The circumference of circle P is 800 mm, the circumference of circle Q is 200 cm, and the circumference of circle R is 4 m. What

Lapatulllka [165]

Answer:

circle P has a circumference of 800mm which is equal to 80cm

circle Q is 200cm

circle R is 4m which is equal to 400cm

You will get the sum of the distances by placing the figures under one measurement that is meters

And so add the figures in cm(200+400+80) and get 680

Then convert this to meters and get 6.8m

Hence your answer is C

Consider the quadratic equation 2x² + 72 + k = 0. Which value of k results in the equation having complex solutions?

postnew [5]

Hi there!

$\large\boxed{k> 6.125}$

We can use discriminants to determine the value of k for which the equation would have complex solutions. (Those involving i)

If b² - 4ac < 0, then the equation will have complex solutions. Therefore:

Plug in the given values of b and a to solve:

7² - 4(2)(k) < 0

Simplify:

49 - 8k < 0

Solve the inequality:

49 < 8k

6.125 < k

k > 6.125. Anything greater than 6.125 would result in complex solutions.

Given the triangle below, which of the following is a correct statement? Right triangle ABC with AB measuring 5, AC measuring 6,

Elanso [62]

Drawing a diagram to match this figure, BC would have to be the hypotenuse as it is the longest side of the triangle. Angle A would have to be the right angle.
For the first choice, $\cot B = \frac{1}{ \tan B} 
\\ = \frac {1}{\frac {6}{5}}
\\ = 1 \div \frac{6}{5} = \frac{1}{1} \div \frac{6}{5}
\\ = \frac{1}{1} * \frac{5}{6} = \frac{5}{6}$ . The first choice is not correct.
The second choice gives us $\csc C= \frac{1}{ \sin C}= \frac{1}{\frac {5}{8}}
\\ = 1 \div \frac{5}{8} = \frac{1}{1} \div \frac{5}{8}
\\ = \frac{1}{1} * \frac{8}{5} = \frac{8}{5}$ . The second choice is not correct either.
The third choice gives us

A party planner is making gift bags for an event. He has 96 pencils,

Yuliya22 [10]

Considering the greatest common divisor, you obtain:

the greatest number of gift bags that the party planner can make is 12.
the number of each item present in each bag is 8 pencils, 3 erasers and 2 pencil toppers.

<h3>Greatest common divisor </h3>

The greatest common divisor is the largest number that exactly divides two or more numbers at the same time. That is, it is the largest number by which two or more numbers can be divided, resulting in a whole number.

A method to calculate the greatest common factor must follow the following steps:

Decompose or separate each number into prime factors.
Common factors are noted.
In each of the commons, the factor with the smallest exponent is chosen.
Multiply the chosen factors.

To find the greatest number of gift bags the party planner can make, you find the greatest common divisor.

To do this, decompose the numbers 96, 36 and 24:

96= 2⁵×3
36= 2²×3²
24= 2³×3

The common factors with the smallest exponent are: 2² and 3

So, the greatest common divisor between 96, 26 and 24 is calculated as: 2²×3= 4×3= 12

This means that the greatest number of gift bags that the party planner can make is 12.

To calculate the number of each item present in each bag, you divide the quantity of each item by the quantity of gift bags:

96 pencils÷ 12= 8 pencils
36 erasers÷ 12= 3 erasers
24 pencil toppers÷ 12= 2 pencil toppers

Finally, the number of each item present in each bag is 8 pencils, 3 erasers and 2 pencil toppers.
