Find the length of AB. 6 30 AB=[?]in
Answer:
AB ≈ 3.14 in
Step-by-step explanation:
arc AB is calculated as
AB = circumference of circle × fraction of circle
= 2πr × [tex]\frac{30}{360}[/tex]
= 2π × 6 × [tex]\frac{1}{12}[/tex]
= 12π × [tex]\frac{1}{12}[/tex]
= π ≈ 3.14 in ( to the nearest hundredth )
Clarence earns a 10% commission
on sales plus a $200 weekly salary.
In one week, his sales totaled $2100.
What was his total pay that week?
Answer:
$410
Step-by-step explanation:
Step 1
We calculate the amount of commission of sales
Commission rate = 10%
Total sales = $2100
Hence,
= 10% × $2100
= 10/100 × $2100
= $210
Step 2
The total pay of Clarence for that week
= Commission + Weekly salary
Commission = $210
Weekly salary = $200
Hence,
= $210 + $200
= $410

A television was originally priced at $522, but Sam waited to buy it until the television was on sale for 50% off. If
he paid 8% sales tax on the sale price, how much did he pay in total?
Answer:
$281.88
Step-by-step explanation:
Solve for 50% of $522:
522 × 0.50
261
Solve for sales tax:
261 × 0.08
20.88
Solve for total:
261 + 20.88
281.88
Hey can u help me with this question
Answer:
y = 3x - 1
Step-by-step explanation:
→ Substitute x = 1 into all the equations to get y = 2
y = 3x - 1 ⇔ ( 3 × 1 ) - 1 = 2
Answer:
D
Step-by-step explanation:
You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Which set of numbers can represent the side lengths, in inches, of an acute triangle? 4, 5, 7 5, 7, 8 6, 7, 10 7, 9, 12 Which set of numbers can represent the side lengths, in centimeters, of a right triangle? 8, 12, 15 10, 24, 26 12, 20, 25 15, 18, 20
Answer:
1) 5, 7, 8
2) 10, 24, 26
Step-by-step explanation:
1) For an acute triangle, the square of the longest side is less than the sum of the square of the two smaller sides.
a) 4² + 5² = 16 + 25 = 41
7² = 49 > 4² + 5². Therefore the triangle is not acute
b) 5² + 7² = 25 + 49 = 74
8² = 64 < 5² + 7². Therefore the triangle is acute
c) 6² + 7² = 36 + 49 = 85
10² = 100 > 6² + 7². Therefore the triangle is not acute
d) 7² + 9² = 49 + 81 = 130
12² = 144 > 7² + 9². Therefore the triangle is not acute
2) For a right angled triangle, the square of the longest side is equal to the sum of the square of the two smaller sides.
a) 8² + 12² = 64 + 144 = 208
15² = 225 > 8² + 12². Therefore the triangle is not a right triangle.
b) 10² + 24² = 100 + 576 = 676
26² = 676 = 10² + 24². Therefore the triangle is a right triangle.
c) 20² + 12² = 400 + 144 = 544
25² = 625 > 20² + 12². Therefore the triangle is not a right triangle.
d) 15² + 18² = 225 + 324 = 549
20² = 400 < 15² + 18². Therefore the triangle is not a right triangle.

Solve the system of equations
Answer:
(3,5)
Step-by-step explanation:
For this equation, you need to solve it like simultaneous equations. Both of these have a 4y, so that is relatively easy to do, once you know how to.
The signs in front of the 4y are different, so you add the 2 equations (to remove the ys all together).
This should be (2x+-8x)+(-4y+4y)=(-14+-4), or (2x-8x)+(4y-4y)=(-14-4).
This can be expanded to -6x+0=-18, or -6x=-18.
Dividing both sides by -6 leaves you with x=3.
To find y, substitute this x value into either equation (I picked equation 1 as it is simpler). This gives you 2(3)-4y=-14, expanded to 6-4y=-14.
From there, you subtract the 6 from both sides, to get the y alone (giving -4y=-20).
By dividing both sides by -4, you get y=5.
This means the answer is (3,5).
**This question involves simultaneous equations, so you might want to look at that. I'm always happy to help!
Complete the Law Of Sines Select the value that belongs to the green box, please somebody!
Answer: [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]
The sin(A) goes with 'a'
sin(B) goes with b
sin(C) goes with c
Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]
Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.

Which region represents the solution to the given system of inequalities?
Point C represents the solution of the inequality graph
How to get solutions of inequality graphsThe graph shows two sets of equations
y < -1/2x andy ≥ 2x + 3The first equation
y < -1/2xThis is represented by a dotted line because it does not have the equality sign. The sign represented is called the less than sign. The feature of being a dotted line helps in knowing the line that solves the equation.
Also. the solution of the less than sign is below the line this eliminates points B and A.
The second equation
y ≥ 2x + 3This is represented by a solid line since it has the equality sign present. This is read as greater than or equal to. It has two signs joined together. The solution of the greater than sign is above the line this eliminates points A and D
Hence points A, B, and D has been eliminated remaining point C hence point C represents the solution of the inequality graph

statisticians for a roadside assistance company interviewed 50{,}00050,00050, comma, 000 randomly selected United States (US) households. Of those, 15{,}59515,59515, comma, 595 reported that they had traveled 505050 or more miles from home between December 232323 and January 444. If there are 115{,}000{,}000115,000,000115, comma, 000, comma, 000 US households, approximately how many of them do the interviews suggest traveled 505050 or more miles from home at that time
Answer:
The answer is "35,868,500 people".
Step-by-step explanation:
In this question, the chance of people that have traveled above 50 miles is calculated. The chance of success is the probability.
[tex]n=50000\\\\ p=15595[/tex]
[tex]\to P(x\geq 50)=\frac{15595}{50000}=0.3119[/tex]
The population of the United States is at 1150000.
Let's determine that portion of the current population has gone more than 50 miles:
