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.

The area of the parallelogram below is___square meters
Answer:
48 m^2
Step-by-step explanation:
Since this is a parallelogram, you can think of it as taking the triangle off of the left side and reattaching it on the right side to make a rectangle. After you visualize it as a rectangle, you just have to multiply 8 by 6 to get 48 meters squared.

Find the possible value of "a" using the distance formula.
(4,-1) and (a,5) with d = 10
Answer:
[tex]a=12\text{ or } -4[/tex]
Step-by-step explanation:
The distance formula is given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We are given the two points (4, -1) and (a, 5). The distance between them is 10.
Let (4, -1) be (x₁, y₁) and let (a, 5) be (x₂, y₂). Substitute:
[tex]10=\sqrt{(a-4)^2+(5-(-1))^2}[/tex]
Solve for a. Square both sides and simplify:
[tex]100=(a-4)^2+(6)^2[/tex]
Simplify:
[tex]64=(a-4)^2[/tex]
Take the square root of both sides. Since we are taking an even root, we will need plus/minus. Hence:
[tex]\pm\sqrt{64}=\pm8=a-4[/tex]
Solve for a:
[tex]a-4=8\Rightarrow a=12\text{ or } a-4=-8\Rightarrow a=-4[/tex]
So, our two possible points are (12, 5) or (-4, 5).
I need help with geometry
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°

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
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.

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

A box in the shape of a rectangular prism has a length of 3 5/8 inches, a width of 2 1/2 inches, and a height of 4 inches. What is the volume of the box?
Answer:
36 1/4 in³
Step-by-step explanation:
v = 3 5/8 * 2 1/2 * 4
Convert to improper fractions
v = 29/8 * 5/2 * 4/1
Cancel
v = 29/2 * 5/2 * 1/1
Multiply
v = 145/4
Reduce
v = 36 1/4 in³

A train is moving at an average speed of 180 m/s. how long will it take to reach the station. Both stations are 80 km apart?
1 km = 1000 meters.
Find total meters: 80 km x 1000 meters per km = 80,000 meters.
Divide total meters by the given speed:
80,000 meters / 180 m/s = 444.44 seconds.
1 minute = 60 seconds
444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds
Total time = 7 minutes 24.42 seconds
Round as needed.
