solve for x x^2 + 10x + 25 = 27
[tex]~~x^2+10x+25 = 27\\\\\implies x^2+2\cdot 5 x +5^2 = 27\\\\\implies (x+5)^2 = 27\\\\\implies x +5 = \pm\sqrt{27}\\\\\implies x = -5 \pm\sqrt{3\times 9}\\\\\implies x = -5 \pm3\sqrt 3\\\\\text{Hence,}~~ x = -5 + 3 \sqrt 3 ,~~~ x =-5-3\sqrt3[/tex]
Three students, Alicia, Benjamin, and Caleb, are constructing a square inscribed in a circle with center at point C.
Alicia draws two diameters and connects the points where the diameters intersect the circle, in order, around the circle.
Benjamin tells Alicia that she was not being very accurate. He says that the diameters must be perpendicular to each other. Then she can connect the points, in order, around the circle.
Caleb tells Alicia and Benjamin that he doesn’t need to draw the second diameter. He says that because a triangle inscribed in a semicircle is a right triangle, he will simply draw two such triangles, one in each semicircle. Together the two triangles will make a square.
Who is correct?
Only Alicia is correct.
Only Benjamin is correct.
Only Caleb and Benjamin are correct.

Answer:
5.946
Step-by-step explanation:
The pythogorean theorem states that a^2+b^2=c^2.
We are given the hypotenuse, c, and a side length.
3.5^2+b^2=6.9^2
12.25+b^2=47.61
b^2=35.36
b=5.9464...., rounded to 5.946
Write a recursive formula for a n a n , the n th n th term of the sequence 6 , − 12 , 24 , . . .
Answer:
See below ↓↓
Step-by-step explanation:
a₁ refers to the first term of the sequence.
That is clearly : a₁ = 6
The formula for the nth term is :
aₙ = a₁rⁿ⁻¹Common ratio (r) = quotient of consecutive termsr = -12/6 = -2Therefore, the nth term is :
aₙ = 6(-2)ⁿ⁻¹One sample has ss = 60 and a second sample has ss = 48.
if n = 7 for both samples, find each of the sample variances, and calculate the pooled variance. because the samples are the same size, you should find that the pooled variance is exactly halfway between the two sample variances
The pooled variance of the samples estimates the weighted variance of the samples
The pooled variance is 2952
How to calculate the pooled variance?The given parameters are:
Sample 1:n = 7
ss = 60
Sample 2:n = 7
ss = 48
The pooled variance is calculated using:
Sp = [SS1^2 *(n1 - 1) + SS2^2 *(n2 - 1)]/[(n1 - 1) + (n2 - 1)]
So, we have:
Sp = [60^2 *(7 - 1) + 48^2 *(7 - 1)]/[(7 - 1) + (7 - 1)]
Evaluate the expression
Sp = 2952
Hence, the pooled variance is 2952

The infusion time for the IV solution that was prescribed = 128 mins.
Calculation of IV infusion timeTo calculate the infusion time the formula for IV drip rate is used which is;
Drip rate = volume/time × Drop factor
Drip rate = 25gtt/min
Volume = 320mL
Drop factor= 10 gtt/mL
Time = ?
From the formula above, make time the subject of formula. That is,
Time = vol × drop factor/drip rate
= 320 × 10/25
= 3200/25
= 128 mins
Therefore, the infusion time for the IV solution that was prescribed = 128 mins

If 20% of a number is 8, find 10% of that number.
Answer:
20%=8
10%=?
by cross multiplications,
10×8=80
80÷20=4
Hence the answer is 4.
Answer:
4
Step-by-step explanation:
think about it we have 8 and 20 %, multiply 8 by 5 since theres 20 % and its 20 % of 100. 100 / 20 = 5 * 8 = 40 but since we have 20 and 10 % getting compared we obv know that it would be half what the answer for 20 % of would be so 4 :D

A car traveled 1010 miles at an average speed of 3030 miles per hour
and then traveled the next 1010 miles at an average speed of 5050 miles
per hour. What was the average speed, in miles per hour, of the car for the
2020 miles?
The average speed, in miles per hour, of the car for the 20 miles is 37.5 mph
Average speedAverage speed v = d/t where
d = total distance and t = total timeMaking t subject of the formula, we have
t = d/v
Time to cover first 10 milesNow when the car travels 10 miles at an average speed of 30 miles per hour,
d = 10 mi and v = 30 mph.So, t = d/v
= 10/30
= 1/3 h
Time to cover next 10 miles
Also, when the car travels the next 10 miles at an average speed of 50 miles per hour,
d' = 10 mi and v' = 50 mph.So, t' = d'/v'
= 10/50
= 1/5 h
Time to cover 20 miles
The total time for the 20 miles is T = t + t'
= 1/3 h + 1/5 h
= (5 + 3)/15 h
= 8/15 h
Average speed for 20 miles
So, the average speed for the 20 miles is v = D/T where
D = 20 miles and T = 8/15 h.So, v = D/T
v = 20 mi ÷ 8/15 h
v = 20 × 15 mi/8 h
v = 2.5 × 15 mi/h
v = 37.5 mph
So, the average speed, in miles per hour, of the car for the 20 miles is 37.5 mph

Answer: 48/44
Step-by-step explanation: if the area is 144 the perimeter is going to be 48. if the area is 121 the perimeter is 44. to find the perimeter you have to find the sides, since it is a square they will all be the same length. you have to find the square of the area since the formula for it is lw. then once you find the length of each side, you multiply it by 4 to find the perimeter. then to find the other question multiply the permimeter by 5.

Answer:
Out of the two sums, B is the closest to the value to 1/2.
Steps for A:
Change 1/3 to 5/15
2+5/15
= 7/15
7/15 as a decimal: 0.46
0.50 - 0.46 = 0.04
Steps for B:
Change 6/7 to 18/21
Change 1/3 to 7/21
18-7/21
= 11/21
11/21 as a decimal: 0.52
0.52 - 0.50 = 0.02
