Answer:
5 9/20
Step-by-step explanation:
4 7/10 + 6/8
Simplify the fractions by dividing the second top and bottom by 2
4 7/10 + 3/4
Getting a common denominator of 20
4 7/10 *2/2 + 3/4 * 5/5
4 14/20 + 15/20
4 29/20
4 + 20/20 + 9/20
4+1+9/20
5 9/20
First, you have to find the common denominator.
It is 40.
But if we change the denominator, you have to change the numerator as well.
We multiplied 10 by 4 to get to 40, so we multiply 7 by 4.
[tex]\frac{28}{40}[/tex]
We multiplied 8 by 5 to get to 40, so we do the same to 6:
[tex]\frac{30}{40}[/tex]
Now add them:
[tex]\frac{28}{40} +\frac{30}{40}[/tex]
We get:
58/40

An insect crawls up 5cm every second on a 6cm vertical rod and then falls down 2cm over the next second. How many seconds will it take to climb the rod?
Answer:
3 seconds
Step-by-step explanation:
It's quite simple. First, add 5cm to the progress of the insect, counting it as 1 second. Then subtract 2cm because it falls over the next second, thus taking another second. Then finally, plus 5cm, making it 3 seconds. It's not 4 seconds because at 3 seconds it had already reached the top.

Mary can do a job in 80 minutes, Working with Jané, both can do the job in 30
minutes. How long will it take Jane to do the job alone?
Answer:
see below
Step-by-step explanation:
The equation to determine the work time is
1/a+1/b = 1/c where a and b are the times alone and c is the time together
1/80 + 1/30 = 1/c
Multiply by the least common denominator to clear the fractions, which is 240c
240c(1/80 + 1/30 = 1/c)
3c+8c = 240
11c = 240
Divide by 11
11c/11 =240/11
c = 240/11 minutes
c=21.81818
Approximately 22 minutes

Triangle not drawn to scale
O A. 3.5 yds
O B. 4.1 yds
C. 2.8 yds
D. 4.5 yds
Answer:
3.5 yards
Step-by-step explanation:
The value of c in the triangle ABC is 3.5 yds, Option A is correct.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle is ABC.
We have to find the length c in the triangle.
Now let us use sine rule to find the value of c.
c / sin 28° = 4 / sin 32°
The value of sin 28° is 0.4695 and sin 32° is 0.5299
c / 0.4695 = 4 / 0.5299
Apply cross multiplication
c × 0.5299 = 4 × 0.4695
c × 0.5299 = 1.8636
Divide both sides by 0.5299
c = 1.8636/0.5299
c = 3.516
= 3.5 yds
Hence, the value of c in the triangle ABC is 3.5 yds, Option A is correct.
