In a neighborhood of 72 families. 18 families on one or more cats. Write the number of families who own one or more cat as a fraction. Then write the fraction as a decimal.

Answers

Answer:

0.25

Step-by-step explanation:

The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the  answer is 0.25

Step-by-step explanation:

Significant Figures Rules:

Any non-zero digit is significant.Any trailing zeros after the decimal is significant.Any zeros between 2 significant digits are significant.Zeroes before significant numbers in the decimal place are NOT significant; they are placeholders.

(a)

0.004816 - the zeros are placeholders, so they do not count as sig figs.

(b)

50.00168 - the zeros are between 2 significant figures, so they do count as sig figs.

(c)

0.0009812 - the zeros are placeholders, so they do not count as sig figs

⭐️ I NEED HELP ASAP: Sam and Joe are brothers. Joe is five less than three times the age of Sam. If the product of their ages is 28, how old are Joe and Sam?

Please explain how you solved it too! Thank you!

Answers

Answer:

joe=6

Sam=11

Step-by-step explanation:

lets see...

i explain 1by1

firstly we know that joe is 5 - 3 x Sam

(read the sentences VERY CAREFULLY)

then, we put Sam as math variable "s"

it will be; 5-3 x S

[tex]5 - 3 \times s[/tex]

the total of their age is 28

[tex]5 - 3 \times s = 28[/tex]

simplify it

it will be 5-S3=28

then you will get 11 right

that will be sam's age

-5 and it will be Joe's age

A figure with 4 sets of parallel sides is graphed on a grid. The figure is then rotated 90 degrees clockwise. How many pairs of parallel sides does the figure have after the rotation?

Answers

Answer:

Step-by-step explanation:

After being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

What is 90° rotation of an object?

The transformation P(x, y) P' can be used to represent a 90° rotation for any point in the plane (x, y) (-y, x). This transition can be produced by applying two reflections.Transformation involves moving a shape from one position to another  

Given data ,

A figure with 4 sets of parallel sides is graphed on a grid

The figures with 4 sets parallel sides are : Rhombus, Square , Rectangle

The figure is then rotated 90° clockwise

Now ,

90 degrees clockwise transformation carries the square , rhombus as well as the rectangle onto itself that is after rotation there will be 4 pairs of parallel sides

Hence , after being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation

Answers

Answer:

5 - (1 + 20) = yx

Step-by-step explanation:

So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30.75 altogether. How much money did each boy receive?

Answers

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.

did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.

Answers

(B) 4 hr is the correct answer.

Explanation :

★ Speed of body is defined as the ratio of distance travelled to the time taken[tex].[/tex]

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

⭆ time = 4 hr

Having completed my studies there, I was duly attached to the Fifth Northumberland Fusiliers as Assistant Surgeon. The regiment was stationed in India at the time, and before I could join it, the second Afghan war had broken out. On landing at Bombay, I learned that my corps had advanced through the passes and was already deep in the enemys country. I followed, however, with many other officers who were in the same situation as myself, and succeeded in reaching Candahar in safety, where I found my regiment, and at once entered upon my new duties. The campaign brought honors and promotion to many, but for me it had nothing but misfortune and disaster. I was removed from my brigade and attached to the Berkshires, with whom I served at the fatal battle of Maiwand. There I was struck on the shoulder by a Jezail bullet, which shattered the bone and grazed the subclavian artery. I should have fallen into the hands of the murderous Ghazis had it not been for the devotion and courage shown by Murray, my orderly, who threw me across a pack-horse, and succeeded in bringing me safely to the British lines. Worn with pain, and weak from the prolonged hardships which I had undergone, I was removed, with a great train of wounded sufferers, to the base hospital at Peshawar. Here I rallied, and had already improved so far as to be able to walk about the wards, and even to bask a little upon the verandah, when I was struck down by enteric fever. For months my life was despaired of, and when at last I came to myself and became convalescent, I was so weak and emaciated that a medical board determined that not a day should be lost in sending me back to England. I was dispatched, accordingly, in the troopship Orontes, and landed a month later on Portsmouth jetty, with my health irretrievably ruined.What do the narrators actions reveal about his character?A) He is heroic.
