Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 1/2 miles per hour
Complete question is;
Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 ½ miles per hour faster than autumn. What is the average speed of each?
Answer:
Autumn's average speed is 1.3158 mph
Summer's average speed is 11.1843 mph
Step-by-step explanation:
We are told that they live 25 miles from each other.
They left their houses at 4pm and met at 6 pm. This means they met 2 hours later.
Now, summer ran 8.5 mph faster than autumn.
This means if autumn's speed is "x", then summer ran 8.5x mph
Thus, total distance covered by summer is; d_summer = 8.5x * 2 = 17x
Total distance by autumn is; x * 2 = 2x
Since their houses are 25 miles apart.
Thus;
17x + 2x = 25
19x = 25
x = 25/19
x = 1.3158 mph
Thus, autumn's speed is 1.3158 mph
Summer's speed is 1.3158 × 8.5 = 11.1843 mph

Aaron is growing two tomato plants. At the last measurement, the first plant was 6.53 inches tall and the second was 2.7 inches tall. How much taller was the larger plant?
Answer:
3.83 inches
Step-by-step explanation:
Aaron is growing two tomato plants
The first plan was 6.53 inches tall
The second plant was 2.7 inches tall
Therefore the height of the tall plant against the smaller one can be calculated as follows
= 6.53-2.7
= 3.83
Hence the larger plant is 3.83 inches taller

The perimeter of a rectangular pool is 48 feet. Its length is 4 feet more than its width.
Let the width of the pool be represented by x.
Which equation below can be used to describe the situation?
Answer:
48=2(x+4)+2x
Step-by-step explanation:
Step one:
given data
Perimeter= 48ft
let the with be x
length= x+4
Step two:
the expression for the perimeter is
P=2L+2W
substituting
48=2(x+4)+2x
48=2x+8+2x
solve for x
48=4x+8
48-8=4x
40=4x
x=40/4
x=10ft
Step three:
the width is 10 ft
the lenght= x+10
length= 10+10= 20ft

Entre Ana y Sergio tienen $500, pero Sergio tiene el doble de dólares que Ana. ¿Cuánto tiene cada uno? Halle la solución por el Método Gráfico Ana : x ; Sergio :y { + = = { + = − + = �
Answer:
Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.
Step-by-step explanation:
Consideramos que la mejor estrategia para resolver este problema consiste en leer cuidadosamente cada frase del enunciado, traducirlo matemáticamente y utilizar software gráfico para determinar la solución de las ecuaciones resultantes:
1) Entre Ana y Sergio tienen $ 500
[tex]x + y = 500[/tex] (Eq. 1)
Donde:
[tex]x[/tex] - Cantidad de dinero de Ana, medida en dólares.
[tex]y[/tex] - Cantidad de dinero de Sergio, medida en dólares.
2) Sergio tiene el doble de dólares que Ana
[tex]2\cdot x - y = 0[/tex] (Eq. 2)
En consencuencia, tenemos un sistema de dos ecuaciones lineales con dos incógnitas, lo que nos permite la posibilidad de encontrar una solución única y utilizar un plano cartesiano para su resolución. Mediante software gráfico (véase imagen adjunta) encontramos que la solución del sistema es:
[tex](x,y) = (166,67, 333,33)[/tex]
Ana tiene 166,67 dólares, mientras que Sergio tiene 333,33 dólares.
Logan bought a baseball bat on a trip. The baseball bat is 29 inches long Logan thinks he can bring the baseball bat home in his suitcase. Is he correct? Use your understanding of the Pythagorean theorem to explain your answer
Answer:
Step-by-step explanation:
Kindly find attached a description of Logan's suit case
given data
dimension of suitcase
adj, length=24in
opp, width=18in
dimension of base ball bat= 29in
we want to know if the bat can fit in the case, a way out is to solve for the diagonal or hypotenuse of the case using Pythagoras theorem.
we know that
hyp^2= opp^2+adj^2
hyp=√opp^2+adj^2
hyp=√18^2+24^2
hyp=√324+576
hyp=√900
hpy=30in
this means that the diagonal of the case is 30 in, seeing that the bat is 29 in, the bat cannot fit into the case
Since in the given situation, the diagonal of the case is 30 in and the baseball bat is 29 in, so the bat cannot fit into the case.
Pythagorean theorem:The dimension of a suitcase is adj length=24in and opp width=18in
Now here we apply the above theorem for determining the diagonal or hypotenuse
So, the calculation is as follows:
[tex]hyp^2= opp^2+adj^2\\\\hyp=\sqrt opp^2+adj^2\\\\hyp=\sqrt 18^2+24^2\\\\hyp=\sqrt324+576\\\\hyp=\sqrt900[/tex]
hyp=30in
Due to the above calculations, we can say that the bat cannot fit into the case

Step-by-step explanation:
9 can go into 29 3 times with 2 leftover.
Answer: 3.2 or 3.22

Hideo Yamata makes a deposit of $2,235. He remembers that the checks he deposited total twice the amount of currency he deposited. How much did he deposit in checks?
Answer:
Total amount deposited in checks is $1490
Step-by-step explanation:
Amount deposited by Yamata = $2235.
The amount of checks is twice the amount of currency deposited. Let the amount of currency deposited be represented by x.
So that,
Amount of checks = 2x, then;
2x + x = 2235
3x = 2235
x = [tex]\frac{2235}{3}[/tex]
= 745
The amount of currency deposited is $745.
Therefore,
amount deposited in checks = 2 x $745
= 1490
Total amount deposited in checks is $1490.

Answer:
The vertical asymptote is x = -3
Step-by-step explanation:
Vertical asymptotes are found by setting the equation in the denominator equal to zero.
x+3=0
To solve for x, all you need to do is bring the 3 to the other side of the equation in order to isolate the x. By doing so the 3 become negative because you switched sides of the equation.

The original price of a $250 coat increased 7% last year. The coat is now on sale for one-half off of the new price. What is the sale price? Please help y’all
Answer:$133.75
Step-by-step explanation: So you would convert the 7% into a decimal of .07. You would multiply that by the original price of $250 and you would get $17.5 which is how much it increased. That would equal $267.5 And you would just divide that in half for your final answer of $133.75. Super easy if you know what to do. :)
Danielle is ordering costumes for her dance recital. The company Danielle is ordering from charges $19 per costume and a shipping fee of $9. Based on this information, which function can be used to represent the relationship between the total cost, k, and the number of costumes Danielle orders, u? A. k = 9u + 19 B. k=19u−9 C. k = 19u + 9
D. k=9u−19
PLEASE HURRY ILL MAKE MOST BRAINLIEST!!!!
Answer:
Step-by-step explanation:
C. Cost = $19 x u + $9shipping fee
So k = 19u + 9
The function that represent the information is k = 19u + 9
The shipping fee = $9
The company charges $19 per costume.
The shipping fee is acting like a constant in the linear equation while the amount charged for the costumes is dependent on the value u, which is the number of costumes purchased.
k = total cost
number of costumes she orders = u
Therefore, the equation can be represented as follows
k = 19u + 9

Maria needs to measure out liter of broth for a recipe. If she only has a container that holds liter, how many containers will she need to fill?
Answer:
20 containersStep-by-step explanation:
Let us restructure the question as:
Maria needs to measure out 10 liter of broth for a recipe. If she only has a container that holds 0.5 liter, how many containers will she need to fill?
Total litre of broth measured = 10litres
If a container holds 0.5litre, then the number of container she will need will be calculated as thus:
1 container = 0.5 liter of broth
x container = 10 liters of broth
Cross multiply
0.5 * x = 1 * 10
0.5x = 10
Divide both sides by 0.5
0.5x/0.5 = 10/0.5
x = 20
Therefore she will need to fill 20 containers.
Note that the amount of liters used in question were assumed. Same calculations can be followed for any other values given.
