Answer:
[tex]\sqrt[3]{27}[/tex]
Step-by-step explanation:
Let's split the cube root of 27 to make this easier:
[tex]\sqrt[3]{27}=\sqrt[3]{3\cdot9}=\sqrt[3]{3\cdot3\cdot3}\\\text{Now, let's put }3\cdot3\cdot3 \text{ in exponential form. We would have:}\\\sqrt[3]{3^3}\\\text{Now, the 3 and 3 and the square root symbol would cancel out, and we }\\\text{ would be left with 3. And since three is an integer, we know that} } \sqrt{27} \text{ is perfect }[/tex]

We see the two curved parts on the figure, this means those angles are congruent. That means x is congruent to that other angle.
We see the box type angle on the bottom. That is a right angle. It represents 90 degrees.
Pentagon's interior angles add up to be 540.
So, add them up together, equal to 540, and solve for x.
540 = 70 + x + x + 110 + 90.
540 = 260 + 2x
270 = 2x
135 = x.
The angle x is equal to 135.

RHS IS COT4A PLEASE SOLVE ITS URGENT
Answer:
Step-by-step explanation:
If the R.H.S. is cot(4A), given question is misprinted.
It should be,
[tex]\frac{1}{\text{tan3A+tanA}}-\frac{1}{\text{cot3A+cotA}}[/tex]
= [tex]\frac{1}{\text{tan3A+tanA}}-\frac{1}{{\frac{1}{\text{tan3A}}+\frac{1}{\text{tanA}}}}[/tex]
= [tex]\frac{1}{\text{tan3A+tanA}}-\frac{1}{\frac{\text{tanA+tan3A}}{\text{tanAtan3A}}}[/tex]
= [tex]\frac{1-\text{tanAtan3A}}{\text{tanA+tan3A}}[/tex]
= [tex]\frac{1}{\text{tan}(A+3A)}[/tex]
= cot(4A) [R.H.S.]
Hence proved.

Answer:
Step-by-step explanation:
First let's find the circle without the gray area. We would have:
[tex]\pi r^2=\pi 36^2=\pi1296[/tex]
Next let's find the area of the circle with the gray area. We would have:
[tex]\pi r^2=\pi50^2=\pi2500[/tex]
Now we subtract and get:
[tex](2500-1296)\pi=\boxed{1204\pi}[/tex]

Together Jason and Judy have read 24 mystery novels. Judy has read less than three times as many as Jason. How many mystery novels have each of them read.
Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason
Answer:Jason has read 7 mystery novels and Judy has read 17 mystery novels
Step-by-step explanation:
Total number of mystery books read by Jason and Judy =24
Let Number of mystery books read by Jason=x
and Number of mystery books read by Judy= 3x-4
So that the total number of book read by both of them will be expressed as
x +(3x-4) =24
x +3x-4 =24
4x=24+4
4x=28
x=28/4=7
There fore Jason has read 7 mystery novels
and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

Lakmini decided to measure the circumference of the Earth
using a very long tape measure. She held the tape measure
Im from the surface of the (perfectly spherical) Earth all the
way round. When she had finished her friend said that her
measurement gave too large an answer and suggested taking
off 6 m. Was her friend correct?
[Take the radius of the Earth to be 6400 km (if you need it).]
Answer:
Step-by-step explanation:
[tex]\Delta C=2\pi(r_2-r_1)\\ \\ \Delta C=2\pi(6400001-6400000)\\ \\ \Delta C=2\pi\\ \\ \Delta C\approx 6.283m\\ \\ \text{So taking off 6 meters is reasonable.}[/tex}

Ms. Hall wants to buy 30 fruit trees to plant on some land she just bought. She wants to plant only apple and peach trees. Each apple tree costs $22 and each peach tree costs $28. She has $720 to spend on trees.
Answer:
You would have to spend 674 dollars on trees if you only wanted to buy 30.
Step-by-step explanation:
22 times 15 = 264
28 times 15 = 420
Add them and you get 674
Adam can buy pencils in packages of 12 for $2.19, 40 for $3.99, 50 for $4.75, or 100 for $10. How many pencils are in the package with the lowest unit cost
Answer:
50 pencils
Step-by-step explanation:
2.19/12 = .18
3.99/40 = .09975
4.75/50 = .095
10/100 = .10
Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...
Answer:
50 for $4.75
Step-by-step explanation:
First step is to determine the unit cost of each pencil:
price of pack / number of units = cost per pencil
1. $2.19 / 12 = $0.1825
2. $3.99 / 40 = $0.09975
3. $4.75/ 50 = $0.095
4. $10 / 100 = $0.10
The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

Help Me Mr Thompson! HW For Math
Answers:
6) b. Apply square root to both sides7) d. 8 by 10. 8) a. Thickness of edge that leads to total area of 100 square inches9) a. x = -5 and x = 3/210) d. zero product property======================================================
Explanations:
6) We apply the square root to both sides to undo the squaring operation.7) The photo without the frame is 8 by 10 since we add on two copies of x to jump from 8 to 8+2x. Similarly, we go from 10 to 10+2x.8) The x represents the thickness of the frame. The 100 is the total area (picture + frame). The expression on the right hand side is also the total area.9) Apply the zero product property to set each factor equal to zero. You'll find that x+5 = 0 leads to x = -5. Also, 2x-3 = 0 becomes 2x = 3 and solves ultimately to x = 3/210) Refer to problem 9HELP ME PLEASE 10 points!!!!!
tamika has $55 in her savings account. She plans on depostiting $5 per week into her account. Write and solve an inqequality to find out how many weeks she must save to have more than $100 in her account. Then interpet the solution
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
55+5x>1005x>100-55 (Subtract 55 from each side)5x>45x>9 (Divide each side by 5)This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.

Answer:
x= a10
Step-by-step explanation:
in this figure prove that cd//ef
Answer:
1) 36 + 50 = 86 : Addition property of equality
2) m<D = m<ADB : If two angles have the same measure, then they are equal.
3) <D congruent to <ADB : if two angle are equal, then they are congruent.
4) <D, <ADB are alternate interior angles: assumed from diagram
5) CD // AB : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.
6) 130 + 50 = 180 : addition property of equality
7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.
8) <E, <BAE are same-side interior angles : assumed from diagram
9) EF // AB : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.
10) CD // EF : if two lines are // to the same line, then they are //.
im pretty sure this is the proof
