This is calculated as:

1/ number of hours for Renee + 1/ number of hours for Geneva = 1/ Total number of hours that they can do it together

= 1/16 + 1/12 = 1/T

Lowest common denominator = 192

The area of the rectangle is 40 cm.
To find this, just multiply 8 and 5.
Area: length times width
Area: 8 times 5
Area: 40 cm

The perimeter of the rectangle is 26 cm.
Perimeter: 2L + 2W
Perimeter: 2(8) + 2(5)
Perimeter: 16 + 10
Perimeter: 26
Hope this helps!

Answer:

Area is 40

perimeter is 26

Step-by-step explanation:

area = l×w

[tex]8 \times 5 = 40[/tex]

Perimeter = 2L +2W

Step-by-step explanation:

Circumference=

The circumference of the circular base of the object is 4.082 in

What is circumference?

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center.

Given that, we need to find the circumference of the circular base of the object, whose radius is 0.5 in

The circular object is referred as circle, the circle's circumference is its boundary length measured in unit whose power is always 1, like m, cm, km etc.

Here, if we calculate the circumference of the object, we will get,

The circumference of any circular object given by :-

C = 2π×radius

C = 2×3.14×0.65 = 4.082 in

Hence, the circumference of the circular base of the object is 4.082 in

Hopes this helps:

Answer: u = 4

1. Expand.
9u - 6 = 6u + 6

2. Add 6 to both sides.
9u = 6u + 6 + 6

3. Simplify 6u + 6 + 6 to 6u + 12.
9u = 6u + 12

4. Subtract 6u from both sides.
9u - 6u = 12

5. Simplify 9u - 6u to 3u.
3u = 12

6. Divide both sides by 3.
u = 12/3

7. Simplify 12/3 to 4.
u = 4

Ewok's favorite candy is a gummy

inches long: How many gummy

inches

Answers

Answer:

3.5

Step-by-step explanation:

45 inches divided by 13 inches

gets you 3.4615 but i think you should round up so 3 and a half

Well, if you round the the answer is about 3.5 gummy worms.

This is because 45 divided by 13 equals 3.46153846. That is a VERY long number so you obviously round to the nearest tenth which gives you 3.5. So in the end you would need about 3 and a 1/2 gummy worms to lay them end to end and have a total length of 45 inches. I hope this helps!! (Also that is one really big gummy worm. 13 INCHES??

which statement describes the effect on the parabola y= x^2 -1 when its is changed to y =x^2 +6?

Answers

The effect on the parabola y = x^2 - 1 when it is changed to y = x^2 + 6 is a translation of 7 units upwards.

What is the effect on the parabola?

First let's do an introduction, for any function f(x), we can define a vertical translation of N units as:

g(x) =f(x) + N

Where if N > 0, the translation is upwards, and if N < 0, the translation is downwards.

In this case, we start with the parabola:

y = f(x) = x^2 - 1

Now we know that the transformed function is:

y = g(x) = x^2 + 6

Now, notice that if we apply a translation upwards of 7 units of the original function we will get:

y = f(x) = x^2 - 1 + 7 = x^2 + 6

We got the transformed function.

Then the effect on the parabola is a translation of 7 units upwards.

Kayla and Mario are playing with a football at the park on a windy day. Mark throws the football straight up in the air, and a gust of wind blows it 10 feet west and 4 feet south from Mark. If [x y] represents the original location of the football, write a matrix that represents the location of the translated ball.

Answers

Answer:

|x-10 y-4|

Step-by-step explanation:

Let the initial position where the football is thrown up the air be x and y.

After the ball is thrown up the air it moves 10 feet west 4 feet south because of the gust of wind.

Therefore the change in x is by 10 feet west and is at the point x - 10 and the change in y is by 4 feet south and is at the point y - 4.

Thus the matrix representing the position of the football is |x-10 y-4|.

GOT IT RIGHT ON EDGE

The true statement about the histogram are

(a) the median and the mean are approximately equal(d) the histogram would have an approximately normal curve(e) there are more data elements between 6 and 9.

How to interpret the histogram?

The dataset is given as:

5.5, 6, 7, 10, 7.5, 8, 9.5, 9, 8.5, 8, 7, 7.5, 6, 6.5, 5.5

Using a statistical calculator, we have the following summary:

Mean = 7.43

Median = 7.5

Notice that the median and the mean are approximately equal

i.e. 7.43 ≈ 7.5

When the mean and the median are equal, the histogram would have an approximately normal curve

Also, when the dataset is sorted, we have:

5.5, 5.5, 6, 6, 6.5, 7, 7, 7.5, 7.5, 8, 8, 8.5, 9, 9.5, 10

Notice that there are more data elements between 6 and 9.

Hence, the true statement about the histogram are (a), (d) and (e)
