Answer:

[tex]V = \pi (2.5)^2h[/tex]

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

[tex]V = \pi (2.5)^2h[/tex]

Answer:

8( 3 + 7)

Step-by-step explanation:

I prommise this one is correct

8 is the GCF of 24 and 56

if you mutiply 3 by 8 it would equal 24

and if you mutiply 7 by 8 it would equal 56

which would leave you with 24+ 56

Answer:

8(3+7)

Step-by-step explanation:

First we list the factors of 24:

1,2,3,4,6,8,12,24

Now we list the factors of 56:

1,2,4,7,8,14,28,56

As we can see 8 is the highest number in both lists so this would mean a = 8

To factor 24+56 to 8(b+c) :

We do 24÷8 = 3 = b

and 56÷8 = 7 = c

So our final answer is 8(3+7)

Answer: question c (don’t know if it’s correct)

Step-by-step explanation:

The graph shows the time, hours, and how much it takes the rowboat to travel in 1 mile.

Answer:

Step-by-step explanation:

2.

area= length x width

area = 5.4 x 5.4 = 29.16 cm^2

perimeter is adding up all the sides

perimeter= 5.4+5.4+5.4+5.4 = 21.6 cm

1. area= 7.4 x 5.1 = 37.74 yds^2

perimeter= 7.4+7.4+5.1+5.1 = 25 yds

you have 4 fields where it can land, so the probability has a denominator 4.

2 of those fields have a even number so the numerator is 2.

-> probability is 2/4= 1/2

Answer:

The cost of the rides are 3 tickets

And 1 ticket per game

The ride and game cost 3 tickets and 1 ticket for each respectively.

Step-by-step explanation:

Step 1 of 5

Let a be the number of tickets per ride costs. And b be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, 5a+4b=19    For Isaac,  7a​+2b=23

Step 2 of 5

Multiplying the equation 2 by 2, we get  ​5a+4b=19→1  14a+4b=46→2​

Step 3 of 5

By subtracting both the equations, we get

(−)​5a+4b=1914a+4b=46​          

_____________        

−9a      =−27                  

 ​a=−27−9⇒a=3​

Step 4 of 5

Substituting the above value in the equation 1, we get​5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1​

Step 5 of 5

The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.

33%

Step-by-step explanation:

if you add the amount of penalty kicks in 4 or more, it is 33 and total of all penalty kicks is 100 so it probability is 33/100= 33%

Step-by-step explanation:

2) [tex]8\leq \frac{w}{8}[/tex]

Multiply 8 on both sides to isolate w

[tex]8\leq \frac{w}{8}\\(8)8\leq \frac{w}{8}(8)\\64\leq w[/tex]

3) [tex]18 < f-2[/tex]

Add 2 on both sides to isolate f

[tex]18 < f-2\\18 +2 < f-2+2\\20 < f[/tex]

4) [tex]\frac{y}{12} < 4[/tex]

Multiply 12 on both sides to isolate y

[tex]\frac{y}{12} < 4\\\frac{y}{12}(12) < 4(12)\\y < 48[/tex]

5) [tex]6 < r+6[/tex]

Subtract 6 from both sides to isolate r

[tex]6 < r+6\\6-6 < r+6-6\\0 < r[/tex]

6) [tex]10 > 7+x[/tex]

Subtract 7 from both sides to isolate x

[tex]10 > 7+x\\10-7 > 7-7+x\\3 > x[/tex]

7) [tex]n+1\leq 6[/tex]

Subtract 1 from both sides to isolate n

[tex]n+1\leq 6\\n+1-1\leq 6-1\\n\leq 5[/tex]

8) [tex]9x\leq 18[/tex]

Divide both sides by 9 to isolate x

[tex]9x\leq 18\\\frac{9x}{9} \leq \frac{18}{9} \\x\leq 2[/tex]

9) [tex]p+3 > 9[/tex]

Subtract both sides by 3 to isolate p

[tex]p+3 > 9\\p+3-3 > 9-3\\p > 6[/tex]

10) [tex]4\leq \frac{c}{3}[/tex]

Multiply both sides by 3 to isolate c

[tex]4\leq \frac{c}{3}\\(3)4\leq \frac{c}{3}(3)\\12\leq c[/tex]

11) [tex]k-13\leq 7[/tex]

Add 13 to both sides to isolate k

[tex]k-13\leq 7\\k-13+13\leq 7+13\\k\leq 20[/tex]

12) [tex]15 > 5x[/tex]

Divide both sides by 5 to isolate x

[tex]15 > 5x\\\frac{15}{5} > \frac{5x}{5} \\3 > x[/tex]

Answer:

c=42

Step-by-step explanation:

First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.

Hope this helps!

Answer:

C = 42

Step-by-step explanation:

½ c + 45 = 66

½ c + 45 − 45 = 66 − 45

2 × (½ c) = 2 × 21

C = 42

Answer:

28/206 or the simplest form would be 14/103

Step-by-step explanation:

Basically, you add the skull, face, and ears and you get a number which is 28 and the total of the bones is 206 if you add all of the numbers and if you want to simplify you divide both of the numbers/the numerator and denominator by 2 and you get 14/103.

The value of fraction of the bones in a typical human body are in the skull, face, and ears is,

⇒ 28 / 206

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

The table shown the bones in a typical human body.

Hence, Number of the skull, face, and ears bones is,

⇒ 8 + 14 + 6

⇒ 28

And, Total number of bones is,

⇒ 206

Thus, The value of fraction of the bones in a typical human body are in the skull, face, and ears is,

⇒ 28 / 206

#SPJ2

Answer:

Mr. Johnson completed his travel in 15 minutes. But Mrs. Johnson leaves 10 minutes after he does. And to add her 12 minutes travel time, that means Mrs. Johnson will arrive in 22minutes.

Step-by-step explanation:

First, we need to find the distance (d) that Mr. Johnson traveled to be able to compute Mrs. Johnson's travel time.

To be able to do that, use the formula d = (s)(t).

d = (80miles/hr)(15mins)

d = (80miles/hr)(0.25hr)

d = 20 miles

Now that we know the distance from Cambridge to Newton, we can use this value to calculate the time Mrs. Johnson needs to complete her travel.

Using the formula t = (d)/(s);

t = (20miles)/(100miles/hr); we get:

t = 0.2hr or 12minutes

Answer: 376.8 cm^2

Step-by-step explanation:

The formula for the surface area of a cylinder is A = 2prh +2pr^2

When:

When we substitute our values, we get the equation

A = 2(3.14)(4)(11) + 2(3.14)(4^2)

Now, we just multiply, square, and add our numbers to find A

A = 2(3.14)(4)(11) + 2(3.14)(4^2)

A = 2(3.14)(44) + 2(3.14)(16)

A = (6.28)(44) + (6.28)(16)

A = 276.32 + 100.48

A = 376.80

Because the hundredths place is a 0, we don't need to round.

A = 376.8

The unit is in centimeters. Area, and surface area by extent, are written in cm^2 (centimeters squared)

A = 376. 8 cm^2

Answer:

58 degrees

Step-by-step explanation:

It shows a square which means it is a right angle / 90 degrees. So that means because 32 degrees is already there the equation is 90 - 32 = 58 degrees.

Answer:

58 degrees

Step-by-step explanation:

A right angle is always equal to 90 degrees. So, Angle XOY (32 degrees) plus angle YOZ (x degrees) has to equal 90.

32 + x = 90

32 + x (- 32) = 90 (- 32)

x = 58

Therefore, x equals 58 degrees. I hope this was helpful! Have a lovely day!!! :D
