In a bag there are blue sweets, red sweets and yellow sweets. The number of blue sweets is four times the number of yellow sweets. The number of red sweets is half the number of yellow sweets. Find the percentage of sweets in the bag that are yellow.
Answer:
18.18%
Step-by-step explanation:
The percentage of sweets in the bag that are yellow is as follows:
Let us assume the number of yellow sweets be x
So for number of blue sweets be 4x
And, the number of red sweets be 0.5x
So it could be written as
Blue Red Yellow
4 0.5 1
8 1 2
So for yellow, the percentage is
= 2 ÷ (8 + 1 + 2)
= 2 ÷ 11
= 18.18%

Michelle's father deposited $1,000 into a savings account when she was born. The annual interest rate is
4.5%. Since opening the account, Michelle's father has never deposited or withdrawn money from it.
What age will Michelle be when her account reaches more than $2,000?
Answer:
Michelle's age = 16
Step-by-step explanation:
As we know,
Amount = [tex]P (1 + r)^{t}[/tex] where
P = Principal amount
r = rate of interest
t = time
Given ,
P = $1000
r = 4.5 % = [tex]\frac{4.5}{100} = 0.045[/tex]
Now,
Given that Amount reaches more than $2000
⇒[tex]P (1 + r)^{t}[/tex] > 2000
⇒[tex]1000(1 + 0.045)^{t}[/tex] > 2000
⇒[tex](1.045)^{t}[/tex] > 2
Now,
we put the value of t from 0 , 1, 2, ..... untill the above equation does not satisfy
Now,
for t = 0
[tex](1.045)^{0} = 1 \ngeq 2[/tex]
for t = 1
[tex](1.045)^{1} = 1.045 \ngeq 2[/tex]
for t = 2
[tex](1.045)^{2} = 1.092 \ngeq 2[/tex]
for t = 3
[tex](1.045)^{3} = 1.14 \ngeq 2[/tex]
for t = 4
[tex](1.045)^{4} = 1.19 \ngeq 2[/tex]
for t = 5
[tex](1.045)^{5} = 1.25 \ngeq 2[/tex]
for t = 6
[tex](1.045)^{6} = 1.30 \ngeq 2[/tex]
for t = 7
[tex](1.045)^{7} = 1.36 \ngeq 2[/tex]
for t = 8
[tex](1.045)^{8} = 1.42 \ngeq 2[/tex]
for t = 9
[tex](1.045)^{9} = 1.48 \ngeq 2[/tex]
for t = 10
[tex](1.045)^{10} = 1.55 \ngeq 2[/tex]
for t = 11
[tex](1.045)^{11} = 1.62 \ngeq 2[/tex]
for t = 12
[tex](1.045)^{12} = 1.69 \ngeq 2[/tex]
for t = 13
[tex](1.045)^{13} = 1.77 \ngeq 2[/tex]
for t = 14
[tex](1.045)^{14} = 1.85 \ngeq 2[/tex]
for t = 15
[tex](1.045)^{15} = 1.93 \ngeq 2[/tex]
for t = 16
[tex](1.045)^{16} = 2.02 > 2[/tex]
It satisfies at t= 16
∴ we get
Michelle's age = 16

A car and a motorcycle leave the city at the same time and drive to a lake that is 120 km away. The speed of the motorcycle is 20 km per hour greater than the speed of the car, so the motorcycle arrives at the lake 1 hour before the car. Find the speed of the car and the speed of the motorcycle. Plz answer fast!!
Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h

As, we have :
Students present on Monday = [tex] \tt \dfrac{5}{7} of 35[/tex]
[tex] \\ [/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{7} \times 35[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{\cancel{7}} \times \cancel{35}[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = 5 \times 5[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = 25[/tex]
[tex] \\ [/tex]
Now, we have to find students not present on Monday :
As, we have :
Total number of students = 35 Students present on Monday = 25[tex] \\ [/tex]
Therefore,
Students absent on Monday = 35 - 25 = 10

Hence, 10 students were not present on Monday.

If you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Complete question :
Mitch is making birdhouses to sell. He needs to make at least $678. Each birdhouse costs $28 to make. He is selling them for $40 each. What is the minimum he can sell to reach his goal?
Answer:
57
Step-by-step explanation:
you need to make $678 and it costs $28 to make it and you are selling it for $40 each .. What is the minimum you have to sell
Target profit = $678
Expenses per product = $28
Income per sale = $40
Profit per sale = $(40 - 28) = $12
Let number of sales or product = x
Hence,
$12 * x ≥ 678
12x ≥ 678
x ≥ 678 / 12
x ≥ 56.5
To the nearest whole number = 57
you invest 10000 that will earn 8.3% every year how much will you earn in 12 years.
Answer:
$16034.03
Step-by-step explanation:
I'm going to assume it's compound interest
10000(1+.083)^12
26034.03
subtract the original amount to find out how much was earned
26034.03-10000=16034.03
Answer:
$9960 would be earning in 12 years
Step-by-step explanation:
8.3% of 10,000 is 830
1% of 10,000 is 100
.3 would just be 30
.4 would be 40
etc etc
so 830 times 12(years) is $9960.00
The height odf a regtangular pyramid is 4 inches. The base of the pyramid measures 9 inches by 9 inches. What is the volume of the rectagular pyramid in cubic inches?
Answer:
[tex]V=108\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
The height of a rectangular pyramid is 4 inches
The base of the pyramid measures 9 inches by 9 inches.
We need to find the volume of the rectangular pyramid. The formula for the volume of the rectangular pyramid is given by :
[tex]V=\dfrac{lbh}{3}[/tex]
Substitute all the values,
[tex]V=\dfrac{4\times 9\times 9}{3}\\\\V=108\ \text{inches}^3[/tex]
So, the volume of the rectangular pyramid is [tex]108\ \text{inches}^3[/tex].

HELP ASAP PLEASE! I need to write an equation of the line in slope-intercept form.
Answer:
y=2x-2
Step-by-step explanation:
The slope-intercept form is known as y=mx+c
y= the y coordinate
m= the gradient/slope
x= the x coordinate
c= y intercept
The y intercept is when the line crosses the y axis. The graph shows the y intercept is (0,-2). This means our value of c is -2.
Now we must find the value of m. The value of m is the slope of the graph. I usually figure out the slope by doing the change in y / change in x (by counting along how many squares). The change in y is two squares up and the change in x is one square along.
Therefore, the gradient would be 2/1. This equals 2 (so m=2).
Now, we can easily substitute these values into the equation given earlier. Therefore, the equation would be y=2x-2.
