Answer:
The other sides are 6cm and 8cm
Step-by-step explanation:
Let the other 2 sides be x and y.
Using herons formula, we have an equation
24=sqrt(12*2*(12-x)*(12-y))
Since the perimeter is given, we have x+y=24-10=14. Solving it we have x=6,8 and y=8,6.
What is the scale factor?
Answer: B
Step-by-step explanation:
You can see that the length of the sides from abc are factored by 1/3 to get the length of xyz. Therefore, the scale factor is 1/3.
What is the value of g(f(x)) f(x)=2x^2+3 g(x)=x-4
Answer:
2x^2 -1
Step-by-step explanation:
f(x)=2x^2+3
g(x)=x-4
g(f(x))
Replace x in g(x) with the function f(x)
g(f(x)) = 2x^2+3 -4
Combine like terms
=2x^2 -1

A train station is between the towns Antville and Bugville. The station is four times as far from Bugville as it is from Antville. If the distance from Antville to Bugville is 95 km, how far is it from Antville to the station?
Answer:
237.5 or 238
Step-by-step explanation:
95km=10
95km×10=950
950÷4= 237.5cm
approximately 238
a colleague needs to move a 500 pound object that's on a lever. the fulcrum is 6 inches from the object. If your colleague weighs 180 pounds how far will your colleague need to be from the fulcrum to move the object? Use the formula B = (P x A) ÷ W, and round your answer to two decimal places.
Answer:
Step-by-step explanation:
The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:
[tex]\tau_{man}>\tau_{box}[/tex] and
[tex]180r>500(.1524)[/tex] That decimal is 6 inches in terms of meters.
180r > 76.2 so
r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.
Which of the following choices is a linear function?
O f(x) = x2 – 3x+ 2
O f(x) = 3x3 – 3x + 2
O f(x) = -3x + 2
Answer:
f (x) = x2 - 3x + 2
Step-by-step explanation:
Answer:
f(x)=-3x+2
Step-by-step explanation:
The first one is a quadtratic function because it is in quadtratic form.
The second one is also not linear because it looks like a squiggly line. Sorry I forgot what they are called but I know it is not linear.
That leaves the last one is is linear and should be going down because there is a negative in front of the coefficient. It also has so exponent to prove why it is linear even further.

We use the formula V = πr2h to find the volume of a cylinder. Make h the subject of the formula.
Answer:
V / ( pi r^2) = h
Step-by-step explanation:
V = pi r^2 h
Divide each side by pi r^2
V / ( pi r^2) = pi r^2 h / pi r^2
V / ( pi r^2) = h
A certain shampoo is available in two sizes. A 14.2 ounce bottle costs $3.98. A 33.9 ounce bottle costs $9.98. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent. Thank you!
Answer:
A 14.2 ounce bottle costs $3.98 is the better buy
Step-by-step explanation:
Find the price per ounce for each
A 14.2 ounce bottle costs $3.98
3.98 /14.2 =.28028169 = .28 per ounce
A 33.9 ounce bottle costs $9.98
9.98/33.9 =.29439528 = .29 per ounce
In right triangle ABC
a.30°
b.45°
c.60°
d.75°
Answer:
c
Step-by-step explanation:
30°+90°+x=180° (the sum of interior angle of a triangle is 180°)
120°+x=180°
x=180°-120°
x=60°

Twice a number decreased by 39 is five times the sum of the
number and 2 times the number. Find the number.
Answer: x=-3
Step-by-step explanation:
2(x)-39=5(x+2x)
2x-39=5(3x)
2x-39=15x
-39=13x
-39/13=-3

12 a) Find the sum and difference between the place value and face value of 5 in the number 35086941 .
Answer: Sum = 5000005, Difference = 4999995
Explanation:
Number = 35086941
Place value = 5000000
Face value = 5
Sum = 5000000 + 5
= 5000005
Difference = 5000000 - 5
= 4999995

An ice-making machine needs to be switched on
for 10 minutes before the production of ice begins.
The mass, in tờnnes, of ice produced is directly
proportional to the number of hours of production.
Given that 20 tonnes ofâce are produced when the
machine runs for half an hour, find the mass of ice
manufactured when the machine runs for
1.75 hours
Since the question explicitly stated that ice production is proportional to time, we're going to have to use proportion fractions. Remember to convert hours into minutes as well.

Step-by-step explanation:
Consider the expression
-4b + 8c + 12 - 8b - 2c + 6.
Part A
Factor the simplified expression using the GCF.
Answer:
-12 b + 6 c + 18
Step-by-step explanation:
-4 b + 8 c + 12 - 8 b - 2 c + 6
After simplification, the correct value is,
⇒ 6 (- 2b + c + 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We haver to given that;
The expression is,
⇒ -4b + 8c + 12 - 8b - 2c + 6.
Now, We can simplify by combine like terms as;
⇒ -4b + 8c + 12 - 8b - 2c + 6.
⇒ - 12b + 6c + 18
And, GCD of 12, 6, 18 = 6
Hence, Take 6 as common as;
⇒ - 12b + 6c + 18
⇒ - 2×6b + 6c + 3×6
⇒ 6 (- 2b + c + 3)
Therefore, The solution of the expression is,
⇒ 6 (- 2b + c + 3)
