Answer:
B) 24 sq. in.
Step-by-step explanation:
A = (1/2)bh
= (1/2)(8 inches)(6 inches)
= (1/2)(48 sq. in.)
A = 24 sq. in. is the area of the given triangle.
Answer:
the rectangle is 5√6 wide and 10√6 length
Step-by-step explanation:
The dimensions of the larger rectangle are wide and tall
we know that
The ratio of its areas is equal to the scale factor squared
a = factor of scale
b = large rectangle area
c = original rectangle area
a² = b/c
b = 5 x 10 = 50
c = 6 x 50 =300
a² = b/c = 300/50 = 6
a = √6
the rectangle is 5√6 wide and 10√6 length
Answer:
<u>1.8 ounces</u>
Step-by-step explanation:
Let :
⇒ weight of a can of juice = x
⇒ weight of an energy bar = y
=============================================================
Equations formed :
- 3x + 2y = 33.6
- 4y + 2x = 27.2
============================================================
Multiply Equation 1 by 2 :
⇒ 2 × (3x + 2y) = 2 × 33.6
⇒ 6x + 4y = 67.2 [Equation 3]
===========================================================
Subtract : Equation 3 - Equation 2
⇒ 6x + 4y - 4y - 2x = 67.2 - 27.2
⇒ 4x = 40
⇒ <u>x = 10</u>
===========================================================
Finding the weight of an energy bar :
⇒ 3(10) + 2y = 33.6
⇒ 2y = 3.6
⇒ y = <u>1.8 ounces</u>
