Here’s why:
⸻⸻⸻⸻
[tex]2k+9=7-3k\\\rule{150}{0.5}\\\rightarrow 2k + 9 = 7-3k\\\\\rightarrow 2k + 3k + 9 = 7 - 3k + 3k\\\\\rightarrow 5k + 9 = 7\\\\\rightarrow5k + 9 - 9 = 7 - 9\\\\\rightarrow 5k = -2\\\\\rightarrow \frac{5k=-2}{5}\\\\\rightarrow \boxed{k = -\frac{2}{5} = -0.4}[/tex]

We know that February has either 28 or 29 days, but there is a year in the future, February will have 30 days
What exactly is this year?
Answer:
The year 2020 is a leap year, which means February will have 29 days rather than 28, and the overall number of days will be 366 rather than 365. This was also the case in 2016, and the year 2024 will be a leap year once more.

Answer:
1.45 x 10^2
Step-by-step explanation:
In scientific notation, you get the number down to 1 digit before the decimal place and all the rest after it, then multiply by 10 raised to a power in order to get it back to the original. An easy way to do it is to count the number of times you moved the decimal and remember which direction you did it. The number is the power (in this case 2) and the direction tells you if it's positive or negative (in this case it was to the left, so it's positive two.)
In simpler terms, slide the decimal to the right two places and make it 1.45, then multiply it by 10^2 (which is 100) to make it equal to 145. This leaves you with 1.45 x 10^2.

3. 23.4
Step-by-step explanation:
1. 7.921 * 10^4
10 ^ 4 = 10000
move the decimal point four places to the right
= 79,210
2. 6.231 * 10^3
10 ^ 3 is 1000
move the decimal point three places to the right
6,231
3. 0.234 * 10^2

Answer:
Step-by-step explanation:
I know this is rather sneaky, but on a multiple choice question on a quiz, you need all the help you can get. I'm not saying this is a quiz, by the way. It doesn't say that it is anywhere.
Look carefully at the first three statements. Is there an angle mentioned at all? There isn't, is there? That being the case (and since nothing is marked as a right angle), the only possible answer is SSS which D.
Answer:
D
Step-by-step explanation:
There are not any angles shown, and the triangle is not a right triangle, so it is SSS

What is the length of ef in the right triangle below?
Answer:
24
Step-by-step explanation:
You're given a side and a hypotenuse in a right triangle, so you're able to use the Pythagorean Theorem.
[tex]a^{2} + b^{2} = c^{2}\\\\a^{2} + (7)^{2} = (25)^{2}\\[/tex]
Now isolate a on one side and solve for a.
[tex]\\a^{2} = (25)^{2} - (7)^{2}\\\\a = \sqrt{(25)^{2} - (7)^{2}} \\\\a = 24[/tex]

Answer:
point
Step-by-step explanation:
the dot has no connectives or no paths
The best describes the geometric figure is a point. SO option B is correct.
What is a line segment?A line segment is a part of a line that connects two points which are considered to be its endpoints.
If points A and B are connected by a series of points that extended infinitely in opposite direction then AB is a line.
Therefore, The best describes the geometric figure is a point. SO option B is correct.

Answer:
C) is correct answer
Step-by-step explanation:
In pic
(Hope this helps can I pls have brainlist (crown)☺️)
The equation y = 35x +25 represents the linear relationship between y, the total charges in dollars, and x, the number of hours the mechanic worked.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The given table shows the relationship between the total charges and the number of hours worked by the mechanic.
Number of hours worked, x Total charges, y
1 60
2 95
3 130
4 165
Let the equation for this relationship:
y = mx + c ....(i)
From the table, we can see that the mechanic charges an initial fee of $60, and then an additional $35 for each hour worked.
Here, m = {(95-60)/(2-1)} = 25
60 = 25(1) + c
c = 60 - 25 = 35
So, the equation is y = 25x + 35
Therefore, the equation y = 35x +25 represents the linear relationship.

Answer:
A rotation 90° CW followed by translation right 5 units.
Step-by-step explanation:
It is easier to choose the right composition of transformations if we know what your choices are.
Figure F has an orientation that is 90° CW from that of figure E, so a 90° CW or 270° CCW rotation could be one of the transformations.
Rotation about the origin will move the figure so that the acute angle is in a different quadrant. In order to return it to the same quadrant a translation is required. The amount of translation will depend on whether it comes before or after the rotation.
Possible sequence of motions are ...

We see angles P and R marked to be same with P having the angle measure indicated.
We assume the Q is the right angle, otherwise the given info is not enough to find the answer.

The angle x is partitioned as:
Right angle and two complementary angles, one with P and one with R.Then its measure is:

Answer: They would travel 17.25 miles in 23 minutes and 45 miles in 1 hour.
Step-by-step explanation:
If you divide 1 3/4 by 2 1/3 you get. 0.75 which is how far the car will travel each minute and then you can just multiply that number by however many minutes there are.

Answer:
Step-by-step explanation:
This is a problem of ratios:
Set the problem up with matching similar side lengths equal:
50/10 = x/12
First simplify the left side:
50/10 = 5
Next, multiply both sides by 12.
We are left with:
x = 12(5)
x = 60
