Answer: 41
Step-by-step explanation:
The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

Step-by-step explanation:
what is 13q - 9q + 5 = 17
the answer is: q=3
start by combining like terms (13q - 9q) which would leave you with 4q + 5 = 17. subtract 5 from both sides and you're left with 4q = 12. divide by 4 on both side and you get q = 3
Answer:
q=3
Step-by-step explanation:
13q - 9q + 5 = 17
13q - 9q = 17 - 5
4q = 12
4q/4 = 12/4
q = 3
The correlation coefficient for the costs and sizes of storage container is 0.55. How
are the costs and sizes of the containers related?
Answer:
There is a positive correlation between both variables.
Step-by-step explanation: That is to say, the relation between the cost and the size of the storage containers is growing.
As the size of the container increases the cost also increases.
The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium positive correlation
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
The costs and sizes of the containers are moderately correlated.
What is a correlation coefficient?A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
We have,
The correlation coefficient for the costs and sizes of the storage container is 0.55.
We know that,
Correlation coefficients whose magnitude is between 0.5 and 0.7 indicate that the variables are moderately correlated.
Correlation coefficients whose magnitude is between 0.3 and 0.5 indicate that the variables are a low correlation.
Since the correlation coefficient for the costs and sizes of the storage container is 0.55, it is between 0.5 and 0.7.
So it is moderately correlated.
Thus the costs and sizes of the containers are moderately correlated.

3. The ratio of milk water in 55 liters of Adultered milk is 7:4. How much water must be added to make the mixture Ratio of 7:6? a)5 liters b)10 liters c)15 liters
Answer:
The answer is B 10 L
Step-by-step explanation:
let milk and water in the mixture be 7x and 4x equal 55L
[tex]7x + 4x = 55 \\ 11x = 55 \\ x = 5[/tex]
[tex]7(5) = 35l \: milk \\ 4(5) = 20l \: water[/tex]
let x Liters of water he added so that the ratio is 7:6
[tex] \frac{35l \: milk}{20l \: water + x} = \frac{7}{6} [/tex]
cross multiply
[tex]35l \: milk \times 6 = (20l \: water + x)7 \\ 210l \: m= 140l \: w + 7x \\ 210l \: m - 140l \: w = 7x \\ 70l = 7x \\ \frac{70}{7} = \frac{7x}{7 } \\ x = 10 l \: water[/tex]

To find the y-value that matches with the x-value, we will need to plug in the x-value and simplify the expression.
f(-2) = sqrt(-2 + 2) - 6
f(-2) = sqrt(0) - 6
f(-2) = -6
f(-1) = sqrt( -1 + 2) - 6
f(-1) = sqrt(1) - 6
f(-1) = 1 - 6
f(-1) = -5
f(2) = sqrt(2 + 2) - 6
f(2) = sqrt(4) - 6
f(2) = 2 - 6
f(2) = -4
f(7) = sqrt(7 + 2) - 6
f(7) = sqrt(9) - 6
f(7) = 3 - 6
f(7) = -3

Answer:
There is no direct question on here so I'll just assume you're asking how many rides she can get on???
Step-by-step explanation:
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = 30
6 x 6 = 36
6 x 7 = 42
So she can get on about 6 rides (once again, if thats what ur trying to ask..)

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km
How to find Length of Similar Triangles?We are given a Triangle PQR.
In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.
In Triangle SRT, Side RT = 33 kilometers.
Using concept of ratio of similar triangles, we can say that;
ST/RT = PQ/PR
Thus;
ST = RT * (PQ/PR)
ST = 33 * (16/24)
ST = 22 Km

find the slope of the parabola y equals to e^(-4x) sin6x at the point P(2,4). write an equation for the tangent to the parabola at this point
The equation of the tangent line to the curve is:
[tex]y - 4 = 0.0024(x - 2)[/tex]
Which has a slope of 0.0024.
The tangent line of a curve [tex]f(x)[/tex] at a point [tex](x_0,y_0)[/tex] is given by:
[tex]y - y_0 = f^{\prime}(x_0)(x - x_0)[/tex]
In this problem, the curve is:
[tex]f(x) = e^{-4x}\sin{6x}[/tex]
The derivative is:
[tex]f^{\prime}(x) = -4e^{-4x}\sin{6x} + 6e^{-4x}\cos{6x}[/tex]
Point P(2,4), thus [tex]x_0 = 2, y_0 = 4[/tex].
The slope is:
[tex]f^{\prime}(2) = -4e^{-4(2)}\sin{6(2)} + 6e^{-4(2)}\cos{6(2)} = 0.0024[/tex]
Then, the equation of the line is:

[tex]y - 4 = 0.0024(x - 2)[/tex]

Answer:
A scuba diver was exploring a reef 32.12 m below sea level. The diver ascended to the surface at a rate of 8.8 m/min.
a. using the formula d = rt, so 32.12 m = 8.8m/min (t)
b. it is reasonable to write the distance as positive because the diver is accending/ going up the surface

Answer please! branliest
Answer: 8p + -4p = 2p + 6
Combine like terms: 8p + -4p = 4p
4p = 2p + 6
Reorder the terms:
4p = 6 + 2p
Solving
4p = 6 + 2p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
4p + -2p = 6 + 2p + -2p
Combine like terms: 4p + -2p = 2p
2p = 6 + 2p + -2p
Combine like terms: 2p + -2p = 0
2p = 6 + 0
2p = 6
Divide each side by '2'.
p = 3
Simplifying
p = 3
