Feels impossible to be honest. I have no idea.

First off, we can see already that there are congruent symbols in the diagram (the single and double red lines correspond to the other one that looks alike to it)

Measure QRS is like measure QPT and since QRS = 84°, then QPT also equals 84°

Measure TSR is like measure STP and since TSR = 121°, then STP also equals 121°

The value of x is 63.435, which is 60 round to the nearest tenth of a degree.

Given:

Height = 40 feet.

Distance =20 feet.

To find the value of x.

sinθ = hypotenuse/opposite.

cosθ =  hypotenuse/adjacent.

tan θ = opposite/adjacent.

tan θ = 40/20 = 2

θ = tan ⁻(2) = 63.435

Therefore, 60 for x round to the nearest tenth of a degree.

Answer: 315.45 m^2

Step-by-step explanation:

We know that the area of a circle is written as:

A = pi*R^2

Where:

pi = 3.14

R = radius of the circle.

In this case, we know that SR (the diameter) is equal to 26m

And the radius is half of the diameter, then:

R = 26m/2 = 13m

Now, in the image we can see that we have half of the circle shaded, the area of that part will be equal to half the area of a complete circle, then the area of that part is:

A = (1/2)*3.14*(13m)^2 = 265.33 m^2

We also can see that we have a small arc shaded.

The area of a given arc of an angle θ, is given by:

A = (pi*R^2)*(θ/360°)

Now we want to find the angle of this arc, that is the angle:

∠PQ

We know that:

∠SR = 180°   (this is a straight line)

∠RQ = 73°

and i assume that:

∠PS = 73°

if we look at the image, we can see that we must have:

∠QR + ∠PQ + ∠SP = ∠SR

73° + ∠PQ  + 73° = 180°

∠PQ = 180° - 2*73° = 34°

Then the area of the small arc is:

A' = (3.14*(13m)^2)*(34°/360°) = 50.12 m^2

The total shaded area is equal to the sum of the two areas we calculated, this is:

Total area = A + A' = 265.33 m^2 + 50.12 m^2 = 315.45 m^2

Answer:

$1,636,363.64

Step-by-step explanation:

let x = total amount of money received

the total amount he received is 100%

Percent remaining after giving a percent of the money to family = 100% - 20% - 25% = 55%

This means that 55% of x = $900,000

To find the value of x, divide both sides by 55% or 0.55

x = $900,000 / 0.55 = $1,636,363.64

Answer:

[tex]\frac{1}{81}[/tex]

Step-by-step explanation:

Key skills: Exponents + Fractions

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as [tex]\frac{1}{3^{4}}[/tex]

3^4 is 81, so your answer would be 1/81.

Answer:

50m

Step-by-step explanation:

Calculation for the height of the building

First step:

Let x represent the building height

Second step:

100m/8m = x/4

Third step is to Cross multiply:

100m(4) = 8x

400m= 8x

x=400m/8

x=50m

Therefore the height of the building will be 50m

It’s a Rational number

Answer:

Selling price= $580

Step-by-step explanation:

eGiving the following information:

Buying price= $400

Mark-up percentage= 45% = 0.45

The manager applies a mark-up equivalent to 45% of the buying price. First, we need to determine how much is 45% of the cost.

Mark-up= buying price* Mark-up percentage

Mark-up= 400*0.45

Mark-up= $180

Now, the selling price:

Selling price= 400 + 180

Selling price= $580

Answer:

Yes, the cost y in dollars and the amount of yogurt  are proportional.

The equation is: y = 0.08x

Step-by-step explanation:

1. If y varies directly as x, you can write it as following: y = kx

Where k is the constant of proportionality.

2. Let's calculate the value of the constant of proportionality. If y = 2.56 and x = 32, you have:

y = kx

k = y/x

k = 2.56/32

k = 0.08

3. Then, the equation is: y = 0.08

4. Let's verify if they are directly proportional. Substitute  which is the amount of yogurt bought by Jonah. The result must be $0,48:

y = 0.08 (6)

y = 0.48

5. They are directly proportional.

Answer:

38.22

Step-by-step explanation:

Remark

You take the discount first. Most places apply a sales tax only when money changes hands (or it should be that way).

Discount

45.50 * 20/100 = 9.10

45.50 - 9.10 = 36.4

Sales Tax

46.4 * 5/100 = 1.82

Total Cost

Total Cost after the discount = 36.4 + 1.82 = 38.22

Answer:

x = -8

Step-by-step explanation:

[tex]y =x[/tex]

If y = -8 — Substitute y = -8 in the equation.

[tex] - 8 = x[/tex]

Therefore, our x is -8 when y = -8

Answer:

x=-8

Step-by-step explanation:

Let's solve your system by substitution.

y=x; y=−8

Rewrite equations:

y=−8; y=x

Step: Solve y=−8 for y:

y=−8

Step: Substitute −8 for y in y=x:

y=x

−8=x

−8+−x=x+−x(Add -x to both sides)

−x−8=0

−x−8+8=0+8(Add 8 to both sides)

−x=8

-x/-1 = 8/-1

x=-8
