What is the answer to 5×23×2

Answers

Answer 1

Answer: The answer to that is 230. 5 times 2 is 10, and 10 times a number is that number witha zero behind it. Example: 10 times 34, that equals 340.

Answer 2

Answer: 230 because 5x23=115 and x 2=230

On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the left of the line is shaded. The second dashed line has a negative slope and goes through (0, 2) and (4, 0). Everything below and to the left of the line is shaded. Which system of linear inequalities is represented by the graph? y > x – 2 and x – 2y < 4 y > x + 2 and x + 2y < 4 y > x – 2 and x + 2y < 4 y > x – 2 and x + 2y < –4

Answers

Answer:

$y\geq x-2$

$x+2y<4$

Step-by-step explanation:

step 1

Find the equation of the first inequality

Find the equation of the first solid line

we have the ordered pairs

(0,-2) and (2,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute the values

$m=(0+2)/(2-0)$

$m=(2)/(2)$

$m=1$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=1$

$b=-2$ ---> the y-intercept is given

substitute

$y=x-2$

Remember that

Everything to the left of the solid line is shaded

The inequality is

$y\geq x-2$

step 2

Find the equation of the second inequality

Find the equation of the second dashed line

we have the ordered pairs

(0,2) and (4,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute the values

$m=(0-2)/(4-0)$

$m=(-2)/(4)$

$m=-(1)/(2)$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=-(1)/(2)$

$b=2$ ---> the y-intercept is given

substitute

$y=-(1)/(2)x+2$

Remember that

Everything below and to the left of the line is shaded

The inequality is

$y<-(1)/(2)x+2$

Rewrite

Multiply by 2 both sides

$2y<-x+4$

$x+2y<4$

therefore

The system of inequalities is

$y\geq x-2$

$x+2y<4$

What are the partial products Lucas will need to solve the problem?

Answers

The partial products that Lucas would need to solve this problem would be 3,740 and 187,000 if you are multiplying 374 on the top column and 510 on the bottom column. Or, the partial products Lucas would need is 2,040 and 35,700 and 153,000. Both partial products combination added together would be 190,740.

Answer:

3,740 and 187,000

Joseph walks at a constant speed. He walked to a store that is 0.5 miles away in 6 minutes. How many miles, m, can he walk in t minutes?

Answers

Answer:

Step-by-step explanation:

if he can walk 0.5 miles in 6 minutes at a constant rate then you can say that he can walk 1 mile in 12 minutes.

therefore he can walk 1/12 mile ever one minute

so m=1/12t

πcm3. What is the radius?

Answers

Answer:

Step-by-step explanation:

The volume of a sphere is 500 3 πcm3. what is the radius? sphere v = 4 3 πr3 1. substitute value into formula: 500 3 π = 4 3 πr3 2. undo multiplication of 4 3 : 125π = πr3 3. undo multiplication of π: 125 = r3 4. undo cube: 3√125 = r the radius of the sphere is 6 ⇒ 5 cm

Answer:

about 4.9 cm

Step-by-step explanation:

The equation for the volume of a sphere is V= $(4)/(3)\pi r^3$ . So, to solve this problem we will plug in 500 for V and solve for the radius, $r$ .
