Safie can write a minimum of 5 questions per hour and a maximum of 11 questions per hour.

To write 275 she takes a maximum of 275/5=55 hours and a minimum of 275/11=25 hours.

The difference is 55 hours - 25 hours = 30 hours

Answer: y = 1/2x + 8

Step-by-step explanation:

Step-by-step explanation:

To convert from gallons to quarts, multiply the gallon value by the conversion factor. For example, if converting from US fluid gallon to US fluid quart, then multiply the gallon value by 4. For example, to find out how many quarts in a half gallon of water, multiply 4 by 0.5, that makes 2 quarts in a half gallon.

Just as a plane figure can have mirror lines of symmetry, so can a solid have mirror planes of symmetry dividing it into mirror-image halves. Thus, a cuboid has three planes of symmetry dividing it into two halves.

Answer:

9%

Step-by-step explanation:

The percentage of the yearly labour cost for the parking staff is 9%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that if the total labour cost is $865,000 and $78,000 is for parking attendants.

The percentage of the yearly labour cost for the parking staff is calculated below:-

Percentage = 78000 / 865000

Percentage = 0.09 x 100

Percentage = 9%

Therefore, the percentage of the yearly labour cost for the parking staff is 9%.

Answer:

Eudora spent 0.5 hours from home to library and 1.5 hours from library to school

Step-by-step explanation:

Given

Home to Library:

[tex]S_1 = 12km/h[/tex] -- Average Speed

Library to School

[tex]S_2 = 76km/h[/tex] -- Average Speed

Total

[tex]Distance = 120km[/tex]

[tex]Time = 2\ hr[/tex]

Required

Determine the time taken from home to library and from library to school

Let the time spent from home to library  be x. So, from library to school will be: 2 - x

So, we have:

Home to Library:

[tex]S_1 = 12km/h[/tex] -- Average Speed

[tex]T_1 =x[/tex] -- Time

Library to School

[tex]S_2 = 76km/h[/tex] -- Average Speed

[tex]T_2 =2 - x[/tex] -- Time

Distance is calculated as:

[tex]Distance = Speed * Time[/tex]

Home to Library:

[tex]D_1 = S_1 * T_1[/tex]

[tex]D_1 = 12 * x[/tex]

[tex]D_1 = 12x[/tex]

Library to School:

[tex]D_2 = S_2 * T_2[/tex]

[tex]D_2 = 76 * (2- x)[/tex]

[tex]D_2 = 152- 76x[/tex]

The total distance is 120km. So, we have:

[tex]120km = D_1 + D_2[/tex]

[tex]120 = 12x + 152 - 76x[/tex]

Collect Like Terms

[tex]120 - 152 = 12x - 76x[/tex]

[tex]-32 = -64x[/tex]

[tex]-64x=-32[/tex]

Solve for x

[tex]x = \frac{-32}{-64}[/tex]

[tex]x = 0.5[/tex]

Recall that:

[tex]T_1 =x[/tex]

[tex]T_2 = 2 - x[/tex]

So, we have:

[tex]T_1 = 0.5[/tex]

[tex]T_2 = 2 -0.5 = 1.5[/tex]

Answer: 5 gallons per hour.

Step-by-step explanation: To find the unit rate, divide "gallons" by "hours." As we said, we need to find the unit rate. We want a unit rate where 1 is in denominator, so we divide the top and bottom by 6. (Remember, unit means 1.)

Step-by-step explanation:

plz make me brainliest

Answer:

80°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° by 9 to find the value of one part of the ratio

180° ÷ 9 = 20° ← value of 1 part of ratio, then

2 parts = 2 × 20° = 40°

3 parts = 3 × 20° = 60°

4 parts = 4 × 20° = 80°

The measure of the largest angle is 80°

Step-by-step explanation:

They are all integers so they are rational numbers, they are whole numbers as well except there are negative numbers so they are not all natural.

Answer:

because they are congruent to the original angle

Step-by-step explanation:

they are congruent to the original triangle. nothing will change.

The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.

The Two geometric figures should treated be congruent in the case when it should have coincided. Since the both perpendicular lines are dilated by the same factor also the same center should be used due to this, the two perpendicular lines should remain perpendicular.

Therefore, The two perpendicular lines will remain perpendicular because it should be congruent to the original angle.

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

[tex]n+(n+1)+(n+2)+78[/tex]

Solve for n. Combine like terms:

[tex]3n+3=78[/tex]

So:

[tex]3n=75[/tex]

Therefore:

[tex]n=25[/tex]

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.
