Write a number in which the digit 3 is ten times the value of the digit 3 in 9.431

Mathematics
1 answer:
IgorC [24]3 years ago
6 0

Answer:

Step-by-step explanation:

One number would be

9.31

The 3 in this number is 3/10

The 3 in the given number is 3/100

3/10 is 10 times bigger than 3/100

3/10 = 0.3

3/100 = 0.03

0.03 * x = 0.3                   Divide both sides by 0.03

0.03/0.03 x = 0.3/0.03

x = 10

Joyce old 218 cupcakes of lemonade at his lemonade stand. What is 218 rounded to the nearest tens
MAXImum [283]

220

from 218 the 1 is in the tens column. this is the figure that needs to be rounded.

using the following rule

If the digit after the 1 is ≥ 5 then round 1 up to 2

If the digit after the 1 is < 5 then the 1 remains as 1

here the digit after the 1 is 8 so the 1 in the ten's column becomes 2 and the 8 is replaced by 0

218 ≈ 220 ( to the nearest ten )

What values of a, b, and c would you use in the quadratic formula for the following equation? 6x^2+5x-4=0
Yanka [14]
So remember that in a quadratic equation there is a type of quadratic equation of the form ax^2+bx+c=0 so to find what values of a, b, and c you need for the quadratic formula, you need to look at your equation and label a, b, and c. In this equation a=6, b=5 and c=-4. So for the quadratic formula you would use a=6, b=5 and C=-4. I hope this helps!!!!!

What is 2/5 ÷ 4/7 equal to
olchik [2.2K]
When you have to divide a fraction, you have to invert the second fraction (4/7 becomes 7/4), and you then multiply the two fractions.

=2/5 ÷ 4/7
=2/5 * 7/4
Multiply the numerators on top
Multiply the denominators on bottom
=(2*7)/(5*4)
=14/20
Simplify by dividing 2 into top & bottom
=7/10

Hope this helps!! :)

Given the following information, determine which lines are parallel and what justifies them being parallel.
kow [346]

Answers:

Blank 1 = p and q

Blank 2 = Consecutive interior angles converse

=================================================

Explanation:

There's a lot of visual noise here, meaning there's a lot of lines and angles to potentially distract. I recommend redrawing things but only drawing lines p and q, and the transversal cut line t. Furthermore, I would mark only angle 8 and angle 13. See the diagram below.

The diagram is optional, but hopefully you can see that the angles are same side interior angles, aka consecutive interior angles. That's why we go with the consecutive interior angles converse

If we drop the "converse" portion, then that theorem says parallel lines lead to supplementary consecutive interior angles. The converse just reverses the flow of the logic.
