Rick is buying a $115 tennis racquet from a sporting goods store. If the racquet is on sale for 35% off and sales tax is 8%, how much will he pay in total?
Answer:
$79.65
Step-by-step explanation:
115-40.25= 73.75
73.75 x 0.08 = 5.90
73.75 + 5.90 = 79.65
Rick will pay 80.73 dollar in total.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Rick is buying a $115 tennis racquet from a sporting goods store.
If the racquet is on sale for 35% off and sales tax is 8%,then
First,we need to find 35% of 115.
35% as a decimal is 0.35
0.35 x 115 = 40.25
Now, subtract 40.25 from 115;
115 - 40.25 = 74.75
Now, the sales tax, find 8% of 74.75.
8% as a decimal is 0.08
0.08 x 74.75 = 5.98
Now, subtract add 5.98 to 74.75;
5.98 + 74.75 = 80.73
Therefore, he will pay 80.73 dollar in total.

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ohms?
Answer:
0.102048 ampere
Step-by-step explanation:
I α k / R
Current = 1/5 ; R = 8750
What is the current when the resistance is 17150 ohms
First obtain the value of k :
I = k/R
I = 1/5 ampere = 0.2 A
0.2 = k / 8750
k = 1750
What is the current when the resistance is 17150 ohms
I = 1750 / 17150
I = 0.1020408
I = 0.102048 ampere
Explain how to write an equivalent expression by combining like terms.
w + 10 + w – 4
Answer:
To combine like terms, add the variable terms together and then add the constants together. When you combine the variable terms, you have 1w + 1w, which is 2w. When you combine the constants, you have 10 – 4, which is 6. The equivalent expression is 2w + 6.
Step-by-step explanation:
Answer:
add both "w" which equals 2w. Then add 10 and -4 which is 6. So the answer is 2w+6... I'm pretty that's the answer make sure to double-check though

In the year 2009, a company made $8.4 million in profit. For each consecutive year
after that, their profit increased by 14%. How much would the company's profit be in
the year 2011, to the nearest tenth of a million dollars?
Answer:
$10.8 million or 10,752,000
Step-by-step explanation:
14% of 8,400,000 is 1,176,000
t = time in years
In one year, the company would make 8,400,000+(t*1,176,000)
In 2 years they make 8,400,000+(2*1,176,000) = 10,752,000
now round 10,752,000 to the nearest hundred thousand, which is 1/10 of 1,000,000.

The length and width of a rectangle, in terms of x, are x + 3 and 2x − 17, respectively. The area of the rectangle is 234 square units. (a) (6 points) DETERMINE the possible values of x
The possible values of x of a rectangle with length and width of x + 3 and 2x - 17 respectively is 15
Area of a rectangle
area of a rectangle = lw
where
l =lengthw = widthTherefore,
length = x + 3
width = 2x - 17
area = 234
Therefore,
234 = (x + 3)(2x - 17)
2x² - 17x + 6x - 51 = 234
2x² - 11x - 51 - 234 = 0
2x² - 11x - 285 = 0
Therefore,
(x - 15)(2x + 19)
Hence,
x = 15 or x = - 19 / 2
we can only use positive values. Therefore, x = 15

At the beginning of the year, Alyssa had $100 in savings and saved an additional $7
each week thereafter. Colton started the year with $55 and saved $10 every week. Let
A represent the amount of money Alyssa has saved t weeks after the beginning of the year and let C represent the amount of money Colton has saved t weeks after the
beginning of the year. Write an equation for each situation, in terms of t, and determine the famount of money Alyssa and Colton have saved in the week that they have the same amount of money saved.
Answer:
A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.
Step-by-step explanation:
Given that:
Alyssa started savings with $100
Saved amount each week = $7
A = Amount of money Alyssa have
t = number of weeks
A = 7t + 100
Colton started savings with $55
Saved amount each week = $10
C = 10t + 55
For same amount;
A = C
7t+100 = 10t+55
100-55=10t-7t
45=3t
3t=45
Dividing both sides by 3
[tex]\frac{3t}{3}=\frac{45}{3}\\t=15[/tex]
Putting t=15 in Alyssa's equation
A = 7(15)+100
A = 105+100 = $205
Hence,
A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Answer:
BF = 18
Step-by-step explanation:
In triangle BCD, H is the Centroid.
Centroid of a triangle divides the median in the ratio 2 : 1.
Therefore, BH : HF = 2 : 1
Let BH = 2x & HF = x
Since, HF = 6.... (given)
So, x = 6
2x = 2*6 = 12
BH = 12
Now,
BF = BH + HF = 12 + 6
BF = 18

Kendra and Dalisay practice archery, Kendra hits the target 3 times for
every 5 misses Dalisay hits the target 5 times for every 7 misses.
Who hits the target more?
Answer:
Dalisay
Step-by-step explanation:
3/5=0.6 (Kendra)
5/7≈ 0.75 (Dalisay)
5/7>3/5, so Dalisay hits the target more.
The probability of Dalisay hitting the target is more.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
According to the given problem,
Kendra hits target 3 times for 5 misses
Probability = [tex]\frac{3}{5}[/tex]
= 0.6
Dalisay hits target 5 times for every 7 misses
Probability = [tex]\frac{5}{7}[/tex]
= 0.71
Hence, we can conclude that Dalisay hits the target more.
