Answer:
We know that:
She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)
She only has 1/3 of the amount she needs.
How much flour does she have?
Well, she needs 9/10 grams, and she has one-third of that.
Then she has (1/3) times (9/10) grams, this is:
F = (1/3)*(9/10) grams
F = (1*9)/(3*10) grams
F = 9/30 grams
That is the amount of flour that she has.
Answer:
51° and 96°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
Angle 17x - 1 is an exterior angle, thus
17x - 1 = 33 + 10x + 1, that is
17x - 1 = 10x + 34 ( subtract 10x from both sides )
7x - 1 = 34 ( add 1 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Hence
∠PQR = 10x + 1 = (10 × 5) + 1 = 50 + 1 = 51°
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for ∠PRQ, that is
∠PRQ = 180° - (33 + 51)° = 180° - 84° = 96°
If V 90 mean √90 or square root of 90 than irrational number is C.
Good luck!!!
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
G(x) is just a reflection of f(x) so if f(x) is positive g(x) is negative and vise versa
