Answer:
Width is 5 cm
Step-by-step explanation:
Since we know that the width is 25 meters, and the scale we are using is 5 meters = 1 cm, we can divide 25 by 5 to find the scaled measurement.
25/5 = 5cm

Step-by-step explanation:
A used bookstore sells hardback books and paperback books.A hardback book costs $11, including tax.A paperback book costs $5, including tax.Jamal bought 3 more paperback books than hardback books.Jamal spent $47. How many paperback books did Jamal buy? A.2 B.3 C.4 D.5
Answer:
D.5
Step-by-step explanation:
You can write the following equations from the information given:
y=x+3 (1)
11x+5y=47 (2)
x is the number of hardback books
y is the number of paperback books
You can replace (1) in (2):
11x+5(x+3)=47
11x+5x+15=47
16x=47-15
16x=32
x=32/16
x=2
Then, you can replace the value of x in (1) to find the value of y:
y=2+3
y=5
According to this, the answer is that Jamal bought 5 paperback books.

The volume of cube 4x².
What is Volume?Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.
We have,
Edges of cube as = 4 , x and x.
So, volume of cube

HURRY PLEASE When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6? The ratios are equivalent to 5:6. The ratios are equivalent to 6:5. The ratios are greater than 5:6, as the factors become greater. The ratios are greater than 6:5, as the factors become greater.
Answer:
The ratios are equivalent.
Step-by-step explanation:
If you multiply both 5 and 6, the ratio stays the same.
5:6 = 10:12 = 15:18 = 20:24 etc.
You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.
24/20 = 1.2
15/18 = 1.2
10/12 = 1.2
6/5 = 1.2

solve for the missing missing variable C=2πr; C=18.84, π=3.14
Answer:
The missing variable r = 3
Step-by-step explanation:
C = 2πr
Where,
C = 18.84
π = 3.14
r= ?
The missing variable is r
C = 2πr
Making r the subject
r = C / 2π
= 18.84 / 2*3,14
= 18.84 / 6.28
= 3
r = 3
The missing variable r = 3
Check:
C = 2πr
18.84 = 2*3.14*3
18.84 = 18.84

Simplifying the top:
(2* a^3 * b^5)^2 * (6ab)
4* a^6 *b^10 * (6ab)
24 *a^7 * b^11
so we have
(24 *a^7 * b^11) / (-3* a^5 *b)
immediately we can simplify 24 and -3
(-8 *a^7 * b^11) / ( a^5 *b)
a^7 and a^5 can cancel into just a^2
(-8 *a^2 * b^11) / (b)
b^11 and b cancels to b^10
-8 *a^2 * b^10
so that is your answer:

To get rid of the coefficient of w, 3/2 in this case, we must divide the entire equation by 3/2, which is the equivalent of multiplying the entire equation by 2/3. Doing this, we get:

7x-(6x-1)=2. What is the answer?
Answer:
x=1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−(6x−1)=2
7x+−1(6x−1)=2(Distribute the Negative Sign)
7x+−1(6x)+(−1)(−1)=2
7x+−6x+1=2
(7x+−6x)+(1)=2(Combine Like Terms)
x+1=2
x+1=2
Step 2: Subtract 1 from both sides.
x+1−1=2−1
x=1

9:25 y 33:41:38 a que unidades de tiempo se refieren?
Answer:
Se refieren a las unidades de tiempo del sistema sexagesimal
9:25 son 9 minutos y 25 segundos
33:41:38 son 33 horas, 41 minutos y 38 segundos.
Step-by-step explanation:
El sistema sexagesimal se utiliza para medir tiempos y ángulos.
El tiempo se mide en horas,minutos y segundos
En cambio, los ángulos se miden en grados,minutos y segundos.
Los dos puntos '':'' sirven para separar las unidades.
La base de este sistema es el número 60 :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 hora
Eso en cuanto a tiempo
En cuanto a grados :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 grado
Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos
Entonces, 9:25 son 9 minutos y 25 segundos
Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).
Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.
Mrs. Bell has an interest rate of 4.175% on her house. Mr. Bentley has an interest rate of 4.25% on his house. Which explains who has the lower interest rate?
Answer: Mrs Bell
Step-by-step explanation:
From the question, we are informed that Mrs. Bell has an interest rate of 4.175% = 0.04175 on her house and Mr. Bentley has an interest rate of 4.25% = 0.0425 on his house.
The person who has the lower interest is Mrs Bell. This is because 4.25% is higher than Mrs Bell's interest of 4.175%
Answer:
The answer is D
Step-by-step explanation:
Mrs bell has the lower interest rate because both decimals have a 4 in the ones place, and 1 tenth is less than 2 tenths.
