Liam wants to buy a lead for his guitar.
It must be longer than 7.59 m.
Lead Type Length
Lead A
7.5 m
Lead B
7.8 m
Lead C
8.3 m
Lead D
0.75 m
Answer:
B: 7.8m
Step-by-step explanation:
7.8m is 21cm more than 7.59m so it is close.
8.3 meters would be a bit too long for his lead.
In Yakuna it was -13 degrees in the morning. The highest tempature was 29. Was was the total number the temp. increased
Answer:
42 degrees
Step-by-step explanation:
Use a number line.
-13 - 13 = 0.
Now, we are at the base, 0. Then, add 29.
13 + 29 + 42.
The answer is 42. Hope it helps!
Find the inverse of f(x)=6x^5-11
Answer:
[tex]f^{-1}(x)=\sqrt[5]{\frac{x+11}{6}}[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=6x^5-11[/tex]
To find the inverse of a function, switch f(x) and x, change f(x) to f⁻¹(x), and solve for f⁻¹(x). So:
[tex]f(x)=6x^5-11\\x=6(f^{-1}(x))^5-11[/tex]
Add 11 to both sides:
[tex]x+11=6(f^{-1}(x))^5[/tex]
Divide both sides by 6:
[tex]\frac{x+11}{6}=f^{-1}(x)^5[/tex]
Take the fifth root of each side:
[tex]f^{-1}(x)=\sqrt[5]{\frac{x+11}{6}}[/tex]
And we're done :)
Answer:
[tex]f^-^1(x)=\sqrt[5]{\frac{x+11}{6} }[/tex]Step-by-step explanation:
[tex]f(x)=6x^5-11\\[/tex]
Let y equal the equation
[tex]y =6x^5-11\\y+11=6x^5\\\\Divide\:both\:sides\:of\:the\:equation\:by \: 6\\\frac{y+11}{6} = \frac{6x^5}{6} \\\\\frac{y+11}{6} = x^5\\ \\Quatric\:root\:both\:sides\\\sqrt[5]{\frac{y+11}{6} } = \sqrt[5]{x^5} \\\\\sqrt[5]{\frac{y+11}{6} } = x\\\\f^-^1(x) = \sqrt[5]{\frac{x+11}{6} }[/tex]

9/8m - 1/6m = -4 - 11/3
Answer:
m=-8
Step-by-step explanation:
im assuming the equation is: [tex]\frac{9}{8} m-\frac{1}{6} m=-4-\frac{11}{3}[/tex]
find common denominators i choose 24
9/8 = 27/24
1/6 = 4/24
11/3 = 88/24
4 = 96/24
now start solving:
(Note that because denominators are the same you can just ignore them and focus on the numerator)
simplify (27/24)m - (4/24)m to (23/24)m
simplify -(96/24) - (88/24) to -184/24
now you are left with 23/24 m = -184/24
get rid of denominators 23m=-184
Divide -184 by 23 to get m= -8
Sea level is defined as being at an elevation of O feet. The elevation of land is defined to be its height above or below sea level. The table shows the lowest elevations
in some states. Write the values in order from greatest to least.
Answer:
2,844 ft, 713 ft, 481 ft, 55ft.
Step-by-step explanation:
New Mexico has the highest of the lowest land elevations of the given states, at 2,844 feet. It is followed by Idaho, at 713 feet, which is followed by Nevada, at 481 feet. Arkansas has the lowest land elevation at 55 feet. The elevations in order from highest to lowest are thus 2,844 feet, 713 feet, 481 feet, and 55 feet.

Find an equation of the line that is perpendicular to 2x-3y=3 that passes through the point (1,2)
Answer:
The answer is
[tex]3x + 2y = 7[/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the perpendicular line we must first find the slope of the original line
From the question the original line is
2x - 3y = 3
Write the equation in the general form above
That's
3y = 2x - 3
y = 2/3x - 1
Comparing with the general equation above
Slope = 2/3
Since the lines are perpendicular to each other the slope of the perpendicular line is the negative inverse of the original line
Slope of perpendicular line = - 3/2
So the Equation of the line using point
( 1 , 2) and slope - 3/2 is
[tex]y -2 = - \frac{3}{2} ( x - 1) \\ 2y - 4 = - 3(x - 1) \\ 2y - 4 = - 3x + 3 \\ 3x + 2y - 4 - 3 = 0[/tex]
We have the final answer as
[tex]3x + 2y = 7[/tex]
Hope this helps you

marissa has $4.40 in quarters and dimes. if she has 5 more quarters than dimes how many of each coin does she have?
Answer:
22
Step-by-step explanation:
Marissa has $4.40 quarter and dimes
she has 5 more quarters than dimes
that means she times
$4.40×5=22
Answer:
Dimes = 9 dimes.
Quarters = 14 quarters.
Step-by-step explanation:
Q = D + 5 (1)
25×Q + 10×D = 440. (2)
From eq(1) substitute the expression for Q into equation (2)
25×(D+5) + 10D = 440
25D + 125 + 10D = 440
35D = 440 - 125
35D = 315
D = 315/35
D = 9
so,
Dimes = 9 dimes.
and,
Quarters = 9+5
= 14 quarters.
Prove:25×Q + 10×D = 440
25×14 + 10×9 = 440
350 + 90 = 440
440 = 440

Give two points with integer coordinates that have a slope of 10/7 between them
Answer:
(0,0) and (7,10)
Step-by-step explanation:
recall that the slope - intercept form of a linear equation can be given as
y = mx + b
where m = slope and b = y intercept
in our case, we are given that slope, m = 10/7, hence our equation becomes
y = (10/7) x + b
since we are not given any information about the y-intercept, we can simply pick a value for b that is most convenient for us.
We pick b = 0, hence the equation simplifies to:
y = (10/7) x ----- eq 1
we can see immediately that if x = 0, y must also = 0
proof if x = 0:
y = (10/7)(0) =0
since 0 is an integer, then (0,0) must be the first point.
we can also observe that for y to be an integer, we must get rid of the denominator 7. We can do this by multiply the right side by 7. Hence we let x = 7:
y = (10/7) x 7
y = 10
hence (7,10) is the second point.

What are the coordinates of point B on AC such that the ratio of AB to AC is 1:3
Answer:
B) (2/3, 3 2/3)
Step-by-step explanation:
I think whoever write this problem thought the distance from A to C was 10. It’s not. It’s 10.77. (See below). But following what they did, the answer must be B) (2/3, 3 2/3)
First, find the distance from A to C.
4²+10²=c²
16+100=c²
116=c²
c=√116
10=10.77
The coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
What is a segment bisector?A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.
It is given that:
The line segment shown in the picture is in the ratio of AB to AC is 1:3
AB : AC = 1 : 3
m : n = 1 : 3
The coordinate of point A is (2, 7)
The coordinate of point C is (-2, -3)
Let the coordinate of the point B is (x, y)
m = 1
n = 2
x1 = 2
x2 = -2
y1 = 7
y2 = -3
x = (-2+4)/3
x = 2/3
y = (-3+14)/3
y =11/3
y = 3 2/3
B = (x, y) = (2/3, 3 2/3)
Thus, the coordinates of point B on AC such that the ratio of AB to AC is 1:3 is (2/3, 3 2/3) option (B) is correct.
The options are:
A. (1/3, 2 5/6)
B. (2/3, 3 2/3)
C. (-2/3, 1 1/6)
D. (-2/3, 1/3)

Bill has $6 more than Ted. Together they have $32. Write two equations and then solve for the amount of money that bill has.
Someone alr told me the was $19 but I NEED the equation part
Answer:
B= Bill's money
T= Ted's money
B+T=32
T+6=B
Step-by-step explanation:
If you rearrange the first equation you get:
B=32-T
You can then substitute the B in that equation with T+6:
T+6=32-T
combine like terms to get T:
2T+6=32
2T=26
T=13
Then plug in 13 for T in either of the first equations to get B:
13+6=B
19=B
Answer:
Bill has 19$
Step-by-step explanation:
Bill = b
Ted = t
b = t + 6$
b - t = 6$------equation 1
b + t = 32$------equation 2
(equation 1 - equation 2)
(b - b) + (-t - t) = 6 - 32
0 - 2t = -26
-2t = -26
t = -26/-2
t = -26/-2
t= 13$
(put t = 13$ in equation 1)
b - (13) = 6
b - 13 = 6
b = 6 + 13
b = 19$ (Bill = 19$)
(x^2+4)^2−11(x^2+4)+24=0
find one solution for this equation
Answer:
Step-by-step explanation:
(x²+4)²-11(x²+4)+24=0
put x²+4=y
y²-11y+24=0
y²-3y-8y+24=0
y(y-3)-8(y-3)=0
(y-3)(y-8)=0
y=3,8
so x²+4=3
x²=-1=i²
x=±i
or x²+4=8
x²=4
x=±2

An opinion poll surveyed 900 people and reported that 36% believe a certain governor broke campaign financing laws in his election campaign.a. Calculate a 95% confidence interval for the population proportion of people who believe the governor broke campaign financing laws. (Round your answers to three decimal places.)
Answer:
The confidence Interval = (0.329, 0.391)
Step-by-step explanation:
Formula for the Confidence Interval for proportion =
p ± z × √p(1 - p)/n
where
p = x/n
From the question
n = 900 people
x = 36% of 900 people
= 36/100 × 900
= 324
z = z score of 95% confidence Interval
z = 1.98
p = x/n
= 324/900
= 0.36
Confidence Interval = p ± z × √p(1 - p)/n
= 0.36 ± 1.96 × √0.36 (1 - 0.36)/900
= 0.36 ± 1.96 ×√0.36 (0.64)/900
= 0.36 ± 1.96 × √0.000256
= 0.36 ± 1.96 × 0.016
= 0.36 ± 0.03136
Confidence Interval = 0.36 ± 0.03136
= 0.36 - 0.03136
= 0.32864
Approximately to 3 decimal places = 0.329
= 0.36 + 0.03136
= 0.39136
Approximately to 3 decimal places = 0.391
Therefore, the 95% confidence interval for the population proportion of people who believe the governor broke campaign financing laws = (0.329, 0.391)
