A substance requires 310 J of heat to raise the temperature from 19
°C to 42 °C.. If the mass of the substance is 20 g, what is the specific
heat of the substance?
Answer:
.674 j / (g-C)
Step-by-step explanation:
Spec heat = heat required to raise 1 gram of substance 1 degree celsius
Spec heat units : j / (gm-C)
soooo 310 j / (20g * (42-19)C = .674

Step-by-step explanation:
Multiply each x value by 1/3 then add 2. Since the numerator is 1, you would multipy by one and divide by the denominator of 3, so you really need to divide each x value by 3 then add 2.
-6:
-6/3 = -2
-2 + 2 = 0
-3:
-3/3 = -1
-1 + 2 = 1
0:
0/3 = 0
0 + 2 = 2
3:
3/3 = 1
1 +2 = 3
6:
6/3 = 2
2 + 2 =4

25(q-954)=775 what is q?
Answer:
The value of q = 985
Step-by-step explanation:
==> 25(q-954)=775
=> q-954 = 775/25
=> q-954 = 31
=> q = 31+ 954
=> q = 985
Answer:
q = 985
Step-by-step explanation:
25 (q-954) = 775
q-954 = 775/25
q = 31 + 954
q = 985

A high school basketball coach was searching through records and found that the average height of high school basketball players is 73 inches with a standard deviation of 2.1 inches. The distribution of heights is an approximately normal distribution.
a. The typical basketball team usually has around 16 players. Describe the sampling distribution for samples of size n = 16.
b. Is it surprising to find a random sample of size n = 4 to have an average height over 75 inches? Give appropriate statistical evidence
c. Suppose the population described in the problem was clearly NOT normal. Could the question in part (b) still be answered? Explain why it could still be answered. If not, explain why.
Answer:
The heights of basketball players have an approximate normal distribution with mean, μ = 79 inches and a standard deviation, σ = 3.89 inches.

find the solution of y=x+3 and y=2x+6
Answer:
x = 3 and y = 0
Step-by-step explanation:
To find the solution where you have two equations is called a System of Equations.
What you do is you notice there are two equations and the let both equations equal each other. We can do this because both equations start with a y. These "y" work like puzzles and you can connect the "x+3" and "2x + 6" together. Then solve for it. Here's what i mean,
y = x+3
y = 2x+6
Now connecting them,
x+3 = 2x+6
Subtract x from both sides
3 = x + 6
Subtract 6 from both sides,
x = -3
Now solve for y,
y = -3 + 3 = 0
So our solution is x = 3 and y = 0.
Answer:
(x, y) = (-3, 0)
Step-by-step explanation:
Substitution or elimination work well for solving this system of equations.
__
EliminationSubtract the first equation from the second.
(y) -(y) = (2x +6) -(x +3)
0 = x +3
-3 = x . . . . . . . subtract 3
y = (-3) +3 = 0 . . . . use the first equation to find y
(x, y) = (-3, 0)
__
SubstitutionUse the second equation to substitute for y in the first.
2x +6 = x +3
x = -3 . . . . . . . . . subtract x+6 from both sides
y = (-3) +3 = 0 . . . . find y using the first equation
(x, y) = (-3, 0)

Answer:
4 times, 2/15, 4/30
Step-by-step explanation:
The predicted probability is 15/30.
So, 19/30-15/30 IS 4/30, or 2/15.

Answer:
2(3-√13) is the answer
Step-by-step explanation:
Given that,
x = \frac{3 - \sqrt{13} }{2}
or, \frac{1}{x} = \frac{2}{3 - \sqrt{13} } (Taking reciprocal on both sides)
We know that,
(a + b)² = a² + b² + 2ab
or, (x \ + \frac{1} {x})^{2} = {x}^{2} + \frac{1}{x {}^{2} } + 2
or, {x}^{2} + \frac{1}{x {}^{2} } = (x \ + \frac{1}{x })^{2} - 2
Now,
or, {x}+ \frac{1}{x } = \frac{3 - \sqrt{13} }{2} + \frac{2}{3 - \sqrt{13} }
or, (3 - \sqrt{13 {})^{2} } + 4
2(3-√13) is the answer

Which of the following is a situation in which an equation CANNOT be solved using the quadratic formula ?
Answer:
C. One term has degree 3
Step-by-step explanation:
The quadratic formula is used to find the zeros of degree 2 polynomials. The coefficient of the linear term does not matter, and the coefficient of the x² term may be anything except 0.
If the degree of the polynomial is 3, the quadratic formula does not apply.
this is for my geometry final please help me pass
Step-by-step explanation:
cos(x) = 5/13
the relation is
sin²(x) + cos²(x) = 1
so,
sin²(x) + (5/13)² = 1
sin²(x) + 25/169 = 169/169
sin²(x) = 144/169
sin(x) = 12/13

The length of a rectangle is 4/5 of the width. The length of the rectangle is 3/5 meter. Which equation can be used to find w, the width of the rectangle in meters?
A 3/5w = 4/5
B 4/5w = 3/5
C 3/5 + w = 4/5
D 4/5 + w = 3/5
Answer:
B: 4/5w = 3/5
Step-by-step explanation:
The length of the rectangle is stated as being 4/5 of the w. (4/5 * w)
The length is also stated specifically as being 3/5m so that will equal 4/5w on the other side of the equation.
Bonus:
You could work out the equation as
4/5w = 3/5m
multiply by 5
4w = 3m
divide by 4
w = 0.75m (or 3/4m)
33 markers cost $5.79
Which equation would help determine the cost of 13 markers
Answer:
3/$5.79 = 13/x
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x. Divide $5.79 by three to get the cost of one marker, $1.93. Then multiply the cost of one marker by 13 on the left. This will get the total value which is $25.09.
Which probability describes an event that is “very likely”?
A. 0.125
B. 0.9
C. 1
D. 0.50
The probability that describes an event as "very likely" is option B, 0.9.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain.
A probability of 0.9 means that there is a 90% chance that the event will occur, which is a high likelihood of the event happening. In general, probabilities between 0.7 and 1 are often considered to be "likely" or "very likely".
Therefore, the correct option is B.
