Architects use geometry to study and divide space as well as draft detailed building plans. Builders and engineers rely on geometric principles to create structures safely. Designers apply geometry (along with color and scale) to make the aesthetically pleasing spaces inside. Applying geometry in design is unavoidable.

By weighted average, we need 75 liters of 24 % iodine solution and 25 liters of 40 % iodine solution to obtain 100 liters of 28 % iodine solution.

Physically speaking, concentration is equal to the amount of solute divided by the volume of solution. We have two solutions with same solute and different concentration and can find the right proportion between the 24 % solution and the 40 % solution by concept of weighted average:

x · 24 + (1 - x) · 40 = 28

40 - 16 · x = 28

16 · x = 40 - 28

16 · x = 12

x = 3/4

By weighted average, we need 75 liters of 24 % iodine solution and 25 liters of 40 % iodine solution to obtain 100 liters of 28 % iodine solution.

Answer:

the measure of each angle is 75degrees

Step-by-step explanation:

The wording is slightly confusing so I will just solve the equation.

2 (y + 6) = 4y

We expand the bracket

2y + 12 = 4y

We subtract 2y from both sides

12 = 2y

We divide both sides by 2

6 = y

Step-by-step explanation:

the missing side is given by sqrt(16² - 8²)

hence,

the number that belongs in the green box is 192

Answer:

See below

Step-by-step explanation:

If the whole rectangle were shaded (all 25 parts) that would be 100%

So, we can set up a proportion.

25 = 100%

11 = x

Then, cross-multiply to get,

25x = 1100

Divide both sides by 25 to solve for x

x = 44.

The x value represents the percentage shaded.

Step-by-step explanation:

A coterminal angle of θ such that 0 ≤ θ ≤ 2π is equal to 7π/4 and the exact value of Sin(θ) = -1/√2.

A coterminal angle can be defined as an angle that share the terminal side of an angle which occupies the standard position i.e it has the same initial side.

In this scenario, all angles that are multiples of 2π and added to the given angle (-9π/4) would be coterminal. For the range [0, 2π], 8π should be added to the given angle as follows:

Coterminal angle = -9π/4 + 4π

Coterminal angle = -9π/4 + 16π/4

Coterminal angle = 7π/4.

The reference angle is given by:

7π/4 -π = 3π/4.

Therefore, the exact values of all six (6) trigonometric functions evaluated at θ are:

Answer:

a) 1/2, b) = - sqrt(3) / 2

Step-by-step explanation:

a) Let A = 120 degree, B = 180 degree

Using cosine sum is cos(120+180) = cos(120)*cos(180) - sin(120)* sin(180)

which will give you 1/2

b) Let A = 360, B = 60 degree

Using sine difference: sin(360-60) = sin(360) cos(60) - cos(360) sin (60)

gives you -sqrt(3)/2

Cos (300°) using the cosine sum identity is 1/2.

sin (300°) using the sine difference identity is √3/2.

Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.

The main three trigonometric ratios are sine, cosine and tangent functions.

Part A :

The cosine sum identity is,

cos (A + B) = cos (A) cos (B) - sin (A) sin (B)

We can write cos (300°) as,

cos (300°) = cos (180° + 120°)

                  = cos (180°) cos (120°) - sin (180°) sin (120°)

sin (180°) = 0 and cos (180°) = -1

So,  cos (300°) = -cos (120°) = -(-1/2) = 1/2

Part B :

Sine difference identity is,

Sin (A - B) = sin (A) cos (B) - cos(A) sin (B)

We can write sin (300°) as,

sin (300°) = sin (360° - 60°)

                = sin (360°) cos(60°) - cos(360°) sin (60°)

                = - sin (60°)

                = -√3 / 2

Hence the value of Cos (300°) using the cosine sum identity is 1/2 and the sin (300°) using the sine difference identity is √3/2.

The sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa are shown in the picture by the Venn diagram.

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

From a sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa, 30 took all the three beverages, 70 took coffee and cocoa, 110 took coffee only, and 185 took cocoon only.

We can represent the above data by the Venn diagram as shown in the picture.

From the Venn diagram:

The number of customers who took none of the beverages

= 800 - 580 = 220

The number of customers who took tea only = 95

The number of customers who took tea and cocoa only = 70

The number of customers who took tea and coffee only = 50

The number of customers who took none of the beverages = 220

Thus, in the sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa are shown in the picture by the Venn diagram.

Answer : 11 and 13

Step-by-step explanation:

Let the numbers be X and Y then,

By question

X= Y - 2 .....................(i)

2Y = 3X - 7 ...............(ii)

putting the value of X from (i) on equation (ii) we get,

2Y = 3(Y - 2) - 7

2Y = 3Y - 6 - 7

2Y - 3y = - 13

-Y = - 13

Y = 13

now putting value of Y in equation (i)

X = 13 - 2= 11

hence those numbers are 11 and 13 respectively

Fish fed during night  is equal to  1/6 tons

Let the weight of the fish fed at night = X tons

In the morning, the weight of the fish fed Wm = 2/15 tons.

In the afternoon, 1/15 ton more fish fed during the morning.

∴ Weight of fish fed in afternoon Wa

= 2/15 + 1/15

= 3/15 tons

Given that,

Wm + Wa + Wn = 1/2 tons

∴ 2/15 + 3/15 + Wn = 1/2

∴Wn = 1/2 - 5/15

∴ Wn = 3/6 - 2/6

Answer:

a = 4

b = 7

c = 0

4n² + 7n = 0

4/4n² + 7n/4 = 0/4

a = 1

b = 7/4

c = 0

b = 7/4

(b/2)² = (7/4 ÷ 2)²

Use fraction rule.

7/4 ÷ 2² = 7/4² / 2²

square the numbers

7/4² / 2² = 49/16 ÷ 4

49/16 ÷ 4 = 49/16 × 1/4

49/16 × 1/4 = 49/64

Add to both sides of the equation using 49/64

b = 7/4

b/2 = 7/4 ÷ 2

simplify

b/2 = 7 ÷ (4 × 2)

simplify(arithmetic)

b/2 = 7/8

n² + 7/4n + 49/64 = 49/64

Answer:

O The value of f(2) is smaller than the value of f(1).

Step-by-step explanation:

First, let's solve for both. When the problem says f(1) or f(2), this just means that the x value is equal to that. So:
f(1) = -5(1)^2 + 2(1) + 9 = 6
f(2) = -5(2)^2 + 2(2) + 9 = -7
Since f(1) = 6 and f(2) = -7, we know that f(1) is greater than f(2). Therefore, the value of f(2) is smaller than the value of f(1)
