Answer:
216 milliliters
Step-by-step explanation:
Since, there are 3 milliliters of compound A used for every 4 milliliters of compound B.
Therefore,
A : B = 3 : 4
Let the common multiplier of the given ratios be x.
So, A = 3x & B = 4x
Since, chemist wants to make 378 milliliters of the drug.
Therefore, total volume of drug = 378 milliliters.
3x + 4x = 378
7x = 378
x = 378/7
x = 54
4x = 4*54 = 216
Thus, 216 milliliters of compound B are needed.
A cylindrical cup is 8 centimeters in height. When filled to the very top, it holds 480 cubic centimeters of water. What is the radius of the cup, rounded to the nearest tenth? Explain or show your reasoning.
Answer:
4.4cm
Step-by-step explanation:
The area of a circle is [tex]\pi r^{2}[/tex], where r is the radius.
Hence the volume of the cylinder would be [tex]\pi r^{2}h[/tex], where r is the radius and h is the height of the cylinder.
We can set up an equation V = [tex]\pi r^{2}h[/tex]
If we plug in the values we know, V=480, h=8, then we get [tex]480=8\pi r^{2}[/tex]
If we divide both sides be 8pi and square root both sides after that, we can find the value of r.
[tex]r = \sqrt{\frac{480}{8\pi } } =4.37019[/tex]
To the nearest tenth, the radius would round up, yielding 4.4cm

f(x)=x^2+2x-6 and g(x)=x+5
Type the composition (gof)(x) of the given functions
F ( x + 5 )= x ^2 + 12 x + 29
The composition (gof)(x) of the given functions is (g°f)(x) = x² + 12 x + 29
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
For two given functions f(x) and g(x), the composite function
(g ° f)(x) is g(f(x))
we know that:
g(x) = x+5
f(x) = x² + 2x - 6
Then:
(g°f)(x) = g(f(x))
So, we just need to evaluate g(x) in f(x):
g(f(x)) = f(x) + 5 = (x² + 2x - 6) + 5
(g°f)(x) = x² + 12 x + 29
Then the correct answer is (g°f)(x) = x² + 12 x + 29

I need help in question 14
Answer:
Step-by-step explanation:
Amount she gets in a day = number of flower * cost of each flower
= (25x² +5x + 5)*5x
= 25x²*5x + 5x *5x + 5*5x
= 125x³ + 25x² + 25x
Amount she gets in 5 day = (125x³ +25x² + 25x)* 5
= 125x³*5 + 25x² *5 + 25x *5
= 625x³ + 125x² + 125x

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that are on sale for $10 each, including tax.
Answer:
5 video games.
Step-by-step explanation:
In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.
120 - 68 = 52
Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.
52 / 10 = 5.2
Finally, we can see that she can afford to only buy 5 video games.

what of the following us a solution to the system of equations
Answer:
(- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 2 → (1)
6 + y = - x → (2)
Substitute y = 3x - 2 into (2)
6 + 3x - 2 = - x
4 + 3x = - x ( add x to both sides )
4 + 4x = 0 ( subtract 4 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 3(- 1) - 2 = - 3 - 2 = - 5
solution is (- 1, - 5 )

9x = 27 + 18
9x = 45
x = 45/9
x = 5

Hiya please leave formulas x
Answer:
angle c = 107°
angle b = 107°
angle a = 73°
Step-by-step explanation:
Given:
Two line XY and WZ intersect each other and make four angle [a, b, c, d]
Given that Angle d = 73°
Find:
angle a
angle b
angle c
Computation:
We know that angle c and angle d situated on same line XY
So,
angle c + angle d = 180°
angle c + 73° = 180°
angle c = 107°
We know that angle b and angle d situated on same line WZ
So,
angle b + angle d = 180°
angle b + 73° = 180°
angle b = 107°
angle a and angle d are vertical opposite angle
So,
angle a = angle d
angle a = 73°

Dos libras de carne de res y dos de chivo cuestan $334 pesos, si duplico la libra de carne de res y una libra de chivo cuestan $420 pesos. ¿Cuál es el precio por libra de cada producto?
Answer:
El precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
Step-by-step explanation:
Con la información proporcionada puedes escribir las siguientes ecuaciones:
2x+2y=334 (1)
4x+y=420 (2), donde:
x es el precio por libra de carne de res
y es el precio por libra de chivo
Primero, puedes despejar x en (1):
2x=334-2y
x=334/2-2y/2
x=167-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
4(167-y)+y=420
668-4y+y=420
668-3y=420
668-420=3y
248=3y
y=248/3
y=82.67
Finalmente, puedes reemplazar el valor de y en (3) para encontrar el valor de x:
x=167-y
x=167-82.67
x=84.33
De acuerdo a esto, la respuesta es que el precio por libra de la carne de res es $84.33 y el precio por libra de chivo es $82.67.
The width of a box is two-third of its length and height is
one-third of its length. If the volume of the box is 1296 m3,
ind the area of base of the box.
Answer:
216m² is your answer
Step-by-step explanation:
given
width [b]=2/3 ×l
length [l]=l
height [h]=1/3 l
we have
volume of cuboid =l×b×h
1296m³=l×2/3×l×1/3×l
1296m³=2/9×l³
l³=1296×9/2=5832
l³=18³
length [l]=18m
breadth [b]=2/3×18=12m
area of base of box =l×b=18×12=216m²

A circular fountain has a drain in the center. The distance from the drain to the edge of the fountain is 3 feet. What is the circumference of the fountain? Round your answer to the nearest tenth of a foot.
Answer:
18.8 feet
Step-by-step explanation:
Since the drain is in the center, the distance between the drain and the edge is the radius of the circular fountain.
Use the circumference formula: C = 2[tex]\pi[/tex]r, and plug in 3 as r (the radius).
C = 2[tex]\pi[/tex]r
C = 2[tex]\pi[/tex](3)
Solve for C:
C = 6[tex]\pi[/tex]
C = 18.8
So, the circumference of the fountain is approximately 18.8 feet
