This recipe makes 30 shortbread fingers.
Rose follows this recipe, but only wants to make 6 fingers.
How much of each ingredient does she need?
Recipe: Makes 30
120 g butter
60 g sugar
180 g flour
Answer:
24 g butter
12 g sugar
36 g flour
Step-by-step explanation:
The recipe makes 30 shortbread fingers.
She wants to make 6 fingers.
6/30 = 1/5
She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.
Divide each amount by 5.
Recipe:
Makes 30 30/5 = 6 Makes 6
120 g butter 120/5 = 24 24 g butter
60 g sugar 60/5 = 12 12 g sugar
180 g flour 180/5 = 36 36 g flour
A motorboat leaves a harbor and travels at an average speed of 8 mph toward a small island. Two hours later a cabin cruiser leaves the same harbor and travels at an average speed of 16 mph toward the same island. In how many hours after the cabin cruiser leaves will the cabin cruiser be alongside the motorboat
Answer:
2 hours.
Step-by-step explanation:
From the question given above, the following data were obtained:
Speed of motorboat (sₘ) = 8 mph
Speed of cabin cruiser (s꜀) = 16 mph
From the question given, we were told that the cabin cruiser started his journey 2 hours later after the motorboat has left.
Let t be the time for the cabin cruiser.
Thus, the time for the motorboat will be (2 + t)
Also, if the cabin cruiser and the motorboat must be along side each other, then their distance must be the same.
With the above information, we can obtain the time taken for the cabin cruiser and the motorboat to be along side each other. This can be obtained as follow:
Speed of motorboat (sₘ) = 8 mph
Time for motorboat (tₘ) = t + 2
Speed of cabin cruiser (s꜀) = 16 mph
Time for cabin cruiser (t꜀) = t
Distance of motorboat = distance of cabin cruiser
Recall:
Distance = speed × time
Therefore,
sₘ × tₘ = s꜀ × t꜀
8 × (t + 2) = 16 × t
Clear bracket
8t + 16 = 16t
Collect like terms
16 = 16t – 8t
16 = 8t
Divide both side by 8
t = 16 / 8
t = 2 hours
Thus, it will take 2 hours for the cabin cruiser and the motorboat to be along side each other.
Question 8
A rectangle has vertices at (0,0), (3,0), and (0,6). What is the area
of the rectangle?
I’ll mark you!
Answer:
18 square units
Step-by-step explanation:
The area of a rectangle is simply it's base length multiplied by its height.
A = b × h
Since a rectangle has all right angles, it must have two sets of parallel sides.
Given the coordinates (0, 0), (3, 0), (0, 6) which are vertices of the rectangle. You can find the distance between each point to get the side length and then multiply the two side lengths together.

vertical stretch by a factor of 2; left shift 2 units
Step-by-step explanation:
The transformation ...
g(x) = a·f(b(x -c)) +d
does the following:
vertical stretch by a factor of 'a'horizontal compression by a factor of 'b'translation right by 'c' unitstranslation up by 'd' unitsFor many functions, horizontal coordinate changes are indistinguishable from vertical coordinate changes. Exponential functions tend to be one of those.
__
Using the above notation, you seem to have f(x) = 3^x, and g(x) = 2f(x+2). The transformation is a vertical stretch by a factor of 2, and a translation left 2 units.
__
As with all exponential functions, ...
the domain is "all real numbers"the range is all numbers above the asymptote: f(x) > 0the horizontal asymptote is f(x) = 0The function is a growth function, so ...
x → -∞, f(x) → 0x → ∞, f(x) → ∞_____
Additional comment
The left shift is equivalent to an additional vertical stretch. The function could be rewritten as ...
f(x) = 18(3^x)
with no left shift and a vertical stretch by a factor of 18 instead of 2.
The mean breaking strength of a ceramic insulator must be at least 10 psi. The process by which this insulator is manufactured must show equivalence to this standard. If the process can manufacture insulators with a mean breaking strength of at least 9.4 psi, it will be considered equivalent to the standard. A random sample of 50 insulators is available, and the sample mean and standard deviation of breaking strength are 9.22 psi and 0.24 psi, respectively. a. State the appropriate hypotheses that must be tested to demonstrate equivalence.
Answer:
H0 : u ≥ 10 against the claim Ha: u < 10
Step-by-step explanation:
The mean breaking strength of a ceramic insulator must be at least 10 psi.
(At least means greater or equal to ). As it is already given in the data the null and alternate hypotheses will be formulated according to it.
H0 : u ≥ 10 against the claim Ha: u < 10
The null hypothesis is the mean breaking strength of a ceramic insulator must be at least 10 psi
and the alternate hypothesis is
the mean breaking strength of a ceramic insulator is less than 10 psi

Gabriella can line up her textbooks in 24 different ways on her bookshelf.
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
Gabriella has a Spanish book, a biology book, physics book, and a health text book.
We have;
She has a total of 4 books in her book shelf.
So, the number of positions in which the books have to be put are four.
As we can see,
The books are only one in number each. So, the choices are not repeatable.
So, In first position we have four choices, in third we will be left with three choices, in the seconds position we will have a total of two books as choice and in the last positive we have to put the book that is left.
So, the total different ways in which she can line up her books in the bookshelf are,
= 4×3×2×1
= 24
Thus, There are 24 different ways possible.

Find the value for x.
Answer:
28.5
Step-by-step explanation:
The sum of the interior angles in a triangle is equal to 180
102 + x + 6 + x + 15 = 180
123 + 2x = 180 subtract 123 from both sides
2x = 57 divide both sides by 2
x = 28.5

Example: I had money but won $116 and ended up with a total of $505.
Answer:
I had a great quantity of apples and used 18 to make a large apple pie for my family and I, then I only had 24 left over.
Step-by-step explanation:
X in the equation represents the amount of apples I have at the beginning of the apple pie making process. Minus 18 represents the apples that are being used for the apple pie, so they are not there anymore. 24 represents the apples left over.

GEOMETRY Can anyone help for brainly, this is one of five questions, a (rotation, reflection, or translation) of 90° (clockwise, or counterclockwise,) about the origin followed by a (rotation, reflection, or translation) (right, left, up, down) _ Unit (s)
Answer:
See below-
Step-by-step explanation:
It depends on if you are transforming O to P or P to O
O to P would be rotate counterclockwise translate down 4
using the point (-3,2) from P and it's corresponding point from O (6,3)
rotate 90 counterclockwise (x,y)--> (-y,x) From point O - (6,3)--> (-3,6)
so after the rotation that point would be at (-3,6) to get the point to (-3, 2) move it down 4. so it is translated down 4
if you are transforming O to P is would be the opposite
rotate 90 clockwise and translate up 4
The Barga school grows lettuce and other vegetables for school lunches. The school garden is 8.4 meters long and 6.4 meters wide. The section used to grow lettuce is 2.2 meters long and 0.8 meters wide. How many square meters of garden is not used to grow lettuce?
Answer:
(8.4 * 6.4) - (2.2 * 0.8)
Step-by-step explanation:
52 square meters of garden is not used to grow lettuce.
What is a rectangle?A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
The school garden is in the shape of the rectangle.
The school garden's length = 8.4 meters
The school garden's wide = 6.4 meters
The section used to grow lettuce, length = 2.2 meters
The section used to grow lettuce, width = 0.8 meters
Area of garden is not used to grow lettuce is
⇒ [tex][(8.4)(6.4)-(2.2)(0.8)][/tex]
⇒ [tex][53.76-1.76][/tex]
⇒ [tex]52[/tex]
Hence we can conclude that 52 square meters of garden is not used to grow lettuce.

Find the length of AB?
Given:
The figure of a right triangle.
To find:
The length of AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
Using this trigonometric ratio for the given triangle, we get
[tex]\cos A=\dfrac{AB}{AC}[/tex]
[tex]\cos (60^\circ)=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}\times 10=AB[/tex]
[tex]5=AB[/tex]
Therefore, the length of AB is 5 units.
the average of three numbers is 1/5. Two of the numbers are 1/4 and 1/3. what is the third number?
Answer:
The third number is 1/60
Step-by-step explanation:
Let the denominator of the number = x
1/4 + 1/3 + 1/x = 1/5
1/4 + 1/3 = 3/12 + 4/12 = 7/12
The lowest common denominator is 60x.
(7/12 + 1/x)/3 = 1/5 Remember that this is the average of 3 numbers. That's what the 3 is doing on the left. Multiply both sides by 3
7/12 + 1/x = 3/5 Multiply through by 60x
35x + 60 = 36x
x = 60
