Based on the given conditions, formulate:
Calculate the product or quotient: 240
get the result: 240
Answer: 240
To find this answer, we had to use the expression 80 * 3, therefore making it the answer.
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
<span>The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
</span><span>use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26
b = 22</span>
Answer:
original width= 9.6 feet
original length = 38.4 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the formula
P =2w +2 L
Where:
P=perimeter
W= width
L = length
Since the field is 4 times as long as it is wide
L= 4W
So, if the length is decreased by 10 feet and the width is increased by 2 feet, the perimeter will be 80 feet.
Mathematically speaking
80= 2 (W+2) + 2(L-10)
Simplifying:
80 = 2w+4 +2L-20
Replacing the value of L by 4W
80 = 2W +4 +2(4W)-20
Solving for W:
80=2W +4 +8W-20
80-4+20= 2W+8W
96= 10W
96/10 =W
W= 9.6 feet
Replacing the value of W in the Length equation:
L =4W
L = 4 (9.6)
L = 38.4 feet
Answer:
Yes, the point makes the inequality true
Step-by-step explanation:
y < 10x+8
Substitute x =9 and y=8 into the inequality
8 < 10*9+8
8<90+8
8<98
This is true so the point makes the inequality true
