Answer:

40% are boys

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 = 5 parts

Divide number in class by 5 to find value of one part of ratio

30 ÷ 5 = 6 ← value of 1 part of the ratio, then

2 parts = 2 × 6 = 12 ← number of boys in class

percentage = [tex]\frac{boys}{total}[/tex] × 100%

                   = [tex]\frac{12}{30}[/tex] × 100%

                  = 0.4 × 100% = 40%

Answer:

40%   simplify the fraction then divide (boys/total)  then multiply by 100

Step-by-step explanation:                                                                                   2+3 = 5 is the distributer then :                                                                             30/5 = 6  then if 2 are boys  2 x 6 = 12 is the amount of boys                       12/30 = 2/5  simplified and then x 100 to fraction's to find percentage           2/5  x 100 =  40%                                                                                                            

Answer:

If x=-1 then y= -3

If x=0 then y=1

If x=1 then y= 4

If x=2 then y= 7

Step-by-step explanation:

Basically, let's represent the amount of money earned in

July with x

and

August with x+90

x+(x+90)=350

2x+90=350

2x=350-90

2x=260

x=260÷2

x=130

So, Wanda earned $130 babysitting in July and in July, 130+90=$220.

Hope this helps!

Answer:

After , the sequence repeats itself

Divide 37/4 = 9 R 1. Now use the remainder and find which one of the values of i it matches.

so

Step-by-step explanation:

The expressions are simplified as;

i. t = ∛i

ii. t = 1

From the information given, we have that;

Simplifying  [tex]t^3^7[/tex] = √i

When [tex]t^3^7[/tex]equals i (the imaginary unit), we can solve for "t" by taking the 37th root of both sides:

[tex]t^3^7 = i[/tex]

[tex]t = \sqrt[3]{i^3^7}[/tex]

[tex]t = i^(^3^7^/^3^)[/tex]

Since i^4 = 1 (i raised to the power of 4 is 1), we can simplify the exponent:

[tex]t = i^(^1^2 ^+ ^1^/^3^)[/tex]

[tex]t = i^1^2 ^* i^(^1^/^3^)[/tex]

Now, since[tex]i^1^2[/tex] = 1 and [tex]i^(^1^/^3^)[/tex] represents the cube root of i, we have:

t = 1 * ∛i

t = ∛i

Simplifying [tex]t^8^2[/tex] = √ –1:

Take the 82nd root of -1

[tex]t^8^2 = -1[/tex]

t = [tex]\sqrt{(-1)^8^2}[/tex]

t = √1

t = 1

Answer:

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

You will pay $3.78 in tax. And you would pay a total of $66.78

Step-by-step explanation:

Answer: $3.78 or $66.78 if you are looking for the total amount including tax.

Step-by-step explanation:

6% can be represented by 0.06 so multiply that by 63

63*0.06=3.78

You will pay $3.78 in taxes

The total is 66.78 but I think you are asking for the tax.

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180 degrees

so 40 + (16x + 2) + ∠C = 180

The straight angle is 180°

so ∠C = 180 - (23x + 7)  

∠C = 180 - 23x -7

∠C = 173 - 23x

and then 40 + (16x + 2) +(173 - 23x) = 180

40 + 16x + 2 + 173 - 23x = 180

215 - 7x = 180

-7x = 180 - 215

-7x = -35

x = 5

Answer:

Surveying To approximate the length of a marsh, a surveyor walks 250 meters from point  to point  , then turns  and walks 220 meters to point  (see figure). Approximate the length  of the marsh.

hope it helped

Step-by-step explanation:

The approximate length of the lake is 625 yards.

Given that, a surveyor starts at one end of the lake and walks 245 yards.

A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.

He then turns 110 and walks 270 yards until he arrives at the other end of the lake.

Total length of the lake is

245+110+270 =625 yards

Therefore, the approximate length of the lake is 625 yards.
