Answer: 7 (x+4)
Step-by-step explanation: Since the expression asks for 7 times the sum of a number and 4, you would put x + 4 in parentheses since multiplying 7 comes afterwards.
Let m AngleA = 40°. If AngleB is a complement of AngleA, and AngleC is a supplement of AngleB, find these measures
Answer:
mAngleB = 50 degrees
mAngleC = 130 degree
Step-by-step explanation:
The way I did this was by subtracting the given "mAngleA = 40" from the angle that complementary angles are at: 90 degrees, which means that equals 50 degrees. Then, I did the same with mAngleC with the angle that supplementary angles are at: 180 degrees. 180 - 50 = 130 degrees.

Passes through the origin and has a slope of 2/3
Answer:
y = [tex]\frac{2}{3}[/tex] x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( where m is the slope )
Here m = [tex]\frac{2}{3}[/tex] , thus
y = [tex]\frac{2}{3}[/tex] x ← equation of line

A peach farmer has two different varieties (named Variety A and Variety B) of peach trees on her land. Thirty percent of her trees are Variety A peaches and the other 70% are Variety B peaches. The weights of Variety A peaches are normally distributed with a mean of 90 grams and a standard deviation of 8 grams. The weights of Variety B peaches are normally distributed with a mean of 107 grams and a standard deviation of 12 grams. a. What proportion of Variety A peaches weigh between 100 and 110 grams
Answer:
12.03%
Step-by-step explanation:
The z score i used to measure by how many standard deviations the raw score is above or below the mean. It is given by the equation:
[tex]z=\frac{x-\mu}{\sigma}\\ \\where\ \mu=mean,\sigma=standard \ deviation,x=raw\ score[/tex]
a) For variety A, the mean = μ = 90, standard deviation = σ = 8
For x = 100 grams:
[tex]z=\frac{x-\mu}{\sigma} =\frac{100-90}{9} =1.11[/tex]
For x = 110 grams:
[tex]z=\frac{x-\mu}{\sigma} =\frac{110-90}{9} =2.22[/tex]
From the normal distribution table, P(100 < X < 110) = P(1.11 < z < 2.22) = P(z < 2.22) - P(z < 1.11) = 0.9868 - 0.8665 = 0.1203 = 12.03%

Hello.
To convert a fraction to a percentage, divide the two numbers, then multiply the result by 100.
49/46 = 1.06 (rounded)
1.06 * 100 = 106
Therefore, 49/46 as a percent is 106%.

Write the equation of the line MN, which is formed by the
points M-3, 5) and N(2, 0).
Step 1: Identify the slope. m =
Answer:
-1
Step-by-step explanation:
Took the assignment! :)
The equation of the line MN is y = -x + 2.
The slope is -1.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
To find the slope of the line MN, we can use the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where[tex](x_1, y_1) = (-3, 5)[/tex] is the coordinate of point M, and [tex](x_2, y_2) = (2, 0)[/tex] is the coordinate of point N.
Now,
m = (0 - 5) / (2 - (-3))
m = -5 / 5
m = -1
So the slope of the line MN is -1.
Now that we know the slope, we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
where m = -1 is the slope we just found and [tex](x_1, y_1) = (-3, 5)[/tex] is one of the points on the line.
Plugging in the values, we get:
y - 5 = -1(x - (-3))
y - 5 = -x - 3
y = -x + 2
Therefore,
The equation of the line MN is y = -x + 2.

Randy wants to attach a 21 foot string of lights to the top of the 18 foot mast of his sailboat. How far from the base of the mast should he attach the end of the light string?
Answer:
10.81665
Step-by-step explanation:
In order to solve this we can use pythagorean theorem, or [tex]a^{2} + b^{2} = c^{2}[/tex]
C represents the hypotenuse and a and b represent the two other sides.
We have the hypotenuse, 21 feet. We also have a side, 18 feet. We can plug these in and solve for a.
[tex]a^{2} + 18^{2} = 21^{2}[/tex]
[tex]a^{2} + 324 = 441[/tex]
Subtract 324 from both sides.
[tex]a^{2} =117[/tex]
Square root both side to remove the square.
[tex]\sqrt{a^{2} } =\sqrt{117}[/tex]
[tex]a=10.81665[/tex]
Hope this helps!
This question is based on the Pythagorean theorem. Therefore, 10.81665 feet far from the base of the mast should he attach the end of the light string.
Given:
Randy wants to attach a 21 foot string of lights to the top of the 18 foot mast of his sailboat.
We need to determined the base of the mast should he attach the end of the light string.
According to the question,
By using Pythagorean theorem,
[tex]a^2 + b^2 = c^2[/tex]
Here, it is given that, b = 18 and c = 21.
Putting this value in above formula.
We get,
[tex]a^2 + 18^2 = 21^2[/tex]
[tex]a^2 = 441 - 324\\\\a^2 = 117[/tex]
Square root both sides. We get,
[tex]\sqrt{a^2} = \sqrt{117}[/tex]
a = 10.81665.
Therefore, 10.81665 feet far from the base of the mast should he attach the end of the light string.
