Answer:

27 miles per gallons

Step-by-step explanation:

Take the number of miles and divide by the number of gallons

297 miles / 11 gallons

27 miles per gallons

I'm not sure it its prob D

It's in p/q form where p = 16 and q = 33.

=======================================================

Work Shown:

x = 0.484848.....

100x = 48.4848.....

I multiplied both sides by 100 to move the decimal over 2 spots. Both decimal values for x and 100x have an infinite string of "48"s repeated after the decimal point. When we subtract, those infinite strings will cancel out

100x - x = 99x

48.4848..... - 0.484848..... = 48

So after subtracting straight down, we have the new equation 99x = 48 which solves to x = 48/99

Divide both parts by the GCF 3 to fully reduce

48/3 = 16

99/3 = 33

Therefore, x = 48/99 = 16/33 = 0.484848...

I recommend using a calculator to confirm that 16/33 = 0.484848...

Side note: your calculator may round the last digit, but this is of course rounding error

Answer: The distance left after 20 days is 1350 miles

Step-by-step explanation:

To calculate the distance, we use the formula:

[tex]s=\frac{d}{t}[/tex]

where,

s = speed of the bicycle = 90 miles/day

t = time taken = 20 days

d = distance travelled = ? miles

Putting values in above equation, we get:

[tex]d=(90miles/day\times 20days)=1800 miles[/tex]

Total distance to the destination = 3150 miles

Distance travalled in 20 days = 1800 miles

Distance left after 20 days = [3150 - 1800] = 1350 miles

Hence, the distance left after 20 days is 1350 miles

===========================================================

Explanation:

The angle adjacent and supplementary to the 107 degree angle is 73 degrees because 107+73 = 180.

Or you could say 180 - 107 = 73.

The base angles of the upper isosceles triangle are 73 degrees each, which means the third remaining angle (let's call it y for now) is

73+73+y = 180

146+y = 180

y = 180-146

y = 34

Refer to the diagram below. Notice how the 34 degree angle shows up twice because we have vertical angles. Consequently, the base angles of the bottom isosceles triangle are y = 34 degrees each

We can now solve for x

y+y+x = 180

34+34+x = 180

68+x = 180

x = 180-68

x = 112, so the answer is choice D

Answer:

B

Step-by-step explanation:

Let the number = x

2/5 (x - 1)

<

3/5 (x + 1)

2/5 (x - 1 ) < 3/5(x+ 1)      Multiply both sides  by 5

2(x - 1) < 3 ( x + 1)            Remove the brackets.

2x - 2 < 3x + 3                Add 2 to both sides

2x < 3x + 5                     Subtract 3x from both sides

2x - 3x < 5              

- x < 5                            Here's the tricky part . Divide by - 1

x > -5                             Notice what happened. The < become > That happens because you have divided (or multiplied) by a negative number.

The original question 2/5 (x - 1 ) < 3/5(x+ 1)    was graphed. The red part is every value that satisfies the inequality. You should be using a y and x together to find a more suitable answer using this program. But if you just look along the x axis, you will see that the < has been turned around.

Answer:

4. m<7 = m<3 + m<2

Step-by-step explanation:

Recall: the exterior angle theorem of a triangle states that an exterior angle is equal to the sum of the two opposite interior angles of a triangle.

❌Option 1 CANNOT be true

Rationale:

m<1 is an exterior angle of triangle ∆ABC and ∆EBC, so based on the exterior angle theorem of a triangle, m<1 = m<3 + m<4 or m<1 = m<ABC + m<5

❌Option 2 CANNOT be true.

Rationale:

m<5 ≠ m<3 - m<2

❌Option 3 CANNOT be true.

Rationale:

m<6 ≠ m<3 - m<2

✅Option 4 is CORRECT.

Rationale:

Based on the external angle theorem of a triangle,

m<7 = m<3 + m<2

Answer: the required answer is 1320

Step-by-step explanation:

Total people = 12

Different phone lines = 3

We will choose the person to answer the first phone in 12 ways.

Then choose the second person in 11 ways. (11 people left)

Then choose the third person in 10 ways.  ( 10 people left)

The number of groups of 3 people can answer these lines[tex]12 \times11\times10=1320[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

With 35 internal nodes, there are 5*35=175 vertices out of which are 175-35=140 leaves.

The number of vertices in a full 5-ary tree is 175.

The number of leaves is 140.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of full trees = 5

Number of internal vertices = 35

Now,

The number of vertices.

= 5 x 35

= 175

Now,

The number of leaves.

= 175 - 35

= 140

Thus,

Number of vertices is 175.

Number of leaves is 140.
