The radius of a circle is 14 meters. What is the circle circumference
Step-by-step explanation:
HERE,
redius of a circle (r)=14 meters.
we know that,
[tex]\boxed{\red{\sf{circle~ circumference=2\times \pi \times r }}}[/tex]
According to the question,
circle circumference=
[tex]\tt{2\times \pi \times 14 }[/tex][tex]\tt{2 \times \dfrac{22}{7} \times 14 }[/tex]
[tex]\tt{2 \times \dfrac{22}{\cancel{7}} \times \cancel{14}}[/tex]

Consider right triangle
Answer:

Step-by-step explanation:
Find the values of x and y in the diagram.
Step-by-step explanation:
the triangle URT is an Equilateral triangle so all angles are equal to 60°
and the full triangle UTS is a right angle .
5y= 90-60= 30°
y= 6
and since the triangle RST is an Isosceles triangle
so the angle RST and RTS are equal .
in this case =30° .
[tex] \sin(30) = \frac{x - 7}{11 + x - 7 } \\ \sin(30) = \frac{x - 7}{x + 4} \\ 0.5 = \frac{x - 7}{x + 4} \\ 0.5(x + 4) = (x - 7) \\ 0.5x + 2 = x - 7 \\ 0.5x = 9 \\ x = 18[/tex]

Answer:
1. [tex]4x + 5y \leq 60[/tex]
2. 15
3. 12
4. No, because if you put those values into the inequality you get
4 * 9 + 5 * 5 [tex]\leq[/tex] 60 --> [tex]36 + 25 \leq 60[/tex] --> [tex]61 \leq 60[/tex] which is not true.
Step-by-step explanation:
1. if a car costs $4, the total cost of cars is 4x
if a doll costs $5, the total cost of dolls is 5y
you have at most $60 to spend, so the amount you spend has to be less than or equal to 60.
The inequality would be [tex]4x + 5y \leq 60[/tex].
2. At the x-intercept y would be 0, so
4x + 5(0) = 60
4x = 60
x = 15
3. At the y-intercept, x would be 0, so
4(0) + 5y = 60
5y = 60
y = 12

Line segments AC and BD intersect at E. AED=134. What is the measure of CED
Help me fast plssssss
Answer:134
Step-by-step explanation:
The measure of CED is 46°. The correct option is C. 46°
Calculating the measure of angles on a straight lineFrom the question, we are to calculate the measure of angle CED
From the given diagram, we can write that
∠AED + ∠CED = 180° (Sum of angles on a straight line)
From the given information,
∠AED = 134°
Thus,
134° + ∠CED = 180°
∠CED = 180° - 134°
∠CED = 46°
Hence, the measure of CED is 46°. The correct option is C. 46°

Answer:
Step-by-step explanation:
4x-2 +3x+7 = 180
7x + 5 = 180
7x = 175
x = 25
3(25) + 7 = 82
Answer:
82 (degrees)
Step-by-step explanation:
4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25
This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.
3(25) +7=82 which is equal to f
f=82

Michelle is playing a number guessing game where you must guess the two numbers she is thinking about and gives two hints. The first hint is that the sum of two numbers is 50. The second hint is the first number is 43 less than twice the second number. What are the two numbers?
Answer:
The two numbers are a = 57 and b = -7
Step-by-step explanation:
Let's write the first sentence into an equation.
A) The sum of two numbers is 50
[tex]a+b=50[/tex] (1)
B)The first number is 43 less than twice the second number.
[tex]a=43-2b[/tex] (2)
Now, we just need to solve the system of equations (1) and (2)
Let's put (2) into the (1)
[tex]43-2b+b=50[/tex]
[tex]43-b=50[/tex]
[tex]b=43-50[/tex]
[tex]b=-7[/tex]
Using this value in (1) we can find a
[tex]a-7=50[/tex]
[tex]a=57[/tex]
Therefore, the two numbers are a = 57 and b = -7
I hope it helps you!

2. Flying to Kampala with a tailwind a plane averaged 158 km/h . On the return trip the plane only averaged 112 km/h while flying back into the same wind. Find the speed of the wind and the speed of the plane in still air.
Help please
Answer:
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h
Step-by-step explanation:
Given that:
Speed of plane with the wind = 158km/h
Speed of plane against the wind = 112km/h
Let,
x be the speed of plane
y be the speed of wind
According to given statement;
x+y = 158 Eqn 1
x-y = 112 Eqn 2
Adding Eqn 1 and 2
[tex]x+y+x-y=158+112\\2x = 170\\\frac{2x}{2}=\frac{270}{2}\\x=135[/tex]
Putting x = 135 in Eqn 1
135+y = 158
y = 158-135
y = 23
Hence,
Speed of plane in still air = 135 km/h
Speed of wind = 23 km/h

A cylinder has a radius of 7 inches and a height of 13 in. What is the volume
of the cylinder?
Answer:
2,637.18 [tex]in^{3}[/tex]
Step-by-step explanation:
The formula for finding the volume of a cylinder is....
V = π [tex]r^{2}h[/tex]
π = 3.14
Radius = 7
Height = 13
Now that we have what we need, we can substitute the numbers into the equations to get our volume
V = π [tex]r^{2}h[/tex]
V = 3.14 * [tex]7^{2}[/tex] * 13
V = 3.14 * 49 * 13
V = 202.86 * 13
V = 2,637.18
The volume of the cylinder is 2,637.18 [tex]in^{3}[/tex]
