The distance traveled can be calculated using the formula D = s · t where s is the speed and t is the total time. Which of the situations below represent a total distance of 400 km? Select all that apply.
A) 65 km/hr for 5 hours
B) 100 km/hr for 4 hours
C) 50 km/hr for 8 hours
D) 80 km/hr for 5 hours
Answer:
B. 100km/h x4hours =400km
distance is bigger than time and speed..so you have to multiply .

Solve using the quadratic formula. (Identify a, b, and c. Write the
formula. Show the substitution step.
8n^2 + 4n -2 = 0
Answer:
Step-by-step explanation:
Here a = 8, b = 4 and c = -2. The discriminant here is b^2 - 4ac, which, when the above coefficients are substituted, results in:
discriminant = (4)^2 - 4(8)(-2), or 16 + 64, or 80.
The solutions are:
-(4) ± √80 -4 ± 4√5 4(-1 ±√5) -1 ± √5

The areas of the squares adjacent to two sides of a right triangle are shown below.
What is the area of the square adjacent to the third side of the triangle?
units^2
2
Answer:
Step-by-step explanation:
Without a picture this is murky but if the squares are adjacent to the legs and the unknown square is adjacent to the hypotenuse this is an example of the Pythagorean Theorem. The area of the third square is equal to the sum of the areas adjacent to the sides.
c^2=a^2+b^2
Answer:
11 units^2 or just 22

maths help please!!!!!!
Answer:
VW = √2
Step-by-step explanation:
y = x+1
x²+y²+2x+2y+1=0 (x²+2x+1) + (y²+2y+1) = 1
(x+1)² + (y+1)² = 1 : Circle: (x-h)² + (y-k)² = r² Center (O): (h , k) = (-1 , -1) r = 1
solve for roots: x²+(x+1)²+2x+2(x+1)+1=0
2x² + 6x + 4 = 0 x²+3x+2=0
(x+1)(x+2)=0
x = -1 or x = -2
y = 0 or y = -1
V and W: (-1 , 0) and (-2 , -1) forms a 90° center angle
√vw = √1²+1² = √2

what is the LCM for 9, 18 and 72
Answer:
72
Step-by-step explanation:
9 = 3^2
18 = 2 * 3^2
72 = 2^3 * 3^2
For LCM use common and not common factors with greater exponent.
Use 2^3 and 3^2.
LCM = 2^3 * 3^2 = 8 * 9 = 72
Answer: 72

The measure of ⏜ is 82°, and the measure of ⏜ is 134°.
What is the measure of ∠?
Answer: [tex]\angle BAE=82^{\circ}[/tex]
Step-by-step explanation:
Given
Arc BE measures [tex]82^{\circ}[/tex]
Arc CD measures [tex]134^{\circ}[/tex]
It means Arc BE subtends an angle of [tex]82^{\circ}[/tex] at A i.e.
[tex]\angle BAE=82^{\circ}[/tex]
Given the two functions, which statement is true?
(function is in picture)
A) g(x) is stretched vertically by a factor of 2 and shifted to the right 4 units compared to f(x).
B) g(x) is shrunk vertically by a factor of ½ and shifted to the right 4 units compared to f(x).
C) g(x) is stretched vertically by a factor of 2 and shifted to the left 4 units compared to f(x).
D) g(x) is shrunk vertically by a factor of ½ and shifted to the left 4 units compared to f(x).
Answer:
Option D
Step-by-step explanation:
f(x) = [tex]\text{log}_{15}x[/tex]
Transformed form of the function 'f' is 'g'.
g(x) = [tex]\frac{1}{2}\text{log}_{15}(x+4)[/tex]
Property of vertical stretch or compression of a function,
k(x) = x
Transformed function → m(x) = kx
Here, k = scale factor
1). If k > 1, function is vertically stretched.
2). If 0 < k < 1, function is vertically compressed.
From the given functions, k = [tex]\frac{1}{2}[/tex]
Since, k is between 0 and [tex]\frac{1}{2}[/tex], function f(x) is vertically compressed by a scale factor [tex]\frac{1}{2}[/tex].
g(x) = f(x + 4) represents a shift of function 'f' by 4 units left.
g(x) = f(x - 4) represents a shift of function 'f' by 4 units right.
g(x) = [tex]\frac{1}{2}\text{log}_{15}(x+4)[/tex]
Therefore, function f(x) has been shifted by 4 units left to form image function g(x).
Option D is the answer.
1. What is the value of the y-coordinate of the solution to the system of equations x + 2y = 9 and x - y = 3? 1) 6 3) 3 2) 2 4) 5
Answer:
2) 2
Step-by-step explanation:
Subtract each equation from each other
x + 2y = 9
-x+ y = -3
3y = 6
3 3
So y = 2

Step-by-step explanation:
Henry went to an amusement park with $100.00 and spent all of it. He spent of the money on parking. He spent $42.50 on admission to the park. He spent 20% of the money on food. He paid a $12.75 fee for admission into a water park located inside the amusement park. He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Answer:
19 games
Step-by-step explanation:
Henry went to an amusement park with $100.00 and spent all of it.
Starting amount = $100.00
He spent $42.50 on admission to the park.
Amount left = $100.00 - $42.50
Amount left = $57.5
He spent 20% of the money on food.
Amount spent = 20% of amount left ($57.5) = $11.5
Amount left = $57.5 - $11.5 = $46
He paid a $12.75 fee for admission into a water park located inside the amusement park.
Amount left = $46 - $12.75
Amount left = $33.25
He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Number of games = Amount left / Cost per game
Number of games = $33.25 / $1.75 = 19
Lucy goes to a restaurant and the subtotal on the bill was x dollars. A tax of 4% is applied to the bill. Lucy decides to leave a tip of 22% on the entire bill (including the tax). Write an expression in terms of xx that represents the total amount that Lucy paid.
Answer: 1.2688x
Step-by-step explanation:
Bill plus tax is equal to
[tex](1+.04)(x)\\ =1.04x[/tex]
tip added on
[tex](1.04x) ( 1.22) = 1.2688x[/tex]
why do banks charge for transaction fees?
Answer:
To make a profit and pay operating expenses, banks typically charge for the services they provide. When a bank lends you money, it charges interest on the loan. Even fee-free checking and savings accounts have some fees.

have a nice day ;)
Answer:
A possible answer could be:
Charging small fees for a specific service is another way to pay for that service and to help the bank make money. Fees are also used to discourage bad behavior, like making overdrafts.
