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

(x-3)/(-3) = 27 /3 - x
Answer:
X= 12
Step-by-step explanation:
Divide 27/3= 9
Multiply 3 from both sides: x-3/-3 * 3 = 9 *3- x * 3
Simplify: -(x-3) =27-x*3
2x=24
Divide 2 from both sides: 2x/2= 24/2
x=12
Solve for x please will mark brainliest

k=57
Opposite angles are equal

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.

The perimeter of this garden is the sum of the lengths of its three sides:

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
if there are two containers of sugar solution, the first is 4% concentration and second is 8% concentration. how much of each should we combine to get 40 gallons of 5% concentrate solution
Answer:
30 gallons solution 4% and 10 gallons solution 8%
Step-by-step explanation:
x•4%+y•8%=40•5%4x+8y=40•5 and x+y=40
x=40-y
4(40-y)+8y=200
160-4y+8y=200
4y=200-160
4y=40 => y=10 (gallons solution 8%)
=> x=40-10=30 (gallons solution 4%)
30 gallons solution 4% and 10 gallons solution 8%

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]

Two cars leave towns 760 kilometers apart at the same time and travel toward each other. One car's rate is 20 kilometers per hour less than the other's. If they meet in 4 hours, what is the rate of the slower car?
Answer:
Let speed of slower car be xkm/h
Therefore rate of other car=x+20 km/h
After 4 hrs ,
Distance covered by Car A=4x
Distance covered by Car B=4x+80
4x+4x+80=760km
8x=680
x=45
The rate of the slower car=45km/h

Answer:
c
Step-by-step explanation:
Option c is correct. All points are equally spaced from the line x=1 as their images do. They are symmetric about the line x=1. For instance, point A and A' are both 3 units from the line x=1.
Option a and B are wrong as we cannot see and swapping of x and y coordinates to a point.
For option d, only point A is shifted 6 units to the left to A', but point B shifted 8 units to B'. Incorrect.

What is the equation of the line that passes through the point (-2,5) and has a
slope of -4?
Answer:
[tex]\boxed {\boxed {\sf y= -4x -3}}[/tex]
Step-by-step explanation:
We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.
[tex]y-y_1= m(x-x_1)[/tex]
In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).
m= -4 x₁= -2 y₁ = 5Substitute the values into the formula.
[tex]y-5 = -4 (x--2)[/tex]
[tex]y-5 = -4 (x+2)[/tex]
We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.
First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.
[tex]y-5=( -4 *x ) + (-4* 2 )[/tex]
[tex]y-5 =(-4x)+ (-8)\\y-5= -4x -8[/tex]
5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.
[tex]y-5 =-4x -8 + 5[/tex]
[tex]y= -4x -3[/tex]
The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.
