Answer:

x=70 degrees, y= 30 degrees, z=20 degrees

Step-by-step explanation:

110+x=180 => straight angle def.

180-110+40=y => def. of angles in triangle

x( 70 degrees) +90+z=180, z= 20 => angles in triangle

Answer:

x=70

z=20

y=30

Step-by-step explanation:

first find x: the sum of straight angle is 180

x+110=180

x=180-110=70

now find z: the sum of the angles of triangle is 180:

x=70, right angle=90

z+70+90=180

find y:

y+110+40=180

y=180-150=30

z=180-160=20

Factorize completely 3n2 + 15np
Tomtit [17]

The factor of the given expression 3n² + 15np is 3n(n+5p).

<h3>What is factorization?</h3>

Writing a number or other mathematical object as the result of numerous factors—typically smaller or simpler objects of the same kind—is known as factorization or factoring in mathematics.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Given that the expression is 3n² + 15np. The factor of the expression will be calculated as,

E = 3n² + 15np

Take 3n common from the expression,

E = 3n ( n + 3p)

Therefore, the factor of the given expression 3n² + 15np is 3n(n+5p).

A cork in the shape of a cylinder has a radius of 2 cm, a height of 5 cm, and weighs 2.5 grams. Find the volume and density of t
8_murik_8 [283]

For this case we have that by definition, the density is given by:

d = \frac {M} {V}

Where:

M: It is the mass

V: It is the volume

We find the volume of the cylinder:

V = \pi * r ^ 2 * h

Where:

r: It is the radius of the cylinder

h: It is the height

V = \pi * 2 ^ 2 * 5\\V = \pi * 4 * 5\\V = \pi * 20\\V = 62.8 \ cm ^ 3

So the density is:

d = \frac {2.5} {62.8}\\d = 0.04

Answer:

d = 0.04 \frac {g} {cm ^ 3}\\Base area: 4 \pi\\Volume: 62.8 \ cm ^ 3

Helen [10]

Answer: 6 1/5 miles

Step-by-step explanation:

Here's the complete question:

On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.

The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:

= Distance to supermarket = 1¾ + ¼ = 2 miles

Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles

Total distance = 2 + 4 1/5 = 6 1/5 miles
