create a tangent to a circle. (use your digital tool, compass, or a loose sheet of paper to help you keep your lines and points of contact precise).
Answer:
I think you have to draw a circle then draw a line that goes parralel to one tiny part of the circle. this ensures it only touches the circle at one place. make sure the line is straight too!
In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 14 B. 113 C. 17 D. 48
Answer:
The number of heating degree days is 17 (option c).
Step-by-step explanation:
You know that the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
You know that the high temperature for a day was 51°F and the low temperature for the same day was 45°F.
The mean, also called the average or arithmetic mean, is a measure of central position. In general, the average is calculated by adding all the figures or values presented and dividing them by the total number of values. So, in this case, the average of the high and low temperatures for the day is:
[tex]\frac{51 F + 45 F}{2}= 48 F[/tex]
The number of heating degree days can be calculated by:
H= 65°F - 48°F
H= 17 °F
The number of heating degree days is 17 (option c).

write a quadratic function f whose only zero is 7
well, we know is a quadratic, namely of degree 2, so it has two solutions and namely two factors, and whose only zero is 7, well, we can do that by giving that only zero a multiplicity of 2, so we get two of the same zero.
[tex]\begin{cases} x=7\implies &x-7=0\\ x=7\implies &x-7=0 \end{cases}\qquad \implies \qquad \begin{array}{llll} \stackrel{\textit{multiplicity of 2}}{(x-7)(x-7)}=\stackrel{0}{y} \\\\\\ x^2-14x+49=y \end{array}[/tex]
The quadratic function would be x² + 14x + 49 f whose only zero is 7.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
The standard quadratic function is given by ax² + b x + c = 0.
We know that is a quadratic of degree 2, so it has two solutions and two components, and its only zero is 7,
⇒ x = 7 and x = 7
⇒ x - 7 and x - 7
Thus, we can accomplish that by multiplying that singular zero by two, so we obtain two of the same zero.
⇒ (x - 7)(x - 7)
⇒ (x - 7)²
⇒ x² + 7²+ 2 × 7 × x
⇒ x² + 49 + 14x
⇒ x² + 14x + 49
Therefore, the quadratic function would be x² + 14x + 49.

Correct Question
A dentist is making identical dental care bags for patients using 56 tubes of toothpaste, 112 packets of floss, and 84 toothbrushes. What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover? Describe the contents of each bag.
Answer:
What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover?
28 identical dental care bags
Describe the contents of each bag.
2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.
Step-by-step explanation:
We solve for this using greatest common factor method
Step 1
Find the factors of 56, 84 and 112
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 112 are: 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
The greatest common factor amongst them is = 28
Hence, the greatest number of identical dental care bags the dentist can make with the least amount of items leftover is 28 bags.
Describe the contents of each bag.
Each bag should contain 2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.

if p varies inversely as the square root of q, and p=12 when q=36, find p when q=16
Answer:
Step-by-step explanation:
p = k / sqrt(q)
The first job is to find k.
p = 12
q = 36
Solution for k
12 = k / sqrt(36)
sqrt(36) = +/- 6
Multiply both sides by +/-6
12 * +/- 6 = k
k = +/- 72
Solution for q = 16
p = +/-72/ sqrt(16)
p = +/- 72 / sqrt(16)
p = +/- 72 / +/-4
p = 18
For his phone service, Hong pays a monthly fee of $30, and he pays an additional $0.07 per minute of use. The least he has been charged in a month is $124.92.
What are the possible numbers of minutes he has used his phone in a month?
Use m for the number of minutes, and solve your inequality for m.
Answer:
First, let's set up the equation
· We know the least total he's got in one month is $124.92
· In that one month, he was charged an additional $30 dollar fee.
· During the time he uses his phone, he is charged $0.07 per unknown minutes (which we can consider 'm').
It would look like this;
30 + 0.07m = 124.92
where $30 is the additional fee
$0.07 is the money he is charged per unknown minutes otherwise known as 'm'
$124.92 is the total of that whole month (which has been the least amount of money he used)
So now we solve for m:
30 + 0.07m = 124.92
-30 -30(get rid of any constants first by performing the inverse operation of addition, subtraction)
0.07m = 94.92
/0.07 /0.07 (isolate 'm' by applying the inverse operation of multiplication, division)
m = 1,356 minutes
One brand of juice contains 0.05 of natural juice. Which is this decimal written as a percent?
A) 0.05%
B) 5%
C) 0.5%
D) 50%
Answer:
B.) 5%
Step-by-step explanation:
You'll need to multiply 0.05 by 100. Since 100 = 1, we are only multiplying by 1 and not changing the value of our number.
0.05 × 100 = 5
5/100 is 5 over 100 and means 5 per 100. 5 "per 100" means 5 "percent" or 5%
Therefore, 0.05 = 5%

Lauren has gross pay of $765 and federal tax withholdings of $68. determine lauren's net pay if she has the additional items withheld: social security tax that is 6.2% of her gross pay medicare tax that is 1.45% of her gross pay state tax that is 22% of her federal tax a. $691.52 b. $666.21 c. $636.98 d. $623.52 please select the best answer from the choices provided a b c d
Lauren's net pay after deductions will be equal to $623.52
What will be the net pay of Lauren?The net pay of the Lauren will be calculated as
The gross pay is = $ 765
The Federal tax = $68
Social security tax on gross pay 6.2%= [tex]SST=765\times 0.062=47.43[/tex]
Medicare tax on gross pay 1.45%= [tex]765\times 0.0145=11.09[/tex]
State tax on federal tax holdings 22% =[tex]68\times 0.22=14.96[/tex]
Now the net pay will be
[tex]=765-68-47.43-11.09-14.96=623.52[/tex]
Thus Lauren's net pay after deductions will be equal to $623.52

Given the equation y= -3x+2.5, when y is 8.5, what value of x makes the equation true?
PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER AS WELL !! ( im not very smart :c )
Answer:
x= -2
Step-by-step explanation:
First, write your equation with 8.5 substituted for y: 8.5= -3x +2.5
Next, subtract 2.5 from both sides to simplify the equation: 6= -3x
After that, divide both sides by -3 to get x by itself: -2 = x
So, when y=8.5, x=-2.

At a concert, tickets cost either $40 or $60. 700 tickets were sold at a cost of $33600. Find how many $40 tickets were sold.
Answer:
420
Step-by-step explanation:
Let x = number of $40 tickets.
Let y = number of $60 tickets.
x + y = 700
40x + 60y = 33600
-40x - 40y = -28000
20y = 5600
y = 280
x + y = 700
x + 280 = 700
x = 420
Answer: 420 $40 tickets were sold
