Answer:

Nora Won

Step-by-step explanation:

In a swimming contest you would go for the least time, so, let's see who had the least time:

20 = 20 (Tens places)

5 = 5 (Unit place)

0 < 4 (Tenths place)

So, Nora was the winner and she was faster than Rachel by 0.36 seconds

Hope it helps

Answer:

x = 63°

it is an isosceles triangle, so K and M are equal

Step-by-step explanation:

let K be x, since K=M means both equals x

x + x + 54° = 180°

2x + 54° = 180°

2x = 180° minus 54°

2x = 126°

x = 63°

to prove

63° + 63° + 54° = 180°

Answer:

arc AB = 12.40°

Step-by-step explanation:

diameter = 7.9 x 2 = 15.8

circumference = 15.8 x 3.14 = 49.612

since the central angle of arc AB is 90 °

90/360 x 49.612 = 12.40

Answer: It's A.

Step-by-step explanation:

I did the test and I got it right

The expression should be described option A. A) 13 more than half of 6 more than the quotient of 6 and 2

Since the expression is  13 + fraction 1/2 x (6 ÷ 2 + 6)

So we can explained that 13 should be more than the half of 6 i.e. more than the quotient of 6 and 2.

Therefore, the option A is correct.

And, the rest of the options are wrong.

The question is incomplete. The complete question is :

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula. Compound Interest Accounts Name Principal Interest Rate Number of Years Compounded Jaina $300 7% 3 Once a year Tomas $400 4% 3 Once a year. Which pair of equations would correctly calculate their compound interests?

Solution :

It is given that Jaina and Tomas wants to open an account by depositing a principal amount for a period of 3 years and wanted to calculate the amount they will have using the compound interest formula.

So for Jiana :

Principal, P = $300

Rate of interest, r = 7%

Time, t = 3

Compounded yearly

Therefore, using compound interest formula, we get

[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]

   [tex]$=300\left(1+\frac{7}{100}\right)^{3}$[/tex]

   [tex]$=300(1+0.07)^3$[/tex]

Now for Tomas :

Principal, P = $400

Rate of interest, r = 4%

Time, t = 3

Compounded yearly

Therefore, using compound interest formula, we get

[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]

   [tex]$=400\left(1+\frac{4}{100}\right)^{3}$[/tex]

   [tex]$=400(1+0.04)^3$[/tex]

Therefore, the pair of equations that would correctly calculate the compound interests for Jaina is [tex]$A=300(1+0.07)^3$[/tex] .

And the pair of equations that would correctly calculate the compound interests for Tomas is [tex]$A=400(1+0.04)^3$[/tex] .

Answer:

12.5 sq units. Explanation: Area of a triangle with vertices (x1,y1),(x2,y2),(x3,y3) is 12[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)]. Using this formula ...

Step-by-step explanation:

you have to study

The value of the area of circle is,

Area = 15 units²

And, The value of perimeter is,

⇒ 6 + √34 + 5√2 Units

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle with vertices A(4, 3) B(-2, 3) and C(-1, - 2).

Now, We know that;

Area of triangle with vertices (x₁, y₁) (x₂, y₂) and (x₃, y₃) is,

= 1/2 [ x₁ (y₂ - y₃) + x₂ (y₃ - y₁) + x₃(y₁ - y₂) ]

Hence, We get;

The value of the area of circle is,

Area = 1/2 [ 4 (3 + 2) - 2 (- 2 - 3) - 1 (3 - 3) ]

Area = 1/2 [ 20 + 10 ]

Area = 1/2 x 30

Area = 15 units²

We know that;

The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, Lenght of AB is,

AB = √ (- 2 - 4)² + (3 - 3)²

AB = √- 6²

AB = 6

BC = √ (- 2 - 1)² + (3 + 2)²

BC = √9 + 25

BC = √34

CA = √ (- 1 - 4)² + (- 2 - 3)²

CA = √25 + 25

CA = √ 50

CA = 5√2

Thus, The perimeter of triangle is,

⇒ AB + BC + CA

⇒ 6 + √34 + 5√2

Step-by-step explanation:

Answer:

multiply 6 by 19 to get the total age of the six people in the room then add the ages of the 5 people in the room and subtract it from the total of the 6 to get your answer

Answer:

27

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

let x be the age of the person entering the room , then

[tex]\frac{23+20+15+12+17+x}{6}[/tex] = 19 ( multiply both sides by 6 )

87 + x = 114 ( subtract 87 from both sides )

x = 27

The age of the person who entered the room is 27

Mon: 0.6x100= 60 cents

Tue: 0.6x130= 78 cents

Wed: 0.6x145= 87 cents

Thurs: 0.6x138= 82.8 cents

Fri: 0.6x210= 126 cents

60+78+87+82.8+126= 433.8 cents

Step-by-step explanation:

here's your solution

=> x= 8

=> y= -3

=> putting the value

=> 8*6 - (8*-3)

=> 48 + 24

=> 72

hope it helps

Hey there!

If x = 8 and y = -3, then SUBSTITUTE it into the equation

6(8) - 8(-3)

6(8) = 48

48 - 8(-3)

8(-3) = -24

48 - (-24)

- & - = +

48 + 24 = 72

Answer: 72

Find the change between the first two sets:

12-9 = 3

14.4 - 10.8 = 3.6

3.6/3 = 1.2

Now find the change between the last two sets:

12 - -3 = 15

14.4 - 3.6 = 10.8

10.8/15 = 0.72

1.2 does not equal 0.72 so the answer is No

Answer:

= 3 to 7

= 3 : 7

= 3/7

Step-by-step explanation:

Number of people who ride the tram = 3

Number of people who does not ride the tram = 4

Total people = 3 + 4 = 7

Ratio of people who ride the tram to all people in three ways.

= 3 to 7

= 3 : 7

= 3/7

Ratio of all people to people who​ don't ride the tram in three ways.

= 7 to 4

= 7 : 4

= 7/4

Ratio of people who ride the tram to all people in three ways.

= 3 to 7

= 3 : 7

= 3/7
