Answer:
12
Step-by-step explanation:
Think of this as a normal calculation at first.
Just focusing on the numbers themselves (not the roots) let's do the calculation.
8 × 18 = 144
Let's put the square roots back into play.
√144
And we know what the square root of 144 is (12).

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]

What angle relationship best describes angles AFC and DFB?
A) Adjacent angles
B) Complementary angles
C) Linear pairs
D) Vertical angles
Answer:
Vertical Angles
Step-by-step
I believe this is the case because since the angles intercept in order to form also it's the only answer that has to do with intercepting from what we can see from the diagram.
There are different types of relationships between angles including alternate, corresponding, vertical, adjacent, complementary and supplementary angles
The correct option for the relationship that best describes angles AFC and DFB is option D;
D) Vertical angles
The reason the chosen option is correct is as follows;
The given diagram shows line EF perpendicular to line AB and line CD crosses line AB at point F
Therefore, the angles ∠AFC and ∠DFB formed by lines AB and CD with their orientation in the order of their names are opposite to each other and other are known as vertical angles

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.

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°

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.

Find the first five terms of the recursive sequence.
Answer:
The first five terms of the recursive sequence are;
5, 12, 19, 26, 33
Step-by-step explanation:
The given sequence is presented as follows;
aₓ = a₍ₓ ₋ ₁₎ + 7
The first term of the sequence, a₁ = 5
Therefore, we have;
a₂ = a₍₂ ₋ ₁₎ + 7 = a₁ + 7 = 5 + 7 = 12
a₃ = a₍₃ ₋ ₁₎ + 7 = a₂ + 7 = 12 + 7 = 19
a₄ = a₍₄ ₋ ₁₎ + 7 = a₃ + 7 = 19 + 7 = 26
a₅ = a₍₅ ₋ ₁₎ + 7 = a₄ + 7 = 26 + 7 = 33
The first five terms of the recursive sequence are therefore;
5, 12, 19, 26, 33.
