Answer:
30 degrees.
Step-by-step explanation:
Let the acute angle be x.
Then as the 2 acute angles in a right triangle sum to 90 degrees,
x = 90 - 60
= 30.
Answer:
$167.2
Step-by-step explanation:
It has been given that the price of a new computer is $800.00 and refurbished computer with the same equipment has a price of $640.00.
Let us find the amount that we will save with a refurbished computer if we put the difference into the savings account for a year using simple interest formula.
, where A= Amount after t years, P=principal amount, r = interest rate (decimal form) and t=time.
Our principal amount will be the difference of prices of new computer and refurbished computer.

Upon substituting our given values in above formula we will get,


Therefore, we will save $167.2 with refurbished computer when we put the difference into the savings account for a year.
we are given
△ABC
we can use area of triangle formula

we have
AB=6
BC=10
m∠B=120°
so, we can plug it

To answer question 12, you first need to know the definition of a <em>prism</em> and a<em> pyramid.
</em>A <em>pyramid </em> is a 3-D structure with one base, whose outer faces are made of triangles, and meet at a single point at the top.
A <em>prism</em> is any 3-D shape with a base of any number of sides, another base with the same amount of sides, and faces joining the two together on every side of the bases.
12.
Shape A is a <em>pyramid</em>, because it has one base, and all the faces join together in at one point.
Shape B is a <em>prism</em>, because it has two bases, and faces joining every side of the bases.
Shape C is a <em>prism.</em>
Shape D is a <em>pyramid.
</em>For #13, you have to know the definition of a cube to figure out the math of how many cubes there are.
A cube is a 3-D shape with six sides, all made up of squares of the same size.
The box has a volume of 120 cubic inches, and each cube is 1 inch. Since every side of a cube is equal, a 1-inch cube is one cubic inch.
This means that a box with a volume of 120 cubic inches will fit 120 of the 1 inch cubes.
1 layer of the cubes, in the diagram, is 8 cubes by 3 cubes, or 24 cubes total.
To find the number of layers needed to fill the box, you divide 120 by 24.
120 ÷ 24 = 5
The answer to #13 is 5 layers.
