No, it seems like an acute triangle. A Right Triangle has at least one degree of 90
12 necklaces in 2 hours
12/2 = 6
6 necklaces in 1 hour
6/2 = 3
3 necklaces in 1/2 hr
So to make 9 necklaces, it will take Kerion 1 1/2 hours
hope this helps
Answer:
1,81, AND 100
Step-by-step explanation:
A PERFECT SQUARE IS A NUMBER THAT WHEN YOU MULTIPLY A NUMBER BY ITSELF, YOU WILL GET THAT NUMBER
1*1=1
9*9=81
10*10=100
Answer:
16.2, 18,2, 20.2, 22.2, 24.2
Step-by-step explanation:
Let
represent an even interger.
Remeber that even intergers have a distance of 2 from each other.
So next four consecutive intergers are
and
Part 2: Five consective intergers have a sum of 101, and qe must find the numbers so
We plot the points A(-2, 3), B(2, 3), C(5, -2), D(0, -3, and E(-2, -2) and join the points in order, we get the figure as shown in the figure attached. Now we have decompose it in rectangles and triangles so we can see that we get 1 rectangle and 2 triangles. Part A: we get 1 rectangle and 2 triangles. Part b we have to find the length of sides AB and AE. We can count the number of blocks, 1 block equals 1 unit so, AB= 8 units, AE= 10 units. Part c we have to find the area of the figure. So what we do is we find the area of the rectangle and 2 triangles separately and add the areas, so we will get the complete area of the combined shapes. So the area of the rectangle is 80 square units if it’s length x width. The pink triangle = 1/2 *base* height = 1/2 * 14 * 2 = 14 square units. Now the area of the yellow triangle = 1/2 *base* height= 1/2 * 10 * 6 = 30 square units. Now the total area of figure ABCDE = (80 + 14 + 30) square units. So the answer will be 124 square units.
