Step-by-step explanation:

The set of side lengths which does not form a right triangle is 9m, 11m, 13m

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

AB = 9 m

BC = 11 m

AC = 13 m

Now , for a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

AC² = AB² + BC²

On simplifying , we get

13² = 9² + 11²

169 ≠ 81 + 121

Hence , the sides 9m, 11m, 13m does not form a right triangle

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2/5 x −9< 1/2

Step 2: Add 9 to both sides.

−2/5x −9+9< 1/2+9 −2/5x x< 19/2

Step 3: Multiply both sides by 5/(-2).

Answer:

You could mow 20 yards in 16 hours.

Step-by-step explanation:

You can mow 20 yards in 16 hours because half of 16 is 8 and in the question it says that it took 8 hours to mow 10 yards and 8x2=16 so if you multiply 10 by 2 then you would get your answer, 20 yards.

Answer:

20

Step-by-step explanation:

we can find it by using proportions which is the harder way

16/8=x/10

16(10)=8x

160=8x

/8. /8

20=x

20 lawns

The easiest way is that was know 10 lawns is from 8 hours and if we divide 16 by 8 we get 2 so we just have to multiply the 10 lawns by 2 to get 20

Part a) You could build 5 copies of the flower pattern  

Part b) You would have 40 red trapezoids left over

Step-by-step explanation:

The complete question in the attached figure

Part a)

Let

x -----> the number of yellow hexagons

y ----> the number of red trapezoids

z ----> the number of green triangles

we know that

The flower pattern has the following ratios

Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles

1) For x=30

Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)

Verify the quantity of y needed and the quantity of z needed

Find the value of y

10 < 50 ----> is ok

Find the value of z

45<60 --->is ok

2) For y=50

Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)

Verify the quantity of x needed and the quantity of z needed

Find the value of x

150 > 30 ----> is not ok

3) For z=60

Divide 60 by 9 (remember that in one pattern there are 9 green triangles)

60/9=6.7 copies

Round down

6 copies -----> 6(9)=54 green triangles

Verify the quantity of x needed and the quantity of y needed

Find the value of x

36> 30 --->is not ok

therefore

You could build 5 copies of the flower pattern

Part b)

we know that

x:y:z=6:2:9

If you build 5 copies

1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over

2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over

3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over

therefore

You would have 40 red trapezoids left over

Answer: x=230 and y=75

Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So

Second patio:

(x-10),60+80 = 360

x-10+140 =360-140

x-10=220+10

x=230

First patio:

(x+10)+(y+5)+40 = 360

x+y+55=360

x+y=360-55

x+y=305- x(230) =75

y=75

Answer: x = 50, y = 75

The sum of angles of a triangle is equal to 180°

according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)

(x-10) + 60 + 80 = 180 -- eq(2)

(x - 10) + 140 = 180

x - 10 +140 = 180

x + 130 = 180 , x = 180 - 130

x = 50

put x value in eq(1)

50+10 + (y+5) + 40 = 180

60+(y+5)+40 = 180

y+5 +100 = 180

y + 105 = 180

y = 180 - 105

y = 75

So, x = 50 and y = 75.

756 in scientific notation is 7.56x10^2

Step-by-step explanation:

Answer:

7.56x10^2

Step-by-step explanation:

Answer:

Step-by-step explanation:

You want the digits assigned to A, D, G, I, N to satisfy the multiplication problem DID·I = NAG.

Neither D nor I can be 1, because their product is G (not D or I). There can be no carry from that product. (If there were, the result would have 4 digits, not 3.) This means the least significant digit of I·I must be A, and that product must be more than 10.

  I² > 10   ⇒   I ≥ 4

  I ≥ 4   ⇒   D = 2, G = 8 and I = 4

Then we have ...

  DID × I = NAG   ⇒   242 × 4 = 968

The value of NAG is 968.

Answer:

NAG = 968

242 * 4 = 968

2 = D

4 = I
