Step-by-step explanation:
x / 30 = 150 / 100
100x = 4500
x = 45
Answer:
$45
Step-by-step explanation:
To solve this, cross multiply:
[tex]\frac{x}{30} =\frac{150}{100}[/tex]
100x = 4500
Divide 100 from both sides.
x = 45

A new health drink has 110% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the drink?
Answers
Answer:
110% of 30 is 30*(110/100)=30*1.1=33 mg
Step-by-step explanation:
Answer:
55 mg of the vitamin is in the drink.
Step-by-step explanation:
Create a proportion based on the word problem. In this case, the proportion is: [tex]\frac{110}{100} = \frac{x}{50}[/tex].Find what you must divide by to get from 100 to 50, which is 2.Divide 110 by 2 to solve for x, making the proportion equal.[tex]\frac{110}{100} =\frac{55}{50}[/tex], which means 55 mg of the vitamin is in the drink.

−5.2s − 2.7
−5.2s − 10.8
−2.7s − 2.7
−2.7s − 10.8
first response will get brainiest
Answers
Answer:
-5.2s - 10.8
Step-by-step explanation:
[tex] \rm \implies 4( - 1.3s - 2.7) \\ \\ \rm \implies - 4 (1.3s + 2.7) \\ \\ \rm \implies - (4 \times 1.3s + 4 \times 2.7) \\ \\ \rm \implies - (5.2s + 10.8) \\ \\ \rm \implies - 5.2s - 10.8[/tex]
First you do ( -1.3-2.7) which is -4 and -4 x 4 is -16 and -5.2-10.8 is also -16
-16=-16
Brianna used two congruent parallelograms and a square to create the figure shown.
What is the area of the figure Brianna created in square feet?
Answers
Answer:
33 3/4 ft²
Step-by-step explanation:
The figure comprises of a square with side of 4 1/2 ft and two parallelograms with base of 4 1/2 ft and height of 1 1/2 ft
Total area is:
(4 1/2)² + 2(4 1/2)( 1 1/2) =
(4 1/2)( 4 1/2 + 2(1 1/2)) =
9/2(9/2 + 3) =
9/2(15/2) =

The equation m = 3b represents the time in minutes (m) it takes a chef to cook a certain number of bacon cheeseburgers (b).
Determine the constant of proportionality.
A. 3
B. 6
C. one third
D. 1
Answers
For the given equation:
m = 3b
The constant of proportionality is 3, so the correct option is A.
How to determine the constant of proportionality?
After a small search on the internet, I've found that this question asks for the constant of proportionality.
Remember that a proportional relation is of the form:
y = k*x
Where k is the constant of proportionality, and x and y are the variables.
Here the relation is:
m = 3*b
Where m and b are the variables, then the remaining coefficient is the constant of proportionality, which is 3.
In this way, we can see that the correct option is A.
Answer:
it is 3 since thats the only number there
At a restaurant, hot chocolate can be purchased in two different cup sizes. A 12-ounce cup costs $2.40 and a 16-ounce cup costs $3.20.
Is the linear relationship between cup size and cost also proportional?
Why or why not?
Yes, there is no constant of proportionality.
No, the constant of proportionality is 0.2.
Yes, the constant of proportionality is 0.2.
No, there is no constant of proportionality.
Answers
Answer:
The Answer would be Yes, The constant of proportionality is 0.2
Step-by-step explanation:
When you divide 2.40 by 12 you get 0.2
You get the same thing when you divide 3.20 by 16

In the similar triangles used in indirect measurement with the shadows of a flagpole and a person, which sides of the triangles represent rays of the sun?
Answers
Solving Similar Triangles with Indirect Measurement & Triangles Given. Step 1: Identify the sides and/or angles of the given triangle. Step 2: Calculate the third angle from the equation, ∠A=180∘−(∠B+∠C) ∠ A = 180 ∘ − ( ∠ B + ∠ C ) , where ∠A,∠B,∠C are the three angles of △ABC.
Solution. First, you stand next to the flagpole. Then you measure your height, your shadow's length, and the flagpole's shadow length at the same time. Using similar right triangles for the situation, you can write a proportion and solve for the flagpole's height.
Indirect measurement is a method of using proportions to find an unknown length or distance in similar figures. Two common ways to achieve indirect measurement involve (1) using a mirror on the ground and (2) using shadow lengths and find an object's height.

Find the missing number so that the equation has infinitely many solutions. – 5x–19= (Blank)x–19
Answers
Answer:(number)=-5
Step-by-step explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Answers
Answer:
$220 and $25+15t
Step-by-step explanation:
So first one:
$25 already for each day.
13 tables waited so 13*15=$195
25+195=$220 dollars if waited for 13 tables.
Second:
$25 dollars already.
$15 per table so 15t
So $25+15t
Mackenzie expects to earn $220 in a day, on which she waits on 13 tables. If she waits on t tables, she will earn $15t + $25.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given, Mackenzie will make a guaranteed wage of $25.
Mackenzie noticed that she will get about $15 in tips for each table she waits on.
She waits on 13 tables,
that means, 13 x 15 = $195 of tips.
She earns the total amount in a day
= guaranteed wage + amount from the tips
= $25 + $195
= $220
She waits on t tables,
that means, t x 15 = $15t of tips.
She earns the total amount in a day
= guaranteed wage + amount from the tips
= $25 + $15t
Therefore, she expects to earn $220 in a day, on which she waits on 13 tables. If she waits on t tables, she will earn $15t + $25.
