Step-by-step explanation:
5x-22+4x+4 = 90
9x-18=90
9x=108
x=12
4*12+4
52
Answer:
x=12 Hope this helps!!!
Step-by-step explanation:
Remember a straight line equals 180 and when you have the box the angle is 90 degrees. Try solving the equation 5x-22+4x+4+90=180.
5x-22+4x+4+90=180 (combine like terms)
9x+72=180 (subtract 72 from both sides)
9x=108 (divide 9 on both sides)
x=12

In the U.S. federal government debt totaled 5 trillion dollars. In 2008 the total debt reached 10 trillion dollars. Which of the following statements about the doubling time of the U.S. federal debt is true based on this information
a) the doubling time is getting bigger
b) the doubling time of the federal debt in 1995 was 13 years
c) the doubling time of the U.S. federal debt is alway 13 years
d) if the federal deficit continues to increase with the same doubling time as in 1995 the federal deficit will be 20 billion dollars in 2013
Answer:
A
I think the answer is A. The doubling time is getting bigger, because the debt is so rapidly increasing, and no one is paying off the USA's debt.
Penny is a 27-year-old competitive runner. She currently runs 50-60 miles per week. Most of her running is on flat ground and she competes in distance races at a pace of 6:30 per mile. For an upcoming race she would like to know what pace she should try to maintain on the long hill with an average grade of 8%. She has a measured VO2max of 65 mL/kg/min. Assuming she can run between 75 and 85% of her VO2max for extended periods of time, determine the approximate speeds and pace per mile should she anticipate for this hill at a) 75% and b) 85%. Report m/min, mph, and min/mile for each answer
a) _______m/min, _______mph, ______min/mile
b) _______m/min, _______mph, ______min/mile
Answer:
a) 8.67m/min, 6.9225 mph, 0.1155min/mile
b) 7.647m/min, 7.8455mph, 0.1309min/mile
Step-by-step explanation:
pennys pace = 6:30 min/mile
= 13/2 min per mile
1 mile/(13/2)
= 0.15385 mile/minute
approximately 0.154
1 mile/(13/2minutes) = 1mile(6.5x1/60)
= 9.231 mph
from above
a. 75% VOx max
= 13/2 * 100/75
= 8.67min/mile
mph = 9.23 * 0.75
= 6.9225mph
mile/min = 0.154 * 0.75
= 0.1155m/min
b. 85% VOx max
min/mile = 13/2 * 100/85
= 7.647min/mile
mph = 9.23 * 0.85 = 7.8455mph
mile/min = 0.154 * 0.85 = 0.1309m/min

Formalize the following argument by using the given predicates and then rewriting the argument as a numbered sequence of statements. Identify each statement as either a premise, or a conclusion that follows according to a rule of inference from previous statements. In that case, state the rule of inference and refer by number to the previous statements that the rule of inference used. Dogs bark at cats. Max is a dog. Moonbeam is a cat. Therefore, Max barks at Moonbeam. Predicates: B(x,y) = "x barks at y". D(x) = "x is a dog". C(x) ="x is a cat". The common domain of discourse is all animals.
Based on the inference, we can conclude that Max barks at Moonbeam.
What's the inference?To formalize the argument, we can use the given predicates and rewrite the statements as a numbered sequence, identifying each statement as either a premise or a conclusion that follows according to a rule of inference from previous statements. Here's the formalization:
Premise: Dogs bark at cats. (For all animals x and y, if D(x) and C(y), then B(x, y).)
Premise: Max is a dog. (D(Max))
Premise: Moonbeam is a cat. (C(Moonbeam))
Conclusion: Max barks at Moonbeam. (B(Max, Moonbeam))
In this formalization, statement 4 is the conclusion, and it follows from statements 1, 2, and 3. The rule of inference used is the universal instantiation, which allows us to instantiate the universal statement from statement 1 to a specific case involving Max (statement 2) and Moonbeam (statement 3). Therefore, we can conclude that Max barks at Moonbeam.

The first step in determining the solution to the system of equations, y = -x2 - 4x – 3 and y = 2x + 5, algebraical
set the two equations equal as –x2 - 4x - 3 = 2x + 5. What is the next step?
O Set y = 0 in y = -x2 - 4x - 3.
O Factor each side of the equation.
O Use substitution to create a one-variable equation.
O Combine like terms onto one side of the equation.
Answer:
Option (4)
Step-by-step explanation:
Given system of equations is,
y = -x²- 4x - 3
y = 2x + 5
To get the solution of the system of equations algebraically,
2x + 5 = -x²- 4x - 3
Now combine like terms onto one side of the equation.
-x² - (4x + 2x) - (3 + 5) = 0
x² + 6x + 8 = 0
Then factorize the equation,
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) =0
(x + 2) (x + 4) = 0
x = -2, 4
Option (4) is the answer.
Answer:
Combine like terms onto one side of the equation
Step-by-step explanation:
Given the first step in determining the solution to the system of equations,
y = –x2 – 4x – 3 and y = 2x + 5, algebraically as setting the two equations equal as shown: –x2 – 4x – 3 = 2x + 5, the next step will be to combine like terms onto one side of the equation. The like terms are the terms containing the variable x as shown;
-x²-4x-2x = 5+3
As we can see, the term containing x in the right-hand side of the equation (i.e 2x) is being brought to the left side of the equation. This will be the next step in the calculation

A rowing team rowing with the current traveled 36 km in 3 h. Rowing against the current, the team rowed 12 km in the same amount of time. Find the rate of the rowing team in calm water and the rate of the current.
Answer:
team: 8 kphcurrent: 4 kphStep-by-step explanation:
The downstream speed is ...
speed = distance / time
speed = 36 km/(3 h) = 12 km/h
The upstream speed is ...
12 km/(3 h) = 4 km/h
__
If b and c represent the speeds of the boat and current, respectively, then we have ...
b + c = 12
b - c = 4
Adding these gives ...
2b = 16
b = 8
c = b -4 = 4
The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
Answer:
The team is 8
The current is 4

The sum of three consecutive integers is 183. What are the integers?
Answer:
60, 61, 62
Step-by-step explanation:
Let's call our first integer n.
The other two, since they are consecutive, will be n+1, and n+2.
First number: n
Second number: n + 1
Third number: n + 2
The sum of these 3 will be:
[tex]n + (n+1) + (n+2)\\3n + 1 + 2\\3n + 3[/tex]
We know that the sum, 3n+3, is equal to 183. Let's set these two equal to each other and solve the equation.
[tex]3n+3 = 183[/tex]
Subtract 3 from both sides.
[tex]3n = 180[/tex]
Divide both sides by 3.
[tex]n = 60[/tex]
Now that we know n, we can find the values of all 3 integers.
First number, n:
n = 60
Second number, n+1:
n + 1 = 60 + 1 = 61
Third number, n + 2:
n + 2 = 60 + 2 = 62
Answer: 60, 61, 62
A cell tower is located 3 miles east and 4 miles north of the center of a small town. The cell tower has a coverage radius of 3 miles.
Answer:
The answer is below
Step-by-step explanation:
A cell tower is located 3 miles east and 4 miles north of the center of a small town. The cell tower has a coverage radius of 3 miles.
a) Start by drawing a diagram of this situation. Your diagram might include a coordinate plane, the cell tower, and a circle representing the cell tower's coverage boundary.
a) A house is located 5 miles north of the center of the town and is to the east of the cell tower. If the house lies on the boundary of the cell tower's coverage, how far east of the center of the town is the house?
Answer:
Let the center of the town represent the origin (0,0). Also 1 unit = 1 mile. Since the cell tower is located 3 miles east and 4 miles north of the center of a small town, it is represented by A(3, 4)
The cell tower has a coverage of radius 3 miles. This can be represented by a circle with equation:
(x - a)² + (y - b)² = r². where (a,b) is the center of the circle and r is the radius. Hence:
(x - 3)² + (y - 4)² = 3²
(x - 3)² + (y - 4)² = 9
The diagram is drawn using geogebra.
b) The house is 5 miles north. It can be represented by y = 5 line.
To find the distance east of the house we have to substitute y = 5 and solve for x, hence:
(x - 3)² + (y - 4)² = 9
(x - 3)² + (5 - 4)² = 9
(x - 3)² + 1 = 9
(x - 3)² = 8
(x - 3) = √8
x - 3 = ±2.83
x = 3 ± 2.83
x = 5.83 or 1.83
Since it is to the east to the cell tower, hence x = 5.83.
Therefore the house is located 5.83 miles to the east of the cell tower
