Answers
Answer:
3x
Step-by-step explanation:
What you know
This is an equilateral triangle
the x's are all the same
you could write x + x + x = 3x = 16
Multiplying is just adding repeatedly
Answer:16 = 3x
Step-by-step explanation:
Perimeter = Sides surrounding a figure
The triangle has 3 sides, each named "x".
Thus, because the perimeter is equivalent to 16 inches, 3x = 16.

Hi answer: 41What I do for these is do the shapes separately and use the appropriate formulas! Then add them Up! So the easiest is the rectangle that would be 5 × 4 = 20 then the triangles would be 5 x 1 = 5 then ÷ by 2 = 2.5 but since there are two of those triangles we just multiply by 2 again so 2.5 × 2 = 5 for the last two triangles at the top it would be 4 × 4 = 16 then ÷ by 2 = 8 but since theres 2 triangles multiply by 2 so 8 × 2 = 16 now we add all of these numbers up so 20 + 5 + 16 = 41 Hope that helps!
Anishaa has read 125 pages of a 405 page book. She reads 20 pages each day. Write an equation that represents how long it will take her to finish reading this book.
Answers
Answer:
Time it would take her to finish the book = 280 / 20
Step-by-step explanation:
Time it would take her to finish the book = amount of pages left / how many pages she reads in a day
amount of pages left = 405 - 125 = 280
pages she reads in a day = 20
280 / 20
Take the deepest dive of an elephant seal and add it to the deepest seawater scuba dive by diver John Bennet. The result is 6,024 ft. Two times the elephant seal's depth minus Bennet's depth is 9,024 ft.
Answers
Answer:
[tex]x = 5016[/tex]
[tex]y = 1008[/tex]
Step-by-step explanation:
Given
Let:
[tex]x \to Elephant\ seal[/tex]
[tex]y \to Bennet[/tex]
From the first statement, we have:
[tex]x + y = 6024[/tex]
From the second, we have:
[tex]2x - y = 9024[/tex]
Required
Find x and y
Add both equations to eliminate y
[tex]x +2x + y - y = 6024 + 9024[/tex]
[tex]3x = 15048[/tex]
Divide both sides by 3
[tex]x = 15048/3[/tex]
[tex]x = 5016[/tex]
Substitute [tex]x = 5016[/tex] in [tex]x + y = 6024[/tex]
[tex]5016 + y = 6024[/tex]
Solve for y
[tex]y = 6024 - 5016[/tex]
[tex]y = 1008[/tex]

- Solo,
Answers
Answer:
√17 units
Step-by-step explanation:
(6, 8) & (7, 4)
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Plug in the values you know.
[tex]d = \sqrt{(7 -6)^2 + (4 -8)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(1)^2 + (-4)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(1) + (16) }[/tex]
Add.
[tex]d = \sqrt{(17)[/tex]
Evaluate the square root.
[tex]d=\sqrt{17}[/tex]
This square root is already fully simplified.
Your answer is √17 units.

In a cave, a stalactite gets 4 millimeters longer each year. This year it is
72 centimeters
How many years until it is 1 meter long *25 points*
Answers
The number of years it will take until the stalactite is 1 meter long is; 70 years
How to convert units of measurements?
From conversion units, we know that;
1 m = 100 cm
1 cm = 100 m
Current length is given as 72 cm
Thus;
Length after x years = 1 m = 100 cm
Length increase in x years = 100 -72 = 28 cm
Since 1 cm = 10 mm
Then;
Length increase in x years in mm = 28 * 10 = 280 mm
Thus;
Length increase in 1 year = 4 mm
Length increase in x years = 4x mm
Then; 4x = 280
x = 70
Thus, it will take 70 years until it is 1 meter long.

(I’ll give brainliset) Your friend makes a two dimensional model of a dividing cell as shown. The total area of the dividing cell is 350 square inches. What is the area of the shaded region to the nearest whole inch?
nearest whole inch?
Answers
Answer:
149.04 in^2
Step-by-step explanation:
The image of the question can be seen below.
In the image, we can see two circles that intersect at a given point.
We know that the total area of the image is 350 in^2
We want to find the area of the shaded part.
Ok, this seems to be hard, so instead, let's find the area of the two non-shaded parts (two semicircles) and just subtract that area from the total area of 350in^2
The two non-shaded parts are half a circle of diameter 16 inches.
We know that for a circle of diameter D, the area is:
A = pi*(D/2)^2
Where pi = 3.14
And because we want to find the area of two semicircles of diameter 16 inches, is exactly the same as finding the area for a single circle of diameter 16 inches.
This is:
A = 3.14*(16in/2)^2 = 3.14*(8in)^2 = 200.96 in^2
Now we can just subtract this from the total area:
shaded area = total area - A
shaded area = 350 in^2 - 200.96 in^2
shaded area = 149.04 in^2

A competitive diver dives from a 33-foot high diving board. The height of the diver in feet after 't' seconds is given by u(t) = −16t^2 + 4t + 33. At the moment the diver begins her dive, another diver begins climbing the diving board ladder at a rate of 2 feet per second. At what height above the pool deck do the two divers pass each other? Please answer it quickly, it's for my homework.
Answers
Answer:
[tex]t = 0.375s[/tex]
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 4t + 33[/tex] --- driver 1
[tex]Rate = 2ft/s[/tex] -- driver 2
[tex]height = 33ft[/tex]
Required
The time they passed each other
First, we determine the function of driver 2.
We have that:
[tex]Rate = 2ft/s[/tex] and [tex]height = 33ft[/tex]
So, the function is:
[tex]h_2(t) = Height - Rate * t[/tex]
[tex]h_2(t) = 33 - 2t[/tex]
The time they drive pass each other is calculated as:
[tex]h(t) = h_2(t)[/tex]
[tex]-16t^2 + 4t + 33= 33 - 2t[/tex]
Collect like terms
[tex]-16t^2 + 4t + 2t= 33 - 33[/tex]
[tex]-16t^2 + 6t= 0[/tex]
Divide through by 2t
[tex]-8t + 3= 0[/tex]
Solve for -8t
[tex]-8t = -3[/tex]
Solve for t
[tex]t = \frac{-3}{-8}[/tex]
[tex]t = 0.375s[/tex]

A dime is dropped from a building at a
height of 1,024 ft. If the equation for
height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the dime to
hit the ground?
[?] seconds
Answers
Answer:
8 seconds
Step-by-step explanation:
Given :
h(t) = -16t2 + initial height
Initial height = 1024 feets
By the time it hits the ground, h(t) = 0
Equation becomes :
0 = - 16t² + 1024
Solve for t
-16t² = 1024
t² = 1024 / -16
t² = 64
t = √64
t = 8
Hence, it will take 8 seconds
