Find the distance between GH
Answer:
4.2 cm
Step-by-step explanation:
The red mark between each points in the line segment shows that FG, GH, HJ, and JK are all equal in proportion. Since all 4 segments are of equal distance, the distance of any of the segments would be: [tex] \frac{16.8}{4} = 4.2 [/tex].
Therefore, distance between GH is 4.2 cm.
Why is the equation for Newton's Law of Gravitation negative?
a. The negative sign indicates the force is made by mass
b. The negative sign cancels out the negative sign of the gravitational constant
c. The negative sign indicates the strength of the force
d. The negative sign indicates that the force is always attractive (THIS ANSWER IS CORRECT)
Answer:
gravitational force of attraction between two positive mask or two negative mass and repulsive between one negative into positive minus negative sign only appears when the force is acting in the opposite direction when considered the direction.
Answer:
D) The negative sign indicated the force is always attractive

A local business does $1200 in sales on Monday and $1400 dollars in sales on Tuesday. Which of the following a correct sentence to describe the ratio of Monday to Tuesday?
Answer: The amount of money that he made on Monday is 0.86 times the amount of money that he made on Tuesday
Step-by-step explanation:
We know:
Monday = $1200
Tuesday = $1400
Now we want to know the ratio of Monday to Tuesday, that is a relation that directly relates both quantities, we can calculate it as:
Ratio from Monday to Tuesday = Monday/Tuesday = $1200/$1400 = 0.86
Then the amount of money that he made on Monday is 0.86 times the amount of money that he made on Tuesday
What are rational numbers
Answer:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs?
A) Choose the equation to match the situation.
A. (0.20)(10) = 0.05x + 0.40x
B. (0.20)(10) = 0.05x + 0.40(10 – x)
C. (0.20)(10) = 0.05(10) + 0.40(10 – x)
D. (0.20)(10) = 0.05(10 – x) + 0.40(10 – x)
B) Solution
??? liters of 5%
??? liters of 40%

A circle is centered at the origin (0,0) and has a radius of 4 units. Which points on the circle have an x-coordinate of 1? (Your answer should be a list of points, such as "(1,1), (2,4)".)
Answer: (1, √15) and (1, -√15)
Step-by-step explanation:
A circle centered at the point (a, b) of radius R can be written as:
(x - a)^2 + (y - b)^2 = R^2
In this case we have:
"A circle is centered at the origin (0,0) and has a radius of 4 units"
Then the equation for this circle is:
x^2 + y^2 = 4^2 = 16.
Now, we want to find the points where x = 1, then we can replace that value and solve the equation for y.
1^2 + y^2 = 16
1 + y^2 = 16
y^2 = 16 - 1 = 15
y = +-√15
Then the two points that have the x-coordinate equal to 1 are:
(1, √15) and (1, -√15)
The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)
The equation of a circle usually takes the form;
(x-a)² + (y-b)² = r²where a and b are x- and y- coordinates of the center of the circle.
In this scenario, the center is at the origin (0,0).
In essence, the points on the circle which have an x-coordinate of 1 can be evaluated as follows;
(1-0)² + (y - 0)² = 4²1 + y² = 16.y² = 15y = ±√15.The points on the circle which have an x-coordinate of 1 are:. (1,+√15) and (1,-√15)

g The distribution of heights of 7-year-old girls is approximately normally distributed with a mean of 47.7 inches and a standard deviation of 2.4 inches. Amy is 7 years old, and her height is 1.34 standard deviations above the mean. Her friend Sophia is also 7 years old and is at the 94th percentile of the height distribution. a. At what percentile is Amy's height? Draw and label the Normal model that corresponds to this situation. b. How does her height compare to Sophia's? c. What percent of 7-year-old girls would you expect to be taller than 49.4 inches? Draw and label the Normal model that corresponds to this situation. d. Below what height are the shortest 30% of 7-year-old girls? Draw and label the Normal model that corresponds to this situation.
Answer:
a) 90th percentile
b) X = 51.43 ( Sophia's height ) , Amy's height = 50.92
c) 0.2394
d) 46.44 inches
Step-by-step explanation:
mean value( u ) = 47.7 inches
std ( σ )= 2.4 inches
Amy height = 1.34 std above mean value
Sophia height = 94th percentile of height distribution
A ) what percentile is Amy's height
To Calculate the percentile of Amy's height
P( X ≤ 50.916 ) = P( (X-µ)/σ ) ≤ (50.916-47.7) /2.4)
=P(Z ≤ 1.340 ) = 0.9099 = 90th percentile
B) How Amy's height compare to Sophia's
The proportion given based on Sophia's height = 0.94
z -value at the proportion ( 0.94 ) = 1.55 ( from excel )
note z-value can be calculated using = ( x - µ ) / σ
therefore: X (Sophia's height ) = zσ + µ= (1.55 * 2.4) + 47.7
X = 51.43 ( Sophia's height ) , Amy's height = 50.92
C) percentage expected to be taller than 49.4 inches
P ( X ≥ 49.40 ) = P( (X-µ)/σ) ≥ (49.4-47.7) / 2.4)
= P(Z ≥ 0.708 )
= P( Z < -0.708 )
= 0.2394
D) Below what height are the shortest 30% of 7-year old girls
( u ) = 47.7 inches
std ( σ )= 2.4 inches
given proportion = 30% = 0.3
The z value at 0.3 = -0.52 ( from excel )
to calculate for X ( height ) we have to apply the formula used to determine z value
z= (x-µ) /σ
hence : X = (Z * σ) + u = (-0.52 * 2.4 ) + 47.7
X = 46.44
below 46.44 inches lies about 30% of 7 year old girls height
What’s the explicit rule for the sequence 9,14,24,...
Answer:
f(n) = 5n(n -1)/2 +9
Step-by-step explanation:
The rule will depend on what kind of sequence you think this is. An infinite number of rules can be dreamed up that will give these three values.
The simplest polynomial rule is one of 2nd degree. We know this because the first differences are 14-9 = 5 and 24-14 = 10, so are not constant. Only three values are given, so only a polynomial of degree 3-1=2 can be specified by these points.
If we say the polynomial is ...
f(n) = an^2 +bn +c
Then the three given points give rise to three equations:
9 = a + b + c
14 = 4a +2b +c
24 = 9a +3b +c
Solving these by your favorite method gives ...
a = 5/2, b = -5/2, c = 9
So an explicit polynomial rule can be written as ...
f(n) = 5n(n -1)/2 +9
_____
Additional comment
A sequence such as this one can also be described by an exponential rule. Here's one that describes these points:
f(n) = 5·2^(n-1) +4
The fact that the first differences (5, 10) are related by a factor of 2 suggests 2 as the base of the exponent.
ABCD IS A SQUARE WITH LENGTHS OF 35 INCHES GIVEN THAT AG=14 AND FG=24 WHAT IS THE LENGTH OF EG
Answer:
EG = 16
Step-by-step explanation:
Given: all sides have length 35 inches.
AG + GD = AD
14 + GD = 35
GD = 21
Angles A and D are right angles and are congruent.
Angles AEG and DFG are marked congruent in the figure.
By AA Similarity, triangles EAG and FDG are similar.
The lengths of corresponding sides of similar triangles are proportional.
EG/AG = FG/GD
EG/14 = 24/21
EG/14 = 8/7
7(EG) = 14(8)
EG = 2 * 8
EG = 16
