Answer
A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is : a to b, a over b, and a:b
Answer:
Step-by-step explanation:
Total she can make = 11
Amount she has already made = 3
Amount she still have to make = 11-3 = 8
% of the 20blanket she still have to make = 8/20×100
= 8×5
= 40%
Hence she Still need to make 40% of the 20blanket
Answer:
1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.
Step-by-step explanation:
Given: Jamal Sliced aright circular cylinder into congruent pieces.
To find: Shape of Two-Dimensional plane section obtained after slicing.
We get congruent pieces only when we slice the cylinder parallel to its base at equal heights.
By doing this we get small pieces of cylinders of equal height and equal radius.
Base and top remains same that is circular in shape.
Therefore, 1st Option is correct that is we get circle after slicing a right circular cylinder in small pieces.
248 to 370 gems
set up two equations
132=(1/2)x+8 x=248
193=(1/2)x+8 x=370
Factor: Trying to factor by splitting the middle term
The first term is 15a^2, its' coefficient is 15
The middle term is - 58a, its' coefficient is - 58a
The last term is "The Constant" is +48
Multiply the coefficient of the first term by the constant 15(48) = 720
Find two factors of 720, whose sum equals the coefficient of the middle term, which is -58

Factoring: 15a^2 - 58a + 48 = 0
Factor left side of equation:
(5a - 6)(3a - 8)
Set fractions equal to Zero
5a - 6 = 0 or 3a - 8 = 0
Answer : a = 6/5 = 1.200
or a = 8/3 = 2.667
Hope that helps!!!!
