Now box is 3/4 full


3/4 = 3/4*1


3/4 = 3/4 * 3/3 = 9/12


Box is 9/12 full after heba ate 1/12 of a box of cereal


Initial fraction will be 9/12+1/12


=10/12= 5/6

Answer:

5/6.

Step-by-step explanation:

If Heba ate 1/12 of a box of cereal and the box is now 3/4 full, then before she ate the box is 3/4 plus the 1/12 (because, in the "before" situation she hasn't eaten yet). So, we need to add the "now" quantity and the quantity eaten:

\frac{3}{4}+\frac{1}{12} = \frac{10}{12} = \frac{5}{6}.

Then, before she ate the cereal, the box is 5/6 full.

If the graph of f(x) = |x| is shifted up 5 units, what would be the equation of the new graph?
inna [77]

Answer:

B. g(x)= |x| + 5

Step-by-step explanation:

-5 represents a vertical shift down, so that narrows it down to either A or B. A shows a shift across the horizontal (X) axis, so it must be B.

Find the area of the figure. Round to the nearest hundredth when necessary.
Delvig [45]

Answer:

215.20 ft^2

Step-by-step explanation:

The figure has 2 semi-circles.

First we find the area of each circle using the formula \pi r^{2} because that is the area formula for a circle.

The semi-circle to the left gives the diameter which is 22 feet. The radius would be half the diameter thus r=11 for semi-circle one.

Then we are to find the diameter of the second semi-circle. Given the entire length to be 30 feet, 30-22 leaves us with 8 feet as its diameter thus r=4.

Left: r=11

Right: r=4

Then, plugging both into the formula for area of a circle, we get

Left: 380.1327

Right: 50.26548

We must divide each by two because we are only looking for semi-circle which is exactly half the area of a full circle.

Then,

Left: 190.066

Right: 25.1327

190.066+ 25.1327= 215.199 = 215.2ft^2
