Answer:
The care is 4 years old
Step-by-step explanation:
V = -2000t + 23,000
15000 = -2000t + 23,000
15000 - 23000= -2000t (+ 23,000 - 23000)
- 8000 = -2000t
- 8000/-2000 = -2000t/-2000
t = 4
Nick and Monica are paid $41.25 for their work. Nick worked 2.5 hours, and Monica worked 3 hours. They split the money according to the amount of time each of them worked.
Nick and Monica are paid $(Blank) for each hour worked. Nick's share of the money is $(Blank)
Answer:
BRIANLIEST PLZ
N = 18.75
M = 22.5
Step-by-step explanation:
Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.
T = t1 + t2 = 2.5 + 3 = 5.5
r1 =2.5/5.5
r2 = 3/5.5
Nick = r1 * 41.25 = 18.75
Monica = r2 * 41.25 = 22.5

A and B are complementary and B and C are supplementary.
9. If mA 48", then mB= ? and mC = ?.
10. If mB 83, then mA = ? and mC = 2.

Find the discriminate, number of roots and solve the quadratic equation using the quadratic formula -my answers are pribably wrong
Answers:
discriminant = dnumber of roots = esolutions = g=================================================
Explanation:
Let's compute the discriminant. Here we have a = 1, b = 1, c = -2
d = b^2 - 4ac
d = 1^2 - 4(1)(-2)
d = 9
The fact that d > 0 tells us we have two different real number solutions.
------------------------
We can use the quadratic formula to solve, or we can factor. I'll use the factor method.
x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x-1 = 0 or x+2 = 0
x = 1 or x = -2
The two solutions are -2 and 1

What is the correct expansion for (x+8)^2
Answer:
Answer: x² + 16x + 64
Step-by-step explanation:
[tex] {(x + 8)}^{2} [/tex]
double the brackets, to remove the power:
[tex] = (x + 8)(x + 8)[/tex]
open the brackets:
Generally:
[tex]{ \boxed{(a + b)(a + b) = {a}^{2} + 2ab + {b}^{2} }}[/tex]
from our equation given;
a » x
b » 8
substitute in the equation in the box:
[tex](x + 8)(x + 8) = {x}^{2} + \{ 2(x)(8) \} + {(8 )}^{2} \\ \\ = {x}^{2} + 16x + 64[/tex]
Answer:
x² + 16x + 64

-3(6b + 4) = 2(-5b+10)
b=
Answer:
b = -4
Step-by-step explanation:
-3(6b + 4) = 2(-5b + 10)
-18b - 12 = -10b + 20
(-18b + 10b) - 12 = (-10b + 10b) + 20
-8b - 12 = 20
-8b (- 12 + 12) = 20 + 12
-8b = 32
-8b/-8 = 32/-8
b = -4

Which of the following best describes the algebraic expression 5(x + 2) - 3 ?
A. Five times a number plus two minus three.
B. Three less than five times a number plus two.
C. Three less than five times the quantity of a number plus two.
D. Five times the quantity of a number plus two less than three.
Answer:
A
Step-by-step explanation:
brackets first according to bodmas
Answer:
C
Step-by-step explanation:
It is not A, that implies that there is no parenthesis needed. Same goes for D.
It is not B, (5x +2)-3
"Three less than" implies that 3 will be subtracted in the end of the equation.
B and C may get mixed up: C includes the phrase "the quantity" which implies the number (x) and two are added before being multiplied by 5.
The sum of 27 and -28 divided by 2.
Hey there!
The word sum usually means addition in mathematics!
27 + (-28) / 2
= 27 - 28 / 2
= -1 / 2
= -0.5
Answer: -1/2 OR -0.5 (either those should work because they are both equivalent)

Okay, so first we need to frame this statement to a numerical expression. It will be :- '27 + (-28) / 2 [sum means to add the 2 numbers, i.e, 27 + (-28). Then we should divide the result by 2 according to the question given.)Now, let's solve it.[tex] \sf\frac { 27 + ( - 28 ) } { 2 } \\ [/tex]
Subtract 28 from 27 to get -1.[tex] \boxed{\boxed{ \boxed{ \bf\frac{-1}{2} = \bf- 0.5}}}[/tex]

The day's high temperature in Phoenix, Arizona was recorded as 104°F. Use the formula C= 5F- -32) to write 104°F as degrees Celsius.
The day's high temperature written as degrees Celsius is lºc.
(Answer quickly)
Answer:
40°C
Step-by-step explanation:
Plug in 104° for F. This makes the equation [tex]\frac{5}{9}(104-32)=C[/tex].
Now, simplify.
[tex]104-32=72\\\frac{5}{9} (72)=40\\C=40[/tex]

A number to be a rational number that is not an integer but a while number
Answer:
So coming back to the question; No, there is no rational number that is not an integer but is a whole number. The number is called as a rational number if it can be expressed as p/q where p & q are integers & q is not 0. All negative integers are rational numbers but those are not whole numbers.Jan 1, 2020
Step-by-step explanation:
If I have 500 and have a 6% annual interest how long will it take to get 2000
Answer:
23.8 years
Step-by-step explanation:
Assuming this is compound interest, we'll use the compound interest formula
A = P(1 + r)ⁿ
A = Final amount (2000)
P = Initial amount (500)
r = Annual interest rate (.06)
n = ?
Our equation will look like this
2000 = 500(1.06)ⁿ
First, divide both sides by 500
2000/500 = (500(1.06)ⁿ)/500
(1.06)ⁿ = 4
Then we have to take the log₁.₀₆ out of both sides
n = log₁.₀₆(4)
n = 23.79132
