Answer:
a. 5 n/p o 1 p/ 5n
b. 1720 autos asia/3060 autos, o 1320 autos USA/3060 autos
Step-by-step explanation:
Se entiende como razón a la fracción que compara dos elementos entre sí.
Por ejemplo en una clase de 24 alumnos donde 15 son mujeres y 9 son varones, podemos decir que:
- Por cada 15 mujeres hay 9 varones 9/15
- Por cada 9 varones hay 15 mujeres, 15/9
Para el ejercicio a. nos cuentan que 1 pelota es utilizada cada 5 niños, por lo que la razón la podemos escribir como 1/5, 1 pelota cada 5 o directamente 5, ya que por cada 5 alumnos, tenemos 1 pelota.
El ejercicio b es más fácil: ya tenemos el total de autos, 3060. Entonces:
- Cada 3060 autos, 1720 son asiáticos
- Cada 3060 autos, 1320, son americanos
Jackson's rectangular bedroom has an area of 90 sq ft. The area of his bedroom is 9 times that of his rectangular closet. If the closet is 2 ft wide, what is it's length?
Answer:
5 feet
Step-by-step explanation:
Since Jackson's bedroom is a rectangle, it has dimensions of length times width. Suppose the length is l and the width is w.
The area of a rectangle is given by A = lw, where l is the length and w is the width. Here, we know the area is 90, so:
lw = 90
We also know that this area of 90 square feet is 9 times that of the closet, so suppose the area of the closet is c. Then:
9c = 90
Divide by 9:
c = 90/9 = 10 square feet
So, the area of the closet is 10 square feet. Since the width is 2, we know the length will be:
A = lw
10 = lw
10 = 2 * l
l = 10/2 = 5
The length is thus 5 feet.
~ an aesthetics lover
Answer:
5 ft
Step-by-step explanation:
If his bedroom is 9 times of his closet, then that means you divide the area of his bedroom by 9. So, 90 divided by 9=10. That means the closet has an area of 10 sq. ft. As we all know, the area is the length times width. So if the width is 2 ft, then we need to multiply it by a number so it will equal 10. You can do 10 divided by 2 to find it, which equals 5. That means the length of the closet is 5 sq. ft.

A regular pentagon is shown
The perimeter is 125 cm
Write an equation and solve this
to find the value of x.
Answer: The equation is 5x = 125
Step-by-step explanation:
A pentagon is a five sided figure so all the side lengths must be equal. And to find the perimeter of a pentagon the you will the five equal side lengths.
So assume we don't know the side lengths so we will represent it by x and the side lengths are 5 so we will have five x's and they will add up to 125 and that could be represent by the equation.
x + x + x + x + x = 125
5x = 125
x = 25

Wait times at a dentist's office are typically 21 minutes, with a standard deviation of 2 minutes. What percentage of people should be seen by the doctor between 17 and 25 minutes for this to be considered a normal distribution?
Answer:
95%
Step by step explanation:
z = 17-21 / 2 and z = 25-21/2
z=-2 (2.28%) z=2 (97.72%)
97.72 - 2.28 = 5.44
100% - 5.44% is about equal to 95%

Determine for each x-value whether it is in the domain of f or not
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = [tex]\frac{x}{x-7}[/tex]
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be.
solve
x - 7 = 0 ⇒ x = 7 ← excluded value
Thus
x = - 7 → in domain
x = 0 → in domain
x = 7 → not in domain
Answer:

Which set of integers represents the lengths of the sides of an isosceles triangle? A. {6,6,5} B. {3,4,5} C. {15,5,10} D. {1,1,3}
Answer:
A 6,6,5
Step-by-step explanation:
because an isosceles triangle has two it side equal
The set of integers represents the lengths of the sides of an isosceles triangle is A (6,6,5).
What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle.Properties of an Isosceles Triangle
Here is a list of some properties of isosceles triangles:
In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal.In the isosceles triangle given above, the two angles ∠B and ∠C, opposite to the equal sides AB and AC are equal to each other.The isosceles triangle has three acute angles, meaning that the angles are less than 90°.The sum of three angles of an isosceles triangle is always 180°. Types of Isosceles TrianglesGenerally, isosceles triangles are classified into three different types:
Isosceles acute triangle: An isosceles acute triangle is a triangle in which all three angles are less than 90°, and at least two of its angles are equal in measurement. Isosceles right triangle: The following is an example of a right triangle with two legs (and their corresponding angles) of equal measure. Isosceles obtuse triangle: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.Therefore, set of integers represents the lengths of the sides of an isosceles triangle {6,6,5}.

( 7+x+2) * 7 = ( 6+8) * 6
Combine like terms
(9+x) *7 = 14*6
Distribute
63 +7x = 84
Subtract 63
63 +7x -63 = 84-63
7x =21
Divide by 7
7x/7 = 21/7
x = 3
KM = x+2+7
= 3+2+7
=12
Answer:
[tex]\huge\boxed{KM = 11}[/tex]
Step-by-step explanation:
According to secant - secant theorem:
(MK)(ML) = (MR)(MN)
Where
MK = 7 + x+ 2 = x + 9
ML = 7
MR = 8 + 6 = 14
MN = 6
=> (x+9)(7)= (14)(6)
=> 7x + 63 = 84
Subtracting both sides by 63
=> 7x = 84 - 63
=> 7x = 21
Dividing both sides by 7
=> x = 3
Now,
KM = x + 9
KM = 3 + 9
KM = 11

Answer:
117°
Step-by-step explanation:
Arc ABC (AB + BC) is intercepted by angle D.
Therefore, Arc ABC is 2 × m<D. (Inscribed Angle Theorem)
AB = 91°
m<D = 104°
Let BC = x
Arc ABC = (91° + x)
Thus,
91° + x = 2 × 104°
Solve for x
91 + x = 208
Subtract 91 from both sides
91 + x - 91 = 208 - 91
x = 117
Measure of arc BC = 117°

For answers, please refer to the picture attached
Answer:
I can't give a full answer because I can't see the image whilst giving an answer but I'll try so....
Step-by-step explanation:
Angles in a straight line add to 180° so when you have one of two of them angles are them together and take away from 180°
Angles around a full point add to 360° so add angles together and take away from 360°
On A I think it is you have a 360° angle and have to work out 3 and you have one already done and the opposite angle is the same as that so you basically have two angles then you add them together then take from 360 then divide the answer by two and then that would be the angles for a and x
And for the last one you have been given two angles with a right angle and a right angle equals 90 so add them together and take from 180 to get the missing angle
Hope this helps :)

Answer:
3rd option is correct
Step-by-step explanation:
If the table represents a function, that means that it is proportional. But the value increases and decreases, showing no proportional relationship.
So, the answer could be 1st or 3rd as they tell that the table doesn't represent a function.
1st answer says the table doesn't represent a function because the 2 (y-values) are similar;
Their x-values are different so, this answer is wrong.
3rd answer says that the table doesn't represent a function x-value increases, while y-value increases and decreases;
The statement is correct because it this table doesn't represent a proportional relationship as its y-values are increasing and decreasing while its x-values are only increasing.
So, the 3rd option is correct.

Answer:
x = 5
Step-by-step explanation:
The measure of an arc equals the measure of the central angle that intercepts it.
The measure of an arc intercepted by a diameter is 180 deg.
m(arc)EH = 180
m(arc)EF + m(arc)FG + m(arc)GH = m(arc)EH
10x + 8 + 67 + 11x = 180
21x + 75 = 180
21x = 105
x = 5
a number has 2,5 and 7 as its prime factors. what are the four smallest values it and take
Answer:
70, 140, 280, 350
Step-by-step explanation:
Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.
Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...
So, the four smallest numbers with prime factors of 2, 5, and 7 are ...
70 = 2·5·7
140 = 2²·5·7
280 = 2³·5·7
350 = 2·5²·7
Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes one person \dfrac{2}{3} 3 2 start fraction, 2, divided by, 3, end fraction of a minute to prepare one bag. How many hours will it take Ashley and 444 of her friends to prepare 157515751575 bags of samples?
Answer:
3 1/2 hours
Step-by-step explanation:
This is a problem in units conversion. We want to get from bags to hours by way of minutes per bag. One bag takes an effort of 2/3 person·minute, so we need to divide the total effort by the number of persons and convert minutes to hours.
(1575 bags)×(2/3 person·min/bag)/(5 person)/(60 min/h)
= (1575)(2/3)(1/5)(1/60) h = 3.5
It will take the 5 of them about 3 1/2 hours to prepare 1575 bags.

Solve equations show all steps 1. 2x-10=44+8x 2. 7x-4=20=3x 3. 2(x-3)=-20 4. 15-4x+5=32
Answer:
2x - 10 = 44 + 8x
7x - 4 = 20 =3x
2(x-3) = -20
15 - 4x + 5 = 32
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x-10-(44+8*x)=0
Pull out like factors :
-6x - 54 = -6 • (x + 9)
-6 = 0
Solve : x+9 = 0
Subtract 9 from both sides of the equation :
x = -9
x = -9
