Step-by-step explanation:
She first catches 54 and returns them then she catches 70 and 13 of those she had previously caught, so she only caught 57 new frogs. So within the sample time period she had caught a total of 54+57= 111 frogs.
Answer: 111
Step-by-step explanation:
she catches 54 and puts on the leg bands. The next day she catches 70 but 13 of them were from the previous day.
So, 54+70-13=111

sine rule and area of any triangle
find area of this triangle to 1 decimal place please
I got 61.1 as the answer but it's wrong apparently
thanks
Answer:
94.1 m²
Step-by-step explanation:
Use the sine rule to find BC
[tex]\frac{BC}{sin82}[/tex] = [tex]\frac{12}{sin40}[/tex] ( cross- multiply )
BC × sin40° = 12 × sin82° ( divide both sides by sin40° )
BC = [tex]\frac{12sin82}{sin40}[/tex] ≈ 18.487
Area = [tex]\frac{1}{2}[/tex] × 12 × 18.487 × sin58° ≈ 94.1

y = 24
Step-by-step explanation:
The general equation of a direct variation is
y = k x
In this case
x = 10
y = 16
y = k*x
16 = 10*k
16/10 = k
k = 1.6
y = 1.6x

Answer:
2.150 = 2.15
2 +15/10 > 2.15
2 + 0.015 < 2.15
215/100 = 2.15
Step-by-step explanation:
2.150 = 2.15, because 2.15 can be rewritten as 2.150.
2 +15/10=2+1.5=3.5
2 +15/10 > 2.15
3.5 > 2.15
2 + 0.015 < 2.15
2.015 < 2.15

if a frog can move 1/4 of a mile every hour, then how many hours would it take for a frog to go 2 miles?
Answer: 8 hours
Step-by-step explanation: If a frog can jump 1/4 fourth a mile every hour then it will take 4 hours to complete a mile. But because we are talking a bout 2 miles, you have to double the time. Therefore, the answer is 8 hours
It would be one hour every quarter of the mile so count the hours by the amount of numbers there are in one mile so it would be 8 hours
Rico is offered a permanent position that pays $45,000 a year. The same week, Rico is offered a full-time (8 hour days, 5 days a week) job that pays $20.50 an hour. Based on the monthly income of each job, which would you recommend to Rico and why?
Answer:
I recommend the work that pays $45,000 a year because the monthly income is greater than the other job
Step-by-step explanation:
we know that
The first work pays $45,000 a year
so
The monthly income is equal to
$45,000/12=$3,750 per month
The second work pays $20.50 an hour
Remember that
1 year= 52 weeks
so
In one year pays -----> (8)*(5)*(52)($20.50)=$42,640 a year
The monthly income is equal to
$42,640/12=$3,553.33 per month
I recommend the work that pays $45,000 a year because the monthly income is greater than the other job
How to find the area of a triangle on a coordinate plane
Equation of Area of Triangle = 1/2 x b x h
Find the base by counting the boxes across the bottom.
Find the height by counting the boxes from the base (bottom) to highest point on the triangle.
Insert those numbers into the equation and you get your answer.
To find the area of a triangle on a coordinate plane, you can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
Explanation:To find the area of a triangle on a coordinate plane, we can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
For example, if the coordinates of the vertices are (x1, y1), (x2, y2), and (x3, y3), we can find the length of the base by calculating the distance between (x1, y1) and (x2, y2). Then, we can find the height by calculating the distance between (x3, y3) and the line containing the base. Finally, we substitute the values of the base and height into the formula to find the area.
Suppose the coordinates of the triangle are (1, 2), (4, 6), and (7, 2). We can find the base and height as follows:
Base: Distance between (1, 2) and (4, 6) = sqrt((4 - 1)^2 + (6 - 2)^2) = sqrt(9 + 16) = sqrt(25) = 5 unitsHeight: Distance from (7, 2) to the line containing the base (1, 2) and (4, 6) = perpendicular distance from (7, 2) to the line = 2 units (since the line is parallel to the x-axis)Now, substitute the values into the formula: Area = 1/2 * base * height = 1/2 * 5 * 2 = 5 units^2. Therefore, the area of the triangle is 5 square units.

Answer:
118°
Step-by-step explanation:
Since it is an isosceles triangle, two angles must be the same.
Also angles in a triangle add up to 180° and from this we can deduce that
x + ( 31 + 31 ) = 180
( Simplify )
x + 62 = 180
( - 62 from both sides )
x = 118°

which expressions are equivalent to the log8 1 * log3 27. check all that apply.
a - 3 * 8
b - 3 * log8 8
c - 1
d - 0
Answer:
It's d. 0.
Step-by-step explanation:
The log (to any base) of 1 = 0, so log8 1 = 0, and the whole expression is equal to 0:
0 * log3 27 = 0.
The expression log8 1 * log3 27 evaluates to 0, so the equivalent expression from the options is d - 0.
Explanation:The expressions we need to evaluate are log8 1 * log3 27. The log of 1, no matter what the base, is always 0. This is because any number raised to the power of 0 is 1. So, log8 1 is equal to 0. Now, evaluate log3 27. The log base 3 of 27 is 3 because 3 cubed (or 3 to the power of 3) is 27. So, log3 27 equals 3. Thus, log8 1 * log3 27 = 0 * 3 = 0. Comparing with the given options, we find that the only equivalent expression is option d - 0.

What is the equation of the midline for the function y = 3cos(x - π ) - 4?
y = -4
y = -π
y = 4
y = π
Answer:
The correct answer option is y = -4.
Step-by-step explanation:
We are to find the equation of the mid-line for the following function:
[tex]y=3cos(x-\pi)-4[/tex]
[tex]3 cos((x - \pi ) - 4 = 3 cos(x) - 4[/tex] because [tex]cos(x-\pi) = cos(x)[/tex]
[tex]-1 \leq cos(x) \leq 1[/tex]
[tex]-3 \leq 3cos(x) \leq 3[/tex]
[tex]-3-4 \leq 3 cos(x)-4 \leq 3-4[/tex]
[tex]-7 \leq 3 cos(x)\leq-1[/tex]
The range is -7 to -1 so the midpoint is [tex]\frac{-7-1}{2} =-4[/tex]
Therefore, the equation of the mid-line for the given function is y = -4.
What value of x would make the expression below equal to 8? Photo provided! 20points!
For this case, we must find the value of "x" so that the given expression is equal to 8.
That is to say:
[tex](\sqrt [5] {8 ^ 3}) ^ x = 8[/tex]
We apply "ln" to both sides of the equation to remove the exponent variable:
[tex]ln ((\sqrt [5] {8 ^ 3}) ^ x) = ln (8)\\xln (\sqrt [5] {8 ^ 3}) = ln (8)\\xln (\sqrt [5] {512}) = ln (8)[/tex]
We rewrite 512 as:
[tex]512 = 32 * 16 = 2 ^ 5 * 16\\xln (\sqrt [5] {2 ^ 5 * 16}) = ln (8)[/tex]
By definition of power properties we have:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
So:
[tex]xln (2 \sqrt [5] {16}) = ln (8)[/tex]
We clear x:
[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}[/tex]

Samara is adjusting a satellite because she finds it is not focusing the incoming radio waves perfectly. The shape of her satellite can be modeled by y^2=2(x+6), where x and y are modeled in inches. She realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?
Answer:
(-5.5,0)
Step-by-step explanation:
The question is on finding the focus point of a parabola
Given y²= 2(x+6).....................................(a)
Compare equation (a) with the standard equation (y-b)²= 2p(x-a)
y²= 2(x+6)------can be written as (y-0)²=2(x+6)
(y-0)²=2(x+6)
(y-b)²= 2p(x-a)
2p=2-----------------divide both sides by 2 to get p
p=2/2=1
For the vertex (a,b)⇒(-6,0)
For the focus point ( a+p/2, b)........................................(b)
Substitute values i equation (b) above
(-6+1/2 ,0) =(-5.5, 0)
