Answer:The equation is 35+3m=45+2m and the answer is 10 minutes.
Step-by-step explanation:
35+3m=45+2m
Subtract 35 from both sides
Then you end up with 3m=10+2m
Then you subtract 2m from both sides
Then you end up with 1m=10
Then you divide both sides by 1 and your answer will be m=10

Use the equation below to find T, if W=62, m=4, and a=6
Answer:
T = 38
Step-by-step explanation:
T = 38 because:
1) Plug in all the variables into the equation
Equation: T = 62 - 4(6)
2) Next, solve the equation. First, do multiplication because of order of operations.
Equation: T = 62 - 24
3) Now just subtract 62 and 24
Equation: 38 = 62 - 24
Therefore, T = 38

66%
15%
5.51%
Answer:
66%
Step-by-step explanation:
Use conditional probability.
P(full | holiday) = P(full AND holiday) / P(holiday)
P(full | holiday) = 0.19 / 0.29
P(full | holiday) ≈ 0.66

a scale factor of 1 will produce a congruent image
Answer:
no factor of one
Step-by-step explanation:
If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent. The word "dilate" is often heard in relation to the human eye.

how much kinetic energy does a 4 kg cats have while at 9 m/s
Answer:
162 Joules
Step-by-step explanation:
Remember, the equation for the kinetic energy of an object is:
[tex]K=\frac{1}{2}mv^{2}[/tex]
where m is the mass of the object in kg (kilograms), v is the velocity of the object in m/s (meters per second), and K is the kinetic energy of the object in J (joules).
We are given that the cat's mass is 4 kg. We will use this for m. We are also given that the cat is moving at 9 m/s. This would be it's speed. We can use this for velocity, or v. Plugging in we get:
[tex]K=\frac{1}{2}mv^{2}=\frac{1}{2}(4)(9)^{2}=(2)(81)=162[/tex]
So K, or the kinetic energy, would be 162J.

Find the mean, u, for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth. n=676; p=0.7
Answer:
[tex]\mu=473.2[/tex]
Step-by-step explanation:
Binomial Distribution
The binomial distribution is commonly used to model the number of successes in a sample of size n drawn with replacement from a population of size N.
The mean value of a binomial distribution is given by:
[tex]\mu=np[/tex]
Where b is the number of trials and p is the success probability for each trial.
We need to find the mean value with parameters n=676 and p=0.7, thus:
[tex]\mu=676\cdot 0.7[/tex]
[tex]\boxed{\mu=473.2}[/tex]

Hanna puts $4,383 in a savings account with an annual interest rate of 5.2 percent for 3 years. Into which variable should she substitute 4,383 in the simple interest formula I = p r t?
I
p
r
t
Answer:
the CORRECT answer is p
Step-by-step explanation:
The simple interest is $683.748. Therefore, Hanna should submit 4,383 into variable p in simple interest formula.
Given that, principal (P)=$4,383, R=5.2% and T=3 years.
What is simple interest formula?The formula to find the simple interest is S.I=P×T×R/100.
Where, P= Principal, R= Rate of interest and T= Time period.
Now, S.I=4,383×3×5.2/100
=$683.748
The simple interest is $683.748. Therefore, Hanna should submit 4,383 into variable p in simple interest formula.

Which of the following parent functions has a domain and range of all real
numbers?
A. Cubic
B. Reciprocal
C. Quadratic
D. Absolute value
Parent functions has a domain and range of all real numbers is a Cubic function
Given :
We need to find the parent function that has a domain and range of all real
numbers.
Domain is the set of all x values and range is the set of y values.
For any cubic function there is no restriction for x
For each value of x there is a y value
So, domain and range of cubic function is set of all real numbers
For reciprocal function , there will be x in the denominator . So there will be some restriction for x.
For any quadratic function , domain is set of all real numbers. For quadratic we get U shaped graph . It means there is some restriction for y.
So range cannot be real numbers
For absolute value function , we get V shaped graph . so there is some restriction for y. Range cannot be all real numbers.

Find an equation of the circle and sketch it if it has: Tangent to x-axis, r=4, contains (–5,8)
B
Find an equation of the circle and sketch it if it has:
Diameter endpoints (2, 5) and (0, 3)
C
Find an equation of the circle and sketch it if it has:
Center on x=3, tangent y-axis at (0, 5)
Answer:
A. [tex](x+5)^2+(y-4)^2=16[/tex]
B. [tex](x-1)^2+(y-4)^2=2\\[/tex]
C. [tex]$\left(x-3\right)^2+\left(y-5\right)^2=9$[/tex]
Step-by-Step Explanation:
A. Tangent to x-axis, r=4, contains (-5,8)
The equation of a circle is this: [tex](x-h)^2+(y-k)^2=r^2\\[/tex]
Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=4^2=16[/tex]
Because the circle is tangent to the x-axis, the point (-5,8) will be the top of the circle.
Therefore, the center is (-5,4), where -5=h and 4=k.
The answer is [tex](x+5)^2+(y-4)^2=16[/tex]
B. Diameter endpoints (2,5) and (0,3)
To solve for the diameter, we can use this equation: [tex]d=\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2 }[/tex]
[tex]d=\sqrt{(2-0)^2+(5-3)^2 }\\\\d=\sqrt{2^2+2^2}=\sqrt{4+4} =\sqrt{8}= 2\sqrt{2}[/tex]
Because the radius is half of the diameter, [tex]r=\sqrt{2}[/tex]
Therefore, we know that our equation will be: [tex](x-h)^2+(y-k)^2=(\sqrt{2}) ^2=2[/tex]
Then, we can decipher that h=1, as the midpoint of 0 and 2 is 1, and k=4, as the midpoint of 3 and 5 is 4.
The answer is [tex](x-1)^2+(y-4)^2=2[/tex]
C. Center on x=3, tangent to y-axis at (0,5)
We can see that the center is (3,5). Therefore, the equation is [tex](x-3)^2+(y-5)^2=r^2\\[/tex]
To solve for r, we can substitute the point (0,5) into the equation.
[tex](0-3)^2+(5-5)^2=r^2\\(-3)^2+(0)^2=r^2\\r^2=9[/tex]
The answer is [tex](x-3)^2+(y-5)^2=9[/tex]
