It will take Layla 6 hours to ride 360 miles

Step-by-step explanation:

Answer:

400 meters

Step-by-step explanation:

First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).

Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.

By the definition of similar polygons, corresponding sides of corresponding triangles are in proportion.

Answer:

x = -7/5

Step-by-step explanation:

3( x - 6 ) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 3 + 10x

-5x - 10x = 3 + 18

-15x = 21

x = [tex]-\frac{7}{5}[/tex]

Answer:

Yes

Step-by-step explanation:

The Triangle Inequality Theorem says the sum of any two side lengths of a triangle has to be greater than the third side.

With the measures of 10, 11, and 2, this follows the theorem.

For example, 10 + 11 is 21, which is greater than 2.

11 + 2 is 13, which is greater than 10.

This works for all the combinations, so 10, 11, and 2 can be the side lengths.

Answer: x=40°

Step-by-step explanation:

The two triangles are congruent (I think it’s called the interior angle proof) so the bottom right angle is also 65°. All angles in a Triangle equal 180°, so 180-(75+65)=40

Answer:10x^2-27x+5. 10x2−27x+5 10 x 2 - 27 x + 5. For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite ...

Step-by-step explanation:

The solution of the equation:

x = -0.28 to the nearest tenth.

x = 4.53 to the nearest tenth.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

A quadratic equation,

4x²-27x-5 = -10x

Simplifying,

4x²-27x-5 + 10x = 0

4x²-17x-5 = 0

So,

x = {-(-17) ± √(289 + 80)}/8

x = (17 ± √369) / 8

When we take - sign,

x = - 0.276

x = -0.28 to the nearest tenth.

When we take + sign,

x = 4.526

x = 4.53 to the nearest tenth.

Therefore, the values are x = -0.28 and x = 4.53.

Answer:

x=8

Step-by-step explanation:

X=8 because 39/3 is 13 and 13- 5 is 8 and 5 and 8 add up to make 13 inside the parenthesis.

x = 8

3(x + 5) / 3 = 39 / 3

x + 5 = 13

x + 5 - 5 = 13 - 5

Step-by-step explanation:

Vertical angles are congruent by the vertical angles theorem.

Hence,

4x-13=3x+19

x=32

Substituting 32 in for x in <A

4(32)-13= 115

Answer:

C

Step-by-step explanation:

The actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes

"percent error = [(estimated value - actual value) / (actual value)] × 100"

For given example,

percent error (e) = 3%

estimated average time spent (x) = 84 minutes

We need to find the actual average time spent (y)

Using the formula of percent error,

⇒ e = [(x - y)/y] × 100

⇒ 3 = (84 - y)/y  × 100

⇒ (84 - y)/y = 3/100

⇒ (84 - y) / y = 0.03

⇒ 84 - y = 0.03y

⇒ 84 = 0.03y + y

⇒ 84 = (1.03)y

⇒ y = 81.5 minutes

Therefore, the actual average time = 81.5 minutes

The correct answer is an option (B) 81.48 minutes
