Answer:
C
Step-by-step explanation:
The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

There are 40 people in a room. The ration of men to women is 2:3. If 5 more men enter the room, what will the new ratio be?
Answer:
16:29
Step-by-step explanation:
2u+3u=5u
40/5=8
Each unit represents 8 people
Hence, number of women:
8 x 2= 16
Number of men:
8 x 3 =24
New number of men:
24 + 5 = 29
New ratio:
16:29
Answer:
7 : 8 (men to women)
Step-by-step explanation:
Ratio = 2 : 3 (men to women)
40 people in all
40 / 5 = 8
2 x 8 = 16 (men)
3 x 8 = 24 (women)
16 + 5 = 21
21 : 24
7 : 8

When a construction worker is on a platform 10 feet above the ground, we can describe her elevation as +10 feet.
A construction worker digs down to 30 feet below the platform. What is her elevation?
It is 30 feet BELOW the platform, so the number is -20 because the platform is 10 feet above ground level.
Her elevation is - 20 because she is 10 feet above ground level, which is 10, and she digs 30 feet down so 10 - 30 is -20.
Hope this helps. :)
Answer:
-20 feet
Step-by-step explanation:
Ok, if the construction worker is first at 10 feet above the ground. If the construction worker goes 30 feet below the platform, the equation can be this: 10 - 30 = e or elevation. Remember that it states that the construction worker digs 30 feet below the platform, and not below the ground. Because 10 - 30 is -20, we know that the construction worker's elevation is -20.
I hope this helps :)

step-by-step explanation:
original coordinates of B: (-9, -8)if reflected over y-axis, use the formula: (x, y) → (-x, y)
new coordinates: (-(-9), -8) → (9, -8)The city of newport is expecting a budget deficit this year of $257,943, which is 30% less than last year. what was last year's deficit?
last year deficit x 0,70 = 257,943
so
last year deficit = 368,490
- 30% = x (1 - 30%) = x 0,70
The temperature in a room at midnight is 20 degrees Celsius. Over the next 24 hours, the temperature changes at a rate modeled by the differentiable function H, where H(t) is measured in degrees Celsius per hour and time t is measured in hours since midnight. Which of the following is the best interpretation of 0 6 H(t) dt?
(A) The temperature of the room, in degrees Celsius, at 6:00 A.M.
(B) The average temperature of the room, in degrees Celsius, between midnight and 6:00 A.M.
(C) The change in the temperature of the room, in degrees Celsius, between midnight and 6
(D) The rate at which the temperature in the room is changing, in degrees Celsius per hour, at 6:00 A.M.
It will represent the change in temperature between midnight and 6, the correct option is C.
Which is the best interpretation of ∫H(t)*dt?
H(t) is the rate at which the temperature changes. So, if we integrate H(t), we will get the change of temperature.
In this case, we have:
[tex]\int\limits^6_0 {H(t)} \, dt[/tex]
This will give the change in temperature between 6:00 AM (represented by the 6) and midnight (represented with the 0).
So the correct option is C.

In a certain town there were 171 robberies last year. This year the number of robberies has gone down 39%. How many robberies were there this year, to the nearest whole number?
Answer:
104 robberies
Step-by-step explanation:
No of robberies last year = 171
Robberies for this year reduced by 39%
Percentage robberies of this year reduced to 39%
39% * 171
= 39/100 * 171
= 66.09
That is to say that this year robberies reduced by 66.09
Therefore this year robberies = 171 - 66.09
= 104.31
= 104 to the nearest
whole number

An algebra tile configuration. only the product spot is shown. 9 tiles are in the product spot in 5 columns with 5 rows. first row: 1 x squared, 4 x. below the x squared tile are 4 x tiles. which value is needed in the expression below to create a perfect square trinomial? x2 8x ______ 4 8 16 64
We need 16 in the given expression to create a perfect square trinomial.
Let us say the given expression is:
[tex]x^{2} +8x +k^2[/tex]...............(1)
We can rewrite the above expression as:
[tex]x^{2} +2*x*4 +k^2[/tex].........(2)
What is (a+b) squared?The square of a+b is a²+2ab+b².
If we compare (2) with [tex]a^{2} +2ab+ b^{2}[/tex]
We get, a =x, b = 4 and k²=b²
Since b=4
So, k² =4²
k² =16
Put the value of k² in (1)
We get the expression [tex]x^{2} +8x +16[/tex]
Therefore, We need 16 in the expression [tex]x^{2} +8x+....[/tex]to create a perfect square trinomial.

The error Luke made when trying to use Cavalieri's principle to show that the two figrues have the same volume is stating that: "corresponding cross-sections have the same area" which is NOT TRUE.
What is the Cavalieri's Principle?The Cavalieri's principle was named after Bonaventura Cavalieri. The Cavalieri's principle states the volume of two figures are the same if they have the same height and teh same cross-sectional area at every point along the height.
Thus, the two figures have entirely different cross-sectons. Their areas would be diffrent.
