A jewelry store buys small boxes in which to wrap items that they sell. The diagram below shows one of the boxes. Find the later

andrew-mc [135]

Given that length = 14 cm, width = 7 cm, and height(which was not mentioned in the question) is 1.66 cm, we are tasked to find the lateral area and the surface area of the box.
To find the lateral area, we need to add the area of the sides of the 3D figure.
L = 2(1.66)(14) + 2(1.66)(7)
=46.48 + 23.34
=69.72 ≈ 70 cm^2
To find the surface area,
SA = 2(1.66)(14) + 2(1.66)(7) + 2(14)(7)
=46.48 + 23.24 + 196
=265.72 ≈ 266 cm ^2
The answers are 70cm^2 and 266cm^2.

1. In triangle XYZ, A is the midpoint of XY, B is the midpoint of YZ, and C is the midpoint of XZ. Also, AY = 7, BZ = 8, and XZ

Varvara68 [4.7K]

Answer:

Part 1) The perimeter of triangle ABC is 24 units

Part 2) $y=97\°$

Step-by-step explanation:

Part 1) we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

see the attached figure to better understand the problem

Applying the midpoint theorem

step 1

Find the value of BC

$BC=\frac{1}{2}XY$

$XY=2AY$ ---> because A is the midpoint

substitute the given value of AY

$XY=2(7)=14\ units$

$BC=\frac{1}{2}(14)=7\ units$

step 2

Find the value of AC

$AC=\frac{1}{2}YZ$

$YZ=2BZ$ ---> because B is the midpoint

substitute the given value of BZ

$YZ=2(8)=16\ units$

$AC=\frac{1}{2}(16)=8\ units$

step 3

Find the value of AB

$AB=\frac{1}{2}XZ$

substitute the given value of XZ

$AB=\frac{1}{2}(18)=9\ units$

step 4

Find the perimeter of triangle ABC

$P=AB+BC+AC$

substitute

$P=9+7+8=24\ units$

Part 2) Find the measure of angle y

step 1

Find the measure of angle z

we know that

The sum of the interior angles in a triangle must be equal to 180 degrees

$55\°+42\°+z=180\°$

solve for z

$97\°+z=180\°$

$z=180\°-97\°$

$z=83\°$

step 2

Find the measure of angle y

we know that

$z+y=180\°$ ----> by supplementary angles (form a linear pair)

we have

$z=83\°$

substitute

$83\°+y=180\°$

solve for y

$y=180\°-83\°$

$y=97\°$

The value of a decimal becomes clearer when the place value is spoken or written as the number it names.

irga5000 [103]

Answer:

The value of a decimal becomes clearer when the place value is spoken or written as the number it names. For example, 0.1 makes more sense if it is read as “one-tenth” rather than “zero point one.”
