C. translation is moving to a different spot. rotation has to have the letters in the same spot when rotating it. reflection is a mirror so its C.
Answer:
One Way: 79 + 62H + 15H = X
Second Way: 79 + ((62 + 15) x H) = X
Step-by-step explanation:
Given that a plumber charges a customer a one-time service fee of $ 79, $ 62 per hour for labor, and a surcharge of $ 15 per hour due to the call being an emergency, to write an expression to represent the total charges for the plumber in two different ways, with H representing the number of hours the job takes, the following equations should be formulated:
79 + 62H + 15H = X
So, for example, if the job had lasted 2 hours, the equation would apply as follows:
79 + 62x2 + 15x2 = X
79 + 124 + 30 = X
233 = X
79 + ((62 + 15) x H) = X
In the case, if the work had lasted 1 hour, the equation would apply as follows:
79 + (62 + 15) x 1) = X
79 + 77 x 1 = X
79 + 77 = X
156 = X
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 2 + 1 = 3 parts , thus
81 cm² ÷ 3 = 27 cm² ← value of 1 part of the ratio
2 parts = 2 × 27 = 54 cm²
Area of A = 54 cm² and area of B = 27 cm²
The side of the original square = = 9 cm
The width of both rectangles is 9 cm ( width remains unchanged after cut )
Thus
Rectangle A
9 × length = 54 ( divide both sides by 9 )
length = 6 cm
Rectangle B
9 × length = 27 ( divide both sides by 9 )
length = 3 cm
Rectangle A → length = 6 cm, width = 9 cm
Rectangle B → length = 3 cm , width = 9 cm
Its a simple unitary method problem…
6 men will do the work in 12 days
1 man will do in 6*12 = 72 days
So, 5 men will do it in 72/5 = 14.4 days
There are two types of relation
<span>Direct relation - If one quantity increases then the other also increases and if one quantity decreases then the other also decreases.</span>
Example- If 3 pencils cost Rs 7, then what will be the cost of 5 pencils ?
3 pencils cost Rs 7
1 pencil will cost Rs 7/3 (First divide)
5 pencils will cost Rs (7/3)*5 = Rs 11.66 (Then Multiply)
<span><span>Inverse relation : </span>If one quantity increases then the other decreases and if one quantity decreases then the other increases.</span>
Example - This question itself is the example of inverse relation. Here first we did multiplication and then division.
I hope it clears the image….
