Answer:
is there an equation we are suppose to use?
Step-by-step explanation:
Add and round the answer to the nearest THOUSANDTHS place value
191.007+0.8215
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.
p.s. there's no need for the zero at the end

Solve the system of equations using substitution or elimination:
x = 3y + 6
2x - 4y = 8
Answer:
x=0, y=-2
Step-by-step explanation:
Let x=3y+6 be equation 1
and 2x-4y=8 be equation 2
sub equation 1 into equation2,
2(3y+6)-4y=8
6y+12-4y=8
2y=-4
y=-2
sub y=-2 into equation 1,
x=3(-2)+6
x=0
sub is an abbreviation for substitute

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?
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.

Step-by-step explanation:
The perimeter of this garden is the sum of the lengths of its three sides:

This could and should be rounded off to 2 decimal places: 20.58 ft

You are making a smoothie that calls for 1/4 cup of yogurt. This only makes enough for 1 person and we need enough for 6 total people. How much
yogurt should you add
Answer:
Step-by-step explanation:
1 2/4
Well an easy way to solve this would be multiply it by 6. 1*6=6 and 4*6=24.
That would be enough for 6 people. Or you could do. 1/4+1/4+1/4+1/4+1/4+1/4 and get the same answer.

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'?
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.
We kindly invite you to check this question related to translation of squares: https://brainly.com/question/12891664
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?
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:
[tex]{ \sf{F = m \times a}} \\ { \sf{80 = 10 \times a}} \\ { \sf{a = \frac{80}{10} }} \\ \\ { \sf{a = 8 \: {ms}^{ - 2} }}[/tex]

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).
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.
