Answer:
216 cookies
Step-by-step explanation:
From the question,
Let the total cookies in the first place be x cookies.
Their ratio = 5:12:9
Total = 5+12+9 = 26.
Weiming share = (5/26)x = 5x/26
If weiming sold 28 cookies
⇒ (5x/26)-28
⇒ (5x-728)/28
Hence Weiming new share = (5x-728)/28 cookies
The new ratio is 1:8:6
The total cookies becomes = x-28
Therefore,
(1/15)(x-28) = (5x-728)/28
(x-28)/15 = (5x-728)/28
Crossmultiply
28(x-28) = 15(5x-728)
28x-784 = 75x-10920
Collect like terms
28x-75x = -10920+784
-47x = -10136
x = -10136/-47
x = 215.7
x ≈ 216 cookies

Calculate the volume of a prism with a length of 7/8ft, width 2/3 ft and height 1/2 ft. BE SURE TO EXPLAIN ALL STEPS
Answer:
14/48 Feet
Step-by-step explanation:
First, you multiply 7/8x2/3 which equals 14/24, which makes the base of the prisim 14/24 feet. Then you need to multiply 14/24 ( the base) by 1/2 (the height). 14/24x1/2= 14/48.
The final answer is 14/48.
Steve gets paid $50 a week plus $5 for each item he sells. He wants to know how many items he needs to sell, x, to make at least $220 in one
week
Select all the inequalities that represent the situation
HELLPPPPP
Answer:
Steve needs to sell 34 items.
Step-by-step explanation:
S= 5x+50
220=5x+50
-50 -50
170= 5x
/5 /5
34 = x
Check:
220= 5(34)+50
220=170+50
220=220

Answer:
C
Step-by-step explanation:
A function means that a graph cannot have repeating x values, so to test if something is a function we do the horizontal line test. You simply draw a vertical line and if the graph touches it twice it is not a function.
Jenny ran 4 4/5 miles on Saturday and 6 2/5 miles on sunday. How many miles should she run on monday if she wants her average run for the three days to be 5 miles
Answer:
3.8 miles
Step-by-step explanation:
Given data
Saturday= 4 4/5 miles= 24/5= 4.8 miles
Sunday= 6 2/5 miles = 32/5=6.4 miles
Monday= x miles
Average= 5 miles
We know that
Average= Sum of data/Number of data
5= 4.8+6.4+x/3
cross multiply
5*3= 4.8+6.4+x
15= 11.2+x
x= 15-11.2
x=3.8 miles

Aiden and his sister saved 360 quarter altogether. Aiden saved twice as many quarters as his sister, If Aiden plans to put his quarter into 3 equal piles, how many quarters will he put in each pil.
Answer:
Aiden and his sister have 360 quarters together. If Aiden has twice as much as his sister, he has 180 quarters.
360/2 = 180
Aiden divides his quarters into 3 equal piles.
180/3 = 60
Aiden has 60 quarters in each of his 3 piles.
Does anyone understand this?

two more than a certain number is 15 less than the product of 7/8 and the number
equation
Answer:
The number is -136.
Step-by-step explanation:
Let the number be x, so we have the equation:
x + 2 = 7/8 x - 15
x - 7/8 x = -15 - 2
1/8 x = -17
x = -17 * 8 = -136.

Antoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00.
Tess says, “It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get 4 dollars and 60 cents + 4 dollars and 60 cents = 9 dollars and 20 cents for the 15% gratuity.”
How should Antoine respond to Tess’s method?
“Tess, the best way to find 15% of $46.00 is to multiply StartFraction 1 over 15 EndFraction by $46.00 to get $3.07, which is the 15% gratuity.”
“Tess, you found 20% of the number because you added 10% and 10%. You need to add 10% to One-half of 10%. Add $4.60 and $2.30 to get $6.90, which is the 15% gratuity.”
“Tess, the best way to find 15% of $46.00 is to multiply 0.015 and 46.00 to get $0.69, which is the 15% gratuity.”
“Tess, you should use a table with 5% segments to find the gratuity. Each 5% segment has a value of $9.20, so that is the 15% gratuity.”
Answer:
How would Antonio respond....she would say "Thanks for the practice ".
Tess is right about it being easy to find 10% of 46 by moving the decimal point 1 place to the left to get 4.60.....but there is no need to do that twice....because if u do 10% twice, ur doing 20%.
okay....once u get 10% of 46 = 4.60....then u figure 5% of 46 = (0.05(46) = 2.30....because 10% + 5% = 15%.....then u add those together.....4.60 + 2.30 = 6.90. This can easily be checked...15% of 46 = 0.15(46) = 6.9 ,just like 10% of 46 + 5% of 46 = 6.9

Step-by-step explanation:
Two similar polygons are shown below. Find the value of x and y.
Answer:
x = 18, y = 12
Step-by-step explanation:
Δ SRT and Δ VUT are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{SR}{VU}[/tex] = [tex]\frac{ST}{VT}[/tex] , substitute values
[tex]\frac{12}{4}[/tex] = [tex]\frac{x}{6}[/tex] ( cross- multiply )
4x = 72 ( divide both sides by 4 )
x = 18
From side ST
y + 6 = 18 ( subtract 6 from both sides )
y = 12

Answer:
1. 16, 19, 21
2. 81, 243, 729,
3. 25, 31
4. 20/24, 19/24
5. 37
Step-by-step explanation:
1. The numbers are going up by +3 ( 1 + 3 = 4, 4 + 3 = 7 etc..)
2. The numbers are being multiplied by 3 ( 3 x 3 = 9, 9 x 3 = 27 etc..)
3. Numbers are going up by +2
4. Numbers are decreasing by 1/24 ( 23/24 - 1/24 = 22/24 etc..)
5.
12 - 7 = 5
22 - 12 = 10 (5*2)
82 - 57 = 25 (5*5)
We can see a pattern here and the pattern is that the numbers are increasing according to the x5.
Hence 22 + (5*3) = 37

What is the sum of (3x^2+ 5x +6) and (25x^3+ 10x² + 7x– 3)
Answer:
25x³ + 13x² + 12x + 3
Step-by-step explanation:
(3x²+ 5x +6) + (25x³ + 10x² + 7x– 3)
3x²+ 5x + 6 + 25x³+ 10x² + 7x – 3
25x³ + 3x² + 10x² + 5x + 7x + 6 - 3
25x³ + 13x² + 12x + 3
(Part A)Find the area of the circle with a radius of 4m.
(Part B)Find the circumference of the circle with a radius of 4 m.
Step-by-step explanation:
Part A)
Area of Circle =
[tex]\pi {r}^{2} \\ = \pi( {4}^{2} ) \\ = 16\pi {m}^{2} [/tex]
Part B)
Circumference of Circle =
[tex]2\pi \: r \\ = 2\pi(4) \\ = 8\pi \: m[/tex]
Answer:
Part A: 16π m²
Part B: 8π m
Step-by-step explanation:
Part A
[tex]A=\pi r^2[/tex] where r is the radius
Plug in 4 as the radius
[tex]A=\pi (4)^2\\A=\pi(16)\\A=16\pi[/tex]
Therefore, the area of the circle is 16π m².
Part B
[tex]C=2\pi r[/tex] where r is the radius
Plug in 4 as the radius
[tex]C=2\pi (4)\\C=8\pi[/tex]
Therefore, the circumference of the circle is 8π m.
