Answer:
9/12 is equal to 3/4.
Step-by-step explanation:
9 and 12 can both be divided by 3. In the fraction, divide both the top and the bottom by 3 and you get 3/4.
9/12 simplified is 3/4.
I suspect where Chris went wrong was that he though 9 divided by 2 was 3. In reality, it's 4.5.
Maybe he went wrong because he accidentally divided 12 by 2 instead of 3.
Answer:
angle 3 = 60
Step-by-step explanation:
60-60-60 triangle rule
this triangle has 2 60 degree angles so it fits this rule
equilateral traingle
<u>or </u>
a triangle has a total of 180 degrees
so:
180-(60+60)
180-120
60
Answer:
B.
Step-by-step explanation:
Answer:
4 inches
Step-by-step explanation:
<u>Triangular prism formulas</u>
Volume = 0.5 * b * h * length, where b is the length of the base of the triangle, h is the height of the triangle and length is prism length. area = length * (a + b + c) + (2 * base_area) , where a, b, c are sides of the triangle and base_area is the triangular base area.
<u />
<u>How to find the height of a triangle - formulas</u>
area = b * l / 2, where b is a base, l - length.
so l = 2 * area / b/w-width.
<u>Solve</u>
1/2 x 6 x 8 x ? = 96
2 x 96 = 192
192/8 = 24
24/6 = 4
length = 4 inches
Answer:
A
Step-by-step explanation:
From the first inequality,we got:
11x+4<15
11x<11
x<1
From the second inequality,we got:
12x>-18
x>-3/2
Combine it together we got
-3/2<x<1
