NO
YES
Answer:
i dont think so
Step-by-step explanation:
Answer:
No, because you're just solving it as you are doing an equation
Step-by-step explanation:
8y < (-40)
Divide both sides by 8
8y/8 < (-40)/8
Simplify
y < -5

An architect is designing a school courtyard that is 45 feet long and 30 feet wide. What will be the measurement of the drawing? Use a scale of 0.5inch = 10 feet. \\\
Answer:
L= 2.25 in
W= 1.5 in
Step-by-step explanation:
Step one:
given
The dimension of the courtyard is 45 feet long and 30 feet wide
Required
The measurement of the drawing given the scale 0.5inch = 10 feet.
Step two:
1. The length of the drawing
if 0.5 in represents 10 ft
then x in will be 45ft
cross multiply
45*0.5= 10x
22.5=10x
divide both side by 10
x= 22.5/10
x=2.25in
2. The width of the drawing
if 0.5 in represents 10 ft
then y in will be 30ft
cross multiply
30*0.5= 10y
15=10y
divide both side by 10
y= 15/10
y=1.5in

Answer:
40/33
Step-by-step explanation:
x=1.21 (21 repeating)
100x=121.21 (21 repeating)
100x-x=121.21-1.21
100x-1x=(121+0.21)-(1+0.21)
99x=120+0
99x/99=120/99
x=40/33

John bought a box of popcorn for $3.50 and three medium drinks. Define a variable and write an expression to represent the total amount he spent. Then find the total amount of one drink cost $ 1.50
Answer: $8.00
Step-by-step explanation:
Let the cost of medium drinks be represented by d.
Therefore, the expression to represent the total amount that he spent will be:
= 3.50 + 3d
Total amount will then be:
= 3.50 + 3d
= $3.50 + 3($1.50)
= $3.50 + $4.50
= $8.00

Step-by-step explanation:
which equation represents the vertical line passing through (1.-9)?
OA
OB
x=1
OC. y=-9
OD
y=1
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
The point is [tex](1,-9)[/tex]. This means the value of [tex]x[/tex] is [tex]1[/tex] and value of [tex]y[/tex] is [tex]-9[/tex].
Vertical line means that the point has the value of [tex]y[/tex] axis as zero [tex](0)[/tex].
Since, the point has [tex]x[/tex] value [tex]1[/tex] the vertical line passing through it will be [tex](1,0)[/tex] which means [tex]x=1[/tex].
i dont know what 12 / 63(fraction) is simplified can someone help
also 12 isn't 1
Answer:
[tex]\frac{4}{21}[/tex]
Step-by-step explanation:
When simplifying fractions, you need to find the biggest common factor between the numerator (12) and denominator (63). In this case, the biggest common factor is 3.
Thus:
Numerator = 12 ÷ 3
= 4
Denominator = 63 ÷ 3
= 21
[tex]\frac{12}{63}[/tex] = [tex]\frac{4}{21}[/tex]

Ted invests $8,310 in a savings account with a fixed annual interest rate of 2% compounded continuously. How long will it take for the account balance to reach it take for the account balance to reach $9,751.88?
Answer: It will take 8 years.
Step-by-step explanation:
Equation for interest compounded continuously:
[tex]A=Pe^{rt}[/tex] , A = accumulated amount , P=Principal value , r =rate of interest , t= time.
Given: P= $8,310 , r = 2% , A= $9,751.88
[tex]9751.88=8310e^{0.02t}\\\\\Rightarrow\ \dfrac{9751.88}{8310}=e^{0.02t}\\\\\Rightarrow\ 1.17351143201=e^{0.02t}[/tex]
Taking natural log on both sides
[tex]\ln (1.17351143201)=\ln (e^{0.02t})\\\\\Rightarrow\ 0.160000478068=0.02t\\\\\Rightarrow\ t=\dfrac{0.160000478068}{0.02}\\\\\Rightarrow\ t=8.0000239034\approx8[/tex]
Hence, it will take 8 years.
A rectangular piece of land measures 20 feet by 15 feet. James created a cement sidewalk, x feet wide, to border a rectangular garden on all four sides as shown below.
If the garden has an area of 150 square feet, how wide is the sidewalk?
A
12.25 feet
B
6.12 feet
C
5 feet
D
2.5 feet
Answer:
The second and fourth answer are correct
Step-by-step explanation:
The width of the sidewalk if A rectangular piece of land measures 20 feet by 15 feet, James created a cement sidewalk, x feet wide, is 12.25 so, option A is correct.
What is the area?An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.
Given:
A rectangular piece of land measures 20 feet by 15 feet, James created a cement sidewalk, x feet wide,
the garden has an area of 150 square feet,
Calculate the width of the sidewalk as shown below,
Area of rectangular piece = area of garden + area of sidewalk
20 × 15 = 150 + x × x
300 = 150 + x²
x² = 300 - 150
x = √150
x = 12.25
Thus, the width of the sidewalk is 12.25 feet.

Answer:
9.13
Step-by-step explanation:
Solve the system by substitution x=9y and x-5=20
Answer: y=2.7
Step-by-step explanation:
Since x=9y and substitution,
plug the 9y in where x is in the equation like so,
9y-5=20
Now get the variable by itself
To do this you add 5 to both sides of the equal sign
5+(-5) cancels out and 20 +5 =25
Now isolate the varaible by dividing 9y from both sides
So, 9y=25
9/9=1 so you leave it as y
and 25/9 is 2.77777
therefore y=2.7

Mike is 5 years older than David. Four times David’s age increased by three years equals three times Mike’s age decreased by two years. Find Mike’s age.
Answer:
15 years
Step-by-step explanation:
Write as an algebraic equation-
D+5=M
4D+3=3M-2
substitute
4D+3=3D+15-2
4D+3=3D+13
subtract 3 and 3D
D=10
Plug in D
10+5=M
M=15
I am trying to get the value of imaginary numbers. The expression is [tex]i^2[/tex]
and now if I evaluate it like this,
[tex]i^2 = (\sqrt{-1} )^2\\= -1[/tex]
I get -1
Again, if I evaluate it like this,
[tex]i^2 = i \times i\\= \sqrt{-1} \times \sqrt{-1}\\= \sqrt{-1 \times -1}\\= \sqrt{1}\\= 1\\[/tex]
I get 1
So there are two values -1 and 1. Which one is correct? If either of these two is incorrect, why?
Obviously 1 ≠ -1, so both conclusions cannot be true.
The short answer is that √(ab) = √a √b is always true if a and b are both non-negative integers, but not always true otherwise. The case here is one in which the identity does not apply. "√a" literally means "the positive number such that its square is a". But you're using the convention that √(-1) = i, and i is not a positive number, so this identity does not apply.
The correct result is i ² = -1.
That's not to say that the identity above is always wrong whenever a or b are not non-negative. For example,
√(-25) = √((-1) × 5²) = √(-1) × √(5²) = 5i
is y=8200(1.19)x a growth or decay and what is the percentage
Answer:
Growth 119
Step-by-step explanation:
It is positive and the percentage is 1.19 with the decimal moved 2 places to to the right.
Answer:
Answer is 19%
Step-by-step explanation:
The girl/boy above answered it right but they added an extra 1! Poor dudes who got this wrong! But its actually increase by 19%!
y=8200(1.19)
y=a(1+r)^x
y=8200(1+0.19)^x
r=0.19
That means its an 19% INCREASE! Hope this helped this info is STRAIGHT OFF THE BACK FROM DELTA MATH! So this IS correct! Hope this helped my loves! Hit that star and that heart button if this helped you out! So other people can see this answer is correct! :P
