Find the slope of the line.

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.

Complete Question

The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes, Kate ran a mile in 10.87 minutes, and Rubin ran a mile in 8.46 minutes. How many more minutes did Emmett run than Robin?

a. 1.37 minutes

b. 1.27 minutes

c. 2.27 minutes

d. 1.27 seconds

Answer:

1.27 minutes

Step-by-step explanation:

Emmett ran a mile in 9.73 minutes

Kate ran a mile in 10.87 minutes

Rubin ran a mile in 8.46 minutes.

How many more minutes did Emmett run than Robin?

This is calculated as:

Number of minutes Emmett ran - Number of minutes Rubin ran

= 9.73 minute - 8.46 minutes

= 1.27 minutes

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: 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.

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

5.2+4.8=10

yes, because the two shorter sides add up to a equal or greater length than the longest side

i think this is how it works im sorry if im wrongg

dude they answer choices that you wrote and the answer choices in the picture aren't the same

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:

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: y=2x

Step-by-step explanation: I'm 99% sure I'm right.

Answer:

The value of x is 5 and the value of y is -2

Step-by-step explanation:

If the question is to determine the values of x and y, this can be related to the elimination method for solving simultaneous equations.

From the third linear equation, -13x = -65, the value of x can be determined.

-13x = -65

Divide both sides by -13

Then,

-13x/-13 = -65/-13

x = 5

∴ The value of x is 5.

To determine the value of y, the value of x is substituted into any of the first two equations. Say -10x + 5y = -60

-10x + 5y = -60

Substitute x = 5 into the equation

-10(5) + 5y = -60

-50 + 5y = -60

Add 50 to both sides

-50 +50 + 5y = -60 +50

Then,

5y = -10

Divide both sides by 5

5y/5 = -10/5

y = -2

∴ x = 5, y =-2

Hence, the value of x is 5 and the value of y is -2.
