Let D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}a) find the D U Eb) find the E n F
Juli2301 [7.4K]
the given sets are,
D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}
now,
D U E = { 4 , 6, 7 , 8, 9}
and'
E intersection F = E n F = {6 , 7)
thus, the answer is
D U E = { 4 , 6, 7 , 8, 9} and
E n F = {6 , 7)
Answer:
<u><em>1: "An equilateral triangle is never an obtuse triangle" & "An equilateral triangle is never an isosceles triangle."
</em></u>
<u><em>
</em></u>
<u><em>2: Acute Isosceles Triangle
</em></u>
<u><em>
</em></u>
<u><em>3: False! Option B.
</em></u>
<u><em>
</em></u>
<u><em>4: D</em></u>
Step-by-step explanation:
2: Isosceles Triangles have two equal sides. An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
3: An <u>equilateral triangle</u> is a triangle in which all the sides and all the angles are equal.
4: In order for a triangle to be <u>isosceles</u>, it has to have two same sides. For a triangle to be <u>equilateral</u>, all sides and angles need to be the same. Refer to reasoning in Question 2 for next explanation.
Answer:
8 bags
Step-by-step explanation:
You divided them by 20 which gives you 4. So you take the 3 and multiply by 4 which is 12 bags. And then you do the same for your bags which makes you do 2 times 4 which gives you 8. You take 20 - 12 and that leaves you with 8.
