Answer:
.
Step-by-step explanation:
Given:
Tina cut 3 wood boards each into 4 equal pieces.
She used 3 of the pieces for a craft.
Question asked:
What fraction of the boards does she have left ?
Write this fraction as a mixed number.
Solution:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces = 
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3>
<u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3>
<u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute = 
9 pieces constitute = 
<em>Now, convert it into mixed fraction:</em>
Therefore, fraction of the boards she have left is .
Answer:
points A,F, & G
Explanation:
They lie on same line l. By definition they are collinear.
Answer:
1.5 liters
Step-by-step explanation:
we have
x ------> the number of days
y -----> the amount of water collected in liters
To find out how much water is collected by day, determine the slope of the linear equation
The formula to calculate the slope between two points is equal to
Observing the graph
we have
(0,2) and (4,8)
substitute the values in the formula
therefore
The amount of water collected is 1.5 liter by day
Answer:
C. Yes, the density equals that of pure silver (10.5)
Step-by-step explanation:
Answer:
Coordinate of K: (3, 1)
Step-by-step explanation:
The rule
(x + 1, y + 5) tells us
Add 1 to x point (coordinate)
and
Add 5 to y point (coordinate)
Lets look at the diagram and figure out the coordinates of K:
From origin, we go 2 units right and 4 units down, so coordinate of K is:
(2, -4)
Now we apply the rule:
(2 + 1, -4 + 5)
= (3, 1)
The new coordinates of K will be:
<u>(3, 1)</u>
