find the equation of a line that is parallel to 4x+y=3 and has a y-intercept of 12

Answer:

25.12 in³

Step-by-step explanation:

v = (1/3)πr²h

Plug in the givens

v = (1/3)(3.14)(4/2)²(6)

v = (1/3)(3.14)(4)(6)

v = 25.12

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

So, we have it that;

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

Answer:

x2 + 4xy - 4y2

Step-by-step explanation:

You have to subtract the values with like terms, so you´d have to take x2 from 2x2. You can´t take away x2 from 6xy because they are different terms, and it wouldn´t be compatible.

Answer:

1.28

Step-by-step explanation:

First, you need to do 82/64, which will give you just x. Then, you need to round to three places. Without rounding it would be 1.28125

So with rounding it would be 1.28. Hope this helps and Happy learning!

x = y = [tex]\sqrt{7\\}[/tex]

Step-by-step explanation:

[tex]\sqrt{7} ^{2} + \sqrt{7} ^{2} = \sqrt{14}^{2}\\7 + 7 = 14[/tex]

Answer:

[tex]3x(x + 5) - 4(x + 5)[/tex]

Step-by-step explanation:

(3x-4)(x+5)

3x(x+5)-4(x+5)

(3x^2+15x)(-4x+20)

3x(x+5)-4(x+5)

Hope this helps you

Answer:

132 cm^2

Step-by-step explanation:

Area of trapezoid = 1/2 ( (7 + 19) * 8) = 26*4 = 104 cm^2

Area of rectangle = 4 x 7 = 28 cm^2

104 cm^2 + 28 cm^2 = 132 cm^2

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

im missing 50 cents somewhere its wrong but close i think sorry

The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.

Total = $37.75

Amount left = $4.00

let

37.75 = p + b + s + 4

37.75 - 4 = p + 1/6s + 3/4p

33.75 = 1/6s + 1 3/4p

33.75 = 1/6(3/4p) + 1 3/4p

33.75 = 3/24p + 7/4p

33.75 = 3+42 / 24p

33.75 = 45/24p

p = 33.75 ÷ 45/24

= 33.75 × 24/45

= 810/45

p = $18

substitute into

s = 3/4p

= 3/4 × 18

= 54/4

s = $13.5

b = 1/6s

b = 1/6 × 13.5

b = 13.5/6

b = $2.25

Step-by-step explanation:

All you have to do is add the exponents

Answer:

5

Step-by-step explanation:

When adding fractions, all you are doing is adding the whole numbers first, 2+2, and then putting that aside. So with 4 on the side, we will then add our fractions. We will line them up and add the numerators and leave the denominator the same. If the numerator is higher than the denominator, we create a whole and subtract the denominator until we are with a smaller numerator. However many times we subtracted this would add a whole number. However, we do not have to do this so we will add 1 and 2 to equal 3. This means we have 3/3 or one whole so we will add 1 to the 4 we had earlier to get 5. Hope this helps :D

Answer:

Since a fraction represents a division, we should do that division to know what the value of a fraction is. The larger numerator, the larger the value of the fraction will be; and the larger denominator, the smaller the fraction will be. ...

Answer:

37 degrees

Step-by-step explanation:

1. m∠CBA = 71+45 = 116 degrees

2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.

3. m∠CBA + m∠CDA = 2*116 = 232.

4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.

5. m∠BAD = m∠BCD = 128/2 = 64 degrees

6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

Answer:

(x + 5)**2 + (y + 2)**2 = 25

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. The graph shows the center at (-5, -2), and the radius of 5. So plugging this in

(x - -5)**2 + (y - - 2)**2 = 5**2

(x + 5)**2 + (y + 2)**2 = 25
