The tennis team has played 28 matches so far this season. They have won 10 matches so far. How many matches will the team need to win for the team to have a 55% success rate?
Answers
Answer: they would have to win 22/40 games
Step-by-step explanation:
22 divided by 40 is 0.55 or 55%
Answer:
x = 12 (I took the FLVS assignment for 04.04, and I'll show you guys how to do this!)
Step-by-step explanation:
The team has completed 28 matches so far and has won 10 of them.
The current success rate is:
[tex]r=\frac{10}{28} *1.00=.35714[/tex]
(1.00 = 100% and .35714 = 35.714%)
We need the success rate to be 55%
Then the team must win a number of "x" matches, so:
[tex]r=\frac{10+x}{28+x} =0.55[/tex]
Now we solve the equation for x:
[tex]\frac{10+x}{28+x} =0.55[/tex]
[tex]10+x=0.55(28+x)[/tex](distributive property here!)
[tex]10+x=15.4+0.55x[/tex]
Now, move the 0.55x to the other side by subtracting it from both sides:
[tex]10+x-0.55x=15.4[/tex]
And move the 10 by doing the same thing (subtracting from both sides):
[tex]x-0.55x=15.4-10[/tex]
[tex]0.45x=5.4[/tex]
(You might ask: 15.4 - 10 = 5.4, but how do you get 0.45x out of x - 0.55x? Use Quick Math, and you should get the answer!)
[tex]x=\frac{5.4}{0.45}[/tex]
[tex]x = 12[/tex]
So, by following these steps, x = 12 is your answer!
The team must win 12 matches to have a success rate of 55%.
Hope this helps! Have a wonderful day!
how are ASA and AAS used to show that triangles are congruent?
Answers
Answer:
If two pairs of corresponding angles and the side between them are known to be congruent, the triangles are congruent. This shortcut is known as angle-side-angle (ASA). Another shortcut is angle-angle-side (AAS), where two pairs of angles and the non-included side are known to be congruent.
In ASA, two angles and one common side is equal and in AAS one not common side and two angles are equal.
What is triangle?Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes is represented by the symbol and consists of three connected vertices.
The ASA congruence means, there will be two corresponding angles and one side between them will be equal, then the triangles are congruent.
The AAS congruence means, there will be two corresponding angles and one side excluded from them will be equal, then the triangles are congruent.

A jewelry artist is selling necklaces at an art fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $12 each. The inequality LaTeX: 12n > 135 + 4.50n12 n > 135 + 4.50 n represents the situation in which the artist makes a profit. Will the artist make a profit if she sells 15 necklaces? Show how you know. Be sure to indicate what the variable n represents.
Answers
Answer:
The artist will make a profit if she sells 15 necklaces. This is known because 15 is greater than 11.625 (i.e. 15 > 11.625).
Step-by-step explanation:
Note: The question contains some error. The question is therefore rewritten before is answered as follows:
A jewelry artist is selling necklace at an art fair. It costs $135 to rent a booth at the fair. The cost of material for each necklace is $4.50. The artist is selling the necklace at $12 each. The inequality 12n>135+4.50 represents the situation in which the art is making the profit. Will the artist make a profit if she sells 15 necklaces? Show how you know. Be sure to indicate what the variable n represents.
The explanation of the answer is therefore given as follows:
Given;
12n > 135 + 4.50 .................... (1)
Where n represents the number of necklace that must be sold by the artist to make a profit.
Solving for n from equation, we have:
12n > 139.50
n > 139.50 / 12
n > 11.625 ..................... (2)
Equation (2) implies that more than 11.625 necklaces must be sold by the artist to make a profit.
When the artist sells 15 necklaces, it implies that n = 15.
Since more than 11.625 necklaces must be sold by the artist to make a profit, it therefore implies that the artist will make a profit if she sells 15 necklaces. This is known because 15 is greater than 11.625 (i.e. 15 > 11.625).

the perimeter is P=2L+2W
you can plug in the values

plug in 442 for P
442= 2(4w- 9) + 2W

The slope of the given line is -4
Step-by-step explanation:
The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
In the given figure
∵ The line passes through the points (-6, 5) and (-4, -3)
∴ x1 = -6 and y1 = 5
∴ x2 = -4 and y2 = -3
→ Substitute them in the formula of the slope above
∵ m = [tex]\frac{-3-5}{-4--6}[/tex]
∴ m = [tex]\frac{-8}{-4+6}[/tex]
∴ m = [tex]\frac{-8}{2}[/tex]
∴ m = -4
∴ The slope of the given line is -4
