A large bacterium measures 750 micrometers in diameter. One micrometer = 10 − 6 meters. How would you express the diameter of the bacterium in meters using scientific notation? A. 7 . 5 × 10 − 8 B. 750 × 10 − 6 C. 75 × 10 − 5 D. 7 . 5 × 10 − 4
Answers
Answer:
7.5 * 10^-4
Step-by-step explanation:
To express this, we will have to multiply 750 by the conversion unit
we have this as;
750 * 10^-6
750 = 7.5 * 10^2
so we have;
7.5 * 10^2 * 10^-6
= 7.5 * 10^(-6+2)
= 7.5 * 10^-4
The diameter of the bacterium in meters using scientific notation is 7.50 × 10^-4
Length of the bacterium = 750 micrometersOne micrometer = 10^-6How to write scientific notationMove the decimal point in between the first and second numberCount the number of digits after the decimal pointDiameter of the bacterium in scientific notation = 7.50 × 10²
Recall one micrometer = 10^-6
So
7.50 × 10² × 10^-6
= 7.50 × 10^(2-6)
= 7.50 × 10^-4

in the figure below, <1 measures (3x+20) and <2 measures x. what is the measure of <4?
Answers
Answer:
D. 140
Step-by-step explanation:
∠ 1 + ∠ 2 = 180
So:
(3x + 20) + x = 180
4x + 20 = 180
4x = 180 - 20
4x = 160
x = 160 / 4
x = 40
∠ 1 = ∠ 4
∠ 2 = ∠ 3
If ∠ 1 is equal to ∠ 4, just plug in for x and solve.
3x + 20 = 3(40) + 20 = 120 + 20 = 140

Answer: 135 pi
Step-by-step explanation: I took the test
It is a three-dimensional shape with two parallel circular bases and a curve surface.
The volume of water needed to fill the pool is 180π square feet.
What is a cylinder?It is a three-dimensional shape with two parallel circular bases and a curve surface.
Volume = π r² h
r = radius of the cylinder
h = height of the cylinder
We have,
Diameter of the cylinder = 12 ft
Radius = diameter/2 = 12/2 = 6 ft
Height of the cylinder = 5 ft
The volume of the cylinder:
= πr²h
= π x 6² x 5
= π x 36 x 5
= 180π square feet
Thus,
The volume of water needed to fill the pool is 180π square feet.

Answer:
Obtuse angled triangle
Step-by-step explanation:
If a, b and c are the sides of a triangle with c the largest side
• If a² + b² = c² ⇒ right triangle
• If a² + b² > c² ⇒ acute angled
• If a² + b² < c² ⇒ obtuse angled
Here a = 8, b = 15, c = 23
a² + b² = 8² + 15² = 64 + 225 = 289
c² = 23² = 529
