What is the value of X? SOMEONE PLEASE HELP!! - 1

Answers

Answer 1
Answer:

Remember, one whole circle is 360 degrees. This means that the side that looks to be the same as 43 degrees is 43 degrees. The side that looks the same as (6x+5) should be (6x+5).

Now just set up your equation like this and solve:

43+43+6x+5+6x+5=360

Hope I could be of help! :)

5 schools sent some students to a conference.One of the schools sent both boys and girls.
This school sent 16 boys.
The ratio of the number of boys it sent to the number of girls it sent was 1 : 2

The other 4 schools sent only girls.
Each of the 5 schools sent the same number of students.

Work out the total number of students sent to the conference by these 5 schools.

Answers

Call the first school "School A." Call the rest of the schools "School B, School C, School D, and school E." 

The ratio of boys to girls in school A is 1:2. Therefore: 

(1)/(2)=(16)/(x) 

Solving for x in that equation gives us 32 girls. Therefore, School A sent 48 kids in all. 

School B - E have the same numbers. Therefore, the number of students sent to the conference is 48 x 5. Therefore, 240 kids attended the conference.

Hope that helped!

When the numerator and denominator have only 1 as a common factor

Answers

then it is in simplest form and they are both prime
A fraction in which the greatest common factor of the numerator and the denominator is 1 is known as a reduced, or simplified, fraction. Quite often I have also heard this called a fraction in its lowest terms. This just means that the fraction has been reduced

A function f (x)=-8x^2. What is f (-3)?

Answers

f(x) = -8x²

To find the value of f(-3), put -3 in place of 'x' in the definition of the function.

f(-3) = -8(-3)²

f(-3) = -8(9) = -72
f(x)= -8x²

f(-3)= -8* (-3)²

f(-3)= -8 * 9

f(-3)= -72

T=Pri for t, if i=105, P=700, and r=0.005

Answers

If the numbers are played next to each other (like Pri) then they are multiplied together. So you'd do:
Pri = (700)(0.005)(105) = 700 x 0.005 x 105
= 367.5
