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.

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 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.

Answer:
146
Step-by-step explanation:
angle AB is an inscribed angle and arc AB is it's intercepted arc
An inscribed angle is equal to half the measure of its intercepted arc
Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle
Thus, arc ab = 2(73)
2 * 73 = 146
hence, arc AB = 146
Answer:
mAB = 146°
Step-by-step explanation:
We can notice that the angle given is an inscribed angle and an inscribed angle is 1/2 the arc it intercepts. We can set up an equation to model the situation:
73° = 1/2(mAB)
mAB = 146°

Write an expression for the sequence of operations described below add 3 to b, then triple the result
Answer:
9 + 3b
Step-by-step explanation:
This is a rather very simple question to solve. And the first step is to look at the variables given.
From the question, we're told to add 3 to b
This means that
3 + b
Then, we are told to triple the result. This means that we multiply it by 3.
3 (3 + b)
And when we open the brackets, we have something like this
9 + 3b

The sum of two numbers is 65. The larger number is five more than three times the smaller number. What are the numbers? (Systems of Equations)
Answer:
x=44 and y=21
Step-by-step explanation:
The large one is x
The small one is y
According to given conditions,
x+y=65[Sum of two number is 65]—Equation(1)
x-23=y [Smaller number is less than 23 than larger]——Equation (2)
From equation (2) we can write,
x-y=23——-Equation(3)
Now adding equation (1) and (3) we get,
x+y+x-y=65+23
=>2x=88
=>2x/2=88/2 [Both sides are divided by 2]
=>x=44
Now putting the values in equation (2) we get,
44–23=y
=>y=21
Large, x=44 and Small, y=21

Aquarium has a height of 25 inches and a radius of 21 inches what is the volume of the aquarium in cubic inches
Answer:[tex]34,650\ in^3[/tex]
Step-by-step explanation:
Given
The height of the aquarium is [tex]h=25\ inches[/tex]
The radius of the aquarium is [tex]r=21\ inches[/tex]
Assuming aquarium to be in the shape of a cylinder
So, its volume is [tex]V=\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 21^2\times 25\\\Rightarrow V=34,650\ in^3[/tex]
Thus the volume of the aquarium is [tex]34,650\ in^3[/tex].

Four streets feed into a roundabout circle as shown below. If the diameter of the
roundabout is 130 feet, find the approximate distance a car will travel between Cole Street
and Maple Street along the roundabout.
Answer:
The answer is C. 119.1
Step-by-step explanation:
The arch measure between Cole St. and Maple St. is 105 degrees which is equal to 7/24 of the circumference. since the diameter is given simply multiply the circumference by 7/24 which equals 285,887/2400. Divide these and you get your answer.
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
