Select all the statements about the figure that MUST be true. Р Q 6n + 3 S 4n + 11 R PR=15 QS=21 QP=13 n=7 SR=27 QR=54
Answer:
Options (5) and (6)
Step-by-step explanation:
From the picture attached,
In right triangle ΔPSQ and ΔPSR,
PS ≅ PS [By reflexive property]
PQ ≅ PR [Given]
ΔPSQ ≅ ΔPSR [By HL property of congruence]
Therefore, QS ≅ SR [CPCTC]
(6n + 3) = (4n + 11)
6n - 4n = 11 - 3
2n = 8
n = 4
QS = (6n + 3)
= 6×4 + 3
= 27
SR = (4n + 11)
= 4×4 + 11
= 16 + 11
= 27
QR = QS + SR
= 27 + 27
= 54
Therefore, Options (5) and (6) are the correct options.
(3x-4)(x+7)-1/4x^2 as a trinomial in standard form. If you can pls provided step by step explanation
The trinomial in standard form is 11/4x² + 17x - 28
How to rewrite the expression?The expression is given as:
(3x-4)(x+7)-1/4x^2
Rewrite properly as:
(3x - 4)(x + 7) - 1/4x²
Expand the expression
3x² - 4x + 21x - 28 - 1/4x²
Collect like terms
- 1/4x² + 3x² - 4x + 21x - 28
Evaluate the like terms
11/4x² + 17x - 28
Hence, the trinomial in standard form is 11/4x² + 17x - 28

At the time that a 55 foot tall tree casts a shadow that is 32 feet long, a nearby woman is 5.5 feet tall. Which measure is the closest to the length of the shadow she will cast?
Answer:
3.2ft long shadow
Step-by-step explanation:
In this problem we are given a ratio between the tree/shadow and woman/shadow therefore we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the length of the shadow which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
55ft tall <======> 32ft long shadow
5.5ft tall <======> x ft long shadow
(5.5 * 32) / 55 = 3.2ft long shadow
Finally, we can see that the woman's shadow would be a 3.2ft long shadow

20 POINTS An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. The total cost of the electrician's services can be determined using the equation C=65+60t, where t is the number of hours the electrician spends at the house working. What is the slope of the equation and what is its interpretation in the context of the problem?
Answer:
[tex]the \: slope \: is \to \boxed{60}[/tex]
Step-by-step explanation:
[tex]if \to C=65+60t \\ C=60t + 65 \\ but \: the \: \boxed{ c - intercept} \: is \: in \: the \: form \to \\ c = mt + b \\ hence \to \\ 60t = mt \\ m = \frac{60t}{t} \\ m = 60 \\ the \: slope \: is \to \boxed{60}[/tex]
We want to analyze the given linear equation, we will find that the slope is 60, and it means that he charges 60 per hour.
Linear equations:
A general linear equation is written as:
y = a*x +b
Where a is the slope and b is the y-intercept.
In this case, we have the equation:
c(t) = 60*t + 65
Is easy to identify that the slope is equal to 60.
Given that we know that he charges per hour, and that t represents the number of hours that the electrician worked, we can assume that the slope represents how much the electrician charges per hour.

Is y=1/2x-1 proportional
Answer: No
Step-by-step explanation: Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.
The temperature at 2 am was -12 degrees. At noon the temperature had risen 16 degrees. At 4 pm the temp dropped 8 degrees. What was the temperature at 4 pm
Answer: - 4
because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees
=> the temperature at noon was -12 + 16 = 4 (degrees)
At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:
4 - 8 = -4 (degrees)

help!!! I'm not really good at graphs so I also need an explanation please!
Answer:
Hi, I think it's DEGF
Step-by-step explanation:
for y=x－2,
just move y=x down 2 units.
for x=－2,
it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.
for－2x+4,
you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.
for x²-4,
see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.
Hope this will help u!!
∠A is complementary to ∠B. The measure of ∠A is (8x+12)∘. The measure of ∠B is half the measure of ∠A.
Write an equation that can be used to determine the value of x. Then solve for x.
The equation that can be used to solve for x is 8x + 12 + 4x + 6 = 90.
The value of x is 6.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
∠A and ∠B are complementary.
This means,
∠A + ∠B = 90
Now,
∠A = 8x + 12
∠B = (8x + 12)/2 = 4x + 6
Now,
8x + 12 + 4x + 6 = 90
12x + 18 = 90
12x = 90 - 18
12x = 72
x = 72/12
x = 6
Thus,
The value of x is 6.
