Step-by-step explanation:
Eudora ran from her home to her secret laboratory at an average speed of 12\text{ km/h}12 km/h12, start text, space, k, m, slash, h, end text. She then took one of her jetpacks and flew to her school at an average speed of 76\text{ km/h}76 km/h76, start text, space, k, m, slash, h, end text. Eudora traveled a total distance of 120120120 kilometers, and the entire trip took 222 hours. How long did Eudora spend running, and how long did she spend flying using her jetpack? Eudora ran for hours and flew for hours using her jetpack.
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]
3(10m - 2)+(3+6m-3)
Answer:
3(10m - 2)+(3+6m-3)
30m-6+3+6m-3
30n+6m-6+3-3
36m-6
6(6m-1)
Answer:
36m - 6
Step-by-step explanation:
3 ( 10m - 2 ) + ( 3 + 6m - 3 )
→ Expand the brackets
30m - 6 + 3 + 6m - 3
→ Simplify
36m - 6

jake travels 6 hours for a total of 444 miles on 20 gallons of gas, rate for gallons and hours.
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.)

Explain why two perpendicular lines will remain perpendicular if they are both dilated by the same factor
and using the same center
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.
What is congruent?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:
The difference is 30 hours
Step-by-step explanation:
Proportions
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
The measures of the angles of a triangle are in the ratio 2.3.4. What is the number of degrees in the measure of the largest angle?
Answer:
let ratios be x
2x +3x+4x=180(Sum of triangles)
x=20`
2X=20
x=20×2
X=40
3x=20
X=60
4x=20
x=80
largest angle is 80
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°

Part A
Enter an equation that can be used to represent the amount, r, Sarah spent at the restaurant.
Answer:
195 - 164 = r
Step-by-step explanation:
This is how I would solve for the amount that Sarah spent at the restaurant. She had 195 total, subtract by 164 because we know she spent that, and whatever is left she spent at the restaurant.

There are 2 gallons for every 8 quarts. If there are 12 quarts, how many gallons are there?
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.

Step-by-step explanation:
The sum of 3 consecutive integers is 78. What is the integer closest to zero?
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.
