Answer is c
a and d are crossed off because the action of going up and down is adding and subtracting. Absolute values of any number is a positive. So b and c are left. Then b is crossed out because the is subtracting each value from another which affects the result. Negatives change signs. Positives don't. So you want an equation that sums up all individual values without affect the signs. Answer is C.
Let x=small rugs and y=medium rugs. It takes 8 hours to dye a small rug, so you would write 8x. It takes 12 hours to dye a small rug, so you would write 12y. Those two would need to be added together. The dyer needs to dye at least 22 rugs in 240 hours, so you would need a less than or = to sign.
I'm not sure which choice has the line beneath, indicating that the sign is a "less than or equal to" sign, but the answer is gonna be either C or D.
8x+12y≤240, or 12y+8x<span>≤240</span>
Answer:
400+100 = 500
Step-by-step explanation:
ya thats the sum
Step-by-step explanation: We are given to find the value of x from the following trigonometric equation:
sin55=cosx
We know that the sine of any acute angle is equal to the cosine of its complement and cosine of any acute angle is equal to the sine of its complement.So, from equation (i), we get
sin55 ∘ =cosx
⇒sin55 ∘ =sin(90 ∘−x)
⇒55 ∘ =90 ∘ −x
⇒x=90 ∘ −55 ∘
⇒x=35 ∘
Thus, the required value of x is 35°.
17 degrees. 180- 95-34 =51. 51/3= 17
