Answer:

You take the two and make the equations

x+y=8

3x+7y=36

(x=3 pounds;y=7 pounds)

then you plug numbers in.. (v)

Step-by-step explanation:

3(5)+7(3)=36

15+21=36

<h2>So you have 5, 3 pound sacks, and 3, 7 pound sacks <--ANSWER</h2>

A line has a slope of 9 and passes through the point (0, 5). What is its equation in slope -intercept form?
Sedbober [7]

Answer:

y = 9x + 5

Step-by-step explanation:

Slope = m = 9

(0 , 5)

Slope intercept form: y = mx + b

y = 9x + b

Plugin x = 0 and y = 5

5 = 0 + b

b = 5

y = 9x + 5

Five minutes after birth, a newborn is pale; has irregular, slow respirations; has a heart rate of 120 beats/min; displays minim
Natalija [7]

Answer:

5

Step-by-step explanation:

The Apgar score is calculated based on 5 medical criteria:  

-Appearance – skin color

-Pulse – heart rate (taken with a stethoscope or by feeling the umbilical cord)

-Grimace – reflex response

-Activity – muscle tone

-Respiration – breathing quality

Each one of the criteria is evaluated on a 0 to 2 scale, once every criteria are measured, the values are added up and the child would have an Apgar score between 0 and 10.  

Here:

Apparence = 0

Pulse = 2

Grimace = 1

Activity = 1

Respiration = 1

Total= 2 + 1 + 1 + 1 = 5

To test the impact performance of a 10 cm thick gymnastics mat, a 20 kg cylindrical
denis23 [38]

Answer:

A)196J

B)-208J

C)3467J

Step-by-step explanation:

We are given that a 20 kg cylindrical  mass is dropped onto the mat from a height of 1 m above the mat. During the impact,  the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to  only 4 cm thick.

So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m

a)

Using Conservations of energy

Potential energy at the top = Kinetic energy at the point before touching the surface

Kinetic energy = mgh= 20 \times 9.8 \times 1 = 196 J

b)

Work done  by the mat do to stop the fall of the cylinder =-mg(h+0.06)=-20 \times 9.8(1+0.06)=-208 J

C)

Work done=\text{Average force} \times \text{ Compression of mat}

208=F \times 0.06

F=3467J
