Derek can do 50 pushups. Roger can do
8% fewer than Derek can do. How many
pushups can Roger do?
Answer: 40
Step-by-step explanation: 50x0.8=40
Okay, maybe im wrong? But i dont see how its 4 thats more than half.
Rodger can do 46 pushups.
50 * 0.92 = 46
Edit: To better clarify, 0.92 is from 1.00 - 0.08.
... 8 percent fewer than 100 percent is 92 percent; 1.00 - 0.08 = 0.92
Keep in mind that:
1.00 = 100%
0.08 = 8%
0.92 = 92%
After finding this you may multiply 50 * 0.92 to get 46.

Step-by-step explanation:
The money collected from a Saturday car wash are directly proportional to the number of cars washed. The total money collected after 7 cars is $140. Write an direct variation equation relating the money collected (m) and the number of cars washed
Answer:
[tex]m=20c[/tex]
Step-by-step explanation:
Let m represent the total money collected and c represent the amount of cars washed.
We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:
[tex]m=kc[/tex]
Where k is a constant.
We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:
[tex]140=7k[/tex]
Find k. Divide both sides by 7:
[tex]k=20[/tex]
So, the value of k is 20.
We can now substitute k back into our direct variation equation:
[tex]m=20c[/tex]
This means that every car costs $20 to wash.
And we're done!

Agustín y Bárbara salen al mismo tiempo y del mismo lugar, por el mismo camino. Agustín camina a 5km/h y Bárbara a 3km/h. Luego de recorrer 7km, Agustín emprende el regreso, ¿a qué distancia de la partida se encuentra con Bárbara? Si en el momento del encuentro también Bárbara emprende el regreso, ¿cuántos minutos después que Agustín llega Bárbara al punto de partida?
Answer:
Ok, primero Agustín camina a 5km/h.
Cuando el recorre 7km, el regresa.
El tiempo en el que sucede esto es a:
7km/5km/h = 1.4 h
La ecuación para Agustín es:
A(t) = 5km/h*t para 0h ≤ t ≤ 1.4h (ida)
A(t) = 7km - 5km/h*(t - 1.4h) para 1.4h ≤ t. (vuelta)
Hacemos lo mismo para Barbara:
7km/3km/h = 2.5h
La ecuación para ella es:
B(t) = 3km/h*t para 0h ≤ t ≤ 2.5h (ida)
B(t) = 7km - 3km/h*(t - 2.5h) para 2.5h ≤ t. (vuelta)
a) ¿a qué distancia de la partida se encuentra con Bárbara?
Tenemos que ver cuando A(t) = B(t).
Para ello comparamos la vuelta de Agustín con la ida de Barbara.
7km - 5km/h*(t - 1.4h) = 3km/h*t
7km - 5km/h*T + 7km = 3km/h*T
14km = 8km/h*t
14/8 h = 1.75h = t.
Entonces la posición en la que se encuentran es:
B(1.75h) = 3km/h*1.75h = 5.25km
Ellos se encuentran a 5.25 kilómetros de el punto de partida.
b) Si en el momento del encuentro también Bárbara emprende el regreso
(Es decir, en este momento Barbara comienza a regresar).
Entonces ella para regresar al punto de inicio tiene que recorrer 5.25km con una velocidad de 3km/h.
Tb = 5.25km/3km/h = 1.75h
Barbara tarda 1.75 horas en regresar.
Agustín también tiene que recorrer 5.25 km para regresar, pero su velocidad es 5km/h.
Ta = 5.25km/5km/h = 1.05h.
La diferencia entre los tiempos es:
Tb - Ta =1.75h - 1.05h = 0.7h
Entonces Barbara llega al punto de partida 0.7 horas después que Agustín.
Pero queremos esto en minutos.
1 hora = 60 minutos.
0.7 horas = 0.7*(60 min) = 42min
Barbara llega 42 minutos después que Agustín.

solve for y 5y-28=7(y=2) Simplify your answer as much as possible.
Answer: Y=7
Step-by-step explanation: if you have to find y then it’s
5y-28=7
+28+=+28 adding 28 to both sides to have y by itself -28+28=0 & 28+7=35
5y=35 then you divide by 5 on both sides
So it’s y= 7

Answer:
1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x
Step-by-step explanation:
1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)
2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)
Bringing us to the answer → 16 + 2x!

A round trip from Montreal to LA is 2,688 miles and takes an airline 9 hours and 20 minutes. Given the outbound trip is the same distance as the return trip, and the speed of the plane was 25%faster on the return trip, how long did the return trip take? Answer to the nearest minute.
Answer:
4.074 hours
Step-by-step explanation:
r =
The formula for speed = Distance × Time
Hence,
Let the outbound speed = r
return trip speed = r + 25x/100 = 125r/100 = 1.25r
Note that: 9 hours and 20 minutes = 9.167
Let t1 and t2 be the time taken to travel on way and return journey.
t1 + t2 = 9 hr 10 min = 9.167 hrs
Hence:
2688/r + 2688/1.25r = 9.167
LCM(1.25r)
(2688 × 1.25) + 2688 /1.25r= 9.167
3360 + 2688 = 9.167 × 1.25r
6048 = 11.45875r
r = 6048/11.45875
Outbound trip rl = 527.8062615904876mph
Return trip speed = r + 25x/100 = 125r/100 = 1.25r
= 1.25 ×
659.75782699mph
Time for return trip = Distance/Speed
= 2,688 miles/659.75782699mph/
= 4.0742222222 hours
Approximately = 4.074 hours
What is the slope of this line?
A. −5
B. 5
C. −15
D. 15
Picture Down Below
Answer:
It seems that the slope of this line is 1/5, yet none of the answers correspond to this. Double-check by finding two points on the line, and use the slope formula: (y2-y1/x2-x1). Also, remember that slope is rise/over run. I hope this can guide you!
Answer: the answer is not included in the options
Step-by-step explanation:
The slope of the line can be depicted by the following formulas: 1. Rise/run 2. Y1-y2/ x1-x2
If we were to use the second formula and “plug” in numbers for the variables, the slope we calculate is less than 1
