Find the value of x.
Answer:
x = 117
Step-by-step explanation:

Please help! 10 points! It costs $60 to rent a car for a day, and each mile you drive costs $40. Write an expression for the daily cost to rent the car and drive D miles. How much will it cost if you drive 37 miles?
Answer:
$1540
Step-by-step explanation:
base cost = $60
1 mile = $40
$40 x 37m = $1480
$1480 + $60
= $1540

OD. The x-intercept is (1,0).
O E. It is increasing.
O F. The domain of F(x) is x > 0.
Answer:
A, B, and C
Step-by-step explanation:
The solution is, The true statements are F and E.
i.e. F. The x-intercept is (1,0).
E. It is increasing.
What is a log function?The logarithm can be stated as the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x.
here, we have,
We need to graph the log function. F(x) = log6x
Domain: x>0 All real number greater than 0.
Range: All real number.
y-intercept: Put x=0 and solve for y. (Does not exist)
y-intercept: Put y=0 and solve for x. (1,0)
Log function is increasing function.
F is true. (It is increasing)
D is False. (Because Range is all real number)
E is true. (x-intercept (1,0))
A is false. (It is decreasing.)
B is false. (The y-intercept is (0, 6))
C is false. (Domain is x>0)
Hence, F and E are true.

Which formula should be used to calculate the variance?.
Answer:
C is the formula you should use and the rest of the answers are below
Step-by-step explanation:
Hence, the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.
We have Variance.
We have to specify the formula of variance.
What is Variance?Variance is a measure of dispersion that takes into account the spread of all data points in a data set.
According to the question, the following formulae for variance are used according to the need.
For a Complete Population divide by the size n -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex]
For a Sample Population divide by the sample size minus 1
[tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex]
Hence, the the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.

In the figure below, line j is parallel to line k and line r is parallel to s. Which statement is FALSE?
d° = f°
a° + d° = 180°
a° = c°
b° + e° = 180°
The false statement:
a° + d° = 180°
The correct option is B.
What are the corresponding angles?Corresponding angles are those formed at matching or corresponding corners with the transversal when two parallel lines are crossed by another line (i.e. the transversal).
Given:
Two pairs of parallel lines j and k, and r and s traverse each other.
d° = f° {opposite angles}
a° + d° = 180°
This is an incorrect statement.
a° = c° {Corresponding angles}
b° + e° = 180° (Sum of linear pair)

Answer
Club = 7
Diamond = 6
Spade = 2
Heart = 5
Step-by-step explanation
Here it shows that 1 club + 1 diamond + 1 spade is equal to 15. Ok, let's get back to that one later.
In the next hint it shows that 3 clubs equals 21. So, in order to get the value of the club, divide 21 by 3, and you'll get 7. This means that 7 is the value of the club.
Now on to the third hint. Here it shows that 1 diamond plus 2 clubs are equal to 20. We already got the value of the club, which is 7, so add 7+7 and you'll get 14. Then, subtract 14 from 20 and you'll get the value of the diamond, which is 6.
Finally, the fourth hint. Here it shows that 1 diamond + 1 heart + 1 spade = 13. So, inorder to get the value of the heart, add the value of the diamond and the spade, which sums up to 8. Then subtract 8 from 13 and you'll get the value of the heart, which is 5.

Answer:
£59.25
Step-by-step explanation:
It appears you can measure the height of the trapezoid [trapezium :-) ??]. If you can't, you can use the Pythagorean Theorem (image attached). Draw a line from the upper right-hand corner down to the baseline--the 20m side. You'll form a right triangle with one leg h , hypotenuse 17m and the other leg 8m (the difference between 20m and 12m).
(leg)^2 + (leg)^2 = (hypotenuse)^2
h^2 + 8^2 = 17^2
h^2 + 64 = 289
h^2 = 225
h = 15m
The area of the trapezium is [tex]A=\frac{1}{2}h\left(b_1+b_2\right)[/tex] where the b's are the lengths of the two bases (upper and lower sides).
[tex]A=\frac{1}{2}(15)(12+20)=\frac{1}{2}(480) = 240[/tex] m^2
One can of weedkiller covers 100 m^2 of area. You'll need 3 cans (2 cans isn't enough, and you can't buy a fraction of a can). Tricky question!

rectangle is represented by
4a + 3b, and its width is
represented by 7a – 2b. Write
a polynomial for the perimeter
of the rectangle.
Solution:
Given:
Length of rectangle = 4a + 3bWidth of rectangle = 7a - 2bPerimeter of rectangle = 2W + 2LLet's simplify the perimeter of the rectangle by using the expression for the perimeter.
=> 2W + 2L=> 2(7a - 2b) + 2(4a + 3b)=> 14a - 4b + 8a + 6b=> 22a + 2bHence, the polynomial that represents the perimeter of the rectangle is 22a + 2b.

What fraction is equal to 75% of 1/3
Answer:
1/4
Step-by-step explanation:
1.) Take 75% and convert it to a decimal, which is 0.75
2.) Then multiply 1/3 by 0.75
3.) Your answer is 0.25, and when 0.25 is converted to a fraction it is 1/4.
75% of 1/3 can be expressed as the fraction 1/4 by convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction
To find the fraction that is equal to a given percentage of another fraction, follow these steps:
Step 1: Convert the percentage to a decimal by dividing it by 100. In this case, 75% is equivalent to 0.75.
Step 2: Multiply the decimal by the original fraction. In this case, 0.75 * 1/3 = 0.25/1.
Step 3: Simplify the resulting fraction, if possible. In this case, the fraction 0.25/1 can be simplified to 1/4.
Therefore, 75% of 1/3 is equal to the fraction 1/4.
To find the fraction that represents a given percentage of another fraction, convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction if necessary. In this case, 75% of 1/3 is equal to the fraction 1/4.
