Which equation represents a line which is perpendicular to the line y= -5/4x - 4?
A. 4y - 5x = -4
B. 4x - 5y = 15
C. 5x + 4y = -8
D. 4x + 5y = 40
Answer:
b
Step-by-step explanation:
4x-5y=15
-5y=-4x+15
y=4/5x+15
4y - 5x = -4 represents the line which is perpendicular to the line y= -5/4x - 4. Option A is correct.
What are perpendicular lines?Two lines are perpendicular to each other if the product of their slopes is equal to -1.
Given,
y= -5/4x - 4
Slope of this line =m1 = -5/4
Let, slope of required line be m2
Then, (m1)(m2) = -1
(-5/4)m2 = -1
m2 = 4/5
The required line has slope = 4/5
Hence, 4y - 5x = -4 has slope equal to 4/5.

Answer:
[tex]Total = 2.35n[/tex]
Step-by-step explanation:
Given
Monday = n
Tuesday = 90% of Monday
Wednesday = 50% of Tuesday
Required
Determine the total miles
We have:
Tuesday = 90% of Monday
Substitute n for Monday
Tuesday = 90% of n
[tex]Tuesday = 90\% * n[/tex]
Express percentage to decimal
[tex]Tuesday = 0.90 * n[/tex]
[tex]Tuesday = 0.90n[/tex]
We also have that:
Wednesday = 50% of Tuesday
Wednesday = 50% * Tuesday
Substitute 0.90n for Tuesday
[tex]Wednesday = 50\% * 0.90n[/tex]
Express percentage to decimal
[tex]Wednesday = 0.50 * 0.90n[/tex]
[tex]Wednesday = 0.45n[/tex]
The total number of miles is:
[tex]Total = Monday + Tuesday + Wednesday[/tex]
[tex]Total = n + 0.90n + 0.45n[/tex]
[tex]Total = 2.35n[/tex]

£2,300 is invested for 4 years at 5% per year simple interest work out the total interest
Answer:
£460
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2300 × 0.05 × 4 = 460
I = £ 460.00
The simple interest accumulated
on a principal of £ 2,300.00
at a rate of 5% per year
for 4 years is £ 460.00.

the mean weight of 100 students in a certain class is 71kg the mean weight of boys is 65kg and that of girls is 75kg what is the number of boys and girls
Answer:
There are 60 girls and 40 boys in the class.
Step-by-step explanation:
Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:
1 x 75 + 0 x 65 + 75
0.9 x 75 + 0.1 x 65 = 74
0.8 x 75 + 0.2 x 65 = 73
0.7 x 75 + 0.3 x 65 = 72
0.6 x 75 + 0.4 x 65 = 71
Thus, there are 60 girls and 40 boys in the class.

20 pounds of beans are distributed equally into 16 bags to give out at the food bank how many pounds of beans are in each bag
Daniel bought a total of 8 pounds if peanuts and cashews. Peanuts, p, cost $2 per pound and cashews, c, cost $5 per pound. The total amount Dani spent on the peanuts and cashews was $25. Which system of equations could be solved to find how many pounds kf peanuts dani bought
A.{2p+5c=25
p+c=9
B.{5p+2c=25
p+c=8
C.{2p+5c=8
p+c=25
D.{2p=8
5c=25
Answer:
I believe the answer is C.
Step-by-step explanation:
given we have peanuts to be $2 per pound, and cashews $5 per pound. If we use the equation p+c=25 then p would be (2×10=20), and c would be (5×1=5). then, to solve the problem we would do p+c=25 which p would be 20, and c would be 5, then add and it would equal 25.
