belle put the muffins she baked on six plates, four of which are red and two of which are yellow. the four red plates each have 5 muffins. the two yellow plates each have the same number of muffins write an expersion for the total number of muffins belle baked if each yellow plate has 8 muffins,find how many muffins belle baked in all
Answers
Answer:
36 total muffins
Step-by-step explanation:
5*4=20
8*2=16
20+16=36
Hey there!
To write an expression to represent this:
We know that the four red plates each have 5 muffins, and 4 x 5 = 20.
So we can say 20 + 2y is the expression, because we add 20 to the muffins on the two yellow plates.
The number of muffins on each yellow plate is represented by the variable y.
If each yellow plate has 8 muffins, so y = 8, the expression will look like this:
20 + 2(8)
Multiply 2 x 8.
20 + 16
Add 20 + 16.
36
Belle baked 36 muffins total.

Tony asks 8 people to name their favorite pet. Of the people he asks 2 out of 8 chose rabbit and the fraction of people who choose cat is equal to the fraction of the people choose dogs.
Answers
Question
What fraction choose dogs?
Answer:
[tex]\frac {3}{8}[/tex]
Step-by-step explanation:
When 2 choose rabbits then to get the number that choose other anomals apart from dogs is given by getting the difference between total people and those who choose dogs. This then is expressed as 8-2=6 choose either cat or dogs. These six, half of them choose choose cats and the remaining choose dogs. Therefore 6/2=3
For 3 out of 8, this fraction is equal to

Solve this: 2x+y=-7y Y=x+10
Answers
Answer:
In this equation, when x = -8 , Y = 2
Answer check using either equation =
(1) 2x + y = -7y ===> 2(-8) + 2 = -7(2) ===> -14 = -14
(2) Y= x + 10 ===> 2 = -8 + 10 ===> 2 = 2
Step-by-step explanation:
Assuming that you are looking for "x" and "y", Let
2x + y = -7y ................. (1)
Y= x + 10 ................. (2)
From equation (2), Y = x + 10, therefore substitute for "Y" in equation (1) to get the value of "x"
2x + x + 10 = -7(x + 10)
3x + 10 = -7x - 70
gather like terms on each side.
3x + 7x = -70 - 10
10x = -80
divide through by 10
x = -8
Now substitute for "x" in equation (2)
Y = x + 10
Y = -8 + 10
Y = 2
Let's solve for x.

What is the product of 10 and 9radical 72 in simplest radical form
Answers
Step-by-step explanation:
[tex]10 \times 9 \sqrt{72} \\ = 90 \sqrt{36 \times 2} \\ = 90 \times 6 \sqrt{2} \\ = 540\sqrt{2} [/tex]
Final answer:
To find the product of 10 and 9√72, simplify √72 to 6√2, then multiply the outside coefficients (10 and 9) to get 90, and attach the simplified radical. The final answer is 90√2.
Explanation:
The question asks to find the product of 10 and 9√72 in simplest radical form. First, recognize that the square root of 72 can be simplified by factoring out perfect squares. The square root of 72 is equal to the square root of 36 times 2, which simplifies to 6√2. Now, multiply the outside coefficients (10 and 9) and then multiply the result by the simplified radical. The final simplification is 90√2, which is the product of 10 and 9√72 in simplest radical form.
Amira has 3/4 of a bag of cat food. Her cat eats 1/10 of a bag per week. How many weeks will the food last.
Answers
Answer:15
Step-by-step explanation:
You have to divide the fractions so it 3/4÷1/10 then you can do keep change flip so the new equation is 3/4×10/1 or 3/4×10 then cross simply then get 3/2×5/1 to get 15/2 then use division to get 7 1/2
Amira's cat food will last 7.5 weeks, considering the cat eats 1/10 of a bag per week.
To find out how many weeks the cat food will last, you can divide the amount of food Amira has by the amount her cat eats per week.
First, let's calculate how much her cat eats per week:
1/10 of a bag per week.
Now, let's calculate how many weeks the food will last:
(3/4) / (1/10)
To divide fractions, you can multiply by the reciprocal of the divisor:
(3/4) * (10/1) = (3/4) * 10 = (3 * 10) / 4 = 30/4
Now, let's simplify 30/4:
30 divided by 4 equals 7 with a remainder of 2, so 30/4 = 7 + 2/4
Since 2/4 simplifies to 1/2, we get:
7 + 1/2 = 7.5
So, the cat food will last approximately 7.5 weeks.

Use the distributive property to solve : 20 (30 - 15) =
Answers
Answer:
the distribute property is basically taking the number outside the parenthesis and multiplying with the numbers inside each by each.
Step-by-step explanation:
20(30-15)
20×30= 600, and 20×15=300
finally you just use the new numbers and solve the solution which is 600-300. The answer is 300
Answer: 300
Step-by-step explanation: The distributive property tells us that when there's a number outside a set of parentheses, you can multiply it times each of the terms that are inside the set of parentheses and then add those products together.
So in this problem, we can multiply 20 (30) - 20 (15) which simplifies to 600 - 300 which is 300.

Suppose you have a 42 inch TV that is 57 centimeters tall by 96 CM wide. You want to upgrade to the 60inch version of that TV. The height and width are 42in and 60 in. If you know the width of the 60 inch TV is 137 cm what is the height?
Answers
Answer:
The height is 67 cm
Step-by-step explanation:
Remember that
[tex]1\ in=2.54\ cm[/tex]
we know that
The size of a TV is measured by its diagonal
Convert 60 inches to centimeters
[tex]60\ in=60(2.54)=152.4\ cm[/tex]
Applying the Pythagorean Theorem
[tex]D^2=H^2+W^2[/tex]
where
D is the diagonal
H is the height
W is the width
we have
[tex]D=152.4\ cm\\W=137\ cm[/tex]
substitute
[tex]152.4^2=H^2+137^2[/tex]
solve for H
[tex]H^2=152.4^2-137^2\\H^2=4,456.76\\H=67\ cm[/tex]

The mixed number 4 1/2 is equal to which improper fraction?
A.)8/2
B.)9/2
C.)5/2
D.)4/2
Answers
Answer:
B) 9/2
Step-by-step explanation:
4½ = 4 + ½
= 8/2 + 1/2 = 9/2
Answer: 9/2
Step-by-step explanation: To write a mixed number as an improper fraction, first multiply the denominator times the whole number, then add the numerator.
So here, we multiply the denominator, 2, times the whole number, 4, then we add the numerator, 1. So we have (2 × 4) + 1 of 8 + 1 which is 9.
Finally, we put our new number over our old denominator and we have our answer, 9/2. There is also an image provided showing my work.
So 4 and 1/2 can be rewritten as the improper fraction 9/2.

The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.
Step-by-step explanation:
Step 1:
To determine if the function represents growth or decay, we substitute values to x.
If the values increase with an increase of x, it represents growth.
If the values decrease with an increase of x, it represents decay.
Step 2:
If [tex]x= 10,[/tex] [tex]y = 1,300 (\frac{1}{2})^{\frac{10}{69} } = 1,300 (0.9044) = 1,175.72.[/tex]
If [tex]x=11,[/tex][tex]y = 1,300 (\frac{1}{2})^{\frac{11}{69} } = 1,300 (0.8953) = 1,163.89.[/tex]
So as x increases the value of y decreases, so it represents decay.
Step 3:
The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.
The percentage rate of change [tex]= \frac{y(x=11) - y(x=10)}{y(x=10)}.[/tex]
Substituting the values, we get
The percentage rate of change [tex]=\frac{1,175.72-1,163.89}{1,175.72}(100) = 1.00619\%[/tex].
As the values of y decrease with an increase in x, it is the percent decrease per unit.
Answer:
The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.

Find the volume of a cone that has a radius of 3 inches and a height of 9 inches. Use 3.14 for pi and round your answer to the nearest hundredth.
Answers
Volume of the cone is 100 in³
Step-by-step explanation:
Step 1: Volume of a cone = 1/3 πr²h. Find volume of the cone where r = 3 inches and h = 9 inches.Volume = 1/3 × 3.14 × 3² × 9
= 84.78 in³ ≈ 100 in³ (rounding off to nearest hundredth)
Final answer:
The volume of a cone with a radius of 3 inches and a height of 9 inches is approximately 84.78 cubic inches.
Explanation:
To find the volume of a cone with a radius of 3 inches and a height of 9 inches, you can use the formula for the volume of a cone, which is:
[tex]V = (1/3)\pi r^2h[/tex]
Plugging the given values into the formula gives us:
[tex]V = (1/3) * 3.14 * (3 inches)^2 * 9 inches[/tex]
Now, calculate the square of the radius:
[tex]V = (1/3) * 3.14 * 9 * 9[/tex]
Next, multiply all the numbers together:
[tex]V = 3.14 * 27[/tex]
V = 84.78 cubic inches
Therefore, the volume of the cone is approximately 84.78 cubic inches, rounded to the nearest hundredth.
