Really hard, buy I'll try to solve. um,since WX and YZ are perpendicular, you have to multiply since its a 90° right angle. I hoped I helped :) can I be brainliest it will make my day :)
Answer:
c) (-3s) - 9
Step-by-step explanation:
(-5s) + 2s - 9
-5s + 2s - 9 <== combine like terms
-3s - 9
Therefore, our answer is c.
Hope this helps!
Answer: 28.26 meters
Step-by-step explanation:
Hi, to answer this question we have to find the perimeter of the semicircle.
P = (2 π r ) /2 (perimeter of a circle divided by 2)
The length of AB is the diameter of the circle (18 meters)
Since
Diameter (d) = 2 radius (r)
Replacing with the value given:
18 =2r
18/2=r
9 =r
Back on the perimeter formula
P = (2 π r ) /2
Replacing with the values given
P = (2 x 3.14 x 9) /2
P = 28.26 meters
We can notice from the figure that : Area of the home plate is equal to sum of the Area of the rectangle ( 8 in x 15 in) and Area of the triangle with height 6 in and base 15 in.
Area of the rectangle : Length x Width
⇒ Area of the rectangle = 15 x 8 = 120 in²
Area of the triangle : 1/2 x Base x Height
⇒ Area of the triangle = 1/2 x 15 x 6 = 45 in²
Area of the home plate = Area of rectangle + Area of triangle
⇒ Area of the home plate = 120 in² + 45 in² = 165 in²
<u>Answer</u> : D
The answer is 0.2450
To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied.
In this situation, we have two events occurring simultaneously:
1. Nathan is not allergic to penicillin. The probability that Nathan is not allergic to penicillin is:
1 - the probability of having the allergy.
If the probability of having the allergy is 75% = 0.75, then the probability that Nathan is not allergic to penicillin is:
1 - 0.75 = 0.25
2. The probability that the test is accurate: 98% = 0.98
By using the multiplication rule:
0.25 × 0.98 = 0.245
Therefore, the probability after the test that Nathan is not allergic to the drug is 0.245 = 24.5%.
