Kiana's soccer team's ratio of wins to losses is 5:3. Her team has played 24 games. How many games have they won?
The win-to-loss ratio of 5:3 is a "part-to-part" ratio, so we can represent each part as a fraction of the whole. We can do this by simply adding 3 + 5 = 8 (the "whole") and dividing by that total. This gives us a ratio of Images, which means that the Bombers won Images of their games and lost Images of them. Since they played a total of 120 games, they won Images games and lost Images games.
we know the team has played a total of 24, and we know the wins : losses ratio is 5 : 3, so let's simply divide 24 by (5 + 3) and distribute accordingly.
[tex]\cfrac{wins}{losses}\implies \cfrac{~~5\cdot \frac{24}{5+3}~~}{3\cdot \frac{24}{5+3}}\implies \cfrac{~~ 5\cdot \frac{24}{8}~~}{3\cdot \frac{24}{8}}\implies \cfrac{5\cdot 3}{3\cdot 3}\implies \cfrac{\stackrel{\mathbb{WINS}}{15}}{9}[/tex]
here a subtraction problem that has been solved incorrectly what is the right answer for 74-25=59 but do it in the addition sentence that check the subtraction problem
Answer:
Answer:
the equation is wrong
Step-by-step explanation:
=> 74-25=59
since 74 - 25 equals to 59 in order to find the addition sentence that will check the subtraction problem is true and 59 and 3/5 or you can add add 59 and 25 to check if the problem was solved correctly
=> 59+25
add 59 to 25
=> 84
this means the question is wrong
What is the value of x if the angles are supplementary?
1.) 60
2.) 50
3.) 40
4.) 30
Answer:
2) 50
Step-by-step explanation:
Basically, supplementary is when you add two angles, they should equal 180 degrees. In this picture, we can see that the bottom two rays form a straight line, indicating that it is a 180-degree angle, also. Great way to visualize, by the way. Well, 180 - 130 is 50 degrees, so x is equal to 50 degrees.
Answer:
2) 50
Step-by-step explanation:
x + 130 = 180
-130 -130
x = 50

A circle has a diameter of 28 centimeters.
Estimate the area of the circle. Use
3.14
or
22
___
7
for
π
.
Answer:
616 square centimeters
Step-by-step explanation:
Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.
Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.
Multiply 14 squared by 22/7:
(22/7)(14^2)
This gives us (22/7)(196); (4312/7); 616.
Therefore, the area of the circle is approximately 616 square centimeters.

Answer:
y=(x+2)(x-5)
Step-by-step explanation:
The roots of the function (where it touches the x axis) are (0,-2) and (0,5), so you have to pick the equation with those roots. This equation if y=(x+2)(x-5). This is because when y = 0, when you insert those roots as x values the right side also equals zero. For example:
0=(x+2)(x-5)
set x as -2
0=(-2+2)(-2-5)
0=0*-7
0=0
The same would also happen if you inserted 5, showing that this equation is the correct one for this set of roots.

a. How long should a guy wire be if it is to connect to the top of the tower and be secured at a point on the sloped side 100 feet from the base of the tower?
b. How long should a second guy wire be if it is to connect from the base on the flat side?
Answer:
a. 493 ft.
b. 269 ft.
Step-by-step explanation:
Please see the attached pictures.
a. Since we are interested in the length of AD, and ∆ABD does not have a right angle, we should think about using sine rule or cosine rule. We are only given two lengths in ∆ABD thus let's find one more angle, ∠ABD.
∠ABD= ∠ABC -∠CBD
∠CBD= 10° (given)
Since the tower should be vertically upright from the ground, we can assume that ∠ABC is 90°.
∠ABD= 90° -10°
∠ABD= 80°
With 2 lengths and 1 angle, we can apply cosine rule to find the length of the 3rd side:
[tex]\textcolor{steelblue}{{ {c}^{2} = {a}^{2} + {b}^{2} - 2abcosC}}[/tex]
(AD)²= 500² +100² -2(500)(100)(cos80°)
After simplifying and taking the square root of both sides, we obtain:
AD= 492.58 (5 s.f.)
AD= 483 (3 s.f.)
Thus, the guy wire has to be [tex]\textcolor{red}{{483 ft}}[/tex].
__________
b. Here, we make the assumption that the 500 ft. is excluding the height of the antenna and each square unit has the same height.
The tower is made up of 12 boxes, while the second guy wire is connected to the 6th box of the tower from the ground.
12 boxes ----- 500 ft
6 boxes ----- 500 ÷2= 250 ft
Pythagoras' Theorem states that in a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides.
Applying Pythagoras' Theorem,
x²= 100² +250²
x²= 72500
Taking the square root of both sides:
x= 269.26 (5 s.f.)
x= 269 (3 s.f.)
Thus, the length of the second guy wire is [tex]\textcolor{red}{{269 ft}}[/tex].
Answer:
a) 493 ft (nearest foot)
b) 269 ft (nearest foot)
Step-by-step explanation:
Part a
The guy wire creates a triangle with the tower with the following:
longest side = 500 ftshortest side = 100 ftangle between longest side and shortest side = 90 - 10 = 80°Therefore, as we have an angle with 2 adjacent side lengths, we can use the cosine rule to find the length of the unknown side opposite the angle.
cosine rule: c² = a² + b² - 2ab cos C
(where C is the angle, a and b are the sides adjacent the angle, and c is the side opposite the angle)
Substituting given values into the equation and solving for c:
c² = a² + b² - 2ab cos C
⇒ c² = 500² + 100² - 2(500)(100) cos(80°)
⇒ c² = 260000 - 100000cos(80°)
⇒ c = √[260000 - 100000cos(80°)]
⇒ c = 492.5801277...
Therefore, the length of the guy wire that is connected to the top of the tower and is secured at a point on the sloped side 100 ft from the base of the tower is 493 ft (nearest foot).
Part b
From inspection of the diagram, we can see that the second (left) guy wire is attached halfway up the height of the tower.
This guy wire creates a right triangle with the tower with the following:
height = 500 ÷ 2 = 250 ftbase = 100 ftTherefore, as we have the length of both legs of a right triangle, we can use Pythagoras' Theorem to find the length of the wire:
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Substituting given values into the equation and solving for c:
a² + b² = c²
⇒ 100² + 250² = c²
⇒ c² = 72500
⇒ c = √(72500)
⇒ c = 269.2582404...
Therefore, the length of the second guy wire is 269 ft (nearest foot)

• Food & Drink $250
• Game Tokens $100
• Other $70
A.
$84
B.
$336
C.
$378
D.
$42
Answer:
C. $378
Step-by-step explanation:
Total cost of party = food & drink + game tokens + other
= 250 + 100 + 70
= $420
Deposit = 10% of total cost
= 10% of $420
= 0.1 x 420
= $42
Total cost still to pay = total cost - deposit
= 420 - 42
= $378
Can someone help me with this
Answer:
Bottom box= 103/210
Middle-right box=19/30
Middle-left box=7/21
Step-by-step explanation:
we can convert 1/7 to 21ths so it will be easier to add.
1/7 = 3/21
so, 3/21 + 4/21 = 7/21
we can now use that to find the box next to it.
The LCM (lowest common multiple) of 21 and 30 is 210.
7/21 = 70/210
29/30 = 203/210
so 203/210-70/210 = 19/30 (simplified)
and finally, we can use this to work out the fraction in the bottom box.
LCM of 30 and 7 is also 210.
so 1/7 = 30/210
19/30 = 133/210
so 133/210 - 30/210 = 103/210.

A tube of tennis balls has the following measures: 4-inch diameter and a height of 8 inches. What is the surface area of the tube of tennis balls? (Use 3.14 for π.)
A)301.44 in.^ 2
B)226.08 in. ^2
C)213.52 in. ^2
D)125.6 in. ^2
The surface area of the tube of tennis balls is 125.6 inches
What is the surface area of the tube of tennis balls?The given parameters are:
Diameter, d = 4 inches
Height = 8 inches
Start by calculating the radius (r)
Radius (r) = Diameter/2
So, we have
r = 4 inches/2
Evaluate
r = 2 inches
The surface area of the tube of tennis balls is calculated as:
Surface area = 2πr(r + h)
So, we have:
Surface area = 2 * 3.14 * 2 * (2 + 8)
Evaluate the product
Surface area = 125.6 inches
Hence, the surface area of the tube of tennis balls is 125.6 inches

3. Which of these numbers, when rounded off to the nearest 1000, gives 99 000? 98 833; 99 583; 99 374; 98 476, 98 783; 99 574; 98 587
Answer:
98,833 98,783 98,587
Step-by-step explanation:
These numbers go up to 99,000 because... the 8 in each of these numbers ask the hundreds place numbers if he can go up.
And if those numbers are 5 and above they can which leads to the 8 going up to 9 making 99,000
for the first one 98,833 it can go up because hundreds place number is a 8 so because of 8 being 5 and above it can go up.
For the second number 98,783 it can go up because the hundreds place number 7 is 5 and above so it can go up.
And for our last number 98,587 it has a 5 in it's hundreds place number so it just makes the cut to go up so those are numbers.
