what percent of 12 is 3.3?
Answer:
27.5%
Step-by-step explanation:
Hi!
To do this problem, we have to set up a percent proportion:
[tex]\frac{3.3\\}{x}[/tex] = [tex]\frac{12}{100}[/tex]
In this problem, the denominators are the percent values and the numerators are the numerical value.
x = [tex]\frac{3.3*100}{12}[/tex]
x = [tex]\frac{330}{12}[/tex]
x = 27.5%

hope this helpsA licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves, what length of licorice will each student get?
Answer:
1.4 Inches Each
Step-by-step explanation:
This problem is fairly simple. Just divide 7 by 5 and put the correct units(inches) with the answer.
length of licorice each student will get is 1.875 inches.
What is simplification?A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.
Given, A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves.
Since every 5th grader is sharing the rope equally.
Thus everyone will get = 7/4
Every 5th grader will get = 1.875 inches
Therefore, every 5th grader will get 1.875 inches length of licorice.

The fountain is made up of two semicircles and one quarter circle. Find the perimeter and area of the fountain.
Answer:
628ft²
Step-by-step explanation:
From the diagram, we are given the following
diameter of the semicircles
2semi circles = 1 circle
Area of 2semicircles = πd²/4
Area of 2semicircles = 3.14(20)²/4
Area of 2semicircles = 3.14*400/4
Area of 2semicircles = 3.14*100
Area of 2semicircles = 314ft²
Area of the quarter circle = πd²/4 * 1/4
Area of the quarter circle = πd²/16
d = 2r
d = 2*20
d = 40ft
Area of the quarter circle = 3.14(40)²/16
Area of the quarter circle = 3.14*1600/16
Area of the quarter circle = 3.14*100
Area of the quarter circle = 314ft²
Area of the fountain = 314ft²+314ft²
Area of the fountain = 628ft²

Answer:
5x-10
Step-by-step explanation:
3x-4+2x-6
group like terms
3x+2x -4--6
5x-10
The expressions that are equivalent to 3x - 4 + 2x - 6 are:
5x - 2 - 6
5x - 16
To determine which expressions are equivalent to 3x - 4 + 2x - 6, we can simplify the given expression:
3x - 4 + 2x - 6
Combining like terms, we have:
(3x + 2x) + (-4 - 6)
Simplifying further:
5x - 10
Now, we can compare this simplified expression to the provided options:
a) 3x + 2x - 10
b) 5x - 2 - 6
c) 5x - 16
d) 6x - 10
By comparing the simplified expression 5x - 10 to the options, we find that options b) (5x - 2 - 6) and c) (5x - 16) are equivalent expressions.

If the toy store sold 5 dozen of the latest action figure, how many accessories did the store sell? Enter your answer in the box.
______ accessories
Answer:
Turbo jetpack = 6(d + 7)
Xray vision glasses = 2d - 5
Invisible shield = 10d + 1
18d + 38 ;
128 dozen accessories
Step-by-step explanation:
Let the number of boxes sold = d
Turbo jetpack = 6(d + 7)
Xray vision glasses = 2d - 5
Invisible shield = 10d + 1
Combined number of accessories sold :
6(d + 7) + (2d - 5) + (10d + 1)
6d + 42 + 2d - 5 + 10d + 1
18d + 38
If 5 dozens are sold
d = 5
Number of accessories sold :
18(5) + 38
90 + 38 = 128 dozens accessories
what is the mass of an object that has a volume of 34 cm^4 and a densityof 6 g/cm^3?
Answer:
Mass = density * volume
Mass = 6 g/cm^3 / 34 cm^3
Mass = 0.1764705882 grams
Step-by-step explanation:
Answer:
204 g
Step-by-step explanation:
*I thinks you have made a mistake with the unit of the volume*
Density = mass / volume
density = 6 g/cm³volume = 34 cm³Mass = volume * density
mass = 6 * 34

Which equation would demonstrate the identity property? A. (3 • 4) + (3 • 5) = 3(4 + 5) B. 3 • 5 = 5 • 3 C. 3 • 4 • 5 = (3• 4) • 5 D. 4 • 1 = 4
Answer:
D. 4 • 1 = 4
Step-by-step explanation:
In Mathematics, we have two kinds of Identity property
a) Identity property of Addition
This means that when you add a number to zero, it gives you that same number
Example: 6 + 0 = 6
b) Identity property of Multiplication,
This means that, when a number is multiplied by 1, it gives that same number.
Example: 8 × 1 = 8
Therefore, from the above question, the equation that demonstrates identity property is 4 • 1 = 4

be a good fit while an exponential would be reasonable.?
Answer:
hello the table related to this question is missing attached below is the missing table
answer : An exponential function is much better fit because there is no fixed rate in the table
Step-by-step explanation:
An exponential function is much better fit because there is no fixed rate in the table attached but the values in the table keeps increasing exponentially, hence an Exponential function will be a better fit, But a linear function would be preferred only if there is a fixed rate

Give each side and angle measure rounded to the nearest whole number
Answer:
Step-by-step explanation:
A—>108m
B—>180m
M<B—> 59°
The side BC and AC and the angle B is 108 m,180 m and 59°.
What is the triangle?A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
[tex]\rm sin \theta = \frac{P}{H} \\\\ \rm sin 31^0= \frac{a}{210} \\\\ a=108 \ m[/tex]
[tex]\rm cos \theta = \frac{B}{H} \\\\ \rm cos 31^0 = \frac{b}{210} \\\\ b=180 \ m[/tex]
The measure of the angle of triangle is 180°
∠A+∠B+∠C=180°
31°+∠B+90°=180°
∠B=59°
Hence, the side BC and AC and the angle B is 108 m,180 m and 59°.

seven people sit in a circle.How many ways can this be done if two people A and B sit together
Step-by-step explanation:
Suppose the persons are a, b, c, d, e, f and g.
Let us also assume that a and b always sit together.
Let us then put the remaining 5 persons in a circular arrangement. It can be done in (5–1)! = 4! = 24 ways. Now, the pair (a,b) can be placed between any two persons already placed in circular order. There are 5 such gaps. Finally the pair (a,b) can be placed in two ways viz. (a,b) and (b,a).
So, total number of ways a group of 7 persons can be seated around a circular table where 2 specified persons always sit together is 24 X 2 X 5 = 240

Answer:
bro what is even happening here
so confused but okay
Answer:
∠ LHJ = 10°
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180°
Then
∠ KLH + ∠ LHJ = 180°
170° + ∠ LHJ = 180° ( subtract 170° from both sides )
∠ LHJ = 10°

In the given diagram, the value of x is 15
Pythagorean theoremThe Pythagorean theorem states that, in a right triangle, the square of the longest side (hypotenuse) equals sum of squares of the other two sides
From the question, we are to determine the value of x.
x is the radius of the circle
Recall: Radius is any line that runs from the center to any part of the circumference
Consider the right triangle formed, x is the hypotenuse
By the Pythagorean theorem,
x² = 9² + 12²
x² = 81 + 144
x² = 225
x = √225
x = 15
Hence, the value of x is 15.
