if The ratio of boys to girls in the class was 3 to 2 If there were 12 girls, how many boys were there?

The perimeter of a square is 52 m. What is the area of the square ?

Perimeter of a square = 52 m

4 × side = 52

side = [tex] \frac{52}{4} [/tex]

side = 13

So, area of square = (side)² = (13)² = 169 sq m.

Answer:

A = 169 m²

Step-by-step explanation:

The sides (s) of a square are equal , then

s = perimeter ÷ 4 = 52 ÷ 4 = 13 m

The area (A) of a square is calculated as

A = s² = 13² = 169 m²

Answer: 48 ft

Step-by-step explanation:

Given

Height of street light h=12 ft

length of shadow x=18 ft

Shadow length of building x'=72 ft

suppose the height of the building is y

from the figure, we can write

[tex]\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft[/tex]

Answer:

14.4 years (about 14 years 6 months)

Step-by-step explanation:

Given data

Principal= $3000

Rate= 4.8%

A. Time= 5 years

The expression for compound interest is

A=P(1+r)^t

Substitute

A= 3000(1+0.048)^5

A= 3000(1.048)^5

A=3000*1.264

A=$3792

Hence the balance will be $3792

B. Final Amount A = $6000

The expression to find time is given ast

t= ln(A/P) / r

substitute

t= ln(6000/3000)/0.048

t= ln2/0.048

t= 0.6931/0.048

t=14.43

Hence the time is 14.4 years (about 14 years 6 months)approx

Answer:

375.2887 ft is the answer

Answer:

375.3 ft

Step-by-step explanation:

What we need to do first is divide 175 by the sine of 25°.

175/sin(25°)

175/0.422618

175/1 * 500000/211309

25/1 * 500000/30187

12500000/30187

414.085534 = length of hypotenuse.

Now, find the square root of the difference between c² & a².

b = √414.09² - 175²

b = √171470.528 - 30625

b = √140845.528

b = 375.293922

b ≈ 375.3

The horizontal distance between the technician and the base of the telephone pole is 375.3 ft.

Answer:

Step-by-step explanation:

24n + 32w = (3n + w)

We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.

Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that

24n + 32w = 8(3n + 4w)

Step-by-step explanation:

9x-5(-6x)

9x-5-6x

3x-5

Answer:

15x - 5

Step-by-step explanation:

We have the equation 9x - 5 - (-6x) and are asked to solve it.

We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :

9x - 5 - (-6x)

Two negatives make a positive, therefore :

9x - 5 + 6x

Since 9x and 6x have the same variable ending, we can combine them, do as followed :

9x - 5 + 6x

9x + 6x

15x - 5

Answer:

About 16 days.

Step-by-step explanation:

The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

Step-by-step explanation:

-5x-10>30

(add 10 to both sides)

-5x-10+10>30+10

-5x>40

[tex]\frac{-5x}{-1}[/tex]<[tex]\frac{40}{-1}[/tex]

(dividing through by -1 changes the sign of the inequality from "<" to ">")

5x<-40

(dividing through by 5)

[tex]\frac{5x}{5}[/tex]<[tex]\frac{-40}{5\\}[/tex]

Step-by-step explanation:

10 x 10 = 100 x 10 = 1000 x 10=10000 x 10=100000 x 10= 1,000,000

After multiply the numbers, The correct expression with the same value as ''10 to the power of 6'' is,

⇒ 10⁶

Or, ⇒ 10,00,000

The multiplication of the numbers means to add or sum a number to itself by a particular number of times.

And, Multiplication can be viewed as a process of repeated addition.

We have to given that;

The expression is,

⇒ 10 to the power of 6

Now, We can simplify as;

⇒ 10 to the power of 6

⇒ 10⁶

Expand the powers as;

⇒ 10 x 10 x 10 x 10 x 10 x 10

Multiply all the numbers, we get;

⇒ 1,000 x 1,000

⇒ 10,00,000

Therefore, We get the correct answer is,

The correct expression  with the same value as ''10 to the power of 6'' is,

⇒ 10⁶

Or, ⇒ 10,00,000

Answer:

[tex]y + - 16 = 70 \\ y = 70 + 16 \\ y = 86[/tex]

Hope it helps!!

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4

Answer:

y = 4

Step-by-step explanation:

Please use parentheses for clarity, remembering what big differences they make in expression values.

I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0​" actually means

2/3 - (3/2)y + (1/3)y + 4 = 0​

The LCD here is 6, which is the product of the denominators 2 and 3.

Then your "2/3 - 3/2y + 1/3y + 4 = 0​" becomes:

                     4  - 9y    + 2y + 24 = 0, which simplifies to:

                     28 - 7y = 0.  Solving this, we get y = 4
