Answer:

90 seedlings

Step-by-step explanation:

Total seedlings to plant = 150

Percentage of seedlings planted = 60%

How many seedlings did we plant during that day?

Number of seedlings planted for that day = 60% of 150

= 0.6 × 150

= 90 seedlings

Number of seedlings planted for that day = 90 seedlings

Answer:

v = ~122.23 m/s

Step-by-step explanation:

180(2.8) + 65(3.5) + 200 = 931.5

931.5/(2.8 + 3.5 + 2) = 122.2289 ≈ 122.23 = va

Answer:

first option

Step-by-step explanation:

A perfect square trinomial in the list is

x² + 20x + 100

= (x + 10)(x + 10)

= (x + 10)² ← a perfect square

Answer:

R' = (-2, -3)

Step-by-step explanation:

When a figure undergoes a 180degree rotation, both the (x) and (y) coordinates are multiplied by (-1). The coordinates of the given point are (2, 3). Multiply both of these numbers to fine (R'), that is point (R) after it undergoes its rotation. The coordinates of (R') are (-2, -3).

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

Answer:

Value of x = 2,500

Step-by-step explanation:

Given:

700, 1200, 1600, 2000, x

Mean = 1,600

Find:

Value of x

Computation:

Mean = Sum of all number / Total number

1,600 = [700 + 1200 + 1600 + 2000 + x] / 5

Value of x = 2,500

Answer:

12 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Put 5 in fraction form ( [tex]\frac{5}{1}[/tex] ) and multiply it by [tex]\frac{5}{2}[/tex]

[tex]\frac{5}{1}[/tex]×[tex]\frac{5}{2}[/tex] = [tex]\frac{25}{2}[/tex]   now simplify  to 12 [tex]\frac{1}{2}[/tex]

Answer:

95 cm^2

Step-by-step explanation:

perimeter(p)=39cm

L=3x-1

B=2x+3

Now,

p=2(l+b)

39=2(3x-1+2x+3)

39=6x-2+4x+6

39=10x+4

39-4=10x

x=35/10

x=3.5

Putting the value of x

L=3x-1; =3×3.5-1; =10.5-1; =9.5cm

B =2x+3; =2×3.5+3; =7+3; =10cm

Again,

A= L×B

=9.5×10

=95cm^2

Answer:

B

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

122° is an exterior angle to both triangles , then

∠ 1 + 75° = 122° ( subtract 75° from both sides )

∠ 1 = 47°

and

∠ 2 + 88° = 122° ( subtract 88° from both sides )

∠ 2 = 34°

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Answer:

(-18,9)

Step-by-step explanation (work shown in picture attached):

1) The first step in solving by substitution is to isolate the y-term in one of the equations if it is not already isolated. Isolate y in the first equation by dividing both sides by -2. This leaves us with the equation [tex]y = \frac{-x}{2}[/tex]

2) Now, substitute [tex]\frac{-x}{2}[/tex] for the y in the second equation. Simplify and isolate x. (You can multiply everything by -2 to get rid of the fraction.) This leaves us with x = -18.

3) We've found the x-value of the solution, -18. Now, substitute -18 for x back into one of the original equations (I chose the first one because it was simple) and isolate y. This gives us y = 9. Thus, in point form, the answer is (-18,9).

Answer:

x=9                   x=-1

Step-by-step explanation:

2(x-4)^2=50

Divide each side by 2

2/2(x-4)^2=50/2

(x-4)^2=25

Take the square root of each side

sqrt((x-4)^2)=sqrt(25)

x-4 = ±5

x-4 =5            x-4 = -5

Add 4 to each side

x-4+4=5+4    x-4+4 = -5+4
