Answer: X = 7√2
Step-by-step explanation:
Let first Consider triangle BDC,
Cos C = adjacent/ hypothenus
Cos C = 7 / x ...... (1)
Also, let consider triangle ABC
Cos C = adjacent / hypothenus
Cos C = x / 14 ....... (2)
Since angle C is the same, equate equation 1 to 2
7/ x = x / 14
Cross multiply
X^2 = 98
Make x the subject of formula
X = sqrt (98)
X = sqrt ( 49 × 2 )
X = sqrt (49) × sqrt (2)
X = 7 sqrt(2)
X = 7√2
Answer:
Step-by-step explanation:
It would be 2.43ft cubed. You first have to multiply 6 x 9 to get 54 and then Do 54 x 4.5 to get 243 ft cubed. Next you have to put it in fraction form 243/100. After that you have to divide 243 by hundred( you can do this by moving the decimal place two places to the left) and you get the answer 2.43 ft cubed
Answer:
6/5 or 1 1/5
6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)
Step-by-step explanation:
4/10*3
They both need to be a fraction, and any number over 1 = that number. So,
4/10*3/1
4*3=12
10*1=10
12/10
Then, you have to simplify the fraction.
6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)
or 1 2/10= 1 1/5
Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.
in form of multiplication is 
.
<u>Step-by-step explanation:</u>
We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .
Here , we need to convert to the product of multiplication
a^2-b^2-4b-4 or , :
⇒
We know by identity that , 
⇒ 
Taking common term out as -4 :
⇒
Therefore , in form of multiplication is .
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
