What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.

The equation d = is can be used to calculate the density, d, of an object with mass, m, and volume, V. Which is an
equivalent equation solved for V?
Answer:
V = m/d
Step-by-step explanation:
d = m/V, m = mass and V = volume
We want to solve for V
Multiply each side by V
dV = m/V *V
dV = m
Divide each side by d
dV / d = m/d
V = m/d

Answer:
the median for A is 26 and the mean for B is 24
Step-by-step explanation:
since 24 and 28 are both in the middle we need to find the mean of 24 and 28 to find A's median.
18+19+21+25+29+32=144
144 divided by the # of terms 6 gives our mean 24 for B.

Answer:
Option A.
Step-by-step explanation:
The given ratios are 2:3, 3:4, 5:6, 1:5.
We need to arrange these ratios in descending order.
Fraction form of given ratios are
[tex]\dfrac{2}{3},\dfrac{3}{4},\dfrac{5}{6},\dfrac{1}{5}[/tex]
First find LCM of denominators.
[tex]LCM(3,4,6,5)=60[/tex]
Now, make denominator common, i.e., 60.
[tex]\dfrac{2\times 20}{3\times 20},\dfrac{3\times 15}{4\times 15},\dfrac{5\times 10}{6\times 10},\dfrac{1\times 12}{5\times 12}[/tex]
[tex]\dfrac{40}{60},\dfrac{45}{60},\dfrac{50}{60},\dfrac{12}{50}[/tex]
Now, arrange numerator in descending order.
[tex]50>45>40>12[/tex]
[tex]\Rightarrow \dfrac{50}{60}>\dfrac{45}{60}>\dfrac{40}{60}>\dfrac{12}{50}[/tex]
[tex]\Rightarrow \dfrac{5}{6}>\dfrac{3}{4}>\dfrac{2}{3}>\dfrac{1}{5}[/tex]
[tex]\Rightarrow 5:6>3:4>2:3>1:5[/tex]
Therefore, the correct option is A.

Kite K N M L is shown. Sides L K and K N are congruent. The length of L K is 2 y + 5 and the length of K N is y + 10. Sides N M and M L are congruent. The length of N M is 2 x + 6 and the length of M L is 3 x minus 1. What are the lengths of sides KN and NM of the kite? KN = units NM = units
Answer:
kn=15
nm=20
Step-by-step explanation:
The lengths of sides KN and NM of the kite
KN = 15 units
NM = 20 units
What is kite's shape?A kite is a quadrilateral with four sides that may be divided into two neighboring pairs of equal length sides. A parallelogram, on the other hand, has two sets of equal-length sides, but they are opposed to one another as opposed to being adjacent.
Given:
KLMN is a kite.
According to the given kite,
KN = KL........ (1)
and LM = NM........ (2)
From equation (1)
y + 10 = 2y + 5
y = 5.
Now,
3x -1 = 2x + 6
x = 7
We get,
LM = MN = 20
KN = 15 units
NM = 20 units

THANKS FOR GIVING ME THE OPPORTUNITY TO ANSWER YOUR QUESTION.
The circumference of the circle having a diameter of 5 ft will be 15.7 ft.
What is circumference?
The easiest way to find the perimeter for any shape is to add up the lengths of all the sides, but a circle only has one side, so that isn't possible. If you don't know its circumference, you also don't know the length of that side.
Fortunately, we can use a formula that uses other properties of a circle to find its circumference. In fact, there are two different formulas for circumference we can use and they look like this:
C = 2πr
Here the diameter of the giver circle is 5 ft so the radii will be 2.5 ft
By putting the value of radius in the formula we get
[tex]C=2\pi r[/tex]
[tex]C=2\pi \times 2.5=15.7\ ft[/tex]
Hence the circumference of the circle having a diameter of 5 ft will be 15.7 ft.

Answer:
∠DHGStep-by-step explanation:
Same side interior angles refers to the pair of angles which are inside the two "parallel" lines and at the same side of the transversal line.
Notice that angles BGH and DHG are same side interior angles. Similarly, angles AGH and CHG are also same side interior angles.
Therefore, the right answer is ∠DHG.
