<span>Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse. </span>
<span>The triangles are similar (right triangles which share an angle (A), so... </span>
<span>AD/AC = AC/AB </span>
<span>5/6 = 6/AB </span>
<span>AB = 6*6/5 = 36/5 = 7.2 </span>
<span>The answer to the first question is "C" </span>
<span>CD can be found using the Pythagorean theorem... </span>
<span>AD^2 + CD^2 = AC^2 </span>
<span>25 + CD^2 = 36 </span>
<span>CD^2 = 11 </span>
<span>CD = sqrt(11) = 3.3 </span>
Answer:
The answer to your question is 16/49
Step-by-step explanation:
Data
4/7 ÷ 1 3/4
Process
1.- Convert the mixed fractions into improper fractions
1 3/4 = (4 + 3) / 4 = 7/4
2.- Divide
4/7 ÷ 7/4 = 16/49
3.- Simplify
I think it is not possible to simplify.
4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.
4/7 x 4/7 = 16/49
The result is the same.
Answer:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.
Answer:
y = 3x

sorry cant do the graph
Answer : 4/7
Here it's given that Brad's family travelled 2/7 of the total distance to his uncle's house on Saturday . So if we assume the total distance to be 1 , then the remaining distance will be ,
Again it's given that they travelled 4/5 of the remaining distance on Sunday . So , the distance travelled would be ,
Therefore Brad's family travelled 4/7 of the total distance on Sunday .
