Phil spent $17 of his $157 pocket money on eating out for one meal. What percent of Phil's pocket money did he spend on eating out for one meal?
Answer:
17/157=10.82%
Step-by-step explanation:
Answer: 10.8% (maybe 11% depending on if your teacher wants a decimal in the answer or not)
Step-by-step explanation:
157 x 0.108 = 16.956
16.956 can be rounded up to 17.
Therefore, Phil spent about 10.8% of his pocket money ($157).
A group of students were asked which club they planned to join.
Club Percent of Students
Garden Club 0.1
Robotics Club 0.2
Technology Club 0.5
Zoology Club 0.2
Compare the probabilities of a randomly selected student joining a club and interpret the likelihood. Choose the statement that is true.
The student will be more likely to join the Robotics Club than the Garden Club because P(Robotics) > P(Garden).
The student will be equally likely to join the Robotics Club or Technology Club because P(Robotics) = P(Technology).
The student will be more unlikely to join the Zoology Club than the Robotics Club because P(Zoology) > P(Robotics).
The student will be more likely to join the Garden Club than the Robotics Club because P(Garden) < P(Robotics).

Is the relation a function? Complete the sentence.
Answer:
the inly way this could be a function is iif it is x times 0 plus 2
Answer:
yes
Step-by-step explanation:
You want to know if the relation shown is a function.
FunctionA set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.
__
Additional comment
Yes, it's that simple.
Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.

Answer: 2 small prism could fit.
Step-by-step explanation: The large prism is 4 feet tall, 5 feet long, And 3 feet wide. So it would take to small prism to fit because the small prism is 2 feet tall, 2.5 feet long, And 1.5 feet long. Do you see it the small prism is exactly half the size of the large prism there the large prism could fit two small prism with in its self.

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

Answer:
width: 2 : 15volume: 8 : 3375surface area: 4 : 225Step-by-step explanation:
Given a model has a scale factor of 2:15 with respect to the original car, you want to know the ratios of model : original for width, volume, and surface area.
RatiosThe scale factor is the ratio of linear dimensions, such as width. This means the ratio of widths will be 2:15, the same as the scale factor.
Areas have units of the square of a linear dimension. Hence the ratio of areas is the square of the ratio of linear dimensions, the square of the scale factor. The ratio of surface areas will be 2²:15² = 4:225.
Volumes have units of the cube of a linear dimension. Hence the ratio of volumes is the cube of the ratio of linear dimensions, the cube of the scale factor. The ratio of volumes will be 2³:15³ = 8:3375.
The model : original ratios are ...
