Answer:
31.4
Step-by-step explanation:
To find circumference, the formula is A=pi*r^2. The radius is 1/2 the diameter. The radius of the donut is 3.5. 3.5^2 is 12.25. Pi is approximately 3.14, so 12.25*3.14 is 38.465. The donut hole takes away from the circumference, so we have to subtract the circumference of the donut hole from the donut. 1.5^2 is 2.25, and 2.25*3.14 is 7.065. 38.465-7.065 is 31.4. The circumference of the circle is 31.4.

the area of the triangle below is 29.25 square centimeters the height is 6.5. what is the length of the base?
Answer: 9
Step-by-step explanation:
½bh = 29.25
½ × 6.5 × b = 29.25
B= 29.25/ 3.25
The length of the base of the triangle is 9 centimeters.
What is the base length of the triangle?The area of a triangle is simply expressed as half base multiplied by height.
Area A = 1/2 × base length × height
Given the dimensions of the triangle:
Area A = 29.25 square centimeters
Height = 6.5 centimeters
Base length =?
To find the height of the triangle, plug the given values into the above formula and solve for h:
Area A = 1/2 × base length × height
29.25 = 1/2 × base length × 6.5
29.25 = base length × 3.25
Base length = 29.25 / 3.25
Base length = 9 cm.
Therefore, the base length measures 9 centimeters.

4n^2-15n-25 factor trinomials pls help me on this i would love if you would put the steps too thank you
---Multiply a x c
Quadratic Form: ax^2 + bx + c
4 x -25 = -100
---Find a factor pair of -100 that adds up to -15
-20 x 5 = - 100
-20 + 5 = -15
---Separate the b term into your two factors
4n^2 + 5n - 20n - 25
This can take some trial and error (though there are only two options) because when you factor, you want the inside of the parentheses to be the same. If you look at the next step, (4n + 5) appears twice.
---Factor each binomial
n(4n + 5) - 5 (4n + 5)
---Rewrite
(n - 5)(4n + 5)
What you're really doing here is factoring out the (4n + 5), which leaves you with the terms that you factored out in the previous step. You then combine these terms into one set of parenthesis.
Answer: (n - 5)(4n + 5)

How to find the density and volume?She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.
The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.
Then the volume of the coffee in each tank will be
We know that the dimension of both tanks is equal. Then the volume will remains equal.
Volume = L × B × H
Volume = 8.75 × 8.75 × 23
Volume = 1760.9375 ≅ 1760.94 in³
Then the mass of the coffee in each the tank will be
The mass of hot coffee will be
Mass = Density × Volume
Mass = 5.8 × 1760.94
Mass = 10213.45 oz
The mass of cold coffee will be
Mass = Density × Volume
Mass = 3.5 × 1760.94

the perimeter of an equilateral triangle is 6cm find its area
Answer:
√3 cm
or
1.73 cm to the nearest hundredth.
Step-by-step explanation:
Each side must be 2 cm long
Using Heron's formula
Area = √(s(s-a)(s-b)(s-c) where s = semi-perimeter, a , b and c are the 3 side lengths.
So here s = 6/2 = 3 and all the sides = 2 so
Area = √(3(3-2)^3
= √3 cm.
Solve this system of linear equations. Separate
the x- and y-values with a comma.
15x = -42 - 19y
3x = -54 - 19y
15x=-42-19y
15x+19y+42=0-(1)3x=-54-19y
3x+19y+54=0--(2)Subtract both
12x-12=012x=12x=1Put in second
3(1)+19y+54=019y+57=0y=-3So
(x,y)=(1,-3)Answer:
1, -3
Step-by-step explanation:
QuestionSolve the system of linear equations:
15x = -42 - 19y3x = -54 - 19y-------------------------------------------------------------------------------------
SolutionSubtract the equations to eliminate y:
15x = -42 - 19y
- 3x = -54 - 19y
----------------------
12x = 12
⇒ x = 12 ÷ 12
⇒ x = 1
Now substitute the found value of x into one of the equations and solve for y:
⇒ 15x = -42 - 19y
⇒ 15(1) = -42 - 19y
⇒ 15 = -42 - 19y
⇒ 19y = -42 - 15
⇒ 19y = -57
⇒ y = -57 ÷ 19
⇒ y = -3
Therefore, x = 1 and y = -3
