18 rice cakes weigh a total of 130 g. There are 329 calories in 100 g of rice cakes. How many calories are there in one rice cake?
Answer:
1 rice cake has 23.761 calories
Step-by-step explanation:
18 rice cakes weigh a total of 130 g.
There are 329 calories in 100 g of rice cakes.
Step 1
We calculate the number of calories is 18 rice cakes
18 rice cakes = 130g
Hence,
100g = 329 calories
130g = x
Cross Multiply
100g × x = 130g × 329 calories
x = 130g × 329 calories/100g
x = 427.7 calories
Therefore, 18 rice cakes had 427.7 calories
Step 2
How many calories are there in one rice cake?
18 rice cakes = 427.7 calories
1 rice cake = x
Cross Multiply
18 × x = 1 × 427.7
x = 427.7/18
x = 23.761111111 calories
Approximately = 23.761 calories
Therefore, 1 rice cake has 23.761 calories

a reflection of the pink triangle is shown. which transformation makes this reflection
Answer:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
f(x) = 3x + 1, solve for x when f (x) =7.
Answer: x=2
Step-by-step explanation:
Given
f(x)=3x+1
f(x)=7
Combine two equations by substitution
3x+1=7
Subtract 1 on both sides
3x+1-1=7-1
3x=6
Divide 3 on both sides
3x/3=6/3
x=2

Answer:
65:55, 55:65, 55:120
Step-by-step explanation:
Fiberglass boats are = 65 because 120-55=65
Fiberglass to wood means that there is a 65:55 ratio because there are 65 fiberglass boats and 55 wood boats
wood to other, this is kind of a trick question, but its 55:65 because there are 65 other boats and 55 wooden boats
wood to total, this is 55:120 there are 55 wood boats and 120 total boats.

9) A cow is tethered with a rope 20 ft long. What is the maximum area the cow can graze?
Answer:
If the rope is 20 ft long, then the maximum area the cow can graze is:
[tex]\pi \\[/tex]r^2 square feet.
[tex]\pi[/tex] is approximately 3.14, so that means we have: 3.14(20^2) = 1256 ft squared.
Thus, the maximum area that the cow can graze is 1256 ft squared.
Let me know if this helps!
The cow's maximum grazing area is 1256 ft squared. The grazing area is found as the area of the circle.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
If the rope is 20 feet long, the cow can graze the following area:
A=πr²
A=3.14(20)²
A=1256 ft squared.
As a result, the cow's maximum grazing area is 1256 ft squared.

(a) Reflect the point (7, -9) across the y-axis:
(b) Reflect the point (7, -9) across the x-axis:
Answer:
(-7,-9) and (7,9)
Step-by-step explanation:7,-9 so we do across the x so you need a graph for this now x goes left so we plot the coordinates in the third box 7,-9 is in the 4 box so after we plotted that you can see it reflects.Now y coordinate since the y line goes up we plot the coordinates on top of the 4 box where our original coordinates stay now it should be 7,9 the y becomes positive which is 9.

A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
Answer:
8 batches
Step-by-step explanation:
A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
From the above question, 1 recipe = 1 batch of cookies
Hence:
2/3 cup of sugar = 1 batch of cookies
5 1/3 cups of sugar = x batches of cookies
Cross Multiply
2/3 cup × x batches = 5 1/3 cup × 1 batch
x batches = 5 1/3 cup × 1 batch/2/3 cup
x batches = 16/3 ÷ 2/3
x batches = 16/3 × 3/2
= 8 batches
Therefore she made 8 batches

Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be

What is the equation for the nth term of the sequence
And what is the 52nd term of the sequence. -8,-12,-16
Given:
The sequence is -8, -12, -16.
To find:
The nth and 52th term of the given sequence.
Solution:
We have,
-8, -12, -16
It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is
[tex]r=a_2-a_1[/tex]
[tex]r=-12-(-8)[/tex]
[tex]r=-12+8[/tex]
[tex]r=-4[/tex]
The nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is first term and d is common difference.
Putting a=-8 and d=-4, we get
[tex]a_n=-8+(n-1)(-4)[/tex]
[tex]a_n=-8-4n+4[/tex]
[tex]a_n=-4-4n[/tex]
Putting n=52, we get
[tex]a_{52}=-4-4(52)[/tex]
[tex]a_{52}=-4-208[/tex]
[tex]a_{52}=-212[/tex]
Therefore, the equation for the nth term of the given sequence is [tex]a_n=-4-4n[/tex] and the 52nd term of the sequence is -212.

Hiya! Here's my question:
A baker uses 80 grams of salt for each batch of bread. Salt comes in a 32-kilogram package or a 1,700-gram package. Which size package should the baker buy so that no salt is left after all of the batches are made? Explain.
(I really need to answer this quickly, thanks! ^^)
wait i got it!
Since 18 kilograms are 18000 grams, you have
18000/30=600
and
800/30=26.6
So, with 18 kilograms of salt the baker can make exactly 600 batches with no leftovers, while with 800 grams of salt the baker can make 26 batches, with some leftovers.
In fact, 26 batches require
26 x 30 =780
grams of salt, and the remaining
800-780=20
grams of salt are not enought to prepare the next batch
