Answer:

Hello! Your answer is BELOW

Step-by-step explanation:

Car will cover 16 miles in 1 gallon of the gas.

We can solve this question by unitary method.

∵ A car used $\frac{1}{64}$ gallons of gas to drive the distance = $\frac{1}{4}$ miles

∴ Car used 1 gallons to drive the distance = $\frac{1}{4} \\\\\frac{1}{64}$

= $\frac{64}{1} X \frac{1}{4}$

= $\frac{64}{4}$

= 16 miles

Therefore, car will cover 16 miles in 1 gallon of the gas.

Hope I helped! Hope you make an 100%.

The lengths of the sides of a triangle are in the ratio of 6:6:5. The perimeter of the triangle

Oliga [24]

Hello!

Answer:

12 cm, 12 cm, 10 cm.

Step-by-step explanation:

Given:

Perimeter, or P = 34 cm

Ratio of sides = 6 : 6 : 5

To find the length of each side, we can use a variable in the ratio to find the perimeter:

34 = 6x + 6x + 5x

Combine like terms:

34 = 17x

Solve for x:

34/17 = 17x/17; x = 2

Plug in this value of "x" into each expression for the side-lengths:

6(2) = 12 cm

5(2) = 10 cm

Therefore, the lengths of each side of the triangle are 12 cm, 12 cm, 10 cm.

Hope this helped you! :)

PLEASE HELP!!!

Alexus [3.1K]

We have to calculate the length of stack RM. This is a pyramid with a rectangular base. If TS = 12 cm, then OM = TS / 2 = 12 / 2 = 6 cm. And since we already know that RO = 15 cm, we will use the Pythagorean theorem: RM^2 = 15^2 + 6^2; RM^2 = 225 + 36 = 261; RM = sqrt ( 261 ) ; RM = 16.1555 ( or 16.2 rounded to the nearest tenth ). Answer: RM = 16.2 cm<span>.</span>

The sum of the first five terms of 3,-9,27,-81

xeze [42]

Answer:

Step-by-step explanation:

The answer above is correct, but I do want to elaborate on how to receive this answer;

This pattern takes an alternate of positive and negative numbers at a time. If you can see for each positive number, there is a negative consecutively. Imagine these values were all positive. What would then be the difference between each? 3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81, and so each number would be 3 times the other. Now let us go back to the state we have at hand, negative and positive numbers. 81 * 3 = 243, and as we alternate between negative and positive numbers, 243 should be positive as the previous number - 81, is negative. We have now received our 5th term!

The questions asks us to determine the sum of each of the terms however, so let us do so;

$3 - 9 + 27 - 81 + 243,\\- 6 + 27 - 81 + 243,\\21 - 81 + 243,\\- 60 + 243,\\\\183\\Solution = 183$

Hope that helps as well!
