Multiply the decimal numbers 37.4 x 2.2 =

Advocard [28]

Basically you multiply like normal and then add in the decimal point (to figure out where it goes count how many numbers are behind the decimal (in this case 2) and then count that many places from the right into your answer and that's where it goes). So here 374 x22 =8228 but when you add in the decimal you get 82.28 :)

The set of natural numbers x that satisfy x + 8 = 5

Maksim231197 [3]

Answer:

The set of natural numbers can be denoted as: {} (null set) because no natural number will satisfy the given equation.

Step-by-step explanation:

Given equation:

$x+8=5$

To find the set of natural numbers that satisfies the above equation.

Solution:

In order to find the set of solutions for the equation, we will solve it for $x$

We have:

$x+8=5$

Subtracting both sides by 8.

$x+8-8=5-8$

∴ $x=-3$

Thus, we get only one solution for $x$ that satisfies the given equation but it is not a natural number. -3 is an integer.

Set of natural numbers {1,2,3,4,5,6........}

Thus, we can say the set of natural numbers that satisfies the equation is a null set {}.

Lisa ran around a rectangular field 150 m long and 50 m wide at an average speed of 100 m/min. How long did she take to complete

Anarel [89]

Answer:

20 minutes

Step-by-step explanation:

To make one round of the field, Lisa will have to cover the entire perimeter of the field.

The perimeter of a rectangle = 2(l+w) Where L = length and W = width.

The multiplication of 2 means two lengths and widths that each rectangle has. The perimeter of the field = 2(150 +50) = 400m

Lisa's average running speed = 100m/min

The time taken to cover one round of the field or one perimeter of the field = 400/100 = 4 minutes.

To cover 5 rounds or 5 perimeters Lisa will take 5x4 minutes = 20 minutes.

Nonamiya [84]

He starts with 10, +5 after every week
week 2=10+5
week 3=10+5*2
...
week 25 =10+5*24
f(x)=10+5(x-1)
so during the 25th week=10+5*24=10+120=130

The two numbers in between which the lower quartile value given by the attached boxplot falls are 1.5 and 2.5 respectively.

The lower quartile means the 25th percentile or lower $\frac{1}{4}th$ of the distribution

From a boxplot, the lower quartile is the point marked by the starting point of the box.

The Lower quartile of the distribution represented by the boxplot is 2

The values which bounds the lower quartile value to the left and right are 1.5 and 2.5 respectively.

Therefore, two numbers in between which the lower quartile value falls are 1.5 and 2.5
