Using the table, you are looking at a ratio of 9 Dimes to 6 nickels or 9:6 which can be simplified by dividing each by three (a number they are both divisible by without going into decimals) to get a ratio of 3 dimes for every 2 nickels she has, or 3:2
<span>The question says,'which one of the following characteristics of a solid is of concern in geometry. The correct option is C. This is because, geometry is an aspect of mathematics that deals wiht shape, size and properties of solids. It involves the visual study of shape and thier sizes in different positions in space.</span>
Answer:
angle 1 = 111
angle 2 = 69
Step-by-step explanation:
Supplementary Angles add up to 180°.
We are given angle 1 = (x+88)° and angle 2 = 3x°
The sum of both angles add up to 180°
x+88+3x=180
4x=180-88
4x=92
x = 23
To find angle 1, substitute x = 23 in (x+88)°
23°+88° = 111°
Therefore, angle 1 is 111°
To find angle 2, substitute x = 23 on 3x°
3(23) = 69°
Checking if the answer is right by combining 111 and 69.
111+69 = 180
Hence, the answers are 111° and 69°.
Answer:
4.8 units^2
Step-by-step explanation:
Hello! To find the area of this triangle, we need to know both the base and the height. Neither is specifically given.
We can find the height (CD) as follows:
3^2 - 1.8^2 = 5.76, so CD has the length sqrt(5.76) = 2.4.
Triangles ACD and ABC are similar. Therefore, the following equatin of ratios holds:
1.8 CD 2.4
----- = ------- = --------
3.0 AB AB
Then 1.8AB = 3.0(2.4), or AB = 7.2/1.8 = 4.
So the height of triangle ABC is 2.4 units and the length of the base is 4 units.
Therefore, the area of this triangle is A = (1/2)(base)(height), or
A = (1/2)(4 units)(2.4 units) = 4.8 units^2
Answer:
multiplier
Step-by-step explanation:
You get from a distribution. for example 2 (a + b) = (2a) + (2b) which has happened in this problem. It turns out the same if I make a sum of the subsequent parenthesis of a multiplication
