Lemon Squash                  If you put 90ml of concentrate in a glass, how

2 parts concentrate          water should be added?

to 5 parts water                 x  ml.

Ratio:  2:5 or 2/5

Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

2/5 = 90/x ( x = the unit (ml)/ how many ml of water)

Cross multiplication of the above equation will give us:

2x = 90 x 5 = 450

Dividing both sides by 2 we will get:

x = 450/2 = 225

Therefore, if we put 90ml of concentrate in a glass, the amont of water to be added is 225ml.

I hope this answer helps!

Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The expression is given to you is,

[tex]f(w)= 5(w+4)[/tex]

Now, if we solve the expression it can be written as,

[tex]f(w)=5w+20[/tex]

substituting the value of w, we will get,

[tex]f(9)=5(9)+20[/tex]

Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.

Answer:

x+5

Step-by-step explanation:

Hope this helps

Hi! I hope you're enjoying your day!

The linear relationship between x and y is

y=x+5

So we take a number x, add 5 to it, and that is equal to y.

Let's try and see if it works.

Let's take 2.

Add 5:

y=5+2

That should be equal to 7.

y=7

Yeah! It worked :)

Let's try another one.

Let's take 3.

y=3+5

y=8

Woo-hoo! It worked again :)

Hence, the answer is

[tex]\boxed{\boxed{\bold{Option~B~-y=x+5}}}[/tex]

Hope everything is clear.

Using proportions, it is found that the sales tax is of 8%.

A proportion is a fraction of a total amount.

In this problem, he buys a shirt for $32.00, then the second at 35% off, hence the price of the second shirt is:

P = (1 - 0.35) x 200 = 0.65 x 20 = $13.

The total price of the shirts is:

T = $32.00 + $13.00 = $45.00.

Hence, he pays $3.60 in taxes, and the sales tax is given by:

Tax = (3.6/45) x 100% = 8%.

Answer:

[tex]x^{2} < 1[/tex]

Step-by-step explanation:

Answer:

Domain:— [ x ≥ -2, x ≤ -3 ]

Range:— [ y ≥ 0 ]

Step-by-step explanation:

You may use graphing calculator to draw a graph and examine the graph’s domain and range. However, I’ll explain further about the graph of quadratic in a surd.

First, factor the quadratic expression in the surd:—

[tex]\displaystyle \large{f(x)=\sqrt{(x+3)(x+2)}}[/tex]

We can find the x-intercepts by letting f(x) = 0.

I’ll be separating in two parts — one for finding x-intercept and one for finding y-intercept.

__________________________________________________________

Finding x-intercepts

Let f(x) = 0.

[tex]\displaystyle \large{0=\sqrt{(x+3)(x+2)}}[/tex]

Solve for x, square both sides:—

[tex]\displaystyle \large{0^2 = (\sqrt{(x+3)(x+2)})^2}\\\displaystyle \large{0=(x+3)(x+2)}[/tex]

Simply solve a quadratic equation:—

[tex]\displaystyle \large{x=-3,-2}[/tex]

Therefore, x-intercepts are:—

[tex]\displaystyle \large{\boxed{x=-3,-2}}[/tex]

__________________________________________________________

Finding y-intercept

Let x = 0.

[tex]\displaystyle \large{f(x)=\sqrt{(0+3)(0+2)}}\\\displaystyle \large{f(x)=\sqrt{3 \cdot 2}}\\\displaystyle \large{f(x)=\sqrt{6}}[/tex]

Therefore, y-intercept is:—

[tex]\displaystyle \large{\boxed{\sqrt{6}}}[/tex]

__________________________________________________________

However, I want you to focus on x-intercepts instead. We know that the square root only gives you a positive value. That means the range of function can only be y ≥ 0.

For domain, first, we have to know how or what the graph looks like. You can input the function in a graphing calculator as you’ll see that when x ≥ -2, the graph heads to the right while/when x ≤ -3, the graph heads to the left. This means that the lesser value of x-intercept gets left and more value get right.

See, between -3 < x < -2, there is no curve, point or anything between the interval. Therefore, -3 < x < -2 does not exist in function.

Hence, the domain is:—

x ≥ -2, x ≤ -3

Answer:

  (h)  ST, ∠S, ∠R

Step-by-step explanation:

In general the Law of Sines is applicable when you have two angles and a side. The solution of the triangle will be unique if the given side is opposite the largest angle.

These conditions are met in choice h.

  x/sin(S) = ST/sin(R)

  x = sin(S)·ST/sin(R) = sin(34°)·7/sin(92°)

  x ≈ 3.917

__

Additional comment

Here's why the other choices don't work.

  (f) These values would require sin(R) = 15.3/8.1×sin(38°) ≈ 1.163. No angle has a sine of this value, so no triangle can be formed with these values.

  (g) The given angle is between the given sides, so the Law of Cosines is needed for solving the triangle.

  (j) Three angles are given, but no sides are given. The lengths of the sides, including x, cannot be determined.

The percentage of actual yield is 60.66%.

The percentage of a number is the hundredth part of that number.

Given that the total yield is 872.7 grams and the actual yield is 529.4 grams.

The percentage is calculated by the formula given below.

[tex]Percentage\; of\; Yield = \dfrac {Actual \;Yield }{ Total\; Yield}\times 100[/tex]

Substituting the values, we get the percentage,

[tex]Yield \;\% = \dfrac {529.4}{872.7}\times 100[/tex]

[tex]Yeils\;\%=60.66\;\%[/tex]

Hence we can conclude that the percentage of actual yield is 60.66%.
