Answer:

There are 3 boys for every 4 girls (3:4)

Step-by-step explanation:

3:4 is the simplest form of 24:32 and 6:8.

Therefore, there are 3 boys for every 4 girls.

Answer:

The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.

The odds of the person who lives 20km away from the school being first are way lower than anyone else.

A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

Answer:

24 gallons

Step-by-step explanation:

"Mia has filled 3/4 (three quarters) of the fish tank with water.  How many gallons has she put in the tank to fill it 3/4 full?  Let g be the number of gallons.  Then:

(3/4)(32 gallons) = number of gallons Mia put into the tank:  24 gallons

Answer:

y - 2 = (-1/4)(x - 8)

Step-by-step explanation:

The slope of the given line is 4.  The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.

Use the point-slope formula:

y - k = m(x - h), where (h, k) is the given point.

Then:  y - 2 = (-1/4)(x - 8)

Answer:

2248+2224.91= 4472.91

Step-by-step explanation:

A = $2,248.00

I = A - P = $248.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.1%/100 = 0.031 per year.

Solving our equation:

A = 2000(1 + (0.031 × 4)) = 2248

A = $2,248.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.

A = $2,224.91

A = P + I where

P (principal) = $2,000.00

I (interest) = $224.91

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.7/100

r = 0.027 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.027/1)(1)(4)

A = 2,000.00(1 + 0.027)(4)

A = $2,224.91

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.

Answer:

As 252 has more than two factors, this makes it a composite number. As the sum of digits of 252 is 9, it is divisible by 3 as well as 9. Hence, 3 and 9 are factors of 252.

Answer:

7

8

Step-by-step explanation:

The rate of change per year is the number of books she gets each year.

The problem states "She will buy 7 new puzzle of books each year."

The rate of change per year is 7.

The initial value is the beginning value.

She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.

She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.

43 - 35 = 8

She started with 8 books.

The initial value is 8.

Answer:

The answer is "(4, -5)".

Step-by-step explanation:

Please find the complete question in the attached file.

In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is [tex](x, y) \longrightarrow (y, -x)[/tex]

Putting the value in x = 5 and y = 4 then:

[tex](5, 4) \longrightarrow (4, -5)[/tex]

Answer:

[tex] \huge \orange{m\widehat {FGH} =238\degree} [/tex]

Step-by-step explanation:

[tex] \therefore m\angle FGH + m\angle FAH = 180\degree [/tex]

[tex] \therefore (21x-2)\degree + (38x +5)\degree = 180\degree [/tex]

[tex] \therefore (21x-2+38x +5)\degree = 180\degree [/tex]

[tex] \therefore 59x+3= 180[/tex]

[tex] \therefore 59x= 180-3 [/tex]

[tex] \therefore 59x= 177 [/tex]

[tex] \therefore x= \frac{177}{59}[/tex]

[tex] \therefore x=3[/tex]

Now, by inscribed angle theorem:

[tex] m\angle FAH = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] (38x +5)\degree = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] 2(38\times 3+5)\degree = m\widehat {FGH} [/tex]

[tex] 2(119)\degree = m\widehat {FGH} [/tex]

[tex] 238\degree = m\widehat {FGH} [/tex]

[tex] \huge \purple {\boxed {m\widehat {FGH} =238\degree}} [/tex]

Answer:

22.96 cm

Step-by-step explanation:

Let the point of contact of the tangent with the circle be R.

Let the centre of the circle be O.

We are told that from Point P, the length of the tangent is 24 cm.

Thus, PR = 24 cm

Now, the radius will be perpendicular to the tangent at the point of contact with the circle.

Thus, ORP will form a right angle triangle where ∠R = 90°

Since radius = 7 cm, we can use pythagoras theorem to find OP which is the distance of P from the centre.

Thus;

OP = √(24² - 7²)

OP = √527

OP = 22.96 cm

Answer:

x = -1

y = 1

Step-by-step explanation:

x + 2y = 1     (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1

Answer:

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

2(1 - 2y) + 5y = 3

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

Area: T = 26.143

Perimeter: p = 27

Semiperimeter: s = 13.5

Answer:

YES

Step-by-step explanation:

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

12 + 6   is bigger than 9

12 +9   is bigger than 6

9+6 is bigger than 12

Answer:

95.0

Answer:Michelle

And 50

Step-by-step explanation:

Answer:

x = -4 3/16.

Step-by-step explanation:

First, convert -27/8 to a mixed number. -3 3/8.

So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)

The equation turns into this: 2x = -8 3/8.

Now we can divide by 2 on both sides.

The equation becomes x = -4 3/16.

Hope this helps!

Answer: 121°

Step-by-step explanation:

The measure of angle B will be [tex]121^0[/tex] .

Angle is formed by two rays lie in the plane that contains the rays.

We have,

[tex]m \angle A =(6x-19)^0[/tex]

Now,

Linear pair angles are those angles whose sum is [tex]180^0[/tex] .

i.e.

[tex]m \angle A + m \angle B=180^0[/tex]

So,

[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]

Now,

[tex]17x-41=180[/tex]

[tex]17x=221[/tex]

[tex]x=13[/tex]

So,

[tex]m\angle B=(11x-22)^0[/tex]

Putting value of x;

[tex]m\angle B=(11*13-22)^0[/tex]

[tex]m\angle B=(121)^0[/tex]

So, measure of angle B is [tex]121^0[/tex].

Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .
