Answer:
Step-by-step explanation:
nth root of a number 'a' is represented by the expression,
[tex]\sqrt[n]{a}[/tex]
In this expression 'n' = Index of of the radical
[tex]\sqrt[4]{16}[/tex] is called the 4th root of 16.
In [tex]\sqrt[4]{16}[/tex], the index is 4 and the radicand is 16.
4th root of 16 can be represented by [tex]\sqrt[4]{16}[/tex]
[tex]\sqrt[4]{16}=(16)^{\frac{1}{4}}[/tex]
[tex]=(2^{4})^{\frac{1}{4}}[/tex]

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?
Answer: 720
Step-by-step explanation:
From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.
If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:
1/20 × x = 36
x/20 = 36
x = 20 × 36
x = 720
The turtle population is 720

A bird feeder is in the shape of a cylinder. It has a volume of about 100 cubic inches. It has a radius of 2 inches. What is the approximate height of the bird feeder? Use 314 for pi.
Answer:
8 in approx
Step-by-step explanation:
Given data
volume = 100 cubic inches
radius= 2 inches
The expression for the volume of a cylinder is given as
v=πr^2h
substitute
100= 3.14*2^2h
100= 12.56h
h= 100/12.56
h=7.9 in
Hence the height is 8in approx
Throughout Lewis Carroll's book, Alice's Adventures in Wonderland, Alice's size changes. Her normal height is about 50 inches tall. She comes across a door, about 15 inches high, that leads to a garden. After drinking a potion, Alice's height changes to 10 inches so she can visit the garden. How tall would the door have been in Alice's normal world? Justify your answer and provide mathematical evidence.
Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
Raju’s age (in years) is 2 more than 5 times her daughter’s age. What is his age. guys help me
Step-by-step explanation:
if you are writing it in an expression then
let raju's age be = x
let daughter be = y
x = 2 (5 × y)
x = 2 (5y)
x = 10y
so if daughter is 2 years old, then
x = 10(2)
x = 20 years

Answer:
1. The applicable theorem is the midsegment theorem
y = 5 cm
Step-by-step explanation:
The given quadrilateral MATH is an isosceles trapezoid,
The bases of the isosceles trapezoid are
b₁ = [tex]\overline{MA}[/tex] and b₂ = [tex]\overline{HT}[/tex]
The median of the isosceles trapezoid = [tex]\overline{LV}[/tex]
MA = 3·y - 2
HT = 2·y + 4
LV = 8.5 cm
The midsegment theorem states that the median of a trapezoid is parallel to the bases of the trapezoid and is equal to half the length of the sum of the bases of the trapezoid
The median of a trapezoid = (1/2)×(b₁ + b₂)
Therefore, we have;
The median of the isosceles trapezoid, LV, given as follows;
LV = 8.5 = (1/2)×((3·y - 2) + (2·y + 4))
LV = 8.5 = (1/2)×(5·y + 2) =
2 × 8.5 = (5·y + 2)
17 = 5·y + 2
∴ 5·y = 17 - 2 = 15
y = 15/3 = 5
y = 5 cm

71+42+BAD=180
BAD=67
Answer:
m<BAD = 67
Step-by-step explanation:
The given figure is a parallelogram. Consecutive angles in a parallelogram are supplementary, meaning that their angle measures sum up to 180 degrees. Using this, one can say,
m<D + m<A = 180
Substitute,
m<ADB + m<BDC + m<A = 180
71 + 42 + m<A = 180
113 + m<A = 180
Inverse operations,
113 + m<A = 180
-113 -113
m<A = 67

4. Suppose 4x + 9 pizzas were sold on Monday and 3x - 4 pizzas were sold on
Tuesday. What is the total number of pizzas sold?
Answer:
7x+5 pizzas were sold.
Step-by-step explanation:
4x and 3x combine to make 7x. Since we are adding 9 and also subtracting 4, they cancel out to be adding only 5. Combine this to make 7x+5.
Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.
Answer:
there are infinitely many solutions
LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).
Once you do that, you will notice that both sides/both equations are exactly the same.
Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.
The answer is: "There are infinetly many solutions"
Work out (4.2×107)÷(7×104)Give your answer in standard form. Work out (4.2×107)÷(7×104)Give your answer in standard form.
Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

Given the parent function p(x) = cos x, which
phrase best describes the transformation used
to obtain the graph of g(x) = cos (x + a) – b,
if a and b are positive constants?
Answer: left a units, down b units
Step-by-step explanation:
The phrase which describe g(x) for parents function p(x) is:
" Graph shifts a units in negative x direction and b units in negative y direction"
What is Shifting of Origin?The shifted origin has the coordinates (h, k). That is, the shifted X and Y axes are at distances h and k from the original X and Y axes respectively.
Here, general equation
y = cos ( x - h ) + k
where, h and k are points which shows the shifting of function on x and y axes.
On comparing general equation with given equation g(x)
so we get h = -a and k = -b.
Thus, the phrase which describe g(x) for parents function p(x) is:
" Graph shifts a units in negative x direction and b units in negative y direction".

What is another way to write 15 divided by 2?
15
O 15+2
O 15 x 2
Answer: [tex]15\times\frac{1}{2}[/tex]
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]
The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]
