Answer:

2.5

Step-by-step explanation:

$(a)b-0.5b$

Substitute 'a' and 'b' for the appropriate values:

$(1)5-0.5(5)$

Solve:

$(1)5-0.5(5)\\\\5-2.5\\\\\boxed{2.5}$

Hope this helps.

Answer:

4.5 mL

Step-by-step explanation:

Amount of Acetaminophen prescribed is 15 mg/kg. This means for every 1 kg of the child's weight, 15 mg of Acetaminophen will be administered to the child.

Weight of the child = 9.6 kg

Since, for each 1 kg the amount of Acetaminophen is 15 mg, the amount of Acetaminophen needed for 9.6 kg will be = 9.6 x 15 = 144 mg

Therefore, the child must be administered 144 mg of Acetaminophen in total.

The strength of Acetaminophen is 160mg / 5 mL. This means 5 mL of an injection contains 160 mg of Acetaminophen. But since, the child needs 144 mg, we need to calculate in mL, the volume of injection needed for 144 mg of Acetaminophen.

160 mg of Acetaminophen is present in an injection of volume = 5mL

1 mg of Acetaminophen is present in an injection of volume = $\frac{5}{160}$ mL

144 mg of Acetaminophen is present in an injection of volume = $\frac{5}{160} \times 144 = 4.5$ mL

Thus, 4.5 mL of the injection will contain 144mg of Acetaminophen which would be administered to the patient.

Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of

Lera25 [3.4K]

Check the picture.

Let the given points represent the following:

F : Charlie's feet
E: Charlie's eyes
P: location of the plane
G: the foot of the perpendicular drawn from P to the ground
A: a point on PG, such that |GA|=|FE|=5.2 feet.

Clearly EAP is a right triangle, with m(AEP)=32°, side PA=1,700-5.2=1694.8 feet.

the ground distance from Charlie to the plane is |FG|=|EA|

from right angle trigonometry, we know that:

 $tan32= \frac{PA}{AE}$

 $0.625= \frac{1694.8}{AE}$

 $AE= \frac{1694.8}{0.625}=2711.68$ feet


Answer: 2711.68 feet

Yani buys a certain brand of cereal that costs $10 per box. Yani changes to a super-saving brand of the same size. The equation

anygoal [31]

A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one. Proof:
Suppose 1 box is bought of each (x=1),original will cos10 & the cheaper $7
b) Each time he buys a cheap brand he save $3 ($10-$7), on 5 cheap boxes, he would save $3 x 5 boxes = $15

Find the sample space for a committee of two chosen from Alice (A), Bill (B), Carol (C), and David (D).

Finger [1]

Answer:

(a) C. {(A, B), (A, C), (A, D), (B, C), (B, D), (C, D)}

(b) C. {(A,B),(A,D),(B,C),(C,D)}

Step-by-step explanation:

Given four members eligible for selection:

Alice (A), Bill (B), Carol (C), and David (D).

The possible combinations are:

(A,B),(A,C),(A,D),(B,A),(B,C),(B,D),(C,A),(C,B),(C,D), (D,A),(D,B), (D,C)

Part A

Since the same pairs are equal i.e. (A, B)=(B , A),

The Sample space for a committee of two is:

{(A,B),(A,C),(A,D),(B,C),(B,D),(C,D)}

This is Option C.

Part B

If both genders must be represented, we remove the entries that contain the same gender from the sample space above.

A and C -Female

B and D - Male

{(A,B),(A,C),(A,D),(B,C),(B,D),(C,D)}

Therefore, the sample space if both genders are to be represented is:

{(A,B),(A,D),(B,C),(C,D)}

This is Option C.
