Answer:
V≈5.23×10-7m³
Step-by-step explanation:
V=π(d
2)2h=π·(0.014
2)2·3.4×10-3≈5.23389×10-7m³
Answer: 523.1 mm^2
You first want to find the radius for the volume of cylinder formula. You first do 14 divided by 2 to get the radius. You should get 7. Then after you find the radius you then put it into the formula which is v=3.14 x radius^2 x height. The equation with all the numbers from the problem is 3.14 x 7^2 x 3.4. After you put the equation into your calculator you should get 523.1 mm^2.
cookies cost $2.50, where y represents the total cost of x, number of cookies
a. additive
b. Multiplicative
Answer:
Step-by-step explanation:
If the cookies cost $2.50 each, then the total cost of x cookies is
($2.50/cookie)(x), involving multiplication, not addition.
Answer:
Solution :-According to the question
Equation = y/x
Putting y as $2.50
= (2.50)x
And it's a multiplication

Nate is exponentially gaining Twitter followers! His current amount of followers is 146. His followers are increasing at a 24% rate each day. Part 1: Is this a growth or decay problem? ( 1 point) Part 2: Which equation correctly represents this problem (2 points) A) y=146(24)x B) y=146(1.024)x C) y= 146(1.24)x
Answer:
(a) Growth
[tex](b)\ y = 146(1.24)^x[/tex]
Step-by-step explanation:
Given
[tex]a= 146[/tex] -- current
[tex]r = 24\%[/tex] --- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
Hence, it is a growth problem
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:
[tex]y = a(1 + r)^x[/tex]
Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]
[tex]y = 146 * (1 + 24\%)^x[/tex]
[tex]y = 146 * (1 + 0.24)^x[/tex]
[tex]y = 146 * (1.24)^x[/tex]
[tex]y = 146(1.24)^x[/tex]

I think it's -18 13/24 ?
Answer:
-18 13/24
Step-by-step explanation:
Looking at the two numbers, we need to find a common denominator. To do that, list the multiplies of both numbers & find the first one that is in common.
8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120
The first multiple 8 & 6 share is 24, so we'll use that as our denominator
-67/8 - 61/6
-201/24 - 244/24
(-201 - 244)/24
Subtract 244 from -201 to get -445.
-445/24
Convert -445/24 into a mixed number.
-18 13/24 is the answer to -8 3/8 - 10 1/6.

Distance: Jack and Jill start from the same point and walk in'opposite directions. Jack
walks 2 kmh faster than Jill. After 3 hours they are 30 kilometers apart. How fast did
each walk?
Answer:
t = 6 km/hour
And, J would be 4 km per hour
Step-by-step explanation:
Let us assume the speed of Tom be T
And, the Speed of Jim be J
Given that
T - J = 2 km /hr ...........(i)
After 3 hours distance between them = 30 km
As they are walking in the opposite direction
Thus,
Net speed =T + J
L ÷ (T+J) = 3
30 ÷ (T+J) = 3
T +J =10 ..............(2)
After solving these two equations
2T = 12
t = 6 km/hour
And, J would be 4 km per hour

What is the surface area of the triangular prism shown?
A.32 square centimeters
B.120 square centimeters
C.184 square centimeters
D.1,560 square centimeters
NO LINKS TO WEBSITES!!!!!!!!
Answer:
C. 184 square centimeters
Step-by-step explanation:
4 x 6 = 24
there are 2 of them so you leave it the same
5 x 10 = 50
there are 2 of them so
50 x 2 = 100
6 x 10 = 60
24 + 100 + 60 = 184
184 square centimeters
Jack paid $4:00 for 6 pounds of apples. What is the ratio of the price of apples to the pounds of apples?
Answer:
you get 1.5 pounds of apples per dollar (1 pound and 8 ounces)
Step-by-step explanation:
6 and 4 will not work so we need to use decimals
since we have a gap of two, we need to be able to use it four times
2=0.5
1.5 x 4 = 6
or we could just divide it... never mind forget it
your answer is 1.5 pounds of apples per dollar
Answer:
The ratio of the price of apples to the pound of apples: 2:3
Step-by-step explanation:
4:6
divide by 2

what is the slope of 10x-2y=8?
Answer:
Slope: 5
Step-by-step explanation:
Mark as brainllest
Answer:
x= 1 /5 y+ 4 /5
Step-by-step explanation:
Let's solve for x.
10x−2y=8
Step 1: Add 2y to both sides.
10x−2y+2y=8+2y
10x=2y+8
Step 2: Divide both sides by 10.
10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5
