A. 45m - 30/4 _> 275 B. 45m/4 - 30 _>275 C. 45m - 30/4 _< 275 D. 45m/4 - 30 _< 275​

Answer:

Liam has finished 30 of his lessons

Step-by-step explanation:

Jenny has completed 15 out of 20 lessons, which means that she has completed 75% of her lessons. If Liam has completed the same percentage of lessons, then he has completed 30 of his lessons. 40(.75) = 30.

Answer:

2.399

Step-by-step explanation:

Given the trigonometry expression:

tan(sin^-1((-12/13))

We are to find the exact value

tan(sin^-1((-12/13)) = tan(sin^-1((-0.9231))

tan(sin^-1((-12/13)) = tan(-67.38)

Also note that tan(-theta) = -tan theta

tan(-theta) = -tan67.38

tan(-67.38) = -2.399

The exact value is 2.399

Answer:  The slope is 0.

Step-by-step explanation: If the line is horizontal, the slope is 0

The rise is 0.  0 divided by any number is 0.

If the line is vertical, the slope is undefined.

No number can be divided by 0, so mathematicians call this situation "undefined."

Answer:

x=3

Step-by-step explanation:

-5(-6-3x)+8=83

Distribute the -5 to both terms in the parentheses by multiplication, multiply the -5 by the -6 and the -3x.

30+15x+8=83

Add like terms, add the 30 and the 8.

38+15x=83

Subtract 38 from both sides to isolate the x on the left side.

15x=45

Divide by 15 on both sides to solve for x.

x=3

Answer:

∠1 ≅ ∠5, ∠2 ≅ ∠4, ∠3 ≅ ∠6

Answer:

s=-1

Step-by-step explanation:

10=-10s

-1=s

Answer: s = -1

Step-by-step explanation:

7 = -10s - 3 Add three to both sides

10 = -10s. Divide -10 by 10

s = -1

Answer:

173 children tickets were sold and 201 adult tickets were sold

Step-by-step explanation:

Let the number of child ticket sold be x

Let the number of adult ticket sold be y

If the total number of ticket sold is 374, hence;

x +y = 374 .... 1

Also if the ticket cost 3$ per child and 5$ per adult with total cost of $1524, this can be expressed as;

3x + 5y = 1524..... 2

Solve both equations simultaneously

From 1; x = 374 - y ...3

Substitute equation 3 into 2

3(374-y)+5y = 1524

1122-3y+5y = 1524

1122+2y = 1524

2y = 1524 - 1122

2y = 402

y = 402/2

y = 201

Since x = 374-7

x = 374 - 201

x = 173

Hence 173 children tickets were sold and 201 adult tickets were sold

Answer:

-3g + 3

Step-by-step explanation:

-9g + 6g + 3

combine like terms

-3g + 3

Hope this Helps!!!

Answer:

-3g + 3

Step-by-step explanation:

This would be the answer because if we add 6g to -9g then we would have -3g since 3  and 3 are not like terms then we can just add them like this -3g+3

Answer:

-14+21x

Step-by-step explanation:

Distrubute

-7 times 2= -14

-7 times 3x= -21x

Answer:

The answer is -14 + 21x

Step-by-step explanation:

Distribute -7 to 2 and -3x

-7 × 2 = -14

-7 × - 3x = 21x

= -14 + 21x

Answer:

7 Artichokes

Step-by-step explanation:

To figure this out, we need to find out how much Vitamin C an average adult needs. We set up a proportion.

[tex]\frac{9}{15} = \frac{x}{100}[/tex]

[tex]15x=900[/tex]

[tex]x=60[/tex]

Now, since each artichoke is worth 9 milligrams, we divide 60 by 9.

[tex]60/9=6.66666...[/tex]

So, to get the necessary amount of Vitamin C, we round up to 7.

Answer:

4,000 bottles.

Step-by-step explanation:

Given that the patient needs a total dose of 50 grams of albumin, and the pharmacy has bottles of 50 milligrams with 25% albumin, to determine how many bottles the patient should purchase the following calculation must be performed:

1 g = 1000 mg

50 g = 50,000 mg

50 x 0.25 = 12.5

50,000 / 12.5 = X

4,000 = X

Therefore, the patient must purchase 4,000 bottles to obtain the required dosage.
