Answer:

308 Calories

Step-by-step explanation:

So we start off with 280 as usual, but I will focus on the percent. The given percent is 110% "effort". What we would need to do here is, Firstly, change the percent into a decimal, and this is done by moving the decimal spot of 110%. What I mean is that 110.% and you move that little period over 2 times to the left and also remove the percent as for now because we will not need it. After that you would get 1.10. This is what we will multiply by. So if we did 280x1.10 it equals 308, and that is how I got 308

Hope this helps!

165\15= number of tubs

165 divided by 15 equals the amount of the tubs that he sold.

What is Question I (if m<EBF = 117°, fine m<ABE)​
Natasha_Volkova [10]

Answer:

m∠ABE = 27°

Step-by-step explanation:

* Lets look to the figure to solve the problem

- AC is a line

- Ray BF intersects the line AC at B

- Ray BF ⊥ line AC

∴ ∠ABF and ∠CBF are right angles

∴ m∠ABF = m∠CBF = 90°

- Rays BE and BD intersect the line AC at B

∵ m∠ABE = m∠DBE ⇒ have same symbol on the figure

∴ BE is the bisector of angle ABD

∵ m∠EBF = 117°

∵ m∠EBF = m∠ABE + m∠ABF

∵ m∠ABF = 90°

∴ 117° = m∠ABE + 90°

- Subtract 90 from both sides

∴ m∠ABE = 27°

Brad wants to buy flowers for his friend with $33. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies tha
Darina [25.2K]

Let x=the amount of roses that Brad buys. (x+3)=the number of daisies that Brad buys.


x+(x+3)=33


Simplify this problem to find the amount of roses:


2x+3=33


2x=30


x=15


So, Brad buys 15 roses and 18 daisies.


Since roses cost $3, 15*3=45.


The roses cost $45.


Hope this helps! :)
