Answer:

When reading decimal numbers, read the whole number part as normal, use "and" to represent the decimal point and continue reading the number as normal, but end with the last place value.

For example: how do you read 36.57 --> thirty-six and fifty-sevens hundredths

When writing decimals it is like reading them. You write the whole part as normal, and write a decimal to represent where you would say "and". Continue writing the number.

For example: Write eighty-five and sixty-four hundredths --> 85.64

What is the slope of the line whose equation is -48 = 2x - 8y? Enter your answer in the box.

aleksandr82 [10.1K]

Answer:

The slope is $\frac{2}{8}$

Step-by-step explanation:

Take the general equation of a straight line $y = mx+c$

Here $m$ is the slope of the line.

So let's get the equation of the line in the question in the same form.

$-48 = 2x-8y$

Add $8y$ to both sides: $8y - 48 = 2x$

Add $48$ to both sides: $8y = 2x + 48$

Divide by $8$ to get it into the general equation: $y = \frac{2}{8} x + 6$

Now compare it to the general equation to find the value of $m$ . The value of $m$ is the coefficient of $x$ which we can see is $\frac{2}{8}$

The ratio of boys to girls in a group is 4:1. If there are 33 more boys than girls, work out how many people there are in total.

MissTica

Total number of people is 55

Step-by-step explanation:

Step 1:

Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x

⇒ 4x + x = x + 33 + x

⇒ 5x = 33 + 2x

⇒ 3x = 33

⇒ x = 11

Step 2:

Find total number of people.

33 + 2x = 33 + 22 = 55

Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe call

MrRa [10]

Answer:

2 cartons

Step-by-step explanation:

Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.

Next, we need to find what we need to know, how many fluid ounces are in a cup? There are 8 fluid ounces in 1 cup!

Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).

8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces

So! Martina needs 64 fluid ounces of broth to be able to create her recipe!

But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!

64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons

Melina needs to buy 2 cartons of broth to be able to complete her recipe.

Hope this Helps! :)
