Answer:
25$
Step-by-step explanation:
7.50$ divided by 3 is 2.50$. then 2.50$ times 10 is 25$
Answer: 8.856cm
Step-by-step explanation:
To solve the question, we will use the formula:
Sin 41° = opposite / hypothenuse
0.656 = opposite / hypotenuse
0.656 = AB / 13.5
Cross. Multiply
AB = 13.5 × 0.656
AB = 8.856cm
5x-2y=6
Slope intercept form y = mx + b
So
5x-2y=6
2y = 5x - 6
y = 5/2 x - 3
Answer
Slope intercept form: y = 5/2 x - 3
Answer:
2000 meters
Step-by-step explanation:
From the above question
Total time = 15 minutes
Converting minutes to seconds
1 minute = 60 sec
15 minutes = x
Cross Multiply
x = 60 × 15 = 900 seconds
Hence, 900 seconds = Total time
Total time = Time to the marker + Time from the marker
From the question, we are given the Speed to the marker = 5 m/s
Speed from the marker = 4 m/s
Time = Distance/speed
Let the distance be represented by x
Hence:
x/4 + x/5 =900
Multiply all through equation by Lowest Common Denominator = 20
5x + 4x= 900×20
9x = 900 ×20
Divide both sides by 9
9x/9 = 900 × 20/9
x = 2000 meters
Therefore, the total distance to the marker = 2000 meters
Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
