Answer: 12.5

Step-by-step explanation:

12.5 is the length of BC.

Here, we have,

given that,

In the diagram shown below, AC is tangent to circle o at A and to circle Pat C, OP intersects AC at B, OA = 5, AB = 5, and PC = 10.

now, we know that,

∠OAB and  ∠BCP are right angles, because of the tangents.

and, ∠OBA ≅ ∠CBP (vertical angles)

thus, we get,

ΔAOB ≅ ΔCBP, by AA rule.

so, we can set up the proportion:

10/4 = x/5

or, x = 12.5

Hence, 12.5 is the length of BC.

Answer:

2, -7

Step-by-step explanation:

Solve the system of linear equations:

-------------------------------------------------------------------------------------

Add the equations together to eliminate y:

     8x = 93 + 11y

+    7x = -63 - 11y

    -------------------

    15x = 30

⇒ x = 30 ÷ 15

⇒ x = 2

Now substitute the found value of x into one of the equations and solve for y:

⇒ 7x = -63 - 11y

⇒ 7(2) = -63 - 11y

⇒ 14 = -63 - 11y

⇒ 11y = -63 - 14

⇒ 11y = -77

⇒ y = -77 ÷ 11

⇒ y = -7

Therefore, x = 2 and y = -7

Answer: 1/5 of the total distance to his grandmothers house was traveled on Sunday

The total distance to to his grandmothers house is assumed to be 1

Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would

1 - 7/10 = 3 /10

They traveled 2/3 of the remaining distance on Sunday. This means that the distance that they travelled on Sunday is

2/3 × 3/10 = 2/10 = 1/5

Answer:

sinx=5/√41

Step-by-step explanation:

tanx=5/4=p/b

According to Pythagoras's theroem;

h=√p^2+b^2

or, h=√5^2+4^2

or, h=√25+16

:-h=√41

Now,

sinx=p/h

=5/√41

Answer:

27 degrees

Step-by-step explanation:

The easy way is by remembering the formula (a-b)/2=c, where a is the larger angle, and b is the smallest angle. (90-36)/2=27.

The longer, more drawn out answer goes as follows. See the image to understand the notation I use:

Note: The long drawn out method shown above is a way to derive the formula for the secant theorem. You do not need to use this method every time. Just remember, large angle minus small angle, all divided by 2. That is it.

Answer:

q = -3.25

p = -6.25

Step-by-step explanation:

substitute p with ( q-3)

q-3 = 5(q+2)

q-3 = 5q + 10

q-5q = 3+10

-4q = 13

q = -3.25

if q = -3.25 therefore

p= -3.25 -3

= -6.25

Step-by-step explanation:

The height of the triangle will be equal to H=8.66 inches and the area of the triangle will be 43.30 square inches.

The space covered by the triangle in the two-dimensional plane will be the area of the triangle.

It is given that in the triangle all three sides are 10 inches:-

Height of the triangle=?

Area of the triangle=?

First the height of the triangle will be calculated as:-

[tex]\rm Tan\theta=\dfrac{P}{B} \\\\\\Tan\theta=\dfrac{P}{5}\\\\\\Tan60=\dfrac{P}{5}\\\\\\P=8.66\ inches[/tex]

The area of the triangle will be:-

[tex]\rm Area= \dfrac{1}{2}\times Base\times Height\\\\\\Area=\dfrac{1}{2}\times 5\times 8.66\\\\\\Area = \43.30\ square \ inches[/tex]

Hence the height of the triangle will be equal to H=8.66 inches and the area of the triangle will be 43.30 square inches.

The probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have:

Mary has 3 blouses (red, black, and white), 2 pairs of pants (black and blue), and 4 pairs of shoes (red, blue, black, and white).

P(black blouse) = 1/3

P(black pants) = 1/2

P(black shoes) = 1/4

Probability that Mary's outfit will be black blouse, black pants, black shoes:

= (1/3)(1/2)(1/4)

= 1/24

Thus, the probability that Mary's outfit will be black blouse, black pants, black shoes is 1/24 if the Mary has 3 blouses, 2 pairs of pants, and 4 pairs of shoes.

The value of y is 3 if the value of x is 4 in the linear equation with two variables.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Two linear equations in two variables x and y

x + y = 7

x = 4

Plug x = 4 in the equation x + y = 7, we get:

4 + y = 7

y = 7 - 4

y = 3

Thus, the value of y is 3 if the value of x is 4 in the linear equation with two variables.

Step-by-step explanation:

In order to solve this, we'll set up a proportion.

Since y is inversely related to the square of x, therefore:

y=4/63 ----->9 (square of x)

y=?

25 (square of x)

According to the inverse relation:

y=4/63------->25

y=? --------

Answer:

1/π²

Step-by-step explanation:

On multiplying π² by its inverse value, you get the answer to be 1, which has no decimal points.

Answer:

π² × 1/π² = 1

Step-by-step explanation:

Given equation,

→ π² × ___ = ?

Let's keep the missing term as y, and product as 1 (a number with no decimal).

→ π² × y = 1

Then the answer will be,

→ π² × y = 1

→ [ y = 1/π² ]

Verification of the value of y,

→ π² × y = 1

→ π² × (1/π²) = 1

→ [ 1 = 1 ]

→ LHS = RHS

Hence, 1/π² is the missing term that ends up with a number with no decimal.
