Hello and Good Morning! I really really really need some help with these two questions! Thank You!!
Answers
1) A is the correct answer for question 1
A = P(1-r/100)^n
A= amount, P =original cost paid, r= rate of depreciation, n= number of years.
A= 9500(1- 15/100)^7
A= 9500(1-0.15)^7
A= 9500(0.85)^7
A= 9500(0.3205...)
A=3,045.48
Q4 is C
Plug in the values on the bottom row of the table to each of the options & C is the only one that works.

Answer:
b=40/63
Step-by-step explanation:
b= 7. 3b+-4
multiply both sides by 10
b*10=7.3b*10-4*10
refine
b*10=7.3b-40
subtract 7.3b from both sides
b*10-7.3b=7.3b-40-7.3b
simplify
-63b=-40
divide both sides by -63
-63b/-63=-40/-63
simplify
b=40/63

Answer:
x = ± 5Step-by-step explanation:
See the steps
5x^2+8 = 1335x^2 = 133 - 85x^2 = 125x^2 = 125/5x^2 = 25√x² = √25x = ± 5Answer:
x=5
x=−5
Step-by-step explanation:
5x^2+8 =133
Subtract 8 from both sides.
5x^2=133−8
Subtract 8 from 133 to get 125.
5x^2=125
Divide both sides by 5.
x^2=125/5
Divide 125 by 5 to get 25.
x^2=25
Take the square root of both sides of the equation.
x=5

if mr. Wells goes out to dinner and his bill comes to $25.67 and the tax rate is 3.5% how much tax will be added bill
Answers
okay so basically its an increase of 3.5% of 25 dollars and 67 cents.
So
basically
(25.67)* .035 -----> To get .035, you will need to move the decimal to the left twice to make it into a decimal to get the percentage of the total amount.
So the total of that amount would be
89 cents ( ignore numbers after 9 because your just looking at the 2 first number after you did your equation).
Then you add the total amount ( The amount for the meal) + The TAX
So you will get 25.67 + 89 = 26.56
If you got any more questions of what I said ( because it's confusing). Tell me!
ANSWER: $26.56
25.67+0.89= 26.56$
The sum of four consecutive integers is 170. Write an equation that can be used to find the smallest integer.
Answers
Answer:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41
Step-by-step explanation:
Four consecutive integers is represented by:
First Integer = x
Second Integer = x + 1
Third Integer = x + 2
Fourth Integer = x + 3
The sum of four consecutive integers is 170.
x + x + 1 + x + 2 + x + 3 = 170
The Equation to find the smallest integer =
4x + 6 = 170
4x = 170 - 6
4x = 164
x = 164/4
x = 41
Therefore:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41
What is the solution to -2(2x - 3)= 4 - (3x + 5)?
Answers
Answer:
x=7
Step-by-step explanation:
expand -2(2x-3): -4x+6
expand 4-(3x-5): -3x-1
it's now -4x+6=-3x-1
subtract 6 from both sides
-4x+6-6=-3x-1-6
simplify
-4x=-3x-7
add 3x to both sides
-4x+3x=-3x-7+3x
simplify
-x=-7
divide both sides by -1
[tex]\frac{-x}{-1}[/tex]=\ [tex]\frac{-7}{-1}[/tex]

x=7

Answers
Answer:
Possible dimensions are [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex] and [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]
Step-by-step explanation:
Given:
Volume of a cylinder is [tex]64\pi\,\,cm^3[/tex]
To find: Dimensions of a cylinder
Solution:
Let [tex]r,h[/tex] denote height of a cylinder.
Volume of a cylinder = [tex]\pi r^2h[/tex]
Therefore,
[tex]64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h[/tex]
One possible dimension can be [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex].
Also, [tex]64=r^2h[/tex] can be written as [tex]16(2^2)=hr^2[/tex]
So, another possible dimension can be [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]

let there be + black pencils. Thus there are
24 – x coloured pencils. Work in cents.)
of
Answers
Answer:
17 black pencils
Step-by-step explanation:
Cost of black pencils; 15 cents each
Cost of colored pencils; 21 cents each
We are told that 24 pencils cost $4.02 = 402 cents
Let black pencils be x and let colored pencils be y.
Thus;
x + y = 24 - - - (eq 1)
Also,
15x + 21y = 402 - - - (eq 2)
From eq 1, y = 24 - x
Thus putting it in eq 2 gives;
15x + 21(24 - x) = 402
15x + 504 - 21x = 402
504 - 402 = 6x
x = 102/6
x = 17

Please help me, I'm giving away the rest of my points for this 2 part question..
for the second part the answer choices are
A: Right
B: Obtuse
C: Isosceles
D: Equilateral
Answers
Answer:
First part
angle ABC=94 degrees
angle BCD=25 degrees
angle ACB=43 degrees
Second part
C) isosceles and obtuse because angle ABC is greater than 90 degrees and angle ACB=angle CAB
Step-by-step explanation:
All triangles contain 180 degrees.
Triangles ADB and CDB are congruent because side-angle-side theorem.
Since angle ABD=133 degrees, angle CBD=133 degrees because corresponding angles of congruent triangles are equal.
angle ABC=360-133-133=94 degrees
angle BCD=180-133-22=25 degrees
angle ACB=(180-94)/2=43
Angle BCD = 180 - (22+133) = 25 degrees
Angle ACD = (180-44)/2 = 68
Angle ACB = 68-25 = 43 degrees
For the second part, triangle ABC is isosceles
