Find each numbered angle measure:

Answer:

The correct option is; A. [tex]y = \dfrac{7}{4} x + 7[/tex]

Step-by-step explanation:

The given equation is 4·y - 7·x = 8

The coordinates of the point the line passes = (-4, 0)

By dividing the given equation by 4, we have;

4·y/4 - 7/4·x = 8/4

Which gives;

y  - 7/4·x = 2

y   = 7/4·x + 2

Which is the equation of a straight line in slope and intercept form, y = m·x + c, with the slope, m = 7/4, and the y-intercept = 2

Given that the required line is parallel to the graph of the equation, 4·y - 7·x = 8, the slopes of both equations are equal we have;

Slope of required line = 7/4, point on the line = (-4, 0), which gives the following point and slope form equation of a straight line;

y - 0 = 7/4 × (x - (-4))

y = 7/4·x + 7/4 × 4 = 7/4·x + 7

The equation of the line is therefore;

y = 7/4·x + 7

Answer:

142.1π in³

Step-by-step explanation:

Given that:

The radius (r) =  7 in

The slant height (y) = 25 in

Then the height (x) can be determined by using the Pythagoras rule:

y² = x² + r²

25² = x² + 7²

125 = x² + 49

125 - 49 = x²

x² = 76

x = √76

x = 8.7

The formula for the volume of a cone is;

= 1/3 πr²h

where;

height(h) is calculated as "x" from above = 8.7

Then;

= 1/3 × π × (7 in)² × 8.7 in

= 142.1π in³

Answer:

4c² + 11cd + 5d

Step-by-step explanation:

To add monomials, you have to look at the variables that are accompanied by their coefficients. In the given problem, (–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd), you can combine both cd ut nt cd and c² and cd and d and d and c² because they have different variables.

(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)  

(-4c² + 8c²) + (7cd + 4cd) + (8d - 3d)

4c² + 11cd + 5d

Answer:

Cost of shoes = $37.4925

Cost of jacket = $92.4533

Tax = $9.81

Total paid = $144.2458

Step-by-step explanation:

Normal price of shoes = $49.99

Discount = 25%

Discounted price:

[tex]\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925[/tex]

Normal price of jacket = $137.99

Discount = 33%

Discounted price:

[tex]\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533[/tex]

Price of pack of cookies = $4.49

No discount on cookies as per question statement.

Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358

Sales Tax = 7.3% of total amount without tax = 7.3% [tex]\times[/tex] $134.4358 = $9.81

Total paid = $134.4358 + $9.81 = $144.2458

Answer: y = mx + b

4x - 6y = 10

-6y = -4x + 10

y = (-4/-6)x + 10/-6

y = (2/3)x - 5/3

m = 2/3

Answer:

880

Step-by-step explanation: Every three days the balance increases by 120 so you would divide 120 by 3 to get 40. This would mean that the balance increases by 40 everyday so after seven days the balance would be 880

Answer:

x is -9

CB is 10

Step-by-step explanation:

In order to solve this question we need to figure out what x is first

First we do

2(x+19)=x+29

Then we get 2x+28=x+29

subtract and divide to get

x=-9

Plug in the x to get CB

-9+19=10

Answer:

The card had 41.60 originally

Answer:

a = 6

b = 3

c = 2

Step-by-step explanation:

Since n(P) = a+b = 9

and n(Q) = b+c = 5

and b is given to be 3

a and b follow easily.

a is 9-b = 9-3 = 6

c is 5-b = 5-3 = 2

Answer:

3.5 Liters

Step-by-step explanation:

Since 500 ml is equal to 0.5 liters and there are 7 days in a single week you just need to multiple the number of liters (0.5) by the 7 days to get a total of 3.5 liters

Answer:

8

Step-by-step explanation:

When doing these types of problems, we convert the percent to a decimal. In this case,

40%=0.4

0.4*20=8

Answer:

200%

Step-by-step explanation:

20 = 100%       (in this case)

40 = 200%        (because you multiply both sides to get 40)

Therefore, 40 is 200% of 20.

Answer:

y - (1.01nd + 7)

Step-by-step explanation:

Quinton bought n number of shares for d dollars and paid a 1% commission. It means he bought [tex]\dfrac{1}{100}nd=0.01nd[/tex]

He sold the stock for y dollars and paid a flat fee of  $7. It means he sold y-7.

We need to find Quinton's net proceeds algebraically. It will be given as :

[tex]y-7-0.01nd\\\\=y-(0.01nd+7)[/tex]

Hence, the correct option is (d) i.e. y - (1.01nd + 7)

Answer:

slope- -1/3

a point: (0, [tex]\frac{31}{3}[/tex])

Step-by-step explanation:

y-9= -1/3(x-4)

y-9= -1/3x+4/3

y= -1/3x+31/3

to find a point:

y= -1/3(0)+31/3

y=31/3

(this happens when x= 0, so the point is (0,31/3)

m=-1/3

Point: (4,9)

Step-by-step explanation:

i just took the question and got it right on ed2020

We have to make sure the denominators are equal.

10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10

Now the equation is 4/10 + 6/10

Since our denominators match, we can add the numerators.

4 + 6 = 10

That gives us the sum, which is 10/10 aka 1 whole

your welcome :) (btw can u please give brainly?)

Answer:

2/5 + 6/10 = 1

Step-by-step explanation:

first let’s change 2/5 so it has the same denominator as 6/10.

2/5 * 2/2 = 4/10

now add

4/10 + 6/10 = 1
