Answer: calculations in seconds (or calculations in seconds)
Step-by-step explanation:
The complete exercise is: "A certain computer can perform 10^5 calculations per second. How many calculations can it perform in 10 seconds".
You need to analize the information provided in the exercise in order to solve it.
Let be "x" the number of calculation a certain computer can perform is ten seconds.
According to the exercise this computer can perform calculations in second. Then, in order to calculate the amount of calculattion it performs in seconds, you can set up the following proportion:
Now, you need to find the value of "x".
To solve for "x" you can multiply both sides of the equation by .
Then, you get:
Therefore, the computer can perform calculations in seconds (or calculations in seconds)

Answer: -1, 2
Step-by-step explanation: y = 3y - 7+1
y = 3y - 6
6 = 3y
y = 2
Now, substitute 2 back into the equation to find out x and get (-1, 2)
The solution of the system above can be solved using substitution method of solving equations. The value of y = 3, X = 4.
How to solve the system of equations?The equations given ;
X = 3y -7 ---> equation 1
y = X + 1 ---> equation 2
Substitute equation 1 into equation 2
That is;
y = 3y - 7 + 1
y - 3y = -7+1
-2y = -6
y = -6/-2
y = 3
Substitute y = 3 into equation 2;
3 = X - 1
X = 3+1
X = 4

6. The triangles shown are congruent. Find the measure of P.
A 43
B 32
C 105
D 37.5
Answer: B-32
Step-by-step explanation:
Hello! All angles of a triangle add up to 180 degrees. Since triangles add up to 180 degrees, you know that the measure of angle m in the first triangle is 105 degrees. Because all sides in congruent triangles and all angles in congruent triangles are also congruent, you know that the second triangle has to have the same angle measurements as the first. P or Q could have the angle measurements of 32 degrees or 43 degrees. Q is the angle with 43 degrees because it is clearly the longer side and looks like the first triangle's side with 43 degrees. P is the angle with 32 degrees because it is the shorter side.

Are the ratios
25/45
and
15/27
proportional? Explain.
Answer:
Yes
Step-by-step explanation:
First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).
First ratio becomes (25:5)/(45:5) = 5/9
Second ratio becomes (15:3)/(27:3) = 5/9
Since we can simplify them in that way that both are the same that means they are proportional.
because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
Answer:
Yes
Step-by-step explanation:
If you divide 25/45 by 5 you get 5/9
Then you divide 15/27 by 3 you also get 5/9
Since both are equal to 5/9 they are proportional.

y=2x-7 4x+y=11 which ordered pair makes both equations true
Answer:
x=3 y=-1
Step-by-step explanation:
substitute into one of the equations: 4x+2x-7=11
rearrange unknown terms to the left side of the equation: 4x+2x=11+7
combine like terms: 6x=18
divide both sides by x: x=18/6
calculate to product: x=3
Same thing for y:
y=2x3-7
y=6-7
y=-1
Solution:
x=3
y=-1

A fair coin is tossed three times. What is P(tossing at least two tails)?
A: one eighth
B: one fourth
C: three eighths
D: one half
Answer:
one eighth
Step by step explanation:
Let us mark H for Heads and T for Tails.
The coin is flipped three times; the total
number of outcomes = 2 * 2 * 2 = 8 .
Sample Space (| Omega|)=\ (H, H, H), (H, H, T) ,(H,T,
H ),(H,T,T),(T,H,H),(T,H,T),(T,T,H),(T,T,T)\
= 8
Let X be the probability of getting all tails: X
= \{(T, T, T)\}
=> |X| = 1
P(X) = IXI/IQI = 1/8.
Thus, the probability of flipping a coin three times and getting 3 tails is 1/8.
Answer:
D: one half
Step-by-step explanation:
You want the probability of tossing at least two tails when a fair coin is tossed 3 times.
OutcomesThe outcomes from the tosses will be one of ...
TTT, TTH, THT, THH, HTT, HTH, HHT, HHH
Of the 8 possible outcomes, the 4 that are highlighted have at least 2 tails.
D: The probability of tossing at least 2 tails is 4/8 = 1/2.

Answer:the hat was 14$
Step-by-step explanation: count the money then count the money on the other side see how much money is taken away and there you go that is how much it was
X = $14
Paul starts out with $2. All that you have to do is subtract $6 the amount he has after buying the hat, from $20.
$20 - $6 = $14
or
$20 - X =$6 (in the end you would find out x = 14)
