The area of △ABC is A=1/2bh. The ______ can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the ________.
Choices: sin C=h/a, sin c=a/h, symmetric property of equality, transitive property of equality, substitution property of equality, associative property of equality, distributive property of equality, and commutative property of multiplication
Answer:
sin C=h/asubstitution property of equalitycommutative property of multiplicationStep-by-step explanation:
Because two points determine a line, you can draw altitude BD perpendicular to AC with height h. By the definition of a sine ratio, sin(C) = h/a, which can be rearranged into a·sin(C) = h. The area of △ABC is A=1/2bh. The substitution property of equality can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the commutative property of multiplication.
___
The mnemonic SOH CAH TOA reminds you that the sine ratio is ...
Sin = Opposite/Hypotenuse
Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...
sin(C) = h/a
__
The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:
1/2bh = 1/2ba·sin(C)
__
The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...
ba = ab
and
A = 1/2ba·sin(C) = 1/2ab·sin(C)

Step-by-step explanation:
A culture started with 1,000 bacteria. After 6
hours, it grew to 1,300 bacteria. Predict how
many bacteria will be present after 10 hours.
Round your answer to the nearest whole
number.
P = Aekt
Answer:
1350
Step-by-step explanation:
1000 to 1100 is an increase of 100 bacteria per 6 hours
100/6 = 16.67 bacteria per hour
16.67 * 15 hours = 250
Total bacteria should be 1100+250= 1350
hope this helps :D
Answer:
1,500 bacteria.
Step-by-step explanation:
I don't know what P=Aekt means but I understand the rest:
Hour 0: 1,000 bacteria
Hour 6: 1,300 bacteria
We can conclude from this evidence that it takes 6 hours to grow 300 new bacteria.
Let's use a ratio
new bacteria : hours
300 : 6
50 : 1
500 : 10
So we get 500 new bacteria after 10 hours. Using our original population of 1,000 and our new added members, we get 1,500 bacteria at Hour 10.

No dia 15/05/2020 as 18h e 40min o G1 divulgou que a Paraíba tem 3.739 casos confirmados e 170 mortes por coronavírus. Qual a porcentagem de mortos no Estado da Paraíba em relação a quantidade de casos confirmados ?
Answer:
4.55%
Step-by-step explanation:
To find the percentage of deaths in relation to the number of cases confirmed, we just need to divide the number of deaths by the number of cases confirmed.
So we have that:
Percentage = Deaths / Cases
Percentage = 170 / 3739
Percentage = 0.0455 = 4.55%
The percentage of deaths in relation to the number of cases is 4.55%
Find the value of in the triangle shown below.
Answer:
x= 6
Step-by-step explanation:
We can use the Pythagorean theorem to find x
x^2 + 2.5^2 = 6.5 ^2
x^2+ 6.25 =42.25
Subtract 6.25 from each side
x^2+ 6.25-6.25 =42.25-6.25
x^2 =36
Take the square root of each side
x = sqrt(36)
x= 6
Answer:
x=6
Step-by-step explanation:
This is a right triangle, because of the little square in the corner. Therefore, we can use the Pythagorean Theorem.
a^2+b^2=c^2
Where a and b are the legs and c is the hypotenuse.
In this triangle, we know that 2.5 and x are the legs, because they form the right angle. We know that 6.5 is the hypotenuse, because it is opposite the right angle.
Therefore, 2.5 and x are a and b, and 6.5 is c.
2.5^2+x^2=6.5^2
Evaluate the exponents
6.25+x^2=42.25
Since we are trying to find x, we have to get x by itself. First, subtract 6.25 from both sides
6.25-6.25+x^2=42.25-6.25
x^2=36
Next, take the square root of both sides, because x is being squared.
[tex]\sqrt{x^2}=\sqrt{36[/tex]
x=6
The area of rectangle ABDE is 270 square inches. The rectangle is rotated about a line that passes through points C and F. Rectangle A B D E has an area of 270 square inches. Point C is the midpoint of side D B and point F is the midpoint of side E A. The length of B A is 15 inches. Which best describes the resulting three-dimensional shape? a rectangular prism with an edge length of 9 inches a rectangular prism with an edge length of 18 inches a cylinder with a base radius of 9 inches a cylinder with a base radius of 18 inches
Answer:
The answer is C : a cylinder with a base radius of 9 inches
Step-by-step explanation:
The area is 270² inches, and to find the area of a rectangle is width × length . So the equation would be 270 = W × L, which would convert to 270 = W × 15 and 15 times 18 equals 270. But that is not thew answer because you would need top find the radius of the cylinder which is half of the width of the rectangle which means the radius is 9. So the answer is a cylinder with a base radius of 9 inches.
The resulting three dimensional shape is a cylinder with base radius 9 inches. Option c is correct.
A rectangle ABDE is given with area 270 inches and side AB =15 inches.
This rectangle is rotated about a line passes C and F where C and F is mid points of BD and EA respectively. The shape formed to be determine.
3D or three dimensions is define as when an object is an arbitrary space that its measure obtains on x, y and z axes.
Here,
Area of rectangle ABDE = 270
AB x BD = 270
15 x BD =270
BD = 270/15
BD = 18
Now C is mid point of BD so BC = 18/2
BC = 9
When the given rectangle rotate about CF the new 3d shape arise will be a cylinder with radius 9 inches.
Thus, the resulting three dimensional shape is a cylinder with base radius 9 inches.

Marta's dog just had six puppies. Four are female (F), and two are male (M). One of the males is brown. Two of the females are brown. All puppies are either brown or white. If Marta randomly gives away puppies to her friends, what is the probability of a friend getting a puppy that is male, brown, or both?
Answer:
Step-by-step explanation:
No of total brown = 2 + 1 = 3 .
probability = 3 / 6
= 1 /2 .
no of males = 2
probability
= 2 / 6
= 1 /3
no of person who is both male and brown = 1
probability = 1 /6
Required probability
= probability of being brown + probability of being male - probability of being both
= 1 / 2 + 1 / 3 - 1 /6
= 4 / 6
= 2 / 3 .
Final answer:
The probability of a friend getting a puppy that is male, brown, or both is 2/3, which is calculated by adding the probability of getting a male puppy and a brown puppy, then subtracting the probability of the overlap (brown male).
Explanation:
The student's question concerns the probability of a friend receiving a puppy that is male, brown, or both, given the conditions of the puppies provided. To calculate this probability, we consider all possible favorable outcomes divided by the total number of outcomes. There are 2 males (1 brown, 1 white) and 4 females (2 brown, 4 total), making a total of 6 puppies. A friend can receive either a male puppy (2 out of 6) or a brown puppy (3 out of 6, since we do not count the brown male twice). Thus, the probabilities need to be added together and the intersection (the brown male counted in both categories) subtracted to avoid overcounting.
We calculate the probability as P(Male) + P(Brown) - P(Brown and Male) = 2/6 + 3/6 - 1/6 = 4/6 or 2/3. Therefore, the probability of a friend getting a puppy that is male, brown, or both is 2/3.

Wanahton purified a portion of water with 900 grams of contaminants. Each hour, a third of the contaminants was filtered out.
Let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? Then, write an explicit formula for the sequence, g(n)=?
The sequence g(n) is a geometric sequence with an explicit formula of g(n) = (2/3)^n * 900 grams.
Explanation:The sequence g(n) represents the amount of contaminants (in grams) that remains at the beginning of the nth hour. Each hour, a third of the contaminants is filtered out. To determine whether g(n) is an arithmetic or geometric sequence, we need to examine the change in the amount of contaminants from one hour to the next.
Let's look at the first few terms of the sequence:
g(1) = 900 grams (initial amount)g(2) = 2/3 * g(1) = 2/3 * 900 gramsg(3) = 2/3 * g(2) = 2/3 * (2/3 * 900 grams)From the pattern, we can see that each term of g(n) is obtained by multiplying the previous term by 2/3. Therefore, g(n) is a geometric sequence.
The explicit formula for the sequence g(n) can be written as g(n) = (2/3)^n * 900 grams.

the minimum number of these pans that she needs in
order to make enough to feed 9 people?
Answer:
multiply it and add see if that's gives u the answer
Final answer:
Destiny needs to prepare at least 3 pans of her gelatin dessert to provide enough servings for 9 people, with each pan holding 8 servings.
Explanation:
Calculating the Minimum Number of Pans Needed
To find out the minimum number of pans Destiny needs to feed 9 people, we need to determine the total number of servings required and then see how many 8-serving pans will cover that need. Destiny plans 16 servings for every 6 people. So for 9 people, we calculate how many servings we would need using a simple proportion:
(16 servings / 6 people) = (x servings / 9 people)
Cross-multiply to solve for x: (16 servings × 9 people) = (x servings × 6 people)
144 servings = 6x servings
Divide both sides by 6: x = 24 servings
Destiny needs 24 servings for 9 people. Each pan holds 8 servings, so the number of pans needed is:
24 servings ÷ 8 servings per pan = 3 pans
Therefore, to make enough gelatin desserts to feed 9 people, Destiny needs at least 3 pans.

Please help me with this math problem. Find the equation for the line below.
Answer:
y+2=3/4(x+5)
Step-by-step explanation:
The first step is to find the slope of the line. Between the two points, the line rises from a y value of -2 to a y value of 4, or a total rise of 6 units. It also goes to the right from an x value of -5 to an x value of 3, which is a total of 8 units. 6 units of rise over 8 units of run is a total slope of 6/8=3/4. Now, you can use the point slope form for either one of the points (I'll use the leftmost one).
y+2=3/4(x+5)

One answer in point slope form: y + 2 = (3/4)(x + 5)
Answer in slope intercept form: y = (3/4)x + 7/4
Answer in standard form: 3x-4y = -7
===============================================
Explanation:
First we need the slope of the line
Find the slope of the line through (x1,y1) = (-5,-2) and (x2,y2) = (3,4)
m = (y2 - y1)/(x2 - x1)
m = (4 - (-2))/(3 - (-5))
m = (4 + 2)/(3 + 5)
m = 6/8
m = 3/4
-------
Plug m = 3/4 and (x1,y1) = (-5,-2) into the point slope formula. Solve for y.
y - y1 = m(x - x1)
y - (-2) = (3/4)(x - (-5))
y + 2 = (3/4)(x + 5)
y + 2 = (3/4)x + (3/4)*5 ... distribute
y + 2 = (3/4)*x + 15/4
y + 2 - 2 = (3/4)*x + 15/4 - 2 ... subtract 2 from both sides
y = (3/4)x + 15/4 - 8/4
y = (3/4)x + (15-8)/4
y = (3/4)x + 7/4
This equation is in slope intercept form y = mx+b
m = 3/4 is the slope, b = 7/4 is the y intercept
-------
Multiply both sides by 4 to help convert to standard form
y = (3/4)x + 7/4
4y = 3x+7
-7 = 3x-4y
3x-4y = -7
This is in the form Ax+By = C
A = 3, B = -4, C = -7

Write an equation that represents the line going through the points (-2, -11) and (2, -1) PLEASE HELP NOWWW
Answer:
y = (5/2)x - 6
Step-by-step explanation:
We need to use slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
Slope is the change in y divided by the change in x. Given the two points, we can find the difference in the y-coordinates and divide that by the difference in the x-coordinates:
m = (-11 - (-1)) / (-2 - 2) = -10 / (-4) = 5/2
Now, we have:
y = (5/2)x + b
Substitute one of the given points for x and y to solve for b:
-1 = (5/2) * 2 + b
-1 = 5 + b
b = -1 - 5 = -6
The answer is y = (5/2)x - 6.
Answer:
y = (5/2)x - 6
Step-by-step explanation:
Slope: (-1 - -11)/(2 - -2)
10/4
5/2
y = (5/2)x + c
-1 = (5/2)(2) + c
-1 = 5 + c
c = -6
y = (5/2)x - 6

Answer: 15%-8%=C
Step-by-step explanation:
Answer:
Well, you didnt include answers, but... here's the explanation.
Step-by-step explanation:
Ok so, the sale is 15% off. As an example, lets use $10 as the original price. 15% off of $10 = 1.5, so we subtract 10 - 1.5 = 8.5. Now, if the sale tax is 8%, we need to add 8% of 10, which is 0.8 - Now we get our final equation to calculate p, which is 8.5 + 0.8 = P. 8.5 + 0.8 = 9.3, and so the final price after discount AND sales tax are included is $9.3 - Hope this helped.
