Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
Answer: Greater than 10 N
Step-by-step explanation:
Given
Gravity force on metal is 10 N
But the metal piece is rising i.e. there must be an upward force greater than 10 N
Suppose the force is F
So, we can write
[tex]\Rightarrow F>10\ N[/tex]
Any force greater than 10 N is sufficient for the metal to move upwards
The greater the amount of force faster will be the movement

just subtract the powers of 10 and 8.
The points (1, 10) and (0, 2) fall on a particular line. What is its equation in slope-
intercept form?
0) Write your answer using integers, proper fractions, and improper fractions in simplest
form.
y = x +
Answer:
y = 8x + 2
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By this formula, slope of a line passing through (1, 10) and (0, 2) will be,
m = [tex]\frac{10-2}{1-0}[/tex]
m = 8
Equation of the line will be,
y = 8x + b
Since, this line passes through (0, 2),
2 = 8(0) + b
b = 2
Therefore, equation of the line will be,
y = 8x + 2
Answer:
y=3x+2

To Find :
complete the table
calculate and estimate for the mean
The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.
a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:
Number of Nuts Number of Packets Midpoint (x) fx
4-6 5 5 5 * 3 = 15
7-9 8 8 8 * 9 = 72
10 - 12 11 11 11 * 12 = 132
13 - 15 14 14 14 * 17 = 238
16 - 18 17 17 17 * 9 = 153
Total 50 610
b) To calculate an estimate for the mean, we use the formula:
Mean = Sum of (fx) / Total Number of Packets
Mean = 610 / 50
Mean ≈ 12.2
Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

Yesterday 56 people came to the Center, How many people came to the Center to hike if: 30 people took classes,22 went bird-watching, and l2 people did both?
Answer:
40 people came to the Center to hike
Step-by-step explanation:
30 people took classes
22 did bird watching
12 did both
to solve, take 12 and subtract it from each one:
⇒ 30 - 12 = 18
⇒ 22 - 12 = 10
18 people only took classes
10 people only did bird watching
12 people did both
18 + 10 + 12 = 40

A parallelogram has an area of 20 square centimeters. The height of the triangle is 5 centimeters. What is the length of its base?
Answer:
4 cm
Step-by-step explanation:
A parallelogram area formula= Base x Height.
It already gave you the area so you can work backwards to solve for the base.
So, 20 divided by 5(the height) is 4.
Therefore, you can conclude that the length of the base is 4 cm.

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0) 1 :3
Answer:
(7, 3)
Step-by-step explanation:
Using the midpoint formula
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
X = ax1+bx2/a+b
X = -5(1)+3(11)/1+3
X = -5+33/4
X = 28/4
X = 7
Y = ay1+by2/a+b
Y = 1(12)+3(0)/1+3
Y = 12/4
Y = 3
Hence the coordinate of P is at (7, 3)
At a sale, suits were sold for $72 each. This price was 45% of a suit's original price. How much did a suit originally cost?
Answer:
$160
Step-by-step explanation:
Let the original cost of suit be x
If the suits were sold for $72 each and this price was 45% of a suit's original price, then;
72 = 45% of x
72 = 0.45x
x = 72/0.45
x = 160
Hence the original price of the suit is $160

Given circle B below, find the value of x.
(3x + 10)
(2x - 17)
Answer: 44
Step-by-step explanation:
since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).
when you work this out, you get 44 as x.
The value of x from the given figure is 44°. Therefore, option B is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.
From the given figure,
Angle at circumference is (2x-17)° and angle at center is (3x+10)°.
Now, (3x+10)°=2(2x-17)°
3x+10=4x-34
4x-3x=10+34
x=44°
Therefore, option B is the correct answer.
