Answer:
The height of the third bounce is 10.8 feet
Step-by-step explanation:
Let us solve the question
∵ A ball is dropped from a height of 50 feet
∵ The function f(x) = 50[tex](0.6)^{x}[/tex] gives the height in feet of each bounce
∵ x is the bounce number
∵ We need to find the height of the third bounce
∴ x = 3
→ Substitute x by 3 in the function above
∵ f(3) = 50(0.6)³
∴ f(3) = 50(0.126)
∴ f(3) = 10.8
∴ The height of the third bounce is 10.8 feet

The yellow turtle country covered 33 cm in six minutes her speed as a unit rate is blank a country walk blank in one minute
Answer:
5.5 cm/minute
Step-by-step explanation:
Given that,
The yellow turtle country covered 33 cm in six minutes.
To find unit rate, divide distance covered by the time.
Here, distance = 33 cm
Time, t = 6 minutes
[tex]R=\dfrac{33\ \text{cm}}{6\ \text{minutes}}\\\\=5.5\ \text{cm/minutes}[/tex]
Hence, the unit rate is 5.5 cm/minute. It means, Courtney covered 5.5 cm in one minute.

At a movie theater they sell hotdogs and popcorn. The first hour they sold 15 popcorns and 14 hotdogs for a total of $84. The second hour they made $99 selling 18 popcorns and 16 hotdogs. What is the price of 1 hotdog and 1 popcorn? Can anyone help please.
Answer:
1 hotdog cost $2.25
1 popcorn cost $3.5
Step-by-step explanation:
Let the price of hotdog be and that of popcorn be p
For the first hour;
15p + 14h = 84 •••• (i)
for the second hour;
18p + 16h = 99 •••••(ii)
so we want to solve these two equations simultaneously
In equation 1,
14h = 84-15p
h = (84-15p)/14
Simply insert this into equation ii
18p + 16(84-15p)/14 = 99
Multiply through by 14
252p + 1344 - 240p = 1386
1386-1344 = 252p-240p
12p = 42
p = 42/12
p = $3.5
to get cost of hotdogs;
h = (84-15p)/14
Substitute p = 3.5
h = (84-52.5)/14
h = 31.5/14
h = 2.25

Question 3 (2 points)
Use the figure below to answer the following questions. Find the measure of each angle.
Answer:
∠ 1 = 70°, ∠ 2 = 140
Step-by-step explanation:
110° and the adjacent angle inside the triangle are supplementary, then
angle = 180° - 110° = 70°
Since 2 sides of the triangle are congruent, then the triangle is isosceles
Thus the 2 base angles are congruent, then
∠ 1 = 70°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 2 is an exterior angle of the triangle, thus
∠ 2 = 70° + 70° = 140°

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²Step-by-step explanation:
Step 1: Identify Variables
Leg a = x
Leg b = 5
Hypotenuse c = 13
Step 2: Solve for x
Substitute [PT]: x² + 5² = 13²Isolate x term: x² = 13² - 5²Exponents: x² = 169 - 25Subtract: x² = 144Isolate x: x = 12If the temperature outside increases by 3 1/2 degrees every 1 1/2 hours, by how much will the temperature increase after 4 hours?
please answer in fractions.
Part 1:
What is the rate per hour of the temperature increase?
Part 2:
How much will the temperature increase after 4 hours?
Answer:
Part 1: 7/3 degrees/hour
Part 2: 28/3 degrees
Step-by-step explanation:
Part 1:
3 1/2 degrees per 1 1/2 hours =
= (3 1/2)/(1 1/2)
= (7/2) / (3/2)
= 7/2 * 2/3
= 7/3 degrees/hour
The rate is 7/3 degree per hour
Part 2:
In 4 hours, the temperature goes up 4 times what it goes up in 1 hour.
4 hours * 7/3 degree/hour = 28/3 degrees

Lindsey Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 864 points. The number of two-point field goals that Lindsey made was 62 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 30 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.
Answer:
Number of 3 point goals = 85
Number of 2 point goals = 3(85) - 62 = 193
Number of free throws = 3(85)- 32 = 223
Step-by-step explanation:
Given that :
2 point goals
Number of 3 point goals = x
Number of 2 point goals = 3x - 62
Number of free throws = 3x - 62 - 30 = 3x - 32
3x + 2(3x - 62)+ 3x - 32= 864.
3x + 6x - 124 + 3x - 32 = 864
12x = 864+ 124 + 32
12x =1020
x = 1020 / 12
x = 85
Number of 3 point goals = 85
Number of 2 point goals = 3(85) - 62 = 193
Number of free throws = 3(85)- 32 = 223
Triangles J K L and M N R are shown.
In the diagram, ∠J ≅ ∠M and JL ≅ MR. What additional information is needed to show ΔJKL ≅ △MNR by SAS?
KL ≅ NR
∠L ≅ ∠R
∠K ≅ ∠N
JK ≅ MN
Answer:
JK ≅ MN
Step-by-step explanation:
SAS states that any two sides of the angle and the angle itself, if , of two triangles are equal the two triangles are equal.
It is given that ∠J ≅ ∠M and JL ≅ MR i.e an angle and a side are equal. We need one more side to prove that the two triangles are equal.
If we look at the diagram closely we see that the angles J and M are formed by the sides JK & JL and MN& MR.
It is given that JL ≅ MR so we are left with JK ≅ MN
The additional information needed prove that ΔJKL ≅ ΔMNR by SAS Congruence Theorem is: D. JK ≅ MN
Recall:
The SAS Congruence Theorem proves that two triangles are congruent to each other if they have two pairs of congruent sides and a pair of included congruent angles.The image attached below shows ΔJKL and ΔMNR where we are given the following:
∠J ≅ ∠M (one pair of congruent angles).
JL ≅ MR (one pair of congruent sides).
Therefore, the additional information needed prove that ΔJKL ≅ ΔMNR by SAS Congruence Theorem is: D. JK ≅ MN

Step-by-step explanation:
let 'm' be mid value of class and 'L' be upper limit in frequency table. The lower limit of class is ? Please prove and answer
Answer:
Lower Limit = 2m-L
Step-by-step explanation:
Given that,
The mid value of class = m
Upper limit in the frequency table = L
We need to find the lower limit of the class.
The mid value of a class is given by :
[tex]\text{mid-value}=\dfrac{\text{lower limit + upper limit}}{2}\\\\m=\dfrac{L+\text{lower limit}}{2}\\\\2m=L+\text{lower limit}\\\\\text{lower limit}=2m-L[/tex]
Hence, the lower limit of the class is 2m-L.

Answer:
[tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Step-by-step explanation:
In this question, we need to simplify [tex]8x-5+2x\dfrac{x}{y}[/tex]
We can convert elements to fractions.
[tex]8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}[/tex]
= [tex]\dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}[/tex]
As the denominators are equal, we can combine the fractions as follows :
=[tex]\dfrac{8xy-5y+2x^2}{y}[/tex]
Hence, the simplified form is : [tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Given the figure above find the value of x and z
Answer:
x = 4, z = 77
Step-by-step explanation:
From the figure attached,
(15x + 43)° = (8x + 71)° [Vertically opposite angles]
15x - 8x = 71 - 43
7x = 28
x = 4
Therefore, (15x + 43)° = (15×4 + 43)°
= 103°
Now, z° + (15x + 43)° = 180° [Linear pair of angles]
z° + 103° = 180°
z° = 180 - 103
z = 77
Therefore, x = 4 and z = 77 is the answer.
