Answer:
the answer is 65
Step-by-step explanation:
2x+7/27 = 4x + 1/45
45(2x + 7) = 27(4x + 1)
90x + 315 = 108x + 27
108x-90x = 315-27
18x = 288
x = 288/18
x = 16
BK = 4x + 1
BK = 4(16) + 1
BK = 64 + 1
BK = 65
The value of the variable 'x' is 8/7. Then the length of the side BK will be 5.57 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangle ΔNQZ is similar to the triangle ΔCBK. Then the ratio of the corresponding side will remain constant. Then the equation is given as,
BK / QZ = KF / TZ
(2x + 7) / (4x + 1) = 45 / 27
(2x + 7) / (4x + 1) = 5/3
Simplify the equation, then we have
(2x + 7) / (4x + 1) = 5/3
6x + 21 = 20x + 5
14x = 16
x = 8/7
The length of the side BK is calculated as,
BK = 4x + 1
BK = 4(8/7) + 1
BK = 32/7 + 1
BK = 39/7
BK = 5.57 units
The value of the variable 'x' is 8/7. Then the length of the side BK will be 5.57 units.

Write a question that represents the following equation: 22 − n = 15 .
Answer:
Maya had 22 cookies she gave out 7 to her classmates, how many does she have now?
The value of equation 22 − n = 15 is 7.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Equation: 22 − n = 15
Now, Subtract 22 from both side
22 - n - 22 = 15 - 22
-n = -7
Now, multiply both side by (-1)
n= 7
Hence, the value of n is 7.

A certain form of cancer is known to be found in women over 60 with probability of 0.07. A blood test exists for the detection of the disease, but the test is not infallible. In fact, it is known that 10% of the time the test gives a false negative (i.e. the test incorrectly gives negative result when the woman actually has the cancer) and 5% of the time the test gives false positive (i.e. incorrectly gives a positive result when the woman actually does not have the cancer). What is the probability that a randomly selected woman over 60 will test positive?
Answer:
Throughout the segment below, the definition including its particular question is mentioned.
Step-by-step explanation:
The probability of developing cancer
= 0.07
The probability of someone not getting cancer
= 1 - 0.07
= 0.93
Provided that if women have cancer, the risk of someone not testing positive is:
= 0.10
Therefore, if a female requires cancer, the risk of testing positive
= 1 - 0.10
= 0.90
The Probability of positive test
= 0.055 (whenever a woman does not have cancer)
Therefore, whenever a woman does not have cancer, the risk of not testing positive will be:
= 1 - 0.05
= 0.955
Now,
By using the law of conditional probability, we get
⇒ [tex]P(\frac{B}{A} ) = \frac{P(A \ and \ B)}{P(A)}[/tex]
⇒ [tex]P (A \ and \ B) = P(A)\times P(B)[/tex]
⇒ P (having cancer as well as positive tests) = P(having cancer) × P(Effective results, because she has cancer)
⇒ [tex]0.07\times 0.90[/tex]
⇒ [tex]0.063[/tex]
Correspondingly,
P (not getting cancer and testing effective or positive)
= [tex]0.93\times 0.05[/tex]
= [tex]0.04655[/tex]
P (with a good test result)
= [tex]0.063 + 0.0465[/tex]
= [tex]0.1095[/tex]

Let F(x)=-7x-12 and g(x)=13-3x. What is f-g?
Answer:
[tex] (f - g)x = -4x - 25 [/tex]
Step-by-step explanation:
Given:
[tex] f(x) = -7x - 12 [/tex]
[tex] g(x) = 13 - 3x [/tex]
Required:
[tex] (f - g)x [/tex]
SOLUTION:
[tex] (f - g)x = f(x) - g(x) [/tex]
[tex] f(x) - g(x) = (-7x - 12) - (13 - 3x) [/tex]
[tex] = -7x - 12 - 13 + 3x [/tex]

If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f + g)(x).
Answer:
(f+g)(x) = [tex]3x^{2} - 6[/tex]
Step-by-step explanation:
First, lets understand what (f+g)(x) means.
(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).
So, this is what the equation looks like when you substitute the functions in to (f+g)(x):
(f+g)(x) = [tex](2x^{2} +1) + (x^{2} -7)[/tex]
Now, combine like terms and Simplify:
(f+g)(x) = [tex]3x^{2} - 6[/tex]

What is 35 million in scientific notation
find the slope, vertical intercept and horizontal intercept of (2,9) and (4,3)
Answer:
M = - 3
Step-by-step explanation:
Find the Slope:
Slope is equal to the change in y over the change in x
, or rise over run.
m = [tex]\frac{change in Y}{change in X}[/tex]
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Substitute in the values of x and y into the equation to find the slope.
m = [tex]\frac{3-(9)}{4-(2)}[/tex]
Simplify.
m = [tex]\frac{-6}{2}[/tex]
m = -3

Let a, b, and c be integers. Consider the following conditional statement:
If a divides bc, then a divides b or a divides c
Which of the following statements have the same meaning as this conditional statement, which ones are the negations, and which ones are not neither? Justify your answers using logical equivalences or truth tables.
A) If a does not divide b or a does not divide c, then a does not divide bc.
B) If a does not divide b and a does not divide c, then a does not divide bc.
C) If a divides bc and a does not divide c, then a divides b.
D) If a divides bc or a does not divide b, then a divides c. (e) a divides bc, a does not divide b, and a does not divide c.
Step-by-step explanation:
Given that the logical statement is
"If a divides bc, then a divides b or a divides c"
we can see that a must divide one either b or c from the statement above
A) If a does not divide b or a does not divide c, then a does not divide bc.
This is False because a can divide b or c
B) If a does not divide b and a does not divide c, then a does not divide bc.
this is True for a to divide bc it must divide b or c (either b or c)
C) If a divides bc and a does not divide c, then a divides b.
This is True since a can divide bc and it cannot divide c, it must definitely divide b
D) If a divides bc or a does not divide b, then a divides c.
This is True since a can divide bc and it cannot divide b, it must definitely divide c
E) a divides bc, a does not divide b, and a does not divide c.
This is False for a to divide bc it must divide one of b or c
