Answer:

1.875ml

Step-by-step explanation:

De la pregunta anterior, podemos decir que:

80 mg = 3 ml

50 mg = x ml

Cruzamos multiplicar

80 mg × xml = 50 mg × 3ml

xml = 50 mg × 3 ml / 80 mg

xml = 1.875ml

Por tanto, se deben aplicar 1.875ml de gentamicina para administrar una dosis de 50 mg.

Answer:

x=11

Step-by-step explanation:

3x-24=9

3x=9+24

3x=33

Answer:

3 nickels and 5 dimes

Step-by-step explanation:

3 nickels = 15 cents

5 dimes = 50 cents

50 + 15 = 65 cents

Answer:

5 dimes and 3 nickels

Step-by-step explanation:

5 times 10 is 50

3 times 5 is 15

15 plus 50 is 65

Answer:

True

Step-by-step explanation:

it is 3/5. Than 6/10 is equal to 3/5. Than 9/15 is equal to 3/5.

Answer: True

Step-by-step explanation:

That is true because let's take the first point for example.

3 cups of almonds for 5 cups of oats.

3/5 of 5 is 3

So that's correct.

If you still aren't sure you should try that with a different point. Hmm how about :

9 cups of almonds for 15 cups of oats

3/5 of 15 = 45/5 = 9

That's correct as well.

Hope these helps!

Answer:

The solution of the first image is: b = √48

The solution of the second image is: c = √125

Step-by-step explanation:

Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.

For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:

A^2 + B^2 = H^2

Where H is the side that is opposite to the right angle (the angle of 90°)

In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.

We want to find the value of b, that is the other cathetus.

Then we have:

4^2 + b^2 = 8^2

b^2 = 8^2 - 4^2

b^2 = 48

b = √48

Second image:

in this case, c is the hypotenuse, a and b are the cathetus.

We know that:

a = 5, b = 10

Then we have the equation:

a^2 + b^2 = c^2

Now we can replace the above values:

5^2 + 10^2 = c^2

25 + 100 = c^2

125 = c^2

√125 = c

Answer:

c. 45

Answer:

40

Step-by-step explanation:

90 degree angle - the 10 degrees = 80

divide by 2 because 2x=80 and get 40

Answer:

4 ÷ 10

Step-by-step explanation:

The computation of P is shown below:

If we add two marbles i.e.

= 4 + 6

= 10 marbles

Now if we draw the second marble

P(blue) = Blue marbles ÷ total marbles

= 4 ÷ 10

In the other case

P( blue second given a green first) = 4 ÷ 10

Answer:

C

Step-by-step explanation:

C, because if you just have a random variable like x,y,z there's always an imaginary 1 in front of them.

Answer: -3

Step-by-step explanation:

y = mx + b (slope intercept formula)

9x - 3y = -54

-3y = 9x - 54

Divide all by -3

y = -3x + 18

Slope = -3

Answer:

p= 1/4 or 0.25

Step-by-step explanation:

Answer:

p = 1/4 or .25

Step-by-step explanation:

We first multiply by the reciprocal of fraction to move to the other side.

[tex]p + 1 = \frac{5}{4} [/tex]

Reduce

p = 1/4

Answer:

x = 5

y = 7

Step-by-step explanation:

Since they are both equal to y, we can set them equal to each other.

2x - 3 = x + 2

Combine like terms and isolate the x.

x = 5

Plug in the x to either equation to get the value of y.

y = (5) + 2

y = 7

Answer:

Each notebook would cost around $4

Step-by-step explanation:

24-12=12

seeing how you spent $12 on buying 3 books you'd divide

12÷3=4

meaning each book would cost around $4

Answer:

Each notebook cost $

Step-by-step explanation:

Hi :)

If the three books in total cost $12, then that means she had $12 leftover.

The equation:

3x + 12 = 24

-12 on both sides

3x = 12

divide by three on both sides

x = 4

hope this helps :)

Answer:

you can because the real cube root of any negative real number is negative.

Step-by-step explanation:

Answer: The reason that we can't have the square (or quartic) root of a negative number is that two negatives always cancel to give a plus; so the square root of a negative number is undefined. ... The Real cube root of any negative Real number is negative.bc. a negativ number multiplied by it self 3 time result negativ too

Answer:

11200 for 7 engines for a total of 80 hours

Step-by-step explanation:

You have 8 engines burning 12000 .for 10 hours.

Divide 10 hours into 12000=1200 PER hour.

1200 ÷8 engines = 140 per hour per engine.

140 × # of hours (12)=1680 for 12 hours per engine.

# of engines × 1680 for 12 hour/per engine

5×1680 = 8400 of fuel for 12 hours/5 engine

Then you have 2 that runs 10 hours

2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours

8400. + 2800= 11200 of fuel for 6 engines

Answer:

Isabelle sold 60% of the corn on Saturday

Step-by-step explanation:

In order to calculate the percentage of the corn that Isabelle sold we first need to divide the number of corn that she sold by the total number of corn that she had initially.

150 / 250 = 0.6

Now we simply need to multiply this decimal value by 100. This will give us the percentage of corn sold as a percentage value.

0.60 * 100 = 60%

Therefore, we can see that Isabelle sold 60% of the corn on Saturday
