A Square Has A Diagonal That Is 36 Mm Long. What Is The Area Of The Square?If Necessary, Round Your Answer

Answers

Answer 1

Answer:

18mm

Step-by-step explanation:

in the triangle we will say:

36=x^2 +x^2

36=2x^2

so x will be = root 18

as the area = x*x

so root 18 * root18=18mm^2

What is the equation of the line —3x – 2y = 30 in slope-intercept form?

Answers

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 3x - 2y = 30 ( add 3x to both sides )

- 2y = 3x + 30 ( divide terms by - 2 )

y = - [tex]\frac{3}{2}[/tex] x - 15 ← in slope- intercept form

(a) 85% of 80 is what number?
(b) 21 is 35% of what?

Answers

Answer:

a) 68

b)60

Step-by-step explanation:

a) 85% = 0.85

0.85 * 80 = 68

b) let x be the unknown number.

35% = 0.35

0.35x = 21

x = 60

Answer:

Step-by-step explanation:

a, 85% of 80

85% of 80

= 85/100*80

=85/100*80

=0.85*80

=68.

b, 21 is 35%

21 is 35%

=21*35/100

=21*0.35

=7.35.

I really need help finding the solution!!

Answers

Answer:

-0.5 is not a solution

2 is a solution

Step-by-step explanation:

To check if something is a solution of the equation, you need to substitute the value in place of the variable

15 + 2y = -12 - 4y

15 + 2(-0.5) = -12 - 4(-0.5)

15 - 1 = -12 + 2

14 ≠ -10 ∴ -0.5 is not a solution

5 - 2(3x + 5) = 3 - 10x

5 - 2[3(2) + 5] = 3 - 10(2)

5 - 2(6 + 5) = 3 - 10(2)

5 - 12 - 10 = 3 - 120

-17 = -17 ∴ 2 is a solution

Use the information given to write an equation in standard form.

6. Slope is 3, and (1. 4) is on the line.

7. Slope is -2, and (4,3) is on the line.

10. Slope is , and (1, 3) is on the line.

11. Slope - , and (2, 3) is on the line

Answers

The correct answers are:

6. 3x-y=-1

In slope intercept form this equation has a slope of 3 and point 1,4 is included on the graphed line: y=3x+1 is slope intercept form.

7. 2x+y=11

In slope intercept form this equation has a slope of -2 and point 4,3 is included on the graphed line: y=-2x+11 is slope intercept form

10. 4x-7y=-17

In slope intercept form this equation has a slope of 4/7 and point 1,3 is included on the graphed line: y=4/7x+17/7 is slope intercept form


11. 3x+2y=12

In slope intercept form this equation has a slope of -3/2 and point 2,3 is included on the graphed line: y=-3/2x+6 is slope intercept form


You basically just find the slope intercept form of each question then convert the intercept form over to standard form then graph in intercept form to see if the point lies on the line :)
