Answer:
Emilia bought 28 sweets
Step-by-step explanation:
now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.
65-15+10=60 and now just do that simply ratio
E:Z=7:8
E+Z=7x+8x
60=15x
4=x
7x=28=Emilia
8x=32=Zakiah
Accuracy test:
(28+15)+(32-10)=65
28 is 4•7 and 32 is 4•8
I’m not really sure I’m just gonna comment cuz I need to answer other ppl
This kind of exercise can be real drudgery. But it's almost all simple arithmetic, so better you than me. I'll do one of these for you, which will show you how to do the other one.
a). sin · cot / sec
You're supposed to know that [ cotangent = cosine/sine ]
and [ secant = 1/cosine ].
Then the problem becomes
sin · (cos/sin) / (1/cos) = cos²
Aw shucks, I might as well also set up 'b)' for you:
b). cos · csc / tan
You're supposed to know that [ cosecant = 1/sine ]
and [ tangent = sine/cosine ].
Then the problem becomes
cos · (1/sin) / (sin/cos) = (cos/sin)²
Now simply plug in the given values of cos A and sin A .
And may I compliment you on your nail care !
Answer:
1/2
Step-by-step explanation:
substitute -2 for x.
any number to negative power must be flipped. 2^-2 = 1/(2^2) = 1/4
(2)(2^-2) = (2)(1/4) = 2/4 = 1/2
The function, f(t), that represents the number of boxes of paper that still need to be processed after t hours is y = 200t + 1200
The expression will be expressed as a straight line formula:
The standard form of the equation is expressed as y = mt+ b
- m is the slope of the equation or the rate
- b is the intercept
- t will be the time taken
From the question;
Rate "m" = 200 boxes per hour
Amount of box the warehouse received = 1200 boxes
Substitute the give parameters into the formula to have:
y = 200t + 1200
f(t) = 200t + 1200
Hence the function, f(t), that represents the number of boxes of paper that still need to be processed after t hours is y = 200t + 1200
