The LCM of two numbers is 14 times their HCF. The sum of LCM and HCF is 600. If one number is 280, then find the other number.
Answers
Given:
The LCM of two numbers is 14 times their HCF.
The sum of LCM and HCF is 600.
One number is 280.
To find:
The other number.
Solution:
Let HCF of two numbers be x.
The LCM of two numbers is 14 times their HCF.
LCM = 14x
The sum of LCM and HCF is 600.
[tex]14x+x=600[/tex]
[tex]15x=600[/tex]
[tex]x=\dfrac{600}{15}[/tex]
[tex]x=40[/tex]
So, HCF = 40 and the LCM is
[tex]LCM=14(40)[/tex]
[tex]LCM=560[/tex]
We know that, if a and b are two numbers, then
[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]
One number is 280.
[tex]280\times b=560\times 40[/tex]
[tex]b=\dfrac{560\times 40}{280}[/tex]
[tex]b=2\times 40[/tex]
[tex]b=80[/tex]
Therefore, the other number is 80.

7 Eva has 4 m of ribbon for wrapping gifts.
She needsm for each gift.
How many gifts can Eva wrap?
Answers
Answer: 6 gifts.
Step-by-step explanation:
I found the question elsewhere and it states that Eve needs 2/3 m for each gift.
Since Eve has 4 m, the number of gifts she can wrap is the 4 m she has divided by the 2/3 m required for each gift.
= 4 ÷ 2/3
= 4 × 3/2
= 12/2
= 6 gifts.
Note: When dividing by a fraction, you can multiply by it's inverse.

4. Jake wants to make a garden with a border in the corner of his yard. He has lumber in several different lengths. Which three lengths could NOT be used to make a right triangle to fit into the corner of his yard? O 5 ft., 12 ft., 13 ft. O 9 ft., 12 ft., 15 ft. O 16 ft., 12 ft., 20 ft. 0 0 O 10 ft., 12 ft., 15 ft.
Answers
Answer:
10 ft., 12 ft., 15 ft.Step-by-step explanation:
Note that for a right triangle, the sum of the square of the hypotenuse is equal to the sum of square of the opposite and the adjacent.
Note that the hypotenuse is the longest side
Checking the given sides 10 ft., 12 ft., 15 ft.
Hypotenuse = 15ft (longest side)
Take the square of 15
15² = 225
Take the sum of square of other two sides
12²+10²
= 144 + 100
= 244
Since 225≠244, hence the three length could not be used to make a right triangle to fit into the corner of his yard

combine like terms
-1 + 12x = -5x + 2
12x = -5x + 3
17x = 3
x = 3/17
5 - 4x + 6 + 8x = -5x + 2
4x + 11 = -5x + 2

Taut learns that when she spends $65.00 on supplies she is able to grow 162.5 pounds of tomatoes. How many dollars is Taut spending per pound of tomatoes grown?
Answers
Answer: $0.4 is spent by Taut per pound of tomatoes grown
Step-by-step explanation:
Given : On spending $65.00 , tomatoes grown by Taut = 162.5 pounds
To find : Taut expenditure per pound of tomatoes grown = ?
As it is given that :
162.5 pounds of tomatoes are grown by spending = $65.00
Thus 1 pound of tomatoes are grown by spending = [tex]\frac{65.00}{162.5}\times 1=0.4[/tex]
Thus $0.4 is spent by Taut per pound of tomatoes grown
In QRS q=9.6 inches r=9.9 inches and S=92 Find the length of a to the nearest 10th of an inch

Step-by-step explanation:
delta math gave me the answer
The length of a to the nearest 10th of an inch is 13.6 inches.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
In ΔQRS q=9.6 inches r=9.9 inches and S=92.
So, s² = q² + r² - 2qr cos s
s² = 9.6² + 9.9² + 2(9.6)(9.9) cos 92.
s² = 190.71 + 190.08 x (-0.035)
s² = 183.52
s = 13.55
s = 13.6 inches
