Find the values of c and d that would make the following equation true

Mathematics
1 answer:
Hitman42 [59]2 years ago
5 0

Answer:

c = 2, d = 3

Step-by-step explanation:

multiply factors on left side gives

9 c y^{3+d} = 18y^{6} ( divide both sides by 9 )

cy^{3+d} = 2y^{6}

For both sides to be equal then

c = 2 and 3 + d = 6 ⇒ d = 3

As a check

left side = 2y^{3} × 9y^{3} = 18y^{6} = right side

3x + 7m + 4x - 5m + 25
mart [117]
7x+2m+25 I believe is the answer
So basically I added the x’s first 3x+4x=7x
Next I added the m’s 7m-5m=2m
That left 25
And a + are left
So the two answers 7x+2m and add +25
7x+2m+25

A savings account earns 7.2 (APR) compounded monthly, so it earns 0.6% each month. Cooper has $1500 in the account now. if he de
iragen [17]

<u>Answer-</u>

<em>Cooper will receive </em><em>$12.00</em><em> at the end of the month.</em>

<u>Solution-</u>

Cooper has $1500 in the account now and he deposits an additional $500 at the beginning of the month.

So the total principal becomes 1500+500 = $2000

Given here,

APR = annual percentage rate = 7.2%

But as we have to calculate the monthly interest, so monthly interest rate would be =\dfrac{7.2}{12}=0.6\%

Time period = 1 month

So, the interest after 1 month will be,

\text{interest}=\dfrac{\text{Principal}\times \text{Rate of interest}\times \text{Time period}}{100}

=\dfrac{2000\times 0.6\times 1}{100}

=\$12.00

Therefore, Cooper will receive $12.00 at the end of the month.

It was estimated that because of people switching to Metro trains about 33000 of CNG 3300 tons of diesel and 21000 tons of petrol was saved by the end of year 2007 (I) find a fraction of the quantity of diesel saved to the quantity of petrol saved (ii) find the quantity of cng to the quantity of diesel saved

Answer:

(I) 11/70

(II) 1/10

Step-by-step explanation:

Metro trains contain 330,000 tons of CNG

3300 tons of diesel was saved

21000 tons of petrol was saved at the end of 2007

(I) The fraction of the quantity of diesel saved to the quantity of petrol saved can be calculated as follows

= 3300/21000

= 11/70

(II) The fraction of the quantity of CNG saved to the quantity of diesel can be calculated as follows

= 3300/33000

= 1/10
