set up the equation relating the new ratio of broth to solution to the new percentage of broth to solution. 25/60
The new percentage of broth to solution 25/60 is 41.67
Broth, also known as bouillon is a savory liquid made of water in which meat, fish or vegetables have been simmered for a short period of time .It can be eaten alone, but it is most commonly used to prepare other dishes, such as soups.
Commercially prepared liquid broths are available, typically chicken, beef, fish, and vegetable varieties. Dehydrated broth in the form of bouillon cubes were commercialized beginning in the early 20th century.
Broths have been used as a nutrition source for the sick in Great Britain since at least the early 1700s, such as for dysentery patients
Let,
60 represents the 100% of the broth to solution
25 represents the x percentage of the broth to solution
Now,
Solving for the 25 which represents the x percentage of the broth to solution.
25/100 = x/100*
25/60 = x/100*x
25(100) = 60x
x = 2500/60
x = 41.67
Therefore,
25 represents the 41.67 percentage of the broth to solution.

Answer:
x = -7
Let the first integer be x.
Given the next two integers are consecutive, it would be: x+1, x+2
The problem states: "4 more than the smaller number plus twice the 3rd number is 7 less than the 2nd number."
Translating English to Algebra, you'll get:
(x + 4) + 2(x + 2) + 7 = x + 1
x + 4 + 2x + 4 + 7 = x + 1
3x + 15 = x + 1
2x = -14
x = -7
That would be the third option.

Answer:

Step-by-step explanation:
First start by raising all the numbers to the power indicated:
5^4 = 625
8^5 = 32768
2^9 = 512
5^2 = 25
Then divide the numerators by the denominators:
625 / 8 = 78.125
32768 / 64 = 512
512 / 25 = 20.48
Finally, multiply all the numbers together
78.125 * 512 * 20.48 = 819200

The scale factor of the airplane is 200.
What is a scale factor?A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.
We have
The height of the plane in scale drawing:
= 10 cm
The height of the plane in an actual airplane.
= 20 m
The scale factor of the height of the airplane:
= 20m / 10 cm
[ 1 m = 100 cm ]
= (20 x 100) cm / 10 cm
= 200

Answer:
10 cards
Step-by-step explanation:
In order to find how many packs Joel needs to buy we need Make an equation
Equation = 5c + 15 = 65
where,
c = cards5c+15=65
Step 1: Subtract 15 from both sides.
5c+15−15=65−15
5c=50
Step 2: Divide both sides by 5.
5c/5 = 50/5

mav is older than justin. Their ages are consecutive integers find mavs age if the product of their age is 42
Answer:
7
Step-by-step explanation:
hope this works :)
consecutive numbers means 2 numbers next to eachother like 8 and 9 or 3 and 4
product means basically the result of numbers multiplying together, e.g. the product of 8×9 = 72
so if you use trial and error you will find 6 × 7 = 42 and since mav is older she must be 7 years old
Answer:
mav is 7
Step-by-step explanation:
let justin's age be n then mav is n + 1 and the product is
n(n + 1) = 42
n² + n = 42 ( subtract 42 from both sides )
n² + n - 42 = 0 ← in standard form
(n + 7)(n - 6) = 0 ← in factored form
equate both factors to zero and solve for n
n + 7 = 0 ⇒ n = - 7
n - 6 = 0 ⇒ n = 6
since n > 0 then n = 6
mav is n + 1 = 6 + 1 = 7

Answer:from least to greatest:
1) g (x)
2) f (x)
3) h (x)
Step-by-step explanation:
Answer:
For f (x):
f (x) = (x + 3) ^ 2 - 2
For x = -1
f (-1) = (-1 + 3) ^ 2 - 2
f (-1) = (2) ^ 2 - 2
f (-1) = 4 - 2
f (-1) = 2
For x = 3
f (3) = (3 + 3) ^ 2 - 2
f (3) = (6) ^ 2 - 2
f (3) = 36 - 2
f (3) = 34

m = 1/2
The function g (x) is:
g (x) = (1/2) x - 3/2
For x = -1
g (-1) = (1/2) (- 1) - 3/2
g (-1) = -1/2 - 3/2
g (-1) = -4/2
g (-1) = -2
For x = 3
g (3) = (1/2) (3) - 3/2
g (3) = 3/2 - 3/2
g (3) = 0
AVR = ((0) - (- 2)) / ((3) - (- 1))
AVR = 1/2
For h (x):
Using the table we have:

In a food court there are people eating hamburgers, burritos & pizza. P(h) = 0. 38 and P(b) = 0. 31. If there are 35 people eating pizza, what is the total number of people in the food court?
Answer should be rounded to the nearest WHOLE NUMBER
The total number of people in the food court eating pizza, burritos, and hamburgers is 113 (Approximate) or (Whole number)
People eating hamburger P(h) =0.38
People eating burritos P(b) = 0.31
Number of people eating pizza = 35
Let's suppose the total number of people is 1
So,
By adding the total number of people eating hamburgers and burritos
= 0.38+0.31
= 0.69
The ratio of the total number of people eating pizza = 1.00 - 0.69
= 0.31
So total number of people eating pizza = 0.31 = 35
By solving :
1 = 35 / 0.31
= (35*100)/31
= 3500/31
= 112.9 (we have to write it down in the nearest whole number)
Here we writing the approximate value of 112.9 = 113 (Approximate)
Hence, the total number of people in the food court in the nearest whole number is 113

write the equation for a parabola with a focus at (6,-4)(6,−4)left parenthesis, 6, comma, minus, 4, right parenthesis and a directrix at y
The equation of the parabola is (x - 6)² = 6(y + 5.5).
Given that, a focus at (6,-4) and a directrix at y= -7.
We need to find the equation for a parabola.
What are focus and directrix?Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h , k)
The focus is (h, k + p)
The directrix is at y = k - p
∵ The focus of the parabola is at (6, -4)
The coordinates of the focus are (h, k + p)
∴ h = 6
∴ k + p = -4 ⇒ (1)
∵ The directrix of the parabola is at y = -7
The directrix is at y = k - p
∴ k - p = -7 ⇒ (2)
Solve the system of equations to find k and p
Add equations (1) and (2) to eliminate p
∴ 2k = -11
Divide both sides
∴ k = -5.5
Substitute the value of k in equation (1) to find p
∵ -5.5 + p = -4
Add 5.5. to both sides
∴ p = 1.5
∵ The form of the equation is (x - h)² = 4p(y - k)
Substitute the values of h, k, and p in the form
∴ (x - 6)² = 4(1.5)(y - -5.5)
∴ (x - 6)² = 6(y + 5.5)
Therefore, the equation of the parabola is (x - 6)² = 6(y + 5.5).

If m∠j=91 m∠l=16 and m∠k=73 list the sides of ∆JLK in order from smallest to largest
Answer:
ikj
Step-by-step explanation:
In a triangle:
The shortest side is opposite the smallest angle.The longest side is opposite the biggest angle.When labeling angles and sides of triangles, it is convention to label the side opposite an angle with the same letter but in lower case.
Therefore in ∆JLK:
Side j is opposite angle J.Side l is opposite angle L.Side k is opposite angle K.As 16 < 73 < 91
⇒ m∠I < m∠K < m∠J
As the angles of ∆JLK in order from smallest to largest are IKJ, then the sides of ∆JLK in order from smallest to largest are ikj.
