An equation would be 24-15=9

Step-by-step explanation:

9 seeds didn't sprout

there are only five packets left so 5x24= 120 seeds left to go

Step-by-step explanation:

a) We know that triangle ABD is a right triangle, because of the right angle mark show, and the fact that BD- height, thus perpendicular.

We also know that m<A=30 degrees, due to given diagram.

The sum of all angles in a triangle is 180 degrees. Therefore, m<BDA + m<ABD + m<DAB (Usain Bolt!) = 180 degrees.

m<BAD=30 degrees, m<BDA=90 degrees

Substitute these two in the equation above. You will get that m<ABD=60 degrees.

b) Triangle ABD is a special triangle, with angles of 30,60 and 90.

We know that AD=10[tex]\sqrt{3}[/tex] units.

AD is opposite the 60 degree angle, or <ABD. It is a theorem that the angle opposite to the 60 degree angle is the height (BD) divided by [tex]\sqrt{3}[/tex]. Calculate, and what do you get? BD=10 units!

c) Use the fact that triangle ABC is an isosceles triangle.

d) Use the fact that you know the height, base, and triangle area formula: Base x 1/2 x Height.

I will say no more, but I hope you understand the rest based on your logic.

Answer:

C

Step-by-step explanation:

When an equation has infinitely many solutions, what we have on the right is also what we have on the left side of the equation

Let’s take a look at the third equation;

5.1 + 2y + 1.2 = -2 + 2y + 8.3

5.1 + 1.2 + 2y = 2y + 8.3-2

6.3 + 2y = 2y + 6.3

This equation has infinitely many solutions

Answer:

12.56

Step-by-step explanation:

its really 12.57 but yeah

Step-by-step explanation: To find the circumference of

the circle shown here, start with the formula c = 2πr.

Since the radius is 2 km, we can plug is 2 km for r in the formula.

So we have (2)(π)(2 km) which is equal to 4π km.

Now, remember that π is approximately equal to 22/7 or 3/14.

So we can estimate the value of the

circumference by plugging in 2.14 for π.

So we have (4)(3.14) which is equal to 12.56.

So the circumference is approximately equal to 12.56km.

Answer:

Speed of hike = 1.7 miles per hour

Step-by-step explanation:

Given:

Total distance = 8 miles

Distance already traveled = 4.6 miles

Total time remain to travel  = 2 hour

Find:

Speed of hike

Computation:

Distance remain = Total distance - Distance already traveled

Distance remain = 8 miles - 4.6 miles

Distance remain = 3.4 miles

Speed of hike = Distance remain / Total time remain to travel

Speed of hike = 3.4 / 2

Speed of hike = 1.7 miles per hour

Answer:

thanks i guess i kind of like you don´t get mad

Step-by-step explanation:

Answer: 22 cm.

Step-by-step explanation:

Formula for area of trapezium: [tex]Area = \dfrac12 (\text{Sum of parallel sides})\times \text{(Distance between them)}[/tex]

Given: Area = [tex]550\ cm^2[/tex]

Length of parallel sides : 23 cm and 27 cm

Let h=distance beteen them.

then

[tex]550=\dfrac12 (23+27)(h)\\\\\Rightarrow\ 550=\dfrac12(50)h\\\\\Rightarrow\ 550=25h\\\\\Rightarrow\ h=\dfrac{550}{25}\\\\\Rightarrow\ h= 22[/tex]

Hence, the distance between them  = 22 cm.

Answer:

SAS

Step-by-step explanation:

Answer:

SAS

Step-by-step explanation:

SAS means Side-Angle-Side theorem. Angle A is equal to angle D (sAs), side AB is equal to DE (Sas), and side CA is equal to FD (saS)

angles on a straight like add up to 180

so angle 1 is 180 - 122 = 58

Answer:

58

Step-by-step explanation:

Every straight line equals 180 degrees, so all you have to do is subtract the other side of the line by 180

Answer: Exact solutions are x = 2√2 and x = -2√2

Approximate solutions are x = 2.828 and x = - 2.828

The attachment shows a portion of the graph with this equation. The "zeros" are the solutions.

Step-by-step explanation: To get values for x, we need to isolate x

2x² -6 = 10  Add 6 to both sides and rewrite the equation as

2x² = 16  divide both sides by 2

x² = 8   Factor 8 as 4(2) so you can "pull out" a square.

To solve for x, take the square roots of both sides.

Remember that square roots are positive and negative values.

[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{4(2)}[/tex]

x = ± 2√2

x = 2√2 and  x = -2√2

We can use a calculator to get approximate values of x.

[tex]2\sqrt{2}[/tex] =  ±2.828427125

Round that to x =  2.828 or 2.83 AND x = - 2.828 for approximate values.
