A car drives 215 km east and then 45 km north. What is the magnitude of the car's displacement? Round your answer to the nearest whole number. km
Answer:
220 km
Step-by-step explanation:
Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle. The hypotenuse is his displacement for the combination of the two segments.
D = √(215² + 45²)
= √(46,225 + 2,025)
= √48,250 = 219.6588... km
Nearest whole number: 220 km
Answer:
220

You have 12 cards numbered as follows: 2,5,8,10,12,15,18,20,10,7,9,11. What is the probability of choosing an even number, given that it is a multiple of 5?
a. 5/12
b. 7/12
c. 1/2
d. 3/5
Answer:
7/12
Step-by-step explanation:
Simple:
There are 12 numbers in all and only 7 even numbers
Since there are 7 even numbers the probability of rolling an even number is 7/12.
This means that there are 7 outcomes of an even number
Therefore the probability of choosing an even number
=7/12

Caroline puts $400 into a savings account that earns 6% annually. Write a function that represents this situation, where t is the time in years. Solve algebraically after how many years she will get $1200 in her account (round it to the nearest year).
Answer:
19
Step-by-step explanation:
this is exponential function formula=[tex]f(x)=a(b)^x[/tex]
so this would be the answer
a=400
b=1.06(because it is increasing)
x=is unknown
[tex]400(1.06)^x[/tex] so that is the formula i used

The square of the sum of x and 5 is equal to y
Answer:
[tex]\sqrt{x+5}[/tex] = y
Step-by-step explanation:
║You can rewrite the equation in different ways.
[tex]\sqrt{x+5}[/tex] = yy = [tex]\sqrt{x+5}[/tex]x = y² − 5[Because there's no given value for x or y, we can only rewrite it]
What is the equation of the following line? Be sure to scroll down first to see
all answer options.
A. y = 1/5x
B. y = -5x
C. y = 3x
D. y = 15x
E. y = -1/5x
F. y = 5x
Answer:
only A is correct
Step-by-step explanation:
To get the equation of the given line, we just have to see if the point given fits into any of the equation
The given point is (15,3)
a) y = 1/5x = 1/5 * 15 = 3
This is correct
b) y = -5(-75) = -375; this is not correct
c) y = 3x
y = 3(15) = 45
This is not correct
d) y = 15x
y = 15(15) = 225
This is incorrect
e) y = -1/5x
y = -1/5 * 15 = -3
This is incorrect
f) y = 5x
y = 5(15) = 75
This is also incorrect
Simplify: 40 - 24÷ {7 + (7-15)}
please I need this answer ASAP
Answer: 64
Step-by-step explanation:
40 - 24 ÷ [7 + (7-15)]
= 40 - 24 ÷ (7 - 8)
= 40 - 24 ÷ (-1)
= 40 + 24
= 64
On solving the given expression 40 - 24 ÷ {7 + (7 - 15)}, we get 64.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the function -
40 - 24÷ {7 + (7-15)}
We have -
40 - 24 ÷ {7 + (7 - 15)}
Using the Rule of BODMAS, we can solve the function as -
40 - 24 ÷ {7 + (7 - 15)}
40 - 24 ÷ {7 + (7 - 15)}
40 - 24 ÷ {7 - 8}
40 - 24 ÷ (- 1)
40 - (- 24)
64
Therefore, on solving the given expression 40 - 24 ÷ {7 + (7 - 15)}, we get 64.

Find the measure of each angle. ∠EFG and ∠LMN are supplementary angles, m∠EFG=(3x+17)º, and m∠LMN=(12x−5)º.
Answer:
∠EFG=(3× 11.2+17)º = 50.6°
∠LMN= (12×11.2−5)º = 129.4°
Step-by-step explanation:
We know that if two angles are supplementary two each other sum of these two angles is equal to 180°.
It is given that ∠EFG and ∠LMN are supplementary angles.
Therefore, ∠EFG +∠LMN = 180°
Given that: ∠EFG=(3x+17)º and ∠LMN=(12x−5)º
⇒ (3x+17)º + (12x−5)º =180°
⇒ (15x+12)° = 180°
⇒15x = 168°
⇒ x = 168°/15
x = 11.2°
Then, ∠EFG=(3× 11.2+17)º = 50.6°
Also, ∠LMN= (12×11.2−5)º = 129.4°

Hazel has already written 2 pages, and she expects to write 2 pages for every additional
hour spent writing. After spending 24 hours writing this week, how many pages will Hazel
have written in total?
Answer:
50 pages
Step-by-step explanation:
We can set up an equation for this in slope-intercept form.
The slope is 2 due to her expecting to write 2 pages an hour.
The y-intercept is 2 because she has already written 2 pages.
The full equation is y = 2x + 2.
We can plug 24 in for x to get y = 48 + 2, which simplifies to y = 50.
