90 mins + 50 mins = 140 mins
60 mins ==1 hr 2*60 = 120 mins
140 mins -120 mins= 20 mins
2 hrs ans 20 mins is the answer
This is vague. Any dimensions that make a triangle can make more than one, just draw another right next to it. What's really being asked is which dimensions can make more than one non-congruent triangle.
<span>A. Three angles measuring 75°,45°, and 60°.
That's three angles, and 75+45+60 = 180, so it's a legit triangle. The angles don't determine the sides, so we have whole family of similar triangles with these dimensions. TRUE
<span>B. 3 sides measuring 7, 10, 12?
</span>Three sides determine the triangles size and shape uniquely; FALSE
<em>C. Three angles measuring 40</em></span><span><em>°</em></span><em>, 50°</em><span><em>, and 60°? </em>
40+50+60=150, no such triangle exists. FALSE
<em>D. 3 sides measuring 3,4,and 5</em>
Again, three sides uniquely determine a triangle's size and shape; FALSE

Answer:
Step-by-step explanation:
Consider an element 
We know that 
Here, m and n are exponents and a is a base. Exponent refers to the no. of times a term is multiplied by itself. Another word for exponents is powers.
Other Properties of exponents:
Here, we are required to divide 
by 
.
Consider 
We will solve 
separately.
Here,
So,
Part A
Distribute the one-half.
1.24g + 0.87m + 0.98z
Part B
(29.68 - x) + 14.45
Or simplified to 44.13 - x
Part C
a = number of times at the store
b = gloves' price
c = hat's price
