7400 dollars is placed in an account with an annual interest
rate of 6%. To the nearest year, how long will it take for the
account value to reach 19200 dollars?
Answer:
17
Step-by-step explanation:
We have the following equation for compounding annual interest
AV=PV(1+i)ⁿ
We have
19200=7400(1+.06)ⁿ
Solve for n
divide both sides by 7400
2.594=(1.06)ⁿ
then use the following rule for exponents
[tex]x^y=z\\log_xz=y[/tex]
which means that
[tex]log_{1.06}2.594=n[/tex]
Solve and get
16.362
which rounds to 17

y= 5x + 13
and
y= x + 45
Answer:
x=8 and y=53
Step-by-step explanation:
Given function:
y=5x+13y=x+45Find x:
the two equation, the x and are breaked apart..so find a number that they can both equal to together and has the same y. multiply by 8..[tex]5[/tex]·[tex]8=40[/tex] combine the terms for x and 13[tex]40+13=53[/tex] since x is 8 then if we add 8 with 45 it should be 53...[tex]8+45=53[/tex]y is:
this means that y=53.Therefore, x=8 and y=53..
What is the volume, in cubic cm, of a cylinder with a height of 16cm and a base radius of 3cm, to the nearest tenths place?
Answer:452

Give your answer in the form y=mx+c
Answer:
y = -5x - 5
Step-by-step explanation:
Given the standard form of an equation as y=mx+c
m is the slope
c is the intercept
Using the coordinate points
(1, 0) and (0,-5)
m = -5-0/0+1
m = -5/1
m = -5
Get the intercept
Intercept is the point where thee line cuts the y axis. intercept is -5
Get the equation:
Recall that y = mx+c
y = -5x + -5
y = -5x - 5
This gives the required equation
Can somebody help me with this math question, all you have to do is answer the equation, then it's described, and then it draw it out I'll give you 100 points and a Brainliest

Actually Welcome to the Concept of the integers.
===> -4-7
===> -(4+7)
===> -(11)
====> -11
====> -11 is the answer
Answer:
-11
Step-by-step explanation:
-4 - 7 = -11
subtracting from negatives is like adding
4 + 7 = 11 you just add the negative sign at in front of your answer
-11
HELPPPP I have no idea how to do graphhhsssss
Answer:
Follow the lines
Step-by-step explanation:
Follow what the lines go with what the table has.
To make this really easy, find the slope of the line
To do this you find an easy point.
Ex. x=3 and y= 150
then take it into a slope y-intersept formula
y= mx
150= 3x
50 = x
so for every time x goes up one interval, y increases at a rate of 50.
And for y, do the opposite, for every 50 y, x goes up 1.
By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)
y= 50x is ur slope/formula
(Ill leave the rest for you to answer with this data above ;) )
Hope This Helps :)

8) Jalyn purchased three different sized drinks. The large was twice as much
as the medium drink. The MEGA drink was $10 more than the large. Jalyn
spent a total of $45 on drinks! Write and solve an equation to determine the
cost of the medium drink.
Answer:MARK ME AS BRAINLIEST
MEGA Drink = $10+2x
LARGE Drink = 2x
MEDIUM Drink = x
hence, we conclude that
($10+2x) + 2x + x = $45
$10+2x + 2x + x =$ 45
5x + $10 = $45
5x = $45-$10
5x = $35
x = 35÷5
x = 7
MEGA DRINK = (10+2X)
10+2×7
10+14
24
LARGE DRINK = 2X
2×7 = 14
MEDIUM DRINK = X
7

a. 58* Angle 2 = Angle 4 Angle 1 + Angle 2 = 180*
b. 58* Angle 3 + Angle 4 = 180*
c. 58* Angle 1 = Angle 6
d. 58* Angle 6 = Angle 8
e. 122* Angle 4 = Angle 2
f. 122* Angle 4 = Angle 5
g. 122* Angle 5 = Angle 7
16. Alternate Interior angles. They're equal.
10x - 29 = 8x + 3
2x = 32
Divide by 2 to isolate x
x = 16
double check by putting 16 in for x to see if original statement is true
10 (16) - 29 = 8 (16) + 3
160 - 29 = 128 +3
131 = 131
17. Consecutive interior angles. They equal 180*
13x - 26 + 5x + 8 = 180
18x - 18 = 180
18x = 198
Divide by 18 to isolate x
x = 11
Double check
13 (11) - 26 + 5 (11) + 8 = 180
143 - 26 + 55 + 8 = 180
180 = 180

How do you identify the bases of any prism?
Answer:
Look at the names of the prisms above. Each type of prism is named after its base. In the figure on the left, the base is a rectangle, so it is called a rectangular prism. In the middle, the base is a triangle, so the shape is a triangular prism.

The volume of a cylinder is 471 cm? If the
height is 6 cm, calculate the radius.
Someone plz help
Answer:
Step-by-step explanation:
Formula for volume of a circle: V=πr²
If you multiply the circle by height, it becomes a cylinder.
Formula for volume of a cylinder: V=πr²h
Plug in the numbers and get r by itself:
471 = πr²(6)
Divide both sides by 6:
78.5 = πr²
Divide both sides by π:
25 = r²
Square root both sides:
[tex]\sqrt{25}[/tex] = [tex]\sqrt{r} \\[/tex]²
5 = r
Radius is 5 cm
