Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
80*
Step-by-step explanation:
We can find the distance that they are at at 10 seconds by multiplying their velocity.
Han - 40 feet away from Clare.
Clare - -50 feet away from Han.
Han and Clare would be -10 feet away from the meeting place at -10 feet.
Answer:
La mayor tiene 61 años.
Step-by-step explanation:
Sea x,y,z la edad de la mayor, intermedio y la menor respectivamente.
Tenemos las siguientes ecuaciones:
(la suma de las edades es 127)
(la mayor tiene 30 años más que la menor)
La frase "y la del intermedio 26 menos que la menor" no tiene sentido, puesto que esto implicaría que la del intermedio es menor que la menor. Luego se asume que la frase ha de ser "y la del intermedio 26 menos que la mayor"
(la del intermedio tiene 26 menos que la mayor).
La segunda ecuación se traduce a x-30 =z. Si reemplazamos todo en la primera ecuación obtenemos
Obtenemos la ecuación
Sumando 56 a ambos lados y dividiendo por 3, obtenemos
Es decir la mayor tiene 61 años.
Answer:
Let the proportion of the $0.20 be x
Then the proportion of the $0.68 is 1−x
Set the target at $0.54
Dropping the unit of measurement ($ ) for now we have
0.20x+(1−x)0.68=1×0.54
0.20x−0.68x+0.68=0.54
−0.48x+0.68=0.54
Lets get rid of the decimals for now and multiply everything by 100
−48x+68=54
48x=68−54
x=1448
x=724 of the blend at $0.20
So the proportion of the $0.68 is 1−724=1724
