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

Answer: 3) volume= 28ft³
Surface area= 64ft
4) Volume= 24mi²
Surface area= 192mi
Step-by-step explanation:
3) Volume= length x width x height
= 7x2x2
= 28ft³
Surface area= [(2x2)x2]+[(7x2)x4]
= 8+56
=64ft
4) Volume= 1/2 x length x base x height (whenever finding the areas of triangular shapes you should multiply it by 1/2)
continuation;
= 1/2 x 8 x 6
= 1/2 x 48
= 24 mi³
Surface area= (1/2 x 8 x 6 x 2)+(6 x 6)+(10 x 6)+(8 x 6)
= 48 + 36 + 60 + 48
= 192 mi

which graph represent the liner function y= 1/3 x -4?
Answers
Answer:
Graph 3
Step-by-step explanation:
equation: y = mx + b → y = 1/3x - 4
- m is the slope (slope = rise / run):
- b is the y intercept (when x = 0): -4
Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4
Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1
the correct equation for this graph is y = 3x - 4
Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3
and the y intercept is -4
Graph 4 is incorrect because the y-intercept is not even shown

=1/2*10*24

=120units sq
Step-by-step explanation:
The semi-perimeter is:
s = (a + b + c) / 2
= (10 + 24 + 26) / 2
= 47
We will find the area of the triangle using the Heron's formula.
A = √[s (s - a) (s - b) (s - c)]
= √[47 (47 - 10) (47- 24) (47 - 26)]
= √10 × 37 × 23 × 21

FEET 1 4 5
INCHES 24 36
Answers
Answer: feet: 1, 2, 3, 4, 5
inches: 12, 24, 36, 48, 60
Step-by-step explanation:
There are 12 inches in a foot, therefore if you have 1 foot you have 12 inches, if you have 2 feet you have 24 inches becauase 2*12 = 24 and so on...
To find how many inches = the amount of feet you would simply multiply the number of feet by 12.
For example 4ft would be 4x12=48. Or 5ft would be 5x12=60
Therefore 4ft =48inches. And 5ft =60inches
If u are given an amount in inches to determine feet you would divide by 12
For example
84 inches into feet would be solved by dividing 84by 12
84/12=7
you now know that 84inches =7feet

Answers
1) Correct option is C)
A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.
The experimental probability of getting a head is :
P(E)=
Total outcomes divided by Number of head
58/100 = 29/50 (29/50x100) = 58% (C)
2) 19%
Answer:
1. 42%
2. 33%
Step-by-step explanation:
1. Relative frequency = Number of successful trials ÷ Total number of trials
plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%
2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials
plug the numbers in and we get 2/6 = 1/3 = 33%

How do i write mixed numbers as an improper fraction?

Answers
Answer:
A mixed fraction can be written as an improper fraction by multiplying the whole number with the fraction's denominator and adding that to the numerator, and finally writing that result on top of the denominator.
Step-by-step explanation:
Answer:
You have to multiply the whole number by the denominator and then add the answer you get with the numerator.
Step-by-step explanation:
For example, the fraction 10 [tex]\frac{1}{3}[/tex] is a mixed number right? So then you multiply 10x3=30. Then you add 30+1=31. So then the answer would be [tex]\frac{31}{3}[/tex].

If the mean of the data set is 3.533. Then the mean absolute deviation for the data set will be 1.831.
How do find the mean absolute deviation of discrete data?Suppose the data specified is of n sized as
[tex]\rm x_1, x_2, \cdots , x_n[/tex]
Let this data's mean will be μ
Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.
It is calculated as:
[tex]\rm M.A.D = \dfrac{\sum_{i=1}^n|x_i - \mu|}{n}[/tex]
The data set is given below.
3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6
Then the mean of the data will be
Mean = (3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6)/15
Mean = 53/15
Mean = 3.533
Then the mean absolute deviation for the data set will be
[tex]\rm M.A.D = \dfrac{|3-3.533| + |5-3.533| + |6 - 3.533| + |3 - 3.533| + ...+|6-3.533|}{15}[/tex]
M.A.D. = 27.4665/15
M.A.D. = 1.831111

What is the circumstance of the circle? (3.14 for pi)
Answers
Answer:
131.88in
Step-by-step explanation:
C = 2πr
The radius of the circle is from center to the perimeter.
In this case the radius is 21in.
3.14 for pi
C = 2(21)(3.14)
C = 42(3.14)
C = 131.88in
Answer:
the answer for this question should be 131.88 because 21 is the radius and the radius is half of the diameter which is 42 because you need to multiply 21 times 2 getting an answer for the diameter but we use the formulas.
C=2 times 3.14 times 21= 131.88
C= 3.14 times 42=131.88
