To determine how many biscuits are made from each cup of biscuit mix, divide the total number of biscuits (48) by the total cups of biscuit mix (2 and 2/3) to get 18 biscuits per cup.
The student asked how many biscuits are made from each cup of biscuit mix if a recipe for 48 biscuits uses 2 and 2/3 cups of biscuit mix. To find this out, we need to calculate the number of biscuits per cup of mix.
We start by writing the known ratios that one recipe of 12 biscuits requires 2 cups of flour, and we then scale this to 48 biscuits using unit conversions based on the ratios.
First, we calculate the number of biscuits made per one cup:
Divide the total number of biscuits by the total cups of biscuit mix used.
48 biscuits \/ (2 + 2/3) cups = 48 biscuits \/ (8/3) cups.
Multiply the number of biscuits by the reciprocal of cups:
48 biscuits * (3/8) cups = 18 biscuits per cup.
Therefore, one cup of biscuit mix yields 18 biscuits.

The
OF 406 cm. THE LENGTH OF THE
RECTANGLE IS 7cm LONGER
THAN THE WIDTH. FIND THE
DIMENSIONS OF THE RECTANGLE.
The length of rectangle is 105 cm and width is 98 cm.
Step-by-step explanation:
Given,
Perimeter of rectangle = 406 cm
Let,
w be the width of rectangle
Length of rectangle = w+7
We know that
Perimeter of rectangle = 2(Length + Width)
[tex]406 = 2(w+7+w)\\406 = 2(2w+7)\\406 = 4w+14\\406-14 = 4w\\392=4w\\4w=392[/tex]
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{392}{4}\\w=98[/tex]
Width of rectangle = 98 cm
Length of rectangle = 98+7 = 105 cm
The length of rectangle is 105 cm and width is 98 cm.

The expression represent the value of v is :[tex]v=\sqrt{z(w+z)}[/tex]
The correct option is D
We have the attachment.
As shown, when deconstructing the largest right triangle, we got two similar triangles.
The corresponding sides of similar are proportional. Therefore, we can write the following proportion:
v/ w+ z = z/v
By Cross - multiply, we get:
z(w + z) = [tex]v^2[/tex]
And taking the square root of both sides, we get:
[tex]v=\sqrt{z(w+z)}[/tex]
So, The correct option is D

To simplify the given expression, we first simplify the fraction within the square root, performing the division of similar bases by subtracting exponents. Then, we take the square root of 64 to get 8 and obtain the final simplified expression: 8/x^2y.
Explanation:To solve the specific expression, equivalent to StartRoot StartFraction 128 x Superscript 5 Baseline y Superscript 6 Baseline Over 2 x Superscript 7 Baseline y Superscript 5 Baseline EndFraction EndRoot, we will start by simplification inside the square root bracket. Perform the division with the fractions first. As a general rule, when dividing powers with the same base, we subtract the powers.
We'll start by simplifying 128/2, which is 64. For x Superscript 5 Baseline / x Superscript 7 Baseline, subtract the exponents, which gives us x to the power of -2 (since 5-7 is -2). For y Superscript 6 Baseline / y Superscript 5 Baseline, we also subtract the exponents, which results in y to the power of 1, or simply y.
Hence, the simplified version of the fraction inside the square root is 64x^-2y. Finally, since the square root of 64 is 8, and the square root of any variable raised to the negative power is the reciprocal of the variable, our final simplified expression is 8/x^2y.

A construction manager weighs a bundle of 9 identical bricks and a 7 pound concrete block. The bundle weighs 30 pounds.
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.

if you look 3*3=9 5*3=15 8*3=24 and 10*3=30 so they are taking x*3
Answer:
Y=3x
Step-by-step explanation:
The way a function table works is how x has something done to it to equal y. So if x =4, and y=16
You could formulate the equation y= 4x.
So if we look at the patterns
3 to 9
5 to 15

In November, Mr. Lee’s students read 50 books. In December, they read 40 books.
What is the percent increase or decrease in the number of books they read?
Answer:
20% decrease
Step-by-step explanation:
Start by dividing 40 by 50.
40/50 = 0.8
0.8 is the decimal form of 80%. So now we know that 40 is 80% of 50. This means that the remaining 20% is the difference between the books read in November and December.

A scientist needs 120 ML of a 20% acid solution for an experiment. The lab has available at 10% solution and a 25% solution. How many milliliters of the 10% solution and how many milliliters of a 25% solution should the scientist mix to make the 20% solution?
Answer:
40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.
Step-by-step explanation:
Given:
A scientist needs 120 ML of a 20% acid solution for an experiment. The lab has available at 10% solution and a 25% solution.
Now, to find the milliliters of 10% solution and 25% solution to make 20% solution:
Let the 10% solution be [tex]x.[/tex]
And let the 25% solution be [tex]y.[/tex]
So, total milliliters of solution are:
[tex]x+y=120\\\\x=120-y\ \ \ \ .....(1)[/tex]
Now, to get the milliliters of 10% solution and 25% solution to make 20% solution we solve the equation:
[tex]10\%\ of\ x+25\%\ of\ y=20\%\ of\ 120\\\\\frac{10}{100} \times x+\frac{25}{100} \times y=\frac{20}{100} \times 120\\\\0.10x+0.25y=24[/tex]
Substituting the value of [tex]x[/tex] from equation (1) we get:
[tex]0.10(120-y)+0.25y=24\\\\12-0.10y+0.25y=24\\\\12+0.15y=24[/tex]
Subtracting both sides by 12 we get:
[tex]0.15y=12[/tex]
Dividing both sides by 0.15 we get:
[tex]y=80.[/tex]
Thus, the 25% solution is 80 ml.
Now, substituting the value of [tex]y[/tex] in equation (1) we get:
[tex]x=120-y\\\\x=120-80\\\\x=40\ ml.[/tex]
Hence, the 10% solution is 40 ml.
Therefore, 40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.
A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is the height of the box?
Answer:
The answer is 4√2 ft i.e (5.66ft)
Step-by-step explanation:
The length, width and height of a rectangular box are all perpendicular.
This means the length of the diagonal is the Pythagorean distance of the three sides.
So, square of diagonal = L^2 + W^2 + H^2
So,
100 = 64 + 4 + H^2
H^2 = 100 - 68 = 32
H = √32 = 4√2 = 5.66ft

Nadia says the hypotenuse of the right triangle has a length of 73 because the Pythagorean theorem states that (28+45)squared equals to 73squared. Which describes her solution?
Answer: Her solution is incorrect. The hypotenuse is 53 units
Step-by-step explanation: The error occurred when she quoted the Pythagorean theorem. She added up both sides and squared them and made the answer equal to the square of the hypotenuse. She was supposed to have squared them first, before adding up.
The Pythagorean (or Pythagoras) theorem states that the sum of the squares of two sides of a right angled triangle equals the square of the hypotenuse of the triangle. That is, in triangle ABC, if the hypotenuse is given as line AC, the Pythagoras theorem states that
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse and AB and BC are the other two sides.
In Nadia’s solution, if the hypotenuse is given as 73, and the other two sides are 28 and 45, then the Pythagorean theorem properly expressed would be as follows;
73^2 = 28^2 + 45^2
5329 = 784 + 2025
5329 ≠ 2809
As we have determined, writing out the expression as
73^2 = (28 + 45)^2 is very incorrect as this is not the Pythagorean theorem and of course, the triangle cannot have 73 as its hypotenuse as we have determined by properly writing out the Pythagorean theorem.
The correct solution is as follows;
AC^2 = AB^2 + BC^2
AC^2 = 28^2 + 45^2
AC^2 = 784 + 2025
AC^2 = 2809
Add the square root sign to both sides of the equation
AC = 53
Therefore, the hypotenuse is 53 units
It would be C, because when you find the length using th pythagreon theorem... you can begin to see the relationship through all of the figures and side lengths... Make sense?
