Triangle weighs 3 grams Circle weighs 6 grams. Write an equation to represent each hanger. Let x represent the pentagon.
Answers
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g

Translate the figure using the rule (x + 6, y + 1) and then reflect over the x- axis.

Answers
Step-by-step explanation:
well, the translation (x+6, y+1) creates the following points :
D goes from (-4,-4) to (2,-3)
E goes from (-4,-2) to (2,-1)
A good from (-1,-4) to (5,-3)
the reflection over the x-axis leaves then the x values unchanged, and negative y values turn positive (or vice versa, if we had a case here).
so,
D' = (2,3)
E' = (2,1)
A' = (5,3)
-1 1/2 _ -1 3/4 which one is greater or less, or equal?
Answers
Answer:
The answer is -1 1/2 is less than -1 3/4
Step-by-step explanation:
I look at it more as numbers, so for example 1/2 can be simplified into 50, and 3/4 is 75/ 75 would be greater if it was positive. But, with there being a negative 1 in front of the answer, the lowest number closest to 0 is better. :D
Answer: -1 1/2 is greater
Step-by-step explanation:
-1 1/2 is closer to zero and that makes it larger because they are negative numbers.

A) [tex]x=42\sin32^\circ[/tex]
Step-by-step explanation:
With respect to our angle, the side opposite to it is [tex]x[/tex], and the hypotenuse is [tex]42[/tex], so the trig ratio we need to use here is sine as [tex]\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]. Hence, if we rearrange the equation so that we solve for the opposite side [tex]x[/tex], then we'll have [tex](\text{hypotenuse})(\sin\theta)=\text{opposite}\rightarrow42\sin32^\circ=x[/tex] as the correct equation.

What is the sales tax on a refrigerator priced $1269, if the sales tax rate is 6.7%?
Answers
Answer:
sales tax: $85.023
Explanation:
Original or actual price is always of 100%
Solving:
100% = $1269
Find the unit percent :
1% = $(1269/100) = $12.69
Find the sales tax :
$12.69 × 6.7 = $85.023
Barb pulled the plug in her bathtub and it started to drain. The amount of water in the bathtub as it drains is represented by the equation L = -5t - 8t + 120, where L represents the number of liters of water in the bathtub and t represents the amount of time, in minutes, since the plug was pulled. How many liters of water were in the bathtub when Barb pulled the plug? Show your reasoning. Determine, to the nearest tenth of a minute, the amount of time it takes for all the water in the bathtub to drain.
Answers
The bathtub had 120 L of water before Barb pulled the plug.
It will take about 9.23 minutes for the water to drain out.
Given equation: L = -5t - 8t + 120
Simplified: L = -13t + 120
Notice how it's written in slope-intercept form (y = mx+b)
The y-intercept (L) is 120. So the coordinates for L = (0 , 120)
The coordinates mean that before the water in the bathtub began draining out, it initially had 120 Liters of water.
Now that we know how many liters there were before, the new equation would look like this: L = -13t --> 120 = -13t
Solving the equation, we get that t = -9.23 minutes
Since time can't be negative, we'll just say that it will take 9.23 minutes to drain out all the water.

Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45

Solve for the missing variables. (Geometry)
Answers
Step-by-step explanation:
we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.
in other words
h² = p×q
h = height
p, q are the 2 segments of the Hypotenuse.
so, in our case we have
100 = x(x + 21) = x² + 21x
that gives us the following quadratic equation
x² + 21x - 100 = 0
the general solution to a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 21
c = -100
so,
x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =
= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =
= (-21 ± 29)/2
x1 = (-21 + 29)/2 = 8/2 = 4
x2 = (-21 - 29)/2 = -50/2 = -25
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).
