Answer:
34.2
Step-by-step explanation:
The original sale price of an item at markdowns is $110.95. You have an additional 20% off coupon for markdowns for purchases totaling $90.00 or more. Using the coupon, how much more do save when compared to the original sale price?
Answer:
$22.19
Step-by-step explanation:
20% off the original price = $110.95 - (20% x $110.95)
20% x $110.95 = $22.19
$110.95 - $22.19 = $88.76
difference = $110.95 - $88.76 = $22.19
Answer:
You will save $22.19 when compared to the original sale price.
Step-by-step explanation:
The original sale price of an item at markdowns is $110.95.
You have an additional 20% off coupon for markdowns for purchases totaling $90.00 or more.
So, this becomes:
[tex]0.20\times110.95=22.19[/tex] dollars
Hence, you will save $22.19 when compared to the original sale price.

(−10,−7) and (−3,−10)
Answer:
M = (-13/2, -17/2)
Step-by-step explanation:
The midpoint of two points is half-way between the x-values and the y-values.
The formula is
M = ((x₁ +x₂)/2, (y₁ + y₂)/2)
For the points (−10,−7) and (−3,−10),
M = ((-3 + (-10))/2), (-10 + (-7))/2))
M = ((-3 - 10)/2), (-10 - 7)/2))
M = (-13/2, -17/2)
The graph below shows your two points at (−10,−7) and (−3,−10) and the mid-point at (-13/2, -17/2).
A string of a kite is 100 meters long and it makes an angle of 60° with horizontal. Find the height of the kite and then find the ground distance from the kite to the person flying the kite,assuming that there is no slack in the string.
1. Draw a figure for the information given in the problems.
2. Using the correct trig function, write out the mathematical problem.
3. Solve the problem to find the missing sides.
Answer:
Height of the kite is [tex]=50 \sqrt{3}[/tex] meters.
Ground distance from the kite to the person flying the kite is 50 meters.
Step-by-step explanation:
Given that a string of a kite is 100 meters long and it makes an angle of 60° with horizontal.
Which mans we are getting a shape of right angle triangle as shown in picture. Where "y" is the height of the kite and "x" is the ground distance from the kite to the person flying the kite. Now we can use trigonometric ratios to find the values of x and y.
[tex]\sin\left(60^o\right)=\frac{\left[opposite\right]}{\left[hypotenuse\right]}=\frac{y}{100}[/tex]
[tex]\sin\left(60^o\right)=\frac{y}{100}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{y}{100}[/tex]
[tex]\frac{\sqrt{3}}{2}*100=y[/tex]
[tex]50 \sqrt{3}=y[/tex]
Hence height of the kite is [tex]=50 \sqrt{3}[/tex] meters.
similarly:
[tex]\cos\left(60^o\right)=\frac{\left[adjcent\right]}{\left[hypotenuse\right]}=\frac{x}{100}[/tex]
[tex]\cos\left(60^o\right)=\frac{x}{100}[/tex]
[tex]\frac{1}{2}=\frac{x}{100}[/tex]
[tex]\frac{1}{2}*100=x[/tex]
[tex]50=x[/tex]
Hence ground distance from the kite to the person flying the kite is 50 meters.
The height of the kite and the distance from kite to person are 86.6 meters and 50 meters respectively.
Using Trigonometry concept ;
The height of the kite , y can be obtained thus ;
Sine = opposite / HypotenusSin(60°) = y / 100
y = sin(60°) × 100
y = 86.6 meters
B.)
The distance from the kite to the person would be ;
Tangent = opposite / AdjacentTan(60) = 86.6667 / x
d = 86.6667 / Tan(60)
d = 50 meters
Therefore, the height of the kite and the distance from kite to person are 86.6 meters and 50 meters respectively.

a vehicle with power steering makes a hissing or whirring sound when the wheel is turned all the way to the stops. Technician A says that this is a normal condition. Technician B says a loud squealing noise during sharp turns may be caused by worn ball joints. who is correct?
Answer:
Technician B only
Step-by-step explanation:
Clunking Noises From the Front Suspension. One of the most common symptoms of a problem with suspension ball joints is clunking noises coming from the vehicle's front suspension. ... Usually, the clunking will get continuously louder as the ball joints wear out, or until they eventually completely fail and break.
Final answer:
Technician B is correct. A loud squealing noise during sharp turns may be caused by worn ball joints and indicates a potential issue with the suspension system.
Explanation:
Technician B is correct. A loud squealing noise during sharp turns can indeed be caused by worn ball joints. This indicates a potential issue with the suspension system which includes components like ball joints. On the other hand, a hissing or whirring sound when the wheel is turned all the way to the stops in a vehicle with power steering is not typically considered a normal condition.
Find the larger of two consecutive integers if the larger is 149 less than twice the smaller.
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
Check:
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
Final answer:
The larger of the two consecutive integers is 151, determined by setting up an algebraic equation based on the given condition and solving for the smaller integer first.
Explanation:
The student is asked to find the larger of two consecutive integers given that the larger is 149 less than twice the smaller. Let's denote the smaller integer as n. Thus, the larger integer would be n + 1. According to the problem, we have the equation (2n) - 149 = n + 1, which simplifies to n = 150, making the larger integer 151.
Jackson is buying a good chain that had an original price of $795 but is advertised as 65% off. Sales tax of 8.50% is applied tot he discounted price. How much will Jackson pay for the chain ?
To find out how much Jackson will pay for the gold chain, you calculate the discount price by subtracting 65% of the original price from the original price, then apply an 8.50% sales tax to the discounted price, and add it to the discounted price to get the total cost. Jackson will pay a total of $301.90 for the gold chain.
Jackson is planning to buy a gold chain with an original price of $795 which is advertised at a 65% discount. The formula to calculate the discount price is:
Discount Price = Original Price - (Discount percentage x Original Price)First, we convert 65% to a decimal, which is 0.65:
Discount Price = $795 - ($795 x 0.65)Then, calculate the discount:
Discount Price = $795 - ($516.75)So after the discount, the price becomes:
Discount Price = $278.25On this discounted price, a sales tax of 8.50% is applied. Converting that to decimal will be 0.085 and now we multiply it with the discounted price:
Sales Tax Amount = 0.085 x $278.25Now, find the amount of sales tax:
Sales Tax Amount = $23.65125Round the sales tax to the nearest cent:
Sales Tax Amount = $23.65Finally, add the original discount price and the sales tax:
Total Price = Discount Price + Sales Tax AmountTotal Price:
Total Price = $278.25 + $23.65 = $301.90Jackson will pay $301.90 in total for the gold chain after applying the discount and sales tax.

Step-by-step explanation:
a farmer bought a number of pigs for $180. However, 3 of them died before he could sell the rest at a profit of 8 per pig. His total profit was $109. how many pigs did he originally buy?
The farmer originally bought 41 pigs.
Let x be the number of pigs the farmer originally bought.The total cost of the pigs is $180.After 3 died, he was left with x - 3 pigs.He sold these pigs at a profit of $8 per pig,Resulting in a total profit of 8(x - 3).We know his total profit was $109. So, we can set up an equation:Profit = Selling price - Cost price8(x - 3) = 109 (his total profit) + 180 (cost price)
Combining like terms:8x - 24 = 289
Adding 24 to both sides:8x = 313
Dividing both sides by 8:x = 39.125
Since the farmer can't buy parts of pigs, we round x up to the nearest whole number, which is 40.However, there's a slight discrepancy because the profit wouldn't be exactly $109 if he had 40 pigs. This is because the profit is calculated per pig, and a fraction of a pig wouldn't generate a proportional profit.Therefore, let's try with x = 41:Profit = 8(41 - 3)= 8 * 38
= $304
Total earnings = Profit + Cost price= $304 + $180 = $484
Since the cost price is $180 and the total earnings are $484,The profit would be $484 - $180 = $304, This matches the calculation with 8 pigs sold at a profit of $8 each.Therefore, the farmer originally bought 41 pigs.

The answer would be 7.2 centimeters.
C. 7.2 centimeters
How do you calculate the Pythagorean theorem?a 2 + b 2 = c 2. This is known as Pythagorean equation, named after the ancient Greek thinker Pythagoras. This relationship is useful because if 2 sides of the right triangle are known, the Pythagorean theorem could be used to determine the length of the 3rd side. Referencing the above diagram, if. a = 3 and b = 4
Using the Pythagorean theorem we can find the height of the triangle:
height = √(14^2 - 12^2)
height = √(196 - 144)
height = √52
height = 7.2
The answer would be 7.2 centimeters.

write an equation for the nth term of the geometric sequence 5, 10, 20, 40
Final answer:
The nth term of the geometric sequence 5, 10, 20, 40 is given by the formula T_n = 5 × 2ⁿ⁻¹.
Explanation:
To write an equation for the nth term of the geometric sequence 5, 10, 20, 40, we need to determine the first term (a) and the common ratio (r). In this sequence, the first term a=5 and the common ratio r can be found by dividing the second term by the first term (r=10/5=2).
The formula for the nth term (Tn) of a geometric sequence is given by Tn = a × rⁿ⁻¹.
So, for the given sequence, the nth term can be expressed as:
Tn = 5 × 2ⁿ⁻¹.

A graph of a trapezoid can have diagonals with slopes that are negative reciprocals and two pairs of adjacent sides that are congruent. True or False Explain your reasoning.
Answer: False
Explanation: What this statement describes is not a trapezoid, but rather a kite. A kite is a quadrilateral with two sides that are next to each other (ie adjacent) that are congruent. This is the result of combining two congruent triangles together. The diagonals of any kite are perpendicular, which is another way of saying "the diagonals have slope that are negative reciprocals".
If you had adjacent sides congruent, and a pair of parallel opposite sides, then the other two opposite sides must be parallel as well, but this would make the figure a parallelogram and not a trapezoid. This is another way to see why the answer is false.

It takes you 5 hours to complete a 375 kilometer trip. What was your average speed on this trip? Henry takes a boat ride for 15 minutes to reach his destination. If the boat was traveling at 6 meters/second, how far did the boat travel? A storm is moving east towards your house at an average speed of 35 km/hr. If the storm is currently 80 kilometers from your house, in how much time do you expect it to arrive? If the velocity of an object changes from 15 m/s to 50 m/s during a time interval of 4 s, what is the acceleration of the object? If the acceleration in problem 4 is constant, what's the average velocity of the object in the previous problem? Using the information provided and calculation in problems 4 and 5, find the distance traveled within that 4 s period. A truck decelerates at a rate of 2 m/s2. If it starts with a velocity of 15 m/s, how long will it take to stop? An object with a starting velocity of 15 m/s accelerates at 3 m/s2. How far does the object travel within 10 seconds?
Answer:
1. 75 kilometers per hour
2. 5.4 kilometers
3. I expect the storm to arrive 2.3 hours.
4. Acceleration = 8.75 [tex]m/s^{2}[/tex]
5. 200 meters
6. The truck will take 7.5 seconds to stop
7. The object travels 150 meters within 10 seconds
Step-by-step explanation:
1. Average speed = [tex]\frac{distance}{time}[/tex]
[tex]= \frac{375}{5}[/tex]
= 75 kilometers per hour
2. Distance = speed × time
Time taken = 15 minutes
= 15 × 60
= 900 seconds
Distance = 6 × 900
= 5400 meters
= 5400/1000
= 5.4 kilometers
So, the boat traveled 5.4 kilometers.
3. Time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{80}{35}[/tex]
= 2.286
So, I expect the storm to arrive in 2.3 hours.
4. Acceleration = Rate of change of velocity
= [tex]\frac{50-15}{4}[/tex]
= [tex]\frac{35}{4}[/tex]
= 8.75 [tex]m/s^{2}[/tex]
5. Distance = speed × time
= 50 × 4
= 200 meters
6. Time = [tex]\frac{velocity}{acceleration}[/tex]
= [tex]\frac{15}{2}[/tex]
= 7.5 seconds
The truck will take 7.5 seconds to stop
7. Distance = Velocity × Time
= 15 × 10
= 150 meters
Hence, the object travels 150 meters within 10 seconds.

A geometric sequence is shown below: 66 a0, -11, 22, 56 a1, 88, -176. A) What is the common ratio for this geometric sequence? 69 a2 B) What are the missing terms in the geometric sequence shown above?
Answer:
Step-by-step explanation:
Given a geometric sequence as
66 a0, -11, 22, 56 a1, 88, -176
We have to find the common ratio and also the missing numbers.
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Hence by comparing two consecutive numbers let us find common ratio.
Consider 88 and -176. -176 = 88(-2) Hence common ratio is -2
a0 = -11/-2 = 5.5
a1 = 88/-2 = -44
Missing terms are -132 and 5.5
common ratio = -2

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
