Given that,
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.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.
round 75.0794 to 2 decimal places
Answer:
75.08
Step-by-step explanation:
Focus on the 2nd digit to the right of the decimal point (it is 7). The next digit is 9. Because of this (nex digit 5 or greater), we round the 7 up to 8 and obtain the answer
75.08
Find three consecutive even integers such that the sum of the smallest integer and twice the second is 12 more than the third
Answer:
6, 8 , 10
Step-by-step explanation:
smallest = x
medium = x+2
largest = x+4
The smallest integer and twice the second is 12 more than the third:
x + 2(x+2) = 12+ (x+4)
x + 2x + 4 = x +16
3x + 4 = x + 16
2x = 12
x = 6

Is 1.888... an irrational number? (i have a 1 in math :C)
Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.
what value of x makes the equation true 2( x + 10) =4( 2x - 1)
Answer:
6
Step-by-step explanation:
Step-by-step explanation:
Answer:-[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]
We need the value of x. So, we will break the brackets first.

The highest point in Argentina is 6,960 meters above sea level. The lowest point is 105 meters below sea level. What is the difference between the highest and lowest points?
Answer:
7,065 meters.
Step-by-step explanation:
The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:
[tex]6960-(-105)=x[/tex]
When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:
[tex]6960+105=7065[/tex]
There is a 7,065 meter difference between the two points.

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute
Answer:
$3
Step-by-step explanation:
To find the value of the tip, multiply 200 by 15%.
200 x 15% = 30
Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)
30 / 10 = 3
Each person should contribute $3 toward the tip.
Each person will contribute $23.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Bill= $200
Tip= 15%
So, the amount of bill be paid after tip
= 200+ 200 x 15%
= 200+ 200 x 15/100
= 230
Now, each of them have to pay
= 230/ 10
= $23
Hence, Each of them paid $23.

Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.
100, 105, 110.25, ...
Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?
A. f(n + 1) = f(n) + 5
B. f(n + 1) = 5f(n)
C. f(n + 1) = 1.05f(n)
D. f(n + 1) = 0.05f(n)
1.05 should be it
Step-by-step explanation:
In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.
To find this common ratio, we find the percent of change between terms. We do this by using the formula
% change = (amount of change)/(original amount)
The amount of change between the first two terms is 105-100 = 5. This makes the percent change
5/100 = 0.05
The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change
5.25/105 = 0.05
However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.
This gives us the recursive formula
Answer:

Answer:
I think it's the third choice because line segments are congruent and not equal. Line segments also have little lines on top of the letters.
Step-by-step explanation:
======================================================
Explanation:
AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.
So this is why choice A is one of the answers.
[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.
This is why choice C is the other answer.
--------------
Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.
