So far, he has ridden 70% of the bike course.

Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".

The formula to get the percentage is:

Percentage = (Value / Total Value) × 100

If the total value of the bike course is 40 miles and the value which the percentage we are looking for is 28 miles, evaluating the equation:

Percentage = (Value / Total Value) × 100

Percentage = (28 / 40) × 100

Percentage = (0.7) × 100

Percentage = 70

Therefore, he has ridden 70% of the bike course so far.

If angle A and angle B are vertical angles. If m angle A=(2x+20)^ and m angle B=(3x+1)^ then x has a value of 19.

What is the Vertical Angles Theorem?

The Vertical Angles Theorem states that if two lines intersect, then the vertical angles formed by the intersecting lines are congruent.

Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. Vertical angles are always congruent angles,

By the Vertical Angles Theorem, we know that angle A is congruent to angle B.

Therefore, we can set their angle measures equal to each other and solve for x:

2x + 20 = 3x + 1

Subtract 2x from both sides:

20 = x + 1

Subtract 1 from both sides:

19 = x

Hence, x has a value of 19.

The standard deviation of the distribution = 1.5°F

Given that the distribution of daily high temperature is approximately normal.

Population mean, [tex]\mu[/tex] = 86°F

Also approximately 95% of all daily high temperatures are between 83°F and 89°F.

So here [tex]X_1[/tex] = 83°F and [tex]X_2[/tex] = 89°F

We have the z - statistic ,

             [tex]z=\frac{x-\mu}{\sigma}[/tex]

where [tex]\sigma[/tex] is the Standard deviation.

For 95% probability, the z-value for normal distribution is 1.96.

As we consider the positive z-value, take X =  [tex]X_2[/tex] =  89°F

So,   [tex]z=\frac{x-\mu}{\sigma}[/tex]

⇒  [tex]\sigma = \frac{x-\mu}{z} = \frac{89-86}{1.96} =1.53[/tex] ≈ 1.5°F

So the standard deviation of the distribution = 1.5°F

[tex] {x}^{2} + 4x - 7 = 0 \\ → {x}^{2} + 4x = 7[/tex]

Add the square of the half of the coefficient of the unknown(x) to both sides of the equation.

[tex] {x}^{2} + 4x + ( \frac{4}{2} {)}^{2} = 7 + ( \frac{4}{2} {)}^{2}[/tex]

[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + (2 {)}^{2} [/tex]

[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + 4[/tex]

Bring out x and 2 and square them as shown below:

[tex](x + 2 {)}^{2} = 11[/tex]

Now, square root both sides of the equation to find the value of x as shown below:

[tex] \sqrt{(x + 2 {)}^{2} } = \sqrt{11} [/tex]

Add a + or - sign since it is a quadratic equation

[tex]x + 2 = \binom{ + }{ - } \sqrt{11} [/tex]

[tex]x + 2 = \binom{ + }{ - } 3.3166[/tex]

[tex]x = - 2 + 3.166 [/tex] or

[tex]x = - 2 - 3.166[/tex]

Therefore:

[tex]x = 1.17[/tex] or

[tex]x = - 5.17[/tex]

a = h/b

x b, both sides

ab = h

÷a

b = h/a

B = h/a

Hope this helps!

Answer: b = h/a

Step-by-step explanation: What you need to do is to get b by itself and to do that you have to move b to the other side because it's being divided by b. To do that you multiply by b on both sides.

1) ab = h

Now, isolate b by dividing a into both sides.

2) b = h/a

Now, you have b alone you know what b is equal to.

Answer:  29

Step-by-step explanation:

The reason why it's a positive instead of a negative is because when you have an even number of positives in an equation the answer will always be positive and vice versa.

Scale being used = 1 : 300

It is given that the model measured the height as 2.5cm.

The height of the hall = 7.5 m = 750 cm

By using the formula

Scale to be used = size down/ Actual size

                            = 2.5/ 750

                            = 1/300

Answer:

2x + 2 + h.

Step-by-step explanation:

F(x+h) is f(x) where x+h replaces x:-

f(x + h) = (x + h)^2 + 2(x + h) - 3

[f(x+h) - f(x)] / h

= (x + h)^2 + 2(x + h) - 3 - (x^2 + 2x - 3)  /  h

= [x^2 + 2hx + h^2 + 2x + 2h - 3 - x^2 - 2x + 3] / h

= (2hx + h^2 + 2h) / h

= 2x + 2 + h

The limit of [f(x+h) - f(x)] / h as h ----> 0 is 2x + 2.

We refer to 2x + 2 as the derivative of x^2 + 2x - 3.

After the translation the coordinates of L' are (-3, 0) for the new triangle of U’M’L’.

The coordinates of triangle are-

U (-3, -4), M(-1, -1) , and L(-2, -5).

The triangle is translated 5 units up and 1 unit left to its original place.

Thus, for the 5 units up translation 5 units will get added to the y-coordinates.

New y-coordinate of L' is -5 + 5 = 0.

For 1 unit left , 1 units will get reduced from the original x-coordinate.

New x-coordinate = -2 - 1 = -3

Thus, the new coordinates L' becomes (-3, 0).

The required equation would be t  = (nRT + 5ab)/M which is the result of the equation for t.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given as

Mt - 5ab = nRT

We have to determine the result of solving this equation for t

⇒ Mt - 5ab = nRT

⇒ Mt  = nRT + 5ab

⇒ t  = (nRT + 5ab)/M

Therefore, the required equation would be t  = (nRT + 5ab)/M which is the result of the equation for t.
