Answer:
1078
Explanation:
For this you can use a proportion to solve. So first we set up the proportion as laptop over desktop is equal to "<em>l</em>" over total desktop computers. Let <em>l</em> be the total amount of laptops which is what we must first solve for.
Then we cross multiply.
Now we can solve it as a regular algebra problem,
Now that we know how many laptop computers there are we can find the total number of computers in the school. We simply add the total number of desktop computers to the total number of laptop computers.
And that is the answer. 1078.
Answer:
106°
Step-by-step explanation:
Given that the points B, C and D are colinear, it means that
2x + 40 = 5x + 10
collecting like terms
40 - 10 = 5x - 2x
3x = 30
x = 10
Hence the angle ∠E
= 5(10) + 10
= 60°
∠BCE = X + 4
= 10 + 4
= 14°
Given that the sum of angles in a triangle is 180°
∠D + 14 + 60 = 180
∠D = 180 - 74
= 106°
Answer:
{x : x > 2}
Step-by-step explanation:
Divide both sides of the inequality by 4. The coefficient of x is 4, so doing this will make the coefficient of x be 1. That is what you want in your expression for the solution set.
... (4x)/4 > 8/4 . . divide by 4
... x > 2 . . . . . . . simplify
Answer:
A matched-pairs hypothesis test for μD
Step-by-step explanation:
The trainer wants to compare each athlete's time before the program to the time after the program. Since we're comparing times for the same athlete, the data is paired, so we should use a matched-pairs test.
Answer: None
Step-by-step explanation:
add 8 on both sides.
Divide by -6 to isolate x.
<u>NOTE:</u> When you multiply or divide by negative numbers, you flip the inequality sign.
