Answer:
Step-by-step explanation:
By triangle sum theorem,
Sum of all angles of a triangle is 180°.
m∠1 + m∠2 + m∠3 = 180°
(m∠1 + m∠3) + m∠2 = 180°
2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]
2(m∠1) = 110°
m∠1 = 55°
Therefore, m∠1 = m∠3 = 55°
Point S is on line segment RT. Given ST=3 and RT=20, determine the length RS.
Answer:
RS = 17
Step-by-step explanation:
Given S lies on RT , then
RS + ST = RT , that is
RS + 3 = 20 ( subtract 3 from both sides )
RS = 17

If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this data point?
Given:
The data point is (3,10.5).
The prediction equation is [tex]y=-6.1x+12.5[/tex].
To find:
The value of the residual for this data point.
Step-by-step explanation:
The data point is (3,10.5). So, the actual value is 10.5 at [tex]x=3[/tex].
Prediction equation is
[tex]y=-6.1x+12.5[/tex]
Putting [tex]x=3[/tex], we get
[tex]y=-6.1(3)+12.5[/tex]
[tex]y=-18.3+12.5[/tex]
[tex]y=-5.8[/tex]
The formula for residual is:
Residual = Actual value - Expected value
[tex]Residual=10.5-(-5.8)[/tex]
[tex]Residual=10.5+5.8[/tex]
[tex]Residual=16.3[/tex]
Therefore, the residual for the given data point is 16.3.

Since it's at the same time of the day, the ratio between the height of the person and the shadow they cast will stay the same. So the man's height to shadow ratio is 6:8 = 3:4. The son's height to shadow ratio would be the same so x:4 = 3:4 therefore his height is 3 feet.
What is the equation in point-slope form of the line passing through (0,5) and (-2, 11)?
Oy-5=-3(x + 2)
Oy-5= 3(x + 2)
Oy - 11 = -3(x - 2)
Oy - 11 = -3(x + 2)
Answer: y-11 = -3(x+2)

Answer:
-6
Step-by-step explanation:
To find the slope, you do y₂ - y₁ / x₂ - x₁
y₂ - y₁ / x₂ - x₁
= -35 - 11 / 5 - 1
= -24 / 4
= -6
The slope is -6
Answer:
-6
Step-by-step explanation:
Hi,
To find the slope when given a table, just pick two points, subtract the y values, and then divide them by the x values after you subtract them as well. Here's what I mean...
Let's use 1, -11 and 5, -35
So...
-35 - (-11)
This is the change in y. -35 - (-11) is the same thing as -35 + 11 (subtracting negative switches to adding it)
You get -24
Now, the change in x.
5 - 1 = 4
So, -24/4 and you get the slope of : -6

Step-by-step explanation:
A sprinkler waters a circular area. The sprinkler sprays 30 gallons of water per minute.
Select as few quadrants as possible that would allow you to create a graph of the total number of gallons of water,
y, sprayed by the sprinkler after x minutes.
Quadrant 1
Quadrant 2
Quadrant 3
Quadrant 4
Answer:
Quadrant 1
Step-by-step explanation:
The number of gallons of water sprayed after x minutes would never be negative, nor would time be negative, so the first quadrant would be all that you need

b. If each square has a side length of 61 cm, write an expression for the surface area and another for the volume of the figure
Answer:
6*(61^2) and 61^3
Step-by-step explanation:
If the squares have a side length of 61 (assuming this is a cube) our surface area is 6*(61^2) because each side is a square and there are six sides.
As for the volume, we have 61^3.
Hope this was helpful.

Choose the equation that best describes the situation below.
The Houston Rockets scored 66 points in the second half. There are 24 minutes in a half. What was their average number of points per
minute?
p=points per minute
That would just be
66/24, as there is 24 minutes in a half
66/24=2.75 points
p = 2.75 points per min
Which of the following points is not an ordered pair for the function
ƒ(x ) =5/2 x + 6?
4, 16)
(2, 7)
(-2, 1)
Answer:
2,7
Step-by-step explanation:
To solve this type of problem you simply plug the left number or x value in the ordered pair into the function and then see if it equals the right or y value. So we would plug 4 in for x and get 16, you then do the same thing for the other two pairs and find out that when you plug 2 into the equation, it does not equal 7

What is Unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
for second, 30*0.9=27
for third, 27*0.9 = 24.3
Similarly for the fifth computer,
=21.87*0.9
=19.68 minutes
Total time taken,
=30+ 27 +24.3+21.87+19.68
=122.553
=123 minutes.

Complete the equations below to show how you can use the Pythagorean theorem to find the distance between these two points
Answer:
The distance would be [tex]\sqrt{97[/tex].
Step-by-step explanation:
The least distance between them would be to draw a straight line between them.
By calculating the distance between the y values and the x values, you can calculate the distance.
y values:
|5 - 1| = 4
x values:
|6 - -3| = 9
| | = the absolute value, meaning you change the final sign to positive.
Use the Pythagorean theorem [tex]a^2 +b^2=c^2[/tex] and substitute the numbers in.
[tex]4^2 + 9^2=c^2 \\c^2 = 97\\c=\sqrt{97[/tex]
