Ed bought 20 cupcakes 30% chocolate and the rest vanilla how many of each cupcake did he buy?
Answer:
he bought 6 chocolate and 14 vanilla !
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
30% of 20 is 6, but since we are trying to find the number of vanilla cupcakes we take the total original number (which was 20), and subtract 6 (the number of chocolate cupcakes). ANSWER- 14

An arrow is shot vertically upward from a platform 35 ft high at a rate of 166 ft/sec. When will the arrow hit the ground? Ignore the air resistance. Use the formula ℎ = −16 2 + 0 + ℎ0. Round your answer to the nearest tenth.
Answer:
The arrow will hit the ground approximately 10.5 seconds after launch.
Step-by-step explanation:
The arrow experiments a free fall motion, which is a particular form of uniform accelerated motion due to gravity and in which air friction and effects from Earth's rotation can be neglected. Then, the height as a function of time ([tex]h(t)[/tex]), measured in feet, is obtained by the following kinematic formula:
[tex]h(t) = h_{o}+v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the arrow, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the arrow, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h(t) = 0\,ft[/tex], [tex]h_{o} = 35\,ft[/tex], [tex]v_{o} = 166\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{m}{s^{2}}[/tex], then the following polynomial is obtained:
[tex]35+166\cdot t -16.087\cdot t^{2}=0[/tex] (2)
Lastly, we find the roots of the given expression by the Quadratic Formula:
[tex]t_{1}\approx 10.526\,s[/tex] and [tex]t_{2} \approx -0.207\,s[/tex]
Time is a positive variable and then we conclude that the only solution that is physically reasonable is approximately 10.526 seconds.
The arrow will hit the ground approximately 10.5 seconds after launch.

Reed has made 78 of 90 attempted free
throws last season. How many
consecutive free throws must he make to
bring his free throw percentage to 90%?
Answer: 81 consecutive free throws
Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.
Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.
What is the slope-intercept equation for the line below? (5, 4) (0, 2) 6 +
O A. y=x+2
O B. y=-x+2
O C. y=-x+2 O 2/
D. y=x+2
Answer:
The answer is D y=2/5x + 2
Step-by-step explanation:
I find the the slope first by using the slope formula y2 - y1/x2 - x1
Then, I use the slope-intercept formula to find the y-intercept
4 = 2/5(5) + b
4 = 10/5 + b
4 = 2 + b
4 - 2 = 2 - 2 + b
2 = b
So u get:
y=2/5x + 2
solve for the given variable
Answer:
30
Step-by-step explanation:
Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!
Answer:
k = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle, thus
k + 90 = 120 ( subtract 90 from both sides )
k = 30

The function f(x)=223(1.09)^x represents the number of specialty items produced at Iron Man’s old factory x weeks after a change in management. The graph represents the number of specialty items produced at the new factory during the same time period.
During Week 0, how many more specialty items were produced at the old factory than at the new factory? Explain.
Find and compare the growth rates in the weekly number of specialty items produced at each factory. Show your work.
When does the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory? Explain.
Answer:
a. 33
b. So we see that at the start of 3rd week, the new factory begins to exceed old production.
Step-by-step explanation:
(a)w = 0
Old factory: p(x)=223(1.09)^x Plug in 0
p(0)= 223(1.09)^(0)
When a number has an exponent of 0, the number becomes 1
p(0) = 223(1)
p(0) = 223
New factory: w = 0, p(0) or y = 190 (0,190)
223 - 190 = 33
During Week 0, 33 more specialty items were produced at the old factory than at the new factory.
(b) i don't know sorry
(c)
The old production tabulated:
w P(w) New
0 223 190
1 243 220
2 265 252
3 289 290
4 315 337
5 343 380
6 374 440
7 408 505
So we see that at the start of 3rd week, the new factory begins to exceed old production.
i hope this helped people in the future.
During week 0 the old factory produced 33 more items than at the new factory.
The weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory at week 4.
What is a function?A function is defined as a relation between a set of inputs having one output each. A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain or range.
According to the given problem,
Specialty items produced at the old factory at week 0,
Given function = [tex]223(1.09)^{x}[/tex]
When x = 0,
f(x) = [tex]223(1.09)^{0}[/tex]
= 223
Specialty items produced at the new factory during 0 = 190
Old factory exceeded the production by:
⇒ ( 223 - 190 )
= 33 specialty items.
Comparing the growth rates of weekly number of specialty items at each factory,
For week 0,
Old factory = 223
New factory = 190
Growth rate = [tex]\frac{223-190}{190}*100[/tex]
≈ 17%
For week 1,
Old factory = 243
New factory = 220
Growth rate = [tex]\frac{243.07-220}{220}*100[/tex]
≈ 10%
For week 2,
Old factory = 265
New factory = 252
Growth rate = [tex]\frac{264.95-252}{252}*100[/tex]
≈ 5%
For week 3,
Old factory = 289
New factory = 290
Growth rate = [tex]\frac{290 -288.79}{288,79}*100[/tex]
≈ 0.41%
For week 4,
Old factory = 325
New factory = 337
Growth rate = [tex]\frac{337-324.78}{324.78}*100[/tex]
≈ 3%
For week 5,
Old factory = 343
New factory = 380
Growth rate = [tex]\frac{380-343.11}{343.11} *100[/tex]
≈ 13%
For week 6,
Old factory = 374
New factory = 440
Growth rate = [tex]\frac{440-374}{374} *100[/tex]
≈ 18%
For week 7,
Old factory = 408
New factory = 505
Growth rate = [tex]\frac{505-408}{408} *100[/tex]
≈ 23%
At week 3, the production at new factory exceeds the production of the old factory.
For old factory,
⇒ f(x) = [tex]223(1.09)^{x}[/tex]
= [tex]223(1.09)^{3}[/tex]
= 289
For new factory at week 3,
Production = 290 items.
Hence, we can conclude, during week 0 the old factory produced 33 more items than at the new factory and the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory at week 4.
