Answer:
The distance of QR is 54 units
Step-by-step explanation:
In the isosceles triangle, The height drawn from the vertex angle to the base bisects the base
In ΔPQR
∵ PQ = PR
∴ Δ PQR is an isosceles triangle
∵ P is the vertex angle
∵ QR is the base
∵ PS ⊥ QR
→ By using the fact above
∴ PS bisects QR
∴ S is the midpoint of QR
→ That means S divided QR into 2 equal parts QS and SR
∵ QS = SR
∵ QS = 6n + 3
∵ SR = 4n + 11
→ Equate them to find n
∴ 6n + 3 = 4n + 11
→ Subtract 4 n from both sides
∵ 6n - 4n + 3 = 4n - 4n + 11
∴ 2n + 3 = 11
→ Subtract 3 from both sides
∵ 2n + 3 - 3 = 11 - 3
∴ 2n = 8
→ Divide both sides by 2
∴ n = 4
→ Find the length of QS by substitute x in its expression by 4
∵ QS = 6(4) + 3 = 24 + 3
∴ QS = 27
∵ QS = SR
∴ SR = 27
∵ QR = QS + SR
∴ QR = 27 + 27
∴ QR = 54 units
∴ The distance of QR is 54 units

Answer:
a. 2/5
b. 1/2
c. 100/9
Step-by-step explanation:
a: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:
.12 × 100 = 12
.3 × 100 = 30
Simplify: 12/30 = 2/5
b: Multiply bottom and top by 1,000 to keep values the same and make the fraction a whole fraction:
.125 × 1,000 = 125
.25 × 1,000 = 250
Simplify: 125/250 = 1/2
c: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:
4 × 100 = 400
.36 × 100 = 36
Simplify: 400/36 = 100/9
Patti got a new part-time job. Her hourly wage increased from $10.50 to $12.39. What was the percent increase in Patti's hourly wage?
Answer:
18%
Step-by-step explanation:
Subtract $10.50 from $12.30 and you will get 1.8.
Then divide 1.8 to 100 (because 100% = total) and you will get 0.018 which means 18%. Her hourly wage increased by 18%.
please answer this. thank you
Answer: [tex](-\infty, -4][/tex]
Curved parenthesis at negative infinity
Square bracket at -4
====================================================
Work Shown:
[tex]5(x+4) \le 0 \\\\x+4 \le \frac{0}{5} \\\\x+4 \le 0 \\\\x \le 0-4 \\\\x \le -4 \\\\[/tex]
The last inequality shown above is the same as saying [tex]-\infty < x \le -4[/tex]
Converting this to interval notation leads to the final answer of [tex](-\infty , -4][/tex]
Note the use of a square bracket at -4 to include this endpoint. We can never include either infinity, so we always use a parenthesis for either infinity.

2. Find the slope of the line graphed below.
pleases show workkkkkkkkkkkkkkkk
Answer:
5) 2(4 - n) = -3n
2 × 4 - 2 × n = -3n
8 - 2n = -3n
-2n + 3n = -8
1n = -8
n = -8/1
n = -8
6) 5 - 3(2 + 2w) = -7
5 - 3 × 2 + -3 × 2w = -7
5 - 6 - 6w = -7
-1 - 6w = -7
-6w = -7 + 1
-6w = -6
w = -6/-6
w = 1
7) 5(2r + 3) - 5 = 0
5 × 2r + 5 × 3 - 5 = 0
10r + 15 - 5 = 0
10r + 10 = 0
10r = -10
r = -10/10
r = -1
8) 3 - 5(2d - 3) = 4
3 - 5 × 2d - 5 × -3 = 4
3 - 10d + 15 = 4
-10d + 15 + 3 = 4
-10d + 18 = 4
-10d = 4 - 18
-10d = -14
d = -14/-10
d = 7/5
hope this helps you!!

The isosceles triangle has two sides with the same length. The base is one-half the length of a side. The expression which represents the perimeter, the distance around the triangle, is s + s + one-half s. What is the value of this expression if s = 8?
A triangle with 2 sides with length s.
Answer:
20 units
Step-by-step explanation:
s = 8
Perimeter = s + s + [tex]\frac{1}{2}*s[/tex]
[tex]= 8 + 8 + \frac{1}{2}*8[/tex]
= 8 + 8 + 4
= 20 units

Answer:
There will be 416 students in each group.
Step-by-step explanation:
There are 1,248 students. There are also 3 groups: radical readers, mathematicians, and super scientists. To find the number of people in each group, divide the total students by the number groups, which would be 1,248 divided by 3.
Is the inequality true or false when t = -3: 33/t - 2 ≥ -8
Math Problem: Convert
Answer:
135°
Step-by-step explanation:
To convert from radians to degrees
degree = radian × [tex]\frac{180}{\pi }[/tex]
Thus for [tex]\frac{3\pi }{4}[/tex]
degree = [tex]\frac{3\pi }{4}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel the π )
= [tex]\frac{3(180)}{4}[/tex]
= [tex]\frac{540}{4}[/tex]
= 135°
can someone check these and tell me which ones are in the wrong column, thanks
Answer:
∠2 and ∠5 should not be Alternate exterior angles. ∠2 and ∠11 can be Alternate exterior angles if that is an option. The rest is correct. As for consecutive interior angles, you have (∠3 and ∠9), (∠4 and ∠10), (∠7 and ∠13) and (∠8 and ∠14).
Step-by-step explanation:
Alternate exterior angles are basically like the angles that are the combination of a vertically opposite angle and a corresponding angle. Since the vertical lines are not parallel, ∠2 and ∠5 cannot be Alternate exterior angles.
Consecutive interior angles are any pair of angles that are within a pair of parallel lines and add up to 180°.
What is the remainder when
f(x) = 2x4 + x2 – 8x – 1 is divided
by x - 6?
Answer:
Step-by-step explanation:
x - 6 = 0
x = 6
f(x) = 2x⁴ + x² - 8x - 1
=2(6)⁴+ 6² - 8*6 - 1
= 2*1296 + 36 - 48 - 1
= 2592 + 36 - 48 - 1
= 2628 - 49
= 2579

Which statement best describes parallel lines?
Parallel lines intersect at exactly one point.
Parallel lines intersect at exactly one point. ,
Parallel lines intersect infinitely many times.
Parallel lines intersect infinitely many times. ,
Parallel lines have equal slopes.
Parallel lines have equal slopes. ,
Parallel lines have negative reciprocal slopes.
Answer:
Step-by-step explanation:
Parallel lines have identical slopes and different y intercepts.
y = 3x + 2
y = 3x + 9
These lines are parallel with the same slopes (3) and different y intercepts (2 and 9)
Write an equation of the line that passes through (-2, 3) and is parallel to the line y= 2x-4
Answer:
A hi esta la solucion
Step-by-step explanation:
Answer:
y=2x+7
Step-by-step explanation:
Since the answer HAS to be parallel to the line y=2x-4, that means the only number that should change is the y-intercept (the last number in the equation.) y-intercept is the x-value when y=0, which basically means, if you put the line onto a graph, look for the point when the line passes through the y-axis, then look at how far up or down that point is (x-value). That will be your answer. Since the line passes through the y-axis at x=7, the answer is y=2x+7! Sorry if this is too confusing, I'm not good at teaching XD
