We solve as follows:
*First: We determine the percentage of store purchases:
*Second: The ratio is obtained as follows:
So, the ratio is 11 to 9 purchases.
Answer:
U = x + 3 and V = 7
Step-by-step explanation:
Let U = x + 3 and V = 7, then:
=> (x + 3)^2 + 14(x + 3) + 49
= (x + 3)^2 + 2*7*(x + 3) + 7^2
= U^2 + 2UV + V^2
= (U + V)^2
(correct)
Answer:
Answer C
−5x3 + 4x2 − 5x; is a polynomial
Step-by-step explanation:
you just use distributive property to simplify, and then you know the closure property demonstrates that when you are adding, subtracting, multiplying, or dividing two polynomials, they will remain polynomials.

Answer:
The coaster’s radius is 5 cm
Step-by-step explanation:
Drink Coaster has a circular shape.
Area of a circle = π*r²
so, area of the drink coaster = π x (Radius of the drink coaster)²
Given that Area of the drink coaster is 78.5 cm²
∴ 78.5 cm² = π*r²
Also we are to use 3.14 for π
∴ 78.5 cm² = 3.14*r²
r² = 78.5 cm² / 3.14
r² = 25 cm²
r = 
cm
r = 5 cm
Hence, the coaster’s radius is 5 cm
Chapter: States of Matter
Ans: Increases ( option a ).
Why ?
Explanation: As when the matter goes from solid to liquid, the process is done by gaining heat energy which results a transformation phase known as <u>melting</u>. Due to this, the particles in solid gain enough kinetic energy which starts random collision with each other, hence causes the expansion of intermolecular spaces.
