Answer:

Width <= 5 and length <= 9

Step-by-step explanation:

Width: x

Length: x+4

2x + 2(x+4) <= 28 (less or equal)

2x + 2x + 8 <= 28

4x <= 28-8

x <= 20/4

x <= 5

Answer the picture below.

pav-90 [236]

Answer:

The distance between point M and point L is 8

Step-by-step explanation:

The given points on the coordinate are M = (- 2, 4) and L = (4, - 1)

The formula for determining the distance between two points is expressed as

d = √(x2 - x1)^2 + (y2 - y1)^2

Where

y2 = final value of y = - 1

y1 = initial value of y = 4

x2 = final value of x = 4

x1 = initial value of x = - 2

Therefore,

d = √(4 - - 2)^2 + (- 1 - 4)^2

d = √6^2 + (-5)^2

d = √36 + 25

d = √61 = 8

150 parents were surveyed. 26% said that the kids were noddy and 70% said their kids were nice. How many parents didn't answer w

alexandr1967 [171]

Answer:

The parents who didn't answer with either naughty and nice are <u>6</u>.

Step-by-step explanation:

Given:

150 parents were surveyed. 26% said that the kids were naughty and 70% said their kids were nice.

Now, to find parents who didn't answer with either naughty and nice.

<em>So, as given in question:</em>

<em>70% said that their kids are naughty.</em>

<em>26% said that their kids are nice.</em>

So, to get the percentage of parents who didn't answer we subtract.

<em>Thus, the percentage of parents who didn't answer with either naughty and nice:</em>

100% - (70% + 26%)

100% - 96% = 4%.

Hence, 4% of parents didn't answer.

Now, to get how many parents didn't answer we calculate the percentage of the total who didn't answer:

<em>Total parents surveyed = 150.</em>

<em>Parents who didn't answer = 4% of the total parents surveyed.</em>

$Parents\ who\ didn't\ answer = 4\% of 150.$

$Parents\ who\ didn't\ answer = \frac{4}{100}\times 150.$

$Parents\ who\ didn't\ answer = \frac{600}{100}.$

$Parents\ who\ didn't\ answer = 6.$

Therefore, the parents who didn't answer with either naughty and nice are 6.

From points A and B, the distance between which is 1020 mi, two trains left simultaneously towards each other. The speed of one

telo118 [61]

From points A and B, the distance between which is 1020 mi

The speed of one train was 10 mph greater than the speed of the other one

Let the Speed of first train is x

Speed of second train is x+ 10

Time = 5 hours

Distance = speed * time

Distance traveled by first train = x * 5= 5x

Distance traveled by second train = (x+10) * 5= 5x + 50

the trains had not met yet and were 170 mi apart.

the distance between A and B is 1020 mi, Distance traveled by two trains = 1020 - 170 = 850 miles

Distance traveled by first train + second train = 850

5x + 5x + 50 = 850

10x + 50 = 850

Subtract both sides by 50

10x = 800

x= 80

Speed of first train is 80 miles per hour

Speed of second train is 90 miles per hour
