X=60

Step-by-step explanation:

y=kx

5=15k

k=1/3

y=1/3 x

20=1/3 x

x=60

Answer:

Let us consider B’s age = X

Then A’s age = 4X

Five years ago

⇒ A’s age = 4X + 5

⇒ B’s age = X + 5

Five years hence

⇒ A’s age = 4X + 5 + 5

⇒ A’s age = 4X + 10

⇒ B’s age = X + 5 + 5

⇒ B’s age = X + 10

From the given question

4X + 10 = 2(X + 10)

4X + 10 = 2X + 20

4X – 2X = 10

2X = 10

X = 5

A’s age = 4X + 5

A’s age = 25 years

B’s age = X + 5

B’s age = 10 years

Answer:

ST = 23

RU = 8

SV = 5

SV = 10

Step-by-step explanation:

Use the knowledge of the properties of a kite to find the measure of ST, RU, SV, and SU as shown below:

✍️Recall: Each pair of adjacent sides of a kite are congruent/equal.

ST and TU are a pair of adjacent sides.

TU = 23

✅Therefore, ST = 23.

RU and RS are a pair of adjacent sides.

RS = 8

✅Therefore, RU = 8.

✍️ Recall: the longer diagonal of a kite bisects the shorter one. This means RT divides SU into two equal parts, namely SV and UV.

Since UV = 5, therefore,

✅SV = 5

SU = UV + SV

✅SV = 5 + 5 = 10

A bisector divides the lines it bisects into equal segments

The measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively

From the diagram, we have:

[tex]\mathbf{TU = 23}[/tex]

[tex]\mathbf{UV = 5}[/tex]

[tex]\mathbf{RS = 8}[/tex]

Because RT bisects SU, then:

[tex]\mathbf{ST = TU}[/tex]

So, we have:

[tex]\mathbf{ST = 23}[/tex]

Also, we have:

[tex]\mathbf{RU = RS}[/tex]

So, we have:

[tex]\mathbf{RU = 8}[/tex]

Also, we have:

[tex]\mathbf{SV =VU \times 2}[/tex]

[tex]\mathbf{SV =5 \times 2}[/tex]

[tex]\mathbf{SV =10}[/tex]

Lastly, we have:

[tex]\mathbf{SU =VU}[/tex]

[tex]\mathbf{SU =5}[/tex]

Hence, the measures of ST, RU, SV, SU are 23, 8, 10 and 5 respectively

Answer:

Step-by-step explanation:

A

The measure of SP is 80°, therefore, option (B) is correct.

The center angle that creates the intercepted arc is what is known as the arc measure, which is measured in degrees.

Given that, mKN= 20° and m∠T = 30°.

The formula for the measure of angle ∠T is:

[tex]m\angle{T}= \frac{mSP - mKN}{2}\\30^{\circ} = \frac{mSP - 20^{\circ}}{2}[/tex]

60° = mSP - 20°

mSP = 60° + 20°

mSP = 80°

Hence, the measure of SP is 80°, therefore, option (B) is correct.

Answer:

785.398 ft

Step-by-step explanation:

Circumfrence = pi * diameter

Answer:

75.39 ft

Step-by-step explanation:

r = Radius of the circle drawn by the propeller = 4 ft

Circumference of the circle is

[tex]C=2\pi r\\\Rightarrow C=2\pi 4\\\Rightarrow C=25.13\ \text{ft}[/tex]

So in one rotation the distance traveled by an ant sitting on the blade tip is 25.13 ft.

Now the ant held on for 3 rotations so distance traveled is

[tex]3\times 25.13=75.39\ \text{ft}[/tex]

The bug traveled 75.39 ft.

Answer:

A) Debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.

B) Debe agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.

C) Debe agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.

D) Debe agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.

Step-by-step explanation:

A) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 27 centímetros cúbicos para obtener un decímetro cúbico es:

[tex]x = 1000\,cm^{3}-27\,cm^{3}[/tex]

[tex]x = 973\,cm^{3}[/tex]

Por tanto, debe agregarse 973 centímetros cúbicos para obtener un decímetro cúbico.

B) Sabemos que un decímetro cúbico equivale a 1000 centímetros cúbicos, entonces la cantidad a adicionar a los 300 centímetros cúbicos para obtener un decímetro cúbico es:

[tex]x = 1000\,cm^{3}-300\,cm^{3}[/tex]

[tex]x = 700\,cm^{3}[/tex]

Por tanto, deben agregarse 700 centímetros cúbicos para obtener un decímetro cúbico.

C) Sabemos que 0,0001 metros cúbicos equivalen a 0,1 decímetros cúbicos, entonces la cantidad a adicionar a 0,1 decímetos para obtener un decímetro cúbico es:

[tex]x = 1\,dm^{3}-0.1\,dm^{3}[/tex]

[tex]x = 0.9\,dm^{3}[/tex]

Por tanto, deben agregarse 0,0009 decímetros cúbicos para obtener un decímetro cúbico.

D) Sabemos que 1 decímetro cúbico equivale a 1000000 milímetros cúbicos, entonces la cantidad a adicionar 12 milímetros cúbicos es:

[tex]x = 1000000\,mm^{3}-12\,mm^{3}[/tex]

[tex]x = 999988\,mm^{3}[/tex]

Por tanto, deben agregarse 999988 milímetros cúbicos para obtener un decímetro cúbico.

Answer:

135 ft²

Step-by-step explanation:

The profile is composed of a triangle and a rectangle.

Area of profile = (area of triangle) + (area of rectangle)

= (½×base×height) + (length × width)

Where,

base of triangle = 15 ft

height of triangle = 11 - 7 = 4 ft

length of rectangle = 15 ft

width of rectangle = 7 ft

Plug in the values

Area of profile = = (½×15×4) + (15×7)

= 30 + 105

Area of profile = 135 ft²

Answer: 18
