Step-by-step explanation:
Malcolm is driving 1, 273 miles from Wichita to Charleston for a family reunion. He drives 418 miles the first day and 384 miles the second day. Round each distance to the nearest ten and estimate about how many miles Malcolm has left to drive.
400 miles
500 miles
470 miles
480 miles
Answer:
Step-by-step explanation:
418 to the nearest ten is 420
384 to the nearest ten is 380
1273 to the nearest ten is 1270
1270-(420+380)=1270-800=470 miles

The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 2:5
Surface area: 80
volume: 352
Surface area: ?
volume: ?
Answer:
Surface area: 500
Volume: 5500
Step-by-step explanation:
Scale factor: 2:5
This means that the dimensions of the larger figure are 5/2 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/2) by the original surface area(80). So
[tex]S = (\frac{5}{2})^2 \times 80 = \frac{25}{4} \times 80 = 25 \times 20 = 500[/tex]
Volume:
The volume is found multiplying the cube of the change(5/2) by the original volume(352). So
[tex]S = (\frac{5}{2})^3 \times 352= \frac{125}{8} \times 352 = 125 \times 44 = 5500[/tex]

Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e2t 1 bacteria per hour. Find the population size after four hours
Complete Question
Bacteria culture A culture of the bacterium Rhodobacter sphaeroids initially had 30 bacteria and t hours later increases at a rate of 2e^2t 1 bacteria per hour. Find the population size after four hours
Answer:
3010
Step-by-step explanation:
We were given the rate: 2e^2t
Step 1
We would integrate
P = Population
dP/dt = 2e^2t
dP =( 2e^2t) dt
∫dP = ∫ 2e^2t dt
P(t) = (2e^2t)/2 + C
P(t) = e^2t + C
Step 2
We solve for C
The culture initially has 30 bacteria
When t = 0
P(0) = 30
P(0) = e^2t + C
30 = e^2× 0 + C
30 = 1 + C
C = 30 - 1
C = 29
Step 3
Find the population size after four hours
t = 4, C = 29
P(t) = e^2t + C
P(4) = e^2 × 4 + 29
P(4) = e^8 + 29
P(4) = 3009.957987
Approximately = 3010 bacteria
find the value of p in parallelogram
Answer:
p = 11
Step-by-step explanation:
In a parallelogram BA and CD are parallel so you would set the problem up 7p = p +66
- p both sides
6p = 66
divide 6 both sides
p = 11

The picture above
Answer:
X is equal to 12°
Step-by-step explanation:
From the picture we can make the following equation...
90° = 3x + (x + 42°)
90° = 3x + x + 42°
4x = 90° - 42°
4x = 48°
x = 12°

James earned 96$ by mowing his neighbor yard. He spent 50% of his money on a video game. He is going to save 75% of his remaining money. How much would he save
Answer:
36
Step-by-step explanation
Subtract 50% from $96.00
96.00 - 48.00 = 48.00
Find out what is 75% of 48
48.00 - 75% = 36
Solve for n in each of the following equations:
(a)
n^ Pbase2=110
Answer:
[tex]n = 11[/tex]
Step-by-step explanation:
Given
[tex]^nP_2 = 110[/tex]
Required
Solve for n
[tex]^nP_2 = 110[/tex]
Start by applying permutation formula:
[tex]\frac{n!}{(n-2)!} = 110[/tex]
Expand the numerator
[tex]\frac{n*(n-1) * (n-2)!}{(n-2)!} = 110[/tex]
(n-2)! cancels out
[tex]n*(n-1) = 110[/tex]
Expand
[tex]n^2 - n = 110[/tex]
Subtract 110 from both sides
[tex]n^2 - n -110= 110-110[/tex]
[tex]n^2 - n -110= 0[/tex]
Expand:
[tex]n^2 - 11n +10n-110= 0[/tex]
Factorize:
[tex]n(n-11) +10(n-11)= 0[/tex]
[tex](n+10)(n-11) = 0[/tex]
This implies that:
[tex]n + 10 = 0\ or\ n - 11 = 0[/tex]
[tex]n = -10\ or\ n = 11[/tex]
But n can't be negative.
So:
[tex]n = 11[/tex]
