Step-by-step explanation:
A small town has two local high schools. High School A currently has 850 students and is projected to grow by 35 students each year. High School B currently has 700 students and is projected to grow by 60 students each year. Let AA represent the number of students in High School A in tt years, and let BB represent the number of students in High School B after tt years. Write an equation for each situation, in terms of t,t, and determine after how many years, t,t, the number of students in both high schools would be the same.
An equation for each situation, in terms of t, is y = 850e^35t and
y = 700e^70t
The required equation will be in the form y = Ae^kt
where:
k is the growth constantA represents the number of students in High School A in t years.B represents the number of students in High School B after t years.If High School A currently has 850 students and is projected to grow by 35 students each year, hence;
A = 850k = 35 (growth factor)Substituting into the formula, we will have:
y = 850e^35t
If High School B currently has 700 students and is projected to grow by 60 students each year, hence;
A = 700k = 60 (growth factor)Substituting into the formula, we will have:
y = 700e^70t
An equation for each situation, in terms of t, is y = 850e^35t and
y = 700e^70t

Answer:D
Step-by-step explanation:
anna is working two summer jobs, making $11 per hour tutoring and $15 per hour clearing tables. anna must earn at least $230 this week. write an inequality that would represent the possible values for the number of hours tutoring, t, and the number of hours clearing tables, c, that anna can work in a given week
Answer:
Step-by-step explanation:
Money earned by tutoring for 't' hours = 11 * t = 11t
Money earned by clearing tables for 'c'hours = 15 * c = 15c
11t + 15c ≥ 230

What is the slope indicated in the table below?*
X. 8 6 4 2
Y. 2 4 6 8
Answer:
-1
Step-by-step explanation:
in order to find the slope you need to look at the change in x over the change in y. x is decreasing by 2 every time, and y is increasing by 2. you now have -2/2 simplify and you get -1
Need answer for this.
Answer:
The equation of the line is y = (5/2)x + 5.
Step-by-step explanation:
When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :
y = (5/2)x + b
let x = -2, y = 0,
0 = (5/2)(-2) + b
0 = -5 + b
b = 5
Answer:
y=5/2x+5
Step-by-step explanation:
Since both lines are parallel they have the same slope. From y=5/2x+1, the slope is 5/2
The equation of the line passing through (-2,0) using slope intercept form is
y-y1=m(x-x1)
y-0=5/2(x--2)
y=5/2(x+2)
y=5/2x+5

An angle measures 12° less than three times it’s supplement. Find the measure of the angle
Answer:
132 degrees.
Step-by-step explanation:
Let the supplement be x and the angle be y.
x + y = 180 degrees.
y = (3x - 12) degrees.
x + 3x - 12 = 180
4x = 192
x = 48 degrees
y = 132 degrees

The height of cone is 7 m
what is height of cone?A cone is a three-dimensional shape, formed by using a set of line segments or the lines which connect at a common point, to all the points of a circular base.
The cone height formula helps in calculating the distance from the vertex of the cone to the cone's base. The height of the cone can be calculated using either the volume of cube and radius or with slant height and radius of the cone.
Cone Height Formula for Cone can be expressed as,Formula 1: h = 3V/πr2
where,
V = Volume of the cone
r = Radius of the cone
This formula is derived from the formula of the volume of a cone.
Given:
d= 12 m
Volume = 264 m.
volume = πr²h
264= 1/3x6x6x3.14 * h
264 = 37.68 * h
h= 264 / 37.68
h= 7 m

High School B rented and filled 12 vans and 10 buses with 600 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
please show you work
Answer:
10 students/van
48 students/bus
Step-by-step explanation:
(a) 13v+5b = 370
(b) 12v+10b = 600
(a) - (b)
v -5b = -230
v = 5b-230
12(5b-230) + 10b = 600
60b+10b -2760=600
70b=3360
7b=336
b=48
v = 5(48) - 230 = 10
v = 10
