Angela decides to recycle a large oatmeal container by using it to hold a friends birthday gift. Then she wraps the container in

Deffense [45]

Answer:

D. 135.37 in²

Step-by-step explanation:

We have that the gift paper consists of two circles and a square.

Thus, we will need to find the area of the circles and the square.

Now, as the diameter of the circle = 4 inches

So, the radius of the circle = $\frac{4}{2}$ = 2 inches

Since, the area of a circle = $\pi r^{2}$

This implies that area of the two circles = $2\times \pi r^{2}$

i.e. Area of the circles = $2\times \pi 2^{2}$

i.e. Area of the circles = $8\pi$

i.e. Area of the two circles = 25.133 in²

Further, one side of the square = 10.5 inches

Thus, the area of the square = $side^{2}$

i.e. Area of the square = $10.5^{2}$

i.e. Area of the square = 110.25 in²

So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².

Hence, the amount of paper used by Angela is 135.37 in².

A biologist is studying a new hybrid tomato. It is known that the seeds of this hybrid tomato have probability 0.70 of germinati

Yuliya22 [10]

Answer:

(A) 0.800

(B) 1.000

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

(A) Number of possible outcomes = 8, number of total outcomes = 10

Probability (exactly 8 seeds will germinate) = 8/10 = 0.800

(B) Probability (at least 8 seeds will germinate) means either 8 seeds will germinate or more than 8 seeds will germinate

Probability (more than 8 seeds will germinate) = 1 - 0.800 = 0.200

Probability (at least 8 seeds will germinate) = 0.800 + 0.200 = 1.000

maks197457 [2]

Answer:

x = 8

Step-by-step explanation:

Let the unknown number be x.

4*(x + (-3)) = 4 + 2x

4x -12 = 4 + 2x

2x = 16

x = 8
