Answer:
a) x = 8
b) x = 18
Step-by-step explanation:
Given that
9 : x : : 54 : 48
This may be rewritten as
9/x = 54/48
cross multiply
9 * 48 = 54 * x
Divide both sides by 54
x = 9 * 48/54
= 8
b Given that 2, 6, x are in continued proportion then
2/6 = 6/x
2 * x = 6 * 6
x = 36/2
= 18

Autos de F 1. En un circuito de Australia, Hamilton hizo el récord de vuelta. Si lo normal a 240km/h para completar el circuito de 6000 metros son 2 minutos ¿Qué tiempo debió hacer para recorrer el record de vuelta Y a qué velocidad promedio lo hizo?
Answer:
Tenía que hacerlo en menos de 2 minutos a más de 240 km/h
Step-by-step explanation:
La velocidad normal dada para completar el circuito de 6.000 metros = 240 km/h
El tiempo normal que se tarda en completar el circuito de 6000 metros = 2 minutos
Dado que Hamilton estableció el récord de vuelta, el tiempo que tuvo que hacer para recorrer el récord de vuelta es de 6000 metros en menos de 2 minutos
La velocidad media con la que lo hizo es de más de 240 km/h.

A rectangle has a length of 6 inches and a width of 8 inches. A square with a side length of 3 was cut out of it. What is the area of the remaining paper
Answer: 39 inch²
Step-by-step explanation:
The rectangle's area was:
= Length * Width
= 6 * 8
= 48 inches²
The square's area is:
= Length * width
= 3 * 3
= 9 inches²
The square was cut out of the rectangle which means the area of the square should be deducted from the rectangle to find out the remaining area.
= 48 - 9
= 39 inch²

Answer:
55° is x
Step-by-step explanation:
Angle sum property of triangle = 180°
180 - 70 = 110
As it is an isosceles triangle, two sides and of course angles will be same.
So, 110 ÷ 2 = 55.
So, the two remaining angles will be 55°

If the diameter of the tennis ball is 2.6 inches, what is its circumference, in inches?
Answer:
8.164
Step-by-step explanation:
The circumference of the ball is 8.164 inches.
Calculation of the circumference:
Since the diameter of the tennis ball is 2.6 inches
So here the radius should be half i.e. 1.3 inches
Now we know that
Circumference = [tex]2\pi r\\\\[/tex]
= 2(3.14)(1.3)
= 8.164 inches
Therefore, we can conclude that The circumference of the ball is 8.164 inches.

For square ABCD, if m∠ACB = (8x – 27)°, find the value of x.
Answer:
x=9
Step-by-step explanation:
Since ABCD is a square, we know that AC bisects ∠BCD(=90), and therefore ∠ACB=45.
8x-27=45
8x=72
x=9
Answer:
x = 9°
Step-by-step explanation:
∠ACB = 45° because line AC bisects ∠BCD which is 90° (because square).
8x - 27° = 45°
add 27° to each side:
8x = 72°
divide both sides by 8:
x = 9°
Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth.
Answer:
[tex]x = 9.9[/tex]
[tex]y= 7[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x and y
Considering [tex]\theta = 45[/tex]
From the attached triangle, length x is the hypotenuse and length y is the adjacent
Solving for x
[tex]Sin\theta = \frac{Opp}{Hyp}[/tex]
[tex]Sin\theta = \frac{7}{x}[/tex]
So, we have:
[tex]Sin45 = \frac{7}{x}[/tex]
[tex]x= \frac{7}{Sin45 }[/tex]
[tex]x = \frac{7}{0.7071}[/tex]
[tex]x = 9.9[/tex]
Solving for y
Considering [tex]\theta = 45[/tex]
[tex]Tin\theta = \frac{Opp}{Adj}[/tex]
So, we have:
[tex]Tin45= \frac{7}{y}[/tex]
[tex]y= \frac{7}{Tan45}[/tex]
[tex]y= \frac{7}{1}[/tex]
[tex]y= 7[/tex]
The value of x and y is 9.9 and 7.
Calculation of the value:Since theta is 45 degrees
So, we know that
Sin theta = opp/hyp
Sin theta = 7 /x
x = 7 / 0.7071
= 9.9
Now the value of Y should be
Tin theta = opp/hyp
y = 7 \tan 45
= 7 /1
= 7
Therefore, we can conclude that The value of x and y is 9.9 and 7.

Find the volume of the pyramid, given its slant height. Round them to the nearest tenth please.
Can you help me? I tried but I did not understand and thank you
9514 1404 393
Answer:
4. 1.3 cm³
5. 621.2 mm³
6. 116.5 m³
Step-by-step explanation:
The height to the peak of the pyramid is one side of the right triangle that has its hypotenuse equal to the slant height, and one leg equal to half the base side length. The Pythagorean theorem is used to find the height from the slant height (s) and the base length (b):
h = √(s² -(b/2)²)
The volume is found from the formula ...
V = (1/3)b²h
where b is the base length and h is the height found using the previous formula.

What is the Value of X in the triange
Answer:
x = 65
Step-by-step explanation:
The sum of the angles of a triangle add to 180
25+ 2x+25 = 180
Combine like terms
50+2x = 180
Subtract 50 from each side
2x = 180-50
2x =130
Divide by 2
2x/2 =130/2
x =65

Step-by-step explanation:
Answer:
x = 122°
Step-by-step explanation:
since it is a right triangle, the sum of the other 2 interior angles = 90°
the angle opposite x = 90° - 32° = 58°
58° and angle x are supplementary angles. Their sum is 180°.
180° - 58° = 122°

Find the missing values in the ratio table. Then write equivalent ratios.
5:3 ?:12 10/3:? ?:5
Answer:

3 12 12/3 5
Step-by-step explanation:
The missing values in the ratio table will be;
Pies 5 20 10/3 25/3
Cakes 3 12 2 5
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
The ratio table is;
Pies 5 x 10/3 z
Cakes 3 12 y 5
Now,
Since, The ratios are equivalent to each other.
Thus, We can solve to find the value of x, y and z as;
⇒ 5 : 3 = x : 12
⇒ 5/3 = x/12
Multiply by 12;
⇒ 5 × 12 / 3 = x
⇒ 20 = x
And, 5 : 3 = 10/3 : y
⇒ 5/3 = 10/ (3× y)
⇒ 5/3 = 10/3y
Multiply by 3;
⇒ 5 = 10/y
⇒ y = 10/5
⇒ y = 2
And, 5 : 3 = z : 5
⇒ 5/3 = z/5
Multiply by 5;
⇒ 25/3 = z
⇒ z = 25/3
Therefore, The missing values in the ratio table will be;
Pies 5 20 10/3 25/3
Cakes 3 12 2 5

The admission fee at a John Hay basketball game is $1.50 for students and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected.
How many of each type of ticket did they sell?
Student:
and
Adult
Answer:
See below, please!
Step-by-step explanation:
We can set up a system of equations to model this problem. Let's consider the student's ticket as x, and y for the adult ticket.
So since the student ticket is $1.50, and adult is $4, we can set up the following equation: [tex]1.5x+4y=5050[/tex], since they collected $5050 total.
We can set up another equation modeling the number of people who came to the game. This would be x+y=2200.
Solve this, and we get x= 1500 and y=700. So, they sold 1500 student tickets and 700 adult tickets.

143 inches = ________ a) 14 feet 3 inches b) 13 feet 9 inches c) 12 feet 2 inches d) 11 feet 11 inches
Answer:
D. 11 feet 11 inches
1 foot= 12 inches
143/ 12 = 11 11/12
Answer:
D) 11 feet and 11 inches
Step-by-step explanation:
First we know that there is 12 inches in a foot. So let's start with a.
14 inches x 12 inches (one foot) is 168 inches (so it's not this one:)
13 inches x 12 inches is 156 inches (It's not this one either)
12 inches x 12 inches is 144 inches (not this one)
11 inches x 12 inches is 132 inches (so it could be this one, let's add the remaining inches).
132 + 11 inches = 143 inches.
(Notice I didn't add the remaining inches on A, B, or C because the number of inches was already too much. I did on D because the number of inches was below the given number of 143.
