65 min by riding her bike
x min by boarding a bus
since the time taken to get to the dentist with a bus is 5min shorter than twice the time taken with a bike, it can be written as
(2x) - 5 = 65
2x = 65 + 5
2x = 70
x = 35 min. (A)
The vertex of this parabola is at (3, 5) . When the y-value is 6, the x-value is - 1 What is the coefficient of the squared term in the parabola's equation? (3, 5) A. -4 B. 4 C. 2 D.2
Answer:
The correct approach is Option A (-4).
Step-by-step explanation:
The given values are:
Vertex of the parabola,
(h, k) = (3, 5)
Passing through,
(x, y) = (-1, 6)
As we know,
The equation of parabola is:
⇒ [tex]x=a(y-k)^2+h[/tex]
On substituting the given values in the above equation, we get
⇒ [tex]-1=a(6-5)^2+3[/tex]
⇒ [tex]-1=a+3[/tex]
On substracting "3" from both sides, we get
⇒ [tex]-1-3=a+3-3[/tex]
⇒ [tex]a=-4[/tex] (coefficient of squared term)
Thus the above is the right choice.
Find the slope of the line above.

A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism
Answer: volume = 5.5625 cubic units.
Step-by-step explanation:
A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.
We know that for a cube with side length L, the volume is:
V = L^3
And we know that these small cubes have an edge length of 1/4 units.
Then the volume of each small cube is:
V = (1/4)^3 cubic units
V = (1/64) cubic units
And the volume of the prism will be 356 times that, then the volume of the prism is:
volume = 356*(1/64) cubic units
volume = 5.5625 cubic units.

Ben rolled a number cube numbered one through six. It landed on an odd number 30 times. What is the probability that it lands on an odd number on the next roll?
Answer:
1 /2
Step-by-step explanation:
Sample space of number cube : (1, 2, 3, 4, 5, 6)
Odd numbers on cube : (1, 3, 5) = 3 odd numbers
Since each roll of number cube is independent, the number of times it has landed between fire does not matter :
Therefore, probability of landing on a odd number is :
P = required outcome / Total possible outcomes
P = 3 / 6
P = 1/2

Mia bought 2 adult tickets and 4 kid's tickets. Each adult ticket cost $13.50 and each kid ticket cost $10.25. How much did Mia spend on tickets
Answer:
Mia spent 68 dollars.
Step-by-step explanation:
The equation would be 2(13.50) + 4(10.25) = x
Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.
During a basketball game, one of the players scores 8 points for her team. If the points she scored represent 20% of the team's total points, as shown below, how many points did the team score during the game?
Answer:
40points
Step-by-step explanation:
Given data
Let the total points the team scored be x
so that
20% of x= 8 points
let us solve for x
20/100*x= 8
0.2*x= 8
0.2x= 8
Divide both sides by 0.2
x= 8/0.2
x= 40 points
Hence the time scored 40points
If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?
Answer:
w = width
h = height
2(w+h) < 200
w + h < 100
since w = 36, then
36 + h < 100
h < 100 - 36
h < 64
Step-by-step explanation:
The perimeter of the rectangular picture frame can be calculated by the equation,
2h + 2w = P
where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,
2h + 2(36 in) < 200
The inequality gives h as,
h < 64
Thus, the answer is letter A.
if i got shorts for 30 dollars and the original price was 40 what was the discount
Answer:
25%
Step-by-step explanation:
30/40 = 0.75 = 75% paid
100-75 = 25% discount
Answer:
[tex]25\%[/tex]
Step-by-step explanation:
To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;
[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]
Substitute in the given values;
[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]
Solve;
[tex]\frac{10}{40}=\frac{percent}{100}[/tex]
Simplify,
[tex]\frac{1}{4}=\frac{percent}{100}[/tex]
Cross products,
[tex]100 = 4(percent)[/tex]
Inverse operations,
[tex]100=4(percent)\\/4\\\\25 = percent[/tex]
The middle person in a row is the 18th, how many persons are in the row?
Answer:
35
Step-by-step explanation:
You have 17 either side to make 18 the middle e.g if 2 was the middle then you have 1 either side.
Answer:
36
Step-by-step explanation:
if 18 is the middle there are 17 on each side of that person so 17+17+1=36

At figure skating practice, Michelle landed 15 out of 18 attempts at a double axel. What is the experimental probability that she will successfully land a double axel?
Answer:
5/6 or 0.8333333333 (83%)
Step-by-step explanation:
So she landed 15 out of 18 so we are going to divide 15 by 18 (15/18) which gets us 5/6 or 0.8333333333 or 83%

Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
1005.68 litres
Step-by-step explanation:
Steps to answering this question
Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km1 gallon = 3.78541 litres
13.6 gallons x 3.78541 = 51.48 litres
1 mile = 1.60934 km
321.7 miles x 1.60934 = 517.72 km
Litre needed per kilometer = 517.72 km / 51.48 = 10.06
Litres needed for 100 km = 100km x 10.06 = 1005.68 litres

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.
Answer:
523.6 km
Step-by-step explanation:
Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...
time = distance/speed
Then the total travel time in hours is ...
x/160 +(1020-x)/105 = 8
21x +32640 -32x = 26880 . . . . . multiply by 3360
5760 = 11x . . . . . . . . . add 11x -26880
523.6 ≈ x . . . . . . . . . . divide by 11
Aidan traveled about 523.6 km by train.
