on a shopping trip gill spends 1/3rd of his money in store A then he spends 1/3 of money he has left in store B. Finally he spends his remaining $12 in store C. How many dollars did he have at the start?

Answers

Answer 1

Answer:

$18

Step-by-step explanation:

Let the money he had at the start be $x

Store A = 1/3 of $x = $ x/3

Remaining = $ x/1 - $x/3 = $ 2x/3

He spends remaining $12. So,

2x/3 = 12

2x = 36

x= $18(Answer)

Mudrik installed a device on his car that guaranteed to increase his gas mileage by 10%. The gas mileage increased by 3 miles per gallon after installing the device. How many miles per gallon did he get before the device was installed?

Answers

Let x =  gas mileage before installing the device.

Because the gas mileage increased by 10% which is equal to 3 miles per gallon, therefore
0.1x = 3
x = 3/0.1 = 30 mi/gal

Answer: 30 miles per gallon

Bob can row 14 mph in still water. The total time to travel downstream and return upstream to the starting point is 2.8 hours. If the total distance downstream and back is 36 miles, determine the speed of the river (current speed).

Generally the equation for the time  is mathematically given as

elliot drove 202.8 miles and used 6.5 gallons of gasoline.How many miles did he travel per gallon of gasoline?

Answers

I think the answer is 31.2 miles per gallon
First you need to do long division to divide 202.8 by 6.5. To help you with this you can just imagine that the decimals arent there. For instance:

202.8 = 2,028

6.5 = 65

So it will be easier for you to divide it then you add the decimals back in later.

If you solved it correctly you should have gotten 31.2.

Answers

Okay, so with Isosceles triangles, because the two sides are equal, the two angles are as well. This means that angle D and angle F are 25%, so your answer is  180-50=E!

The measure of angle E is 0 degrees not provided in the options (A, B, C, or D), and the correct answer is "Cannot be determined."

To find the measure of angle E in degrees that the sum of angles in a triangle is 180 degrees.

From the given triangle, two angles with measures 50 degrees each (angle A and angle B), and one angle with a measure of 80 degrees (angle D).

To find the measure of angle E, we can use the equation:

Angle E = 180° - (angle A + angle B + angle D)

Angle E = 180° - (50° + 50° + 80°)

Angle E = 180° - 180°

Angle E = 0°

Final answer:

A real-world situation that can be solved using a two-step equation is calculating the total cost of a shopping trip. Let's say you go to a store and buy some items. Each item costs $5, and you buy 3 items. You also have a $10 coupon. To find the total cost, we can use a two-step equation: 3 * 5 - 10 = x. Solving the equation, we get x = 15.

Explanation:

A real-world situation that can be solved using a two-step equation is calculating the total cost of a shopping trip. Let's say you go to a store and buy some items. Each item costs $5, and you buy 3 items. You also have a $10 coupon. To find the total cost, we can use a two-step equation:

Step 1: Write the equation. Let x be the total cost.

Step 2: Solve the equation. The cost of the items is $5 per item, so the first step is to multiply 3 (number of items) by 5 (cost per item). Then subtract the $10 coupon from the total cost. The equation becomes 3 * 5 - 10 = x. Solving the equation, we get x = 5. Therefore, the total cost of the shopping trip is $15.

What is the distance between points 
(9, −7)
and 
(9, 4)
on a coordinate plane?

Answers

The answer would be 11 because the x's 9 doesnt have to move because they're on the same point. If you take 7 away from -7 you get zero. Add 4 to that 7 and you get 11. Make sesnse?
Hope this helped!

Final answer:

The distance between the points (9, -7) and (9, 4) is calculated by finding the absolute difference between the y-coordinates since the x-coordinates are the same. The distance is 11 units.

Explanation:

To calculate the distance between two points on a coordinate plane, you can use the distance formula, which is derived from the Pythagorean theorem. However, in this particular case, since the x-coordinates of the points (9, -7) and (9, 4) are the same, the distance is simply the absolute difference between the y-coordinates.

The formula to find the distance between two points (x1, y1) and (x2, y2) is:

d = √((x2 - x1)² + (y2 - y1)²)

So, substituting the known values:

d = √((9 - 9)² + (4 - (-7))²) = √(0 + 11²) = √121 = 11

Therefore, the distance between the points (9, -7) and (9, 4) on a coordinate plane is 11 units.

What is the area of this polygon 15m 10m 8m 9m

Answers

the area of the polygon is 10,800
Final answer:

The provided data is insufficient to accurately calculate the area of the polygon. With an assumption that the shape is a rectangle and the lengths are 15m and 8m, the area would be 120 square meters.

Explanation:

To calculate the area of a polygon, it's ideal to break down the polygon into simpler shapes like rectangles or triangles, for which we have well established formula for area. However, the information you've provided is inadequate to define a specific polygon shape like a rectangle or a square. Four sides could suggest a rectangle or a quadrilateral, but we don't know two essential properties: the arrangement of these sides and the measure of angles. For instance, if it was a rectangle, we'd look for pairs of equal lengths. If your shape is indeed a rectangle, and we assume that 15m and 8m are the length and width (or vice versa), we could calculate the area. For a rectangle, the area is calculated as length multiplied by width. In this case, it would be 15m*8m = 120 square meters.

A baseball dropped from the roof of a tall building takes 5.23 second s to reach the ground. How tall is the building?

Answers

The most general formula useful here would be

s = s0 + v0*t + (1/2)at^2, where s0 is the original height, v0 is the original velocity, a is the acceleration, and t is the time.

Here, s becomes 0 (baseball is on the ground)
           v0 is 0, since the initial speed of the ball was 0.
            a is the acc'n due to gravity, and is -9.8 m per (sec)^2 in the metric sys.
            t is known and is 5.23 sec

All that is left to find is s0, the original height (which is the building height).

0 = s0 + (0)(5.23 sec) + (1/2) (-9.8 m per sec^2)(5.23 sec)^2

 -s0     =         0             - (4.9 m per sec^2) ( 27.35 sec^2)

 So               s0 = 134 meters (approx)

The building height was approx. 134 meters.
