PLEASE PUT STEPS BY STEPS TY :,)

Answer:

-4

Step-by-step explanation:

if you multiply 38 x 640 it will be 24320, and if you multiply 18 x 38 it will be 684. add 24320 and 684 it will be 25004 which means she has -4 dollars i believe

Answer:$14

Step-by-step explanation:

640x38 = 24,320

25,000-24,320 = 680

680/18 = 37.7777 and on

so you would make that 37 chargers she can buy with the remaining money.

37x18 = 666 and 680-666=14

Answer:

70 minutes OR 1 hour and 10 minutes (it's the same thing)

Step-by-step explanation:

So this can be modeled by the equation 20/150=x/525

so solving for x, you have to say whats the most times that 150 will go into 525 without going over

the answer is 3

so 150x3=450 and 525-450=75

75 is one half of 150 so it would be 3.5

multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes

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.

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

Step-by-step explanation:

The product of 5 and 11 is 55.

When a question says "product" it means you have to multiply both numbers, so 5 x 11 is 55.

Get it in your head

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

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
