Answer:
The area increased by a factor of 4
Step-by-step explanation:
If the scale factor is 4 and only the height changes
A = 1/2 bh
A = 1/2 b(4h)
A = 1/2 bh(4)
A = A4
The new area is the old area increased by 4

Answer:
Betty produced 613 gallons while Georgette produced 851 gallons
Step-by-step explanation:
Let Betty be X and Georgette be Y
The first equation
Y= 2x-375
Second equation
X+Y = 1464
This is simultaneous equation.
We are using substitution method
From equation 1 the value of Y= 2x-375
Substitute for the value of y in equation 2
X+Y= 1464
X + 2X - 375= 1464
Collect like terms
3x=1464+375
3x= 1839
X= 613
To get the value of Y
Substitute for Y in equation 1
Y= 2x - 375
Y= 2(613) - 375
Y= 1226 - 375
Y= 851
Since X= Betty and Y = Georgette
Betty produced 613 gallons while Georgette produced 851 gallons
The school club needs additional 43.25 feet of rope.
<u>Step-by-step explanation</u>:
Rope containing 2 pieces have 16 yards in length.
Rope containing 1 piece have 12.5 yards in length.
Rope containing 1 piece have 123.25 feet in length.
We will need this conversion formula:
1 yard = 3 foot.
Now let us find dimensions of each part.
Rope containing 2 pieces having 16 yards in length = 2 16
= 32 yards
= 32 3
= 96 feet.
Rope containing 1 piece having 12.5 yards in length or 37.5 feet.
Rope containing 1 piece having 123.25 feet in length.
Adding the three measures = 96 + 37.5 +123.25
= 256.75 feet.
Rope required = 300 - 256.75
= 43.25 feet.
