Step-by-step explanation:
The perimeter of the rectangle is 28 units.
What is the value of w?
O 5 units
0 7 units
w
14 units
2w-1
O
15 units
The value of w according to the given description is; 5units
Perimeter of a rectangleThe perimeter of a rectangle is given as;
P = 2 (l + w)
Hence, In this scenario;
28 = 2 (w + 2w -1)
28/2 = 3w -1
14 + 1 = 3w
3w = 15
w = 5.

In a new scale drawing of the same room, the length of the room measures 4 inches. What is the scale of the new drawing?
Answer:
6 feet = 1 inch
Step-by-step explanation:
The actual length of the room = 24 feets
The new scaled lengtb of the room = 4 inches
The scale of a drawing = actual length / scaled or model length
Hence, scale used = 24 feet / 4 inch = 6 feet / 1 inch
The scale of the new drawing :
6 feet : 1 inch
6 feet length of actual room length is equivalent to 1 inch length on the drawing

lemonade to the school picnic, and
Shelby brought 16 quarts of orangeade.
How many gallons did the two girls
bring to the school picnic?
Answer: 25 Gallons

Answer:
Step-by-step explanation:
Let's baby-step this to make it easy, ok? Begin by getting rid of all the fractions, which means we will eliminate the 3 from the 1/3 by multiplying both sides be 3:
[tex]3V=\pi r^2 h[/tex]
If we want to eventually isolate the r, we need to move the h and the pi. Do this by division, since each of these is multiplied by r-squared. Doing that gives us:
[tex]\frac{3V}{\pi h}=r^2[/tex]
Lastly, to undo a square, we have to take the square root. We will do that for both sides of the equals sign:
[tex]+\sqrt{\frac{3V}{\pi h} }=r[/tex]
The positive is out front there to indicate that we don't want the negative value since distance is a measure that will never be negative.
The half-life of a radioactive kind of radium is 11 days. If you start with 72 grams of it, how
much will be left after 22 days?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Radioactive decay.
N(t) = 72(1/2)^22/11
==> N(t) = 72 (1/2)^2
==> N(t) = 72/4
==> N(t) = 18 grams.
So the remaining would be 18 grams.
Which way is the wind blowing in relation to the land and ocean?
Answer: Hope This Helps!
Step-by-step explanation:
This wind happens to be the sea breeze. The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
Answer:
When the air mass above the land becomes cooler than the air mass over water, the wind direction and convective cell currents reverse and the land breeze blows from land out to sea.

Find the value of x
:]]]]
Answer:
175 degrees
Step-by-step explanation:
So we see that this is a supplementary angle, which means it is equal to 180/ So set the equations up and solve for x:
[tex]180=29+(x-5)\\180=24+x\\156=x\\[/tex]
Then, plug 156 back into the equation:
[tex]180-5\\175[/tex]
Therefore, your answer is 175 degrees
The lifespan of a hamster is 4 years less than that of a rabbit. The lifespan of a raccoon is 2 times that of the hamster. If the total lifespan of the animals is 24 years, calculate the longevity for the rabbit.
Answer:
9 years
Step-by-step explanation:
Let
Lifespan of rabbits = x
Lifespan of hamster = x - 4
Lifespan of raccoon = 2(x - 4)
Total lifespan of animals = 24
Total = rabbits + hamster + raccoon
24 = x + (x - 4) + 2(x - 4)
24 = x + x - 4 + 2x - 8
24 = 4x - 12
24 + 12 = 4x
36 = 4x
x = 36/4
x = 9 years
longevity for the rabbit = 9 years
Lifespan of rabbits = x = 9
Lifespan of hamster = x - 4
= 9 - 4
= 5
Lifespan of raccoon = 2(x - 4)
= 2(9 - 4)
= 2(5)
= 10
Total lifespan of animals = 24
Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the fifth number.
Answer:
17
34
Step-by-step explanation:
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14
let x = missing number
14 = x - 20
x = 20 + 14 = 34
or
14 = 31 - x
x = 31 - 14
x = 17

You have a set of 10 cards numbered 1 to 10. You choose a card at random. Event A is
choosing a number less than 8. Event B is choosing an even number. Calculate the
probability of A NB.
P(A NB) =
Answer:
35% or 35/100
Step-by-step explanation:
Gage Millar, Algebra 2 tutor
Choosing a number LESS than (not equal to 8) is 7/10 (1,2,3,4,5,6,7)
Chosing an even number is 5/10 (2,4,6,8,10)
so just multiply 7/10 x 5/10 to get 35 over 100, or a 35% chance
