Which expression is equivalent to 2 (a + 3) when a = 3? 2 (3) 5 (3) 2 (3) + 3 2 (3) + 6

Answer:

Step-by-step explanation:

Angles: 45°: 45°: 90°

Ratio of sides: 1:1:√2

Given c= 55

a =c/√2

a=55/√2 = 38.9

b=a+2 = 38.9+2 =41.9

The length of the legs of the triangle is 41.9

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.

Angles are: 45°: 45°: 90°

The ratio of sides: 1:1:√2

Given c = 55

a = c/√2

a = 55/√2

a = 38.9

b = a+2

b = 38.9+2

b =41.9

Thus, the length of the legs of the triangle is 41.9

Answer:

8.75° south of west

26.3 mph

Step-by-step explanation:

Let's say that east is +x and north is +y.

The sailor's horizontal velocity is -26 mph.  The vertical velocity is -4 mph.  So the velocity vector is in the 3rd quadrant.  The direction is:

θ = tan⁻¹(-4 / -26)

θ = 188.75°, or 8.75° south of west.

The magnitude of the speed is:

v = √((-4)² + (-26)²)

v = 26.3 mph

Answer:

f(x) has a larger growth rate

f(x) is always greater than g(x)

Step-by-step explanation:

f(x) = 2/5 x

g(x) = -2x

the slope of f(x) when graphed is 2/5 x, which is a positive value making it a larger growth rate than g(x) and it also will always be greater since the value of f(x) is positive

therefore the correct true statements are:

f(x) has a larger growth rate, and f(x) is always greater than g(x)

options 1 and 3

Step-by-step explanation:

option 1 is correct because f (x) is positive hence making it greater than g(x) which is negative.

Step-by-step explanation:

To find the perimeter of a rectangle

P = 2 (l+w)

4533 = 2 ( x+3  + 2x-6)

Combine like terms

4533 = 2 ( 3x -3)

Distribute

4533 = 6x -6

Add 6 to each side

4533+6 = 6x

4539 = 6x

Divide by 6

Area = l x w = 40 x 20

= 800 sq ft.

Answer:

Step-by-step explanation:

This is a linear pair, whose sum always equals 180 degrees,

hence, we can set up the equation:

2z+140=180

2z=180-140

2z=40

z=40/2

z=20

Thus, the answer is 20 degrees

Answer:

z = 20°

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

2z+ 140 = 180

Subtract 140 from each side

2z+140-140 = 180-140

2z = 40

Divide by 2

2z/2 = 40/2

z = 20

Answer:525 boys

Step-by-step explanation:

Multiply 1250 times .58 and then subtract that answer from 1250....

1250x.58=725

1250-725=525

Answer:

There are 525 boys in that school.

Step-by-step explanation:

Since the number of students in that school are 1250 and 58% of them are female, therefore the percentage of the male is

⇒100% - 58% = 42%

To find how many boys are in that school, you multiply 1250 by 42%.

i.e. [tex]\frac{42}{100} * 1250[/tex]

= [tex]\frac{42}{10} * 125[/tex]

= 4.2 × 125

= 525

∴ There are 525 boys in that school.

OR

You can find the number of boys there by subtract the product of 58% and 1250 by 1250.

i.e. Number of girls= [tex]\frac{58}{100} * 1250[/tex]

                                     = [tex]\frac{58}{10} * 125[/tex]

                                     = 5.8 × 125

                                     = 725

∴ The boys in that school are:

= 1250 - 725

= 525

∴ There are 525 boys in that school.
