Area of triangle = 1/2×base×height
= 1/2×32×18
= 288in²
which sides form a right triangle
Answer:
c
Do i get brainliest lol
Responda: Por favor, é urgente.
Answer:
C) CA=40
Step-by-step explanation:
2y/(2y+4)=(2y+6)/4y
cross multiply
8y²=4y²+20y+24
4(2y²)=4(y²+5y+6)
divide both sides by 4
2y²=y²+5y+6
y²-5y-6=0
(y-6)(y+1)=0
So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.
CA=2(6)+4+4(6)
CA=12+4+24
CA=40

Answer:
12 square inches
Step-by-step explanation:
The area is given by the formula ...
A = 1/2bh
Here, the base is 6 inches and the height is given as 4 inches. Then the area is ...
A = (1/2)(6 in)(4 in) = 12 in²
The area of the triangle is 12 square inches.

Comment on the problem
Since you are given the base and height, we presume you are intended to use the formula above. You are also given all three side lengths. If you use the appropriate formula with those, you find the area is about 15.6 square inches. (The height of this triangle is actually closer to 5.2 inches.)
The figure represents a geometry that cannot exist. With the given base and height, the side lengths should be 5, not 6.

11. Twelve samples of water form a particular source have an average lead concentration of 12.5µg/L with a standard deviation of 2.0µg/L. 1 (a) Find a 95% confidence interval for the lead concentration in water from this source. (b) Can you conclude that the lead concentration is less than 14µg/L?
Answer:
a) The 95% confidence interval for the lead concentration in water from this source is between 11.23 µg/L and 13.77 µg/L.
b) The upper bound of the confidence interval is less than 14 µg/L, which means that yes, we can conclude that the lead concentration is less than 14µg/L.
Step-by-step explanation:
We have the standard deviation for the samples, which mean that the t-distribution will be used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 12 - 1 = 11
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 11 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.201
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.201\frac{2}{\sqrt{12}} = 1.27[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 12.5 - 1.27 = 11.23 µg/L.
The upper end of the interval is the sample mean added to M. So it is 12.5 + 1.27 = 13.77 µg/L.
The 95% confidence interval for the lead concentration in water from this source is between 11.23 µg/L and 13.77 µg/L.
(b) Can you conclude that the lead concentration is less than 14µg/L?
The upper bound of the confidence interval is less than 14 µg/L, which means that yes, we can conclude that the lead concentration is less than 14µg/L.
In a walking competition, Marlinda was 15m ahead of Sandra Evliani. Marlinda steps 1m each time Sandra Elviani’s foot steps 0.8m. How many steps does Sandra Elviani have to make to match Marlinda?
Answer:
Given that in a walking competition, Marlinda was 15m ahead of Sandra Evliani, and Marlinda steps 1m each time Sandra Elviani's foot steps 0.8m, to determine how many steps does Sandra Elviani have to make to match Marlinda, the following calculation must be performed:
Since Sandra Elviani walks 0.8 meters for every 1 meter that Marlinda walks, and that she has an advantage of 15 meters in the competition, it is impossible that at that rate Sandra can reach her. This is so because for each step of Marlinda, Sandra will be 0.2 meters behind her, increasing the distance (1-0.8).

Each figure below represents a fraction. Which figure is NOT equivalent to the others
The full question with the answer options is as follows:
Each figure below represents a fraction. Which figure is NOT equivalent to the others?
the answer options are as follows:
a. [tex]\frac{2}{3}[/tex]
b. [tex]\frac{4}{6}[/tex]
c. [tex]\frac{3}{4}[/tex]
d. [tex]\frac{8}{12}[/tex]
Answer:
The correct answer is c:
Step-by-step explanation:
To know when two or more fractions are equivalent, we must multiply the numerator of one fraction by the denominator of the other fraction, the result must be the same value.
[tex]\frac{2}{3} x \frac{4}{6}[/tex] = (2x6) =12 ; (3x4)=12
[tex]\frac{2}{3} x \frac{8}{12}[/tex] = (2x12)=24 ; (3x8) =24
[tex]\frac{4}{6} x \frac{8}{12}[/tex] = (4x12)=48; (6x8)=48

Hi can someone please help me with this question I've been stuck on it for soooo long!!
Answer:
Let x=sinθ
2sin²θ = 5sinθ - 3
2x²=5x-3
2x²-5x+3=0
(2x-3)(x-1)=0
2x-3=0 or x-1=0
x=3/2 or x=1
sinθ=2/3 or sinθ=1
θ=arcsin(2/3) or θ=arcsin(1)
θ=0.729727656 or θ=1.57079633=π/2

Kriti has 20 coins that make up a total of 41 in the denomination of 1-rupee, 2-rupee, and 5-rupee coins.
The number of 2-rupee coins are three times the number of 5-rupee coins.
Answer:
8
Step-by-step explanation:
Let us assume the following things
x be no of 5 rupees coins
y be no of 2 rupees coins
z be no of 1 rupees coins
Now accoridng to the question
5x + 2y + z = 41
x + y + z = 20
y = 3x
Now do the elimination of variables
So,
4x + y = 21
7x= 21
x = 3
y = 9
z= 8
hence, the 1-rupee coin would be 8
x = _

Mike, a local auto mechanic, charges a certain amount to diagnose and repair a car. He bases his price on the amount of time that it takes for the repair. Use the graph shown below to fill out the missing representations. Then, answer the questions that follow.
Can you also answer questions and 2 at the bottom.
Answer:
Okay ill do it from the ones given
Verbal Description:
Well it seems like Mike is charging a one time fee of 50 dollars each no matter what and after that its 30 dollars per hour.
Equation:
Assuming X is hours and C is total cost
50+30x= C
Table: (this will be in the order of hours, process and total)
0- (50+30*0) -0
1- (50+30*1) -80
2- (50+30*2) -110
3- (50+30*3) -140
4- (50+30*4) -170
5- (50+30*5) -200
6- (50+30*6) -230
Graph:
There are no instructions or questions for graph but if there is let me know in the comments
Questions:
#1) The rate of change for the graph is 30 dollars per hour or 30/1. Since for every hour its +30 plus the one time fee.
#2) The y-intercept here is 50 or in this case the one time payment fee.
