Use the triangle pictured to calculate the following measurements.
Perimeter: p = ___ units Semiperimeter: s = ___units Area: A ≈ ___square
triangle is 8 by 12 by 10
Answers
The perimeter of the triangle is the sum of its sides.
We have then:
P = 8 + 12 + 10
P = 30 units
Semi-perimeter:
In geometry, the semiperimeter of a polygon is half its perimeter.
s = P / 2
s = 30/2
s = 15 units.
Area:
Knowing the semiperimeter and the sides, the area is:
A = root (s * (s-a) * (s-b) * (s-c))
where,
s: semi-meter
a, b, c are sides.
A = root (15 * (15-8) * (15-12) * (15-10))
A = 39.68626967

The formula v =bh means that the volume of a prism is equal to its base area times its height. Solve v= bh for b
Answers
Answer:
[tex]b = \frac{v}{h}[/tex]
Step-by-step explanation:
The formula v =bh means that the volume of a prism is equal to its base area times its height.
WE need to solve for b, we need to get 'b' alone
v=bh
to get 'b' alone we need to eliminate 'h'
To eliminate any variable we always do opposite operation.'
bh mean b times h
the opposite of multiplication is division
so to eliminate 'h' we divide by 'h' on both sides
[tex]\frac{v}{h} = \frac{bh}{h}[/tex]
[tex]b = \frac{v}{h}[/tex]
The formula for the base area (b) of a prism is b = v/h.
To solve the formula v = bh for b (the base area), to isolate b on one side of the equation. Follow these steps:
Divide both sides of the equation by h:
v/h = b
The base area (b) is now isolated on one side of the equation.

Answers
For example, 2+3 is a math expression
To make it an algebraic expression, we replace one of the numbers with a variable. Often this is the letter x. So let's say we replace the 2 with x. That would have the expression turn into x+3. What we're saying is "some number plus 3"
Normally 2+3 = 5 which is a true equation. Replace the 2 with x and we have x+3 = 5. So we're saying "some number plus 3 is 5". You can guess and check to find that the "some number" has to be 2
--------------------------------------
In summary, the expression example was x+3 and the equation was x+3 = 5

They are two equivalent fractions that can describe the last of the juice boxes that is grape.
If you need me to explain, comment something
Final answer:
Javier has 4 juice boxes, 3 of which are grape flavored. The fraction representing grape juice boxes is 3/4, with equivalent fractions being 6/8 and 9/12.
Explanation:
Javier has 4 juice boxes and three are grape flavored. To describe the part of the juice boxes that is grape in the form of a fraction, we would use the total number of juice boxes as the denominator and the number of grape juice boxes as the numerator. So, the fraction representing the grape juice boxes is 3/4 (three out of four).
To write two equivalent fractions, we can multiply the numerator and the denominator by the same number. If we multiply both by 2, we get 6/8, which is equivalent to 3/4. Similarly, multiplying both by 3 gives us 9/12, which is also equivalent to 3/4.

April is randomly choosing five CDs to bring in her car from the following: 6 pop CDs, 8 rock CDs, and 10 R&B CDs. What is the complement of April choosing five pop CDs? choosing five CDs where none of them are pop choosing five CDs where not all of them are pop choosing five CDs where at least one of them is pop choosing five CDs where all of them are pop
Answers
Answer:
choosing five CDs where not all of them are pop
Step-by-step explanation:
The complement of an event is everything possible except that event. It is found by subtracting the probability of an event from 1.
The event we have listed is April choosing 5 pop CDs. The complement would literally be read as "not choosing 5 pop CDs." This means she would choose 5 CDs, where some could possibly be pop, but others would not.
Using the concept of complementary events, it is found that the complement of April choosing five pop CDs is given by:
choosing five CDs where not all of them are pop.
What are complementary events?Two events are complementary if the sum of their probabilities is of 1.
For example, either you choose five pop CDs, or you do not choose five pop CDs.
Hence the complement of this event is given by not choosing five pop CDs, that is:
choosing five CDs where not all of them are pop.

Step-by-step explanation:It is given that:
Margo has a coin collection.
She was given 1 coin as a gift, and she adds 3 coins per year.
i.e. she started with a initial of one coin and add 3 coins each year.
That is this situation can be represented with the help of a function:
C(t) which represents the number of coins she has in 't' years.
Now,
C(0)=1
Also,
C(t)=3t+1-------------(A)

a)
it is given that:
Graph passes through (1,2) and (3,4)
i.e. when t=1 C(t)=2
and when t=3 C(t)=4
but on putting the value of t in equation (A) it does not hold true.
same could be done for option (b) and option (d).
But in option (c)
It hold true.
c. graph of line going through 1, 4 and 3, 10Since,
when t=1
C(t)=3×1+1=4
when t=3
C(t)=3×3+1=10
Hence, the correct answer is:
c.) graph of line going through 1, 4 and 3, 10
Is it possible to place 158 books on three shelves so that the first shelf has 8 fewer books than the second and 5 more books than the third shelf?
plz halp
Answers
We are given 158 books to place them on three different shelves like A, B, and C.
It says that shelf A has eight fewer books than shelf B and five more books than shelf C.
Mathematically, it can be written as (A = B - 8) and (A = C + 5).
Or we can write it as (B = A + 8) and (C = A - 5).
If we consider there are 'x' books in shelf A, then shelf B would have 'x+8' books and shelf C would have 'x-5' books.
We know that Total books are 158, so its sum must be equal to total books.
A + B + C = 158
x + (x+8) + (x-5) = 158
3x + 3 = 158
3x + 3 - 3 = 158 - 3
3x = 155
[tex] \frac{3x}{3} =\frac{155}{3} [/tex]
x = 51.667 books
But 'x' must be an integer value because number of books can not be a decimal form.

What are the angle measures of the triangle 6 12 6sqrt3?
Answers
Answer:
The measure of angle A is 30 degree, measure of angle B is 90 degree and measure of angle C is 60 degree.
Step-by-step explanation:
The measures of given sides are 6, 12, [tex]6\sqrt{3}[/tex].
According to the Law of Cosine:
[tex]\cos A=\frac{b^2+c^2-a^2}{2bc}[/tex]
Using Law of Cosine, we get
[tex]\cos A=\frac{(12)^2+(6\sqrt{3})^2-(6)^2}{2(12)(6\sqrt{3})}[/tex]
[tex]\cos A=\frac{216}{144\sqrt{3}}[/tex]
[tex]\cos A=\frac{3}{2\sqrt{3}}[/tex]
[tex]\cos A=\frac{\sqrt{3}{2}[/tex]
[tex]A=30^{\circ}[/tex]
Similarly,
[tex]\cos B=\frac{a^2+c^2-b^2}{2ac}[/tex]
[tex]\cos B=\frac{(6)^2+(6\sqrt{3})^2-(12)^2}{2(6)(6\sqrt{3})}[/tex]
[tex]\cos B=\frac{0}{36\sqrt{3}}[/tex]
[tex]\cos B=0[/tex]
[tex]B=90^{\circ}[/tex]
Therefore, measure of angle A is 30 degree and measure of angle B is 90 degree.
According to angle sum property, the sum of interior angles of a triangle is 180 degree.
[tex]A+B+C=180^{\circ}[/tex]
[tex]30^{\circ}+90^{\circ}+C=180^{\circ}[/tex]
[tex]C=60^{\circ}[/tex]
Therefore the measure of angle C is 60 degree.
The triangle with sides 6, 12, and 6√3 has angles of 30 degrees, 60 degrees, and 90 degrees.
Given a triangle with sides 6, 12, and 6√3, we can find the angles using the Law of Cosines.
First, we use the formula for the Law of Cosines,
c² = a² + b² - 2ab * cos(C).
Let a = 6, b = 6√3, and c = 12.
We substitute these values into the formula to find angle C,
cos(C) = (6² + (6√3)² - 12²) / (2 * 6 * 6√3)
Compute the values inside the formula:
6² = 36
(6√3)² = 108
12² = 144
cos(C) = (36 + 108 - 144) / 72
cos(C) = 0
Therefore, angle C = 90 degrees.
To find the other angles, we use the Law of Sines,
(sin A / a) = (sin B / b) = (sin C / c).
We already know C = 90°, so (sin C / 12) = 1/12.
For angle A,
sin(A) / 6 = 1/12
sin(A) = 6/12 = 1/2
A = 30 degrees
For angle B:
B = 180° - 90° - 30° = 60 degrees
Therefore, the angles of the triangle are 30 degrees, 60 degrees, and 90 degrees.

Step-by-step explanation:
Given :
On a softball field, home plate is 43 feet from the pitcher’s mound.
A ball is hit at an angle of 27° east of the pitcher’s mound.
The ball travels 162 feet before it is caught by an outfielder.
To Find : Rounded to the nearest foot, the outfielder must throw the ball feet to return it to the pitcher.
Solution:
Law of cosines: [tex]a^2 = b^2 + c^2 -2bc cos A[/tex]
∠A = 27°
b = 43
c = 162
Substitute the given values
[tex]a^2 = 43^2 + 162^2 -2(43)(162) cos 27^{\circ}[/tex]
[tex]a^2 = 15679.497105[/tex]
[tex]a = \sqrt{15679.497105}[/tex]

Final answer:
The function y = 8700(1.04)^4 represents an exponential growth with a rate of increase of 4% per time period over four periods.
Explanation:
The given function is y = 8700(1.04)^4. This represents an exponential growth because the base of the exponent, 1.04, is greater than 1. To determine the percentage rate of increase, we observe that the base, 1.04, when written as a percentage, is 104%. This means that the amount increases by 4% over each time periodperiod. Since the exponent is 4, this growth occurs over four time periods. However, the overall increase is not simply 4% multiplied by 4, as exponential growth compounds wicompoundsth each time period.
