Answer:
a. 125 – 7d
Step-by-step explanation:
Let d be the number of days.
Given the following data;
Total distance (month) = 125 miles
Distance covered per day = 7 miles
To determine how many miles he has left to run after running for "d" days, this mathematical expression can be used;
Total distance - distance covered per day = number of miles remaining

what are the 3 basic steps to writing equations
Answer:
Putting things in the right place
Reading the question
Using the correct symbol
Step-by-step explanation:
Putting things in the right place is very important
Example: 2+2=4
If I accidently did 2+4=2 then the answer would be incorrect.
Reading the question
You could read a question wrong in an exam so you may answer incorrectly, so if you finished the exam then always check your answers
Using the correct symbol is important because you could know the answer but write the wrong symbol and not get the mark

The 89 bus comes every 8 minutes. The 368 bus comes every 12 minutes. Both buses are at the same stop at 9 am. At what time will they be at the same stop.
Answer:
9:24 am
Step-by-step explanation:
89 bus = 8 minutes
368 bus = 12 minutes
Find the lowest common multiple(L.C.M) of 8 minutes and 12 minutes
8 minutes = 16, 24, 32, 40, 48
12 minutes = 24, 36, 48, 60
The L.C.M of 8 minutes and 12 minutes is 24 minutes
Both buses are at the same stop at 9 am.
The next time both buses will be at the same stand = 9 am + 24 minutes
= 9:24 am
Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 12a5 and 9a5.
Given:
The lengths of legs of a right triangle are [tex]12a^5[/tex] and [tex]9a^5[/tex].
To find:
The perimeter of a right triangle.
Solution:
In a right angle triangle,
[tex]Hypotenuse=\sqrt{Leg_1^2+Leg_2^2}[/tex]
[tex]Hypotenuse=\sqrt{(12a^5)^2+(9a^5)^2}[/tex]
[tex]Hypotenuse=\sqrt{144a^{10}+81a^{10}}[/tex]
[tex]Hypotenuse=\sqrt{225a^{10}}[/tex]
On further simplification, we get
[tex]Hypotenuse=\sqrt{(15a^{5})^2}[/tex]
[tex]Hypotenuse=15a^5[/tex]
Now, the perimeter of the triangle is the sum of all of its sides.
[tex]Perimeter=Leg_1+Leg_2+Hypotenuse[/tex]
[tex]Perimeter=12a^5+9a^5+15a^5[/tex]
[tex]Perimeter=36a^5[/tex]
Therefore, the perimeter of the right triangle is [tex]36a^5[/tex].

A helicopter is 665 feet above the ground. A girl is looking up at the helicopter to form a line. Her line of sight is 5 feet off the ground. The distance between the girl and the helicopter is 280 feet.
Answer:
67
Step-by-step explanation:
we are given adjacent and opposite sides. thus tan^-1 would be used to determine the angle
opposite side = 665 - 5 = 660
adjacent side = 280
tan = opposite / adjacent
[tex]tan^{-1}[/tex] (660/280) = 67

Calculate the bank charges if a client wants to send a cash amount of R450 to a friend at an ATM without using a card
Answer:
R6.775
Step-by-step explanation:
Given that :
The transaction fee charged is calculated using the relation :
Transaction fee = R2.50 + 0.95%(amount deposited)
If amount to deposit is R450 ; the bank charge will be:
R2.50 + 0.95%(Amount deposited)
R2.50 + 0.0095(450)
R2.50 + R4.275
R(2.50 + 4.275)
R6.775

Em 2016 o brasil vendeu para o exterior cerca de 3,5 milhoes de ingressos para espectadores estrangeiros sabendo total de ingressos vendidos é de 7,9 milhoes a quantia de ingressos vendida para a população brasileira foi de? a) 4.050.000 B) 4.400.000 C) 5.000.000 D) 5.500.000
Responder:
4.400.000
Explicação passo a passo:
A quantidade total de ingressos vendidos = 7,9 milhões = 7.900.000
Desse total, o valor vendido ao espectador estrangeiro = 3,5 milhões, = 3,5 milhões
O valor dos ingressos vendidos ao espectador brasileiro será a diferença entre o valor total do ingresso vendido e o total vendido ao espectador estrangeiro.
7.900.000 - 3.500.000 = 4.400.000

how do you find the area of a rectangle
Answer:
You multiply length by width.
Step-by-step explanation:
To find the area of a rectangle you multiply length and width together.
For example if a rectangle has length 2 and width 3 the area of the rectangle would be 6, since 2 * 3 is 6.
Answer:area =length x width

To find the area of the base, multiply 15 times 16 then divide by 2
Then multiply by 19 to find the volume of the shape
Step-by-step explanation:
The base is a triangle
The area of a triangle = base length times height divided by 2
The triangle has a base length of 16 and a height of 15
So to find the area of the base we multiply 15 times 16 and divide that by 2
The volume of a prism is equal to the area of the base times the length of the prism
The length of the prism is 19 so we would then multiply by 19

The slope of a line that passes through the points (-6, w) and (-10, 4) ls 1/8. What is the
value of w?
Answer:
[tex]\displaystyle w=\frac{9}{2}=4.5[/tex]
Step-by-step explanation:
We can use slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
So:
[tex]\displaystyle m=\frac{4-w}{-10-(-6)}=\frac{4-w}{-10+6}=\frac{4-w}{-4}[/tex]
We are given that this equals 1/8. Therefore:
[tex]\displaystyle \frac{4-w}{-4}=\frac{1}{8}[/tex]
Solve for w. Cross-multiply:
[tex]-4(1)=8(4-w)[/tex]
Distribute:
[tex]-4=32-8w[/tex]
Isolate:
[tex]-8w=-36[/tex]
So:
[tex]\displaystyle w=\frac{-36}{-8}=\frac{9}{2}=4.5[/tex]
In parallelogram RSTU if RT=36 find RV.

3x+2y=4
2x-3y=7
a) 2, - 1
b)2 , 1
c)1 , 2
d)- 2 , - 1
Answer:
a) 2, -1
Step-by-step explanation:
3x + 2y = 4
2y = 4 - 3x
y = 2 - 3x/2
2x - 3y = 7
2x - 3×(2 - 3x/2) = 7
2x - 6 + 9x/2 = 7
4x/2 + 9x/2 = 13
13x/2 = 13
13x = 26
x = 2
3×2 + 2y = 4
6 + 2y = 4
3 + y = 2
y = -1
