A number b minus 4.2 is less than −7.5

Answers

Answer 1

Answer:

Answer:

Given: A number b minus 4.2 is less than -7.5.

Here, b is the number.

"less than" symbol is represented by '<'

"minus" means subtract.

"b minus 4.2" translated to b - 4.2

Then, our inequality becomes;

$b - 4.2 < -7.5$

To solve for b;

Add 4.2 both sides we get;

$b -4.2 + 4.2 < -7.5 + 4.2$

Simplify:

$b < -3.3$

Therefore, an inequality for the given word sentence is, $b - 4.2 < -7.5$

Answer 2

Answer: b - 4.2 < -7.5
subtract b and 4.2
less then sign is <
then <-7.5

On a scale drawing , a rectangular room has width = 14 cm & length = 22 cm. The scale is 1 cm = 0.5 m .
Work out the real area of the room in square meters .
area =

Answers

SO Area formula is
AREA = length × width
A = L× W
For length:
1cm\0.5m = 22cm/?m We don`t know about the meter.
if we cross multiply the answer will be 11m.
For width:
1cm\0.5m = 14cm\?m We don`t know about the meter.
if we cross multiply the answer will be 7m.
The square meter should be 77
Because 11 × 7 = 77

14 x 0.5 = 7

22 x 0.5 = 11

7 x 11 = 77 square meters

Find the distance between the pair of points . (-3,-6) and (-3, 1)

Answers

Answer:

Step-by-step explanation:

add 6 to -6 to get 0

than add 1 to 0 to get 1

6+1=7

Final answer:

The distance between the points (-3,-6) and (-3, 1), both lying on the same vertical line, is found by subtracting their y-coordinates. The distance is 7 units.

Explanation:

The subject of this question is in the field of Math, specifically focusing on the concept of distance between two points in a plane. In this case, you are asked to find the distance between the points (-3,-6) and (-3, 1). The calculation is very straightforward as both points lie on the same vertical line where the x-coordinate of both points is -3. To find the distance between two points which lie on the same line , we can simply subtract the two y-coordinates.

So, the distance is given by the absolute value of the difference between the y-coordinates: |1 - (-6)| = |1 + 6| = |7| = 7.

So, the distance between (-3,-6) and (-3,1) is 7 units.

The circumference of a circle is C = 7.64(pi) inches. what is the length of the radius and diameter.

Answers

The exact circumference is shown there. The exact circumference has the length of the diameter and pi. Like, say a diameter was 8 inches. It would be 8(pi).

The diameter here is 7.64 inches. A radius is half as big as a diameter, so divide the diameter by 2. The radius is 3.82 inches.

Hope this helps!
