Answer:

140°

Step-by-step explanation:

$\because m\widehat{BG} = 360\degree - m\widehat{GCB} \\\therefore m\widehat{BG} = 360\degree - 300\degree \\\therefore m\widehat{BG} = 60\degree \\\because m\widehat{BGD} = m\widehat{BG} +m\widehat{GD}\\\therefore m\widehat{BGD} = 80\degree+60\degree\\\therefore m\widehat{BGD} = 140\degree\\\because m\angle BAD = m\widehat{BGD} \\\huge\purple {\boxed {\therefore m\angle BAD =140\degree}}$

Val returned a bicycle while she was on vacation. She paid a flat rental fee of $55.00 plus $8.50 each day. The total cost was $

never [62]

Number of days Val rented the bicycle is 8

<h3><u>Solution:</u></h3>

Given that val paid a flat rental fee of $55.00 plus $8.50 each day

The total cost was $123

To find: number of days she rented the bicycle

Let "a" be the number of days she rented the bicycle

Rental fee = $55.00

Fee for one day = $ 8.50

So total cost is equal to rental fee and fee for "a" days

Total cost = rental fee + (number of days she rented the bicycle x Fee for one day)

$123 = 55.00 + (a \times 8.50)$

$123 = 55 + 8.50a$

123 - 55 = 8.50a

8.50a = 68

$a = \frac{68}{8.50} = 8$

Thus number of days she rented the bicycle is 8

Write the equation 8y = 1/12 x – 0.8 in standard form. Identify A, B, and C.

PolarNik [594]

Answer:

The equation is 10x - 960y = 96

A = 10 , B = -960 , C = 96

Step-by-step explanation:

* Lets explain the standard form of the linear equation

- The standard form of the linear equation is :

AX + BY = C , where A , B , C are constant

- A is a positive integer, and B, and C are integers

- The slope of the line is -A/B

- The y-intercept is C/A

- Lets solve the problem

∵ The equation of the line is 8y = 1/12 x - 0.8

- At first multiply the equation by 12 to make the coefficient of x integer

∴ (8 × 12) y = (1/12 × 12) x - (0.8 × 12)

∴ 96y = x - 9.6

- Multiply the two sides of the equation by 10 to make 9.6 integer

∴ (96 × 10) y = (1 × 10) x - (9.6 × 10)

∴ 960y = 10x - 96

- Add the two sides by 96

∴ 960y + 96 = 10x

- Subtract 960y from both sides

∴ 96 = 10x - 960y

∴ The standard form of the equation is 10x - 960y = 96, where

A = 10 , B = -960 , C = 96

Jamal is running 42 kilometers. The amount of time t it takes Jamal to run varies inversely with the rate, r, at which he runs,

leva [86]

Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r

2476 adults watch a cricket match. The ratio men : women is 3 : 1 How many more men than women watch the match?

poizon [28]

he ratio of 3:1 involves 4 units. 3 men +1 woman.

Find how many people each unit represents:

4units 2476 people

Therefore each unit represents 2476/4 = 619 people per unit

Now, take the ratio, and multiply up:

3:1 => 3619:1619 => 1857:619 You check this is right by adding the two fractions:

1857 men + 619 women = 2476 people therefore, we are correct

The number of men more than women = Number of men - Number of women

= 1857-619 = 1238 and that is your answer
