Which of the four images was formed by a reflection of the letter T?
A
B
C
D
Answers
The answer is not A because T would be flipped, the answer is not D because T can not be reflected in that area without translations, and the answer is not B because T cannot (once again) be reflected in such locations without translations, Therefore, that leaves us with our best bet being the answer C.

You sell 3 hamburgers at $2.10 each plus 0.38 tax. A customer gives you a $10.00 bill. How much change does he get?
Answers
Given is the Rate of each hamburger = 2.10 dollars each.
The number of hamburgers that we sell = 3 hamburgers.
Charges for all 3 hamburgers = 3 x 2.10 = 6.30 dollars.
Tax charged on these 3 hamburgers = 0.38 dollars.
Total Bill = Charges for 3 hamburgers + Tax
Total Bill = 6.30 + 0.38 = 6.68 dollars.
Customer paid = 10 dollars.
The amount to be returned to customer = Bill paid by customer - Total Bill charged = 10 - 6.68 = 3.32 dollars.
Hence, the customer would get a change of 3.32 dollars.

a bird is in a tree 30 feet off the ground and drops at Twigs at lands on a rose bush 25 ft below. the function h(t)=-16t^2+30, where T represents the time in seconds gifts the height H and feet of The Twig above the ground as it falls when will The Twig land on the bush
Answers
First, we will start with what we are given the equation: h(t) = -16t^2 + 30
Now, we should input a 5 for the h(t) because we want the seconds that will give us a height of 5 seconds.
5 = -16t^2 + 30
Solve the equation:
0 = -16t^2 + 25
To solve this, you could use the quadratic formula or factor out a -1 and you will have the difference of two squares.
Either way the answer is 1.25 seconds.
Answer:
After 1.25 seconds the twig land on the bush.
Step-by-step explanation:
Given function that shows the height of twig from the ground after t seconds,
[tex]h(t)=-16t^2+30[/tex]
When twig is on the bush,
h(t) = 5 feet ( ∵ the distance from bush to ground = 30 - 25 = 5 feet )
[tex]\implies -16t^2+30=5[/tex]
[tex]-16t^2=-25[/tex]
[tex]t^2=\frac{25}{16}[/tex]
[tex]\implies t=\pm \frac{5}{4}[/tex]
Since, time can not be negative,
Hence, t = [tex]\frac{5}{4}[/tex] ≈ 1.25
Therefore, after 1.25 seconds the twig land on the bush.

if an arc has a measure of 97° and the circle has radius = 10, what is the arc length
Answers
97/360 x 62.8 = 16.92
arc length = 16.92 ( round answer as needed)
Final answer:
The arc length of a circle with a radius of 10 units and a central angle of 97° is calculated using the formula for arc length, yielding an arc length of approximately 16.975 units.
Explanation:
The question asks us to find the arc length of a circle with a certain radius when a central angle is given. To find the arc length, we use the formula:
Arc length (s) = (θ/360) × 2πr
Where θ is the central angle in degrees, r is the radius of the circle, and π is approximately 3.14159. Since we know the central angle is 97° and the radius is 10, we can plug these values into the formula:
s = (97/360) × 2×π×10
s ≈ (97/360) × 2× 3.14159 × 10
s ≈ 16.975
Therefore, the arc length is approximately 16.975 units.

Milo's pancake recipe makes 9 servings. It calls for 3/4 cup milk. Milo wants to make 6 servings. How much milk will he need?
Answers
It says that the recipe for 9 servings would require 3/4 cup milk.
He wants to prepare recipe for 6 servings. Let's assume it requires X cups milk.
Now we can use concept of proportions to solve this problem.
The proportion of X cups for 6 servings would be same as 3/4 cup milk for 9 servings. Mathematically, we can write it as follows :-
[tex] \frac{X \;cups \;milk}{6 \;servings} = \frac{\frac{3}{4} \;cups \;milk}{9 \;servings} \\\\
Or\; \frac{X \;cups \;milk}{\frac{3}{4} \;cups \;milk} = \frac{6 \;servings}{9 \;servings} \\\\
\frac{X }{\frac{3}{4} } = \frac{6 }{9 } \\\\
X = \frac{6}{9}*\frac{3}{4} \\\\
X = \frac{6*3}{9*4} \\\\
X = \frac{18}{36} \\\\
X = \frac{1}{2} \;cup \;milk [/tex]
Hence, we require [tex] \frac{1}{2} [/tex] cup milk for 6 servings.
a dinosaur fossil is 92,170,000 years old. How can you express this age in scientific notation with the highest level of precision?
Answers
Answer: Its age is expressed as [tex]9.217\times 10^7[/tex]
Step-by-step explanation:
Since we have given that
Age of dinosaur fossil = 92170000 years old
We need to write in scientific notation with the highest level of precision.
Since we know that Scientific notation means put the decimal just after unit digit and for all remaining digit there is to the power of 10.
So, it becomes,
[tex]92170000=9.217\times 10^7[/tex]
Hence, its age is expressed as [tex]9.217\times 10^7[/tex]
A hockey game between two teams is 'relatively close' if the number of goals scored by the two teams never differ by more than two. In how many ways can the first 12 goals of a game be scored if the game is 'relatively close'?
Answers
This question falls under the combinatorial mathematics branch. Due to the complex nature of the problem which involves permutations and combinations, it's necessary to use a systematic approach or a computer algorithm to find the total number of scoring sequences that keeps the game 'relatively close'. Hence, the actual numerical answer would require a stronger background in combinatorics.
Explanation:This question belongs to the subject of combinatorial mathematics, particularly involving permutations and combinations. In this scenario, 'relatively close' is defined as the number of goals scored by the two teams never differing by more than two. The total number of goals scored in the game is twelve.
Let's denote the two teams as Team A and Team B. The game can start in three ways: either Team A scores twice, Team B scores twice, or each team scores once. After that, at any point, the next goal can either maintain the score within the 'relatively close' range of two goals or equalize the score.
Determining the total number of scoring sequences under these conditions requires generating a tree diagram and counting all the possible paths, subject to the condition that the absolute difference between the number of goals for the two teams does not exceed two at any stage. Due to the combinatorial complexity, this task could be difficult without using a systematic approach or computer algorithm.
Therefore, to actually answer this question, one would require a stronger background in combinatorics, and most likely the assistance of programming or mathematics software to execute a brute force count or implement a more advanced mathematical solution.
