Answer:
The correct option is C) x + y + z = 180 degrees
Step-by-step explanation:
Consider the provided information.
It is given that four r, x , y and z.
If x , y and z are the interior angle then,
According to the Angle sum property of triangle: The sum of three interior angles of triangle is 180°.
Therefore, the sum of x , y and z must be equal to 180 degrees.
Hence, the correct option is C) x + y + z = 180 degrees
In the given question it is important to take note of every minute details that are given in the question. using these details the answer to the given question can be easily reached.
Let us assume the common ratio to be x.
Then
x + 9x = 81
10x = 81
x = 81/10
= 8.1
A s we already know that the ratio of chaperones to students is 1:9
Then
The number of chaperones = 1 * 8.1
= 8.1
So 8.1 chaperones were there in total. I hope you have got the answer you were looking for.
Answer:
the answer is C
Step-by-step explanation:
Based on my eyesight, it looks like C intercepts the y-axis at y = 2.
Since the y-intercept is the deciding factor, let's take 2 · 4⁰
Now, 4⁰ = 1, since anything raised to the power of 0 gives 1.
Now, the intercept is at 2 · 1 = 2.
Hence, (C) is the correct graph.
Answer:
<em>y = 4(0.75) or y = 3</em>
Step-by-step explanation:
The question is incomplete. Here is the complete question:
<em>The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.</em>
<em />
<em>Let the amount baking soda required for a whole cake be y.</em>
<em />
<em>If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;</em>
<em />
<em>1/4 sheet of cake = 0.75 teaspoon of soda</em>
<em>1 sheet of cake = y teaspoon of soda</em>
<em />
<em>cross multiply</em>
<em>1/4 * y = 1 * 0.75</em>
<em />
<em>y/4 = 0.75</em>
<em>multiply both sides by 4</em>
<em />
<em>y/4 * 4 = 0.75 * 4</em>
<em />
<em>y = 4(0.75)</em>
<em />
<em>y = 3 teaspoon of baking soda</em>
