Answer:
they have the same batting record
Step-by-step explanation:
Batting record for each :
Neil :
9 /11 = 0.8181
Maggie :
18 /22 = 0.8181
From here we see that they both have the same proportion of hits :
Hence they have the same batting record

The volume of the cone is [tex]\frac{\pi}{4}[/tex] the volume of the pyramid
The ratio of the area is given as:
[tex]R= \frac{\pi r^2}{4r^2}[/tex]
or
[tex]R= \frac{\pi}{4}[/tex]
The volume of a cone is:
[tex]V_1 = \frac 13 \pi r^2 h[/tex]
For a pyramid, the volume is:
[tex]V_2 = \frac 43 r^2h[/tex]
Rewrite as:
[tex]V_2 = 4 * \frac 13 r^2h[/tex]
Divide by 4
[tex]\frac{V_2}{4} = \frac 13 r^2h[/tex]
Substitute [tex]\frac{V_2}{4} = \frac 13 r^2h[/tex] in [tex]V_1 = \frac 13 \pi r^2 h[/tex]
So, we have:
[tex]V_1 = \frac{V_2}{4} * \pi[/tex]
This gives
[tex]V_1 = \frac{\pi}{4} V_2[/tex]
Hence, the volume of the cone is [tex]\frac{\pi}{4}[/tex] the volume of the pyramid

A family has two cars. The first car gets 25 miles per gallon and the second car gets 15 miles per gallon. In a week the two cars went 725 miles and consumed 35 gallons of gas. How much gas did each car use?
Answer:20 and 15 gallons
Step-by-step explanation:
Given
The first car gets 25 miles per gallon
The second car gets 15 miles per gallon
Two cars consumed 35 Gallons
they went for 725 miles in total
suppose the first car consumes x gallons
so, the second car consumes 35-x gallons of gas
We can write
[tex]\Rightarrow 25x+15(35-x)=725\\\Rightarrow 25x-10x=725-525\\\Rightarrow 10x=200\\\Rightarrow x=20[/tex]
First consumed 20 gallons and second consumed 15 gallons

Step-by-step explanation:
Using basic trig for right tringles ([tex]\cos\theta =\frac{\text{adj}}{\text{hyp}}[/tex]), we have the following equation:
[tex]\cos 35^{\circ}=\frac{5}{c},\\c=\boxed{\frac{5}{\cos 35^{\circ}}}[/tex].
The value of c in the right triangle ABC is 5 / cos 35°
Right triangle:
Right triangle has one of its sides as 90 degrees. The sides of a right triangle can be found using trigonometric ratios as follows;
cos 35 = adjacent / hypotenuse
where
adjacent side = 5 inches
c = hypotenuse
Therefore,
cos 35° = 5 / c
cross multiply
c cos 35° = 5
divide both sides by cos 35°
c = 5 / cos 35°

Dan is planning an event for which the total cost cannot exceed $400. Dan plans to spend $180 on food and to hire a clown at the rate of $35 per hour. Which inequality correctly shows Dan's spending in terms of h, the number of hours that the clown can be at the party? *
Answer:
using above inequality equation, we can find the total hours in which the clown can be at the party
The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Dan is planning an event for which the total cost cannot exceed $400.
And, Dan plans to spend $180 on food and to hire a clown at the rate of $35 per hour.
Now,
Let number of hours = h
So, We can formulate;
Total spend money = $180 + $35h
Hence, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400
Thus, The correct inequality for the Dan's spending in terms of h, the number of hours that the clown can be at the party will be;
⇒ $180 + $35h < $400

in the sequence 34, 40, 37, 36, 42, 39, 38’…, what numbers should come next?
a) 44, 42 , 41
b) 43, 40, 39
c) 45, 42, 41
d) 44, 41, 40
Answer:
d) 44, 41, 40
Step-by-step explanation:
34 + 6 = 40
40 - 3 = 37
37 - 1 = 36
36 + 6 = 42
42 - 3 = 39
39 - 1 = 38
pattern: +6, -3, -1
the next pattern from -1 is +6 so we take 38 and add 6:
38 + 6 = 44
then take 44 and subtract 3 from it:
44 - 3 = 41
lastly, take 41 and subtract 1 from it:
41 - 1 = 40
Answer:
44,41,40
Step-by-step explanation:
34
34 + 6 = 40
40 - 3 = 37
37 - 1 = 36
36 + 6 = 42
42 - 3 = 39
39 -1 = 38
So, your next set of numbers are
38 + 6 = 44
44 - 3 = 41
41 - 1 = 40

Answer:
the possible line of best fit equation is;
y = 10x + 24
Step-by-step explanation:
Here, we want to get the approximate line of best fit
Mathematically, we have the general line of best fit as
y = mx + b
where m is the slope and b is the y-intercept
By joining the given lines, we can see that the y-intercept values fall a little below 30
This means that the possible y-intercept value is 24
Now, to get the slope value, we select any two points and use the slope equation
We can have (3,50) and (6,80)
Using the slope equation;
m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10
The equation is thus;
y = 10x + 24
Find the Slope-intercept equation of the line which passes through (3, -4) and (-3, 8).
Answer:
y = -2x + 2
Step-by-step explanation:
8 + 4/ -6
= -2
y = -2x + b
8 = -2(-3) + b
8 = 6 + b
2 = b
check work
-4 = -2(3) + 2
-4 = -6 + 2
-4 = -4

Answer:
El tiempo de fabricación para cada vehículo es:
Automóviles tipo Sedan= 1 hora
Camionetas tipo SUV= 1.5 horas
Camionetas tipo VAN= 2 horas
Camionetas tipo Pick-up= 3 horas
Automóviles deportivos= 12 horas

En una fábrica de automóviles que trabaja las 24 horas se arman diariamente 24 automóviles tipo Sedan, 16 camionetas tipo SUV, 12 camionetas tipo VAN, 8 Camionetas tipo Pick-up y 2 automóviles deportivos. Para calcular el tiempo de fabricación de cada vehículo debes dividir la cantidad de horas que trabaja por la cantidad de cada vehículo fabricado. Esto es:
24 horas÷ 24 automóviles tipo Sedan= 1 hora
24 horas÷ 16 camionetas tipo SUV= 1.5 horas
24 horas÷ 12 camionetas tipo VAN= 2 horas
24 horas÷ 8 Camionetas tipo Pick-up= 3 horas
