Answer:
8 1/8 hours
Step-by-step explanation:
Jerry played with 3 friends today, all at different times.
Tommy = 1 7/8 hours
Nathan = 1 3/4 hours
Chris = 3 3/2 hours
How many hours did Jerry play with his 3 friends today?
Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2
= 15/8 + 7/4 + 9/2
= (15+14+36)/8
= 65/8
= 8 1/8 hours
Find the length of side x I simplest radical form
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = [tex]\sqrt{61}[/tex]
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² = [tex](\sqrt{61})^2[/tex] + x²
x² = 100- 61
x² = 39
x = √(39)
Option A will be the answer.

The freshman class of 175 students went on a field trip. For transportation, they needed both vans (which hold 5 students each) and buses (which hold 35 students each). There was a total of 11 vehicles used.
How many of each type of vehicle did they use?
Vans: _________________
and
Buses _________________
.
Answer:
You will need 7 vans and 4 buses
Step-by-step explanation:
7 vans would take care of 35
4 buses would take care of 140 kids
and it uses a total of 11 vehicles
Hope this helps
Answer:
Vans = 7
Buses = 4
Step-by-step explanation:
x = vans
y = buses
x + y = 11 (1)
5x + 35y = 175 Divide this equation by 5
x + 7y = 35 (2)
============
Subtract (1) from (2)
x + 7y = 35
x + y = 11
6y = 24 Divide by 6
6y/6 =24/6
y = 4
===========
x + y = 11
x + 4 = 11
x = 11 - 4
x = 7
Now Let's check it
x is the number of vans which holds 5 students each
7 * 5 = 35
y is the number of buses which holds 35 students each
4 * 35 =140
Total number of students = 35 + 140 = 175
So it checks.

1. What's the probability that a respondent was a boy AND in year 8?
Answer:
8/18?
Step-by-step explanation:
y=-4x-3
y=-2x+1
x=?
y=?
Answer:
x = -2
y = 5
Step-by-step explanation:
y = -4x - 3
y = -2x + 1 Multiply this whole equation by -1
-1(y = -2x + 1) = -y = 2x - 1
y = -4x - 3
-y = 2x - 1
0 = -2x - 4
4 = -2x
x = -2
y = -4x - 3 (Plug in x)
y = -4(-2) - 3
y = 8 - 3
y = 5
Ariana compró cierto número de sacos de azúcar por S/. 675 y luego los vendió por S/. 1 080, ganando S/. 3 por cada saco. ¿Cuántos sacos de azúcar compró?
Responder:
135
Explicación paso a paso:
Número de bolsas compradas = x
Costo total de compra = 675
Costo total de ventas = 1080
Beneficio por bolsa = 3
Por eso :
Beneficio total + costo total de compra = costo total de ventas
3x + 675 = 1080
3x = 1080 - 675
3 veces = 405
x = 405/3
x = 135
Se compraron 135 bolsas

A train, initially moving at 12 m/s, speeds up to
36 m/s in 120 s. What is its acceleration?
Answer:
Acceleration is 35,9. I think so
Step-by-step explanation:
v0=12m/s
v=36m/s
t=120s
a=?
a=v–v0/t,
a=36 - [tex]\frac{12}{120}[/tex]
a=36-0,1

6. There are 785 students in the senior class. If there are 77 more females in
the class than males, how many male and female seniors are there?
... please solve this using if systems of equations
Answer:
there are 431 females and 354 males in the class
Step-by-step explanation:
Let the number of females student in the class be x
Let the males by y
If there are 785 students in the senior class, then;
x+y = 785 .... 1
If there are 77 more females in the class than males, then;
x = y+77 ....2
Substitute 2 into 1
y+77+y = 785
2y = 785 - 77
2y = 708
y = 708/2
y = 354
Since x = 785 - y
x = 785 - 354
x = 431
Hence there are 431 females and 354 males in the class
