Answer:
Circumference: C = 7.5π m. This is approximately 23.56 m
Total fencing cost: $215.76
Step-by-step explanation:
Ashton walks along the diameter of the garden, which is 7.5 m.
The circumference formula C = πd yields C = 7.5π m. This is approximately 23.56 m, which we must round up to 24 m, and which calls for 24 - 1 m pieces at $8.99 each.
The desired fencing would cost (24 m)($8.99/m), or $215.76
If two side of a right angle triangle is 25cm and 15cm what is the length of the unknown side
Answer:
29.2 cm
Step-by-step explanation:
The two leg lengths are 15 and 25 cm and we are to find the length of the hypotenuse. The Pythagorean Theorem applies here because this is a right triangle.
a^2 + b^2 = c^2 becomes 15^2 + 25^2 = 225 + 625 = 850
The hypotenuse length is thus √850 ≈ 29.2 cm
Calcula el área de un rombo cuya diagonal mayor mide 10 cm y cuya diagonal menor es la mitad de la mayor.
Respuesta:
25 cm²
Explicación paso a paso:
El área A de un rombo tiene:
A = pq / 2
Donde pyq son las diagonales
Tomando p como la diagonal más grande = 10 cm
Diagonal más pequeña, q = 1/2 * 10 = 5cm
Por lo tanto, el área del rombo es:
A = (10 * 5) / 2
A = 50/2
A = 25 cm²
Sixteen added to a number is equal to forty. Find the number.
Answer:
The number is 24
Step-by-step explanation:
Let x = number
Add 16 to the number
x+16
Is equal to 40
x+16 = 40
Subtract 16 from each side
x+16-16 = 40-16
x = 24

Find the gradient of the line segment between the points (-3,2) and (4,4).
Answer:
slope = [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (4, 4)
m = [tex]\frac{4-2}{4-(-3)}[/tex] = [tex]\frac{2}{4+3}[/tex] = [tex]\frac{2}{7}[/tex]
Answer:

plz help me it worth 50% of my grade tell wethere it’s proportional of not
Answer:
2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional.
Step-by-step explanation:
Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line.
Number 3 does not go through the origin, so number 3 is also not proportional.
Number 5 is proportional since when you divide y by x, it is always 7.
Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.

find the measure of angle TFM
Answer:
130°
Step-by-step explanation:
angle TFM + angle MFD = 180° (being a linear pair)
or, 4m + 142° +2m + 56°= 180°
or, 6m= 180°- 198°
or, m= -18°/6
so, m= -3°
now, angle TFM = 4m +142°= -12°+142°= 130°

What is an equation of the line that passes through the point (-8,0) and is parallel to the line x+2y=14?
Answer:
y=-1/2x-4
Step-by-step explanation:
Hi there!
We're given the equation x+2y=14 and we want to find a line that is parallel to it and passes through (-8,0)
Parallel lines have the same slopes, but different y intercepts.
So let's find the slope of x+2y=14
we do this by converting x+2y=14 from standard form (ax+by=c where a, b, and c are integers) to slope-intercept form (y=mx+b, where m is the slope and b is the y intercept).
for x+2y=14, to convert to slope-intercept form, start by subtracting x from both sides
2y=-x+14
divide both sides by 2
y=-1/2x+7
so the slope of x+2y=14 is -1/2
The slope of the new line (the one parallel to x+2y=14 and passes through (-8,0) will also have a slope of -1/2).
Here's the equation of that line so far:
y=-1/2x+b
we need to find b (y intercept)
as the equation will pass through (-8,0), we can use it to solve for b
substitute -8 as x and 0 as y
0=-1/2(-8)+b
multiply
0=4+b
subtract 4 from both sides
-4=b
substitute into the equation
y=-1/2x-4

A rectangle if formed by placing two identical squares side by side. The perimeter of the rectangle is 6 cm. What is the total area of the squares.
Answer:
2 cm²
Step-by-step explanation:
Perimeter of a rectangle = perimeter of a square + perimeter of a square
2 congruent squares, side by side
The perimeter of the two squares = 6*sidelength.
Perimeter of a rectangle = 6 cm
The perimeter of the two squares = 6 * length
= 6l
Perimeter of a rectangle = The perimeter of the two squares
6 = 6l
l = 6/6
l = 1
Length = 1 cm
What is the total area of the squares.
Area of a square = lenght²
Area of two squares = 2(length ²)
= 2(1²)
= 2(1)
= 2 cm²
Joey is running an experiment with a mass on a spring. Joey models the height of the mass above the table he is working on using the equation h(t)=6.85cos(3.42t)+9, where the height is in inches and the time, t, is in seconds since he let the mass free. How many seconds, to the nearest tenth, will it take for the mass to return to its original position?
Answer: 1.8 s
Step-by-step explanation:
Given
The height of the spring mass system above the table is given by
[tex]h(t)=6.85\cos (3.42t)+9[/tex]
The mass is performing S.H.M with frequency [tex]\omega =3.42[/tex]
and [tex]\omega T=2\pi[/tex]
[tex]\therefore T=\dfrac{2\pi }{\omega}[/tex]
time when mass returns to its original position
[tex]T=\dfrac{2\pi }{3.42}\\\\T=1.8\ s[/tex]
The number of seconds, to the nearest tenth, will it take for the mass to return to its original position is 1.8 seconds.
Calculation of the time in seconds:Since the equation h(t)=6.85cos(3.42t)+9, where the height is in inches and the time, t, is in seconds
So here the time should be
[tex]= 2\pi \div 3.42\\\\= 2\times 3.14\div 3.42[/tex]
= 1.8 seconds
Therefore, The number of seconds, to the nearest tenth, will it take for the mass to return to its original position is 1.8 seconds.

Step-by-step explanation:
Area of a rectangle is
A = l*w
A = 25.8*14.5
A =374.1 m^2
Answer:
Area of rectangle is 374.1 m ²
Step-by-step explanation:
Given That :-Length of rectangle = 25.8 mBreadth of rectangle = 14.5 mTo Find :- Area of rectangleFormula Used :-Area of rectangle = Length × Breadth
Solution : -Using Formula
Area of rectangle = Length × Breadth
substitute the values.

Pedro sale en bicicleta a velocidad constante desde La Romana hacia Santo Domingo a las 10 A.M. Una hora mas tarde se encuentra a 109 km de La Romana sabiendo que la distancia de Santo Domingo a La Romana es de 130 km
V: velocidad
T: tiempo
D: distancia
V= D/T
Answer:
Pedro está circulando a 21 km por hora, y llegará a destino a las 16:12 hs.
Step-by-step explanation:
Dado que Pedro sale en bicicleta a velocidad constante desde La Romana hacia Santo Domingo a las 10 A.M, y una hora mas tarde se encuentra a 109 km de La Romana, sabiendo que la distancia de Santo Domingo a La Romana es de 130 km, para determinar la velocidad a la cual Pedro está circulando y a qué hora llegará a destino se debe realizar el siguiente cálculo:
130 - 109 = 21 km por hora
130 / 21 = 6.19
1 = 60
0.19 = X
0.19 x 60 = 11.4
Por lo tanto, Pedro está circulando a 21 km por hora, y llegará a destino a las 16:12 hs.
