Adrianne is planning to bake some chocolate, strawberry, and raisin muffins for a party. She was asked to bake half as many choc
Genrish500 [490]

Answer: She can bake 160 raisin muffins.


Step-by-step explanation:

Let the number of raisin muffins be 'x', then

The number of chocolate muffins = \frac{1}{2}x

The number of strawberry muffins=3\times(\frac{x}{2})=\frac{3x}{2}

Since, the total muffins she can bake 480.

Therefore,

x+\frac{x}{2}+\frac{3x}{2}=480\\\Rightarrow\frac{2x+x+3x}{2}=480\\\Rightarrow\frac{6x}{2}=480\\\Rightarrow\ x=\frac{480\times2}{6}\\\Rightarrow\ x=160

Hence, she can bake 160 raisin muffins.

mart [117]

Answer:

157.6m

Step-by-step explanation:

Given

Horizontal distance = 181m

Length of the rope =240m

To know how high above Kayla was, we will use the Pythagoras theorem.

According to the theorem;

d² = x²+y²

x is the horizontal distance

y is the vertical distance

d is the length of the rope

Substitute

240² = 181²+y²

y² = 240²-181²

y² = 24839

y = √24839

y = 157.6m

Hence the boat is 157.6m above Kayla
