The 3 question please with explained

victus00 [196]

Answer:

Step-by-step explanation:

Rectangle:

length = l = 12 cm

Width = w = 0.8 cm

Use Pythagorean theorem to find the diagonal

Diagonal² = l² + w²

= 12² + 0.8²

= 144 + 0.64

= 144.64

Diagonal = √144.64 = 12.03 cm

Diagonal of square = diagonal of rectangle

= 12.03 cm

To find the side of square again use Pythagorean theorem,

side² + side² = 12.03²

2 sides² = 144.64

side² = 144.64/2

side² = 72.32

side = √72.32

Side = 8.50 cm

A new soup recipe contains 33 percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligra

masya89 [10]

Answer:

The expressions that could represent the amount of sodium per serving, in milligrams, in the new soup recipe is a) 0.67x

Step-by-step explanation:

Given:

A new soup recipe contains 33 percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.

Now, to find the expression that could represent the amount of sodium per serving, in milligrams, in the new soup recipe.

The old soup recipe contained sodium per serving = $x\ milligrams.$

As given, the new soup recipe contains 33 percent less sodium per serving than the old soup recipe.

So, to get the amount of new soup recipe sodium per serving we write an equation:

$x-33\%\ of\ x$

= $x-\frac{33}{100} \times x$

= $x-\frac{33x}{100}$

= $x-0.33x$

= $0.67x.$

Thus, the expression $0.67x$ milligrams represent the amount of sodium per serving in new soup recipe.

Therefore, the expressions that could represent the amount of sodium per serving, in milligrams, in the new soup recipe is a) $0.67x.$

What is the equation, in slope-intercept form, of the line that passes through the points (−24, 5) and (16, −20)?

ser-zykov [4K]

Answer:

C (Y = -5/8x - 10)

Step-by-step explanation:

first find the slope (y₂ - y₁) ÷ (x₂ - x₁)

(5 - (-20)) ÷ (-24 - 16)

-5/8 = slope (m)

now that we know the slope is -5/8 we can rule out A and B

now to find the y intercept just substitute a point in for x and y

5 = (-5/8)(-24) + b

multiply

5 = 15 + b

subtract 15 from both sides tp isolate b

-10 = b
