Natalie is on her school's swim team. Last year, she swam the 300-meter freestyle in 3 2/3 minutes. This year she swam a shorter distance of 200-meter freestlye in 3 minutes. What is her speed for per hour for each hour for each distanc

Answers

Answer 1

Answer:

4909 m/hr

6000 m/hr

Step-by-step explanation:

Last Year :

Distance = 300 m

Time = 3 2/3 minutes

Speed per hour = distance / time

Time in hour = 11/3 ÷ 60 = 0.0611111 hour

300 / 0.0611111 = 4909.0918 m /hr

= 4909 m/hr

This year :

Distance = 200 m

Time = 3 minutes

Speed per hour = distance / time

Time in hour = 3 ÷ 60 = 0.0333333 hour

200 / 0.0333333 = 6000.0060 m /hr

= 6000 m/hr

Find the value of x

Answer:

x = 29

Step-by-step explanation:

I think this because they give you 78 degrees. The angle across from it (3x - 9) must equal 78 degrees as well. So solve as (3x - 9) = 78. 78 + 9 is 87. 87 divided by 3 is 29.

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.

Answers

Answer:

To stay within budget, she must use 4.5 gigabytes.

Step-by-step explanation:

Giving the following information:

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.

First, we need to establish the total cost formula:

Total cost= 58.5 + 4*x

x= number of gigabytes

Now, we isolate x:

76.5= 58.5 + 4x

18/4= x

4.5= x

To stay within budget, she must use 4.5 gigabytes.

Please help.

Answers

Answer:

the answer is x= 5 and y = 1.5

Answer :Value of x is 5 Value of y is 1.5Explaination :

Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.

5x - 4y = 19 (Equation No 1)x + 2y = 8 (Equation No 2)

From Equation No 2 :-

>> x + 2y = 8

>> x = 8 - 2y

In Equation No 1 :-

Substituting here the value of x which we got above as (8 - 2y).

>> 5x - 4y = 19

>> 5 (8 - 2y) - 4y = 19

>> 40 - 10y - 4y = 19

>> 40 - 14y = 19

>> -14y = 19 - 40

>> -14y = -21

>> 14y = 21

>> y = 21 / 14

>> y = 1.5

Finding out value of x :-

>> x = 8 - 2y

>> x = 8 - 2 (1.5)

>> x = 8 - 2 × 1.5

>> x = 8 - 3

>> x = 5

○=> Correct option :[tex]\color{plum}\tt\bold{(A) \: 200.96}[/tex]○=> Steps to derive correct option :

Distance from the tip to the middle of the turbine = Radius of the circular turbine

Radius of the circular turbine = 32 meters

Circumference of the circular turbine = distance the turbine will travel in one revolution

We know that :

[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]

Circumference of the circular turbine :

[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]

[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]

[tex] =\tt \frac{44}{7} \times 32[/tex]

[tex] =\tt \frac{44 \times 32}{7} [/tex]

[tex] =\tt \frac{1408}{7} [/tex]

[tex]\color{plum} =\tt 201.06 \: m[/tex]

▪︎201.06 m can be roughly rounded off to 200.96.

▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m

▪︎Therefore, the correct option is (A) 200.96

Students who don't play video games = 101°/360° * 1,619
