A doctor has 53 ccs of a 40% solution of a pain killer. How much sterilized water should be added to get a 27% solution?

Answer:

B) 1

Step-by-step explanation:

x+1/2(x-4)=1/2x+6(x-2)

x+1/2x-4/2=1/2x+6x-12

x+1/2x-1/2x-2=6x-12

x-2=6x-12

x-6x-2=-12

-5x-2=-12

-5x=-12+2

-5x=-10

5x=10

x=10/5

x=2

Answer:

y = 5x - 6

Step-by-step explanation:

y - 9 = 5 ( x - 3 )

y = 5x - 15 + 9

y = 5x - 6

Answer:

one solution = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+17=4(3x−1)

Step 1: Simplify both sides of the equation.

5x+17=4(3x−1)

5x+17=(4)(3x)+(4)(−1)(Distribute)

5x+17=12x+−4

5x+17=12x−4

Step 2: Subtract 12x from both sides.

5x+17−12x=12x−4−12x

−7x+17=−4

Step 3: Subtract 17 from both sides.

−7x+17−17=−4−17

−7x=−21

Step 4: Divide both sides by -7

-7x/-7 = -21/-7 = 3

Answer: 130 ft^2

Step-by-step explanation:

Area= 2(wl+hl+hw)

Area= 2(5•10+1•10+1•5)

Area= 2(50+10+5)

Area= 2(65)

Area= 130

Answer:

The surface area is 130 square feet.

Step-by-step explanation:

A = 2(wl + hl + hw)

2 · (5 · 10 + 1 · 10 + 1 · 5)

Answer:

[tex]2 \frac{2}{7}[/tex] pounds, D

Step-by-step explanation:

1 pound of apples = 1.75 dollars.

Set the number of pounds of apples as x.

Then, we can write this equation.

1.75x = 4

[tex]\frac{7}{4}[/tex]x = 4

Divide both sides by [tex]\frac{7}{4}[/tex]

x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]

x = [tex]\frac{16}{7}[/tex]

x = [tex]2 \frac{2}{7}[/tex]

Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds

Step-by-step explanation:

Answer: 19 years

Step-by-step explanation:

Given

Amount invested [tex]\$400[/tex]

Rate of interest [tex]R=6\%[/tex]

after 1-year amount becomes

[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]

After n years it is

[tex]A=400\left (1.06\right)^n[/tex]

Sum accumulated is [tex]\$1200[/tex]

[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]

Answer:

[tex]\cos(W) = \frac{9}{41}[/tex]

Step-by-step explanation:

Given

[tex]\angle Y = 90^o[/tex]

[tex]YX = 40; XW = 41; WY = 9[/tex]

Required

Determine [tex]\cos(W)[/tex]

The question is illustrated with the attached image.

So:

[tex]\cos(W) = \frac{Adajacent}{Hypotenuse}[/tex]

[tex]\cos(W) = \frac{WY}{XW}[/tex]

This gives:

[tex]\cos(W) = \frac{9}{41}[/tex]

Answer:12/77

Step-by-step explanation:

The probability that a seventh grader chosen at random will play an instrument other than the Guitar is 0.76.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

The total event for seventh grade is given as,

Total = 9 + 9 + 11 + 9

Total = 38

The probability that a seventh grader chosen at random will play an instrument other than the Guitar is calculated as,

P = 9/38 + 11/38 + 9/38

P = 29/38

P = 0.76

Answer:

Step-by-step explanation:

Given,

Parallel sides of the trapezium = 50m, 90m

Height of the trapezium = 32m

Therefore,

Area of the trapezium

[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \: \times \: height[/tex]

[tex] = \frac{1}{2} \times (50 + 90)m \times 32m[/tex]

= (50 + 90) m × 16m

= 140m × 16m

[tex] = 2240 {m}^{2} (ans)[/tex]

Answer:

A = 2240 m²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex]  h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 32 , b₁ = 90 and b₂ = 50 , then

A = [tex]\frac{1}{2}[/tex] × 32 × (90 + 50) = 16 × 140 = 2240 m²

Answer:

D.

Step-by-step explanation:

its a right triangle, so we can use the pythagorean theorem to find h

(pythagorean theorem is a^2+b^2=c^2, c is the hypotenuse)

h^2+4^2=13^2

h^2+16=169

h^2=153

h=sqrt153

h≈ 12.4ft

The net below represents a container. What solid figure does it show?

We can see that the given net has 12 edges, 6 faces and 8 vertices if we compile it up. These number of edges, faces and vertices are found in a cuboid or a rectangular prism. With this we can conclude that if we compile the given net, it will form a cuboid or a rectangular prism. So, the given net is of a cuboid or a rectangular prism.
