to the right22 N22/15 ≈ 1.467 m/s²5/147 ≈ 0.034Step-by-step explanation:
a) Friction opposes motion, so is in the opposite direction of the net force on the sled. Taking "left" to be "positive", the two animals are applying a net force of +42 N -15 N = 27 N. That is to the left, so the friction force is to the right.
__
b) The total of forces applied by the animals and friction is ...
27 N -5 N = 22 N . . . to the left
__
c) Acceleration can be found from the relation ...
a = F/m . . . . 'm' is mass
a = (22 N)/(15 kg) = 22/15 m/s² . . . . 'm' is meters
__
d) The coefficient of friction is the ratio of friction force to the normal force on the surface producing the friction. Here, that normal force is the force due to gravity acting on the 15 kg mass of the sled.
coefficient of friction = (5 N)/(9.8 m/s²·15 kg) = 5/147
coefficient of friction ≈ 0.034
Answer:
1. to the right
2. 22 N
3. 22/15 ≈ 1.467 m/s²
4. 5/147 ≈ 0.034

What is the slope and equation of a line perpendicular to the y-axis passing through point (–5, –3)?
Answer:
Slope: m = 0
Equation: y = -3
Step-by-step explanation:
A line perpendicular to the y-axis always has a slope of 0. Slope is calculated by (y2-y1)/(x2-x1) or rise/run or delta y/delta x (they're all the same thing, delta means difference and is notated with a triangle). When there is no change in y (perpendicular to the y-axis), no matter what the change in x is, the slope will be 0.
Since it is given that one of the points has a y-value of -3, the equation for this line would be y = -3. The formula for a linear equation is y=mx+b. Since the slope is 0, the value of mx is 0, and therefore not needed in the equation. b represents the y-intercept and in this case would be -3.
Solve for y

2.______-0.0369=0.1246
Answer:
1) 0.53
2) 0.1615
Step-by-step explanation:
1) ______ + 0.37 = 0.9
______ = 0.9 - 0.37 = 0.53
2)______ - 0.0369 = 0.1246
______ = 0.1246 + 0.0369 = 0.1615
Answer:
1. 0.53
2.0.1615
Step-by-step explanation:
1.______+0.14+0.23=0.9
let the blank space be x
here,
x+0.14+0.23=0.9
or, x + 0.37=0.9
or, x=0.9- 0.37
: . x= 0.53
2. ______-0.0369 =0.1246
let the blank space be x
here,
x-0.0369= 0.1246
or,x=0.1246+0.0369
: . x= 0.1615

Question 7
Which radical expression consists of two perfect squares?
A
V16
B
V25
С
125
D
V21
Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.

minutes do you set for the sterilizer?
A. 90
B. 120
C. 180
D. 240
E. 500
Answer:
B
Step-by-step explanation:
120/60=2
2 hours
The time required in minutes to set the sterilizer is 120. The correct option is B.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that you work in a hospital, instructions for an instrument state that it should be cleaned in the sterilizer for two hours.
The time in minutes will be calculated as:-
Time = 2 hours
Time = 2 x 60 minutes
Time = 120 minutes
Therefore, the time required in minutes to set the sterilizer is 120. The correct option is B.

Jamel has a cell phone that has unlimited minutes and texts for $45 a month, but he has to pay $5 for each gigabyte of data he uses. If he does not want to spend more than $65 for his cell phone each month, how many gigabytes can he use?
Answer:
I think it's 4 gigabytes
Step-by-step explanation:
He only wants to pay 65$ and he already spends 45$ on his phone already. So you only have 20 dollars until his grand totaly of 65$ so 5x4= 20 so he can only use 4 gigabytes. Does that make sense? Hope I helped eheh
