Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6 3/4 inches, and Frame B has a length of 7 1/2 inches. What is the width of frame a and frame b.
Answer:
Frame A width = 6.67 inches
Frame B width = 6 inches
Step-by-step explanation:
WA = width of frame A
WB = width of frame B
(WA)(6.75) = 45
WA = 6.67
(WB)(7.5) = 45
WB = 6
find the equation of the line m= -4 and contains the point (3,6)
Answer: y=-4x+6
Step-by-step explanation:
M is the slope in slope intercept form.
y=mx+b
And b is the Y intercept because when you plug in zero for x you get y=b.
So we know
y=-4x+b
Because m is the slope
And y is 6 because it is shown in the parentheses
So we know the answer is y=-4x+6

Answer:
B) 60.21 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches
8’6”=102’
14’2”=170’
Now find the area
1/2 x 102 x 170 = 8670 in²
This is one of the answers, but the quetion asks how many quart feet you need.
So, convert it back to feet.
8670 x 0.06944444444 = 60.2083333
(You could also have converted the two lengths to feet. 8’6” = 8.5 ft. 14’2” = 14.16666666. This way would probably have been faster.
1/2 x 8.5 x 14.166666 = 60.20833333)

For which equation is b = 5 not the solution?
options:
1. 8 - b = 13
2. b + 6 = 11
3. b + 4 = 9
4. 12 - b = 7
Answer:
option 2 and 3
b+6=11
b+4=9
Answer:
1. 8 - b = 13
Step-by-step explanation:
It says for which equation is b = 5 not the solution.
So, we need to plug in 5 into every b, and find out which one is incorrect.
1. 8 - 5 = 13 (incorrect)
2. 5 + 6 (correct)
3. 5 + 4 = 9 (correct)
4. 12 - 5 = 7 (correct)
Therefore, option 1 is the answer to your question.
which equation represents the linear function that is shown on the graph
Answer:
Y = (1/2)x - 2
Step-by-step explanation:
To compose a linear equation, always use the form
Y = Mx + C where C is the y-intercept and M is the gradient.
In this case, pick any 2 points on the graph to solve for M
e.g (8,2) and (6,1)
Gradient = (2 - 1) /(8 -6) given by (y1 - y2) / (x1 - x2) = 1 / 2
Substitute into the form, we get
Y = (1/2)x + C
Now, we use any point again on the graph,
e.g (6,1) and substitute as (x, y) into the above function.
We will get 1 = (6)(0.5) + C
C = -2
Piece them up and u get the full function.

Answer:
The area of the grass covered by the sprinkler water is approximately 78.54 feet^2
Answer:
78.54 feet
Step-by-step explanation:
10 is the diameter so 5 is the radius,

Which expressions are equivalent?
1. 3x-7y and -7y+3x
2. 3x-7y and 7y-3x
3. 3x-7y and 3y-7x
4. 3x-7y and-3y+7x
Answer:
1. 3x-7y and -7y+3x
Step-by-step explanation:
1. 3x -7y and -7y +3x
This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.
2. 3x -7y and 7y -3x
This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.
3. 3x -7y and 3y -7x
This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.
4. 3x-7 and -3y+7x
This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.

According to Newton's Second Law, if force equals 17 N and acceleration equals 8 m/s2, what is the mass in kilograms?
Answer as a number, rounded to the nearest thousandth?
Answer:
2.13kg
Step-by-step explanation:
fnet=ma
17=m(8)
17÷8 =m
2.13=m
Answer:
The mass is 2¹/₈, or 2.125, kg
Step-by-step explanation:
We know that force is equal to mass times acceleration, so given a force of 17 newtons and an acceleration of 8m/s², we can say:
[tex]f = ma\\m = f/a\\m = \frac{17\ N}{8\ m/s^2}\\m = \frac{17\ kg\times m/s^2}{8\ m/s^2}\\m = 17/8\ kg\\m = 2.125 kg[/tex]
giving us a mass of 2¹/₈, or 2.125 kg.
Mandy's dog will be having four puppies. Mandy performs
a simulation by tossing a coin to model whether these
puppies will be male or female.
• Let heads (H) = female puppy
• Let tails (T) = male puppy
The results of the simulation are:
1. THTT
6. HHHH
2. TTTH
7.HTHT
3. TTHH 8. HHHT
4. HTTT
9. THTH
5. TTTT
10. HHHH
What is the estimated probability that at least two of the puppies will be
female?
A. ) = 70%
B. 6 = 60%
30%
D.
50%
Answer: C 30 it was correct on my test
The estimated probability that at least two of the puppies will be female is 60%.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Let heads (H) be the female puppy
Let tails (T) be the male puppy.
The simulation results are the sample spaces.
[tex](THTT, TTTH, TTHH, HTTT, TTTT, HHHH, HTHT, HHHT, THTH, THTH)[/tex]
⇒ [tex]n(s)=10[/tex]
The event is the probability that at least two of the puppies will be
female.
[tex]e=(TTHH, HHHH, HTHT, HHHT, THTH, THTH )\\[/tex]
⇒ [tex]n(e)=6[/tex]
The estimated probability that at least two of the puppies will be
female, [tex]P(e)=\frac{n(e)}{n(s)}[/tex]
⇒ [tex]P(e)=\frac{6}{10}[/tex]
⇒ [tex]P(e)=0.6[/tex]
Thus the percentage of the female puppies = [tex](0.6)(100)[/tex]
⇒ [tex]60\%[/tex]
Hence we can conclude that the estimated probability that at least two of the puppies will be female is 60%.

A large factory that builds machines has three shifts, one that starts at 4:00 A.M., one that starts at noon, and one that starts at 8:00 P.M. The manager of the factory wanted to know whether there is an association between an employee’s work experience (less than five years with the company, between five and twenty years with the company, over twenty years with the company) and the time of the employee’s shift. The manager selected a random sample of 125 employees and classified employees by their shift time and work experience. What is an appropriate pair of hypotheses for the manager to use?
Answer:
if the worker has more experience, then they will have longer shifts because they will be better at their job and be able to complete more tasks.
Step-by-step explanation:
use and "if then because" structure in a hypothesis, and use common logic based on the info provided :)
Answer:
[tex]H_{0}[/tex] : Work experience is independent of the time of an employee's shift
[tex]H_{A}[/tex] : Work experience is dependent on the time of an employee's shift
Step-by-step explanation:
Since we have one population but multiple variables, so we are using a chi-square test of independence. Thus, our null should be that there is no association, and the alternative that there IS an association.
please help me with these problems.... please answer all the questions with the method I already started with... due at 11:59pm TODAY
Step-by-step explanation:
Howdy, did you do a, b, and c by yourself? Because there are some slight issues, so I'll do my best to explain.
a. 3x+5x
We know that x=2, so we can substitute 2 in for x right now, or we can combine like terms.
3x and 5x both have the variable x so we can add them easily to get 8x. If you substitute in 2, you're just multiplying 8×2, which is 16.
b. 5z+4z+z
Again, since
we know that z=-3, we can substitute in now, or we can combine like terms first. 5z, 4z, and z all have the variable x, we addition is easy. 5+4+1=10, so you'll have 10z. Substitute in -3 for z, and you're just multiplying 10×-3=-30
c. 3x+6+5x
This is trickier since 6 doesn't have the variable x. So to combine like terms means to only add 3x and 5x. So the equation will turn out looming like 8x+6. now substitute in 2 for x and you get
8(2)+6
16+6
22
d. 8y+8-4y
Combine like terms
4y+8
substitute in 5 for y
4(5)+8
20+8
28
e. 5z-4z+z
combine like terms
z+z
2z
substitute -3 for z
2(-3)
-6
f. 3x+6+5x-2
combine like terms
(so that's 3x+5x and 6-2)
8x+4
substitute in 2 for x
8(2)+4
16+4
20
g. 8y+8-4y-3
combine like terms
8y-4y+8-3
4y+5
substitute in 5 for y
4(5)+5
20+5
25
h. 5z-4z+z-3z
combine like terms
-z
substitute in -3 for z
-(-3)
double negatives make a positive
