1. What is the area of the triangle below?
10 in.
7 in.
Hi!
Triangle Area Formula:[tex]\cfrac{bh}{2}[/tex]
Where b = base and h = height.
In the given problem, the base and height of the triangle are 10 inches and 7 inches.
Now, we can use the formula above.
If we plug in the given values, we have:
[tex]\dfrac{10*7}{2}[/tex]
Multiply 10 and 7:
[tex]\dfrac{70}{2}[/tex]
Divide:
[tex]35[/tex]
Using the triangle area formula, we have gotten a value of 35.
Therefore, the area of the triangle is 35 inches squared.

Answer:
35 inches²
Step-by-step explanation:
Given Base and Height of triangle: 10 inches and 7 inches
To determine the area of a triangle, multiply the base and the height. Then divide the product of the base and the height by 2.
Therefore, the "area of triangle" formula is:
[tex]\boxed{\text{Area of a triangle} = \frac{\text{Base} \times \text{Height}}2}[/tex]
Now, substitute the base and the height in the formula. Then, simplify the expression to determine the area of the triangle provided.
[tex]\implies \text{Area of the triangle} = \dfrac{\text{10} \times \text{7}}2}[/tex]
[tex]\implies \text{Area of the triangle} = \dfrac{70}2} = \boxed{35 \ \text{in}^{2}}[/tex]
Therefore, the area of the triangle is 35 inches².

Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
The volume and the radius are given. (V=45π, r=3)
1. Solve for height
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
2. Plug the new radius (3*3=9) into this formula and solve for "V"
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π

What is the volume of the right rectangular prism? Enter your answer in the box.
Answer:
1000 cm²
Step-by-step explanation:
Given:
Length = 10 cmWidth = 12.5 cmHeight = 8 cmFormula:
[tex]\text{Volume = Length} \times \text{Width} \times \text{Height}[/tex]
Substitute the length, width, and the height of the prism to determine the volume of the prism.
[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]
Simplify the right hand side of the equation, as needed;
[tex]\implies \text{Volume = 10} \times 12.5 \times 8[/tex]
[tex]\implies \text{Volume =}\ 125 \times 8[/tex]
[tex]\implies \boxed{\text{Volume =}\ 1000 \ \text{cm}^{2} }[/tex]
Therefore, the volume of the prism is 1000 cm².

Urgent! Find the length of the tangent segment AC given circle B below
Answer:
AC ≈ 12
Step-by-step explanation:
the angle between the tangent AC and the radius BC is 90°
then Δ ABC is right
note that BC = 9 ( radius of circle )
using Pythagoras' identity in the right triangle
AC² + BC² = AB²
AC² + 9² = (9 + 6)² = 15²
AC² + 81 = 225 ( subtract 81 from both sides )
AC² = 144 ( take square root of both sides )
AC = [tex]\sqrt{144}[/tex] = 12
give two coterminal angles (one positive and one negative) and the reference angle -4 pi/5
The coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.
What is coterminal angles?Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
-4π/5
To find the coterminal angle, add and subtract by 2π in the angle -4π/5
Coterminal angle:
= -4π/5 - 2π
= -14π/5
= -4π/5 + 2π
= 6π/5
Reference angle:
= π - 4π/5 (as the angle lies in the second quadrant)
= π/5
Thus, the coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Answer:
30/45 or 2/3
Step-by-step explanation:
If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:
Numerator = 10 (a + b)
Denominator = 9 (x - y)
Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:
Numerator = 10(3)
Denominator = 9(5)
Therefore, the answer is 30/45, or 2/3.

Step-by-step explanation:
the volume of a cylinder is
base area × height.
and the base is a circle, and the area of a circle is
pi×r²
remember, the radius is half the diameter.
so, in our case, the volume is
pi×(18/2)²×20 = pi×9²×20 = pi×81×20 = pi×1620 =

Using perfect squares simplification, it is found that the value of the desired limit is of -4.
When is a limit?It is the value of a function as x approach
In this problem, the limit we want to find is given by:
[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2}[/tex]
If we just replace x by -2, we end with an undetermined limit, as we have 0/0.
However, the perfect square simplification states that:
a² - b² = (a - b)(a + b).
Hence:
x² - 4 = (x + 2)(x - 2).
Then:
[tex]\lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2} = \lim_{x \rightarrow -2} \frac{(x + 2)(x - 2)}{x + 2} = \lim_{x \rightarrow -2} x - 2 = -2 - 2 = -4[/tex]
Hence, the value of the desired limit is of -4.

The bones at the time they were discovered when the radioactive element carbon-14 has a half-life of total 5750 years are 10062.5-year-old.
What is half-lives?Half lives is the time interval which is need to decay the atomic nuclei of a radioactive sample.
There is a scientist who determined that the bones from a mastodon had lost 70.3% of their carbon-14. Thus, the fraction remaining is,
f=1-(70.3/100)=1-0.703
f=1-(70.3/100)=0.297
Now the fraction remaining can be given as,
f=(1/2)ⁿ
Here, n is the half life elapsed. Put the value of fraction remaining.
0.297=(1/2)ⁿ
n=1.75
The radioactive element carbon-14 has a half-life of total 5750 years. Thus,
Years=1.75*5750
Years=10062.5
