Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: [tex]12=a*2+(7*2)+2[/tex]
Then, solve:
[tex]12=a*2+14+2[/tex]
a = -2
So yes, they're on the graph.
Hope this helped! :)
A 43-foot ladder is leaning against a building and forms a 29.37° angle with the ground. How far away from the building is the base of the ladder? Round your answer to the nearest hundredth. 21.09 feet 24.20 feet 37.47 feet 49.34 feet
Answer:
37.47 feets
Step-by-step explanation:
Using trigonometry:
The distance of wall from base of ladder is (x) :
Cosine θ = adjacent / hypotenus
Length of ladder = hypotenus ; x = adjacent
Cos 29.37 = x / 43
x = 43 * cos 29.37
x = 43 * 0.8714707
x = 37.473241
x = 37.47
Answer:
37.47 feet

setting 7/3 equal to whuch ratio would result in a valid proportion 9/49 18/42 49/9
Answer:
49/9
Step-by-step explanation:
7/3 = 49/9
What do we multiply to the 7 in the numerator by to get 49?
- Well, 7. So we know the numerators have a factor of 7.
Then what do you multiply to 3 to get 9?
-This is 3.
We notice a pattern of the number multiplying itself, so the first fraction being (7/3)^2 would be 49/9

Which best describes the triangle?
Answer: acute and isosceles
Step-by-step explanation: Notice that the triangle shown here has no right angles and no obtuse angles, which means that all of the angles of the triangle are acute. When classifying triangles, if all of the angles of the triangle are acute, then the triangle is acute.
Now, notice that two sides of the triangle have the same length.
If two sides of a triangle have the same length,
then we say that the triangle is isosceles.
So this triangle is acute and isosceles.

Step-by-step explanation: It has a total of 28 'x's so 28 x 50 = 1400
1400 divided by 7 ( Cause of the one week) is 200. if I figure out what the actual answer is I will tell you. Also be sure to read the comments.
Answer: The answer is the bottom one to the left
Step-by-step Explanation:
The sum of all the X's are 28 and if you divided that by 7 it is 4, and 4 times 50 is 200. And the highest number, which is 7, minus the smallest number which is 1 will be 6 and that times 50 is 300

Jean is multiplying 6 x 39. She decides to multiply 6 x 30 first, then add on 6 x 9. What property is Jean using to solve the problem? Her procedure would look like this mathematically
Answer:
Jean would add both results to get the final result of the multiplication of 6 x 39.
Step-by-step explanation:
6 x39 = 234
if the 3 in 39 is in the tenth position, then 6 x30 = 180
the number 9 in 39 stands as just 9, so, 6 x 9 = 54
The final multiplication of 6 and 39 = 180 + 54 = 234

Answer:
2:20 pm
Step-by-step explanation:

How many solutions exist for the system of equations below?
(3x+y=18
(3x+y=16
none
one
two
infinitely many
Step-by-step explanation:
3x + y = 18 and 3x + y = 16
=> 18 = 3x + y = 16.
However the equality 18 = 16 is false for any real values of x and y. Hence there are no real solutions.
Answer:
A. none
Step-by-step explanation:
If a,b and c are the sides of a triangle
where a = 6, b = 8 and c = 9
is this a right triangle ?
Answer:
No, it is not a right triangleStep-by-step explanation:
A right triangle consists of hypotenuse, opposite and adjacent. For the sides to be a right angle, the r=square of the longest side (hypotenuse) must be equal to the sum of the square of the other two sides
Given the sides a = 6, b = 8 and c = 9
a²+ b² = c² (This equation must be satisfied)
Taking the sum of the square of a and b
6² + 8²
= 36 + 64
= 100
= 10²
Since the result is not the square of 9 which is the third side, hence the sides is not a right triangle
Using the formula Distance = rate . time, find the distance covered by an airplane flying at 300 mph for 3 hours.

it takes 2 painters 5 hours to finish painting a house. how long would it take to finish painting a house if there were 20 painters working at the same rate?
Answer:
2 2/9 hours
Step-by-step explanation:
Im pretty Sure Its Correct
20 painters will use 0.5 hours to paint the same house at the same rate it takes 2 painters 5 hours to finish the house.
Let's find how long it take:It takes 2 painters 5 hours to finish painting a house.
For 20 painters to paint the same work at the same rate, this means the time used to conclude the work will drastically reduced.
Therefore,
if 2 painters uses 5 hours
At the same rate, 20 painters will use = 2 × 5 / 20 = 10 / 20 = 1 / 2 = 0.5 hours.
