i’ll give u brainliest What is the degree measure of x?
Answer:
134 is the ONLY correct answer
Step-by-step explanation:
This is because it is asking for X, not the interior angle that's missing. You do need that angle to find the correct answer.
All triangles are equal to 180 degrees.
180-88-46=46
And all supplementary angles are equal to 180 degrees.
Therefore, 180-46 (as that is the only known angle) makes it 134 degrees.
67, 88 are not correct as one of them isn't obtuse and the other isn't to scale, 111 isn't correct as the math backs up 134 which is also an obtuse angle

An SRS of 2,500 individuals was taken from a large city to estimate the percentage of city residents with a graduate degree. 555 people in the sample had a graduate degree. The percentage of individuals in the city with a graduate degree is estimated as 22.2%. The estimated standard error is closest to:_______a. 1%b. 10% c. 0.1%
Answer:
The option is b
Step-by-step explanation:
From the question we are told that
The sample size is n = 2500
The number with a graduate degree is k = 555
The sample proportion is [tex]\^ p = 0.222[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{\frac{\^ p (1- \^ p )}{n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.222 (1- 0.22 )}{2500 } }[/tex]
=> [tex]SE = 0.010[/tex]
Converting to percentage
[tex]SE = 0.010 * 100[/tex]
=> [tex]SE =10\%[/tex]

Kannanaski Rapids drops 70 ft vertically over a horizontal distance of 866 ft. What is
the slope of the rapids?
-0.001
-12.4
-70
-0.081
I need help ASAP :(
Answer:
0.081
Step-by-step explanation:
Given parameters:
Vertical drop = 70ft
Horizontal distance = 866ft
Unknown:
Slope of the rapids =?
Solution:
Slope is the rise or vertical height divide by the horizonal distance.
Slope = [tex]\frac{vertical drop}{horizontal distance}[/tex]
Insert the parameters and solve;
Slope = [tex]\frac{70}{866}[/tex] = 0.081
Based on the information given the slope of the rapids is 0.081.
Slope of the rapids:Using this formula
Slope of the rapids=Vertically rapid drop/Horizontal distance
Let plug in the formula
Slope of the rapids=70ft/866ft
Slope of the rapids=0.0808
Slope of the rapids=0.081 (Approximately)
Inconclusion the slope of the rapids is 0.081.

If a rectangular patio has a length that is 5 feet longer than its width and a perimeter of 54 feet, solve for the length.
1)17 feet
2)21 feet
3)16 feet
4)11 feet
Answer: (3)
Step-by-step explanation:
In this problem, we don't know the length or width. All we do know is that the length is 5 feet longer than the width, and that the perimeter is 54 feet. Both lengths plus both widths equals the perimeter. To solve this problem, you must give the width, the value of x.
Step 1: Draw a rectangle where the width is x and the length is x + 5.
Step 2: Find the sum of the lengths and the sum of the widths
2 times the length plus 2 times the width equals the perimeter
2(x + 5) + 2(x) = 54
Step 3: Solve for the width
2(x + 5) + 2(x) = 54
2x + 10 + 2x = 54 (Distributive Property)
4x + 10 = 54 (Group Like Terms)
4x = 44 (Subtraction Property of Equality)
4x/4 = 44/4
x = 11 (Division Property of Equality)
x = width = 11
Step 4: Solve for the length
x + 5 = length
11 + 5 = 16
Length = 16. So (3) must be the answer.

On a 1 mile track, Runner A has made 18 laps in the time it took Runner B to make 8 laps. If Runner A is running 5 mph faster than Runner B, how fast is each of them running?
Answer:
Runner A is running at 9 mph while runner B is running at 4 mph
Step-by-step explanation:
From online values, 4 laps make 1 mile.
We are told Runner A has made 18 laps in the time it took Runner B to make 8 laps.
This means that runner A has run in mile; 18/4 = 4.5 miles
While runner B has run in miles; 8/4 = 2 miles
Runner A is running 5 mph faster than Runner B, thus speed of runner A is;
V_b + 5 while speed of runner B is V_b.
We know that; time = distance/speed
Thus;
t_a = 4.5/(V_b + 5)
t_b = 2/V_b
Since the times are equal from the question, then;
4.5/(V_b + 5) = 2/V_b
Cross multiply to get;
4.5V_b = 2(V_b + 5)
4.5V_b = 2V_b + 10
4.5V_b - 2V_b = 10
2.5V_b = 10
V_b = 10/2.5
V_b = 4 mph
Since V_a = V_b + 5
Thus, V_a = 4 + 5 = 9 mph
Runner A is running at 9 mph while runner B is running at 4 mph
Solve absolute value inequality 4>|x+1|+2
Answer:
-3 < x <1
Step-by-step explanation:
4 > | x + 1 | + 2
1. Isolate the absolute value;
Inverse operations;
4 > | x + 1 | + 2
-2 -2
2 > | x + 1 |
2. Remove the absolute value;
The absolute value of a value is the distance it is from zero. This means that when removing the absolute value, one has to account for two possibilities; when the value within the absolute value brackets is negative, and when it is positive. In the case of dealing with absolute value inequalities, one will have to set up an inequality with this in mind.
2 > | x + 1 |
-2 < x + 1 < 2
Inverse operations
-2 < x + 1 < 2
-1 -1
-3 < x < 1
Answer:
-3<x<1

Nikko needs to get his air-conditioner fixed. The repairman will charge Nikko a flat fee
of $50 plus an additional $20 for each hour he needs to work on it.
Write an equation to represent Nikko's total cost to repair his air-conditioner. Use t for total
cost and h for hours.
Answer:
$70
Step-by-step explanation:
50+20=70
The required expression is given for the Nikko is t = 50 + 20h.
Given that,
The repairman will charge Nikko a flat fee of $50 plus an additional $20 for each hour he needs to work on it.
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
here,
t is the total cost the repairman charged to Nikko,
h is the number of hours,
repair men charges for h hours = $20h
repair men charge a flat fee of $50.
Total charge, t = 50 + 20h
Thus, the required expression given for the Nikko is t = 50 + 20h.

Recall that the length of the midsegment of a triangle, is half the length of the third side.
Let's find the following given midsegments as follows:
1. IH = ½*ZX
IH = ½*18
IH = 9
2. PQ = ½*JL
PQ = ½*4
PQ = 2
3. CD = ½*GI
CD = ½*22
CD = 11
4. LK = ½*QS
LK = ½*18
LK = 9
Calculate the actual sales since the sales and sales tax were rung up together. Assume sales tax of 6% and total sales of $33,000.
Answer:
the actual sales be $31,132
Step-by-step explanation:
The computation of the actual sales is as follows:
Let us suppose the actual sales be x
Now the sales tax be 0.06x
Now the total sales would be
x + 0.06x = $33,000
1.06x = $33,000
x = $33,000 ÷ 1.06
= $31,132
hence, the actual sales be $31,132
The same is to be considered by applying the above equation
Answer:
actual sales be $31,132

10 + 12 + 15 + 24 + 12 + 10 + 35 = 118.
3/14 + 1/14 = 2/7
1/7 + 2/7 + 2/7 + 2/7 = 1
1/7 + 3/7 = 4/7
118 + 1 + 4/7 = 119 and 4/7
