Answer:
y = 18 - 6x
Step-by-step explanation:
Given :
Speed or rate = 6mph
y = distance away from home
x = hours biked
Initial distance from home = 18 miles
General form of Slope - intercept form of an equation :
y = mx + c
Where ;
m = gradient or slope = rate of change
c = intercept or initial value or amount, always constant
x = independent variable
y = dependent variable
Hence,
For the question above :
Distance away from home, depends on the number of hours biked
y = 18 - 6x

F
is directly proportional to
a
.
If
F
=
36
when
a
=
9
find,
F
when
a
=
4
Step-by-step explanation:
F = ka, where k is a real constant.
When a = 9, F = 36.
=> (36) = k(9), k = 4.
Therefore when a = 4,
F = (4)(4) = 16.
The value of F is 16 when a is 4.

HELP‼️‼️
Answer:
what are the valus of a and b
Step-by-step explanation:
Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then find the value of y when x=16...
y=7 when x=2
Step-by-step explanation:
y = kx, where k is a real constant.
When x = 2, y = 7.
=> (7) = k(2), 2k = 7, k = 3.5.
Therefore when x = 16,
y = (3.5)(16) = 56.
The value of y is 56 when x is 16.
The formula for direct variation is y = kx
Using the known x and y solve for k:
7 = k2
Divide both sides by 2:
k =7/2 = 3.5
Now solve for y when x = 16:
y = 3.5(16)
y = 56
Identify the solution and graph of the given inequality.

Answer:
21
Step-by-step explanation:
9×3=27
3×2=6
27-6=21
An elementary school bus comes at 8:15 am every morning to pick up children in a neighborhood. The probability that the bus will be late is 0.19 and the probability that the bus will be early is 0.02.
What is the probability that the bus will arrive early next two days?
What is the probability that the bus will arrive on time next two days?
In two or more complete sentences, explain your calculations for parts A and B. In your explanation, include their similarities and differences.
Answer:
a. .02 * .02 = .0004
b. (1 - .02 - .19) = .79; .79*.79 = .6241
Step-by-step explanation:
The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.
What is Probability?Probability is the likeliness of an event to happen, it has a range from 0 to 1.
Probability that the bus will be late is 0.19
Probability that the bus will be early is 0.02.
The probability that the bus will arrive early next two days is
= 0.02 * 0.02
=0.0004
The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.
The probability that the bus will arrive on time next two days
= (1 - 0.02 -0.19) = 0.79
The probability that the bus will come on time is more as the probability of coming early or late is less.

A) V28
B) 500
C) 7162
Answer:
[tex]\sqrt{28} = 2\sqrt{7}[/tex]
[tex]\sqrt {500} = 10 \sqrt {5[/tex]
[tex]\sqrt {162} = 9 \sqrt {2[/tex]
Step-by-step explanation:

Express in simplified form
[tex]\sqrt {28[/tex]
Express 28 as 4 * 7
[tex]\sqrt{28} = \sqrt{4} * \sqrt{7}[/tex]
Take positive square root of 4
[tex]\sqrt{28} = 2 * \sqrt{7}[/tex]
[tex]\sqrt{28} = 2\sqrt{7}[/tex]
[tex]\sqrt {500[/tex]
Express 500 as 100 * 5
[tex]\sqrt {500} = \sqrt {100} * \sqrt {5[/tex]
Take positive square root of 100
[tex]\sqrt {500} = 10 * \sqrt {5[/tex]
[tex]\sqrt {500} = 10 \sqrt {5[/tex]

Leroy borrowed P1500 at an annual simple interest rate of 12%. He paid P270 in interest. For what time period did Leroy borrow the money? A. 8 years B. 5 years C. 18 months D. 18 years
Answer:
C. 18 months
Step-by-step explanation:
Given data
Principal= P1500
rate= 12%
Simple interest= P270
We know that
Simple interest= PRT/100
substitute
270= 1500*12*T/100
cross multiply we have
270*100= 1500*12*T
27000= 18000 T
divide both sides by 18000
T= 27000/18000
T=1.5 years
That is 12 months + 6 months
in all = 18 months
The time is C. 18 months
2) Gold has a density of
19.3g/cmº. The gold ring has a
mass of 15g. Work out the
volume of the gold in the ring?
Answer:
V = 150/193 cm³
Step-by-step explanation:
Density = Mass/Volume
Substitute the given values into the equation.
19.3 = 15/V (Given)
19.3V = 15 (Multiplied V on both sides)
V = 150/193 (Divided 19.3 on both sides)
