if the original quantity is 12 and the new quantity is 15, what is the percentage increase
Answer:
25%
Step-by-step explanation:
Given data
original quantity =12
new quantity =15
% increase= new-original/original *100
% increase= 15-12/12 *100
% increase= 3/12 *100
% increase=0.25 *100
% increase=25%
hence the increase is 25%
Which equation could be used to solve for the length of side c, given a = 5, b = 12, and C = 72°?
Answer:
i had this question before
Step-by-step explanation:
c^2=a^2+b^2-2abcos(c)
c=sqrt(a^2+b^2-2abcos(c))
c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))
c=sqrt(25+144-120cos(72))
c=sqrt(169-120cos(72))
c=sqrt(169-37.08)
c=sqrt(131.92)
c=11.49
Hire charges for a mini bus consist of Ex fixed charge + y pence for each mile of the journey A hire for 20 miles costs £25 A hire for 30 miles costs £30. How much would a hire for 50 miles cost?
Answer:
the cost of hiring 50 miles is £55
Step-by-step explanation:
The computation of cost for hiring 50 miles is shown below:
= 20 miles cost + 30 miles cost
= £25 + £30
= £55
Hence, the cost of hiring 50 miles is £55
The same would be considered and relevant too

Solve system by elimination
9x + 3y = 24
10x - 2y = 0
Answer:
(1, 5 )
Step-by-step explanation:
Given the 2 equations
9x + 3y = 24 → (1)
10x - 2y = 0 → (2)
Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term
18x + 6y = 48 → (3)
30x - 6y = 0 → (4)
Add (3) and (4) term by term to eliminate y
48x + 0 = 48
48x = 48 ( divide both sides by 48 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (1)
9(1) + 3y = 24
9 + 3y = 24 ( subtract 9 from both sides )
3y = 15 ( divide both sides by 3 )
y = 5
solution is (1, 5 )

Solve the equation -10(d + 1) = -14.
d=
?
Answer:
d = 0.4
Step-by-step explanation:
Given
- 10(d + 1) = - 14 (divide both sides by - 10 )
d + 1 = 1.4 ( subtract 1 from both sides )
d = 0.4

Juan made 3 identical necklaces each having beads and a pendent the total cost of the beads and pendent for all 3 necklaces was $19.20. If the beads cost $2.80 for each necklace, how much did each pendant cost?
Help I gave 30 points
Answer:
Step-by-step explanation:
2.80 x 3 = 8.40 so 19.20-8.40=10.8 then 10.80/3= 3.60
what is the equation of the line that passes through the point(4,12) and has a y-intercept of -2?
Answer:
y=3.5x-2
Step-by-step explanation:
y=mx+c
12=m×4-2
add 2 on both sides
14=m×4
divide by 4 on both sides
3.5=m
y=3.5x-2

4) Part A: A biologist counted the number of two types of salmon (Chanook and Steelhead) at a dam. He used the table below to record the number of salmon on different days. On day 5, the biologist counted 16 Chinook. If the ratio of Chinook to Steelhead remained the same as on the previous four days, how many Steelhead should the biologist expect to count on day 5? Record your answer below. *
Captionless Image
Answer:
The answer is 40
Step-by-step explanation:
He expects to count #####################################
There are 12 Steelhead should the biologist expect to count on day 5.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The ratio of Chinook to Steelhead on the first four days is 4:10.
If this ratio remained the same on day 5, then we can expect the biologist to count of the salmon as Chinook.
On day 5, the biologist counted 16 Chinook,
Let x Steelhead would be the biologist expected to count on day 5.
As per the given question, the required solution would be as:
4/10 = 16/x
x = 16 × 10 / 4
x = 160/4
x = 40
Hence, there should be 40 Steelhead.

Answer:
217.98 is greater.
Step-by-step explanation:
Think about this way. Which is the larger number, 217 or 21? 217, of course. The decimal point only adds a small fraction of a number to the whole, so it doesn't affect the value that much.

Find the missing side Lengths.
Answer:
5.23606798
Step-by-step explanation:
Find the inverse of each function:
g(x)=[tex]\frac{-5x+5}{2}[/tex]
A. g^{-1}[/tex](x)=[tex]\frac{5-2x}{5}[/tex]
B. g^{-1}[/tex](x)=[tex]4+\frac{4}{3}x[/tex]
C. g^{-1}[/tex](x)=[tex]\frac{10-x}{2}[/tex]
D. g^{-1}[/tex](x)=[tex]-4+\frac{1}{3}x[/tex]
Answer:
Step-by-step explanation:
Replace g(x) with y, then switch the x and y variables:
[tex]x=\frac{-5y+5}{2}[/tex]
Solve for the new y value, multiply by 2:
[tex]2x=-5y+5[/tex]
Subtract 5 on both sides:
[tex]2x-5=-5y[/tex]
Divide by -5 on both sides:
[tex]-\frac{2x-5}{5} =y[/tex]
Distribute the negative sign and rearrange:
[tex]\frac{-2x+5}{5} =\frac{5-2x}{5} =g^-^1(x)[/tex]
Answer:
A. g⁻¹(x) = (5 - 2x)/5Step-by-step explanation:
Given functiong(x) = (-5x + 5)/2Find the inverse of g(x)SolutionSubstitute x with y and g(x) with x and then solve for y:
x = (-5y + 5) /22x = -5y + 55y = -2x + 5y = (-2x + 5)/5y = (5 - 2x)/5Replace y with g⁻¹(x)
g⁻¹(x) = (5 - 2x)/5Correct choice is A
