klemol [59]

Answer:

Step-by-step explanation:

It's a matter of proportions.

Let's call them A and B. Now, let's make an equation.

$\frac{535}{a} = \frac{320}{64} = 5$

Now that we know that...

$A = \frac{535}{5} = 107 in = 8 ft 11 in$

When Han makes chocolate milk, he mixes 2 cups of milk with 3 tablespoons of chocolate syrup. Here is a table that shows how to

Korvikt [17]

Answer:

Part a) The table shows a proportional relationship between tablespoons of chocolate syrup and cups of milk

Part b) The scale factor is 1.5

Part c) The constant of proportionally for this relationship is 1.5

Part d) The units for the constant of proportionality are tablespoons of chocolate syrup per cups of milk

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 $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line

Let

x ----> the quantity of cups of milk

y ----> the quantity of tablespoons of chocolate syrup

k ---> the constant of proportionality

For y=3, x=2 -----> $k=\frac{y}{x}=\frac{3}{2}=1.5$

For y=12, x=8 -----> $k=\frac{y}{x}=\frac{12}{8}=1.5$

For y=3/2, x=1 -----> $k=\frac{y}{x}=\frac{(3/2)}{1}=1.5$

For y=15, x=10 -----> $k=\frac{y}{x}=\frac{15}{10}=1.5$

therefore

The table shows a proportional relationship between tablespoons of chocolate syrup and cups of milk

The linear equation is

$y=1.5x$

That means----> The the quantity of tablespoons of chocolate syrup is 1.5 times the quantity of cups of milk

The scale factor is equal to the ratio between tablespoons of chocolate syrup and cups of milk. Is equal to the constant of proportionality k

The scale factor is 1.5

The constant of proportionality is 1.5

The units for the constant of proportionality are tablespoons of chocolate syrup per cups of milk

$\frac{tablespoons\ of\ chocolate\ syrup}{cups\ of\ milk}$

Which of the following best explains how a single nucleotide substitution can cause hemoglobin molecules to chain together ins

horsena [70]

The correct option is this: THE MUTATION CAUSES THE WRONG AMINO ACID TO BE INCORPORATED INTO THE PROTEIN PRODUCT, WHICH RESULTS IN IMPROPER FOLDING.
There are different type of mutation, one of them is substitution mutation. Substitution mutation occurs when one nucleotide is exchanged for another during the process of nucleotide incorporation. Such a change will result in change in the function of the protein that is been formed.
