Start with the equation 5 • 0 = 0 to explain why 5 • -2 must equal -10. Drag descriptions and equations to the table to complete

lorasvet [3.4K]

Answer:

Step-by-step explanation:

1. The problem is telling us to start with the equation 5*0=0

2. Substitute. Any number plus its opposite is zero. Since the opposite of 10 is -10, 10+(-10)= 0: 5(10+-10)=0

3. 3 Use the distributive property. In other words multiply 5 by 10 and 5 by -10: 4·10+5·-10=0

4. Multiply. perform the first multiplication of step 4: 5·10=50, so: 50+4·-10=0

5. Subtract 50 from both sides. 50-50+5·-10=0-50; simplify the left side: 0+5·-10=0-40

5·-10=0-50

6. Simplify to solve for 5·-10. Simplify the right side: 5·-10=-50

____________________________________________________________

Given. 5·0=0

Step 2 Substitute. Any number plus its opposite is zero. 5(10+-10)=0

Step 3 Use the distributive property. 5·10+5·-10=0

Step 4 Multiply. 40+4·-10=0

Step 5 Subtract 40 from both sides. 5·-10=0-50

Step 5 Simplify to solve for 4·-10. 5·-10=-50

a water wheel has a radius of 18 feet. The wheel is rotating at 10 revolutions per minute. Find the linear speed, in feet per

Yuri [45]

Answer:

The linear speed is $1,130.4\frac{ft}{min}$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=18\ ft$

$\pi =3.14$

substitute

$C=2(3.14)(18)$

$C=113.04\ ft$

step 2

Find the linear speed in feet per minute

we know that

The wheel is rotating at 10 revolutions per minute

Convert revolutions to feet

Remember that

One revolution is equal to the circumference of the circle

10 revolutions is equal to

$(10)113.04=1,130.4\ ft$

therefore

The linear speed is $1,130.4\frac{ft}{min}$
