What is the exact volume of the cone? A. 40n cm3 B. 80/3 n cm3 C. 160/3 n cm3 D. 160n cm3
Answer:
167.55
Step-by-step explanation:
Formula - V = [tex]\pi r^2\frac{h}{3}[/tex]
V = [tex]\pi (4)^2\frac{10}{3}[/tex]
V = 167.55
Edith rides in an Oober that charges a flat rate of $6.75 plus $3.20 per mile. If the ride share service charges $40.03 in total for her trip, how many miles is her ride? Enter your NUMERICAL answer only in the box as a decimal to the nearest tenth of a mile.
Answer:
10.4 miles
Step-by-step explanation:
c(m) = trip cost
c(m) = 6.75 + 3.2m
40.03 = 6.75 = 3.2m
33.28 = 3.2m
m = 10.4
[tex]-2\sqrt{18} +2\sqrt{2}[/tex]
Answer:
- 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify [tex]\sqrt{18}[/tex] using this rule
[tex]\sqrt{18}[/tex]
= [tex]\sqrt{9(2)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]
Then
- 2[tex]\sqrt{18}[/tex] + 2[tex]\sqrt{2}[/tex]
= - 2(3[tex]\sqrt{2}[/tex] ) + 2[tex]\sqrt{2}[/tex]
= - 6[tex]\sqrt{2}[/tex] + 2[tex]\sqrt{2}[/tex]
= - 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:
The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.
Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today
Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t

Answer:
Here is the step: Area of triangle = 1/2 (height x base) = 1/2 (9 x 18) = 81
Step-by-step explanation:
Then the Area of the rectangular = 12 x 18 = 216
So the total Area of the figure is = 81 + 216 = 297

Answer:
the angle is = 50
Step-by-step explanation:
8x+2+70+60=180° (interior angles of a triangle add up to 180°)
8x+132=180
8x=180-132
8x=48
divide with the coefficient of x both sides
x=6
substitute
(8(6)+2)+70+60=180
50+70+60=180
180=180
Randy drew a rectangle inside another with the size shown below on a piece of paper. He places the paper outside during a light rain. What is the approximate probability that a raindrop that lands on the paper will fall outside the shaded region?
Answer:
[tex]Probability = 84\%[/tex]
Step-by-step explanation:
First, calculate both areas
[tex]Area = Length * Width[/tex]
The area of the outer rectangle is:
[tex]Big\ Area = 20 * 25[/tex]
[tex]Big\ Area = 500cm^2[/tex]
The area of the small rectangle is:
[tex]Small\ Area = 10 * 8[/tex]
[tex]Small\ Area = 80cm^2[/tex]
The area outside the small rectangle is:
[tex]Outside = Big - Small[/tex]
[tex]Outside = 500cm^2 - 80cm^2[/tex]
[tex]Outside = 420cm^2[/tex]
So, the probability that it falls outside the paper inside is:
[tex]Probability = \frac{Outside}{Big\ Area}[/tex]
[tex]Probability = \frac{420cm^2}{500cm^2}[/tex]
[tex]Probability = \frac{420}{500}[/tex]
[tex]Probability = 0.84[/tex]
Express as percentage:
[tex]Probability = 0.84*100\%[/tex]
[tex]Probability = 84\%[/tex]

Answer:
B
Step-by-step explanation:
it is important to note that 40/8 = 5.
A real number is one that can be found on the number line, and 5 can be.
A rational number can be made by dividing two integers (40 by 8 in this case).
5 is a whole number since it does not have a decimal/fractional part
an integer is a whole number which is positive/negative (5 is positive in this case)

to insure goods to send them overseas it costs the exporter 5/2% of the value of the goods. if the goods are valued at 16.400$, what will be the insurance cost?
Answer:
The insurance costs to send goods valued at $16,400 is $410
Step-by-step explanation:
The amount it costs an exporter to insure goods to send overseas = (5/2)% of the value of the goods
Therefore;
The insurance costs, 'C' to send goods valued at $16,400 is given as follows;
C = $16,400 × (5/2)/100 = $410
The insurance costs to send goods valued at $16,400 = $410

1. A square and a rectangle have the same area. The length of the rectangle is 32
centimeters, and the width of the rectangle is 2 centimeters. What is the length, in
centimeters, of a side of the square?
Answer:
8
Step-by-step explanation:
A=l*w
32*2=64
A=s*s
s=√A
√64
=8
The length in centimeters of the side of the square is 8 cm.
What is the area of a rectangle and a square?The area of a rectangle and a square are -
A{R} = Length x Breadth
A{S} = Side x Side
Given is that a square and a rectangle have the same area. The length of the rectangle is 32 cm and the width of the rectangle is 2 cm.
It is given that -
A{R} = A{S}
Length x Breadth = Side x Side
32 x 2 = (Side)²
(Side)² = 64
Side = 8
Therefore, the length in centimeters of the side of the square is 8 cm.

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?
find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
Answer:
AREA OF LARGE BUBBLE=PI×R^2
AREA OF 1 SMALL BUBBLE =PI×r^2
then area of 4 small bubble =(PI×r^2)×4
now,
area of large bubble =area of 4 small bubble
PI×R^2=4×(PI×r^2)
R= 10 cm

Find the surface area
Please explain
Step-by-step explanation:
There are two trapezium(s), area of 2:
= 2 [½ x (sum of || sides) x height]
= 2[½ x (4 + 8) x 4.6 ] [not clearly visible if it is 4.5 or 4.6]
= 55.2 yd²
Area of vertically tilted rectangles
1): area = 5 x 4 = 20 yd²
2): area = 5 x 4 = 20 yd²
Total area = 20 + 20 = 40 yd²
Area of horizontal rectangles:
1): area = 4 x 8 = 32 yd² [upper]
2): area = 4 x 4 = 16 yd² [lower]
Area of given surface = 55.2 + 40 + 32 + 16 = 143.2 yd²
what is the surface area of this design?
Answer:
197 in
Explanation:
6.4x5=32
9x5=45
5×5=25x4=100
5×4×0.5=10×2=20
32+45+100+20=197
Answer:
197 inches squared
Step-by-step explanation:
Break down the sides,
Side 1, (front) 5*5=25
Side 2, (slanted compound shape) break down compound into triangle and square: 5*5=25, 4*5/2=10
Side 3, (slanted compound shape) break down compound into triangle and square: 5*5=25, 4*5/2=10
Side 4, (top slanted) 6.4*5=32
Side 5, (Bottom) 5*5=25
Side 6, (Back) 9*5=45
Add all together, 25+25+10+25+10+32+25+45=197
