Answer:
the ratio used was 1:19
Step-by-step explanation:
let a be the action figure version
let r be the real iron man
let's list out the important things.
a = 4''
r = 6'4''
one foot has 12 inches
convert r into inches:
6 × 12 = 72 (6 feet in r)
r = 76'' (72 + 4)
r = 76''
a = 4''
ratio is 4:76
simplify
4:76
2:38
1:19
the ratio they used is 1:19

Carla roller skates 3 miles each weekday and 5 miles each day on the weekend.Which expression represents how many miles she roller skates in w weeks?
Answer:
23w
Step-by-step explanation:
For 6days, She skates 3 * 6 = 18 miles
on weekend she skates 5 miles
Thus, In one week, she skates 23miles
In w week, she skates: 23w
in this exercise we have to know conversion, so it will be necessary to correct the space in time, which will represent in weeks:
28 weeks
So first, we have to calculate the total distance traveled in every day, like this:
[tex]days: 6*3=18\\weekends: 5*2=10\\total:18+10=28[/tex]

find the circumference of a circle with a radius of 9.8 in. (urgent)
Answer: 61.58
Step-by-step explanation:
C = 2 π r = 2 · π · 9.8
π = pi
radius times pi (3.14) times 2 (because two radius makes the diameter)
9.8 times 3.14 times 2 = 61.57522in
Now we round.. 61.58

1b) What is the slope of the equation?
1c) What is the y-intercept of the equation?
Answer:
[tex] - 2x + 5y = 20 \\ 5y = 2x + 20 \\ y = \frac{2}{5} x + 4 \\ slope = \frac{2}{5} \\ y - intercept = 4[/tex]

Answer:
x = 4
Step-by-step explanation:
1. Write the equation
3/4x = 2x - 5
2. Get the variables on the same side
Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!
-1.25x = -5
3. Divide both sides by -1.25
x = 4

I need to determine which ones are parallel, perpendicular, or neither.
Please help
Answer:
Parallel:
y=3x-7 y=-4x-1 y=1/3x +9 -9x+12y=24 y=x-3
y=3x+1 8x+2y=14 x-3y =3 y=3/4x -5 x-y=8
Perpendicular:
y=-2/5x +3 y=-1/4x 2x+7y=28 y=-5x+1 x+y=7 5x-10y=-20
y=2/5x +8 y=4x-5 7x-2y=4 x-5y=30 x-y=9 y=-2x+6
10x+8y=16
5y=4x-15
Neither:
3x+2y=8 4x+9=18 y=5/3x +7
2x+3y=-12 y=4x+9 6x-10y=10

Step-by-step explanation:
on the x it goes from a 3 3/5 to 5 2/5 then drops down to ten.
we already know this is wrong because linear means going straight and proportional when displayed on a graph instead of having zigzag and sharko lines

g(x)=3x+2 and h(x)=ax+B
where a and b are constants
h(4)=22
g^-1(14)=h(1)
find the value of a and the value of b
Answer:
a=6
b=-2
Step-by-step explanation:
You can use the hint provided on the mathswatch question page, I've attached it below
step 1
h(4) = ax+b = (ax4)+b = 4a+b
it is given in the question that h(4)=22, therefore 4a+b=22
step 2
work out the equation for inverse g
g^-1(x) = [tex]\frac{x-2}{3}[/tex]
step 3
input 14 into the equation in place of x to find g^-1(x)
[tex]\frac{x-2}{3} =\frac{14-2}{3} =\frac{12}{3} =4[/tex]
so, g(x)^-1=4
step 4
find h(1):
h(1) = (ax1)+b = a+b
so, h(1)=a+b
step 5
a+b=4 (as it is given in the question that g^-1(14) is equal to h(1))
step 6
Now you have two simultaneous equations:
4a+b=22
a+b=4
then, solve for a:
4a+b=22
- a+b=4
3a=18
a=6
then, input answer for a into either equation (I've gone with the a+b=4 equation):
6+b=4
-6 - 6
b=-2

What is the surface area of cereal box whose length , breath, and height are 20cm , 8cm,30cm ,also find its volume
Answer:
V = 4800 cm^3
SA = 2000 cm^2
Step-by-step explanation:
V = l x w x h
V = 20 x 8 x 30
V = 4800 cm^3
20 x 8 x 2 = 320 cm^2
20 x 30 x 2 = 1200 cm^2
8 x 30 x 2 = 480 cm^2
320 + 1200 + 480 = 2000 cm^2

Step-by-step explanation:
This is an overlapping triangles problem. Try drawing them separately, essentially pulling them apart. Mark side XY and XZ as congruent (given).
Angle X is shared by the two triangles, so angle X in triangle XAZ is congruent to angle A in triangle XBY.

multiply 65 by 80 then divide by 100, you get 52, so subtract 65 from 52 you get 13
The product of all digits of positive integer M is 105. How many such Ms are there with distinct digits?
Answer:
6
Step-by-step explanation:
105 is a composite number (not prime). If you decompose 105 into its prime factors (see attached image), you get 105 = 3 x 5 x 7. This means that the product 105 can only be written this way; any other way, for example 15 x 7 would not use numbers that are single digits.
The question boils down to how many ways the digits 3, 5, 7 can be arranged, using each digit exactly once.
That's a permutation problem, and it can be answered easily by thinking this way: given the digits 3, 5, 7, there are 3 choices for the first digit, then 2 for the second digit (for EACH of the first choices), then only 1 choice for the final digit.
3 x 2 x 1 = 6 ways that 3, 5, 7 can be arranged to make a 3-digit number. Here they are:
357, 375, 537, 573, 735, 753

If b is a perfect square, which represents the solutions to the equation?
HELP PLEASE
Answer:
[tex]\{\sqrt b, -\sqrt b\}[/tex]
Step-by-step explanation:
Given
[tex]a^2 - b = 0[/tex]
Required
Determine the solution
Since b is a perfect square, the equation can be expressed as:
[tex]a^2 - (\sqrt b)^2 = 0[/tex]
Apply difference of two squares:
[tex](a - \sqrt b)(a + \sqrt b) = 0[/tex]
Split:
[tex](a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0[/tex]
Remove brackets:
[tex]a - \sqrt b= 0 \ or\ a + \sqrt b = 0[/tex]
Make a the subject in both equations
[tex]a =\sqrt b \ or\ a =-\sqrt b[/tex]
The solution can be represented as:
[tex]\{\sqrt b, -\sqrt b\}[/tex]
You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.
