Bryce measured the circumference of a tree trunk. Its circumference was 91 ft. What was the approximate diameter, rounded to the nearest foot?
Answer: 29 feet.
Step-by-step explanation: The formula for the circumference of a circle is C = π d. In order to calculate the diameter of the tree we will use the same formula and solve for d.
91 = 3.14 x d
In order to solve for d you need to divide both sides for 3.14:
D = 28.98, rounded to the nearest foot is 29 feet.

The angles at the left and right tips of the kite are right angles. The length of the long, diagonal brace of this kite is 100 cm. The length of the shorter side of the kite is 60 cm. What is the length of the longer side of the kite?
A. √13600
B. 40
C. 80
D. 1600
(sorry if the symbol for choice A. is wrong)
ANSWER
C. 80
EXPLANATION
The longer diagonal is serving as the hypotenuse of the right triangles.
Let the longer side of the kite be x cm.
Then, from the Pythagoras Theorem, the sum of the length of the squares of the two shorter legs equals the square of the hypotenuse.
This means that,
[tex] {x}^{2} + {60}^{2} = {100}^{2} [/tex]
[tex] {x}^{2} + 3600 = 10000[/tex]
[tex] {x}^{2} = 10000 - 3600[/tex]
[tex] {x}^{2} = 6400[/tex]
[tex]x = \sqrt{6400} [/tex]
[tex]x = 80cm[/tex]

6–[(−3)+(−7)]–[(−1)–(−5)–(−8)]
Answer:
4
Step-by-step explanation:
Here's all the steps, let's just remove all this confusing garbage with the adding negatives first.
6-(-3-7)-(-1+5+8)
Remember, subtracting a negative makes it positive.
6-(-10)-(12)
6+10-12
16-12
4
The expression 6–[(−3)+(−7)]–[(−1)–(−5)–(−8)] simplifies to 2 after solving the operations inside the brackets and applying the order of operations correctly.
The question asks to simplify the expression 6–[(−3)+(−7)]–[(−1)–(−5)–(−8)]. Let's break it down step by step.
Simplify inside the first brackets: (−3)+(−7) = −10.Simplify inside the second brackets: (−1)–(−5)–(−8) = 1+5+8 = 14.Substitute these values back into the original expression: 6 – (−10) – 14.Remembering that subtracting a negative is the same as adding its positive value: 6 + 10 – 14 = 16 – 14.Finally, subtract: 16 – 14 = 2.Therefore, the simplified expression is 2.
Chris pays a fee if her bank balance falls below $10 on the statement date, her balance was -$3.46. Then, Chris made a deposit, d, in ample time, so she did not have to pay a fee. Write an inequality to represent this situation. Then solve the inequality. Describe the meaning of the solution.
If her balance is below 10, Chris must pay a few.
b = balance
Her balance was -$3.46. Then, Chris made a deposit, d, in ample time, so she did not have to pay a fee.
b + d > 10
b = -3.46
Inequality: -3.46 + d > 10d > 10 - -3.46
Solved: d > 13.46Meaning: The amount that Chris deposits has to increase her balance, so that it's not less than $10.Based on the information you provided, we can write an inequality to represent the situation. Chris's balance was -$3.46 and she made a deposit of d dollars. To avoid paying a fee, her balance must be greater than or equal to $10 on the statement date. So the inequality is: -3.46 + d >= 10. Solving for d, we get d >= 13.46. So Chris must have deposited at least $13.46 to avoid paying a fee.

joby had $421.56 in her checking account when she deposited g $20 bills and k quarters. Write an expression that represents the amount of money in her account after the deposit.
Answer: [tex]421.56+20g+\frac{k}{4}[/tex]
Step-by-step explanation:
You have the following information given in the problem above:
- She had $421.56 in her checking account.
- She she deposited g $20 bills (which you can rewrite: [tex]20g[/tex]) and k quarters (which you can rewrite as folllowing:[tex]\frac{k}{4}[/tex]).
Therefore, the amount of money in her account after the deposit is the sum of the amoun she had in her account plus the amoun of money she deposited.
Then, you can write the following expression:
[tex]421.56+20g+\frac{k}{4}[/tex]
Answer:
421.56 + 20g + 1/4 k
Step-by-step explanation:
Joby had $421.56, and she deposited g $20 bills, and k quarter:
We don´t know how many $20 bills she deposited but we know it is expressed by the letter g, so she deposited $20g, and we add to that how many quarters of a dollar she added, in this case, we know that she deposited k quarters or 1/4 k dollars.
To write an expression to know the amount of money she has after the deposit we have to add:
What she had before the deposit = $421.56
The Dollars in $20 bills, we know it is = 20g
The number of dollars in a quarter of a dollar = 1/4 k
So we write:
421.56 + 20g + 1/4k

Bella used 2/9 of a paper pack, or 72 pieces. How many pieces of paper were there to start with?
Hello!
First, we need to find the unit rate.
72 divided by 2 = 36.
36 x 9 = 324.
There were 324 pieces of paper to start with.
Hope this helps, ~Pooch ♥
Bella used 2/9 of a paper pack, equaling 72 pieces. To find the total number, we solve the proportion (2/9) * x = 72 to deduce that the pack initially contained 324 pieces.
Bella used 2/9 of a paper pack, which amounts to 72 pieces of paper. To find out how many pieces of paper were in the pack to begin with, we need to calculate the total amount of paper in the pack.
Let's set up a proportion where the total number of sheets is x. Since 2/9 of the total is 72, we can write the equation as follows:
(2/9) × x = 72Multiply both sides by 9/2 to solve for x.x = 72 × (9/2)x = 36 × 9x = 324So, the paper pack originally contained 324 pieces of paper.
Identify an equation in standard form for a hyperbola with center (0, 0), vertex (0, 17), and focus (0, 19).
An equation in standard form for a hyperbola with center (0, 0), vertex (0, 17), and focus (0, 19) is; y²/172 – x²/(6√2)² = 1
How to find the equation of a hyperbola?We are given that the hyperbola has;
Center (0, 0), Vertex (0, 17) and Focus (0, 19)
The general form of equation of the given hyperbola has a form of;
y²/a² - x²/b² = 1
Where;
±a is the y- coordinates of the vertices of the parabola (or y-intercepts).
b determines the asymptotes of the hyperbola in the equation y = ± (a/b)x.
From the vertex coordinates of (0.17), we have that; a = ± 17.
From the focus coordinates (0, 19), the y-coordinate of it is; c = 19 .
b can be found from Pythagorean theorem;
c² = a² + b²
Thus;
192 = 172 + b²
b² = 192 – 172
b² = 361 – 289
b = √72 = 6√2
The equation of the hyperbola is;
y²/172 – x²/(6√2)² = 1

The equation in standard form for a hyperbola with the given center, vertex, and focus is y² / 289 - x² / a² = 1.
Explanation:The equation of a hyperbola in standard form is given by:
(x - h)² / a² - (y - k)² / b² = 1 or
(y - k)² / b² - (x - h)² / a² = 1
Given that the center is (0,0) and the vertex is (0,17), we can see that the hyperbola is vertically oriented. Therefore, we can use the form (y - k)² / b² - x² / a² = 1.
Since the center is (0,0), the value of (h, k) is (0,0).
The distance between the center and the vertex is 17 units, which corresponds to the value of b.
The distance between the center and the focus is 19 units, which corresponds to the value of c.
Substituting these values into the equation gives: (y - 0)² / 17² - x² / a² = 1
The equation in standard form for the hyperbola is therefore y² / 289 - x² / a² = 1

what is the answer to a - 5 = -2
The solution to the equation a - 5 = -2 is a = 3. You solve it by adding 5 to both sides, which isolates the variable 'a'.
To solve the equation a - 5 = -2, you need to isolate the variable 'a' on one side of the equation. You can do this by adding 5 to both sides of the equation. Here's the step-by-step process:
Start with the original equation: a - 5 = -2.
Add 5 to both sides: a - 5 + 5 = -2 + 5.
Simplify each side: a = 3.
The answer to the equation is a = 3.
To solve the equation a - 5 = -2, add 5 to both sides which gives us a = 3 as the solution.
The question is asking us to solve the equation a - 5 = -2 for the variable a. To isolate a on one side of the equation, we need to undo the subtraction of 5. We can do this by adding 5 to both sides of the equation:
a - 5 + 5 = -2 + 5
Which simplifies to:
a = 3
Thus, the value of a that solves the equation is 3.

Name the quadrilaterals that have four equal angles. A. rhombus, square B. Square, rectangle C. parallelogram, rhombus D. rhombus, trapezoid
Answer:
B. Square, Rectangle.
Step-by-step explanation:
The correct answer is B. Square, Rectangle.
A square will always have four equal angles and sides.
A rectangle will not have equal sides, but will always have angles of 90 degrees, as does the square.
Hope this helps!
Final answer:
Quadrilaterals with four equal angles are rectangles and squares since they both have four right angles. The correct answer is B: Square, Rectangle.
Explanation:
The question asks us to name the quadrilaterals that have four equal angles. A quadrilateral is a polygon with four sides and four angles. When all the angles in a quadrilateral are equal, they have to be right angles (each measuring 90°) since the sum of all angles in any quadrilateral is 360°. Thus, the types of quadrilaterals with four right angles are:
Rectangle: All four angles are right angles, and opposite sides are equal.
Square: It has all the properties of a rectangle but with the added feature that all four sides are also equal.
Therefore, the rectangles and squares are the quadrilaterals that have four equal angles.
A rhombus has four equal sides, but the angles are not necessarily right angles. A parallelogram has opposite angles that are equal, which does not guarantee that all four angles are equal unless it's a rectangle. Trapezoids generally do not have four equal angles. Therefore, the correct answer to the question is option B: Square, Rectangle.
There are 5 players in a baseball lineup. How many different batting orders are possible for these 5 players? (use FACTORIALS to find the probability of the number of permutations)
Answer:
i believe it is "5!"
Step-by-step explanation:
1x2x3x4x5=120
but the answer is "5!" ( include the exclamation point)
hope this helps (again)
Answer:
5! or 120.
Step-by-step explanation:
Think about this logically:
You have 5 players to start off with, so you have 5 players that can go in the first position.
That leaves you with 4 players. Any one of those 4 players can go in the second position.
And then there were 3 players. Any one of those 3 players can go in the third position.
2 to go! Pick your favorite player out of the 2 available to go in the fourth position.
And that leaves just one player who has to go last.
This can be modeled as: 5x4x3x2x1, or 5!, which equals 120 unique permutations.
An egg is dropped from a height of 90 ft. If acceleration die to gravity is -16ft/s^2 and initial velocity is 0ft/s, approximately how long will it take for the egg to reach the ground?
t = time
Multiply the acceleration by time and add to the height:
The equation becomes H(t) = -16 * t^2 + 90
set h(t) to 0
0 = -16*t^ +90
Subtract 90 from both sides:
-90 = -16*t^2
divide both sides by -16:
t^2 = -90 / -16
t^2 = 5.625
t = √5.625
t = 2.37 seconds, round to 2.4 seconds.
