Answer:

10 days

Step-by-step explanation:

It will take 10 men 5 days to dig a hole half as big.

It will take 5 men 10 days to dig a hole half as big.

( Remember, the less people, the more time it will take. )

Answer:

10 men can dig 1 hole in 10 days

How long for 5 men to dig ½ hole?

The ratio to be concerned with is

(number of people / number of holes) =  10 days

5 people digging  ½ hole will take 10 days.

Yes they are. Explanation provided below.

Step-by-step explanation:

Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

Answer:

The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical

Step-by-step explanation:

The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

Answer:

4

Step-by-step explanation:

4 times 4 is 16. 7 less than 16 is 9.

Answer:

4

Step-by-step explanation:

You can use a simple formula for finding the answer to problems like these. You read it out and put your information in order and use a variable (such as x) in place of the number.

4 * x - 7 = 9

Then solve by getting your variable alone on one side.

Add 7 to both sides: 4 * x = 16

Divide both sides by 4: x = 4

Answer:

Brainliest plz

Step-by-step explanation:

Area = width × length

16= 8 × (X –5 )

16 = 8X – 40

8X = 16 + 40

8X = 56

X= 56 / 8

X= 7 in

I hope I helped you^_^

Answer: x =

Step-by-step explanation:

Area = width times length

8*(x-5)=16

8x - 40 = 16

8x = 16 + 40

x = 56/8

x = 7

Brainliest, please!

Step-by-step explanation:

r = kp/(st)

p = 12, t = 2, s = 5, r = 18

18 = k(12)/(2)(5)

18 = 12k/10

12k = 180

k = 15

Answer:

Yes.

Step-by-step explanation:

Most people are going to say 4x2=8 so 20x2=40, then do a huge math mess up and think they discounting $1.33 after the first 4. this is incorrect.

Seeing as $20 is 4 tickets we can safely say, each ticket is $5 each.

Basic mathematics, 5x7=35. Paying for 7 tickets at $5 each, that is the correct constant price.

Step-by-step explanation:

I only see one phrase (correcting a typo) : "five more than a number".

that is expressed in math by using "n" for the variable "number " :

n + 5

or

5 + n

as additions and multiplications are commutative, they can be written and executed in any sequence. it is always the same result.

[tex]\\ \sf\longmapsto f(x+4)=3x+4[/tex]

[tex]\\ \sf\longmapsto f(x)=3x+4-4[/tex]

Answer:

Length=13.07 and Breadth=1.07

Step-by-step explanation:

Area=l*b

14=(2x+5)(2x-7)

14=4x^2-4x-35

4x^2-4x-49=0

Using quadratic formula, we have x=(1±5sqrt(2))/2 but as length can't be negative, so x=(1+5*sqrt(2))/2

Length=13.07 and Breadth=1.07
