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
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.

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.
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

⭐️ 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!
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
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?
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.

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

A pair of parallel lines is cut by a transversal:
A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees.
What is the measure of angle x?
10 degrees
15 degrees
45 degrees
60 degrees
15 degree or watt quite not sure

Answer:
45 degrees
Step-by-step explanation:
Alternate interior angles where a transversal crosses parallel lines are congruent:

Andrew participated in a bicycle race. The total distance covered was 56
miles. If he cycled at a constant rate of 14 miles per hour, how much time
did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.
(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/timeGiven that,
distance = 56 miles
speed = 14 miles per hour
By substituting the values, we get
⭆ time = distance/speed
⭆ time = 56/14
⭆ time = 4 hr

6x = x^2+ 19
Answer:
as below
Step-by-step explanation:
6= x^2 + 19
x^2=6-19
x^2 = - 9
sqrt ( x^2) = sqrt (-9) :o sqrt of a negative? yes.. use i for the negative.. this is a complex number .. hope you've been studying those
x = i* sqrt (9)
+- x = i3 so there are technically two answers
x=i3
and -x=i3 often times the negative answer makes no sense.. so you discard it

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?
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.
