You can find this by using the pythagorean theorem.
The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.
The hypotenuse is the longest side, which is opposite the right angle.
The other 2 sides are the legs.
Here, the hypotenuse is BC which is 17.
AC is one leg. We are trying to find the other leg.
So you set up the equation AB^2+ 15^2 = 17^2.
This simplifies to AB^2 + 225 = 289.
AB^2 = 64.
AB = 8.
Solve the equation

None of the above
Answer:
f^2=49
Step-by-step explanation:
Consider the two functions f(x) and g(x), where f(x) = 2x and g(x) is graphed below.
Graph of g(x)
Compare the rate of change of the two functions on the interval 2 ≤ x ≤ 3.
The rate of change of the function g(x) is greater than f(x).
The rate of change of the function f(x) is greater than g(x).
The rate of change of the function f(x) and g(x) are the same.
The slope of the graph is 2 .
So the rate of change of g(x) is 2, just like f(x).
In fact, g(x) is also = 2x, just like f(x) .

Answer
50/1 6/7
Step-by-step explanation:
Greg and Marti are racing remote control cars. The race starts at t=0 and the car’s distance is measured from the start line. Both cars have a constant rate of change. Information about each of the cars during the race is shown below.
The race was over after 10 seconds. The winner of the race is defined by the person who is farthest from the start line. Whose car should be crowned the winner? Use mathematics to justify your answer.
Answer:
Marti
Step-by-step explanation:
Marti is farthest because it says that greg's car travels 13 feet but after two seconds he was at 30.7 away from the start line and marti was 2 feet in front but martyi goes faster because her car goes way more faster every second: (16.5 > 13) so: Greg is 30.7 + 13 x 10 = 160.7 | Marti: 2 + 16.5 x 10 = 167, So Marti wins the race and should be crowned the winner.

Maryam says that 287.04 rounded to 2 significant figures will be 28. Do you agree with Maryam? Explain your answer.
Answer: I do not agree because if the number in the ones place is 5 or more then the number in front of it should go up one, therefore the answer would be 29 instead of 28
Step-by-step explanation:
Marta purchased screws and nails at a hardware store. She paid $0.10 for each screw and $0.05 for each nail. She purchased 15 screws but did not count the number of nails she purchased. She paid a total of $5.20 for the screws and nails. How many nails did Marta purchase?
Answer:
104
Step-by-step explanation:
Based on the total amount spent, we can infer that the number of nails Marta purchased was 74 nails.
Marta purchased 15 screws which cost $0.10 each. The cost is therefore:
= 15 x 0.10
= $1.50
The amount spent on nails is:
= 5.20 - 1.50
= $3.70
If each nail cost $0.05, the total nails bought is:
= 3.70 / 0.05
= 74 nails
In conclusion, 74 nails were purchased.

The sum of three consecutive numbers is 519. What are the three numbers?
Answer:
El primer número llamaremos = x
El segundo número llamaremos = x + 1
El tercer número llamaremos = x + 2
Calculamos
x + (x + 1) + (x + 2) = 519
x + x + 1 + x + 2 = 519
x + x + x + 1 + 2 = 519
3x + 3 = 519
3x = 519 - 3
3x = 516
x = 516/3
x = 172
El valor de "x" lo reemplazamos en: (x + 1 y x + 2)
x + 1 = 172 + 1 = 173
x + 2 = 172 + 2 = 174
Respuesta.
Los números son: 172, 173 y 174
172 + 173 + 174 = 519

The distance traveled varies directly with the time spent in motion when speed is held constant.
If d represents the distance traveled and t represents time, which equation would represent this variation?
If you travel 150 miles in 4 hours, what is the constant of variation?
If you continue traveling at a constant speed, how long will it take to travel 200 miles? Round to the nearest tenth of
an hour.
about hours
Intro
Done
Answer:
16/3 or 5.3
Step-by-step explanation:
150 miles = 4 hours
Find how long it takes to travel 50 miles(GCF between 150 and 200)
150/3 = 4/3
50 miles = 1 1/3 hours: multiply by 4 to get 200 miles
50 x 4 = 4/3 x 4/1
200 = 16/3
16/3 hours or 5.3
How are mountains and plateaus alike?
Answer:
It is similar to a mountain in that it is dramatically higher than what is immediately around it. But mountains usually have a distinct apex or peak that is very small relative to the base and not typically level. Plateaus and mesas have tops only a little smaller than the base, and relatively flat. If the aspect ratio is less than 1, plateau. If greater than 1, mesa.

-9/8, * x - 7=-25
Answer: x=16
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-9/8*x-7-(-25)=0
simplify 9/8
((0 - (9/8 • x)) - 7) - -25 = 0
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 8 as the denominator
7 = 7/1 = 7*8/8
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
-9x - 56 = -1 • (9x + 56)
Adding up the two equivalent fractions
(-9x-56) - (-25 • 8)/8 144 - 9x/8
144 - 9x = -9 • (x - 16)
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, multiply both sides of the equation by the denominator.
Here's how:
-9•(x-16)/8 • 8 = 0 • 8
Now, on the left hand side, the 8 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-9 • (x-16) = 0
Solve : x-16 = 0
Add 16 to both sides of the equation :
x = 16
Answer: x=16
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-9/8*x-7-(-25)=0
simplify 9/8
((0 - (9/8 • x)) - 7) - -25 = 0
Subtracting a whole from a fraction

-9x - 56 = -1 • (9x + 56)
Adding up the two equivalent fractions

144 - 9x = -9 • (x - 16)
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, multiply both sides of the equation by the denominator.

Answer:
x equals 10
Step-by-step explanation:
this is a version of the 3,4,5 rule which says that if the sides of a right triangle are 3 and 4, the hypotenuse is 5. Since 6 and 8 could be simplified to 3 and 4 respectively, you could make the hypotenuse (x) 10, which has the same relationship to 5 (division by 2). Hope this helps!
