Answer:
the correct choice is marked
Step-by-step explanation:
The lengths will form a right triangle if the squares of the two shortest legs total the square of the longest. The square of a root is the number under the radical, so you're looking to see if the two smallest numbers under the radicals total the largest number under the radical.
A: 22 +88 = 110 . . . . . a right triangle
B: 66 +99 = 165 ≠ 176 . . . . an obtuse triangle
C: 22 +110 = 132 ≠ 121 . . . . an acute triangle
D: 66 +77 = 143 ≠ 154 . . . . an obtuse triangle
_____
Additional comment
The largest angle is opposite the longest side. If the longest side is too long for the triangle to be a right triangle, then the opposite angle is larger than 90°, and the triangle is obtuse. If the longest side is too short for a right triangle, then the triangle is acute.

Answer:
6300 kg is equivalent to 6.3·10^5 g
Step-by-step explanation:
Convert 6300 kg TO g in standard form. Recall that 1000 g = 1 kg.
1000 g
Multiplying 6300 kg by ------------- results in 63·10^4, or 6.3·10^5
1 kg
6300 kg is equivalent to 6.3·10^5 g.

Solve (x-4)^2=5
answer: (x=5+√4
Answer:
x = 4 + sqrt 5
x = 4 - sqrt 5
Step-by-step explanation:
(X-4)^2 = 5
X - 4 = + - sqrt 5
X = 4 + sqrt 5 and
X = 4 - sqrt 5
Answer:
Step-by-step explanation:
Take the square root of each side of the equation to set up the solution for x
[tex](x-4)^{2*\frac{1}{2} } =[/tex] ±[tex]\sqrt{5}[/tex]
Remove the perfect root factor x - 4 under the radical to solve for x.
x - 4 = ±[tex]\sqrt{5}[/tex]
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
[tex]x-4=\sqrt{5}[/tex]
Add 4 to both sides of the equation.
[tex]x=\sqrt{5} +4[/tex]
Next, use the negative value of the ± to find the second solution.
[tex]x-4=-\sqrt{5}[/tex]
Add 4 to both sides of the equation.
[tex]x=-\sqrt{5} +4[/tex]
The complete solution is the result of both the positive and negative portions of the solution.
[tex]x=\sqrt{5} +4,-\sqrt{5} +4[/tex]

Jack is paid £2400 a month.
He spends half his money on rent,
He spends the rest on food, bills and savings in the ratio 3:5:4
How much does he spend on bills?
(I really need help with this) - TYSM if anyone is able to help) :)
Answer:
300+400+500=1200
Step-by-step explanation:
given total paid $2400
spend $1200 on a rent (half of his paid)
so rest he spend as a ratio of 3:4:5=1200
let x as a amount he using to pays rest of the bills so
3x+4x+5x=1200
12x=1200
x=1200/12
x=100
so he spends 3x=300
4x=400
5x=500

Write an equation of the line that passes through (6, 1) and is perpendicular to x +2y-12=0.
Answer:
y = 2x - 11
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes—multiplying the slopes of two lines results in a product of -1.
Given the linear equation, x + 2y - 12 = 0, and the other point, (6, 1):
Convert the given linear equation into its slope-intercept form:
x + 2y - 12 = 0
Subtract x from both sides:
x - x + 2y - 12 = - x 0
2y - 12 = -x
Next, add 12 to both sides of the equation:
2y - 12 + 12 = -x + 12
2y = -x + 12
Divide both sides by 2 in order to isolate y:
y = - ½x + 6
Since the slope of the given equation is - ½, then the other line perpendicular to it must have a slope of 2:
Let m₁ = - ½
m₂ = 2
m₁ × m₂ = -1
-½ × 2 = -1
Hence, the slope of the other line, m₂ = 2. Next, using the slope of the other line, m₂ = 2, and the other given point, (6, 1), substitute these values into the slope-intercept form to solve for the y-intercept, (b):
y = mx + b
1 = 2(6) + b
1 = 12 + b
1 - 12 = 12 - 12 + b
-11 = b
Thus, the y-intercept of the other line is b = -11.
Therefore, the linear equation of the line that is perpendicular to x + 2y - 12 = 0 is:
y = 2x - 11.As a proof, attached is the graph of both equations, where it shows that they are perpendicular from each other.

Step-by-step explanation:
I grew up on a pig farm. We raised baby pink pigs from birth to 8 weeks old. A 90% confidence interval is calculated for a sample of weights of 135 randomly selected 8-week old pigs. The resulting confidence interval is 75 to 90 pounds. Will the sample mean weight, from this random sample of 135 pigs, fall within the confidence interval?
a. yes
b. no
c. maybe
Answer:
A
Step-by-step explanation:
3 4 5 6
The sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)
How to find the confidence interval for large samples (sample size > 30)?Suppose that we have:
Sample size n > 30Sample mean = [tex]\overline{x}[/tex]Sample standard deviation = [tex]s[/tex]Population standard deviation = [tex]\sigma[/tex]Level of significance = [tex]\alpha[/tex]Then the confidence interval is obtained as
Case 1: Population standard deviation is known[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{\sigma}{\sqrt{n}}[/tex]
Case 2: Population standard deviation is unknown.[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}}[/tex]
For this case, we work with sample standard deviation(you can choose even population standard deviation, it won't matter as both are not given here).
We're provided that:
Sample size = n = 135Confidence interval is of 90%, therefore, Level of significance = [tex]\alpha[/tex] = 100 - 90% = 10% = 10/100 = 0.1 (converted percent to decimal)The critical value of Z at 0.1 level of significance is [tex]\pm 1.645[/tex]Confidence interval's limits = 75 (lower limit) and 90(upper limit) (in pounds)Sample mean = [tex]\overline{x}[/tex]Sample standard deviation = [tex]s[/tex]Since the formula for limits of confidence interval is:
[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}} = \overline{x} \pm 1.645\dfrac{s}{\sqrt{135}}[/tex]
That has:
[tex]\text{Lower limit} = 75 = \overline{x} - 1.645\dfrac{s}{\sqrt{135}}\\\\\text{Upper limit} = 90 = \overline{x} +1.645\dfrac{s}{\sqrt{135}}\\\\[/tex]
Thus, we get:
Adding both the equations, we get:
[tex]165 = 2\overline{x}\\\\\overline{x} = 82.5 \: \rm pounds[/tex]
That is between 75 and 90 pounds.
Thus, the sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)

Answer:
8 + (-3) = 5
Step-by-step explanation:
A number line offers a suitable model. +8 is represented by a segment extending from 0 to 8. -3 is represented by a segment extending from 0 to -3. The addition of those numbers is modeled by placing those segments end-to-end. In the attachment, we have shown -3 placed so it starts at the end of +8. The other end of -3 lies at the sum: 5.
8 + (-3) = 5
