Answer:
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0
Step-by-step explanation:
At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.
We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.
43.7°F is above 0 and 3.6°F is below 0.
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).

The length of Line segment VZ is 10 units if Z is the circumcenter of triangle TUV. Point Z is the circumcenter of triangle T U V option (D) 10 units is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
In the diagram, Z is the circumcenter of the triangle TUV. Point Z is the circumcenter of triangle T U V.
As we know, The vertices of a triangle are equidistant from the circumcenter.
VZ = UZ = TZ
UZ = 3x + 4
TZ = 5x
3x + 4 =5x
5x - 3x =4
2x = 4
x = 2
TZ = 5x = 5(2) = 10 units
Thus, the length of Line segment VZ is 10 units if Z is the circumcenter of triangle TUV. Point Z is the circumcenter of triangle T U V option (D) 10 units is correct.

5x+6 = -9
Answer:
The correct answer is D, "Multiplication Property of Equality"
Step-by-step explanation:
This is because in the original equation it shows, 5/3x + 2 = -3, then you multiply by 3 to get rid of the 5/3, and on the other side you get -9.

Step-by-step explanation:
If the cost of a competing factor of production, such as a machine that also could do the job, rises. This would result in a shift in the demand for this factor out to the right and would put pressure on the wage to rise. I don't understand why this is the case because I thought if machines replaced human labor then wouldn't wages be lower because there wouldn't be a need for human labor?
Keep in mind that we're framing it based on what the first sentence says, which is "If the cost of a competing factor of production, such as a machine that also could do the job, rises".
So if the cost of getting a machine part, various parts, or the entire machine cost rises, then demand for the machine will go down. This will make employers seek out substitutes. In this case, those substitutes would be human labor. As employers demand for labor goes up, the wages will rise assuming the supply of workers is held constant. If the supply of workers increased, then you could argue the wages could go down. So that's why I'm assuming the supply is held in check.

1. Calculate the federal income taxes. In 2018, the federal income tax was 10 percent on incomes between $0 and $9,525 per year, 12 percent on incomes between
$9,526 and $38,700, and 22 percent on Incomes between $38,701 and $82,500. In 2018, you made $42,000. What was your income tax this year?
O $5,040
$8,400
$4,200
$9,240
Answer:
$9,240.
Step-by-step explanation:
Given that in 2018, all salaries between $ 38,701 and $ 82,500 had to pay a federal income tax of 22%, and that my salary in that year was $ 42,000, to determine the amount that I had to pay in concept of said tax, the following calculation must be done:
(42,000 x 22) / 100 = X
924,000 / 100 = X
9,240 = X
Therefore, the amount of federal income tax that I had to pay in 2018 was $ 9,240.

1) The original price of the shorts is $35. They are on sale for 25% off. a) What is the discount amount? b) What is the sale price?
Answer:
26.25
Step-by-step explanation:
Answer:
A. $8.75 B. $26.25
Step-by-step explanation:
To figure this out, multiply .25 by 35 to find out what 25% of 35 is. The answer is $8.75, meaning that the shorts are $8.75 cheaper than the original price.
To find the on sale price, subtract $8.75 from $35. The answer is $26.25, meaning that the on sale price is $26.25.

y = -1.5x + 33.8
Step-by-step explanation:
The y is how much is left. every time she washes her hair, she loses 1.5. So the x can be filled in by any number to get the answer. Ex: y = -1.5(4) + 33.8. Now you multiply -1.5 by 4 and get -6. Now you have Y = -6 + 33.8. And solve from there. Pls mark brainliest is this helped

In this question, a condition is defined, that checks the given condition, which is 1>=2, in this condition and if block is used, when the condition is true, it will print the true message, otherwise, it will go to the else block, in which, it will print the false message.
In a two-digit number, the first digit is 5 less than the second digit. The number itself is three times the sum of its digits. What is the number? (I WILL MARK BRAINLIEST)
Answer:
27
Step-by-step explanation:
taking the second digit as 'x'
as per question the first digit is 'x-5'
therefore putting this in the one, tens, hundreds form
u multiply the first digit by 10 and the second by 1
therefore,
10(x-5) + 1(x)
now you have that the 2-digit number is equal to twice the sum of the digits,
so
10(x-5) + 1(x) = 3 [ (x-5) + (x) ]
on solving
10x - 50 + x = 3 (2x - 5)
11x -50 = 6x - 15
taking 6x on the right and -50 on the left
11x - 6x = 50 - 15
5x = 35
therefore x = 7
now substituting this value we get that the number is

Paulo identifies one point on a line as (6,3), and he knows that the slope is 2. How can he derive the equation of the line
Answer:
y = 2x + 3
Step-by-step explanation:
Points (6,3) are x,y coordinates.
Use slope intercept form: y = mx + b
b = y intercept
m = slope
The equation that has a slope of 2 and passes through (6, 3) will be y = 2x - 9.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the equation is 2. Then the equation is given as,
y = 2x + c
The line is passing through (6, 3), then we have
3 = 2(6) + c
3 = 12 + c
c = 3 - 12
c = - 9
The equation will be given as,
y = 2x - 9
The equation that has a slope of 2 and passes through (6, 3) will be y = 2x - 9.

The product of two consecutive even integers is 8. Find the integers.
Note: each set of brackets represents one solution.
Answer:
-4 and -2
2 and 4.
Step-by-step explanation:
Let n be the first even integer.
Then the consecutive even integer will be represented by (n+2).
We know that their product is 8. So:
[tex]n(n+2)=8[/tex]
Solve for n. Distribute:
[tex]n^2+2n=8[/tex]
Subtract 8 from both sides:
[tex]n^2+2n-8=0[/tex]
Factor:
[tex](n+4)(n-2)=0[/tex]
Zero Product Property
[tex]n+4=0\text{ or } n-2=0[/tex]
Solve for n for each case:
[tex]n=-4\text{ or } n=2[/tex]
Hence, we will have two correct solutions.
Case 1: -4 and -2. -4(-2) is indeed 8.
Case 2: 2 and 4. 2(4) is also 8.
Hence, our solutions are:
-4 and -2
2 and 4.

Draco invests $5000. Approximately how long will it take for the investment to double if the rate is 10% compounded annually?
Answer:
I'm in 6th grade and I think it is 500
For the investment to double if the rate is 10% compounded annually,
it will take about 7 years and 3 months.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n[tex])^{nt}[/tex]
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for.
Given:
Draco invests $5000.
Draco wants his investment to double.
That means, accrued amount = $10000
Interest rate = 10%
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 per year,
Then, by using the formula,
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )
t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )
t = 7.273 years
t = about 7 years 3 months
Therefore, the required time is about 7 years 3 months.
