Answer:
22m
Step-by-step explanation:
Let height of flagpole=h
AB==17 m
(1 degree= 60 minute)
We have to find the approximate height of the flagpole.
In triangle CDA,
In triangle CDB,
Substitute the value
Substitute the value
Hence, the height of the flagpole=22 m
Answer:
60x + 45y = 2400
Step-by-step explanation:
60 is the amount for normal tickets (x) and 45 is the amount for reserved tickets (y). 2400 is the total amount! Hope this helps! Can I please have brainliest!?!
The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
Answer:
3x-4y=15
7x+y=4
Solve7x+y=4 for y:
7x+y=4
7x+y+−7x=4+−7x (Add -7x to both sides)
y=−7x+4
Step: Substitute −7x+4 for y in 3x−4y=15:
3x−4y=15
3x−4(−7x+4)=15
31x−16=15 (Simplify both sides of the equation)
31x−16+16=15+16 (Add 16 to both sides)
31x=31
(Divide both sides by 31)
x=1
Step: Substitute 1 for x in y=−7x+4:
y=−7x+4
y=(−7)(1)+4
y=−3(Simplify both sides of the equation)
Answer: x=1 and y=−3
Answer:
First
Step-by-step explanation:
Any multiplicand multiplied by x-2 must be of the first degree for the product to be of the second degree (such as x^2 + 11x - 10 is).
