Answer:

<u>600g</u> of chopped tomatoes

<u>450mL</u> of stock

<u>225mL</u> of red wine

Step-by-step explanation:

You will have to do proportions for all 3 ingredients to make them equal and get the correct amount of each ingredient.

\frac{Amount/you/have}{Amount/you/need}= \frac{x}{Amount/you/need}

The 1st fraction is the beef and the 2nd is the other ingredients.

So, follow the template:

<u />\frac{300g}{400g}= \frac{x}{800g}

Cross multiply:

400x = 240000

240000/400 = <u>600g of chopped tomatoes</u>

\frac{300g}{400g}= \frac{x}{600ml}

Cross multiply:

400x = 180000

180000/400x = <u>450mL of stock</u>

\frac{300g}{400g}= \frac{x}{300ml}

Cross multiply:

400x = 90000

90000/400 = <u>225mL of red wine</u>

The perimeter of a rectangle is 24 m. The length is 30 m less than five times the width. Find the dimensions of the rectangle. L
Len [333]

Answer:

<h2>width = 7 m</h2><h2>length = 5 m</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 24m

The statement

The length is 30 m less than five times the width is written as

l = 5w - 30

Substitute the expression into the above formula and solve for the width

That's

24 = 2( 5w - 30) + 2w

24 = 10w - 60 + 2w

84 = 12w

Divide both sides by 12

w = 7

Substitute this value into l = 5w - 30

That's

l = 5(7) - 30

l = 35 - 30

l = 5

Therefore the dimensions are

width = 7 m

length = 5 m

Hope this helps you

Describe the nature of the roots for this equation.<br> 3x^2+x-5= 0
m_a_m_a [10]

Answer:

<h2>This equation has no natural roots.</h2>

Step-by-step explanation:

3x^2+x-5=0\\\\\text{Use the quadratic formula for}\ ax^2+bx+c=0\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\text{For the given equation:}\\\\a=3,\ b=1,\ c=-5\\\\b^2-4ac=1^2-4(3)(-5)=1+60=61\\\\x=\dfrac{-1\pm\sqrt{61}}{(2)(3)}=\dfrac{-1\pm\sqrt{61}}{6}\notin\mathbb{N}

Identify the equation in slope-intercept form for the line containing the point (-4,1) and (2,3)
oksano4ka [1.4K]

Answer:

The point slope formula is

(y−y1)=m(x−x1)

Where m = the slope calculated as y2−y1x2−x1

(x1,y1)(x2,y2)

(-4 , 1) (-2 , 3)

Solve for the slope

m = 3−1−2−(−3) = 21 = m = 2

(y−3)=2(x−(−2)) Plug in known values.

y−3=2(x+2) Simplify signs

y−3=2x+4 Use Distributive property

y=−2x+4+3 isolate the y variable

answer (y = −5x+7 ) Simplify
