Here are two similar solid toys.
A
B
The ratio surface area of toy A : surface area of toy B is 7:9
The volume of toy B is 20 cm
I
Work out the volume of toy A.
Give your answer correct to 3 significant figures.
Answers
Answer:
13.7
Step-by-step explanation:
7*k²=9
k²=9/7
k=√9/7
k=1.133893419
20/1.133893419³=13.7
The volume of toy A will be equal to 13.7 cubic centimetres.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio surface area of toy A: to the surface area of toy B is 7:9. The volume of toy B is 20 cm
The computation of the volume of toy A is shown below:
7 × k²=9
k²= 9 ÷ 7
k=√(9 ÷ 7)
k = 1.133893419
Now
The volume of toy A = 20 ÷ 1.133893419³
The volume of toy A = 13.7 cubic centimetres
Therefore, the volume of toy A will be equal to 13.7 cubic centimetres.
The missing figure is attached with the answer below.

Given: c(x) = 2x – 6
Find c(x) = 18
Answers
-2x = -6 -18
-6 -18 is = -24 (you add negative numbers together)
-2x = -24 (divide both numbers by -2)
X = 12
Answer:
18
X = ---- , y = 12
c
Step-by-step explanation:
Solve for x, y
X = 18
__
c
Y = 12, c ≠ 0
Consider the first equation. Subtract 2y from both sides.
cx - 2y = -6
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
cx = 18, cx - 2y = -6
Pick one of the two equations which is more simple to solve for x by isolating x on the left hand side of the equal sign.
cx = 18
Divide both sides by c.
18
X = __
c
Substitute 18/c for x in the other equation,
c x - 2y = - 6.
18
c x ( ---- ) - 2y = - 6
c
18
Multiply c times ----
c
18 - 2y = - 24
Subtract 18 from both sides of the equation.
- 2y = - 24
Divide both sides by -2.
y = 12
The system is now solved.

X = ---- , y = 12

A factory needs to produce 1,800 jars of peanut butter on a certain day.
They start production at 8:30 A.M. By 10:30 A.M., they have produced 600 jars of peanut butter. At what time will they complete the total number of jars that they need to produce?
Answers
Answer:
2:30 am
Step-by-step explanation:
There is a 2 hour gap in between 8:30 and 10:30 and since they only made 600 jars throughout those 2 hrs you can divide 600 by 2 so you can fins out how many jars they make every hr.
Or you can multiply 600 and 2 to find out how much they make within the next 2 hrs.
600 * 2 = 1200
1200 jars were made at 12:30
1200 * 2 = 1800
1800 jars were made at 2:30
There are two hours between 8:30 A.M. and 10:30 A.M. If they make 600 jars of peanut butter per two hours, then they will make 300 jars per hour. 1800 divided by 6 is 300, so they need six hours to make 1800 jars of peanut butter. So, if they begin production at 8:30 A.M., the factory will have produced 1800 at 4:30 P.M.

Final amount V
using the relation
[tex]V = Pe^{rt}[/tex]
Substituting we have
[tex]V = 7420e^{0.059*20}\\\\V=7420e^{1.18}\\\\V=7420*3.2543\\\\V=24147.456[/tex]

Find the value of x.
Answers
Answer:
x = 19
Step-by-step explanation:
The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.
3x + 5 + 7x - 15 = 180
~Combine like terms
10x - 10 = 180
~Add 10 to both sides
10x = 190
~Divide 10 to both sides
x = 19
