In ABC, angle A = 30 degree , angle b=45 degree find the angle c
Answer:
95 degrees
Step-by-step explanation:
in a triangle angles add up to 180 degrees.
a + b + c = 180
30 + 45 + c = 180
85 + c = 180
c= 180 - 85
c= 95 degrees
What is the mean of the data 25, 27, 24, 26, 40 and what is the median
Answer:
mean is = 28.4
median is = 26
Step-by-step explanation:
mean- average
( 25+ 27+ 24+ 26+ 40 )/5 = 28.4
median- middle
25, 27, 24, 26, 40
{ rearrange }
24, 25, 26, 27, 40
the middle number is 26
Nicolas sold 86 newspapers on Monday 79 on Tuesday and 68 on Wednesday and 83 on Friday how many newspapers did Nicholas sell on Thursday if he sold a total of 391 in five days?
Define a variable, write an equation, then solve.
Answer:
75
Step-by-step explanation:
86+79+68+83=316
391-316=75
Answer:
75 newspapers
Step-by-step explanation:
391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:
391 = 86 + 79 + 68 + 83 + x
x represents the number of newspapers Nicholas sold on Thursday.
Now let's solve for x:
First, combine like terms:
391 = 316 + x
now subtract 316 from both sides to isolate x:
391 - 316 = 316 - 316 + x
75 = x
Nicholas sold 75 newspapers on Thursday.

Answer: yes
Step-by-step explanation:
Answer:
Yes, he has enough money to get his things.
Step-by-step explanation:
3 (the amount of grass seed bags he's buying) x 23 (how many dollars it costs) = 69
3 (the amount of flower pots he's buying) x 15 (how many dollars it costs) = 45
69 + 45 = 114
He will have $6 left over his purchases.

Evan is going to the county fair this weekend. The admission to the fair is $5 and the cost per ride is $.50. Write and solve a linear equation to find out how many rides he can go on.
Answer:
Evan can go on 30 rides (based on the assumption that Evan's parent gave him $20)
Step-by-step explanation:
Given that:
The admission to the fair = $5
The cost per ride = $0.50
Let assume that the number of ride Evan can go = x
So if The cost per ride = $0.50
x ride = $0.50x
We are not told that he is given money by anybody, but let assume his parent gave him $20,
Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left
The relation expressing how many rides Evan can go is:
0.5x = 15
Since the cost per ride = $0.5
x rides cost $15/0.5
x = 15/0.5
x = 30
Hence, Evan can go on 30 rides
four ninths plus nine eighteenths :]
Answer: 17/18
In words, this is seventeen eighteenths
==========================================
Work Shown:
4/9 + 9/18
8/18 + 9/18 ... see note below
(8+9)/18
17/18
----------------
note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.
The diagram below shows a visual representation of why 4/9 = 8/18.
In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
Answer: its 17/18

In 1980, the population of a town was 2000 people. The exponential function P(t)=2000(1.05)t models the population of the town since 1980. Which statements are true regarding the population of the town? Select THREE that apply.
A.
The population has increased by 5% each year since 1980.
B.
The population has increased by 105% each year since 1980.
C.
The population has increased by 5 people each year since 1980.
D.
Each year since 1980, the population is 105% of the population of the previous year.
E.
Each year since 1980, the population is 1.05 times the population of the previous year.
Answer:
B. The population has increased by 105% each year since 1980.
D. Each year since 1980, the population is 105% of the population of the previous year.
E. Each year since 1980, the population is 1.05 times the population of the previous year.
Step-by-step explanation:
From the question, we are given the exponential function:
The exponential function P(t)=2000(1.05)^t models the population of the town since 1980.
Exponential growth rate =
P(t) = P(1 + r)^t
Where r = growth rate in percentage
P(t) = Size of the population after t years
t = time in years
Hence,
From the formula above, we can say =
1 + r = 1.05
r = 1.05 - 1
r = 0.05
Converting to percentage = 0.05 × 100 = 5%
1.05 can also converted to percentage and this = 1.05 × 100 = 105 %
The population has increased by 105% each year since 1980.
Hence, Options, B, D and E is correct

If an odd number is less
than 15, then it is prime.
Answer: That is false
Step-by-step explanation: 9 is odd but not prime
The statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
If an odd number is less than 15, then it is prime.
As we know,
The prime number is the number that has factors only 1 and itself the number.
The odd number is less than 15.
The odd number is less than 15 = {13, 11, 9, 7, 5, 3}
The statement "If an odd number is less than 15, then it is prime" is false
Because the number 9 is not prime.
Thus, the statement "If an odd number is less than 15, then it is prime" is false because the number 9 is not prime.

what is the vaule 7 to the 6 power
Answer:
117,649
Step-by-step explanation:
Good luck! <3
Answer:
7 to the 6th power is conventionally written as 76, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 7^6.
76 stands for the mathematical operation exponentiation of seven by the power of six.
As the exponent is a positive integer, exponentiation means a repeated multiplication:
The exponent of the number 7, 6, also called index or power, denotes how many times to multiply the base (7).
Thus, we can answer what is 7 to the 6th power as
7 to the power of 6 = 76 = 117649.

The two different quantities to measure which school has higher academic performance are:
Graduation rate / Budget per studentSAT average / Budget per studentHow to illustrate the information?The parameters which could be used to measure academic achievement are the graduation rate of each school he SAT average of each school.
Therefore, defining the quantity to measure academic achievement relative to budget per student could be expressed as the graduation rate divided by the budget per student. It can also be the SAT average divided by the Budget per student.

There are two types of cellular phones, handheld phones (H)that you carry and monile phones (M) that are mounted invehicles. Phone calls can be classified by the travelingspeed of the user as fast (F) or slow (W). The probabilitymodel for this experiment has the following information: P[F] =0.5, P[HF] = 0.2, P[MW] = 0.1. What is the sample space ofthe experiment? Calculate the followng probabilites:a) P[W]b) P[MF]c) P[H]
Answer:
Explained below.
Step-by-step explanation:
(1)
Sample space is a set of all possible outcomes of an experiment.
The sample space in this case is:
S = {HF, HW, MF, MW}
(a)
Compute the value of P (W) as follows:
P (F) + P (W) = 1
P (W) = 1 - P (F)
P (W) = 1 - 0.50
P (W) = 0.50
(b)
Compute the value of P (MF) as follows:
P (HF) + P (MF) = P (F)
P (MF) = P (F) - P (HF)
P (MF) = 0.50 - 0.20
P (MF) = 0.30
(c)
Compute the value of P (M) as follows:
P (M) = P (MF) + P (MW)
P (M) = 0.30 + 0.10
P (M) = 0.40
Compute the value of P (H) as follows:
P (H) + P (M) = 1
P (H) = 1 - P (M)
P (H) = 1 - 0.40
P (H) = 0.60

11) Is the following biconditional true? Explain. Two people are brother and sister if-and-only-if they are siblings.
Answer:
Well, not exactly.
Step-by-step explanation: You see, there's this thing called half siblings. They aren't exactly quite any different to normal siblings, except the fact that they either have the same mother and different father, or the same father and different mother. This usually results after a mother and a father divorce, or their respected love one dies, and they have children. The mother/father then can remarry, and when their wife/husband also has a child. The two or more children become half siblings. Also, if we're gonna talk not literal siblings. Close friends often like to think of each other as siblings, though they aren't biologically siblings. Half siblings and step sisters are two different things, half is where your sibling shares half your genes, and step siblings are where they don't have any of your genes and only their respected parent's genes. Now depending on if they mean biologically siblings, I would say true. But if they count all, then it would be false.
