A pet store has two types of betta fish ref betta fish and blue betta fish a customer notices that 7 out of 12 betta fish in the store are red what is the ratio of blue betta fish to red betta fish?
Answer:
5:7
Step-by-step explanation:
A pet store has two types of betta fish which is red and blue
She noticed that 7 out of the 12 beta fishes are red
This means that there are 7 red beta fishes and 5 blue betta fishes
Therefore the ratio of blue betta fish to red betta fish is
= 5:7
The volume of a box is 120 cubic feet, the width and length are equal to x, the height is y. Find the dimensions that use the least amount of material. V=x^2 * y
Answer:
The answer is below
Step-by-step explanation:
The volume of box = width * length * height
120 = x * x * y
120 = x²y
y=120/x²
The surface area (SA) = sum of the area of all faces side
SA = x² + x² + xy + xy + xy + xy
SA = 2x² + 4xy
substitute y =120/x²
SA = 2x² + 4x(120/x²)
SA = 2x² + 480/x
Taking the derivative:
SA' = 4x - 480/x²
making SA' = 0:
0 = 4x - 480/x²
480/x² = 4x
4x³ = 480
x³ = 120
x = 4.93 feet
y = 120 / x² = 120 / 4.93² = 4.93
Hence the width, length and height is 4.93 feet.

You have $18 to buy peppers. Peppers cost $1.50 each. Write and solve an inequality that represents the numbers of peppers you can buy.
the inequality would be 18>1.5x
this basically means $18 is greater than or equal to 1.5x, where x is the number of peppers you buy at $1.50 for each pepper. So you can buy any amount of peppers from 0 to 12. If you want to make the inequality better it would be 18>1.5x>0 because you can't buy less than 0 peppers
Factorise:x^2 + 7x + 10 =0
Answer:
x = − 5, − 2
Step-by-step explanation:
x² + 7x + 10 = 0
x² + 5x + 2x + 10 = 0
x(x + 5) + 2 (x + 5) = 0
(x + 5)(x + 2) = 0
x = − 5, − 2

It is estimated that 18 out of every 25 shoppers between the age of 18 and 34 research purchases online before going to a store. What is this value written as a decimal?
Answer: 0.72
Step-by-step explanation:
Given: 18 out of every 25 shoppers between the age of 18 and 34 research purchases online before going to a store.
Fraction of shoppers between the age of 18 and 34 research purchases online before going to a store [tex]=\dfrac{18}{25}[/tex]
In decimal , [tex]\dfrac{18}{25}=\dfrac{18}{25}\times\dfrac{4}{4}=\dfrac{72}{100}=0.72[/tex]
Hence, this value written as a decimal = 0.72
What is the slope of the line graphed
Explain answer
GIVING BRAINIEST
Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, 6) ← 2 points on the line
m = [tex]\frac{6-0}{0+3}[/tex] = [tex]\frac{6}{3}[/tex] = 2
Answer:
The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].
22 = 7 – 3a SHOW ALL WORK
Answer:
a = -5
Step-by-step explanation:
22 = 7 -3a
(subtract 7)
15 = -3a
(divide -3)
a = -5
OR
22 = 7 -3a
(add 3a)
3a + 22 = 7
(subract 22)
3a = -15
(divide 3)
a = -5
Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How much money did the West Raise?
9514 1404 393
Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.

Answer:
1. 795, 23
2. 50, she will finish her candy on November 21 so she won't be able to share with her cousins
3. $276, 71 cars
Step-by-step explanation:
1. your equation: y = 35x + 235
plug in 16 to find how many pictures she will have on may 16: y = 35(16) + 235
you get y = 795
for the second part, you know are trying to find how long it will take to get to 1024 pictures, so you know your y, but you don't know your x
your equation: 1024 = 35x + 235
solve to get x = 22.54
this rounds up to 23, so your answer is 23
2. multiply 8 times 4 to get 32
subtract 32 from 82 to fin how many she has left
you get 50
for the second part, divide 82 by 4 to find how many day it will take to finish her candy
you get 20.5
so no, she will not have candy to share with her cousins, and she will finish her candy on November 21
3. for this, you have a negative y intercept since you need to make $24 to start profiting
your equation: y = 6x - 24
plug in 50 to x: y = 6(50) - 24
you get y = 276
so you make $276 with 50 cars
for the second part, plug in 400 to y: 400 = 6x - 24
solve to get x = 70.66
this rounds up to 71, so your answer is 71
Find the value for x
Can somebody help me?
Please
Answer:
1-7 2-6 3-6 4-4
Step-by-step explanation:
To do this, you must notice that all of these are isosceles triangles (2 of the sides are the same.) You already have 1 value on each triangle, and the length of that side is the same length as the side with the unknown value, so those are the correct answers. If I made a mistake, please correct me. Everybody makes mistakes.

-18w + 6/3
-18w +2
At a food festival, 3/8 of the dishes were from china. Another 12.5% of the dishes were from japan. What percent of the dishes were from the other countries?
Answer: 50%
Step-by-step explanation:
Let x = Total dishes.
Dishes from China = [tex]\dfrac38x[/tex]
Dishes from Japan = [tex]12.5\% \text{ of }x= 0.125x[/tex]
Total dishes from China and Japan = [tex]\dfrac38 x+0.125x=0.375x+0.125x=0.5x[/tex]
Dishes from other countries [tex]= x- 0.5x= 0.5x[/tex]
Percent of dishes from other countries= [tex]\dfrac{0.5x}{x}\times100\%= 50\%[/tex]
Hence, dishes from other countries = 50%

Jim is baking chocolate chip muffins. He has a total of 7 1/3 cups of chocolate chips, if each batch of muffins uses 2/3 of a cup of chocolate chips, enter the most number of batches of muffins Jim can make?
Answer: 11 batches of muffins
Step-by-step explanation:
From the question, we are given the information that Jim is baking chocolate chip muffins and that he has a total of 7 1/3 cups of chocolate chips, and each batch of muffins uses 2/3 of a cup of chocolate chips.
The most number of batches of muffins that Jim can make will be gotten by dividing 7 1/3 by 2/3. This will be:
= 7 1/3 ÷ 2/3
= 22/3 ÷ 2/3
= 22/3 × 3/2
= 11
Jim can make 11 batches of muffins.
