The sum of a number x and 2,496 is 17,344. What is the value of x
Answer:
x = 14,838
Step-by-step explanation:
equation is
x + 2,496 = 17,344
x = 17,344-2,496
x = 14,838

2x + 5y = 32
Answer:
x = 16 -5/2y
Step-by-step explanation:
2x + 5y = 32
2x = 32 -5y
/2 /2
x = 16 -5/2y
Answer:
y= 2x/5 + 6.4
Step-by-step explanation:
divide both sides by 2x
5y = 2x + 32
divide both sides by 5
y = 2x/5 + 6.4
follow same step to solve for x except first divide by 5y instead of 2x
Raymond's bake shop sold 26 1/2 cupcakes on Saturday on Friday the bake shop sold 19 3/4 dozen cupcakes what is the approximate percent increase in cupcake sales from Friday to Saturday
Answer: 34.18%
Step-by-step explanation:
Given: On Saturday, Number of cupcakes sold = [tex]26\dfrac12[/tex] dozens
= [tex]\dfrac{53}{2}[/tex] dozens
[tex]=\dfrac{53}{2}\times12[/tex] [ 1 dozen = 12 items]
[tex]=53\times6\\\\=318[/tex]
On Friday, Number of cupcakes sold = [tex]19\dfrac34[/tex] dozens
= [tex]\dfrac{79}{4}[/tex] dozens
[tex]=\dfrac{79}{4}\times12[/tex] [ 1 dozen = 12 items]
[tex]=79\times3\\\\=237[/tex]
Increase in cupcakes = 318-237=81
Percent increase in cupcakes sales from Friday to Saturday = [tex]\dfrac{81}{237}\times100[/tex]
= 34.18% (approx)
The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%

if zaeirr has 10 dogs and lamarr has 2 dogs how many more dogs does zaeirr have than lamarr?
Answer: 8
Step-by-step explanation:
For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.
10 subtracted by 2 is equal to the number 8.
The answer to our question is 8.
A museum has an aquarium in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high. What is the volume, rounded to the nearest cubic meter, of the aquarium?
Answer: The volume of the aquarium = 790 cubic meters
Step-by-step explanation:
Volume of rectangular prism = length x width x height
Given: An aquarium is in the shape of a right rectangular prism that is 22.9m long, 7.5m wide and 4.6m high.
Volume = [tex]22.9\times7.5\times4.6[/tex]
i.e. Volume = 790.05 cubic meters
i.e. Volume ≈ 790 cubic meters (rounded to the nearest cubic meter)
Hence, the volume of the aquarium = 790 cubic meters (approx)
DOMAIN AND RANGE PLS HELP
Answer:
44
Step-by-step explanation:
The range is possible y-values so we just plug in all the domains to find the range
When x=-4, y=44
When x=0, y=0
When x=1, y=-1
When x=2, y=2
When x=3, y=9
When at the function at x=4, it is the largest so y=46

Find the value of X express each answer as a decimal rounded to the nearest tenth.
Answer:
x = 15.6
Step-by-step explanation:
use the pythagorean theorem:
a² + b² = c²
a = 9
b = x
c = 18
(9)² + x² = (18)²
81 + x² = 324 subtract 81 from both sides
x² = 243 take the square root of both sides
x = √243
x = 15.6
will give brainliest to right answer please help!! 15 points -A sample of a radioactive isotope had an initial mass of 370 mg
in the year 2000 and decays exponentially over time. A
measurement in the year 2008 found that the sample's mass
had decayed to 110 mg. What would be the expected mass of the
sample in the year 2017, to the nearest whole number?
Answer:
78 mg
Step-by-step explanation:
370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)
260 mg ÷ 8 years = 32.5 mg decayed per year
32.5 × 9 years (years between 2008 and 2017) = 292.5 mg
370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg
the expected mass of the sample in the year 2017, to the nearest whole number is 0.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
Given, Initial mass(y₀) = 370 mg.
After 8 years (t = 8) the mass decayed to y₈ = 110 mg.
∴ 110 = 370.e^(-8k).
e^(-8k) = 3.36.
lne^(-8k). = ln(3.36).
- 8k = 1.28.
k = - 1.28/8.
k = - 1.6.
Now expected mass of the sample in 2017 which in 9 years from 2008 will be,
y = 110.e^(-1.6×9).
y = 110.e^(-14.4).
y = 110/e^(14.4).
y = (110/1794074.78).
y = 6.13^(-5) mg.
y = 0.0000613 mg.
