Answer:
46.8
Step-by-step explanation:
The missing angle in ∆PQR is 180° -76° -41° = 63°. Two angles are the same between the triangles, so we know they are similar. Side lengths of similar triangles are proportional.
Corresponding sides of the triangles are ...
ST ⇔ PQ ratio ST/PQ = 16.8/14 = 1.2
TU ⇔ QR ratio TU/QR = x/10 = 1.2 ⇔ x = 12
US ⇔ RP ratio US/RP = 18/15 = 1.2
The perimeter of ∆STU is the sum of its side lengths ...
16.8 +12 +18 = 46.8 . . . units
_____
Additional comment
The perimeter of PQR is 14 +10 +15 = 39. The scale factor applies to the perimeter, just as it does to the side lengths.
The perimeter of STU is 1.2×39 = 46.8.

Which describes the graph of y = (x - 4)2 - 1?
-
A. Opens up with a vertex at (4,-1)
B. Opens down with a vertex at (4,-1)
C. Opens up with a vertex at (-4,-1)
D. Opens down with a vertex at (-4,-1)
C opens up with a vertex at (-4,-1)
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x - 4)² - 1 ← is in vertex form
with vertex = (h, k ) = (4, - 1 )
• If a > 0 then the graph opens up
• If a < 0 then the graph opens down
Here a = 1 > 0 then graph opens up
Thus option A

Answer:
like the book series? if so yes its great
Step-by-step explanation:
Select the two binomials that are factors of
81x2 - 36
0 9x - 6
9x + 12
9x + 6
9x - 3
Factors are 9x-6 and 9x+6
=================================================
Explanation:
We use the difference of squares rule
m^2 - n^2 = (m-n)(m+n)
In this case we have
m = 9xn = 6So,
m^2 - n^2 = (m-n)(m+n)
(9x)^2 - 6^2 = (9x-6)(9x+6)
81x^2 - 36 = (9x-6)(9x+6)
Answer:
9x + 6 and 9x -- 6
Step-by-step explanation:
81x2--36 = (9x) 2 -- (6)2 = a2 -- b2 = (a+ b )(a--b) = (9x+6)(9x-6)
Steve set up a business making friendship bracelets. He earned $70 in January. He is projected to earn 120% more in February. How much is Steve projected to make in February? PLS HELP!
$84
$98
$154
$190
Answer:
its 84 dollars sorry I'm late
Step-by-step explanation: Make a proportional relationship.
make 120% into a fraction. 120/100
then make 70 into a fraction using a variable. For example, x/70
Then cross multiply 120 and 70. 120x70=8,400
Last divide 8,400 by 100 and that equals $84.
Hope this helps!
Can someone please help me?
The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
Part B
How many feet apart are the two ocean elevations described in part A?
Part C
What is the elevation of the deck where Winston ate dinner?
Part D
What is the elevation of the surf shop?
Part F
What was the distance between the surf shop and the ocean’s surface at 7 p.m.? Which was higher, the surf shop or the ocean?

two numbers that multiplied together give me 10 and the difference of the two numbers is -2?
Answer:
10/(1+√11), 1+√11 and 10/(1-√11) and 1-√11
Step-by-step explanation:
Let x be the first number and y the second number
two numbers that multiplied together give me 10
x*y = 10
and the difference of the two numbers is -2?
x-y = -2
we can write x in terms of y so we only have one variable y
x-y =-2 , add y to both sides
x-y+y = y -2, combine like terms
x= y-2
x*y = 10, substitute x=y-2
(y-2)y = 10, distribute in parenthesis
y² -2y-10 = 0, subtract 10 from both sides
We can use the quadratic formula to solve y² -2y-10 = 0
y = (-b±√b²-4ac)/2a, where a= 1, b= -2, c= -10
y = (2±√4+4*1*10)/2
y = (2±√44)/2
y= (2±2√11)/2
y= 1±√11
x*y = 10, divide both sides by y
x= 10/y
x= 10/(1±√11)
Check :
x*y = 10
[10/(1±√11)] * (1±√11) = 10
⇒[10/(1+√11)] * (1+√11) = 10✅
⇒[10/(1-√11)] * (1-√11) = 10✅
⇒[10/(1+√11)] * (1-√11) = 10❌
⇒[10/(1-√11)] * (1+√11) = 10❌
x-y = -2
⇒
[10/(1+√11) ] -(1+√11) =
[10 -(1+√11 )(1+√11 )]/ (1+√11 ) =
[10 - (1+11+2√11)]/ (1+√11) =
(10-12 -2√11) / (1+√11) =
(-2 -2√11) / (1+√11) =
-2(1+√11)/ (1+√11) =
-2 ✅
⇒
[10/(1-√11) ] -(1-√11) =
[10 -(1-√11 )(1-√11 )]/ (1-√11 ) =
[10 - (1+11-2√11)]/ (1-√11) =
(10-12 +2√11) / (1-√11) =
(-2 +2√11) / (1-√11) =
-2(1 -√11)/ (1-√11) =
-2 ✅
Write a fraction setting the vertical length of the smaller triangle and the bigger triangle over its horizontal length. What do these fraction represent?
To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true? Why or why not? What does that mean about the slope between points E and A and the slope between the points A and C?
Step-by-step explanation:
Vertical length of the smaller triangle is:
2 - 0 = 2Horizontal length of the smaller triangle is:
3 - 0 = 3The fraction:
2/3This fraction is same for the larger triangle, which is 4/6 = 2/3.
It means the slopes are same.
Since the slopes are same, the segments are part of same red line.
Enter a digit in each box to complete the addition problem.
What is an equation of the line that passes through the points (-3, -1) and (6, 2)
Answer:
y = 1/3x
Step-by-step explanation:
Using the slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
Taking (-3,-1) as (x1,y1) and (6,2) as (x2,y2):
(2-(-1))/(6-(-3))
= (2+1)/(6+3)
= 3/9
= 1/3
Hence, the slope (m) is 1/3
Substituting the slope into 'y = mx+c':
y = 1/3x + c
Substituting any point, however, we will be substituting (-3,-1):
-1 = 1/3 * (-3) + c
-1 = -1 + c
c = -1 + 1
= 0
Hence,
y = 1/3x

Estimate 11.92 x 3.21
11.92 × 3.21 = 38.2632
Answer:
-If you need to round to the whole number, you would round down to 38
-If your answer needs to be a decimal, it would be 38.30
If you don't have a specific way you need to round it, estimates are usually whole numbers, so your answer would be 38
