191.007+0.8215

Answers

Answer:

191.829

Step-by-step explanation:

191.007+0.8215=191.8285. But since you want to round it to the nearest thousandths place, you have 191.829

Answer:

191.8290

Step-by-step explanation:

191.007 + 0.8215 = 191.8290

     

0.8215

0.0097

+______

0.8285

then add 191. to .8285, creating 191.8285, then rounding to the nearest thousandths, and in this case the thousandths is a 5, which means we always round up. That gives us 191.8290.

A triangular garden has sides that measure 6 1/4 feet, 7 1/2 feet, and 6 5/6 feet.
What is the perimeter of the garden?

Answers

Answer:

20 feet 7 inches

Step-by-step explanation:

We can separate the fractions and wholes for the minute. 6+7+6= 19

Then we can go on to the fractions a foot is 12 inches. We are given the fractions 1/4, 1/2, &5/6.

1/4 of 12 is 3 as 12 divided by 4 is 3. (3 inches)

1/2 of 12 is 6 as 12 divided by 2 is 6 . ( 6inches)

5/6 of 12 is 10 as 12 divided by 6 then multiplied by 5 is 10. (10 inches)

Because it'd be a bit weird to provide the answer 9 feet and 19 inches we have to convert the 19 inches from the fractions to feet. Since one foot is 12 inches we know that we can take one foot from the 19 inches from the fractions provided with 7 inches left. With that, the final answer is 10 feet and 7 inches.

Reynaldo drew square EFGH. Then, he drew the image of it, square E'F'G'H', 4 centimeters to the left of the original figure. Line segment EF is 6 centimeters. How long is segment E'F'?

Answers

Answer:

6 centimeters

Step-by-step explanation:

Square E'F'G'H' is just square EFGH translated to the left.

It is still the same size, just in a different location.

Line segment EF is the same length as segment E'F'.

6 centimeters

The segment [tex]E'F'[/tex] is 6 centimeters long.

According to this question, Reynaldo created a new square with same dimensions of the former one by translating it 4 centimeters to the left, which means that line segments EF and E'F' have the same length. Let suppose that no further operations have been done.

If [tex]EF = 6\,cm[/tex], then [tex]E'F' = 6\,cm[/tex] because of translation. In other words, the segment [tex]E'F'[/tex] is 6 centimeters long.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 70N acts on a certain object, the acceleration of the object is 7 m/s^2. If the force is changed to 80N , what will be the acceleration of the object?

Answers

Answer:

8 m/s²

Step-by-step explanation:

[tex]F=m*a\\\\70=m*7 \longrightarrow\ m=10 (kg)\\\\80=10*a\longrightarrow\ a=\frac{80}{10}=8(m/s^2)\\[/tex]

Answer:

Acceleration is 8 m/s²

Step-by-step explanation:

Force = mass × acceleration

[tex]{ \sf{F = m \times a}} \\ { \sf{70 = m \times 7}} \\ { \sf{m = 10 \: kg}}[/tex]

» mass is 10 kg

when force is 80N:

Answer:

The correct answer is A.

Step-by-step explanation:

sin t sin 3t sin 5t = 1/4(-sin t + sin 3t +sin 7t - sin 9t).​

Answers

Recall that

cos(a + b) = cos(a) cos(b) - sin(a) sin(b)

cos(a - b) = cos(a) cos(b) + sin(a) sin(b)

and by subtracting the first equation from the second, we get

cos(a - b) - cos(a + b) = 2 sin(a) sin(b)

So, we can write

sin(t) sin(3t) = 1/2 (cos(2t) - cos(4t))

and expanding the left side in the original equation gives

sin(t) sin(3t) sin(5t) = 1/2 (cos(2t) - cos(4t)) sin(5t)

… = 1/2 cos(2t) sin(5t) - 1/2 cos(4t) sin(5t)

Similarly, recall that

sin(a + b) = sin(a) cos(b) + cos(a) sin(b)

sin(a - b) = sin(a) cos(b) - cos(a) sin(b)

===>   sin(a + b) + sin(a - b) = 2 sin(a) cos(b)

Then

cos(2t) sin(5t) = 1/2 (sin(7t) + sin(3t))

and

cos(4t) sin(5t) = 1/2 (sin(9t) + sin(t))

So we have

sin(t) sin(3t) sin(5t) = 1/2 cos(2t) sin(5t) - 1/2 cos(4t) sin(5t)

… = 1/2 (1/2 (sin(7t) + sin(3t))) - 1/2 (1/2 (sin(9t) + sin(t)))

… = 1/4 sin(7t) + 1/4 sin(3t) - 1/4 sin(9t) - 1/4 sin(t)

… = 1/4 (-sin(t) + sin(3t) + sin(7t) - sin(9t))

as required.
