Answer:
the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
Step-by-step explanation:
This talks about equalities in math,
We are told about Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour, this can be interpreted as
250 - 30h
Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour, this can be interpreted as
400 - 50h
We were now asked how many hours the altitude of mountain climber b be lower than the altitude of mountain climber A, we can interpret this as
(400 - 50h) < (250 - 30h )
We can collect the like terms here
-50h + 30h < 250 - 400
-20h < - 150
The negatives sign can cancelled out, we have
Note that multiplying or dividing by a negative THE INEQUALITY SIGN MUST BE FLIPPED
20h > 150
h > 150/20
h > 7.5
Therefore, the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
Cows and horses cost $250 each and sheep and goats each cost $200 at the county fair. Chickens sell for $50. How much could McDonald make by selling all his animals except the dogs and cats?
Answer:
the total amount of animals in McDonald's farm is missing, so I looked for a similar question and found the attached image:
McDonald can earn:
15 cows x $250 = $3,750
2 horses x $250 = $500
20 sheep x $200 = $4,000
25 goats x $200 = $5,000
17 chickens x $50 = $850
total = $14,100

What is the slope of the line that goes through points (−3,−4) and (−7,16)? please help
Answer:
5
Step-by-step explanation:
slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
[tex]\frac{20}{-4}[/tex]
You can reduce this to [tex]-\frac{5}{1}[/tex], or 5.
The slope of the line will be "-5".
Given points are:
[tex](x_1,y_1) = (-3,-4)[/tex][tex](x_2,y_2) = (-7,16)[/tex]As we know the formula,
→ Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
[tex]= \frac{16-(-4)}{-7-(-3)}[/tex]
[tex]= \frac{16+4}{-7+3}[/tex]
[tex]= -\frac{20}{4}[/tex]
[tex]= -5[/tex]

need help with these 3
Answer:
1.) x = 110
[tex]\frac{3}{22} =\frac{15}{x}[/tex]
So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110
[tex]\frac{3 * 5}{22*5} =\frac{15}{110}[/tex]
2.) x = 72
[tex]\frac{x}{16} =\frac{9}{2}[/tex]
For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72
[tex]\frac{72}{16} =\frac{9}{2}[/tex]
3.) c = 24
[tex]\frac{3}{5} =\frac{c}{40}[/tex]
For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24
[tex]\frac{3*8}{5*8} =\frac{24}{40}[/tex]

Darius took a road trip to their grandmother's house. They drove at a constant speed of 60 miles per hour for 2 hours. They took a break and then finished the rest of their trip driving at a constant speed of 50 miles per hour for 2 hours. What was the total distance, in miles, of Darius' trip?
Answer: 220 miles
Step-by-step explanation:
Distance travelled is calculated as:
= Speed × Time
Based on the scenario on the question, the total distance, in miles, of Darius' trip will be:

Find the value of X
Answer:
x = 114°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
The value of angle x in the triangle will be equal to 114°.
What is an exterior angle?When one side of a triangle is extended, an external angle of the triangle is created. The external angle of the triangle is the non-straight angle (the one that is not simply the extension of the side) that is outside the triangle but close to an interior angle.
Given that a side of the triangle below has been extended to form an exterior angle of 132°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
Therefore, the value of angle x in the triangle will be equal to 114°.

The total cost, c, in dollars to create calendars for a fundraiser can be found using the function c=5.5u+25 where u is the number of calendars made. If there are at least 10 calendars made, what is a possible domain for this function?
A: 10≤x≤100
B: {-12, -11, 12, 20, 50}
C: {10, 11, 12, 13, 14}
D: 0≤x<50
Answer:
The correct option is;
{10, 11, 12, 13. or 14}
Step-by-step explanation:
The given function for the total cost, c, to create calendars is c = 5.5u + 25
The domain of a function are the values of the input variables of the function with which the output (the values) of the function are found
Therefore, the domain of the given function are the values of the variable, u, in the function
Where;
u = The number of calendars made
∴ When u ≥ 10, we have;
The possible domain for the function are u = 10, 11, 12, 13. or 14...
Therefore, the correct option is {10, 11, 12, 13. or 14}
Find the zero of the function.
g(x) = x2 + 22x + 121

Answer:
x = -11
Step-by-step explanation:
To find the zero of this function, factor the equation:
g(x) = [tex]x^{2} +22x+121[/tex]
g(x) = (x + 11) (x + 11)
g(x) = [tex](x+11)^{2}[/tex]
The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.

A daredevil decides he wants to jump out of a plane and parachute to the U.S.S. Showboat. He knows he needs to leave the plane at an angle of 58˚ from vertical and he knows he wants to wait until the horizontal distance to the boat is 1000yd. How far away should the plane be from the boat to complete his aerial stunt successfully?
Answer:
1179 yards
Step-by-step explanation:
The question can be described by a right angled triangle.
The angle of depression of the boat from the plane = [tex]90^{o}[/tex] - 58˚
= [tex]32^{o}[/tex]
Let the distance from the plane to the boat be represented by x.
Thus, applying the appropriate trigonometric function, we have;
Cos θ = [tex]\frac{Adjacent}{Hypotenuse}[/tex]
Cos [tex]32^{o}[/tex] = [tex]\frac{1000}{x}[/tex]
x = [tex]\frac{1000}{Cos 32^{o} }[/tex]
= [tex]\frac{1000}{0.8481}[/tex]
= 1179.11
x = 1179 yds
The plane should be 1179 yards away from the boat.
: Suppose that you plan to take a trip to your dream destination. You
would like to know the shortest distance between your starting point and your
destination. When calculating distances on a plane, you need only consider two
dimensions because you are on a flat surface. However, when finding distances
between two points on Earth, you must take into the account the curvature of a
sphere. In this portfolio, you will extend your knowledge of two-dimensional vectors
to three-dimensional vectors in order to find the shortest distance between two
points on the surface of Earth.

The equation in the standard form is
[tex]y+2x=5[/tex]
Step-by-step explanation:
Given the points
(6, -7)(4, -3)Finding the slope between (6, -7) and (4, -3)
[tex]\left(x_1,\:y_1\right)=\left(6,\:-7\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-3-\left(-7\right)}{4-6}[/tex]
[tex]m=-2[/tex]
As the point-slope form is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -2 and the point (6, -7)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
converting the equation in standard form
[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]
[tex]y+7=-2\left(x-6\right)[/tex]
subtract 7 from both sides
[tex]y+7-7=-2\left(x-6\right)-7[/tex]
[tex]y=-2x+5[/tex]
[tex]y+2x=5[/tex]
Therefore, the equation in the standard form is
[tex]y+2x=5[/tex]
