Solution:
According to the problem, the laptop costs $450 less than the desktop. Let x the cost of the laptop, then we get the following equation:
now, the total finance charge of $409 is from 9% of the cost of the laptop and 6.5% of the cost of the desktop. According to this, we get the following equation:
Applying the distributive property, we get:
now, placing like terms on each side of the equation, we get:
this is equivalent to:
solving for x, we get:
this means that:
The cost of the laptop is x = 2450
and
The cost of the desktop is x+450 = 2450 +450 = 2900.
So that, we can conclude that the correct answer is:
Cost of the laptop = 2450
Cost of the desktop =2900.
Answer:
z = 110
Step-by-step explanation:
The measure of an angle created by the intersection of two secants outside a circle is half the difference of the angles it intercepts. In this it would be:
2x + 15 = 1/2 * (10x + 20 - 80)
We can now solve:
4x + 30 = 10x - 60
30 = 6x - 60
6x = 90
x = 15
This means the values of 10x + 20 is 10(15) + 20, which is 170.
Now, we can add up all the arcs in a circle, which sum to 360 degrees:
360 = z + 170 + 80
360 = z + 250
z = 110

only thats not an option so choose E because its the closest
hopefully this helps!!!
.81 and 2.63 if you divide them
Answer:
112.25
Step-by-step explanation:
The total of IQ points for all people in the group was ...
84 × 113 = 9492
Of those points, 36 × 114 = 4104 came from the males. Then the female IQ points were ...
9492 -4104 = 5388
and the female average was ...
5388/(84-36) = 5388/48 = 112.25
The average IQ of the females in this group was 112.25.
