The equation that represent the number of students in High School A at time t is AA = 500 + 80tt.
The equation that represent the number of students in High School B at time t is BB = 700 + 30tt.
The number of students when both schools would have the same number of students is 820.
When would the school have the same number of students?
The equation that represent the number of students in High School A :
current number of students + (number of years x rate of increase)
AA = 500 + 80tt.
The equation that represent the number of students in High School B at time t is:
current number of students + (number of years x rate of increase)
BB = 700 + 30tt.
When the schools would have the same number of students, the two equations would be equal:
700 + 30tt = 500 + 80tt
700 - 500 = 80tt - 30tt
200 = 50tt
tt = 200 / 50
tt = 4
Population = 500 + (80 x 4)
500 + 320 = 820

sorry if you mind but why are you posting all questions here . where are you from
Answer:
Option B) 16 × 9
Option D) 2×2×2×2×3×3
...both are the correct answers.
As a lifeguard, Sara earns a base pay of $80 per day. If her day involves swim instruction, Sara earns an additional $9 per hour, where t represents the number of hours she gives instruction.
Part A: Write an expression to represent how much money Sara earns in a day
Part B: Evaluate your expression to determine how much money Sara earns if she does 7 hours of swim instruction
Answer:
Part A: y = 9t + 80
Part B: $143
Step-by-step explanation:
When solving this question all we need to keep in mind is the fact that if Sarah will not give swim instructions she will get $80 dollars just because she was there as a lifeguard. Then lets think about what will happen when she will work "t" hours? Well, she will get $80 for just being there as a life guard and then on top of that she will get $9t (because she gets $9 every hour she gives instructions). So just now we made an equation that we can use to express how much money Sara earns a day. It can be written mathematically as the following......
Let "y" be the among of money Sara will get paid at the end of the day. then...
y = 9t + 80
In order to answer Part B of this question we will just have to plug 7 instead of "t" into he expression that we made in part A. And so we get .......
y = 9t + 80
y = (9)(7) + 80
y = 63 + 80
y = 143

Consider the equation below.
log.(x+3) = log2 (2+x)
Which system of equations can represent the equation?
Answer:
Option (1)
Step-by-step explanation:
[tex]\text{log}_4(x + 3)=\text{log}_2(2 + x)[/tex]
[tex]\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}[/tex]
[tex]\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}[/tex]
System of equations can be written as,
[tex]y_1=\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}[/tex]
[tex]y_2=\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}[/tex]

10. A ladder 6.5 metres long leans against a wall,
touching a window sill, and makes an angle of
62° with the ground. Find the height of the
window sill above the ground. How far is the
foot of the ladder from the foot of the wall?
Answer:
5.74m, 3.05m
Step-by-step explanation:
The set up is a right angled triangle.
Length of the ladder is the hypotenuse = 6.5m
Angle of elevation = 62°
Required
Height of the window (opposite)
Using SOH CAH TOA trigonometry identity
Sin theta = opp/hyp
Sin62 = opp/6.5
Opp = 6.5sin62
Opp = 5.74m
Hence the height of the window is 5.74m
The distance of the ladder from the foot of the wall is the adjacent
Cos 62 = adj/6.5
adj = 6.5cos62
adj = 3.05m
Hence the distance of the ladder from the foot of the wall is 3.05m

footpath is to be constructed in a park in the shape of a parallelogram. When a coordinate plane is laid over a map of the park, the vertices of the footpath are (−4, 2), (8, 2), (11, 7), and (−1, 7).
Answer:
35.7Step-by-step explanation:
Step one
Given the coordinates
ABCD with vertices A(−4, 2), B(8,2), C(11, 7), and D(-1, 7).
AB=(−4, 2), (8,2)
BC=(8,2), (11, 7)
CD=(11, 7),(-1, 7)
DA=(-1, 7),(-4,2)
The distance between points AB=
[tex]AB= \sqrt (x_2-x_1)^2+(y_2-y_1)^2[/tex]
[tex]AB= \sqrt (8+4)^2+(2-2)^2\\\\AB= \sqrt 12^2+(0)^2\\\\AB= \sqrt144\\\\AB=12[/tex]
The distance between points BC=
[tex]BC= \sqrt (11-8)^2+(7-2)^2\\\\BC= \sqrt 3^2+(5)^2\\\\BC= \sqrt34\\\\BC=5.8[/tex]
The distance between points CD
[tex]CD= \sqrt (-1-11)^2+(7-7)^2\\\\CD= \sqrt -12^2+(0)^2\\\\CD= \sqrt144\\\\CD=12[/tex]
The distance between points DA
[tex]DA= \sqrt (-4+1)^2+(2-7)^2\\\\DA= \sqrt -3^2+(-5)^2\\\\DA= \sqrt34\\\\DA=5.8[/tex]
Hence the perimeter of the footpath= 12+5.8+12+5.8

Answer:
11 cars/day
Step-by-step explanation:
What we know:
After two days, Car-Mart has 43 cars left. After 3 days, it is 32. After five, 10 cars.
Saying that, subtract 32 from 43 to get your rate of 11 cars sold a day.
I can further deduce they started with 76 cars. On day 1 they had 65 cars. On day 4 they had 21 cars. They will have sold all of their cars after day 6.
Over the summer, for every 12 okra seeds Dana planted, 7 grew into plants. If he planted 144 okra seeds, how many grew into plants?
A.
69
B.
84
C.
139
D.
247
Answer:
If Dana planted 144 okra seeds, 84 of those seeds grew into plants.
Explanation:
Image below.
There are okra plants grown from 84 seeds, which is the correct answer would be option (B).
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Over the duration of the summer, 7 out of every 12 okra seeds Dana placed grew plants. He might grow 144 okra plants.
For every 12 okra seeds Dana planted, 7 grew into plants, so the ratio of seeds that grew into plants to seeds planted is 7/12.
Dana planted 144 okra seeds, so the number of seeds that grew into plants is 144 seeds × (7/12) = 84 seeds.
Therefore, 84 okra seeds grew into plants.

Un agricultor tiene una finca de una hectárea la mitad le dedica a cultivar tomates los 2/5 lo dedica a lechugas y el resto cebollas. A qué fracción dedicará cebollas. B qué superficie dedica a cada cultivo.
The given area of the farm, A_0=1 hectare.
The fraction of the farm for cultivating tomatoes = 1/2
The fraction of the farm for cultivating lettuce = 2/5
The remaining fraction of farm for onion = 1-(1/2+2/5)=1/10
Therefore, the fraction of farm dedicated to onion is 1/10.
Now, the area dedicated to tomatoes = 1/2 of the area of land.
=1/2 x 1 = 1/2 hectare.
The area dedicated to lettuce = 2/5 of the area of land.
=2/5 x 1 = 2/5 hectare.
The area dedicated to onion = 1/10 of the area of land.
=1/10 x 1 = 1/10 hectare.
