​What is the best estimate for this sum?

1/4+2/7


The sum will be close to 1/4.

The sum will be close to 1/2.

The sum will be close to 1.

Answers

Answer 1

Answer:

The sum is close to 1/2

Step-by-step explanation:

1/4 = 7/28
2/7 = 8/28
7/28 + 8/28 = 15/28

14/28 = 1/2 and 15/28 is close to 14/28

Answer 2
The best estimate for this sum is 1/2

This is because because if we make the expression into a decimal it would be 0.53571428.. and many other numbers. If you make 1/4 into a decimal it will be 0.25 which is not close to the other number. Where-as if we made 1/2 into a decimal it would be 0.5 which would be the closest. Hope this helps

Answers

Answer:

11 cm

Step-by-step explanation:

I could be wrong since I am a bit confused.

I think that the 2cm is referring to the area of the top part of the figure, and I was told the other measures are 3cm, 3cm, and 3cm.

With that knowledge, I will multiply 3cm by 3cm to get 9cm

9cm + 2cm = 11cm

A truck delivers tables and chairs for a fair. The truck can carry 1000 pounds total.
-Tables weigh 50 pounds each
-Chairs weigh 10 pounds each

Use the above information to write an equations for the number of tables, t, and the number of chairs, c, that the truck can carry.

Answers

50t+10c less than it equal to 1000

The required expression is given as 50t + 10c = 1000.

Given that,
A truck delivers tables and chairs for a fair. The truck can carry 1000 pounds in total.

-Tables weigh 50 pounds each

-Chairs weigh 10 pounds each

What is the equation?

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
Let the number of tables, t, and the number of chairs, c, that the truck can carry,
Now,
Total weight of T table = 50t
Total weight of c table = 10c
Total weight truck Carry = 1000
50t + 10c = 1000

Thus, the required expression is given as 50t + 10c = 1000.

Kendra has a painting canvas that is 22 inches wide by 38 inches high. She painted a red rose, which covered 30% of the canvas.

What was the area of the canvas which was covered by the red rose

Answers

Given:

Breadth of canvas is 22 inches. Length of canvas is 38 inches.

To Find:

If kendra covered 30% of the canvas by painting red rose, what will be the area of canvas covered by red rose?

Solution:

To find the area of red rose, first we have to find the area of canvas.

★ Area of Rectangle = Length × Breadth

➝ 22 × 38

➝ 836 in²

So, Area of canvas is 836 inches².

★ Area of red rose:-

➝ 30% of 836 in²

➝ 0.30 of 836

➝ 250.8

Hence, Area covered by the red rose is 250.8

____________________Additional Information:

★ Triangle => ½bh

★ Rectangle => Length × Breadth

★ Circle => πr²

★ Square => Side × Side

★ Parallelogram => Base × Height
