4.4a-7.3 is equal to
4.4a= 7.3 divide both sides by 4.4
a= 1.66
Answer:
x = 68 degrees
Step-by-step explanation:
Step 1: We know this is a isosceles triangle
Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59
Step 2: Use the 2 angles to find 'x'
Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68
Therefore angle x is 68 degrees
Given that the volume of a cell is 50 cubic micrometers. It says to find the number of cells present in 1 cubic centimeter.
So we need to first convert the units of volume of a cell, then we can find the total number of cells in 1 cubic centimeter.
We know 1 meter = 100 centimeters = 1000000 micrometers
So 1 centimeter = 10000 micrometers
Taking Cubic powers on both sides :-
1 cubic centimeters = 10¹² cubic micrometers
1 cubic micrometers = 10⁻¹² cubic centimeters
50 cubic micrometers = 50 × 10⁻¹² = 5 × 10⁻¹¹ cubic centimeters
So volume of one cell = 5 × 10⁻¹¹ cubic centimeters
Number of cells =
= 2 × 10¹⁰ cells.
So, total number of cells = 2 × 10¹⁰ cells.
Answer: 7 hr
Step-by-step explanation:
Given
Distance between Emily and Kylie is ![140\ \text{miles}](https://tex.z-dn.net/?f=140%5C%20%5Ctext%7Bmiles%7D)
Speed of Emily ![v_e=12\ mph](https://tex.z-dn.net/?f=v_e%3D12%5C%20mph)
Speed of Kylie ![v_k=8\ mph](https://tex.z-dn.net/?f=v_k%3D8%5C%20mph)
Distance traveled by Emily ![\Rightarrow d_e=12t](https://tex.z-dn.net/?f=%5CRightarrow%20d_e%3D12t)
Distance traveled by Kylie ![\Rightarrow d_k=8t](https://tex.z-dn.net/?f=%5CRightarrow%20d_k%3D8t)
![\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr](https://tex.z-dn.net/?f=%5CRightarrow%2012t%2B8t%3D140%5C%5C%5CRightarrow%2020t%3D140%5C%5C%5CRightarrow%20t%3D7%5C%20hr)
They will meet after 7 hour.
