Answer:
your answer is 9.7 feet
Step-by-step explanation:
you apply Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex] since you are looking for height you can subsitute x for a or b and since 12 is the largest number this will be your c which is your hypotneuse and 7 will be subsituted as a or b depending on what letter you used as your x value [tex]7^{2} +b^{2} =`12^{2}[/tex] is equal too 49 +b^2 =144 you then subtract 49 on both sides to isolate your x (b) and this gets you 95 and then you find the square root of 95 which is 9.7

what are the values of a, b and c in the quadratic equation -2x2+4x -3=0
Answer:
a = - 2, b = 4, c = - 3
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 ( a ≠ 0 )
Compare - 2x² + 4x - 3 = 0 to the standard, giving
a = - 2, b = 4, c = - 3
Answer:
See below in bold.
Step-by-step explanation:
-2x^2 + 4x - 3 = 0 Compare this with the standard form:
ax^2 + bx + c = 0
We see that a = -2, b = 4 and c = -3.

A rectangle has a perimeter of 12 centimeters and a height of 5 centimeters. What is the length of the base?
Answer:
1 cm
Step-by-step explanation:
We know that the formula for perimeter is 2(l+w) or l+l+w+w
We know that the height is 5 cm so that means w= 5 also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is 1 cm if you add the length together you 2 when you add the width you get 10. 10+2=12.
, she earned $62 for working with 8 students. Lisa is also a skating instructor. She receives half the base amount that Mary does, but she is paid twice as much per student. Who would earn more money instructing a class of 20 students?
Answer:
since lisa earns half of what mary does divide 62 into 2 which is 31
and she has 8 students.
she is paid twice as much in students, so lisa would earn more due to getting paid more with having more students, as she gets paid twice the amount from students she has, and if she had 20 she would get paid 40 but if you add 2x of the mass it will be 80, and mary will have 40.
if its incorrect i apologize.

Find the volume of the figure. Round to the nearest tenth if necessary.
Answer:
90 yd's
Step-by-step explanation:
Volume= L * W * H
We know that the length is 10 yd's,
the width is 3 yd's and the height is 3 yd's
so.. You do 10*3*3= 30*3= 90 yd's
What is the perimeter of this shape?
Answer:
56 cm
Step-by-step explanation:
perimeter = the length of the sides.
4+5+5+5+4+10+13+10=56 cm
Answer:
56 cm
Step-by-step explanation:
The perimeter of a shape is just all the lengths added together. So 5+5+5= 15 and 10+10+13=33 and 4+4=8. 15+33+8=56. Hence 56 is the answer

Answer:
x > 0
Step-by-step explanation:
Division by zero is not defined. Therefore, x must be greater than zero. Also: The square root function is defined only for x greater than zero or equal to zero. Together these restrictions tell us that the domain is (0, infinity ).

Steven’s hourly pay is $3 more than Mark’s. Last Friday Steven worked 5 hours, Mark worked 6 hours. Together they earned $147. What are their respective wages and how much did each earn?
(please show all your work (Let, So, Equation and Solution and Therefore Statement)
Answer:
Mark makes $12 an hour. Steven makes $15 an hour.
Step-by-step explanation:
s = steven's hourly pay
m = mark's hourly pay
s = m + 3
5s + 6m = $147
5 (m + 3) + 6m = $147
5m + 15 + 6m = $147
11m = $132
m = $12
s = m + 3
s = 12 + 3
s = $15

Use the Pythagorean Theorem to determine if a triangle with sides 15 cm, 7 cm, and 16 cm is a right triangle.
Answer:
It is not.
Step-by-step explanation:
[tex]15^{2}[/tex]+[tex]7^{2}[/tex]=225+49=274
[tex]16^{2}[/tex]=256
274≠256
Answer:
No, this triangle is not a right triangle
Step-by-step explanation:
If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem. Otherwise it is not.
15^2 + 7^2 = 225 + 49 = 1225 = 35^2. This is FALSE, and so:
No, this triangle is not a right triangle
Can one please help me with this question
Answer:
254.34 cm^2
Step-by-step explanation:
Volume of cylinder = [tex]\pi r^{2} h[/tex]
We know that the diameter is 6, which means that the radius is 3 cm.
Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.
Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.
Substituting into the formula we will end up with 254.34 cm^2.
Multiply. Write the result in the scientific notation.(1.1•10^-5)(3•10^-2)

what is the value of x in the equation below 160-15x=120+5x
So the right answer is 2.
look at the attached picture
Hope it will help you
Good luck on your assignment
Answer:
x = 2
Step-by-step explanation:
160 - 15x = 120 + 5x
160 - 120 - 15x = 120 - 120 + 5x
40 - 15x + 15x = 5x + 15x
40 = 20x
2 = x
x= 2

4(x + 6) = 32 What is x?
Answer: x = 2
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4(x) which is 4x and 4(6) which is 24.
So our equation now reads 4x + 24 = 32.
Solving from here, we subtract 24 from both sides to get 4x = 8.
Then divide both sides by 4 to get x = 2.
Two trains leave a town at the same time heading in opposite directions. One train is traveling 12 mph faster than the other.
After two hours, they are 232 miles apart. What is the average speed of each train?
Answer:
Step-by-step explanation:
I'm going to paint you a picture in words of what this looks like on paper. We have a train leaving from a point on your paper heading straight west. We have another train leaving from the same point on your paper heading straight east. This is the "opposite directions" that your problem gives you.
Now let's make a table:
distance = rate * time
Train 1
Train 2
We will fill in this table from the info in the problem then refer back to our drawing. It says that one train is traveling 12 mph faster than the other train. We don't know how fast "the other train" is going, so let's call that rate r. If the first train is travelin 12 mph faster, that rate is r + 12. Let's put that into the table
distance = rate * time
Train 1 r
Train 2 (r + 12)
Then it says "after 2 hours", so the time for both trains is 2 hours:
distance = rate * time
Train 1 r * 2
Train 2 (r + 12) * 2
Since distance = rate * time, the distance (or length of the arrow pointing straight west) for Train 1 is 2r. The distance (or length of the arrow pointing straight east) for Train 2 is 2(r + 12) which is 2r + 24. The distance between them (which is also the length of the whole entire arrow) is 232. Thus:
2r + 2r + 24 = 232 and
4r = 208 so
r = 52
This means that Train 1 is traveling 52 mph and Train 2 is traveling 12 miles per hour faster than that at 64 mph
