X/12 = 3/9 what does x equal and how did you get the answer
Answers
Answer:
4
Step-by-step explanation:
You can cross multiply.
first i would simplify x/12=3/9 to x/12=1/3
so then it would be equal to x*3=1*12
then i would simplify it to 3x=12
then you solve for x and i would get 4
Answer:
x = 4
Step-by-step explanation:
\(\frac{x}{12} =\frac{3}{9} \\\)
Simplify \(\frac{3}{9} = \frac{1}{3} \\\)
What is a third of 12?

1. −2x + 6 = -16
2. -10 + 5x = -45
Can you help me?
Answers
Answer:
for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2
getting -2x/-2=-22/-2 then you simplify that and get x=11
and for the second one x=-7. first, you have to add 10 to both sides
(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

the ratio of males to females at a camp is 5 to 4. If there are 40 males at the camp, how many females are there?
Answers
Answer:
5 males : 4 females
40 males : X females
5/40 =4/X
(cross multiplication)
5x = 4*40
5x = 160
(divide both sides by 5)
X = 32
therefore, there are 32 females at the camp
Jaha has designed a rocket. She determines the initial velocity of her rocket is 36 meters per second. She uses the function h(t) = - 9.8t ^ 2 + 36t to find the height, h(t) based on time, t, in seconds. Jana wants to know approximately when her rocket will be at the following heights:
24 Meters
36 Meters
Answers
To find when the rocket will be at a certain height, we can set the equation for height, h(t), equal to the given height and solve for t.
For 24 meters:
-9.8t^2 + 36t = 24
-9.8t^2 + 36t - 24 = 0
We can solve for t using the quadratic formula:
t = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = -9.8, b = 36, and c = -24. Plugging in these values, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-24))) / 2(-9.8)
t ≈ 1.87 seconds or t ≈ 3.14 seconds
So the rocket will be at a height of 24 meters approximately 1.87 seconds after launch and again approximately 3.14 seconds after launch.
For 36 meters:
-9.8t^2 + 36t = 36
-9.8t^2 + 36t - 36 = 0
Using the quadratic formula again, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-36))) / 2(-9.8)
t ≈ 1.16 seconds or t ≈ 3.66 seconds
So the rocket will be at a height of 36 meters approximately 1.16 seconds after launch and again approximately 3.66 seconds after launch.
The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.
2.17 inches
10.68 inches
21.35 inches
36.29 inches
Answers
d = 6.8 in
π (in this problem) = 3.14
Keep the formula in mind: C = 2πr
We have d, but no r. However, we know that r = 1/2d, or the radius is half the diameter.
Then again, it’s 2πr, or 2rπ, ORRRRR dπ.
So 6.8(3.14) = 21.352.
The choices only go in 2 decimal places so round.
Your answer is the 3rd choice: 21.35 in.
The required distance around the hat is approximately 21.35 inches. Option C is correct.
What is the circumference of the circle?To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.
Here,
The distance around a circle is given by the formula circumference = π × diameter.
Substituting the given values, we get:
circumference = 3.14 × 6.8
circumference = 21.352
Rounding to the nearest hundredth, we get:
circumference ≈ 21.35 inches
Therefore, the distance around the hat is approximately 21.35 inches.

What is the surface area of the figure? PLEASE HELP ASAP !! 7th grade Geometry
Answers
Answer:
SA = 578ft²
Step-by-step explanation:
First, we have to know the formula of finding the surface area of a rectangular prism.
Formula: 2(wl + hl + hw)
w = width l = length h = height
Next, we separate the composite figure into two rectangular prisms.
Since we have all measurements, let's use that to find the SA.
The first shape (to the left)
SA = 2(wl + hl + hw)
SA = 2(4 x 9 + 9 x 9 + 9 x 4)
SA = 2(36 + 81 + 36)
SA = 2(153)
SA = 306
Then, we do the other shape(to the right)
We know the measurement of length = 4 because it is the same measurement as the width
SA = 2(wl + hl + hw)
SA = 2(4 x 4 + 15 x 4 + 15 x 4)
SA = 2(16 + 60 + 60)
SA = 2(136)
SA = 272
Lastly, we add those two
306 + 272 = 578
Therefore, SA = 578ft²

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.
