Regrouping terms in the sum as

x + (-5x + 5x) + (-9x + 9x) + … + (-21x + 21x) - 25x

you can see that all the middle terms cancel and you're left with

x - 25x = -24x

Find the arc length of the subtending arc for an angle of 35 degrees on a circle of radius 10.

Answers

Step-by-step explanation:

arc length = radius × central angle in radian

= 10 × (35 × π/180)^c

= 10 × ( 7π/36)

= 70π/36

= 70/36 × 22/7

= 55/9

= 6.111cm

please!!!!! mark me as brainliest

and

i hope my ans is helpful

Answer:

formula for length of an arc = 0 / 360 × 2ūr

Given , 0 = 35 , ū = 22/7 ,r =10

therefore; 35/360 × 2 x 22/7 ×10

1) Set up, but do not solve, a system of equations for the following application: A nurse mixes a 100% saline solution with a 20% saline solution to produce 160 milliliters of a 25% saline solution. How much of the 100% saline solution and how much of the 20% saline solution were used?

Answers

The systems of the equations for the word problem can be expressed as:

x + y = 500              --- (1)100x + 20y = 4000  --- (2)

What is a system of equations?

The system of equations is a set of simultaneous equations that comprises two or more equations expressed in algebraic terms.

From the given information, we are to determine two quantities

i.e.

For 100% saline solution (x) andFor 20% saline solution  (y)

So, 100% and 20% of saline solution produce 160 millimeters.

x + y = 160

Also, the combination of 100% and 20% of saline solution give an average of 25%.

The average now = sum of numbers/ the total numbers

25% = sum of numbers/160

sum of numbers = 25% (160)

Therefore, we can equate it to the mixture carried out by the nurse.

i.e.

25% (160) = 100%(x) + 20%(y)

100x + 20y = 4000

Therefore, the systems of the equations are:

x + y = 500              --- (1)

100x + 20y = 4000  --- (2)

Find three consecutive integers such that their sum is 40 more that tiwce the middle integer.

Answers

Answer:

  39, 40, 41

Step-by-step explanation:

Let x represent the middle integer. The sum of the three integers will be ...

  (x -1) +x +(x +1) = 3x

This is 40 more than 2 times the middle integer, so we have ...

  3x = 40 +2x

  x = 40 . . . . . . . subtract 2x

The three integers are 39, 40, 41.

Additional comment

It often works well to solve consecutive integer problems by letting a variable represent the middle value, or the average of the integers.

In circle R, RS = 12 and m/SRT = 90°. Find the length of ST. Express your
answer as a fraction times 7.
R
T
S

Answers

Answer:

[tex]l(\widehat {ST})=6\pi [/tex]

Step-by-step explanation:

Radius (r)= RS = 12 (Given)

[tex] Central\: angle \:(\theta) = m\angle SRT =90\degree[/tex] (Given)

To find: [tex]l(\widehat {ST})[/tex]

Formula for finding the length of arc is given as:

[tex]l(\widehat {ST})=\frac{\theta}{360\degree}\times 2\pi r[/tex]

[tex]l(\widehat {ST})=\frac{90\degree}{360\degree}\times 2\pi (12)[/tex]

[tex]l(\widehat {ST})=\frac{1}{4}\times 24\pi [/tex]

[tex]l(\widehat {ST})=6\pi [/tex]

The required length of an arc ST is 6π units which is subtended by an angle.

What is an arc?

The arc is a portion of the circumference of a circle.

The formula for calculating the arc states that:

Arc length = 2πr (θ/360)

Where r = the radius of the circle,

θ = the angle (in degrees) subtended by an arc at the center of the circle.

As per the question, we have:

θ = 90° and r = 12 units

Substitute the given values in the formula,

Arc length = 2π(12) (90/360)

Arc length = 6π

Therefore, the required length of an arc ST is 6π units.

Answers

Contain B holds 750 mL and container A holds 350 mL. Then contain B holds more amount than container A.

What is conversion?

Conversion means to convert the same thing into different units.

Let container A contains 350 milliliters.

Let container B contains 0.75 liters.

The conversion of liters to milliliters will be given below.

1 liter = 1000 milliliters

Then we have

Container A = 350 mL

Container B = 0.75 x 1000 = 750 mL

Then the contain B holds 750 mL and the container A holds 350 mL.

Then contain B holds more amount than container A.

1) Finding the tan of ∠BAC

[tex]tan(\theta)=\dfrac{4}{5}[/tex]

[tex]\theta=tan^-1(\dfrac{4}{5})[/tex]

2) Finding the tan of ∠CAD

[tex]tan(\theta)=\dfrac{3}{6}[/tex]

[tex]\theta=tan^-1(\dfrac{3}{6})[/tex]

3) Add the value of ∠BAC to the value of ∠CAD

[tex]tan^-1(\dfrac{4}{5})+tan^-1(\dfrac{3}{6})≈65.22°[/tex]

4) The sum of interior angles in quadrilateral is 360°

Then

[tex]tan(∠BAC)+tan(∠ACB)+tan(∠CAD)+tan(∠ACD)=360°[/tex]

[tex]tan^-1(\dfrac{4}{5})+tan^-1(\dfrac{5}{4})+tan^-1(\dfrac{3}{6})+tan^-1(\dfrac{6}{3})=180°[/tex]

[tex]180°+∠CDA+∠CBA=^?360[/tex]

5. A sum of money is divided among Ethan, Jun Wei

Find the amount of money Ethan has after giving
to his mother, the ratio becomes 3:4:6.
$50 to his mother.
(Step by step explain pls)

Answers

Answer:

$450

Step-by-step explanation:

Let E be the amount of money Ethan starts with, J be the amount Jun Wei starts with, and R be the amount Raj starts with. Let M be the total amount of money to start with.

To start:

[tex]E:J:R = 5:6:9[/tex]

This means Ethan has 5/20 of M, the money to start with. This reduces to 1/4 of M.

Afterwards:

[tex](E-50):J:R = 3:4:6[/tex]

This means Ethan has 3/13 of the remaining money (which is M-50!) after giving up 50. So

E = (M/4), or 4E = M

and

[tex](E - 50) = 3/13 * (M - 50)[/tex]

We know 4E = M, so we can substitute that in:

[tex](E - 50) = 3/13 * (4E - 50)E - 50 = (12/13)E - 150/13E - 650/13 = (12/13)E - 150/13(1/13)E = 500/13E = 500[/tex]

That's how much money Ethan had to start with. But we're asked how much he has AFTER giving $50 away, so that's $450.

In this problem, you need to remember that radius is half the diameter.

STEP 1: Divide the diameter in half.

STEP 2: Multiply your answer by itself. (example: if your answer was 8, you would multiply by 8)
