If ground be x axis and helicopter is at y distance then the point should be (x,112)

As we know that

In Q1 and Q2 ,y>0
in Q3 and Q4,y<0

The distance should be written as

+112ft

Half of Robert's piece of wire is equal to 2 thirds of Maria's wire. The total length of their wires is 10 feet. How much longer

Yuliya22 [10]

Answer:

let x be the Robert piece

y Maria's piece

x+y=10

0,5*x ( half of Robert piece)= 2/3 y( 2 thirds)

2 equations then

x+y= 10 then x= 10-y

0,5x= 0,67 y then we replace x by 10-y on the second equation and it gives

0,5(10-y)= 5-0,5y=0,67y

5= 1,17 y so y= 4,27 and then x= 10-y= 5,73

the question asks how much Robert wire is longer than Maria's wire

so we get x-y= 1,46

What does y equal. -4y+6y-5=9

Phoenix [80]

Answer:

y = 7

Step-by-step explanation:

$-4y+6y-5=9$

Add -4y and 6y

the band members sold 316 juice drinks for a fundraiser. they sold 52 more grape drinks than strawberry drinks. how many of each

Delvig [45]

S+g=316 "s"=strawberry "g"=grape
g=52+s

plug in for "g" to find "s"
s+(52+s)=316
2s+52=316
2s=316-52
2s=264
s=264/2
s=132

find "g"
g=52+132
g=184

Answer:

Nate is in Group 2.

Step-by-step explanation:

Total number of students is 24.

These 24 students are divided equally among 4 groups.

Compute the number of students in each group:

Number of students in each group $=\frac{24}{4}=6$

Thus, there will be 6 groups.

The groups will be:

Group 1: 1, 2, 3, 4, 5, 6

Group 2: 7, 8, 9, 10, 11, 12

Group 3: 13, 14, 15, 16, 17, 18

Group 4: 19, 20, 21, 22, 23, 24

It is provided that Nate is the 11th student.
