Answer:
370
Step-by-step explanation:
First find the unit rate aka price per pencil: 20 divided by 6 equals 3.333
Then find amount for all pencils
3.333 by 111 is 369.963
Then we round up to have a realistic amount of pencils to 370
A ramp has an angle of inclination of 20 degrees. it has a vertical height of 1.8 m. what is the length, l metres, of the ramp?
Answer:
x = 5.26 m
Step-by-step explanation:
Given that,
The angle of inclination = 20°
The vertical height of the ramp, h = 1.8 m
We need to find the length of the ramp. Let it is x.
We can find it using trigonometry. So,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
We have,
P = 1.8 m, H = x
[tex]\sin20=\dfrac{1.8}{x}\\\\x=\dfrac{1.8}{\sin20}\\\\x=5.26\ m[/tex]
So, the length of the ramp is 5.26 m.

90 students are participating in a contest. There are twice as many girls as boys in this group. Max ranks fourteenth from the top, and there are 10 girls who rank higher than him. How many boys rank lower than Max?
Answer: 57 boys
Step-by-step explanation: Lets break it down right
14th from the top with 10 girls in front which means 3 boys are in front and since there are twice as many girls as boys there are 60 girls and 30 boys so 3 boys are ahead which leaves 57 boys below him
A local car dealership is holding a year-end event because new car models have just been released. Declan has $35,000 to spend on a car. The car Declan decides to buy for his family costs $35,000. However, it is part of the year-end event, which means he receives a 15% discount on the new car. Declan plans to put the money he saves on the car into a new bank account. The bank account has a yearly simple interest rate of 4%, paid at the end of each year. If Declan does not add any other money to this bank account, it will take
Answer:
6 years
Step-by-step explanation:
The computation of the time period is given below:
As we know that
Future value = Present value × (1 + rate of interest)^time period
$6,720 = ($35,000 × 15%) × (1 + 0.04)^time period
$6,720 = $5,250 × 1.04^time period
1.28 = 1.04^time period
So, the time period is 6.29 years i.e. 6 years
hence, the time that should be taken is 6 years

and the sales tax in Somerville is 4%. If Tammy left a 20% tip on the $350, how much in
total did she pay?
Answer:
the other amount of cash she pays equals to 24 percent so times 350 by 1.24 which equals to $434
Answer:434
Step-by-step explanation:
Total price with $350
Sales tax 4% = $14
And tip 20%= $70
Total paid= $434
Find the values of and y the figure given below and choose the appropriate result ABC and XYZ
Answer:
y = 8
x = 17
Step-by-step explanation:
We can find the missing values using similarity ratio
15/30 = y/16 cross multiply expressions
30y = 240 divide both sides by 30
y = 8
Now do the same for x
15/30 = x/34 cross multiply expressions
30x = 510 divide both sides by 30
x = 17
If we had a Pyramid with a hexagonal base, how many of these pyramids would it take to fill up a hexagonal Prism with a congruent base, and equal height?
Answer:
3 of the pyramids
Step-by-step explanation:
Given:
Hexagonal Prism
Hexagonal based pyramid
Required
How many of the pyramid will fill up the prism
To do this, we start by calculating the volumes of both shapes.
Let V1 be the volume of the hexagonal prism
[tex]V_1 = \frac{3\sqrt{3}}{2}a^2h[/tex]
Where: a = base and h = height
Let V2 be the volume of the hexagonal based pyramid
[tex]V_2 = \frac{\sqrt{3}}{2}a^2h[/tex]
Where: a = base and h = height
The number of the pyramid that can occupy the prism is calculated by dividing V1 by V2
[tex]Number = \frac{V_1}{V_2}[/tex]
[tex]Number = \frac{3\sqrt{3}}{2}a^2h /\frac{\sqrt{3}}{2}a^2h[/tex]
Convert division to multiplication
[tex]Number = \frac{3\sqrt{3}}{2}a^2h * \frac{2}{\sqrt{3}a^2h}[/tex]
[tex]Number = \frac{3\sqrt{3}}{2} * \frac{2}{\sqrt{3}}[/tex]
[tex]Number = \frac{3\sqrt{3}}{1} * \frac{1}{\sqrt{3}}[/tex]
[tex]Number = \frac{3*1}{1} * \frac{1}{1}[/tex]
[tex]Number = 3[/tex]

m = -10/4
m = -5/2
m= 0
m = 5/2
Answer:
m= -5/2
Step-by-step explanation:
formula for slope(m) : ΔY/ΔX (change in y coordinates - change in x coordinates)
change in y coordinates: 5-(-5) = 10
change in x coordinates: -4-(0) = -4

C. rectangle
D. semi circle
E. triangle
formulas:
1. A= πr²
2. A= 1/2 base x height
3. A= 1/2 (base 1 + base 2 ) x height
4. A= 1/2 πr²
5. A= length x width
Answer:
Step-by-step explanation:
Circle - A = πr²
Semi circle - A= 1/2 πr²
Trapezoid - A= 1/2 (base 1 + base 2 ) x height
Rectangle - length x width
Triangle - A= 1/2 base x height
Answer:
(see below)
Step-by-step explanation:
A) Trapezoid
3. A = 1/2 (base 1 + base 2 ) x height
~
B) Circle
1. A = πr²
~
C) Rectangle
5. A = length x width
~
D) Semicircle
4. A = 1/2 πr²
This is half of a circle, so it would be 1/2 of the area of a circle, hence the 1/2.
~
E) Triangle
2. A = 1/2 base x height
If you cut a rectangle in half diagonally, you have two triangles. So it's half the area of a rectangle. This is one way to think about it, hence the 1/2.
Solve the system by substitution
10x=y
2x+y=-24
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
The area of a typical eardrum is about 5.00 10-5 m2. (a) Calculate the average sound power incident on an eardrum at the threshold of pain, which corresponds to an intensity of 1.00 W/m2. 5e-5 Correct: Your answer is correct. W (b) How much energy is transferred to the eardrum exposed to this sound for 4.10 min
Answer:
5 * 10^-5 W
1.23 * 10^-2 J
Step-by-step explanation:
Given that :
Area = 5 * 10^-5 m²
Threshold of Pain = Intensity = 1.00 W/m2
Using the relation:
Intensity = power / Area
Hence,
Power = Intensity * Area
Power = 1 W/m² * 5 * 10^-5 m²
Power = 5 * 10^-5 W
Energy transferred to eardrum. Exposed for 4.10 minutes :
Using the relation :
Energy = Power * time
Energy = 5 * 10^-5 * (4.10 * 60 seconds)
Energy = 5 * 10^-5 W * 246 s
Energy = 0.0123
= 1.23 * 10^-2 J
