Answer:

Because the side of the triangle forms pythagoras tripple

Line AB = √10

Line BC = 10

Line AC = √90

Step-by-step explanation:

From the question,

In the triangle,

Line AB = √[(8-5)²+(5-6)²]

Line AB = √(3²+-1²)

Line AB = √(9+1)

Line AB = √10

Also,

Line BC = √[(2-8)²+(-3-5)²]

Line BC = √(-6²+(-8)²)

Line BC = √(36+64)

Line BC = √100

Line BC = 10 unit.

Finally,

Line AC = √[(5-2)²+(6+3)²]

Line AC = √(3²+9²)

Line AC = √(9+81)

Line AC = √90.

From the above length of the line in the triangle,

Line AC, Line BC and Line AC are pythagoras triple.

I.e

10² = (√10)²+(√90)²

100 = 10+90

100 = 100.

Note only a a right angle triangle obeys pythagoras theorem.

Answer: Willie runs 11 miles in 77 minutes.

Step-by-step explanation:

To know how many miles he will run in 77 minutes we first need to know how much minutes it takes for Willie to run 1 mile.

28/4 = 7 minutes per mile.

We now want to know how much miles Willie will run if he runs for 77 minutes.

77/7 = 11 miles.

Willie runs 11 miles in 77 minutes.

Answer:

Willie can run 11 miles in 77 minutes

Step-by-step explanation:

I did 28/77 and got 2.75. I then multiplied 2.75 and 4 to get 11.

Therefore, Willie can run 11 miles in 77 minutes.

Answer:

Step-by-step explanation:

First add all of the numbers together

25+22+13+14+21=82

Now add a variable like X since we don't know the age of the sixth, and divide it by 6 since there are 6 people in the class.

82+X/6=22

(22 is the mean age)

Now solve for the equation

82+X=132

so X =50

Answer:

First angle would be 31°, second angle would be 59°

Step-by-step explanation:

You can use the equation 90° = a + (2a - 3°), where a is the measure of your smaller angle.

simplify:

90° = 3a - 3°

93° = 3a

31° = a

let your second angle equal (2a - 3°)

(2(31°) - 3°) = 59°

Hello There!

This is an example of a 30 - 60 - 90 triangle

We are given the long leg and we need to find the hypotenuse

First we want to find the shorter leg

To do so we just take away the [tex]\sqrt{3}[/tex] from the 4[tex]\sqrt{3}[/tex]

so the shorter leg is equal to 4

Now to find the hypotenuse

Well according to the 30-60-90 triangle rule

the hypotenuse is equal to twice the size of the short leg

4*2=8

hence, the answer is option 2

Answer:

D. 30 cm

Step-by-step explanation:

A rectangle has two of the same sides and two of another length so it would be 9+9+6+6, which is 30

Answer:

d) 30 cm

Step-by-step explanation:

P = 2 (l + w)

P = 2 (9 + 6)

P = 2 (15)

P = 30

30 sq. cm woul'd be wrong because that's indicating the area (you don't use sq. when finding perimeter)

3:D

Step-by-step explanation:

To solve these questions you need to know the exterior angle theorem.

1: 8x+2+9x+6=110

17x+8=110

17x=102

x=6

2: 30+98=?

so 128

3: 9x+11+9x+5=124

18x+16=124

18x=108

x=6

Answer:

Step-by-step explanation:

If [tex]f(x) = x[/tex]. then you would use the x in that equation to plug in for the x in the equation [tex]g(x)=[/tex] [tex]-x^{2} - 2[/tex]

Answer:

Chloe will refill the bird feeder every 11 weeks.

Step-by-step explanation:

Since Chloe has a bird feeder in her yard, which when it is full of bird seed, it weighs 1234 pounds, and the birds eat 112 pounds of bird seed each week, since she refills the bird feeder when it weighs less than 3 pounds, to determine which equation represents how many weeks, W, it will take until Chloe refills the bird feeder, the following calculation must be performed:

(1234 - 3) / 112 = W

1231/112 = W

10.99 = W

So, Chloe will refill the bird feeder every 11 weeks.

Desmos is a tool to finding your answer to this equation. Its a graphing calculator

Answer:

x=2

Step-by-step explanation:

y=3x+2

y=x+6

Since you're stating that, they both equal because equation is equated to equation 2 because of the Y.

Therefore, substitute into both equations as shown:

3x+2=x+6

3x-x=6-2  (bring 2 to the other side by subtracting 2 as well as x)

2x=4

2x/2=4/2  (dividing 2 on both sides to get rid off 2 in 2x)

x=2.

The solution of the given system of equations y=3x+2 and y=x+6 using the substitution method will be x = 2 and y = 8.

More than one variable may be present inside a linear equation.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

As per the given system of equations,

y=3x+2 and y=x+6

Compare both values,

3x + 2 = x + 6

3x - x = 6 - 2

x = 4/2 = 2

And, y = 2 + 6 = 8

Hence "The solution of the given system of equations y=3x+2 and y=x+6 using the substitution method will be x = 2 and y = 8".
