Answers

Answer 1

Answer: Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units

Kara answered 10% of the 40 questions on a Chinese test incorrectly. How many questions did Kara answer correctly?

Answers

Always read the question very carefully as it contains a lot of vital information's. Based on those information's the answer to the question can be easily deduced.
Total number of questions given in a Chinese test = 40
Percentage of questions incorrectly answered by Kara = 10%
Then
Number of questions incorrectly answered by Kara = (10/100) * 40
= 4
Then
The total number of questions correctly answered by Kara = 40 - 4
= 36
From the above deduction we can clearly see that Kara answered 36 questions correctly among the total of 40 Chinese questions that were given.

The answer to your problem is 36, you take 40 tiems 010 then subtract that and you get 36.

Determine the slope and intercepts for the line 2x+3y=6

Answers

Answer:

slope is -2/3 and y-intercept is 2

Step-by-step explanation:

First, solve for y.

2x + 3y = 6 subtract 2x from both side

3y = 6 - 2x divide 3 on both side

y = (6 - 2x)/3 simplify

y = 2 - (2/3)x rearrange the values

y = -(2/3)x + 2

The formula come in the general form of

y = mx + b

where m is the slope and b is the y-intercept.

y = mx + b

y = -(2/3)x + 2

in your case, m=-2/3 and b=2

so the slope is -2/3 and y-intercept is 2

A scale for a scale drawing is 10cm:1mm. which is larger the actual object or drawing explain

Answers

If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!
