Find the measure of the indicated angle to the nearest degree
Answer:
30
Step-by-step explanation:
I see that the square in the triangle is a right triangle, so it's automatically a 90 degrees. the triangle should add up to 180, so I figured that since we have 90, we just needed to find the other angles that help add up to that, which is 60 and 30

6. We want to build the smallest cube possible using bricks with dimensions 8 cm - 12 cm 20 cm. How many bricks do we need?
Answer:
1200
Step-by-step explanation:
We’ll need a number that is evenly dividable by all three values: 8,12 & 15. We can develop the generic common multiple by multiplying all three numbers and get 1440. But is that the smallest common multiple? The quick and dirty way to factor the number is to divide it by it’s various elements and see what works. In this case 1440/12=120 which is the smallest common multiple of the three numbers. The smallest length is therefore 120.
In order to find how many bricks just divide (120x120x120)/(8x12x15)=1200 bricks

Solve Me Mobiles puzzle #20 I need help please I'll give 36 points. I just need help trying to solve this puzzle!!!!
Answer:
Pink Trapezoid = 15
Green Cresent = 11
Step-by-step explanation:
The total weight of the mobile is 30.
Because the mobile is evenly balanced between both sides, and we know the diamonds weigh 2 each, we can use simple math tofind the values of the other shapes.
So the total weight (30) divided by the 2 sides = 15 on each side.
This means the pink trapezoid weighs 15 and the rigt side weighs 15.
So 15 - 2 - 2 = 11
So the green Crescent weighs 11.

Answer:
108 cm^2
Step-by-step explanation:
rectangle + 2 triangle = total area
L x W + 2 * 1/2 base * height = total area
(5x12) + 2 * 1/2 * 12 * 4 = total area
60 + 48 = 108 cm^2
Answer:
108 cm²
Step-by-step explanation:
To do:
1. find area of rectangle 2. find area of triangles 3. add them together
area of a rectangle = bxh = 5x12 = 60
area of triangle = (bxh)/2 = (12x4)/2 = 24
60+24+24=108

Solve for x.
X=?
5x-16 x+10
Answer:
The answer is x= 31
Step-by-step explanation:
(5x-16)+ (x+10)= 180 (Linear Pair)
Now, open the brackets
5x-16+x+10= 180
Arrange the like terms together
5x+x-16+10= 180
=> 6x-6= 180
=> 6x= 180+6
=> 6x= 186
=> x= 186/6 = 31
∴x= 31

[tex]A = 72\ units^2[/tex]
Step 3: Determine the hypotenuse
Pythagorean theorem → [tex]a^2 + b^2 = c^2[/tex]
[tex]12^2 + 9^2 = c^2\\[/tex]
[tex]144 + 81 = c^2[/tex]
[tex]225 = c^2[/tex]
[tex]\sqrt{225} = \sqrt{c^2}[/tex]
[tex]15 = c[/tex]
Step 4: Determine the area of the top
[tex]A = l * w[/tex]
[tex]A = 15\ units * 8\ units[/tex]
[tex]A = 120\ units^2[/tex]
Step 5: Determine the area of the triangles

10. A sphere has a volume of 7,234.56 units?. Using 3.14
for pi, find the radius of the sphere. Record your answer
on the grid.
The radius of the sphere has a volume of 7,234.56 units^3 is 1728 units.
We have the sphere has a volume of 7,234.56units^3
V=7,234.56units^3
What is the formula for the volume of a sphere?
[tex]V=(4/3)(pi)(r^3)[/tex]
Where r is the radius.
Solving this for r^3, we get
[tex]r^3=\frac{V}{(4/3)(pi)}[/tex]
[tex]r^3=\frac{V}{(4/3)(3.14)}[/tex]
[tex]r^3=\frac{7,234.56}{4.19}[/tex]
[tex]r=1728[/tex]
Therefore we get the radius of the sphere is r = 1728 units

You are buying bags of flour and bags of sugar for a bakery. You must buy three times as many bags of sugar as there is bags of flour. Also, you are on a budget of $720. Of flour costs $6 per bag and sugar costs $4 per bag, how many bags of flour and how many bags of sugar can you buy
The number of bags of flour would be 40.
And, the number of bags of sugar would be 120.
Given that,
You must buy three times as many bags of sugar as there are bags of flour.
And, you are on a budget of $720. Flour costs $6 per bag and sugar costs $4 per bag.
Let us assume that,
The number of bags of flour = x
And, the number of bags of sugar = y
Hence, we get;
y = 3x .. (i)
And, 6x + 4y = 720 .. (ii)
Substitute x = 3y in (ii);
6x + 4 (3x) = 720
6x + 12x = 720
18x = 720
x = 720/18
x = 40
From (i);
y = 3 × 40
y = 120
Thus, The number of bags of flour = 40
And, the number of bags of sugar = 120

Anything of the form [tex]x^0[/tex] will be equal to 1, whenever x is nonzero.
So [tex]5^0 = 1[/tex]
All of the answer choices mentioned simplify to 1. Dividing any nonzero value over itself yields 1, so that explains A and B.

Use the Distributive Property to solve: 4(x + 2) = 32
Answer:
The value of x = 6
Step-by-step explanation:
=> 4(x + 2) = 32
=> 4x + 8 = 32
=> 4x = 32 - 8
=> 4x = 24
=> x = 24/4
=> x = 6
A 95 % confidence interval for the proportion of democrat voters in the State of Florida based on a poll is (0.34, 0.43). Based on this confidence interval, is it reasonable to claim that less than 45 % of Floridian voters are democrats
Reason:
The confidence interval for the population proportion p is (0.34, 0.43)
This is equivalent to saying 0.34 < p < 0.43
We're 95% confident p is somewhere between 0.34 and 0.43
Both of these endpoints are smaller than 0.45, meaning that all of the proportions p in the interval are smaller than 0.45
So it's fairly reasonable to assume that less than 45% of the Floridian voters are democrats (since it seems to be between 34% and 43%). Keep in mind that there's always a margin of error with statistics, so we cannot say this with 100% certainty.
Yes, it is reasonable to claim that less than 45 % of Floridian voters are Democrats.
How to calculate a confidence interval for the population mean for a small sample?If the sample size is given to be n < 30, then for finding the confidence interval for the mean of the population from this small sample, we use a t-statistic.
Let the sample mean given as[tex]\overline{x}[/tex] and
The sample standard deviation s, and
The sample size = n, and
The level of significance = [tex]\alpha[/tex]
Then, we get the confidence interval in between the limits
[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}}[/tex]
where, [tex]t_{\alpha/2}[/tex] is the critical value of 't' that can be found online or from tabulated values of critical value for a specific level of significance and degree of freedom n - 1.
The confidence interval for the population proportion p is given as (0.34, 0.43)
This is equivalent to 0.34 < p < 0.43
We're 95% confident that p is somewhere between 0.34 and 0.43
Both of these endpoints are smaller than 0.45, seems that all of the proportions p in the interval are smaller than 0.45
So it's fairly reasonable to assume that less than 45% of the Floridian voters are Democrats. So there's always a margin of error with statistics, so we cannot say this with 100% certainty.

A computer is programmed to generate a sequence of three digits, where each digit is either 0 or 1, and each of these is equally likely to occur. construct a sample space that shows all possible three-digit sequences of 0s and 1s and then find the probability that a sequence will contain exactly one 0. a. 000, 001, 010, 011, 100, 101, 110, 111; the probability is startfraction 7 over 8 endfraction. b. 001, 011, 101, 111; the probability is startfraction 2 over 8 endfraction. c. 000, 010, 011, 101, 111; the probability is startfraction 2 over 8 endfraction = one-fourth. d. 000, 001, 010, 011, 100, 101, 110, 111; the probability is startfraction 3 over 8 endfraction.
The probability that a sequence will contain exactly one 0 is 3/8.
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1,
We should consider sequences of three digits, where each digit is either 0 or 1. A sequence has three places .
where each place has two possibilities, i.e., 0 or 1, so, for the multiplication rule
we know that the sample space will have (2)(2)(2) = 8 sample points.
Specifically, the sample space is
S = {111, 110, 101, 011, 100, 010, 001, 000},
There are three sequences with exactly one 0.
Therefore the probability that a sequence will contain exactly one 0 is 3/8.
