Sadie has a cousin Nanette in Germany. Both families recently bought new cars and the two girls are comparing how fuel efficient the two cars are. Sadie tells Nanette that her family’s car is getting 42 miles per gallon. Nanette has no idea how that compares to her family’s car because in Germany mileage is measured differently. She tells Sadie that her family’s car uses 6 liters per 100 km. Which car is more fuel efficient?

(1 mile = 1.609 km and 1 gallon = 3.79 liters)

Answer:

Step-by-step explanation:

Simplifying

7x + 2y = 180

Solving

7x + 2y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

7x + 2y + -2y = 180 + -2y

Combine like terms: 2y + -2y = 0

7x + 0 = 180 + -2y

7x = 180 + -2y

Divide each side by '7'.

x = 25.71428571 + -0.2857142857y

Simplifying

x = 25.71428571 + -0.2857142857y

Answer:

Cost of small box = $13

Cost of large box = $18

Step-by-step explanation:

Let the cost of small box of candy = $s

And the cost of large candy box = $b

Beth sold 9 small and 10 large boxes of candies for $297.

9s + 10b = 297 -----(1)

Sarah sold 8 small and 5 large boxes of candies for $194.

8s + 5b = 194 -------(2)

Multiply equation (2) by 2 then subtract equation (1) from (2).

2(8s + 5b) - (9s + 10b) = (2×194) - 297

16s + 10b - 9s - 10b = 388 - 297

7s = 91 ⇒ s = $13

From equation (2),

(8×13) + 5b = 194

104 + 5b = 194

5b = 90

b = $18

Answer:

Step-by-step explanation:

From the picture attached,

Lines 'p' and 'q' are the parallel lines and line 't' is a transversal intersecting these lines.

Two pairs of angles (∠2 and ∠7) and (∠4 and ∠5) are the alternate interior angles.

Similarly, two pairs of (∠1 and ∠8) and (∠3 and ∠6) are the alternate exterior angles.

Alternate interior angles are the interior angles between the parallel lines and the transversal line while alternate exterior angles are vertically opposite angles to these interior angles.

Answer:

Step-by-step explanation:

For the first one you can round 156 to 160 because 16 divided by 8 is 2 so 160 divided by 8 is 20. For the second one you can round 48 to 50 and 32 to 30 because 50 times 30 is 1,500. For the last one, add the 12 to the -8 which is 4. b=4.

a. False. Not every isosceles triangle is an equilateral triangle b. True. Every equilateral triangle has angle measures of 60 degrees. c. True. Every square is a rectangle. d. False. Not every trapezoid is a parallelogram. e. True. Every triangle is convex.

a. False. An isosceles triangle is a triangle with at least two sides of equal length, but it does not necessarily have all three sides equal. An equilateral triangle, on the other hand, is a specific type of isosceles triangle where all three sides are equal. Therefore, not every isosceles triangle is an equilateral triangle.

b. True. An equilateral triangle is a triangle with all three sides and angles equal. Since the sum of angles in a triangle is always 180 degrees, each angle in an equilateral triangle is 60 degrees. Therefore, every equilateral triangle has angle measures of 60 degrees.

c. True. A square is a special type of rectangle where all four sides are equal in length and all four angles are right angles. Since a rectangle is defined as a quadrilateral with all angles equal to 90 degrees, every square, by definition, is a rectangle.

d. False. A trapezoid is a quadrilateral with at least one pair of parallel sides. A parallelogram, on the other hand, is a quadrilateral with both pairs of opposite sides parallel. While every parallelogram is a trapezoid, not every trapezoid is a parallelogram. A counterexample would be a trapezoid with only one pair of parallel sides.

e. True. Convexity in a triangle refers to the property that all interior angles are less than 180 degrees. In other words, the triangle does not fold in on itself. By definition, every triangle is convex.

e. Every triangle is convex.

Answer:

No.

Step-by-step explanation:

Solve for the first equation.

5x=25  Divide both sides by 5.

/5   /5

x=5

Solve for the second equation.

x+10=20  Subtract 10 from both sides.

  -10 -10

x=10

5 does not equal 10, so the equations are not equivalent.

Answer:

104/173

Step-by-step explanation:

173 total

Africa= 37

Asia=17

15 in BOTH

173-69=104

104 mammals are NOT found in either

104/173

Answer:

Probability = Favorable outcomes / Total outcomes

=> (Total - (Africa + Asia + Both)) / Total

=> (173 - (37 + 17 + 15)) / 173

=> (173 - 69) / 173

=> 104 / 173

Therefore, the probability = 104 / 173

Answer: Every box has the number 7 inside

The equation y = 7 at the top means that y is 7 no matter what x is

There are no x variables in the given equation, so x does not affect the value of y.

The equation y = 7 is the same as y = 0x+7. Note how plugging in any x value leads to the 0x term being 0, and adding 0 to anything doesn't change that value.

The graph of y = 7 or y = 0x+7 is a flat horizontal line through 7 on the y axis. Two points on this line are (0,7) and (1,7). Every point on this line has a y coordinate of 7.

[tex]y= -2+\frac{2}{3}x[/tex]

Step-by-step explanation:

Multiply both sides by 2

2x=3y+6

Move variable to the left-hand side and change its sing

-3y=6-2x

Divide both sides of the equation by -3

[tex]y= -2+\frac{2}{3}x[/tex]

Answer: y=3x-3

Step-by-step explanation:

Alright, so....

6x-2y=6 needs to be in slope-intercept form.

We know that y=mx+b is slope intercept form equation.

Let’s start by doing -6x and bring it to the other side.

Now we have:

-2y=-6x+6

Divide everything by -2, so it becomes:

(the computer won't do fractions so when you see this 5 it means fraction/division                                                                  9)

Answer:

6

Step-by-step explanation:

When dividing fractions, you want to multiply the reciprocal of the fraction (flip the fraction so the numerator is the denominator and the denominator is the numerator).

[tex]4*\frac{12}{8}[/tex]

If you don't know how to multiply fractions as well, I will show you now.

Since 4 is just 4/1, I will convert just so you can visually see how I multiply.

[tex]\frac{4}{1} * \frac{12}{8}[/tex]

When multiplying fractions, you multiply the numerators and the denominators.

So it would be 4 * 12 & 1 * 8

[tex]\frac{4}{1} * \frac{12}{8} = \frac{48}{8}[/tex]

Your fraction is 48/8. But it can be simplified, let's divide 48/8. That equals 6!

The required answer is 6 when 4 divided by 8/12 is equal to 6.

The division operation is given as follows:

4 ÷ (8/12)

To divide by a fraction, you can multiply by its reciprocal.

In this case, you want to divide 4 by 8/12. To do this, you can multiply 4 by the reciprocal of 8/12, which is 12/8.

So, the division can be rewritten as:

4 x (12/8)

Now, simplify the expression by multiplying:

(4 x 12) / 8

48 / 8

⇒ 4 ÷ (8/12) = 6

The final result is 6.

Therefore, 4 divided by 8/12 is equal to 6.
