The answer is -11, have a good day
Answer:
The value of N is 12 sq cm.
Step-by-step explanation:
1. Find the greatest common factor of 35 and 42 to find the length (horizontal). The GCF is 7.
2. The horizontal length of the 35 and 42 sq cm is 7, and the heights are 5 and 6 respectively.
3. Moving on tot he 10 sq cm rectangle, since the height of just that one rectangle is and 10/5 is 2, the horizontal length is 2.
4. For n, the horizontal length is 2 and the height is 6. 2 X 6 is 12 sq cm.
Answer:
Step-by-step explanation:
Given that ;
Carlos needs 1.7 meters of wire for one project &
0.8 meters of wire for another project
we are to shade the model to represent the total amount of wire Carlos needs .
NOW;
For both projects ; Carlos needs ( 1.7 + 0.8) meters of wire = 2.5 meters of wire
In the attached files below. the first picture shows the diagram attached to the question and the second one shows the shading of the model which represent the total amount of wire Carlos needs.
Answer:
70 / 3
Step-by-step explanation:
x / 7 = 10 / 3
x = ( 10 / 3 ) x 7
= ( 10 x 7 ) / 3
x = 70 / 3
<span>pHProblem 4- Determine the hydrogen concentration of bloodTutorial to help you with this calculation.<span>4.What is the approximate hydrogen ion concentration of blood with pH 7.4?</span><span> <span><span>TutorialIn this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,− pH = log [H+] ,[H+] = 10−pH,by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M. </span></span></span></span>
