Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
Answer:
x=7 y=77
Step-by-step explanation:
Subtract 4x from 9x you get 5x
subtract 14 from 49 you get 35
5x=35
9*7=63+14=77
4*7=28+49=77
How many 12 Feet 2 x 4 would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Your question has confusing details. So, I will rephrase as:
How many 2' x 4' would be needed for Bottom Plates and Double Top Plates on a Building 25' x 50' ?
Answer:
12.5 plates
Step-by-step explanation:
Given
Building dimension:
[tex]Length = 25ft[/tex]
[tex]Width = 50ft[/tex]
Plates
[tex]Length = 2ft[/tex]
[tex]Width= 4ft[/tex]
To do this, we have to divide the dimension of the building by the dimension of the plates
So, we have:
[tex]n = \frac{Length\ of\ Building}{Length\ of\ Plates}[/tex]
and
[tex]n = \frac{Width\ of\ Building}{Width\ of\ Plates}[/tex]
For the length, we have:
[tex]n = \frac{25}{2}[/tex]
[tex]n = 12.5[/tex]
For the width, we have:
[tex]n = \frac{50}{4}[/tex]
[tex]n = 12.5[/tex]
So, 12.5 of the plates are needed

Evaluate the expression. 3.14(7)² =
Answer:153.86
Step-by-step explanation:
Find the value of x. Write your answer in simplest form.
Answer:
x = (9/2)√2
Step-by-step explanation:
The ratio of leg x to the hypotenuse 9 is equal to the cosine of 45 degrees:
cos 45 degrees = x/9
To find the value of x, multiply both sides of this equation by 9, obtaining 9*cos 45 degrees, which comes out to x =9(1/√2). Rationalizing the denominator, we get x = (9/2)√2
Every year, a car loses 15% of the value it had the year before. If the car's initial value is $ 24,000, then how long will it take for the car to be worth half of its value?
Answer:
4.62 years
Step-by-step explanation:
Half the car's value =>$24,000/2 = $12,000
The formula for exponential decrease =
y = a(1 - r)^t
y = Initial value = $24,000
a = Value after time t = $12,000
r = Decrease rate = 15% = 0.15
t = time in years =??
Hence,
24,000 = 12000 ( 1 - 0.15)^t
Divide both sides by 12000
24000/12000 = 12000 ( 0.85)^t/ 12000
2 = 0.85^t
We take the logarithm of both sides
log 2 = log (0.85)^t
log 2 = t log 0.85
Divide both sides by log 0.85
t = log 2/log 0.85
t = 4.62098120373 years
Approximately = 4.62 years
It would take 4.62 years to be worth half the initial price

If a driver takes 6 hours to get to the town market which is 336 km away from his house, what is his average speed?
Answer:
[tex]56\ \text{km/h}[/tex]
Step-by-step explanation:
[tex]t[/tex] = Time taken = [tex]6\ \text{hours}[/tex]
[tex]d[/tex] = Distance = [tex]336\ \text{km}[/tex]
Average speed is given by
[tex]s=\dfrac{\text{Distance}}{\text{Time}}=\dfrac{d}{t}[/tex]
[tex]\Rightarrow s=\dfrac{336}{6}[/tex]
[tex]\Rightarrow s=56\ \text{km/h}[/tex]
The average speed of the driver is [tex]56\ \text{km/h}[/tex].
