Answer:

B. 6.4

Step-by-step explanation:

We need to recall the theory of  the chord distance to the center which tells that the two congruent chords are equidistant from the center of the circle.

In this situation, A is the center point, CR and  BE are congruent with the length of 5,27. So, the distance from A to CR must be equal to the distance from A to BE. Hence, the length of the blue segment in A below is 6.4

Answer:

There are 60t liters of water in the bathtub after t minutes.

After t minutes, [tex]\( 60t \)[/tex] liters of water fill the bathtub.

The amount of water in the bathtub after t minutes can be expressed as the product of the rate of filling (60 liters per minute) and the time (t minutes):

[tex]\[ \text{Amount of water} = \text{Rate of filling} \times \text{Time} \][/tex]

[tex]\[ \text{Amount of water} = 60 \text{ liters/minute} \times t \text{ minutes} \][/tex]

[tex]\[ \text{Amount of water} = 60t \text{ liters} \][/tex]

Step-by-step explanation:

In a Right angled triangle , if a, b are the sides and h be the hypotenuse then relationship between them is given by

[tex]h^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

Here,

         a= 4 in.        [Given]

          b = 6 in.       [Given]

Thus ,

  [tex]h^{2}[/tex]  = [tex]4^{2}[/tex] + [tex]6^{2}[/tex]

  [tex]h^{2}[/tex]  =  16 + 36

  [tex]h^{2}[/tex]  = 52.

   h = [tex]\sqrt{52}[/tex]  = 7.21110255......

To drain the water tower it will take 36 hours.

Step-by-step explanation:

Given:

A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.

Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.

Gallons of total water in the tower ÷ Gallons of water drained per hour

[tex]72000\div 2000[/tex]

Answer:

Option B.

Step-by-step explanation:

It is given that the sides of an equilateral triangle are 8 units long.

Draw an altitude of the triangle.

Altitude of an equilateral triangle is perpendicular bisector.

Let x be the length of the altitude of the triangle.

According to the Pythagoras theorem

[tex]hypotenuse^2=base^2+perpendicular^2[/tex]

Using Pythagoras theorem we get

[tex]8^2=4^2+x^2[/tex]

[tex]64=16+x^2[/tex]

[tex]64-16=x^2[/tex]

[tex]48=x^2[/tex]

Taking square root on both sides.

[tex]\sqrt{48}=x[/tex]

[tex]4\sqrt{3}=x[/tex]

The length of the altitude of the triangle is 4√3 units.

Therefore, the correct option is B.

Answer:

The base is 11 inches long

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

Let

y -----> is the length of the base of the isosceles triangle

x ----> is the length of each of the congruent sides

The perimeter of the triangle is equal to

[tex]P=y+x+x[/tex]

[tex]P=y+2x[/tex]

we have

[tex]P=55\ in[/tex]

so

[tex]55=y+2x[/tex] ----> equation A

[tex]y=\frac{x}{2}[/tex] ----> equation B

solve the system by substitution

substitute equation B in equation A

[tex]55=\frac{x}{2}+2x[/tex]

solve for x

[tex]55=\frac{5}{2}x[/tex]

[tex]x=55(2)/5\\x=22\ in[/tex]

Find the value of y

[tex]y=\frac{x}{2}[/tex] ----> [tex]y=\frac{22}{2}=11\ in[/tex]

therefore

The base is 11 inches long

Answer:

Yeah I'm here harmony plz tell

Step-by-step explanation:

Note that this is the equation of a line, since you can rewrite it as

[tex]3x-4y=6 \iff 4y=3x-6 \iff y=\dfrac{3}{4}x-\dfrac{3}{2}[/tex]

Now just choose two values for x and compute the correspondent y values:

[tex]x=0 \implies y=-\dfrac{3}{2}[/tex]

So, the line passes through the point (0, -3/2).

[tex]x=2 \implies y=\dfrac{3}{2}-\dfrac{3}{2}=0[/tex]

So, the line passes through the point (2, 0)

Now, draw on a coordinate plane the two points and connect them, and you'll have the line.

a = -3 is a Solution to the equation 4a + 3 = -9  

Step-by-step explanation:

Given:

a = -3

4a + 3 = -9

Proof for Solution:

Let there be two part of the equation, left-hand side and right hand side.

If a  = -3 is a solution ,

left-hand side = right hand side

left-hand side = 4a +3

                       = 4×-3 + 3...............{ For a = -3}

                       = -12 + 3

                       = -9

                       = right hand side

∴ left-hand side = right hand side

∴ a = -3 is a Solution to the equation 4a + 3 = -9  

The central angle created by an arc length of 6.9813 in a circle with a radius of 4 is approximately 100 degrees when rounded to the nearest whole number.

The student is asking about the relationship between the arc length of a circle, the radius of the circle, and the central angle created by this arc. To find the central angle from the arc length and the radius, we use the formula:

arc length (As) = radius (r) x central angle (θ)

Here, we're given the arc length as 6.9813 and the radius as 4. Since the central angle is usually given in radians, we first perform the calculation in radians and then convert it to degrees if necessary.

The central angle in radians is:

θ (in radians) = arc length / radius

θ = 6.9813 / 4 ≈ 1.7453 radians

To convert radians to degrees, we multiply by,

(180/π).

Thus,

θ (in degrees) ≈ 1.7453 x (180/π) ≈ 100 degrees

And when rounded to the nearest whole number:

θ ≈ 100 degrees

So, the central angle created by the arc is approximately 100 degrees.

Given as :

The expression is written

( [tex]\dfrac{-11 }{2}[/tex]x + 3 ) - 2 ( - [tex]\dfrac{11 }{4}[/tex]x - [tex]\dfrac{5 }{2}[/tex])

Or, ( [tex]\dfrac{-11 }{2}[/tex]x + 3 ) +[tex]\frac{11\times 2}{4}[/tex]x+  [tex]\frac{5\times 2}{2}[/tex]

Now, separate the variable terms

Or, ( [tex]\dfrac{-11 }{2}[/tex] + [tex]\frac{11\times 2}{4}[/tex]) x +  3 + 5

Or, ( 0) × x + 8

or , 0 + 8

∴ 8    

The simplest form if expression is 8

Hence The solution of expression in the simplest form is 8 . Answer

The solutions of the system of equations are (0 , -6) , (-1 , -8)

Step-by-step explanation:

To solve a system of equations, one 1st degree and the other 2nd degree, do that:

∵ The system of equations is:

y = x² + 3x - 6 ⇒ (1)

y = 2x - 6 ⇒ (2)

Equate (1) and (2)

∴ x² + 3x - 6 = 2x - 6

- Add 6 to both sides

∴ x² + 3x = 2x

- Subtract 2x from both sides

∴ x² + x = 0

- Take x as a common factor in the left hand side

∴ x(x + 1) = 0

- Equate each factor by 0 to find the values of x

∵ x = 0

∴ The first value of x is 0

∵ x + 1 = 0

- Subtract 1 from each side

∴ x = -1

∴ The second value of x is -1

Substitute each value of x in equation (2) to find the values of y

∵ y = 2(0) - 6

∴ y = 0 - 6 = -6

The first value of y is -6

∵ y = 2(-1) - 6

∴ y = -2 - 6 = -8

∴ The second value of y is -8

∴ The solutions are (0 , -6) , (-1 , -8)

The solutions of the system of equations are (0 , -6) , (-1 , -8)

   m = 5

{b} 5 lb peanuts and 5 lb mixture

Step-by-step explanation:

m1 → desired mixture with composition : 60% peanuts and 40% almonds and weight : 10 lb

⇒weight of peanuts in m1 = 60% × 5 = 6 lb

and weight of almonds in m1 is 4 lb

m2 → mixture with composition : 20% peanuts and 80% almonds and weight : m pounds

⇒weight of peanuts in m2 = 0.2m

and weight of almonds in m2 = 0.8m

p → weight (in pounds) of peanuts added to m2 to make m1

{a}

add p pounds of peanuts to m2 to make m1

equating weights of peanuts and almonds:

p + 0.2m = 6

0.8m = 4

{b}

equation gives m = [tex]\frac{4}{0.8}[/tex] ⇒ m = 5 lb

Using this in the [tex]1^{st}[/tex] equation:

p + 1 = 6 ⇒ p = 5 lb

Answer:

a) p + m = 10 and [tex]\frac{p + 0.2m}{0.8m} = \frac{60}{40}[/tex]

b) The mixing amount is 5 lb peanut and 5 lb mixture.

Step-by-step explanation:

Given that p pounds of peanuts and m pounds of the 80% almond and 20% peanut mixture are used to make 10 pounds of 60% peanuts and 40% of almonds mixture.

Now, we can write that p + m = 10 ........ (1)  

Now, m pounds of 80% almond and 20% peanut mixture contain 0.2m pounds of peanuts and 0.8m pounds of almonds.

Now, from the condition given it can be written that  

[tex]\frac{p + 0.2m}{0.8m} = \frac{60}{40}[/tex] .......... (2)

⇒ [tex]\frac{p + 0.2m}{0.8m} = \frac{3}{2}[/tex]

⇒ 2p + 0.4m = 2.4m

⇒ 2p = 2m

⇒ p = m  

Now from equation (1) we get p = m = 5 pounds.

a) Therefore, equations (1) and (2) are the system of equations that models the situation.

b) The mixing amount is 5 lb peanut and 5 lb mixture. (Answer)
