Answer:
24 movies
Step-by-step explanation:
48 is a constant. 2 and 4 are variables. So we write 48+2x=4x to show they are equal after some amount of movies. Isolate to get 4x-2x=48. Simplify to get 2x=48. Divide each side by 2 to get x=24. The answer is 24.

Jim is baking chocolate chip muffins. He has a total of 7 1/3 cups of chocolate chips. If each batch of muffins uses 2/3 of a cup of chocolate chips, enter the most number of batches of muffins Jim can bake
Answer:
16
Step-by-step explanation:
The first step to answering a question like this is to turn it into an improper fraction so 7 1/3=24/3. Then divide the numerator by the denominator so 24 divided by 3=8 so 8=1/3. Their is 2/3 so do 8 times 2 which equals 16
Greta is taking a road trip from Cincinnati to San Francisco. On the first day, she drove 650 miles in 10 hours. On the second day, she got a later start and drove 540 miles in 8 hours. How many miles per hour faster was her average speed the second day?
Answer:
2.5 miles per hour fasterStep-by-step explanation:
Step one:
the first day
distance= 650miles
time taken= 10 hours
speed= distance/time
speed= 650/10
speed= 65miles per hour
Step two:
the second day
distance= 540mile
time taken= 8 hours
speed= distance/time
speed= 540/8
speed= 67.5miles per hour
Step three:
the difference between the two speeds is =67.5-65= 2.5
therefore on the second day, the speed is 2.5 miles per hour faster

A small business borrows $50,000 to get started. Some of the money is borrowed at 9%, some at 7%, and some at 10% simple interest. The total of the annual interest they are charged is $4340, and the amount borrowed at 7% is two times the amount borrowed at 9%. Set up a system of equations to represent the situation, then find the amounts of money (x, y, and z) borrowed at each interest rate.
Answer: Amount borrowed at 9% = 9,428.57
Amount borrowed at 7% = $18,857.14
Amount borrowed at 10% = $ 21,714.29
Step-by-step explanation:
Formula for simple interest :
I = PRT,
P= Principal, R =rate , T= time
Let x = amount borrowed at 9%.
y = amount borrowed at 7%.
z = amount borrowed at 10%.
i.e. x+y+z= 50000 (i) [Given : amount invested = 50000]
Interest on x = x (0.09)(1) [as P=x, T=1 year, r= 0.09]
= 0.09x
Similarly
Interest on y = y(0.07)(1) = 0.07y
Interest on z = z(0.1)(1)=0.1z
Total interest = 0.09x+0.07y+0.1z = 4340 (ii)
Also, y=2x [given] (iii)
Put y=2x in (i) and (ii), we get
x+2x+z= 50000 ⇒ 3x+z=50000 (iv)
0.09x+0.07(2x)+0.1z=4340 ⇒ 0.09x+0.14x+0.1z=4340
⇒ 0.23x+0.1z=4340 (v)
Multiply 10 on both sides of (v)
2.3x+z=43400 (vi)
Eliminate (vi) from (v)
0.7x=6600
⇒ x= 9,428.57
From (iii), y= 2(9428.57) =18,857.14
From (vi),
2.3(9428.57)+z=43400
⇒ 21685.71+z=43400
⇒ z= 43400-21685.71
⇒ z=21714.29
Hence, Amount borrowed at 9% = 9,428.57
Amount borrowed at 7% = $18,857.14
Amount borrowed at 10% = $ 21,714.29

Encik Ahmad builds a rectangular shaped garden
measuring 85 m long and 30 m wide. He divides the
garden into square plots to plant a variety of flowers.
Find the number of square plots that can be built if he
only wants three different square sizes.
Answer:he should build them 25x10
Step-by-step explanation:
Encik Ahmad can build 10 square plots with three different sizes.
What is Rectangle?Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.
Length of the rectangular plot = 85 m
Width of the rectangular plot = 30 m
We have to find the number of square plots Encik Ahmad can built of three different sizes.
For that first we take a 45 m length of the plot.
Divide it to three equal lengths. We get three lengths with each 15 m length.
Along the width also, divide into two equal width, each having a width of 15 m.
Each 15 m length, we will get two square plots.
Along 45 m length, we get 3 × 2 = 6 square plots.
The remaining rectangle has length 40 m and width 30 m.
Divide this length as 30 m and 10 m.
So we get a square of dimension 30 m.
Remaining is a rectangle whose remaining length is 10 m and width 30 m.
Along the width, divide into three equal widths, each 10 m.
So there we get three square plots with side length 10 m.
So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.
Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.

Roman solved the equation 5 a + 2 b = 10 for a. His steps are shown below.
1. Subtract 2b: 5 a + 2 b minus 2 b = 10 minus 2 b. 5 a = 10 minus 2 b.
2. Multiply by 5: a = 50 minus 10 b.

Choose the best explanation for why the graph shown is a line of best fit.
The graph shows a line of best fit because the points fit around the line.
The graph shows a line of best fit because there is a straight line.
The graph shows a line of best fit because the association is zero.
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Answer:
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Step-by-step explanation:
The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have a line of best fit shown in the picture.
As we know if the slope of the line is positive then the correlation will be positive.
From the line of best fit:
Because the points are evenly spaced above and below the line, the graph displays a line of best fit.
Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Lucy can spend no more than $125 on props for a school play. She has already phurchased costume fabrics that cost $49. Write and solve an inequality to show how much more she spend on props.
Answer: 49+x≤ 125, where x = Amount she can spend more on props.
Now she can spend no more than $76 on props.
Step-by-step explanation:
Given: Lucy can spend no more than $125 on props for a school play.
I.e. Total money she can spend ≤ $ 125
She already purchased costume fabrics that cost $49.
Let x = Amount she can spend more on props.
Required inequality: 49+x≤ 125
Subtract 49 from both sides, we get
x≤ 76
Hence, now she can spend no more than $76 on props.
El peso promedio de 500 árboles de un vivero es de 70kg y la desviación estándar de 3kg. Suponiendo que los pesos se distribuyen normalmente, encontrar CUANTOS arboles pesan: a) Entre 60 y 75 kg b) Más de 90kg c) Menos de 64kg. D) 64 Kg
Answer:
Step-by-step explanation:
Resolvemos usando la fórmula de puntuación z
z = (x-μ) / σ, donde
x es la puntuación bruta
μ es la media poblacional = 70 kg
σ es la desviación estándar de la población = 3 kg
a) Entre 60 y 75 kg
Para x= 60kg
z = 60 - 70/3 kg
=-3.33333
Valor de probabilidad de la tabla Z:
P(x = 60) = 0.00042906
Para x = 75 kg
z = 75 - 70/3 kg
= 1.66667
Valor de probabilidad de la tabla Z:
P(x = 75) = 0.95221
P(x = 75) - P(60)
0.95221 - 0.00042906
b) Más de 90 kg
Para x> 90 kg
z = 90 - 70/3
= 6.66667
Valor de probabilidad de la tabla Z:
P (x <90) = 1
P (x> 90) = 1 - P (x <90) = 0
Número de árboles = 500
Por tanto, 500 × 0 = 0 árboles
c) Menos de 64 kg
x <64 kg
z = 64 - 70/3 kg
= -2
Valor de probabilidad de Z-Table:
P (x <64) = 0,02275
Hay 500 arboles
= 500 × 0.02275
= 11.375 árboles
D) 64 kilogramos
x = 64 kg
z = 64 - 70/3 kg
= -2
Valor de probabilidad de Z-Table:
P (x = 64) = 0,02275
Hay 500 arboles
= 500 × 0.02275
= 11.375 árboles

The area of Canada is approximately 1×10^7 square kilometers, and the area of Mexico is approximately 2×10^6 square kilometers. The area of Canada is approximately how many times the area of Mexico?
Answer:
5 times
Step-by-step explanation:
Given that,
The area of Canada is approximately 1×10⁷ square kilometers, and the area of Mexico is approximately 2×10⁶ square kilometers.
We need to find the area of Canada is approximately how many times the area of Mexico.
Dividing both areas as follows :
[tex]\dfrac{A_c}{A_m}=\dfrac{10^7}{2\times 10^6}\\\\\dfrac{A_c}{A_m}=5\\\\A_c=5A_m[/tex]
So, the area of Canada is approximately 5 times the area of Mexico.
