Answer:
Anna has $1460
Betty has $1060
Step-by-step explanation:
let Anna's money be x
and Betty's money be y
If Anna gave Betty $200, then they would have the same amount of money
Anna's money will reduce by 200
x=x-200
Betty's money will increase by 200
y= y+200
if they have the same amount of money, the difference will be zero
x-200=y+200
x-200-y-200=0
x-y-400=0
x-y=400--------------1
this means that Anna has $400 more than Betty
if Betty gave Anna $220, Anna would then have twice as much as Betty.
Betty's money will reduce by 220
y=y-220
Anna's money will increase by 220
x=x+220
Anna's money will double that of Betty's
x+220=2(y-220)
x+220= 2y-440
x=2y-440-220
x=2y-660--------------------2
put x= 2y-660 in eqn 1
(2y-660)-y=400-------------------------1
2y-y=400+660
y= 1060
so Betty has $1060
put y= 1060 in eqn 1
x-y=400
x-1060=400
x=400+1060
x=1460
so Anna has $1460

A four-person relay team completed a race in 60.4 seconds. On average, what was each runner's time?
Answer:
Each person did 15.1 seconds.
Step-by-step explanation: Just divide 60.4 seconds by 4 for the number of runners.
Solve 3/4x = 7 28/ 3
3/4x=728/3
x=728/3×4/3
x=32.556

Step-by-step explanation:
a number is 2/3 of another number. if the sum of the two numbers is 30, find the smaller number.
Answer: The numbers are 4 and 6.
Step-by-step explanation:
Let one number be represented as
x
and the other as
y
.
According to the problem:
x
=
2
3
y
and
x
+
y
=
10
From the second equation we get:
x
+
y
=
10
∴
y
=
10
−
x
(subtracting
x
from both sides)
Replacing the value of
y
in the first equation we get:
x
=
2
3
y
x
=
2
3
(
10
−
x
)
Multiplying both sides by
3
we get:
3
x
=
2
(
10
−
x
)
Opening the brackets and simplifying we get:
3
x
=
20
−
2
x
Add
2
x
to both sides.
5
x
=
20
Divide both sides by
5
.
x
=
4
Since from the second equation we have:
x
+
y
=
10
substituting
x
with
4
we get:
4
+
y
=
10
Subtract
4
from both sides.
y
=
6
Answer: The smaller number is 12.

Answer:
c+b=1000
Step-by-step explanation:
This problem can be solved by process of elimination. If the end weight is 1000, then at the equal sign, it should also be 1000. Since the last option is the only one with 1000, then it would be the only correct option.

Step-by-step explanation:
which point is closer to the x-axis (0.7, 21) or (0.77, 10)
Answer:
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
Please check the attached graph.
Step-by-step explanation:
We know that:
x-coordinate of any point P(x, y) gives its distance of that point from the y-axisy-coordinate of any point P(x, y) gives its distance of that point from the x-axisGiven the points
(0.7, 21)(0.77, 10)Let us say
A(0.7, 21)B(0.77, 10)FOR POINT A(0, 7)
As the y-coordinate of point A(0.7, 21) ⇒ y = 21We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point A(0.7, 21) from the y-axis is 21 units.
i.e.
[tex]d_A=21[/tex]
FOR POINT B(0.77, 10)
As the y-coordinate of point A(0.77, 10) ⇒ y = 10We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point B(0, 7) from the y-axis is 10 units.
i.e.
[tex]d_B=10[/tex]
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
Please check the attached graph.
Answer:
a=10
b=20
Step-by-step explanation:
A poster of the detroit lions football players uses a scale of 4 inches= 3 feet. If quarterback Matthew stafford is 8 1/2 inches tall on the poster, find his actual height.
Answer:
The actual height = 6.38 feet
Step-by-step explanation:
Given that a poster of the detroit lions football players uses a scale
of 4 inches = 3 feet
so
1 inch = 3/4 feetGiven that the poster's length:
[tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex] inch
We need to determine the actual height if quarterback Matthew Stafford is 8 1/2 inches tall on the poster.As 1 inch = 3/4 feetThus, we need to multiply 8.5 inches by 3/4 to determine the actual height of the player.
Actual height = 8.5 × 3/4 feet
= 6.38 feet
Therefore, the actual height = 6.38 feet

find the missing measures
Answer:
8 cm and 28 cm
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
(i)
Here A = 48, b = AB and h = DE = 6 , then
AB × 6 = 48 ( divide both sides by 6 )
AB = 8 cm
(ii)
Here A = 252, b = PQ = 9 and h = RT , then
9 × RT = 252 ( divide both sides by 9 )
RT = 28 cm
