Answer:

10 gallons of gas.

Step-by-step explanation:

250/9 = how many miles 1 gallon of gas will take

250/9 = 27.78

1 gallon of gas = 27.78 miles

275/27.78 = 9.90 gallons

9.90 gallons round up to 10 gallons

Therefore, Trey would need 10 gallons of gas to drive 275 miles.

If we are given x such that 25^x-9^y=18 and 5^x-3^y=3, compute 5^x+3^y.

leonid [27]

25 = 5*5 and 9 = 3*3, which we can exploit to write

$25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2$

so that this expression is actually a difference of squares. We can factorize this to get

$(5^x-3^y)(5^x+3^y)=18$

and given that $5^x-3^y=3$ , we divide both sides by this to get

$5^x+3^y=\dfrac{18}3=\boxed{6}$

the volume of a cylindrical tank is 936cubic meter. if its height is 6 meter determine the base area of the tank

vladimir2022 [97]

Answer:

156 square m

Step-by-step explanation:

$volume \: of \: cylindrical \: tank \\ = area \: of \: base \times height \\ \\ 936 = area \: of \: base \times \: 6 \\ \\ area \: of \: base = \frac{936}{6} \\ \\ area \: of \: base = 156 \: {m}^{2}$

Emma uses turquoise beads to make bracelets to sell at an event. The total amount Emma earns, y, is proportional to the number

NNADVOKAT [17]

<h3>The equation represents the total amount Emma earns at the event is y = 10x</h3>

<em><u>Solution:</u></em>

Given that,

<em><u>The total amount Emma earns, y, is proportional to the number of bracelets, x, she sells</u></em>

$y \propto x\\\\y = kx -------- eqn\ 1$

Where,

y is the total amount Emma earns

x is the number of bracelets

k is the cost of each bracelet

<em><u>Emma earns $10 for each sold bracelet</u></em>

Therefore, k = 10

Thus, eqn 1 becomes,

Thus the equation represents the total amount Emma earns at the event is found
