The distance around a triangle is 34 centimeters. If two sides are equal and the length of the third side is 6 centimeters, what is the length of each of the other two sides?
Answers
Subtract 6 from the total then divide by 2.
34-6 = 28
28/2 = 14
The length of the other two sides are 14 cm each
28 divided by 2 = 14
So, the length of the two other sides is 14 centimeters.

x = 124 degree
Step-by-step explanation:
Sum of all interior angles of triangle = 180
69+55= 124
Therfore third angle, 180-124= 56
Linear pair= 180

Step-by-step explanation:
First find the area in black in total
190 x 48 = 9120
then find the area of the two squares
34 x 34 = 1156
1156 x 2 = the two square combined = 2312
subtract the total area in black with the area of the combined squares
9120 - 2312 = 6808

votes would you expect to receive?
Answers
Answer:
~600 votes
Step-by-step explanation:
Notice how 900 is a multiple of 3. Multiplying by 2/3 is the same as saying as divide the total by 3, then multiply that result by 2. Thusly, 900/3=300 and 300*2=600. Therefore, you should expect around 600 votes.

In a sewage treatment plant, a large concrete tank initially contains 440,000 liters of liquid and 10,000 kg of fine suspended solids. To flush this material out of the tank, water is pumped into the vessel at a rate of 40,000 l/h. Liquid containing solids leaves at the same rate. Estimate the concentration of suspended solids in the tank at the end of 4 h. You can assume that the initial concentration of solids in the tank
Answers
Answer:
[tex]Concentration = 8.26kg/m^3[/tex]
Step-by-step explanation:
Given
[tex]V = 440000L[/tex] --- volume of tank
[tex]m = 10,000 kg[/tex] --- solid mass
[tex]r = 40000L/hr[/tex] --- outflow rate
Required
Determine the concentration at the end of 4 hours
First, calculate the amount of liquid that has been replaced at the end of the 4 hours.
[tex]Amount = r * Time[/tex]
[tex]Amount = 40000L/hr * 4hr[/tex]
[tex]Amount = 40000L * 4[/tex]
[tex]Amount = 160000L[/tex]
This implies that, over the 4 hours; The tank has 160000 liters of liquid out of 440000 liters were replaced
Calculate the ratio of the liquid replaced.
[tex]Ratio = \frac{Amount}{Volume}[/tex]
[tex]Ratio = \frac{160000L}{440000L}[/tex]
[tex]Ratio = \frac{16}{44}[/tex]
[tex]Ratio = \frac{4}{11}[/tex]
Next, calculate the amount of solid left.
[tex]Amount (Solid)= Ratio * m[/tex]
[tex]Amount (Solid)= \frac{4}{11} * 10000kg[/tex]
[tex]Amount (Solid)= \frac{40000}{11}kg[/tex]
[tex]Amount (Solid)= 3636kg[/tex]
Lastly, the concentration is calculated as:
[tex]Concentration = \frac{Amount (Solid)}{Volume}[/tex]
[tex]Concentration = \frac{3636kg}{440000L}[/tex]
Convert L to cubic meters
[tex]Concentration = \frac{3636kg}{440000* 0.001m^3}[/tex]
[tex]Concentration = \frac{3636kg}{440m^3}[/tex]
[tex]Concentration = 8.26kg/m^3[/tex]

Pete is packing toys into boxes. Each box holds 30 toys. There are 94 toys and 3 boxes. How many extra toys are there?
Answers
Answer:
There are 4 extra toys.
Step-by-step explanation:
Hey there!
We're given the following information:
There are 94 total toys.There are 3 boxes.Each box will hold 30 toys.Therefore, we can realize that this will be a division problem since something is being put into another item:
Lone toys → toys in boxesWe have 3 boxes that will fit 30 toys each, so let's find out how many toys are accounted for with these boxes.
[tex]30 \times 3 = 90 \ \text{toys}[/tex]Now, we can just subtract the total number of toys from the accounted amount of toys.
[tex]\text{94 total toys - 90 accounted toys = 4 remaining toys}[/tex]Therefore, we know that remaining is a synonym of extra, so there are a total of four toys that are left over.
Answer:
4
Step-by-step explanation:
90/30 = 3 boxes
94-90 = 4 extra boxes

Answers
Answer:
Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.
Step-by-step explanation:
Since Alfred departs from NAMPO Park at 18:45 and travels to Sasolburg at an average speed of 88 km / h, and he calls his wife to inform her that he will arrive in Sasolburg at 8 pm, to determine if his estimate is correct the following calculations must be performed:
The shortest route from Nampo Park to Sasolburg in South Africa is 139 km via Route 59.
8 PM = 20:00
20:00 - 18:45 = 1:15
139/88 = 1.57
60 x 0.57 = 34.74
Thus, Alfred will not arrive in his city at 8 PM, but he will arrive at approximately 8:20 PM.

A chi-square test of independence was conducted to investigate whether there is an association between the location where a person lives in a city (north, south, east, or west) and who the person planned to vote for in the upcoming mayoral election (the incumbent or the challenger). A random sample of 100 potential voters was selected, and the hypothesis test had a chi-square test statistic of χ2=9.84 with a p-value of 0.02. Which of the following statements is the correct interpretation of the p-value in context?
(A) There is a 2 percent chance that where a person lives and who that person plans to vote for are independent.
(B) There is a 2 percent chance that where a person lives and who that person plans to vote for are dependent.
(C) There is a 2 percent chance of making a Type II error.
(D) Assuming that the location of where a person lives and who that person plans to vote for are dependent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.

We need to find [tex]x[/tex] which will make an equivalent fraction statement.
[tex]\frac{5}{x} = \frac{30}{54}[/tex]
5 x 6 = 30
[tex]x[/tex] x 6 = 54 (to find [tex]x[/tex] we should do 54 ÷ 6 which = 9)

Here are summary statistics for randomly selected weights of newborn girls: n=250, x_=32.9 hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 31.9 hg < μ < 34.5 hg with only 19 sample values, x_=33.2 hg, and s=2.6hg? What is the confidence interval for the population mean μ?
Answers
Answer:
a) ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) ( 31.74 , 34.66 )
Step-by-step explanation:
n = 250
x ( mean ) = 32.9
std = 6.9
95% confidence interval
df = n - 1 = 250 - 1 = 249
a) construct confidence interval estimate
calculate for the margin of error
= [tex]t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )[/tex] ( using excel function: T.INV.2T(0.025,249) )
= 2.255 ( 6.9 / 15.81 )
= 0.98
Hence the confidence interval for the population
= ( x - 0.98 < μ < x + 0.98 )
= ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) when n = 19
x = 33.2 and std = 2.6
margin of error = [tex]t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )[/tex] = 2.45 * ( 2.6 / 4.36 ) = 1.46
confidence interval
= ( 33.2 - 1.46 , 33.2 + 1.46 )
= ( 31.74 , 34.66 )
