can yoy please help solve yhis problem.2/5b+1=11
Answer:
(2/5)*b+1 = -11 // + 11
(2/5)*b+1+11 = 0
2/5*b+12 = 0 // - 12
2/5*b = -12 // : 2/5
b = -12/2/5
b = -30
b = -30

What is the quotient of 2/3/4 ÷ 1/4
Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11

Connie deposited $1200 in a new account that earns 3% simple interest. After 7 years, how much interest will she have earned?
Answer:
$252
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 1200 × 0.03 × 7 = 252
I = $ 252.00
The simple interest accumulated
on a principal of $ 1,200.00
at a rate of 3% per year
for 7 years is $ 252.00.
2/5 kilogram of soil fills 1/3 of a countainer. Can 1 kiligram of soil fit in the container?
Answer:
Yes
Step-by-step explanation:
If 2/5kg fills one third, let's multiply 2/5kg by 3 to find out how much soil the conatainer can hold.
(2/5kg)(3) = 9/5kg = 1.8kg
1.8kg>1kg, so the answer is yes

Emily pays $24 to rent a boat at the lake for up to 6 hours. She constructs the inequality and number line below to represent the number of hours, x, she can use the boat.
Answer:
Emily's inequality x < 6 is correct because the number of hours is less than or equal to.
Emily's number line is incorrect The endpoint is filled in and the number line is greater than the endpoint.
Step-by-step explanation:
Emily's Model:
x < 6
<----|----|----|----|----|----⊕----|----|----|----|----|----|----|----|---->
1 2 3 4 5 6 7 8 9 10 11 12 13 14
What Emily's model should look like to make the number line true:

How do I find the density? Harold is a woodworker and is interested in finding the density of two different types of wood. He bought a pine log that has a 5-inch radius and is 30 inches long. The weight of the log is approximately 42.63 pounds.
Answer:
The density of the pine log is 0.2842 pounds per inch.
Step-by-step explanation:
To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:
X = 42.63 / (30 x 5)
X = 42.63 / 150
X = 0.2842
Thus, the density of the pine log is 0.2842 pounds per inch.

Decrease £19064.67 by 19.5%
Give your answer rounded to 2 DP
G
£
Answer:
£15347.07
Step-by-step explanation:
Given data
Amount=£19064.67
% decrease=19.5%
let us find the value of 19.5%
=19.5/100*19064.67
=0.195*19064.67
=£3717.6
Hence the new Amount after the decrease is
=19064.67-3717.6
=£15347.07
A graphing calculator is recommended. A bacteria culture starts with 300 bacteria and doubles in size every half hour. (a) How many bacteria are there after 2 hours? bacteria (b) How many bacteria are there after t hours? y = bacteria (c) How many bacteria are there after 40 minutes? (Round your answer to the nearest whole number.)
Answer:
a) 4800 bacteria
b) [tex]y(t) = 300(4)^t[/tex]
c) 754 bacteria
Step-by-step explanation:
A bacteria culture starts with 300 bacteria and doubles in size every half hour.
This means that the number of bacteria after t periods of half hour is given by:
[tex]y(t) = 300*(2)^{t}[/tex]
(a) How many bacteria are there after 2 hours?
2 hours is 2*60/30 = 4 periods of 2 hours, so this is y(4).
[tex]y(4) = 300*(2)^{4} = 300*16 = 4800[/tex]
(b) How many bacteria are there after t hours?
It doubles every half hour, so each hour, it is multiplied by 4. Then
[tex]y(t) = 300(4)^t[/tex]
(c) How many bacteria are there after 40 minutes?
40 minutes is 40/30 = 1.33 periods of half hour. So this is y(1.33).
[tex]y(1.33) = 300*(2)^{1.33} = 754[/tex]
