12:15 - 1+1 = 2
12:30 - 2 + 2 = 4
12:45 - 4 + 4 = 8
1 - 8 +8 = 16
1:15.......

Okay so there is 1 cell and it starts doubling at 12:00 every 15 minutes that is 4 times every hour and there is three hours so 4 x 3 = 12 so it doubles 12 times then 12 x 2 = 24 so at 3pm that cell would have multiplied it self into 24 other cells

What type of triangle has side lengths of 4√5, √145 and 19?
Masja [62]

a, b, c - side lengths (a ≤ b ≤ c)

If a^2+b^2 < c^2, then is Obtuse triangle.

If a^2+b^2=c^2, then is Right triangle.

If a^2+b^2 > c^2, then Acute triangle.

a=4\sqrt5,\ b=\sqrt{145},\ c=19\to a < b < c

Check to see if the sum of the first two sides is greater than the third.

a+b=4\sqrt5+\sqrt{145}\approx9+12=21 > 19=c\\\\CORRECT

a\neq b\neq c\neq a, therefore is Scalene triangle.

a^2=(4\sqrt5)^2=4^2(\sqrt5)^2=16(5)=80\\\\b^2=(\sqrt{145})^2=145\\\\c^2=19^2=361\\\\a^2+b^2=80+145=225 < 361=c^2\\\\a^2+b^2 < c^2

It's Obtuse triangle.

A car manufacturer crash tests a certain model of car and measures the impact force. The test and model in question produce impa
SIZIF [17.4K]

Answer:

c.Approximately normal

Step-by-step explanation:

The manufacturer had done some test and the result is that the impact forces of the car are normally distributed. Since the sample of the test will be the same kind of car, then the distribution type of the sample will be normal too. Normal distribution will not be skewed to right or left, the data will look like a symmetrical bell shape.

3.6 (5 x 4) ÷ 3 + 5.0
Yuliya22 [10]

3.6 (5 x 4)  ÷ 3 + 5.0

use the PEMDAS rule

P - parentheses

E - exponents

M - multiplication

D - division

A - addition

S - subtraction

3.6 (5 x 4)  ÷ 3 + 5.0

= 3.6 (20)  ÷ 3 + 5.0

= 72  ÷ 3 + 5.0

= 24 + 5.0

=29

so the final answer would be 29!!

Circle A and circle B are congruent. CD is a chord of both circles. If AB = 8 ft and CD = 6 ft, how long is a radius?
bazaltina [42]

Let us say that the intersection point of lines AB and CD is called point E. The lines AB and CD are perpendicular to each other which also means that the triangle CEB is a right triangle.

Where the line CB is the radius of the circle while the side lengths are half of the whole line segment:

EB = 0.5 AB = 0.5 (8 ft) = 4 ft

CE = 0.5 CD = 0.5 (6 ft) = 3 ft

Now using the hypotenuse formula since the triangle is right triangle, we can find for the radius or line CB:

CB^2 = EB^2 + CE^2

CB^2 = (4 ft)^2 + (3 ft)^2

CB^2 = 16 ft^2 + 9 ft^2

CB^2 = 25 ft^2

<span>CB = 5 ft = radius</span>
