Answer:

Part a), Part b) and Part c) see the explanation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the amount of vinegar in tablespoons

y ----> the amount of oil in tablespoons

In this problem

The relationship between the variables x and y represent a proportional variation

The constant of proportionality k is equal to the ratio of the recipe

substitute

The linear equation is equal to

Explain the meaning of the point (1.1.5)

we have

x=1, y=1.5

In the context of the situation

This means ----->The amount of oil needed is 1 (tablespoon) if the amount of vinegar used is 1.5 (tablespoons) to make the salad dressing according to this recipe.

see the attached figure to better understand the problem

Write the equation of a line that is perpendicular to y=-2x/7+9 and that passes through the point (4,−6)

Shtirlitz [24]

Answer:

y = (7/2)x -20

Step-by-step explanation:

The given line is in slope-intercept form, so you can read its slope from the equation.

y = mx + b . . . . . m is the slope; b is the y-intercept

y = -(2/7)x + 9 . . . . . . has slope -2/7

The perpendicular line will have a slope that is the negative reciprocal of this, so will be ...

m = -1/(-2/7) = 7/2

We can use this and the given point to write the equation in point-slope form.

y = m(x -h) +k . . . . . . line with slope m through point (h, k)

We have m = 7/2, (h, k) = (4, -6) so the equation is ...

y = (7/2)(x -4) -6

y = (7/2)x -20

Scott bought a 5lb bag of cookies at the bakery. He ate 2/5 of the bag and his sister ate 2/9 of the bag. What fraction of the b

satela [25.4K]

Answer: Fraction they both eat = $\dfrac{28}{45}$ .

Fraction of bag remains = $\dfrac{17}{45}$

Step-by-step explanation:

Given: Part of cookies eaten by Scott = $\dfrac25$

Part of cookies eaten by sister = $\dfrac{2}{9}$

Fraction they both eat = $\dfrac25+\dfrac29=\dfrac{9\times2+5\times2}{5\times9}$

$=\dfrac{18+10}{45}\\\\=\dfrac{28}{45}$

Fraction of the bag remain = $1-\dfrac{28}{45}=\dfrac{45-28}{45}=\dfrac{17}{45}$

[Taking fraction of whole bag =1]

Hence, Fraction they both eat = $\dfrac{28}{45}$ .

Fraction of bag remains = $\dfrac{17}{45}$

Rewrite the rational exponent as a radical by extending the properties of integer exponents. 2 7/8 divided by 2 1/4

VladimirAG [237]

We know the rule of change: a b/c= (ac+b):c
So we have 2 7/8= (2x8+7):8= 23/8
and the second: 2 1/4 = (2x4+1):4= 9/4
We do the division: 23/8: 9/4= 23/8 x 4/9= (23x4):(8x9)= 23/18= 1 5/18
