Noah makes an açaí bowl using 1/4 cup of bananas for every 1/3 cup of apple juice. He wants to know the number of cups of bananas per cup of apple juice he uses when making the bowl. Which ratio of cups of bananas to cups of apple juice is equivalent to 1/4: 1/3 ?
Answers
Answer:
3/4 cup of bananas per cup of apple juice.
Step-by-step explanation
1/4 = 1/3x, then solve for x.
1/4 * 3/1 = x
3/4 = x
Ratio of cups of bananas to cups of apple juice is 3 : 4.
What is Ratio?
A ratio indicates how many times one number contain in another
number.
Given that;
Noah makes an bowl using 1/4 cup of bananas for every 1/3 cup of apple juice.
Now,
Ratio of cups of bananas to cups of apple juice = 1/4 : 1/3
= 1/4 ÷ 1/3
= 1/4 × 3/1
= 3/4
= 3 : 4
Thus, Ratio of cups of bananas to cups of apple juice is 3 : 4.

A store sells ½ pound of beef for $0.70. If you are having a party and need 6 pounds of beef for hamburgers, using the unit rate, how much would i cost? Explain.
Answers
Answer:
$8.40
Step-by-step explanation:
A store sells ½ pound of beef for $0.70
We find the unit rate
1/2 pound = $0.70
1 pound =
We cross Multiply
1/2 × x = 1× 0.70
x = 0.70 ÷ 1/2
x = 0.70 × 2/1
x = $1.40
The unit rate for 1 pound of beef is $1.40
If you are having a party and need 6 pounds of beef for hamburgers
Hence, the cost for 6 pounds of beef is:
1 pound = $1.40
6 pounds = y
y = 6 × $1.40
y = $8.40
6 pounds of beef for hamburgers would cost $8.40

Sin(x+y) sin(x-y)=sin²x-sin²y
Answers
Answer:
Step-by-step explanation:
sin(x+y) = sin(x)cos(y) + sin(y)cos(x)
sin(x-y) = sin(x)cos(y) - sin(y)cos(x)
Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))
= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)
= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))
= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)
= sin^2(x) - sin^2(y)

Answer:
See below.
Step-by-step explanation:
t represents time (probably years).
The population of bobcats can't be negative, so negative values in the range do not make sense.
The function is continuous, but you're probably only looking at discrete values.
Answer:

2.t values greater than or equal to 0

If x represents the number of scarves sold and y represents the number of hats
sold, how many scarves and hats did the knitting club sell at the winter festival?
I NEED HOW MANY SCARVES AND HATS WERE SOLD NOT THE SOLUTION
Answers
Answer:
s+h=40 and 18s+14h=700
Step-by-step explanation:
lets say
s= number of scarves sold
and
h=number of hats sold
since the total of hats/scarves equals 40 then that means that scarves+hats sold equals 40 so
s+h=40
the second constraint it found similarly,
scarves and hats are being sold for 18$ and 14$ respectively and together they need to equal 700$ so you plug it into a similar equal as before
18s+14h=700

How to do this question plz answer me
Answers
Answer:
x = 6 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 12 and h = 4, then
A = [tex]\frac{1}{2}[/tex] × 12 × 4 = 6 × 4 = 24 cm²
Then area of parallelogram = 3 × 24 = 72 cm²
The area (A) of a parallelogram is calculated as
A = bh ( b is the width and h the height )
Here b = x and h = 12, thus
12x = 72 ( divide both sides by 12 )
x = 6
The width of the parallelogram is 6 cm
Answer:
6=width
Step-by-step explanation:
Ok so when looking at the question it say that the area of the paraellagram is three times the area of the trianlgle.
-to find the area of a triangle you must use the equation A=1/2LxW would be 24
now once you have 24 you times it by 3 which is 72 (you do this because in the problem it says the paraellagram's area is three times the triangles area so 72 is the paraellagram's area.
now you divide 72 by the only other measurement given to you by the paraellagram which is 12 the length
after dividing the 2 you should get 6 which is the answer
you do this because by dividing 72 by 12 you get the other amount needed to make 72 which was the width
A=1/2(4)x12=24
24x3=7272/12=6

1. A basketball player made 12 out of 15 free throws she attempted. She wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85% (a) Write an equation to represent this situation. (b) Solve the equation. How many consecutive free throws would she have to make to raise her percent to 85%?
Answers
Answer:
She would need to make 5 consecutive free successful throws
Step-by-step explanation:
Equations
A basketball player wants to improve his percent of successful throws to 85%.
She currently has made 12 out of 15 free throws, which gives a success percentage of 12/15*100=80%
So, she needs a number of free consecutive free throws to increase that number to the desired target.
The percentage of success can be calculated as:
[tex]\displaystyle P=\frac{\text{successful throws}}{\text{total throws}}*100[/tex]
Let's assume x is the number of required consecutive successful throws. Since she has already thrown 15 times, out of which has had 12 successful throws, now she will have 15+x total throws and 12+x successes, thus the new percentage is:
[tex]\displaystyle P=\frac{12+x}{15+x}*100[/tex]
And this percentage must be equal to 85%, thus:
[tex]\displaystyle \frac{12+x}{15+x}*100=85[/tex]
a) The equation to represent the situation is:
[tex]\mathbf{\displaystyle \frac{12+x}{15+x}*100=85}[/tex]
b) Let's solve it.
Multiply by 15+x:
[tex]\displaystyle (12+x)*100=85(15+x)[/tex]
Dividing by 5:
[tex]\displaystyle (12+x)*20=17(15+x)[/tex]
Operating:
[tex]\displaystyle 240+20x=255+17x[/tex]
Subtracting 17x and 240:
[tex]\displaystyle 20x-17x=255-240[/tex]
Simplifying:
[tex]\displaystyle 3x=15[/tex]
Dividing by 3:
x = 5
She would need to make 5 consecutive free successful throws
The number of throws is an illustration of proportions.
The number of free throws to raise her percent to 85% is 5
(a) The equation
The proportion is given as: 12 out of 15.
Let the number of throws be n.
So, the proportion would be:
[tex]\mathbf{Proportion = \frac{12 + n}{15 + n}}[/tex]
To make 85% success, then the proportion must equal 85%.
So, we have:
[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]
(b) The solution to the equation
In (a), we have:
[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]
Express 85% as decimal
[tex]\mathbf{\frac{12 + n}{15 + n} = 0.85}[/tex]
Cross multiply
[tex]\mathbf{12 + n = 0.85(15 + n)}[/tex]
[tex]\mathbf{12 + n = 12.75 + 0.85n}[/tex]
Collect like terms
[tex]\mathbf{n -0.85n= 12.75 -12 }[/tex]
[tex]\mathbf{0.15n= 0.75}[/tex]
Divide both sides by 0.15
[tex]\mathbf{n= 5}[/tex]
Hence, the number of free throws to raise her percent to 85% is 5
