On one day Fred’s Sports World sold 9 Buffalo Bills jerseys and 3 Miami Dolphin jerseys for a total of $899.40. The next day they sold 12 Bills jerseys and only 2 Dolphins jerseys for a total of $1139.30. How much is the Bills jersey and how much is the Dolphins jersey?
Answers
Given:
Let x be the cost of the Buffalo Bills jersey.
Let y be the cost of the Miami Dolphin jersey.
According to the question, we have
9x+3y=899.40.......(1)
12x+2y=1139.30.....(2)
From (1),
[tex]\begin{gathered} 3y=899.40-9x \\ y=299.8-3x\ldots\ldots(3) \end{gathered}[/tex]Substitute equation (3) in equation (2), we get
[tex]\begin{gathered} 12x+2(299.8-3x)=1139.30 \\ 12x+599.6-6x=1139.30 \\ 6x=539.7 \\ x=89.95 \end{gathered}[/tex]Then the value of y is,
[tex]\begin{gathered} y=299.8-3(89.95) \\ y=29.95 \end{gathered}[/tex]Hence, the cost of the Buffalo Bills jersey is $89.95, and the cost of the Miami Dolphin jersey is $29.95.
The radius of a circle can be approximated using the expression sqrt(((A)/(3))) where A represents the area . A circular kiddie swimming pool has an area of about 28 square feet . An inflatable full-size circular pool has an area of about 113 square feet , how much greater is the radius of the full-size pool than the radius of kiddie pool? Round to the nearest whole number .
Answers
The radius of the full-size pool is 2 times greater than the radius of kiddie pool
How to determine the ratioThe formula for determining the area of a circle is expressed mathematically as;
Area = πr²
Where;
r is the radius of the circleπ has a value of 3.142From the information given, we have that;
Radius = √A/3
Where;
A is the radius of the circle
For the circular kiddie, we have;
Radius = √28/3
Find the ratio
Radius = √9. 3
Find the square root
Radius = 3 feet
For the circular pool
Radius = √ 113/3
Find the ratio
Radius = √37. 66
Find the square root
Radius = 6 feet
We then have;
Radius of the pool/radius of the kiddie pool

Right 4 up 6: (4,6)
Left 4 up 6: (-4, 6)
Down 4 right 6: (6, -4)
Right 6 down 4: (6, -4)
Answer: Right 4 up 6 is (4,6), left 4 up 6 is (-4,6), and right 6 down 4 is (6, -4).
Step-by-step explanation: Since you're starting from the origin, it's mainly counting. For (4,6), you are moving 4 places from 0 on the x axis. Then you move up 6 spaces from 4 on the y-axis. If you didn't move up, you'd be stuck at (4,0). It's important to keep in mind that (x,y).
A tent pole that is 9 feet tall is secured to the ground with a piece of rope that is 15 feet long from the top of the tent pole to the ground. Determine the number of feet from the tent pole to the rope along the ground.
Answers
Answer:
12 ft
Step-by-step explanation:
To find the base (b), you would first need to sketch a right triangle using the following:
a = 9
c = 15
Using the Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex], you would change it to [tex]c^{2} -a^{2} =b^{2}[/tex] to fit the question. Next, you would plug in the numbers to the corresponding letter.
[tex]15^{2} -9^{2} =b^{2}[/tex]
[tex]225-81=144^{2}[/tex]
[tex]\sqrt{144} =b[/tex]
[tex]12=b[/tex]
The horizontal distance from the tent pole to the rope along the ground will be equal to 12 feet.
What is the Pythagoras' Theorem?According to the Pythagoras theorem, if a triangle has a straight angle (90 degrees), the hypotenuse's square is equal to the total of its other two sides' squares.
As per the given in the question,
Height of tent pole, p = 9 feet
Height of rope, h = 15 feet
Let the horizontal distance from pole to rope is b.
Use Pythagoras' theorem,
h² = p² + b²
15² = 9² + b²
b² = 225- 81
b = √144
b = 12 feet.

Agnes, evangelina, isabela, omar, and yuri each made a tower using wooden blocks. each person used a different number of blocks in their tower, and the mean (average) number of blocks in each tower was 25 . yuri used the most blocks in her tower, and agnes used the fewest blocks in her tower. if yuri used 32 blocks, determine the minimum possible number of blocks that agnes could have used.
Answers
Given a block play problem, the minimum number of blocks Agnes can use to build a tower is 3 or 1.
To calculate the average (mean) of a set of values, first divide by the number of values in the set. Therefore, the sum of the values in the set is equal to their average multiplied by the number of values in the set. The average number of blocks in each tower was 25, and since there were 5 towers, the total number of blocks used was 5 × 25 = 125. Yuri's Tower used 32 blocks, so the remaining towers used a total of 125 minus 32 = 93 blocks.
To find the minimum possible number of blocks for Agne's tower, let the other three towers use as many blocks as possible. Now we know that Yuri's tower used the most blocks and each tower used a different number of blocks. So the other 3 towers can use up to 31, 30 and 29 blocks respectively. The result was an absolute minimum number of blocks that Agnes could use, 93 - 31 - 30 - 29 = 3
By the way, the minimum number of blocks Agnes can use is not 93 - 32 - 32 - 32 = - 3 , but negative value is not possible. so, if everyone could use the same number of blocks. Agnes must have used at least one block, as it is possible to use a negative number of blocks.

Given the details above, the sequence of steps below shows that ABCD is a Trapezoid.
What is a Trapezoid?A trapezoid, also known as a trapezium, is a closed, flat object with four straight sides and one set of parallel sides. A trapezium's parallel sides are known as the bases, while its non-parallel sides are known as the legs.
Given:
The diagonals of the quadrilateral ABCD intersect at o where AO/BO = CO/DO; which also means that
AO/CO = BO/DO the proof is given as follows:
Create line OE || DC in a way that E lies on BC.
In ΔBDC, based on the Basic Proportionality Theory,
BO/OD = BE/EC ............................1
It is also given that:
AO/CO = BO/DO ..........................2
Hence, from Equations 1 and 2,
AO/CO = BE/EC
Thus, we can state that on the basis of the Converse of the Basic Proportionality Theorem,

Answers
The value of the car after 12 years is $15,229.50
Here, we want to calculate the value of a car that loses a percentage of its origial value after some years
To do this, we shall need an exponential equation that represents decay or depreciation
We can have this as;
[tex]P=I(1-r)^t[/tex]where;
P is the present value that we want to calculate
I represents the original value of the car which is $32,000
r is the percentage of decrease per year
From the question, there is a decrease of 18% every 3 years
The percentage decrease per year will be 18%/3 = 6%
6% is same as 6/100 = 0.06
t represents the time frame we are considering = 12 years
We proceed to input all these values into the equation above
We have it as;

Since he needs 150$ in the account for safety net, we must have
