The weight of mr nazeer is 7 times that of his son. What's the ratio of their weights?
Answer:
7:1Step-by-step explanation:
Let the weight of mr nazeer be x
Let the weight of his son be y
If the weight of mr nazeer is 7 times that of his son, then x = 7y
To get the ratio of their weight:
Ratio = weight of father/weight of son
Ratio = 7y/y
Ratio = 7/1
Ratio = 7:1
Hence the ratio of their weights is 7:1

1. A frame is 9 in wide and 6 in tall. If it is reduced to a width of 3 in then how
tall will it be?
Answer:
18 units tall
Step-by-step explanation:
As the frame is 9x6, and the width divides by 3, the height should multiply by 3. In this case, 6x3=18, so the height is 18 units. Hope it helps!

Las bacterias son seres vivos minúsculos que se reproducen dividiéndose por la mitad cada
cierto tiempo. Suponemos una bacteria que se divide cada minuto. En ese caso, después de
dos minutos tendríamos cuatro bacterias, a los tres minutos ocho bacterias y así
sucesivamente. Con ayuda de la escena contesta en tu cuaderno a las siguientes preguntas:
a.- ¿Cuántas bacterias habrá a las dos horas?
b.- Averigua cuánto tiempo hará falta para que haya 33.554. 432 bacterias.
Answer:
a) Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.
b) La población de bacterias será de 33554432 en 25 minutos.
Step-by-step explanation:
a) De acuerdo con el enunciado, podemos apreciar una progresión geométrica, la cual está definida como:
[tex]n = n_{o}\cdot r^{t}[/tex] (Eq. 1)
Donde:
[tex]n_{o}[/tex] - Población inicial de bacterias, adimensional.
[tex]n[/tex] - Población actual de bacterias, adimensional.
[tex]r[/tex] - Tasa de reproducción de la población, adimensional.
[tex]t[/tex] - Tiempo, medido en minutos.
Si sabemos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]t = 120\,min[/tex], entonces la población actual de las bacterias:
[tex]n = 1\cdot 2^{120\,min}[/tex]
[tex]n = 1.329\times 10^{36}\,bacterias[/tex]
Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.
b) Si empleamos (Eq. 1) y asumimos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]n = 33554432[/tex], entonces despejamos [tex]t[/tex] de la fórmula resultante:
[tex]1\cdot 2^{t} = 33554432[/tex]
[tex]2^{t} = 33554432[/tex]
[tex]\log_{2} 2^{t} = \log_{2} 33554432[/tex]
[tex]t = \log_{2} 33554432[/tex]
[tex]t = 25\,min[/tex]
La población de bacterias será de 33554432 en 25 minutos.

the ratio of students who walked home from school to the students who ride the bus home is 2.7. The number of the bus riders is how many times the number of students who walk home?
Answer:
3.5
Step-by-step explanation:
If there are 9 students total and the ratio is 2:7 for walk home to ride bus then the answer would you would divide 2 from 7 which can be written as 7/2 then you would get your answer. Plus if the question says how many times the number... that means division:).

Question 1: A researcher wants to know about the average salary of all General Motors workers. The data can only be collected as whole US dollars. This data can be considered: * qualitative nominal qualitative ordinal quantitative discrete quantitative continuous Question 2: A researcher pla
Answer:
Quantitative Discrete
Step-by-step explanation:
The data about the average salary of all general motor workers cooled ONLY as WHOLE U. S DOLLARS
Firstly, data involving worker's salary are best expressed in figure, hence making such data numerical in nature. Numerical variables are quantitative data as it allows for numerical computation and analysis such as addition, subtraction, mean of the data values and so on.
Secondly, since these data has been strictly restricted to be expressed in whole numbers, this makes the range of the data collected finite and hence countable. This properties ensure that the quantitative data (average salary) is discrete in nature.

When converting a proper fraction to a decimal is the answer less than or greater than 1
Answer:
Proper and Improper Fractions. Mathematicians use three categories to describe fractions: proper, improper, and mixed. Fractions that are greater than 0 but less than 1 are called proper fractions. In proper fractions, the numerator is less than the denominator.
Step-by-step explanation:
Tell whether the given number is a solution of each question. ( Must show work for credit)
1. 9 = 2a + 3; 3
2. 5n - (-30) = 5; 7
3. 4.4r - 2.8 = 1.6; 1
Answer/Step-by-step explanation:
1. [tex] 9 = 2a + 3 [/tex] ; 3
Let's solve for a.
[tex] 9 - 3 = 2a [/tex] (subtraction property of equality)
[tex] 6 = 2a [/tex]
[tex] \frac{6}{2} = a [/tex] (division property of equality)
[tex] 3 = a [/tex]
[tex] a = 3 [/tex]
Therefore, 3 is a solution to 9 = 2a + 3
2. [tex] 5n - (-30) = 5 [/tex] ; 7
[tex] 5n + 30 = 5 [/tex] (- × - = +)
[tex] 5n = 5 - 30 [/tex] (Subtraction property of equality)
[tex] 5n = -25 [/tex]
[tex] \frac{5n}{5} = \frac{-25}{5} [/tex] (division property of equality)
[tex] n = -5 [/tex]
Therefore, 7 is not a solution of [tex] 5n - (-30) = 5 [/tex]
3. [tex] 4.4r - 2.8 = 1.6 [/tex] ; 1
[tex] 4.4r = 1.6 + 2.8 [/tex]
[tex] 4.4r = 4.4 [/tex]
[tex] \frac{4.4r}{4.4} = \frac{4.4}{4.4} [/tex]
[tex] r = 1 [/tex]
Therefore, 1 is a solution of [tex] 4.4r - 2.8 = 1.6 [/tex].
h(x) = x + 1 k(x) = x - 2 (h + k)(2) =
[tex]h(x) = x + 1[/tex]
[tex]k(x) = x - 2[/tex]
_________________________________
[tex](h + k)(x) = h(x) + k(x)[/tex]
[tex](h + k)(x) = (x + 1) + (x - 2) \\ [/tex]
[tex](h + k)(x) = x + 1 + x - 2[/tex]
[tex](h + k)(x) = 2x - 1[/tex]
[tex](h + k)(2) = 2(2) - 1[/tex]
[tex](h + k)(2) = 4 - 1[/tex]
[tex](h + k)(2) = 3[/tex]

SAS (side angle side)
Step-by-step explanation:
This rule states that if 2 sides are equal and the angle between the sides are also equal, then the 2 triangles must be congruent.
Therefore, the answer must be SAS (side angle side).
Answer:
Hello!!! Princess Sakura here ^^

The answer is choice A. SAS
You can see that side QR is congruent to side XY and side RS is congruent to side WX, then angle R is congruent to angle X. So it's a SAS
Fatima has a student loan the loan amount is 15,000 for 10 years her interest rate is 8.25% how much will Fatima pay in interest
Answer:
8212.67
Step-by-step explanation:
From the data given in the question;
Amount = 15000
Principal = ?
rate = 8.25%
time = 10 years
From;
A =P(1 + r)^n
15000 = P(1 + 0.0825)^10
P= 15000/2.21
P= 6787.33
but
Interest = Amount - Principal
Interest = 15000 - 6787.33
interest = 8212.67
Five different companies (G, J, S, O, U) compete each year to be the sole supplier of relays to a major automobile manufacturer. Supplier G J S O U probability .15 .04 .01 .55 .25 Given that suppliers O and U are both ultimately not chosen, what is the probability that supplier S will be chosen
Answer:
The probability is [tex]P(S | (O ,U)' ) = 0.05[/tex]
Step-by-step explanation:
From the question we are told that
The probability of each company to be chosen is
Supplier G J S O U
Probability 0.15 0.04 0.01 0.55 0.25
Generally the probability that company G , J , S are chosen is
[tex]P(G , J , S ) = 0.15 + 0.04 + 0.01[/tex]
=> [tex]P(G , J , S ) = 0.20[/tex]
Generally the probability that company O, U are chosen is
[tex]P(O, U ) = 0.55+ 0.25[/tex]
=> [tex]P(O, U ) = 0.80[/tex]
Generally the probability that supplier S will be chosen given that suppliers O and U are both ultimately not chosen is mathematically represented as
[tex]P(S | (O ,U)' ) = \frac{ P(S \ n \ (O , U)' )}{ P((O, U)')}[/tex]
[tex]P((O, U)' = 1 - P(O , U)[/tex]
[tex]P((O, U)' = 1 - 0.8[/tex]
[tex]P((O, U)' =0.2[/tex]
And
[tex]P(S \ n \ (O , U)' ) = P(S) = 0.01[/tex]
=> [tex]P(S | (O ,U)' ) = \frac{ 0.01 }{ 0.2}[/tex]
=> [tex]P(S | (O ,U)' ) = 0.05[/tex]

A cash register contains q quarters. Write an algebraic expression that represents the total amount of money (in dollars).
Answer:
0.25q
Step-by-step explanation:
A cash register is a machine used in small business that sums, display and records the total amount made by each sale. A cash register also has a drawer which is used to store money.
A quarter is a coin in the United States which is 25 cents.
Converting 25 cents to dollars:
100 cents = $1
25 cents = 25 cents × $1 / 100 cent = $0.25
The total amount of money registered = number of quarters × $0.25
The total amount of money registered = q × $0.25 = 0.25q
