Reflection is a transformation that preserves lengths.

Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.

This means that corresponding sides have the same lengths:

XY = X'Y' = 7 in;
XZ = X'Z' = 4 in;
YZ = Y'Z' = 5 in.

Find the perimeters of both triangles:

$P_{XYZ}=XY+XZ+YZ=7+4+5=16\ in\\ \\P_{X'Y'Z'}=X'Y'+X'Z'+Y'Z'=7+4+5=16\ in$

Hence, only option B is true.

Find the product and write in lowest term. Give me an integer or simplified fraction. 7/54×27/35

wariber [46]

The product of given expression is $\frac{1}{15} \text{ or } 0.0667$

Solution:

Given that we have to find the product and write it in lowest term

Given expression is:

$\frac{7}{54} \times \frac{27}{35}$

Let us first find common factors of numerator and denominator so, thet simplification becomes easier

$54 = 27 \times 3\\\\35 = 7 \times 5$

Substituting these in above expression, we get

$\rightarrow \frac{7}{27 \times 3} \times \frac{27}{7 \times 5}$

Cancel the common factors in numerator and denominator

$\rightarrow \frac{1}{15}$

In decimal form, we get

$\rightarrow \frac{1}{15} = 0.0667$

Thus the product of given expression is $\frac{1}{15} \text{ or } 0.0667$

Nancy has a 3.5-pound bag of birdseed. She uses 3/4 of the bag to fill a bird feeder in her garden. Then, she puts 0.25 pounds i

AnnyKZ [126]

Answer:

0.625lb bag of bird seeds

Step-by-step explanation:

She starts with a 3.5 lb bag,

Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;

1/4 * 3.5

= 1/4 * 7/2

= 7/8

Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).

7/8 - 0.25

= 7/8 - 1/4

= 7/8 - 2/8

= 5/8

So she has a 5/8lb bag of bird seeds or a 0.625lb bag.
