1. Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes.
Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls
does Cadence have?
Answer:
Cadence has 18 more green eyed dolls
Step-by-step explanation:
1. 52-16=36
2. 36÷2=18
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Rhythm has an assortment of 52 dolls that all have either blue-eyes or green-eyes. Rhythm has 16 additional blue-looked-at dolls than green-peered dolls.
Let 'x' be the number of blue-eyes dolls and 'y' be the number of green-eyes dolls. Then the equations are given as,
x + y = 52 ...1
x = y + 16 ...2
From equations 1 and 2, then we have
y + 16 + y = 52
2y = 52 - 16
y = 36 / 2
y = 18
The value of x is given as,
x = 18 + 16
x = 34
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.

Answer:
Step-by-step explanation:
The equation is a parabola, that opens up downwards, and the point from which Sarah throws the ball is 5 feet off the ground. so set the height to zero ( when the ball reaches the ground ) and solve for t
0 = -16[tex]t^{2}[/tex] + 18t + 5
use quadratic equation :)
-b +- sqrt([tex]b^{2}[/tex] - 4ac) / 2a
-18 +- sqrt[ [tex]18^{2}[/tex] - 4 (-16)(5) ] / 2(-16)
-18 +- sqrt[324 +320 ] / -32
-18 +- sqrt[644] / -32
-18 +- 25.377155 / -32
do the positive choice :
-18 + 25.377155 / -32
7.377155 / -32
-0.2305 ( so this answer would be where the ball would hit the ground if the arc extended down to the ground behind where Sarah throws the ball from. so this answer doesn't count in our domain. Because it's before Sarah throws the ball)
do the negative choice:
-18 - 25.377155 / -32
1.355536 ( this answer looks good, about 1.35 seconds for the ball to fly , this was more of a toss than a throw. )
t = 1.4 seconds ( rounded to nearest 10th )

A cylinder with radius 6 cm and height h cm has the same volume as a sphere with radius 4.5cm
Find the value of h.
(The volume, V, of a sphere with radius r is V=4/3pie r^3)
Answer:
h = 4.22 cm
Step-by-step explanation:
Mathematically, we have the volume of a cylinder as;
V = pie * r^2 * h
We have it that the radius is 6 cm
V = pie * 6^2 * h
for the sphere, we have it that;
V = 4/3 * pie * r^3
V = 4/3 * pie * 4.5^3
We can proceed to equate both volumes;
pie * 6^2 * h = 5/3 * pie * 4.5^3
pie on both sides cancel out
6^2h = 5/3 * 4.5^3
36h = 151.875
h = 151.875/36
h = 4.22 cm

Answer:
Step-by-step explanation:
since RS || VU ( parallel to ) then the angle V is equal to ∠ VRS , also we are given that ∠VRT = 71° so subtract ∠VRT from ∠VRS
103° - 71° = 32°
so ∠TRS = 32°
next find ∠U, we know that ∠U + ∠VRT= 180° ( b/c they are supplementary )
we are also told that ∠VRT = 71°
∠U = 180 - 71
∠U = 109°
Since RS || VU (parallel to) then the angle V is equal to VRS, also we are given that VRT = 71°
So subtract VRT from VRS,
103° -71° = 32°
So, TRS = 32°
next find U, we know that ZU + ZVRT= 180° (b/c they are supplementary)
We are also told that <VRT = 71"
U = 180° - 71°
U = 109° is the answer.

Step-by-step explanation: Do You Want Me To Find All The Values ?
Parallel lines intersected by a common transversal form 8 angles
The required values of y and x are;
5. y = 42°6. y = 29.5°7. y = 9°8. y = 14°9. y = 31°10. x = 20°11. x = 13°12. y = 39°The reasons why the above values are correct are given as follows:
Given the lines are parallel lines cut by a common transversal, we have;
Angles with measure (2·y - 1)° and (9·x - 38)° are same side interior angles
Angles with measure (4·x + 23)° and (2·y - 1)° are alternate interior angles
Which gives;
(2·y - 1)°+ (9·x - 38)° = 180°...(1)
(4·x + 23)° = (2·y - 1)°...(2)
From equation (1), we get;
y = 109.5 - 4.5·x
From equation (2), we get;
y = 2·x + 12
The common solution is given by; 109.5 - 4.5·x = 2·x + 12
From 109.5 - 4.5·x = 2·x + 12, we get;
x = 15,
y = 42°6) (9·x + 42)° and 15·x° are vertical angles, and therefore are equal
(9·x + 42)° = 15·x°
∴ x = 7
(4·y - 13)° and (9·x + 42)° are supplementary, therefore
(4·y - 13)° = (9·x + 42)°, which gives;
(4·y - 13)° = (9×7 + 42)° = 105°
y = 29.5°7) (3x + 11) + (x + 21) = 180
∴ x = 37
(14·y - 4)° = 3x + 11 = 3 × 37 + 11 = 122°
y = 9°8) (13·x - 33) = 10·x
∴ x = 11
10·x + 5·y = 180
10 × 11 + 5·y = 180
[tex]y = \dfrac{70^{\circ}}{5} = 14^{\circ}[/tex]
y = 14°9) (27·x + 4) + (8·x + 1) = 180
∴ x = 5
y + 10 = 8·x + 1 = 8 × 5 + 1 = 41
y = 41 - 10 = 31
y = 31°10) 16·x - 4 = 9·x - 6 + 58 = 9·x + 52
7·x = 56
x = 8
11) (6·x - 58)° + (x + 8)° = 90°
7·x - 50 = 90
7·x = 90 + 50 = 140
[tex]x = \dfrac{140}{7} = 20[/tex]
x = 20°12) 7·x - 7 = 3·x + 45°
4·x = 52
[tex]x = \dfrac{52}{4} = 13[/tex]
x = 13°
(3·x + 45)° + 63° + (y - 6)° = 180°
(3×13 + 45)° + 63° + (y - 6)° = 180°
147 + (y - 6)° = 180°

2. Mr. Bowen’s test is normally distributed with a mean of 75 and a standard deviation of 3 points. Part A: What is the probability that a randomly selected score is greater than 81 points? Part B: What percentage of students scores are between 69 and 78? Part C: A student who scores a 84 is in the _______________ percentile.
Using the normal distribution, it is found that:
A. There is a 0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.
B. 81.85% of students scores are between 69 and 78.
C. The student scored in the 99.87th percentile.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, as:
[tex]\mu = 75, \sigma = 3[/tex].
Item a:
The probability is one subtracted by the p-value of Z when X = 81, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{81 - 75}{3}[/tex]
Z = 2.
Z = 2 has a p-value of 0.9772.
1 - 0.9772 = 0.0228.
0.0228 = 2.28% probability that a randomly selected score is greater than 81 points.
Item b:
The proportion is the p-value of Z when X = 78 subtracted by the p-value of Z when X = 69, hence:
X = 78:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{78 - 75}{3}[/tex]
Z = 1.
Z = 1 has a p-value of 0.8413.
X = 69:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{69 - 75}{3}[/tex]
Z = -2.
Z = -2 has a p-value of 0.0228.
0.8413 - 0.0228 = 0.8185.
81.85% of students scores are between 69 and 78.
Item c:
The percentile is the p-value of Z when X = 84, multiplied by 100, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{84- 75}{3}[/tex]
Z = 3.
Z = 3 has a p-value of 0.9987.
The student scored in the 99.87th percentile.
