When 120 hours shared in the ratio it gives 50 hours : 70 hours
Lets add up the ratio= 5 + 7 =12
Now for 5/12 of the time = 5/12 × 120
= 50 hours
And for 7/12 of the time = 7/12 × 120
= 70 hours
What is ratio?A ratio in mathematics describes the amount of times one number is present in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 (or 3:4) for lemons (or 4:7).
The quantities in a ratio can be of any form, including counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the vast majority of situations.

Does this figure have symmetry?
E
Answer:
The letter 'E' has exactly one line of symmetry passing from it's center.
Step-by-step explanation:
We are given the letter 'E' for checking whether it have symmetry.
For that, first of all let us understand what does line of symmetry means;
A line of symmetry is a line that separates an object into two identical sections that are mirror images of one another.
Now,
The letter 'E' has exactly one line of symmetry passing from it's center.
Furthermore, just like the letter 'E' various other letters also have exactly one line of symmetry.
For example, Letter A, B, C, D, E, K, M, have exactly 1 line of symmetry.

Find the volume and surface area.
Answer: Formula used for pyramid is (V= 1/3 Bh SA: 1/2 P*l+B) Final answer is SA=110.4 V=64
Step-by-step explanation:
P= Perimeter
l= length
B= Base
To find the perimeter you add all the sides of the base. (4+4+4+4)=16
To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse. [tex]2^{2}[/tex] + [tex]12^{2}[/tex]= [tex]x^{2}[/tex]
4+144=[tex]x^{2}[/tex]
164=[tex]x^{2}[/tex]
[tex]\sqrt{164}[/tex]=x
x=12.8
To find the base it will be l*w (4*4)=16
Then you plug it in the formula for SA which will be
SA=1/2 16*12.8+16
SA=110.4
For Volume, it will be
V=1/3 Bh
V= 1/3 16(12)
V= 64
Solve −4m + 5 + 2m = 3 – 4m.
Answer:
m= -1
Step-by-step explanation:
-4m+5+2m = 3-4m
=> -4m+2m+4m = 3-5
=> 2m = -2
=> m = -2/2 = -1
Answer:
m = -1
Step-by-step explanation:
-4m + 5 + 2m = 3 - 4m
Add up light terms
-2m + 5 = 3 - 4m
Subtract 3 from both sides.
-2m + 2 = -4m
Add 2 to both sides.
2 = -2m
Divide both by -2
Final Answer: m = -1

−5(−x−1)+4x−1= 49 solve for x
Answer:
x = 5
Step-by-step explanation:
Solve for x:
-1 - 5 (-x - 1) + 4 x = 49
-5 (-x - 1) = 5 x + 5:
(5 x + 5) + 4 x - 1 = 49
Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):
((5 x + 4 x) + (-1 + 5)) = 49
5 x + 4 x = 9 x:
9 x + (-1 + 5) = 49
5 - 1 = 4:
9 x + 4 = 49
Subtract 4 from both sides:
9 x + (4 - 4) = 49 - 4
4 - 4 = 0:
9 x = 49 - 4
49 - 4 = 45:
9 x = 45
Divide both sides of 9 x = 45 by 9:
(9 x)/9 = 45/9
9/9 = 1:
x = 45/9
The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:

Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
You would use the Pythagorean Theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
The a and b is the legs and the c is the hypotenuse
So when you fill it in you get [tex]2^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]
continue to solve the equation 4+25= [tex]c^{2}[/tex]
29 = [tex]c^{2}[/tex]
then you would square root it
c = [tex]\sqrt{29}[/tex]

Answer:
18
Step-by-step explanation:
116-98
so sorry if its incorrect
Answer:
34 degrees
Step-by-step explanation:
ahahah okay this is fun
so what you should do here is extend the line that passes through the 116 and 98 degree angle so that it passes the other parallel line.
It makes a triangle doesn't it
One of the angles is supplementary to 98, so 180-98 = 82 degrees.
Another one of the angles is the opposite angle to the supplementary angle of 116 (remember your line-intersecting-parallel-lines angles), therefore 180-116 = 64 degrees
The last angle of that triangle is the opposite to angle 4, and you can find that using the other two angles of the triangle we made earlier, which you get 180-82-64 = 34 degrees

state whether each expression is meaningful. if not, explain why. if so, state whether it is a vector or a scalar.
The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product so options (b), (d), and (e) are not meaningful.
What is a vector?An item with both magnitude and direction is referred to be a vector.
A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.
A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.
The dot product of two vectors gives scalar quantity while the cross product gives a vector quantity.
Now,
In option (B) ;
a Х (b . c) now here b . c is a scalar quantity and we can not cross multiply a scalar with a vector.
In option (D) ;
(a.b) Χ (c.d) where we cannot multiply two scalars by cross product.
In option (E);
a.(b.c) we can not multiply two scalars by the dot product.
Hence "The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product".

Answer:
B = 2
Step-by-step explanation:
I used Desmos to get a visual representation to help.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).
Hope this helps!
The value of B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.
What is an equation?
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).
Therefore the value of B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.
